1. Introduction
The chassis armor chassis scientific name collision noise rust coating “UNDERCOATING” (primer), a rubberized asphalt adhesive coating is a high-tech vehicle chassis development Floor.
2, features
chassis rust products have been developed so far to the fourth generation, the first generation of “single molecule paint solvents” include pitch 
⒈ chassis corrosion: corrosion car all start from the floor, Do not you see, only ran three to five years of automobile side beam has begun to glow rust. South had more than wet weather, plus every time you wash water will be left at the bottom, it will go a long form potential corrosion factors, causing damage to the car. After the bottom of your car maintenance, even acid rain, melting snow agents, alkaline washing can not be eroded through this layer of protective film, giving you a peace of mind.
⒉ anti-stoning: vehicles in the process, will be thrown pebbles, gravel impact strength is proportional to the floor with your speed, generally 10 grams pebbles at the speed of 80 km to reach their own impact 30,000 times the weight, it is equivalent to touch the eggs with stones it! 30 microns or less is sufficient to break the film, the film once defects begin to break corroded and slowly begins to expand from the internal iron. After the bottom of your car maintenance, then even gravel to 300 kg impact force can not break it, giving you a peace of mind.
⒊ shock: the engine, the wheels are fastened to the vehicle floor, they will resonate with the vibration plate at a certain frequency, gives rise to discomfort, bottom guard will eliminate this resonance, giving you a soothing .
⒋ insulated fuel: In the summer, the surface facing the high temperature, it is easy to put the car chassis to the heat-conducting vehicle. If the car open air, it will need more fuel to reduce the temperature inside the vehicle. If the armored vehicle chassis mounting, may be a large degree of cut off from outside the heat and keep the temperature inside the car, thereby reducing oilConsumption. According to the sinking cold air, hot air rises principle, air-conditioning manufacturing to sink, and the ground outside the car to heat rising, hot and cold air mostly concentrated on the floor of the vehicle to be exchanged, how the vehicle bottom protective effect, directly determines how to use the energy of the vehicle refrigeration effect, after the bottom of your car maintenance, its sound-absorbing tissue membrane cellular factor will completely isolate the hot and cold, but also you a fresh green of summer.
⒌ noise reduction: the vehicle is traveling at speed friction sound and rapid way, with the road wheel is proportional to the vehicle with intact bottom guard can greatly reduce interior noise, gives you a quiet.
⒍ anti-drag bottom: Anti-dragging at the end: different road conditions, will inevitably encounter a raised place, if the increase in the armored vehicle chassis, it is possible to prevent wear and tear of the vehicle chassis, protecting car chassis to a greater extent. Curing the material thickness of the bottom up to 1.5-2.5 mm, the projections being scratched when the bottom surface, will reduce the damage to the chassis, especially when high-speed running, a pleasant to you.
maintenance costs ⒎ province, hedge car: Because the car chassis supports four systems, chassis protection equal protection of the various systems above, saving a series of maintenance fees to be generated. New car usually used for about three years, corrosion occurs. Correspondingly, while the fact is: the better vehicle maintenance, the higher the value. After running for some time, whether their own use or to prepare for a new car, after a solid shield chassis protective treatment (in particular, large companies have formal quality assurance) car certainly has a higher value.
3, the use of
for the range
armored chassis is very broad, often considered the applicable hardware, application conditions and precautions.
One suitable hardware. Suitable hardware chassis armor are many and various automobile chassis, automobile frames, bumpers, rust soundproof hood, automotive, shipbuilding, machinery, and various metal surfaces may be used, generally require insulating air steel are You can use chassis armor products from economic considerations, usually senior mechanical plate car before choosing to use armored chassis.
2. Conditions. Only you need to do the chassis armor under what circumstances? How to determine whetherThe chassis plate armor?
(1) For the new car. Due to the circumstances of each brand of vehicle chassis protection is not the same, as far as possible the owner asked to see the new cars rose chassis. Conditions were not lift car can touch the chassis has been done to know whether protection. If you feel there is a layer of plastic glued to the bottom of the vehicle, flexible, indicating that protection is done. The touch to the cold hard steel, described do not protective. Particular attention to check vehicle wheel arc, and the inner fender place is connected with a protective steel, etc., which are usually missed key parts manufacturers. Also check to see if the chassis is simple protective material similar to bituminous materials, asphalt material dry hard, lack of flexibility, easy to fall off, the protective effect of the chassis is very limited. In these cases, we need to do the chassis armor.
(2) For cars. Generally older cars are not protected armored chassis, since the early years, chassis armor product has not yet appeared (hehe). The chassis can first check whether there is a protective layer? First chassis cleaning, if you see a clear rust chassis, designated horizontal trace; and want to have a better car driving experience, then you can choose to use the preferred channel UD chassis armor products.
(3). Note. When doing a chassis armor to be given attention to the following points
First of all, we must go to a special shop construction and construction professional and technical personnel of the regular stores. At the same time after the completion of armor, the owner must not forget to ask chassis rust construction quality assurance certificate store construction, in order to safeguard their legitimate rights and interests. Regular stores are generally committed 1–3-year warranty, during this period because of the loss of the reasons underpinning, etc. can also be repaired for free.
Second, avoid construction under rainy weather conditions. Because it is not conducive to the timely drying paint, often directly affect the actual results chassis armor.
Finally, after the completion of construction chassis armor, preferably about 1 day to not place with poor road conditions, because the coating material has not been sufficiently dried, the effect has not yet reached full cure.
4, using the method according to
Step 1, increased automobile, rinsed with water cannons chassis, first painted or outside the engine cleaner engine degreaser removal chassisThe bonded sand and sludge, with a special sandpaper or sanding off the primary rust-preventive layer; Step 2, with a gap Chit water gun blowing, the water and towel dry. Step 3, ready to spray rust-proof layer must be covered with a paper (multipurpose paper) and the adhesive tape, the periphery of the tire and an exhaust pipe cover, with particular attention to the vehicle body and a shock absorber for a sensor covered. Step 4, armor chassis component materials are sequentially sprayed in the end plate, at least three spray layer, a thickness of about 4 mm. Step 5, the local repair coating, the better to ensure that the stronger shield; Step 6, the periphery of the shield is removed, with a special non-detergent spraying peripheral portion, wait dried, car about 1 hour to somehow, used cars is necessary according to the vehicle condition.
5, the role of
What is the role of an armored vehicle chassis: anti-knock; the vehicle is in motion, some of gravel will inevitably splashes, further to the car chassis caused by percussion. Go on for a long time, will cause greater damage to the vehicle chassis. But after the armored vehicle chassis installation, the gravel to avoid hitting the car on the chassis, thereby protecting sound good car chassis.
What is the role of the armored vehicle chassis II: Anti-dragging bottom; in different sections, it is inevitable there will be some bumps in place will cause wear and tear the car chassis. If you increase the armored vehicle chassis, it is possible to prevent wear and tear of the vehicle chassis, protecting car chassis to a greater extent.
What is the role of armored vehicle chassis of three: anti-corrosion; more rainy season in the south, while driving, it is easy to put the acid rain spilled into the chassis, go on for a long time, will cause corrosion of the car chassis. And each will have the sewage residue after washing, further corrosion car chassis. Armored vehicle chassis to install these unnecessary corrosion is avoided.
What is the role of four armored vehicle chassis: insulation; in the summer heat, the face of a high surface temperature, it is easy to put the car chassis to the heat-conducting vehicle. If the car open air, it will need more fuel to reduce the temperature inside the vehicle. If the armored vehicle chassis mounting, may be a large degree of cut off from outside the heat and keep the temperature inside the car, thereby reducing fuel consumption.
6, factors
there are three, one is the most critical material; the second is the construction process; the third is to consider whether the formal beauty shop.
7, the development of prediction
In 2002 China car modification industry output value of 500 million yuan, in October 2008 had risen to 2.5 billion yuan – car modification industry into a new growth point . In 2007 China modified car market has a capacity of 1.3 billion -15 billion, while in 2015, will reach 140 billion yuan. As China’s auto market to mature, more professional, with strong support from car manufacturers based car modification market will soon appear. Chinese car manufacturers will never give up such a huge market. 2009 is expected to bring the Chinese car modification market efficiency could reach $ 20 billion. Chinese car modification industry will show a huge increase and will become an important part of the automobile industry chain. With the Chinese government’s policy of continuous relaxation, increase consumer personal income, as well as modification of the demand for personalized, China modified car market to expand in the next five years will become a multiple.
8, maintenance trend
chassis armored target consumer groups to the new owner. Abroad chassis rust are highly valued, because it will destroy the original frame supporting force, automobile consumption more mature areas, car floor and over 90 percent of the owners first thing chassis rust. “Armored chassis” is essential for high-end cars, like when Mercedes-Benz, BMW these high-end car factory will have a fairly complete chassis protective measures. China’s auto market has become increasingly active, and gradually raise awareness of domestic car owners to protect the chassis, more and more people realize the importance of the chassis care.
external analysis: Experts predict that by 2010, China’s car ownership will reach 20.7 million, which shows that the car will be the next few years consumptionHighlights. China has developed rapidly in major cities, but the construction is not complete, the car park is quite scarce, a lot of cars can only open-air habitat, but unfortunately suffered the invasion of wind and rain and sun, resulting in an aging car. Most of the car because of cost considerations, only a partial simple rust treatment, these low levels of anti-rust treatment, not simply from the rust. The rapid development of China’s national auto industry, as well as people’s consumption level is growing, so that privately owned cars has become a reality. It is estimated that every 1 yuan 0.65 yuan car consumption will drive the car service. In recent years, consumption of cars continue to rise, while the average consumer knowledge of car maintenance is very limited, which means professional, standardized, high-quality automotive service industry, will be enormous potential for development in the future of the automotive consumer market .
According to the national information Center data show: China 1996 total vehicle sales to an annual 15 percent rate of increase in demand for cars, which will span 100-200 ten thousand steps. With the strong development of the industrial economy, the rhythm of life for future work will be greatly accelerated, the car will inevitably become a popular means of transport, car maintenance beauty services will become public daily consumption of content.
internal analysis: owners of car protection awareness increased year by year, year after year the amount of plastic chassis is the most powerful explanation. At present, economy cars, car prices in the shelf life of less than 80,000 yuan, chassis rust treatment for 1 year. Buick Regal to sail from the factory, anti-rust chassis, shelf life of six years. Dongfeng Nissan prices are 180,000 yuan more than in drier northern road conditions, the shelf life can be more than 100,000 kilometers, earlier in the more humid south road conditions, etc., rust chassis will be produced. There are a lot of cars at the factory, the chassis without care, so owners need to be more chassis care.
prevent metal fatigue phenomenon: I believe bought a new car owners have experienced, is driving a new car just landed the most solid feel most comfortable, feeling good, inner security full, fun to drive, in accordance with the model the passage of time and different, maybe a year maybe three years, will gradually feel some parts of the body seems to have loose feeling or noise generated, you can not find a specific reason, to open up and feel that the tires will not fall ? Will screws loose? Drive shaft will not cut off? That was not well enough to truly feel safe to come, change has been so fast that you would like to findBack to the car feeling, or allow you to live in fear, opened the car to particularly like always frightened, head of psychological feeling plush high speeds, in fact, this is the phenomenon of metal fatigue. Car is a dynamic tool, the body has been in a long-term state of shock, plus due to poor road conditions, lack of tires and suspension damping, the body showing metal fatigue phenomenon is a phenomenon often occurs in the general material, the causes of approximately because the long-term irregular force, vibration was generated, and the severity of the risk of this phenomenon is difficult to detect and predict, the best way is to prevent or limit the useful life of the material in advance. Therefore, when landing a new car through the necessary strengthening works to strengthen the underbody sheet metal, delay the emergence of the phenomenon of metal fatigue, make your car more than a few years to keep adolescence, called too.
9. Solutions
Generally for the solution armored vehicle chassis is divided into four parts:
1, the first is the need to make the chassis for armored automobiles assessment, an evaluation report.
Not all cars have to do the chassis armor, and the nature and quality requirements for different car owners, there are all kinds of different chassis armor to choose from. So before, we need to fully understand the thoughts and wishes of the owner, while the vehicle carried a comprehensive assessment report is consistent with doing the corresponding item chassis armor.
2, then the choice of products.
chassis armor brand on the market is very large, seemingly similar, are armored chassis, but the actual choice, the product is more and more functions there are many differences, there are 13 such excellent road series of car care products, as a professional car maintenance shop, 4S shop, should take effect on product performance and understanding of our customers recommend and choose the right product.
3, followed by construction operations and processes
is armored chassis construction plays a decisive role, a good product in the hands of operational staff do not understand technology, no matter how good were not much better. So the construction process must be strictly in accordance with the latest standards, cleanliness percentage to reach 99, the drying of 99.9 percentage, withWhen the weather with humidity in the air, under unsuitable conditions, and resolutely not illegal operations, so as not to cause adverse effects.
4, Inspection and sale protection.
Acceptance mainly from the following aspects,
⒈ Water resistance: is the resistance acting on the chassis armor water. Performance of armor chassis into water soaked for 24 hours, presence or absence of white chassis armor, loss of light blistering, loss and so on.
⒉ Salt spray resistance: is the resistance to salt water chassis armor. Analyzing can be used to test the performance of a protective coating. With 5 percent saline soaked for 24 hours, presence or absence of white chassis armor, loss of gloss, blistering, loss, rust and other phenomena
⒊ acid (base): the chassis armored resistance to organic solvent attack. With 3 percent sulfuric soaked for 24 hours, presence or absence of white chassis armor, loss of gloss, blistering, loss, rust and other phenomena
⒋ Gasoline resistance: 97 # gasoline soaked with 30 minutes play will be defective bubble shedding. After (detecting props)
acceptance, it is necessary to grant owner card quality assurance, meet the standards of quality assurance.
10, the difference
differ from sealed plastic chassis armor in the conventional sense, some businesses confuse the concept, instead of using sealed plastic chassis armor, damage the interests of consumers.
sealed plastic chassis is primarily to protect bare steel car chassis to prevent sand hitting, anti-corrosion, hit the sand listening to the voice of the chassis is still far from assured, in order to combat noise isolation gravel chassis issue, it is necessary be chassis armor. Professional chassis armor is a special kind of elastomeric gel material sprayed onto the vehicle chassis, the chassis and the hub portion of the noise is completely wrapped up, wait until the natural consolidation of the protective layer even chassis is formed, it can effectively reduce the impact of sand injury, to prevent rust and corrosion, in addition to having a sealed plastic armored chassis function, there is noise reduction effect, the chassis is formed on almost half a centimeter thick polyester material are mixed and a coating rubber. This coating has high elasticity, effectively weakening the sparkle stone direct hit on the noise emitted by listening to metal.
In addition to the different functions, both the composition and physical construction of the thickness are also different. Common plastic closures for the construction of 2 mm thickness. mainComponent is a polyester material and the polyester and rubber chassis armor material mixture formulation, construction thickness of 4 mm, more topical half a centimeter.
11, the main brand
the market’s main chassis armor brand or mostly foreign brands, are: the United States solid shield, 3M, Germany UNIKS, Germany Henkel, Wurth Honeywell, Ray-Ban, solid Patel, thanks to profit, LDH mine escape and so on.
Germany UNIKS, Henkel, LDH Ray escape: primarily rubbery material.
Most of the other type of aqueous or asphalt.
12, representative of the product
1, chassis rust plastic bituminous component. is the earliest anti-rust products, only saving grace is cheap, however, will be done in the future asphalt cracks, there are a lot of cracks, hidden in the crevices of the water will cause the “battery effect”, the car chassis the more severe corrosion, damage to the car will be even greater. Therefore, it is preferable not to use plastic chassis rust bituminous component chassis plate armor.
2, oil (solvent) chassis rust gum. Such products contain harmful toxic substances (used as the diluent solvent, such as toluene), harmful to the environment and harm human health. So in some strict environmental requirements of European and American countries have very few people use. Further, the adhesive layer oil (solvent) hard product, slightly curved at the glue line will crack, lack of flexibility, it is less effective in this regard chassis sound.
3, water-soluble glue chassis rust. Due to its diluent is water, non-toxic substances, so called water-soluble gum is environmentally friendly chassis rust chassis rust gum, mostly in Europe and America is now chosen such products. Soluble adhesion chassis rust plastic, preferably an elastic adhesive layer, remarkable sound insulation chassis, the chassis is made of armor material of choice.
4, the hybrid polymeric resin varnish. The first and second generation ofSecond-generation products are non-environmentally friendly, is gradually withdraw from the market, the third generation of environmentally friendly, but due to construction greatly influenced by temperature, humidity and time-consuming. The fourth generation of environmentally friendly fast-drying armored chassis with high water resistance, high flexibility, high corrosion resistance, high sound-absorbing noise reduction, and use their unique deep ionization four yuan grafting techniques in environmental protection on the basis of the four different performance the blend of polymer materials, it is not humidity, temperature control, greatly reducing the construction time, shorter than four times the conventional chassis armor curing time! Greatly facilitate the owners and construction workers.
The current market of high-end products mainly to foreign brands, the low-end market is mainly domestic products. According to the grade of the current market price armored chassis from three hundred dollars to several thousand dollars, the price of a few thousand dollars is also relatively better results, but does not rule out shoddy products. Opt net is recommended to choose a regular purchase channels when purchasing, pay attention to identification. The test method is a simple product of the transparencies coated with the above rust-proof paint, viewed against a bright place, and if the coating gap coarse particles larger than the coarse product description and low coverage, and easy to fall off.
13 Guidance
What kind of site is professional chassis armor armor? Professional car chassis armor chassis armor and poor and how to identify it? Mainly depends on the following aspects:
From an odor see cans, professional armored vehicle chassis with water and synthetic polymeric resins, weak odor; and inferior chassis armor asphalt, rubber, toluene , xylene and the like synthetic, unpleasant and pungent odor.
⑴ small amount of product on the paper, such as bituminous be yellow spots appear.
⑵ if they contain toxic solvent such as toluene, xylene and the like, the irritating odor, the product can be ignited with a flame.
2. Process of the construction, professional armored vehicle chassis having a high solids low viscosity characteristics, easy to apply, does not harm the builders and owners. Compared with professional chassis armor, armor inferior due chassis containing toluene, xylene and the like solvents, builders and owners of harmfulness.
3 from the deposition effect, the specialAll armored vehicle chassis industry, the use of polymer synthetic resins Technology, good toughness, good adhesion, high temperature can be done insoluble, low temperature does not crack, rust with a strong, impact-resistant and soundproof function. The poor quality of anti-rust chassis armor only simple and easy to fall off (summer high temperature and easy to melt, stick things; winter at low temperatures is easy to crack, easy to fall off).
may also be employed the following simple way:
a look: See surface concavity, a convex uniform and large, the impact resistance ability noise.
two pinch: pinch force model or make of car chassis, dents can be quickly restored, you have the ability to resist the impact of gravel.
three-fold: bend model from a different perspective, to see whether it will break, which is determined flexibility and adhesion.
four sun: to do a good job on the car model or sun exposure, to see whether it softens to become tacky.
