1, the coolant composition recommended application
by the coolant water, antifreeze, three parts of additives, can be divided into different components according antifreeze alcohol type, glycerin type, glycol type and other types of coolant. Coolant alcohol is ethanol (commonly known as alcohol) for antifreeze, cheap, good fluidity, simple preparation process, but low boiling point, evaporation loss is easy, easy to increase the freezing point, flammable, is now gradually being phased out; glycerol coolant high boiling point, low volatility, easy to fire, toxic, corrosive small, but poor freezing point reducing effect, high cost, expensive, difficult for the user to accept, the Nordic countries still using only a few; glycol type ethylene glycol coolant is used as antifreeze, and add a small amount of anti-foaming, anti-corrosion additives formulated integrated. Because ethylene glycol is soluble in water, may be arbitrarily formulated into various cooling liquid freezing, the minimum freezing point up to -68 deg.] C, such a cooling fluid having a high boiling point, low foaming tendencies and good viscosity-temperature properties, corrosion and scale etc., is an ideal coolant, the coolant and the current engine used abroad markets sold almost all of this type of glycol coolant. Compressor refrigerant is sometimes called coolant.
2, four function
In order to prevent the car after the winter season, coolant tank caused by ice, bursting engine block, coolant required freezing point lower than the lowest temperature in the region of about 10 ℃, to Preparation of sudden change in weather. 2. Corrosion
The cooling system radiator, waterThe pump, the cylinder block and cylinder head, the distributor and other components are made of steel, cast iron, brass, copper, aluminum, solder, weld metal, due to the different electrode potentials of different metals, galvanic corrosion easily occurs under the action of the electrolyte ; acidic products while the cooling liquid glycols substance formed after decomposition of the fuel combustion exhaust gas may also be an acidic trailing penetrate into the cooling system, the cooling system to promote corrosion. Corrosion can cause the radiator tank the cooling system of the water chamber, nozzle spacer, a cooling pipe, pipe joint and exhaust tank failure, while the corrosion products clog the pipe, causing the engine to overheat or paralysis; if corrosion perforation, the cooling fluid into the combustion chamber or crankcase can cause serious damage, because when the cooling or water mixed with oil considerate to produce oil and gum impair lubrication, such valves, hydraulic valves and the push rod piston bond. Thus the coolant are certain amount of anti-corrosion additives, the cooling system to prevent corrosion. 3. Calc
Cooling fluid should be as little as possible to reduce the generation of scale in a loop, to prevent blockage of the circulation duct, affect the cooling function of the cooling system. As described above, in the selection, add coolant should be carefully. Firstly, as the case may be to choose the appropriate ratio of 
national standard coolant, usually having a boiling point exceeds 105 deg.] C, 100 deg.] C than the boiling point of water, the coolant can withstand higher temperatures without boiling (boil), to a certain extent to meet the cooling needs high heat load of the engine.
3 Characteristics
Cooling was cooled parts, automotive heat vehicle before use for automotive air-conditioning seat back supplies, steering wheel, etc.
1, the key components of this product , dry ice (solid CO2), and environmentally friendly, non-toxic, non-corrosive, non-polluting characteristics
2, light refined fragrance, pleasant and comfortable
3, rapid heating after spraying, evaporation heat absorption mat rapid cooling effect on the surface, you can immediately cooled to 40 degrees
4, the seat temperature is low or the spray caused by uneven white ice crystals, wait a moment, ice may evaporate
4, Note
Proper use coolant can play to corrosion, cavitation leakage, anti-boil radiator, the role of anti-freeze and water scale, of the cooling system in the best working condition, to ensure the normal engine operating temperature. If not pay attention, it will seriously affect the normal operation of the engine performance and life, and therefore, special attention should be precautions used coolant
In use
1, coolant is used to adhere perennial for the conventional engine, to ensure the normal operation of the engine coolant temperature value 80 ℃ ~ 90 ℃, but for the electronically controlled engine, due to its high speed, high compression ratio and high power working characteristics, mechanical and thermal loads load is large, higher frictional heat which requires cooling liquid normal operating temperature has been increased to 95 ℃ ~ 105 ℃. This traditional form of engine cooling water and the people “normal temperature” different points of view, people need to know the concept of change. And pay attention to the continuity of coolant used, the kind used in the winter just want to view is wrong, just know that the coolant antifreeze function, while ignoring the anti-corrosion coolant, anti-boil, scale and so on.
2, the correct selection When selecting the cooling liquid, which is lower than the freezing point of minimum temperature of about 10 ℃. At present, the type of coolant on the auto parts market and more, “Coolant” is really just “antifreeze”, added color mixing alcohol and water after using mostly made therein without any coolant additive should have a boiling point at 90 about ℃, corrosive, easily lead to overheating of the engine. A method to distinguish the authenticity of the cooling liquid
high coolant striking color, clear and transparent, and no smell; beaker was heated coolant, a thermometer measuring the boiling point, a boiling point above 100 ℃ it is authentic, those having a boiling point less than 100 deg.] C to counterfeit goods. ?
5, will beReplacement of the
changes the engine coolant based on mileage or duration, since it is difficult to determine its degree of deterioration visually. If the coolant does not change its inherent rust reduced quality, a radiator, pipes, hoses, etc. will be damaged.
6, introduced species
to ensure that the coolant is water-cooled engine work necessary working medium.
When the engine overheating, charging efficiency will lead to reduced engine power down; pre-ignition so that knocking tends to increase, to premature failure of parts; deterioration of lubrication between the moving parts, increased wear and so on.
When the engine is too cold, it will lead to a difference into the mixed gas cylinder quality, decreased engine power, increased fuel consumption; acidic corrosive components in combustion products; unburned fuel dilution and flushing the surface of the moving member lubricant film, it increased wear and tear. This requires that the user must understand the performance characteristics of the coolant, to master the proper use of coolant.
by the coolant water, antifreeze, additive 3 parts, can be divided into different components according antifreeze alcohol type, glycerin type, and other types of glycol type coolant. Coolant-alcohol
Coolant alcohol is ethanol as antifreeze, cheap, good fluidity, simple preparation process, but a lower boiling point, the loss of volatile, easy to increase the freezing point, easy to fuel, is now being phased out. Coolant glycerol
Glycerol Coolant high boiling point, low volatility, easy to fire, toxic, corrosive small, but poor freezing point reducing effect, high cost, expensive, difficult for the user to accept only a few Nordic countries are still in use. Glycol Coolant
Glycol Coolant is used as antifreeze ethylene glycol and a small amount of anti-foaming, anti-corrosion additives formulated integrated. Because ethylene glycol is soluble in water, may be arbitrarily formulated into various cooling liquid freezing, the minimum freezing point up to -68 deg.] C, such a cooling fluid having a high boiling point, low foaming tendencies and good viscosity-temperature properties, corrosion and scale etc., is an ideal coolantCurrent coolant and sold on the market and abroad use almost all engine coolant glycol type. ?
7, recommended application
is particularly applicable to wind turbine cooling system can also be used a variety of commercial and other stationary generator set, the engine cooling system for industrial use .
