The rubber member, i.e. products made of rubber parts. Rubber has good performance flexibility, sealing and insulation properties, in many industries have wide applications, as ldquo; reinforced steel frame rdquo; cars are naturally inseparable from its use. .
One type of automotive rubber member
according to their different functions, automotive rubber parts are the following:
1, water pipes, tubing categories: Engine Cooling System cold water pipe, the engine fuel system bribery inlet pipe, tubing and return tubing in the power steering system and the like;
2. Shock absorption: mainly used in automobile chassis, engines;
3, seals, strips classes: automotive various sealed, waterproof strips, such as doors, windows, and other parts of the front windshield;
4, dustproof cover: a steering system dust cover, reduce wear on the dust debris member, extending its life;
2. Rubber link knowledge
First, the rubber properties
First, the biggest feature of the rubber is very small elastic modulus, and high elongation.
Next, it has a very good corrosion resistance, and air permeability of various chemical mediators and electrically insulating properties. Some more special synthetic rubber with good oil resistance and temperature resistance, resistance to fatty oil, lubricating oil, hydraulic oil, fuel oil, and a swelling solvent; cold may be as low as -80 deg.] C to -60 ℃, heat may be 180 [deg.] C to as high as + 350 + deg.] C.
Flexing rubber also resistant to various bending deformation, because of the small hysteresis loss. It characterized in that the third rubber material and it can be used with a variety of blending, compounding, whereby modified to give a good overall performance.
The basic properties of the rubber, making it excellent damping, the seal industry, flexing, wear, corrosion, and insulating materials such as an adhesive.
Second, the classification of rubber
1, according to the morphology of the rubber, the rubber can be divided into a solid rubber (also known as dry rubber), rubber emulsion (abbreviated latex) , liquid rubber, and rubber powder four categories.
2, according to sources of raw materials and methods, can be divided into natural rubber and synthetic rubber into two categories. Wherein the consumption of 1/3 natural rubber, synthetic rubber consumption 2/3.
3, according to the properties and uses of rubber, in addition to natural rubber, synthetic rubber, synthetic rubber can be divided into general, semi-universal synthetic rubber, synthetic rubber and dedicated special synthetic rubber.
4. The physical form of rubber, rubberIt can be divided into soft and hard plastic, green plastic mix and the like.
5. The type of rubber and the crosslinked form, in industrial use, and the rubber can be classified as follows.
by a class of heat-resistant and oil and other functions are divided into: general rubber, heat-resistant rubber, oil resistant rubber and rubber weathering, chemical resistance, special media such as rubber.
Third, the rubber seal products
tape, glue row, rubber, O-ring, a rectangular ring, round plastic beads, plastic beads diamond, square pad , fuel gauge pad, double seals, flanges, block, flange, pad, flat O, plastic buckets, continued long block and the like.
