The automobile is now the most important transportation tool in people's daily life. The automobile water pipe is an important rubber component in the automobile, including the radiator hose, the air-conditioning hose, the sunroof drainage pipe, etc. A large part of which is the use of EPDM rubber. produced. However, the price of EPDM rubber is quite high, coupled with fierce competition in the market. If blindly using EPDM rubber to produce automobile water pipes is difficult to win in market competition, especially among small and medium-sized manufacturers; this time, Sanyuanyi C reclaimed rubber has become the best raw material for the production of rubber water pipes instead of EPDM.
EPDM rubber is composed of saturated hydrocarbons in the main chain of the rubber molecule. Only the unsaturated double bond is contained in the side chain. Therefore, it is excellent in aging resistance, heat resistance and ozone resistance and can be used for the production of automotive hoses. Various car parts inside. The main raw materials of EPDM reclaimed rubber are EPDM scrap rubber and waste EPDM rubber products processed through a special process, which retains most of the molecular structure of EPDM rubber and possesses EPDM rubber. The performance characteristics; Processing and much lower than the original EPDM rubber, used to replace the original EPDM rubber pipe production of automotive water can not only maintain the same physical properties, but also can significantly reduce the cost of raw materials.
Different parts of the automobile water pipes have different performance requirements for the EPDM reclaimed rubber, so the proportion of the EPDM reclaimed rubber used is also different. Automotive radiator hose is used for automotive engine and radiator system hoses, should have good high temperature performance; automotive air conditioning hose is used to connect the car air conditioning system and other refrigeration system hose, should have a reliable pressure capacity, Excellent resistance to high and low temperature performance, corrosion resistance; automobile sunroof drain pipe is one of the accessories of the auto sunroof, the role is to discharge the waste water in the sunroof drainage tank, so the raw material for production sunroof drain pipe should have good resistance to high and low temperature, gas Tightness, watertightness and wear resistance.
It can be seen that although the water pipes on the car can use EPDM reclaimed rubber, there is a certain difference in the performance of rubber pipes in different parts. The manufacturer of the automobile pipe manufacturer must select the appropriate EPDM reclaimed rubber according to the demand. The indicator's product, reasonable adjustment of the proportion of EPDM recycled rubber, to ensure the use of automotive water pipe performance and service life under the premise of minimizing production costs.
