With the continuous development of science and technology, now almost every family has a car of their own, so do you know what kind of hose cars need to use?
Small make up now with you to understand.
One, automobile air conditioning hose
The inner rubber layer of automobile air conditioning rubber hose is EPDM
This water pipe has the advantages of low permeability, high temperature resistance, uv protection, etc., can be used in the environment of -40~140℃, or even used in the high temperature environment of 160℃, the automobile air conditioning hose to the technical requirements of the hose products are very high, is the use of the hose key technical indicators for low permeability.
Two, the automobile cooling water pipe
The main function of the automobile cooling system is to let some heat absorbed by the heated parts be released in time to ensure the engine works at the most suitable temperature.
Cooling water hose is a gentle pipe connecting the car engine and radiator. Its main function is to transfer cooling fluid and dissipate heat to ensure the safe and normal operation of the engine.
At present, the working temperature of cooling water hose in China can reach 125℃, which is produced by EPDM. The hose consists of three layers: lining layer (EPDM), reinforcing layer and outer layer (EPDM).
Three, automobile brake hose
Automobile brake hose must have good aging resistance and moisture permeability in addition to brake fluid resistance.
In the past, the material used in automobile brake hose was mainly styrene-butadiene rubber.
Recently, due to the emergence of maintenance free cars, brake fluid working environment temperature increase and the use of high boiling point brake fluid, epdm or epdm/butyl rubber may replace styrene butadiene rubber, become a new favorite automotive hose.
Parlmu EPDM pipe adopt imported EPDM rubber, mainly because it has a good wear resistance, anti-aging, acid and alkali corrosion resistance, high and low temperature resistance, air tightness is good, in the 230 ℃ heating steam, nearly 100 h after appearance no change;
The rubber is mainly used to transport water, air, antifreeze, steam and weak acid and alkali liquid in automobile, mechanical water tank, engine and other parts, the quality can be guaranteed.
