The hose is widely used and industrially produced because of its natural advantages. With the needs of all walks of life, the types of hoses are constantly enriched. The hose market in the automotive industry has always attracted attention. Although there are not many types, it is a representative of the hose industry.
1 Air conditioning hose
In the past two years, my country’s automotive air conditioning hoses have developed rapidly, and the number of companies producing and developing new types of hoses has gradually increased. The development of high-quality air-conditioning hoses needs to solve two technical problems. The first is the pollution of the air-conditioning hose, and the second is the leakage of the fluorine-free hose. Protecting the environment starts with small things, and optimizing our automotive air conditioning hoses is everyone’s responsibility.
2 Radiator hose
High-grade EPDM rubber is used as the main material of the radiator hose, a special synthetic fiber knitted reinforced structure is selected, and the domestic first cold feed extrusion technology and a new coreless preform sleeve mold naked vulcanization process are used to successfully manufacture It produces automobile radiator hoses with technical indicators such as breaking strength, ozone resistance, and adhesion strength that meet international standards.
3 Fuel hose
The inner rubber layer is composed of fluorine rubber and chlorohydrin rubber, and the outer rubber layer is chlorohydrin rubber. The difference is that the reinforcement layer uses aramid fiber. According to related reports, domestically produced automotive composite fuel hoses have been used in Santana, Audi, Jetta, Fukang, POL0 and other vehicles.
4 Brake hose
The brake hose is an important component that has very strict quality requirements and is related to vehicle and personal safety. In addition to being resistant to brake fluid, brake hoses must also have good aging resistance and moisture permeability.
5 Power steering hose
Power steering hoses are more stringent in automotive hoses. There are two specific requirements. One is good heat resistance, and the other is to prevent corrosion of oily substances. This has caused some contradictions. The steering hose using fluororubber has good heat resistance, but because the fluororubber tube easily reacts with certain additives in the oil, its application is limited. Therefore, many car enthusiasts often have strict requirements on the steering hose of the car.
6 Turbocharger hose
Turbocharger hoses are mainly suitable for racing cars and sports cars. In recent years, due to consumer demand, the development of ordinary cars has begun. my country’s turbocharger hoses are still in the research and development stage and have a good development momentum.
