Inventory of Hose Knowledge

Hose is a kind of tubular rubber products used to transport gas, liquid and mud-like substances. It consists of inner rubber layer, outer rubber layer and interlayer. The material of interlayer can be filled with cotton thread, cord, steel wire and so on.

The inner and outer rubber layers of general rubber hoses are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant rubber hoses are made of neoprene and nitrile rubber; acid-base and high-temperature resistant rubber hoses are made of ethylene-propylene rubber, fluorine rubber, or silicone rubber. The inner rubber layer of the hose directly bears the wear and erosion of the conveyed medium and prevents its leakage; the outer rubber layer protects the interlayer from external damage and erosion; the interlayer is the pressure layer of the hose and is a very important link. Partial pressure and weight. The working pressure of the hose depends on the material and structure of the sandwich, so the quality of the hose has a lot to do with the sandwich.

The basic process of hose production is compounding rubber processing, cord (cord cord) and canvas processing, hose molding, vulcanization, etc. With different structures and different interlayers, the processing methods of the interlayers and the hose forming equipment are different.

Because the full rubber hose does not contain interlayers, you only need to use an extruder to extrude the hoses. Cloth hoses require a forming machine that wraps the tape on the inner rubber layer. Steel wire sandwich hoses need to be wound with a metal spiral before forming. Inner rubber; Wire Braided Rubber Hose requires special fabric knitting or winding machine; Knitting hose requires knitting machine.

Hydraulic Hose

For the application of hoses, the industry is in short supply. The first choice is to use the Hydraulic Hose with the steel wire is the most commonly used. In view of good pressure and oil resistance, it is used in equipment connection, construction machinery, hydraulic pillars, etc. The maximum pressure reaches 70Mpa.

The range of incoming water for rubber hoses with cloth is wider, and industrial water, mud, hydraulic oil, emulsified oil, hot water tail steam can be used. Large-caliber hoses, 6 layers of cords, and a layer of spiral steel wire. Under negative pressure, the products that are exported more are steel braided hoses, ordinary hoses, etc., and high-tech automotive hoses, such as hoses less. The proportion of chemical fiber winding pipe, braided pipe, knitted pipe, steel wire braided pipe, wound pipe and resin hose in the hose exceeds 60%, which is also close to the international advanced level. Because the product structure is in line with international standards, it is conducive to the export of Chinese rubber tube products.
