Rubber Hose The Structure Is Usually Divided Aug 25, 2017

Rubber Hose The structure is usually divided

Used to transport gas, liquid, slurry or granular material of a class of tubular rubber products. The hose is made up of inner and outer layers and skeleton layers. The material of the skeleton layer can be made of cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire and so on. Rubber hose is made of chloroprene rubber, nitrile rubber, acid and alkali resistant, high temperature resistant hose adopts ethylene propylene rubber, fluorine rubber or silicone rubber, etc. It is made of natural rubber, styrene butadiene rubber or butadiene rubber.

Many types of hose, unified naming method is the material, structure, use the different name, the product called: material + structure (process) + use + hose. For example: cotton thread weaving oil hose; wire wound pressure hose.

Hose structure is usually divided into: inner layer, outer layer and skeleton layer (or middle layer). The inner layer directly to bear the transmission medium wear and erosion; outer rubber layer to protect the hose from the external environment

Hose according to the type of product is divided into high pressure and low pressure hose, the process is: the purchase of qualified raw materials and admission testing, the use of open mixing machine for plastic to break the original molecular structure, change its plastic properties, according to the formula Various types of fillers, curing agent, stabilizer, vulcanization accelerator and other mixing, and then placed in a cool place for 24 hours, into the production area and then to warm the production in order to facilitate the need to be divided into the inner plastic, plastic , The outer layer of plastic, the inner layer of semi-vulcanization, to improve their hardness and machinability, and then sent to the weaving area to join the middle layer of woven steel wire layer or nylon layer, according to the number of production and processing layers, Vulcanization tank for rubber vulcanization process, so that it is fundamentally fused together to stabilize the internal links of the rubber. Products from the workshop after the test press into the workshop, after passing the packaging and sent to the Treasury, keep the label and paste the storage, do a good job of time and quantity of storage records. Hose forming method according to the use of die or not, can be divided into a core method (including soft core and hard core method), coreless method. A core method refers to the hose in the hard core or soft core on the shape, coreless method is the skeleton layer and the outer layer directly in the extrusion of the inner hose on the shape. In order to ensure that the hose in the vulcanization process in the pressure state, the hose after forming the package of water cloth (width of about 10cm damp cloth), rope or lead, and then vulcanization. The vulcanization can be carried out by direct steam heating or continuous vulcanization.
