Raw materials used in rubber pipe production

Rubber pipes are used to transport various gas, liquid, slurry or granular materials in production and life, generally consisting of inner and outer rubber layers and skeleton layers; the raw materials used in the production of rubber pipes have a great influence on the performance and service life of hoses; In actual production, what raw materials will be used in rubber hoses, and what are the specific effects? What are the common hose products that are processed from 1JLYY822?

1. Raw materials commonly used in rubber pipe production

1 Rubber: Rubber is the main material in the production of rubber tubes, natural rubber, styrene butadiene rubber, neoprene, nitrile rubber, ethylene propylene rubber, butyl rubber, isoprene rubber and various types of latex reclaimed rubber, tire reclaimed rubber, Butyl reclaimed rubber, nitrile reclaimed rubber and EPDM reclaimed rubber can be used to produce rubber hoses. The combination of reclaimed rubber and corresponding types of raw rubber can ensure the performance of rubber hoses and reduce the cost of raw materials. At present, there are silicone rubber hoses, urethane rubber hoses, and chlorosulfonated polyethylene hoses.

2Plastic: Compared with rubber, the plastic polymerized by polyaddition or polycondensation reaction is impact-resistant and easy to form. It can be used together with rubber to further improve the processing performance of the rubber compound. Therefore, many rubber tubes are used in the production process. In this way, polyvinyl chloride, chlorinated polyethylene, polyethylene, polyamide, and thermoplastic elastomer can be used in the production of rubber pipes as raw materials.

3 fiber: fiber material is generally used as a skeleton material in the production of rubber products. It has high strength, small elongation, uniform twist and good thermal stability. Compared with the cloth hose, the pipe body is lighter, with higher bearing strength and bending resistance. The performance is better; the fiber material is easy to use and simple to process, and is an ideal skeleton material in the production of rubber tubes. At present, the fiber materials commonly used in the rubber tube production process include cotton thread, viscose thread, vinylon thread, nylon thread, polyester thread, and aramid thread.

4 steel wire: steel wire material has high strength, good toughness and small extension. It can improve the anti-pulsation fatigue performance of rubber tube in the production of high-pressure hose. High-strength steel wire is a commonly used reinforcing material in high-pressure and ultra-high pressure hoses with braided or wound structure; Wire rope, general carbon steel wire, iron wire and stainless steel wire may also be used in the production process. The carbon steel wire can be used in the suction hose, and the wire can be used in the production of the cloth hose or the suction hose.

Generally, oil-resistant hoses are mostly made of nitrile rubber, nitrile reclaimed rubber, neoprene, etc. Long-term exposure to air hoses can use EPDM or EPDM reclaimed rubber. High-temperature steam hoses use butyl rubber or butyl reclaimed rubber. The most suitable and so on. The selection of suitable rubber materials and other reinforcing materials in the production process ensures that the products can be used for a long time and the production cost can be minimized.
