Framework material of rubber pipe

时间:2021-09-02浏览次数:319

Rubber pipes are mainly used to transport various gases, liquids, viscous fluids or solid particles under positive pressure or negative pressure. They are widely used in industry, agriculture, energy, transportation and other fields. In the process of practical application, the main role of skeleton data in rubber pipes is to improve the strength and stiffness of rubber pipes. The detailed role of skeleton data varies with the structure of rubber pipes. What are the commonly used skeleton data of rubber pipes? What different roles have they played?

The commonly used skeleton data of rubber pipes can be divided into two categories: wire rod and fabric. Wire rod also includes fiber wire rod and metal wire rod, and fabric includes canvas and cord fabric.

1. Fiber wire

In practical consumption, cotton thread and chemical fiber thread are commonly used for rubber pipes. Chemical fiber line also includes rayon, vinylon line, nylon line, polyester line, etc; Chemical fiber line has the characteristics of high strength and chemical corrosion resistance, which is more and more widely used in rubber hoses.

2. Metal wire

Metal wires commonly used for rubber pipes include steel wire, steel wire rope, ordinary carbon steel wire, iron wire and stainless steel wire. Stainless steel wire is not easy to rust, and it is mainly used for rubber hoses in contact with corrosive media, but the price is relatively high, and it is usually used only in the rubber hose skeleton data with special requirements. Some rubber hoses also use copper, aluminum and other static conductive metal wires. In practical consumption, polyamide, polyethylene, polypropylene or rigid polyvinyl chloride can also be used to replace metal wires for rubber pipes, which have light texture, corrosion resistance and good compression flat deformation performance.

3. Canvas frame

Canvas is a commonly used framework material in the consumption of rubber tubes, which has many ways such as plain, twill and square, among which plain is more common. Apple canvas is 90 °, with a high strength density ratio, and the fabric toughness is higher than that of canvas with twill 2ylyy615 structure. In practical consumption, there are two types of canvas commonly used for rubber tubes: cotton canvas and chemical fiber canvas. Chemical fiber canvas also includes vinylon, vinylon cotton blend, nylon, polyester, etc., of which vinylon and vinylon cotton blend are more common.

4. Cord fabric frame

The cord fabric commonly used in rubber tube consumption is crisscrossed by warp (cord) and weft (yarn). The function of warp is to provide strength, and weft is only used to connect and adhere to the average arrangement of warp in cord fabric. In real purchase, rubber tubes are commonly used in cotton cord fabric, clay dragon cord fabric, viscose cord fabric, polyester cord fabric and vinylon cord fabric.

The rubber pipe needs to select appropriate rubber and plastic materials according to the application site and physical property needs, including natural rubber, styrene butadiene rubber, CIS butadiene rubber, nitrile rubber, butyl rubber, ethylene propylene rubber, silicone fluororubber, reclaimed rubber, polyethylene, polyvinyl chloride, chlorinated polyethylene, polytetrafluoroethylene, etc. some rubber and plastic materials can be used alone, or two or more materials can be used together. Select appropriate skeleton data to further improve the comprehensive index of rubber pipe.
