Processing method and molding process of rubber plate

Rubber slab; Rubber sheet is a sheet product with a certain thickness and a large area, which is made of rubber as the main material (can contain fabric, metal sheet and other reinforcing materials) and vulcanized. The rubber plate has high hardness and general physical and mechanical properties. It can work in the air with low pressure and temperature of 20 °~+140 ℃. The rubber plate is made of rubber compound by calendering, laminating or extrusion molding, vulcanizing with a flat vulcanizer or continuous vulcanizing with a drum vulcanizer. Color: black, gray, green, blue, red, etc. It is widely used in industrial and mining enterprises, transportation departments and building floors. It is used as sealing rubber ring, rubber pad, door and window seal, and laying workbench and floor.

Warmly congratulate the official website of "Hebei Hengda Sealing Materials Co., Ltd." on its official launch!

Hebei Hengda Sealing Material Co., Ltd., founded in 1987, is a professional sealing material manufacturer integrating scientific research, production and sales, and an advanced director unit of China Friction Sealing Material Association. Located in Shucheng Industrial Development Zone, Hejian City, the company has become a group enterprise with fixed assets of nearly 100 million yuan. With strong technical strength, it is a manufacturer that participated in drafting and formulating the national standard for the test method of oil-resistant asbestos rubber plate, and has successively developed anti-corrosion asbestos rubber plate and oil-resistant composite sealing liner plate, which have respectively won the national patent certificate for utility model products. The company cooperated with Shanghai East China University of Science and Technology to establish a joint sealing laboratory. Sanda brand won the title of "Famous Trademark of Hebei Province" in 2007 and 2018 by virtue of its good reputation. At the same time, the company produced various asbestos-free, asbestos-free and metal spiral wound gaskets, which were used together with relevant manufacturers at home and abroad. The company has passed the 1S09001 quality system certification and has the right to import and export itself. The export countries include South Korea, Malaysia, Vietnam, Indonesia, Pakistan, Thailand, Nigeria and other countries and regions, and has established stable cooperative relations with many foreign merchants.

What is the difference between asbestos and non-asbestos board sealing materials

Asbestos and non-asbestos sealing materials, asbestos sealing materials are more resistant to high temperature than non-asbestos sealing materials. The main components of asbestos sealing materials are asbestos, filler and rubber, during which the temperature resistance of asbestos and filler is very high; Most asbestos-free sealing materials are mainly composed of mineral fiber, organic fiber, filler and rubber. During this period, the temperature resistance of organic fiber is usually at 200 ℃, and the current temperature resistance of asbestos gasket has reached 1000 ℃.

The technical information of the technical formula of the fire-proof bag and fire-proof bag can let you know more

The product can be made into various shapes of firewalls and fireproof layers according to different requirements of users, and can also block the holes that need to be fireproof. In case of fire, the material of the fireproof bag will expand under heat and form a honeycomb block, effectively controlling the fire within the local range. The fireproof bag is used as the partition instead of the refractory brick, slag wool, ceramic wool and other materials used in the past. Compared with them, the fireproof bag has significant heat insulation effect.

Correct use of fire clay

Rub the organic plugging material evenly and insert it into the hole. The organic plugging material will be hard when the temperature is low. At this time, the plugging material can be heated in warm water at about 50 ℃ and can be used when it is slightly soft. This organic plugging material is generally used in combination with XXMF-3 fireproof plugging material (fire retardant bag). When the plugging thickness is 150 mm, the fire resistance limit is greater than or equal to 3 hours.

What are the uses of fire clay

This material is mainly used for plugging the holes of wires and cables to prevent the fire of wires and cables from spreading from the holes to the adjacent rooms and reduce fire losses. It has the functions of smoke prevention, fire prevention and dust prevention to avoid the expansion of accidents. Therefore, the plugging material is widely used for plugging vertical and horizontal wires and cables through holes in power plants, industrial and mining enterprises, high-rise buildings, shipbuilding power, post and telecommunications, substations, metallurgy and other system projects.
