High quality factory, focus on high-end seals! Fast shipping!

A gasket is a material or combination of materials clamped between two separate joints (flanges) and serves to maintain a seal between the two joints for a predetermined service life. The gasket must be able to seal the joint surfaces and ensure that the sealing medium is impermeable and non-corrosive, and can withstand temperature and pressure, etc.

Q: How to improve the mobility of rubber material: Fully plasticated rubber use, reduce the Mooney viscosity, improve its ductility.

Q: What problems need to pay attention to when inflating the pipe?: Pipe water blocking airbag, closed water test, sewage pipe matters are different, big air sac, small sac also have differences, in terms of sewage pipes, we need to pay attention to the following points:1, because the airbag is rubber products, so afraid of scratching, when receiving airbags, we must first test gas test to see if there are broken places. Repair and replace in time.2, carefully check instructions, rated pressure, etc..3, in the ground to connect three pressure gauge, slowly filling some gas, slowly into the pipeline.4, clean up the pipeline wall, no burr, punctured balloon.5, carefully checking the pressure meter, slow inflation, do not look at the gas, to avoid pressure gauge not timely response and the consequences of explosive charge. When the work pressure is up, stop inflating and never exceed the pressure.6. The large air bag has a handle on it and prevents it from running.

Q: Excuse me, is PU one kind of silicone? Or what is the connection between the two?: Silica gel (Silica gel; Silica) alias: silicone rubber is a highly active adsorption material, belongs to amorphous material, its chemical formula is mSiO2. NH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemical stability, in addition to strong alkali and hydrofluoric acid, do not react with any substance. Different types of silica gel have different microporous structures because of their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics which are difficult to be replaced by other similar materials: high adsorption properties, good thermal stability, stable chemical properties, high mechanical strength, etc.. According to the size of the pore size, silica gel is divided into large pore silica gel, coarse pore silica gel, B type silica gel and pore silica gel.

Q: How are rubber wires processed?: [summary] the main raw material is rubber, rubber products with various agents, as well as the fiber and metal skeleton material, the basic production process of rubber products including plastication, mixing, calendering, extrusion, molding, curing 6 basic processes.The processing process of rubber is mainly to solve the process of plastic and elastic contradictions, through various means of processing, the elastic rubber has become the plastic rubber, adding various in the preparation of semi-finished products, and then through the vulcanization is has semi-finished plastic and rubber products into high elasticity and good mechanical performance the.

Q: How does the rubber part of the watch become yellow?: It is mainly divided into two kinds of natural rubber and synthetic rubber. Natural rubber is made from rubber, rubber and grass. Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life. It has a wide range of uses. [1] can also be divided into rubber with natural rubber, general rubber, styrene butadiene rubber, nitrile rubber, silicone rubber, butadiene rubber, butyl rubber, EPDM rubber, chloroprene rubber types.

Q: Aging of rubber parts for automobiles: Due to the comprehensive effect of various internal and external factors, rubber products will deteriorate the chemical properties and mechanical properties of this kind of phenomenon is realized by rubber aging, cracking, sticking, hardening, powder, mold. Shute rubber reminder, especially the rubber parts on the vehicle, due to the complex use of the environment, aging accelerated more obvious.

Q: What plastic rubber will not be subjected to oil (such as transformer oil) by quality (e.g., aging, dissolution)?: Generally, aging and dissolution occur. If you want to make the structure, you can choose XF POM C13031 Ticona of the company. This is the company specializing in the development of temperature resistance, oil (especially gasoline, diesel) products.

Q: How to clean rubber products?: Rubber products are made of rubber raw materials and made from mixing rubber and mixed rubber as raw materials. When the rubber is mixed, the formula is designed according to the characteristics of the required rubber products, and the hardness of the products is determined. The product is made and molded by rubber flat vulcanizing machine. Finally, the product is processed by flying edge, and the surface of the product is treated smoothly without burrs.

Q: How to distinguish between silicone hose and rubber tube by appearance?: Smell, silicone no flavor, rubber flavor, silicone general flexibility better, rubber mechanical better
