1.Description of Gasket :
Ginseal Spiral-wound gaskets comprise a mix of metallic and filler ma- terial. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flex- ible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal.
2.Features of Gasket :
• Perfect sealing performance.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.
• Heat treatment industry for furnace parts, fans, tube hangers, and baskets and trays to hold small parts.
• Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide.
• Food processing industry.
• Hot acetic and citric etc.

4.Specifications of the Gasket:
1.A good compression ratio and elasticity.
2.With plastic appropriate, after pressing can adapt to the sealing surface and sealing surface uneven fill the gap, to ensure good sealing performance with the temperature and pressure in the system of alternating case.
3.With excellent corrosion resistance, not to be damaged in some extreme medium, does not have the expansion and contraction.
4.Under the condition of high temperature softening, does not creep; under the condition of low temperature hardening, does not shrink.
5.Have sufficient strength, when external load conditions, not be crushed; at high temperature, not blown out.

- Q: When rubber products are hardened, what methods soften?
- The rubber is softened by soaking in the solvent, but it will damage the original physical and chemical properties of rubber!
- Q: What kind of rubber coated aluminum alloy (metal) better
- This is still a problem, the metal is with the rubber, and what rubber can wrap metal, regardless of which kind of metal can and rubber good bonding, the key is what your customers need to use what kind of rubber
- Q: Why do rubber products Blister?
- Foaming reasons of rubber products:1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, the vulcanizing pressure is insufficient, the detained gas and sulfur volatile matter can not be discharged in time.3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the rubber material in the steam, air free precipitation.
- Q: Is vulcanized sole good or rubber sole is good?
- Rubber base, vulcanized bottom are basically the same, rubber vulcanization is only the process of shoe-making, rubber is the bottom of the way vulcanized and uppers together, it is more difficult to open
- Q: How to distinguish between good and bad silicone rubber gasket?
- Hardness and elongation stress reflect the rigid (stiffness) index of rubber material, and they are the necessary force for silica gel products to produce certain deformation. It is also a way to distinguish the quality of silica gel products.
- Q: Comparison of physical properties of HNBR rubber material with other rubber materials
- HNBR has a high temperature resistance of 130~180 degrees, cold resistance of -55 ~ -38 degrees, and good mechanical properties, compared with other polymers, can meet the requirements of the automotive industry. HNBR with ZnO/ methacrylate (MAA) can be used to make V-belt, triangular V-belt, multi base rubber, vibration isolator and so on. It can also prepare sealing ring, sealing element, heat resisting tube and so on. In oil drilling, rubber products are required to withstand high temperature, high pressure, acid, amines, H2S, CO2, CH4 and other tests of steam. The products prepared by HNBR can be acid resistant, oil resistant and solvent resistant. With the ZnO/MAA HNBR reinforcement can be used for the production of drilling mud pump piston and protection box. In addition, the beating method HNBR can be used as a sealing washer washer made of paper oil industry and automobile industry. HNBR heat and radiation resistance properties than silicon rubber, fluorine rubber, poly four vinyl chloride is better, suitable for all kinds of rubber seals for power station, is also used as a hydraulic pipe, hydraulic seals, power station for cable sheath, can also be used for printing and fabric roller, weapons components and aerospace seals, cover, fuel capsule; HNBR latex can be used as a surface coating (painting), textile, paper, leather, metal, ceramic fiber, non-woven adhesive, and foam rubber, latex impregnated products etc.. In addition, with ZnO/MAA, peroxide and high wear furnace HNBR, its comprehensive performance is better than ordinary HNBR.
- Q: How to clean rubber products?
- Rubber molding, after pressing, the elastic body is within the cohesion can not be eliminated, the molding die, often have a very unstable contraction (rubber shrinkage due to rubber vary), required after a period of time, and can be stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, it is necessary to carefully calculate the coordination, if not, it is easy to produce product size instability, resulting in lower quality products.
- Q: Why do rubber products become so long that they seem to melt and become sticky on the surface?
- The main reason for the melting of rubber products is the long usage time or the long time of placing rubber;"Sticky" is because the rubber in the presence of oxygen oxidation reaction, the result is hydroxyl, carboxyl and other polar groups increased. These polar groups are the cause of the sticking of things. In layman's terms, it's equivalent to becoming a self-adhesive.
- Q: What are the causes of chapped rubber products?
- This is the aging phenomenon of rubberAging refers to the polymer materials (including rubber, plastics, fiber and so on) in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors, its performance gradually deteriorated, resulting in the final loss of use value
- Q: How to make rubber products keep brightness for a long time?
- Keep it in the right place: ventilated, dry place, not squeezed
