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.
2.Features of Gasket :
• Wide range of applicable working condition,high temperature and high pressure resistance,applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium,through change of composition of gasket.
• Strong stress compensation,stable and reliable sealing performance even under frequent pressure fluctuation condition.
• Normal requirement of flange surface finishing which contact with gasket.

- 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: What advantage does ethylene propylene rubber with three yuan compare to two yuan ethylene propylene rubber?
- Because the two EPDM molecules containing double bonds, not curing, which limits its application. In the ethylene propylene rubber commodity brand, two yuan ethylene propylene rubber accounts for only about 10% of the total. While the three rubber vulcanization available, which has been widely used, and become the main varieties of ethylene propylene rubber, ethylene propylene rubber in the commodity brands accounted for about 90%. At present, third monomers commonly used in the industrial production of three yuan ethylene propylene diene monomer are ethylene glycol norbornene (ENB), dicyclopentadiene (DCPD) and 1, 4- (HD).
- Q: What is the definition of mixed rubber?
- Synthetic rubber also has disadvantages, the drawing effect of main disadvantage lies in its relatively poor, tearing strength and mechanical properties are relatively poor, but because of synthetic rubber materials than natural rubber has the advantages of low cost, but also a lot of Companies in the production of low-end products preferred.
- Q: Are natural latex rubber products?
- In the fresh latex without any substance, the rubber hydrocarbon accounts for only 20%-40% of the total amount, and the remainder is a small amount of non rubber components and water.
- Q: What is rubber material?
- Rubber (Rubber): highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands.
- Q: What's rubber skin?
- Rubber (Rubber): highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands.
- Q: How is rubber made? What kind of equipment do you need? How much is it?
- Machining process:This process involves basic processes such as plasticization, mixing, calendering or extrusion, forming and vulcanizing. Each process has different requirements for the product and cooperates with a number of auxiliary operations. In order to make all the necessary coordination agent in rubber, rubber Plasticating must first go through improving the plastic; then by mixing carbon black and all kinds of rubber and rubber additives are evenly mixed into rubber; rubber shaped blank after extruding; and then the textile materials and rolled hanging glue or glue (or metal material) together formed into semi-finished products; finally after vulcanization will have final semi-finished products made of high elastic plastic. The products with higher precision requirements, such as oil seals, O rings and seals, also need trimming and deburring, and manual trimming, mechanical trimming and cold trimming can be used.
- Q: Comparison of physical properties of HNBR rubber material with other rubber materials
- Hydrogenated nitrile rubber, referred to as "HNBR" or "H-NBR". It is a new variety of nitrile rubber (NBR).
- Q: For the application of common synthetic rubber, not too long or too difficult, want to do
- Polybutadiene rubber (BR) is formed by polymerization of butadiene rubber CIS structure. The advantages are: flexibility and excellent abrasion resistance, good aging resistance, low temperature resistance is excellent in heat under dynamic load is small, easy to metal bonding. The disadvantage is low strength, tear resistance, processability and self-adhesive poor. Using temperature range: - 60 DEG C ~ + 100 DEG C. The general and natural rubber or butadiene rubber and tire tread, main production and transportation with cold and special products.
- Q: Rubber products are not allowed to touch oil products, but why can rubber gloves be contacted daily? What's the point?
- Contact every day is not every day inside the bubble, the contact time is short, the impact on rubber is very small.Raw rubber rubber products are: natural rubber, isoprene rubber, nitrile rubber, EPDM rubber, polybutadiene rubber, styrene butadiene rubber, polyurethane rubber, chloroprene rubber, silica gel etc.
