Product Description:

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. It could be standard style,it just formed stainless steel and graphite or non asbestos etc.
It could be add inner ring or outter ring.The material ring  could be carbon steel or stainless steel.

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.

Q:How to improve the hardness of rubber?
1. selection of high Mooney rubber (high molecular weight);2., increase the dosage of reinforcing agent, or choose the reinforcing agent with high structure and large specific surface area;3. reduce the amount of plasticizer, softener, or use viscosity high plasticizer;4. proper increase of gum content;5., improve the degree of cross-linking (increase the amount of vulcanizing agent, appropriately prolong the curing time, etc.);6., use stiffening resin, high styrene and other hardening agent;7. rubber and plastic combination;8. reduce plasticizing and prevent over refining;
Q:What solvent is used to clear the melted rubber layer?
Remove the melted rubber layer with chloroform or toluene solvent.Rubber is a latex made from rubber, tree, rubber, and grass. It is made of flexible, insulating, impermeable and air. High elastic polymer compound. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber, tree, rubber, grass and other plants. The synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life.
Q:What material is the rubber used in the tires?
The tyre is known, usually made of rubber materials, a solid tire and pneumatic tire parts, pneumatic tyre and tubeless tire composed by.
Q:NR natural rubber manufacturers, who knows Guangdong here, there are manufacturers, a few hair connection is OK
Butadiene styrene rubber (SBR) copolymer of butadiene and styrene. Performance is close to natural rubber, is the largest yield of general-purpose synthetic rubber, characterized by wear resistance, aging resistance and heat resistance, more than natural rubber, texture is more natural rubber uniform. Disadvantages are: low elasticity, anti bending, anti tear performance is poor; the processing performance is poor, especially the poor, low strength self adhesive rubber. Temperature range: about 50 DEG C ~100. Mainly used instead of natural rubber to make tires, rubber sheets, hose, rubber shoes and other general products.
Q:How do soft silicone rubber print?
Silicone ink, printed with silk screen just fineSoft silica gel, also called soft conductive silica gel, is a kind of heat transfer interface material. It is a sheet material. It can be cut arbitrarily according to the size and shape of the heating power. It has good thermal conductivity and insulation characteristics
Q:What are the uses of rubber oil?
The so-called "rubber oil" is only a generic term, in different places of use, there are different titles. In synthetic rubber plants, in order to improve some properties of rubber, it is necessary to charge mineral oil to synthetic rubber, which is called rubber filling oil. For rubber products factory, downstream enterprises produce all kinds of rubber products, they tend to be rubber oil called rubber processing oil, rubber processing oil, rubber softener and so on. Whatever we call them, we can call them rubber oil, or rubber oil.
Q:What kind of material does the shockproof rubber cushion usually choose, What's the hardness?
The air tightness of butyl rubber is the best of all the rubber, is its biggest advantage, it is mainly used for tyres, although there are shock absorbing function, but dynamic flex is not ideal.
Q:Rubber and metal have to be sealed before they are too strong
Different materials and O-ring O-ring compression the change of general material such as NBR, NR, nitrile rubber, natural rubber, chloroprene rubber CR, EPDM three EPDM, HNBR hydrogenated nitrile rubber, silica gel SILICOME SBR Buna, styrene butadiene rubber, SBR, acrylate rubber ACM, compression O-ring or the 20% to calculate. If it is a special material FKM, VITON, PU, FLS silicon fluorine rubber, fluorine rubber, polyurethane, compression of these materials is calculated by 15% o ring.
Q:What about rubber molding, foaming and layering?
2. rubber or mold contaminated by grease or other impurities and layered in contaminated areas3. release agent too much spray, so that part of the invasion of rubber, resulting in delamination, cracking4. mixing uneven or spray cream5. plastic material is too bad
Q:What are the causes of the rubber products breach?
Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.
