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. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support. These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.
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.
• Perfect sealing performance.
• Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide.
•  Food processing industry.

Q:What solvent is used to clear the melted rubber layer?
The acetone extractives are some fatty acids and steroids, some natural antioxidants and accelerators, and can help with the powdery agent in the process of mixing and dispersion of rubber softening effect.Ash containing mainly magnesium phosphate and calcium phosphate salts, copper, manganese, iron and other metal compounds is very small, because these valence metal ion can promote the aging of rubber, so their content should be controlled.
Q:What are the causes of fracture in rubber products?
Rubber products appear broken phenomenon, mainly for the following reasons:1, rubber products for a long time led to the phenomenon of fracture;2, too tired lead to rubber products broken;3, long-term exposure to ultraviolet light will cause rubber products broken;4, in the production of the use of chemical additives and materials conflict, resulting in incompatible and broken;5, the production process, the release of time is not appropriate, resulting in fracture (such as scratches);6, abrasive structure is irrational, lead to fracture;7, the use of materials is irrational, leading to fracture is also common;8, materials placed too long, in use, resulting in broken products, resulting in waste.
Q:What is the composition of the vulcanizing agent for silica gel?
Vulcanizing agent is organic peroxide, or bridging agent, used for curing silicone rubber (Xi Likang), EVA and curing of unsaturated polyester.
Q:How is rubber made? What kind of equipment do you need? How much is it?
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.
Q:What plastic rubber will not be subjected to oil (such as transformer oil) by quality (e.g., aging, dissolution)?
Plastic and rubber are high molecular material, mainly composed of two kinds of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, fluorine, silicon, sulfur atoms, its special properties, use is also special. At room temperature, the plastic is not solid, hard, and tensile deformation of rubber hardness is not high., elastic, can be stretched, and stop pulling back to normal. This is due to differences in their molecular structure. Another difference is the plastic can be repeatedly recycled, while the rubber cannot be directly recycled, can only be processed and then reclaimed rubber, plastic and rubber. Available in the form of more than 100 to 200 degrees at 60 to 100 degrees. The morphological similarity does not include plastic rubber.
Q:Rubber products labeled Huai gum can improve wear?
In accordance with the requirements of the inquiry, the tire carbon black is a special production, usually oil to produce, mainly in the heavy oil products, coal, coal tar and other raw materials as a result of incomplete combustion
Q:Why should the tire be made of rubber?
Early rubber was made from latex of rubber trees, rubber grass and other materials made of flexible, insulating, impermeable and air. Rubber is a high elasticity of high polymer compounds, divided into two kinds of 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 is the role of softening plasticizers in rubber? How are they classified?
The plasticizer used in the production process should meet the following conditions: good plasticizing effect, low dosage, quick absorption, good compatibility with rubber, low volatility, no migration, cold resistance, water resistance, oil and solvent resistance, heat resistance, light resistance, good insulation, good flame resistance resistant bacteria, colorless, non-toxic, cheap and so on.But in fact, it is impossible to fully satisfy the above-mentioned conditions of plasticizers. Therefore, in actual use, more than two or more kinds of plasticizers mixed use, in order to make up for each other, where the amount of commonly known as the main plasticizer, and the other called auxiliary plasticizer.
Q:Comparison of physical properties of HNBR rubber material with other rubber materials
Hydrogenated nitrile rubber (HNBR) is a highly saturated elastomer obtained by the special hydrogenation of nitrile butadiene rubber. Hydrogenated nitrile rubber has good oil resistance (of fuel oil, lubricating oil, aromatic solvent resistance and good); and due to their high saturation, which has good heat resistance, excellent chemical resistance (of freon, acid and alkali resistance is good, excellent) ozone resistance, high anti compression permanent deformation performance; at the same time the hydrogenated nitrile rubber also has high strength, high tear resistance, excellent wear resistance and other characteristics, is one of the most outstanding performance of the rubber.
Q:Rubber Mooney value is what meaning, what is the role of
In accordance with the provisions of the standard GB 1232 (Mooney viscosity), rotation expressed by the symbol Z100 C 1+4. Where Z rotational viscosity; 1, preheating time is 1min; 4 - rotation time is 4min; 100 C - test temperature of 100 degrees.In our country, usually with ML100 or MS100 1+4 to 1+4 DEG C said. M said L Mooney, represented by the greater trochanter, S said with a small rotor.1 preheat for 1 minutes, 4 said that the test for 4 minutes. The larger the value of Mooney viscosity, said, the plastic is widely used as a low. Index control process performance of rubber.
