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 gasket is formed with stainless steel 304/316 and graphite,non asbestos,ptfe or other seal material. 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.
• 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.

Q:How much is the recipe for Buddha's rubber?
The structure of natural rubber is a polymer of isoprene, and later appeared in many new varieties of synthetic rubber, mainly such as polybutadiene rubber, chloroprene rubber, styrene butadiene rubber and so on. The yield of synthetic rubber has greatly exceeded that of natural rubber, of which the largest yield is styrene butadiene rubber.
Q:What kind of rubber does TPE belong to?
Thermoplastic elastomer TPE (Thermoplastic, Elastomer) is a kind of material with high elasticity, high strength, high resilience, and has the characteristics of injection molding. Nontoxic security, wide range of hardness, with excellent color, soft touch, weather resistance, fatigue resistance and temperature resistance, excellent processing performance, without curing, can reduce the cost of recycling, can be two times of injection molding, and PP, PE, PC, PS, ABS and other base materials the adhesive, can also be a separate molding.
Q:Is work in rubber products harmful to health?
In the manufacture of rubber products, the rubber itself is not toxic, but some agents are toxic, so most of the factories are now using intelligent small drug batching system, to avoid direct contact with the human body. In use, some contact with the human body rubber requirements are very high, from the choice of gum species (usually silicone rubber and PU), to the use of mixing agents, have strict requirements. If the general use, such as tires, seals and so on, and the body does not matter much.
Q:What are the forming methods of rubber products?
Calendering is the process in which material is subjected to elongation. The main equipment for rolling forming is three roller or four roller calender. The three roller calender is achieved by rotating the pressure of the two roller. When the rubber material passes through the roller gap, the rubber strip is expanded into a certain sectional shape under the action of pressure, or the process of gluing is realized on the fabric. It is used for sizing, pressing, spinning, gluing and gluing of textile and steel cord, as well as the laminating of film and film, film and adhesive fabric.The basic procedure of calendering process includes: mixing and preheating glue; fabric guiding and drying (and sometimes dipping); rubber sheeting in four roll and three roll calender on or in textile and rubberized calendering semi-finished products cooling, crimping, cutting and placing etc..In rolling before the need to preprocess the rubber and textile, rubber calender before entering, to turn it in the hot refining mill, this process is called thermal refining or preheating, the purpose is to improve the mixing uniformity of refined rubber material, further increase the plasticity, increasing the temperature increase high plasticity. In order to improve the bonding performance of rubber and textile, ensure the rolling quality, need drying of the textile fabric, moisture content control in 1% ~ 2%, the moisture content is too low, the textile hardens, easily damaged during the calendering, high water content, poor adhesion.
Q:Properties and specific uses of various rubbers
1, natural rubber: mainly used for tires, hoses, tape and other rubber products.2, synthetic rubber: divided into general and special synthetic rubber, synthetic rubber, synthetic rubber such as polybutadiene rubber, styrene butadiene rubber mainly used in the production of tires, rubber shoes, rubber products.
Q:How can the rubber shoes be dyed?
And rubber bottom shoes because of its high temperature resistance, low temperature resistance, ductility, have more wear-resistant, so by the majority of sports enthusiasts welcome. Rubber soled shoes when cleaning and maintenance of the need to pay attention to the following: any rubber outsole, high flexibility, abrasion resistance, anti slip and other characteristics, but in the smooth floor (such as marble floor tiles, etc.) with water, will lose the slip function, so please be careful in the consumer when.
Q:What are the ingredients in the tires?
Tires include rubber, polymers, sulfur, carbon black, and other chemicals. Each tire contains more than 150 components, so in the tire production process, from raw material processing to the tire baking to the end, the process is complicated and long.
Q:UV glue can glue rubber products?
If you want to completely recover, do not see the crack, in addition to professional factories, individuals can not reach this technology for the time being
Q:What's rubber skin?
The general rubber has good comprehensive properties and is widely used. The main contents are as follows: natural rubber. From the latex of the Hevea tree, the basic chemical composition is cis polyisoprene. Good elasticity, high strength and good comprehensive performance. Isoprene rubber. The full name is cis -1, 4- polyisoprene rubber, a high CIS synthetic rubber made from isoprene, because of its structure and properties similar to natural rubber, it is also called synthetic natural rubber. Styrene butadiene rubber. Referred to as SBR, made by copolymerization of butadiene and styrene. According to the production method, emulsion polymerization, styrene butadiene rubber and solution polymerized styrene butadiene rubber are divided into emulsion polymerization. Its comprehensive properties and chemical stability are good. The br. The full name is cis -1, 4- polybutadiene rubber, referred to as BR, made from butadiene polymerization. And the other than universal rubber, vulcanized butadiene rubber cold resistance, abrasion resistance and excellent elasticity, dynamic load, less heat, good aging resistance, easy and natural rubber, chloroprene rubber, nitrile rubber and etc..
Q:The difference between plastic rubbers and rubber boots.
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
