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.

- Q: What's the difference between plastic and rubber?
- Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, noise elimination, and excellent performanceAnd rubberRubber (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. ,Relatively direct, that is, plastic hard, rubber soft (not exactly, there are many exceptions, but most of them are)
- Q: What is the specific gravity of natural rubber?
- Natural rubber is elastic high polymer compound natural rubber tree cultivation, by cutting off the latex prepared by the steps of dilution, filtration, condensation, rolling and drying, commonly known as raw rubber or rubber. According to different preparation methods, there are wrinkle sheet gum, tobacco sheet glue and so on.
- Q: Is silicone good or rubber good?
- We can see from their properties, silicone rubber has the superiority of the ordinary rubber silicone rubber prices There is nothing comparable to this, more expensive, which is better, we should look at our purpose, if ordinary rubber products can meet our needs, it is not necessary to overkill, with better performance, higher prices of the silica gel.
- Q: Several aspects of rubber aging performance and how to identify them
- The chemical activity of ozone and ozone is much higher than that of oxygen, and it is more destructive. It also breaks the molecular chain, but the effect of ozone on rubber varies with the deformation of rubber. As for the deformation of the rubber (mainly unsaturated rubber), and there should be crack force perpendicular to the direction of the so-called "ozone cracking"; effect on the deformation of the rubber, only surface oxide film without cracking.
- Q: What is rubber material?
- The molecular chain of rubber can be crosslinked, and the crosslinked rubber can recover quickly when it is deformed by external force, and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of rubber industry. It is widely used in making tyres, rubber hoses, tapes, cables and other kinds of rubber products.
- Q: Half finished rubber film surface white is going on
- 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: How can rubber products prevent fading?
- That is to add UV absorbers, white, then add more titanium dioxide, there is no good way, as well as your choice of pigment, as far as possible difficult to fade, such as inorganic pigments.
- Q: What is a rubber accelerator? What role?
- Usage: This product is a kind of accelerator for chloroprene rubber, chlorinated polyvinyl chloride rubber, epichlorohydrin rubber and polyacrylate rubber. The utility model is suitable for metal oxide as a vulcanizing agent, especially when Magnesium Oxide and Zinc Oxide are used as vulcanizing agents. Safe operation, not easy to burn. This product is especially suitable for 54-1 (W) and general GN chloroprene rubber. It is easy to disperse, no pollution and no discoloration in the rubber. In the general product, the dosage is 0.25-1.5, in the 54-1 (W) chloroprene waterproof product, the dosage is 0.2-0.5 parts, and should be accompanied by 10-20 parts of lead oxide.Packaging and storage of 25Kg plastic paper composite bag, kraft paper bag or plastic container. Store in a cool, dry and airy place. Avoid the sun.
- Q: Is polyurethane and polyurethane rubber one thing?
- Polyurethane is a very special polymer, it is composed of hard and soft segments, the hard part of Tg is very low, with plastic characteristics, soft section of Tg is higher than room temperature, a lot of rubber characteristics. In the process of synthesis of polyurethane, by controlling polymerization, the proportion of hard segment and soft segment of polymer can be adjusted, so that polyurethane can be expressed as plastic or rubber.Rubber shoes, excluding plastic shoes, should not be included in general sense. Common sense says in rubber overshoes, it is the waterproof shoe that rains commonly, army shoe, plastic shoe has slipper commonly.
- Q: How to improve the aging resistance of rubber?
- In the course of oxidation, ozone can produce molecular cracks, but also make the deformed rubber crack in the direction of stress, namely ozone cracking".Heat will increase the temperature, thermal cracking or thermal crosslinking of rubber will accelerate the oxidation rate of the rubber, that is, heat aging.
