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.

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.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.

Q:Why is rubber forest a green desert?
Rubber is a plant in tropical rain forests, but not native to tropical rainforests in Xishuangbanna. Before the world know it, the growth of rubber trees in South America's Amazon jungle, as long as cut open a gap, there will be a sap from the trunk stream, in the Indian language it is called the "cry of the tree".
Q:What are the application fields of waste tire rubber powder?
Waste tire rubber powder modified asphalt for highway, waterproofing materials, modified concrete, modified coating, railway sleepers, rubber brick, machine pad, cushion, cushion and other types of subgrade gasket and fenders, sound-absorbing materials, road sealant, shoes, carpet padding, tire pad, car body, bottom sealing rings miscellaneous pieces of rubber, etc..
Q:Several aspects of rubber aging performance and how to identify them
Rubber and rubber products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the physical and chemical properties and mechanical properties of rubber gradually deteriorated, and finally lose value, this kind of change is called aging of rubber
Q:What are the hazards of rubber accelerators?
I have been engaged in the rubber industry for many years. I personally think that the accelerator has no harm to people. Wearing gloves, masks and protective measures during operation will not be harmful.
Q:What is the difference between a thermoforming machine and an injection molding machine in a rubber plant?
A press forming machine is a machine that changes the solid material into a definite shape by pressure. The injection molding machine changes the viscous semi solid to a certain shape by pressure.
Q:Is rubber flame retardant?
Rubber itself is flammable, in the production process can be filled with some flame retardant material, it can reduce its flammability, but at the same time reduce its inherent good performance, such as abrasion resistance, elasticity, etc..
Q:How can I get rid of the rubber?
One way is to use rubber deodorant is a kind of used to remove or reduce the acid degradation, all kinds of rubber produced in the processing or in the process of the use of alkoxy compounds, aldehydes, vinyl compounds, ammonia, CO2 plastic smell of chemical additives, the smell if inhaled for a long time will stimulate the senses give a person, discomfort or even harmful to the body, have two times of pollution to the environment, the chemical composition of different varieties of rubber and odor molecules are different, and in the actual development of Chinese ocean chemistry and etc. Ma'anshan Keli chemical is used in chemical chelation is also used, is the other mechanism, in addition to taste rubber both the rubber agent itself, also want to consider a variety of additives such as odor curing agents released, in addition to the use of rubber ingredients to improve rubber products and improve the level of environmental protection, rubber The production environment is of great help to the comprehensive utilization of regenerated rubber resources. A form of powder or liquid used in rubber, usually based on odor and odor characteristics
Q:Rubber soaked with hot water will not come out harmful substances?
There are many kinds of rubber. Some kinds of hot water will not soak out harmful substances, such as neoprene, used to make gaskets
Q:What are the forming methods of rubber products?
In rubber products, the main molding technologies are molding, forming, transfer, forming, wrapping, molding and injection molding.
Q:What do you pay attention to when using rubber?
The greater the polarity of the rubber, the better the bonding effect. Among them, nitrile butadiene chloroprene rubber is of great polarity and strong adhesive strength. Natural rubber, silicone rubber and isobutyl rubber have less polarity and weak cohesive force. In addition, the rubber surface often has the release agent or other free out auxiliaries, hinders the adhesive effect.Adhesive is used to connect rubber, and the concrete methods are divided into hot sticking method and cold sticking method.Hot sticking method is realized by adhesive plastication of unvulcanized rubber and glued rubber together after curing, the method is complicated, need to heating and pressurizing equipment, inconvenient to use.Cold adhesive method is to apply the adhesive to the surface of the glued product. After airing, fold it and solidify it at room temperature. Of course, proper heating can shorten the curing time and increase the bonding strength. Cold sticking method is simple and energy saving. It is a good method to be popularized.
