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.

Q:What is the tensile strength of silicone rubber?
The tensile strength range of silicone rubber is 3.4-14.7Mpa, depending on the formula!
Q:How much is the recipe for Buddha's rubber?
Rubber products were analyzed by infrared spectroscopy (FTIR), nuclear magnetic resonance (1H, NMR), mass spectrometry (MS), X diffraction analysis (XRD), ICP-MS, X fluorescence spectrometry, ion chromatography analysis, and other means. Through these testing methods can be a good solution for rubber products formulations, rubber products in the role of a detailed understanding of the more convenient for each enterprise research and development, grasp the market dynamics.
Q:Why do rubber products Blister?
Foaming reasons of rubber products:1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, the vulcanizing pressure is insufficient, the detained gas and sulfur volatile matter can not be discharged in time.3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the rubber material in the steam, air free precipitation.
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:What problems need to pay attention to when inflating the pipe?
Rubber pipeline plugging bag should keep the inner pressure of the gasbag is uniform when inflated, inflated slowly rising inflation, observe the pressure gauge without change, such as pressure gauge shows rapid rise in inflation is too fast, the inflation rate should slow down, stop valve will tighten slightly, reduce the inlet velocity, or the speed is too fast, faster than pressure is likely to break into the rubber balloon. - Zhang
Q:What are the hazards of waste rubber and how can they be used for regeneration?
In addition to piling up waste rubber products as fuel burning, scientists have been studying more effective waste rubber regeneration technology since 1910. Reclaimed rubber refers to the physical and chemical processes such as comminution, heating and mechanical treatment of waste vulcanized rubber, which can change from elastic state to vulcanized rubber with plasticity and viscosity. The essence of the regeneration process is the comprehensive effect in heat, oxygen, mechanical function and recycling agent of chemical and physical functions, make the network vulcanizate degradation, the fracture position of both crosslinks, also have large molecular cross-linking bond between. Rubber regeneration methods can be broadly divided into two categories: physical regeneration and chemical regeneration.
Q:Advantages and disadvantages of rubber products
Ding Ji rubber II R(Butyl Rubber) and a small amount of isobutylene isoprene polymerization and, due to steric hindrance of the methyl group than other molecular motion of polymers, so the gas permeability less, resistance to heat, sunlight, ozone, electrical insulation resistance; the polarity of solvent resistance, general use temperature range of -54-110 degrees. Advantages: for most of the general gas with permeability, resistance to sunlight and smell good to be exposed to animal or vegetable oil or chemical gasifiable in. Disadvantages: do not recommend the use of petroleum solvent, rubber, kerosene and aromatic hydrogen, used in automotive tires tube, leather, rubber paper, window frames, rubber, steam hose, heat conveyor belt and so on.
Q:What is the size of the scorch time of the rubber?
Rubber scorch characteristics usually use 120 degrees Mooney scorch time Ts said, also available vulcameter determining curing curve on the T10 or TA1, TA2 said, the scorch time and process, the rubber accelerator process conditions, the hardness of the rubber material and rubber material return use and other factors. Generally soft rubber is 10-20min; most of the stock (excluding high filling hard or high temperature 35-80min) is 20-35min; the high filling hard material is.
Q:What's the difference between silicone rubber and 703.704 glue?
704, temperature range of -50-250, better temperature effect, mainly used for sealing electric heating devices; electric plug sealing; instrument, instrument bonding and sealing.
Q:What is rubber leather?
Special rubber refers to rubber with some special properties. The main contents are as follows: chloroprene rubber. CR, prepared by polymerization of chloroprene. With good overall performance, oil resistance, combustion resistance, oxidation resistance and ozone resistance. But its density is larger, it is easy to crystallize at room temperature, hard to store, cold resistance is poor. Nitrile rubber. Referred to as NBR, made by copolymerization of butadiene and acrylonitrile. Good oil resistance and aging resistance. It can be used in the air of 120 degrees Celsius or in the oil at 150 degrees centigrade for a long time. In addition, it also has water resistance, air tightness and excellent adhesive properties. Silicone rubber. The backbone consists of alternating atoms of silicon and oxygen, with organic groups on silicon atoms. High and low temperature, ozone resistance, good electrical insulation. Fluorine rubber. A synthetic rubber containing fluorine atoms in the molecular structure. Usually, the number of fluorine atoms in the fluorine containing unit in the copolymer is expressed as fluorine rubber 23, and the copolymer is two vinylidene fluoride and three fluorine vinyl chloride. Fluorine rubber, high temperature, oil resistance, chemical resistance. Polysulfide rubber. Condensation of two halides with sulfides of alkali or alkaline earth metals. Has excellent oil resistance and solvent resistance, but the strength is not high, aging resistance, poor processability, odor, and more with nbr. In addition, there are polyurethane rubber, epichlorohydrin rubber, acrylic rubber and so on.
