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.

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.
• Normal requirement of flange surface finishing which contact with gasket.

Q:What is the relationship between synthetic rubber and crude oil?
Synthetic rubber is a kind of polymer material made of petroleum and natural gas as raw material and polymerized with diene and olefin as monomers.The main purpose of the industrial synthesis of rubber material is cost saving, improving the properties of rubber products, because the natural rubber products price is more expensive, in order to reduce the cost of enterprises have invested a lot of synthetic rubber materials with low cost.
Q:How does rubber mobile phone cover change yellow?
Rubber aging process often accompanied by some significant phenomena, such as the appearance of natural rubber can be found in long-term storage of soft, sticky, spots; rubber deformation, brittle, hard, cracking, mildew, loss of light and color change.
Q:What is the cause of the bursting of rubber products and how should they be improved?
There are five reasons for the bursting of rubber products: 1. forming temperature is too high, or the temperature of the upper and lower template is inconsistent. 2. the exhaust line is too open or exhaust time is too late. 3., the material quickly cooked. 4., the mold structure is irrational, there is no running trough. 5., down weight, overweight.
Q:What are the common rubber products, please tell me
Generally in one hundred thousand, and even reach about million, followed by rubber is the size of the molecular weight varies. Latex extracted from rubber trees, rubber, grass, etc.
Q:Excuse me, what is in the rubber rubber, glue them, what is the difference?
The toughness greatly improved than rubber glue. If the car tire is cooked. Generally the same thickness, soft as glue.
Q:Is there any poison in the processing and testing of rubber products? What about the salary?
There will be some flavor at the time of processing, as well as some fillers, oil will be a little toxic, and some crosslinking agents may be toxic. But now the mixer extruder is mostly closed, so it is common to pay attention to respiratory protection.A mechanical test is usually less toxic, and a glove is enough.If you do thermal testing, such as TGA, DMA, DSC and so on, it will degrade and release small molecules, especially if the aromatic oil is filled, be sure to pay attention to.
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 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:What are the application fields of waste tire rubber powder?
Waste tire rubber powder from 900 to 1200 waste tire as the main raw material, the production method of low temperature refrigeration by air turbine (0.425mm) 40 mesh to 200 mesh (0.0750mm) crumb rubber with high fineness, tensile strength, the proportion of small, good liquidity.
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.
