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 :
1.A.Wound style gasket consists of four type:basic type,with inner ring,with outer ring,and with inner and outer rings. B.Heat exchanger wound style gasket:basic type and with inner and outer rings.
2. Normally matrial used:
A.Steel tape:08F,0Cr18Ni9(304),0Cr18Ni9Ti,1Cr18Ni9Ti(321),0Cr17Ni12,M02(316),00Cr17Ni14M02(316L).
B.(Cold roll)steel plate for inner and outer ring:Outer ring:mild steel,0Cr13 and 0Cr18Ni9

Q:Why is rubber forest a green desert?
Long ago, the people have the knowledge of the use of wild rubber. Before Columbo came to the new world, no one outside the Americas knew that there was a species called rubber, and never thought that there would be a magical liquid out of the tree trunk that could change the progress of human civilization one day.
Q:What kinds of vulcanized rubber do you have?
According to the sources and methods of raw materials: rubber can be divided into two categories: natural rubber and synthetic rubber. Among them, the consumption of natural rubber accounted for 1/3, and the consumption of synthetic rubber accounted for 2/3.
Q:What are the causes of cracks in vulcanized rubber products?
Vulcanized rubber refers to vulcanized rubber, has the characteristics of constant viscosity, not easy to break, and rubber products are mostly made of this kind of rubber. Also known as "mature rubber", commonly known as rubber or rubber. Vulcanized rubber is a polymer compound, its monomers are CIS poly butadiene monomer -CH2-CH=CH=CH2- 1, 3- in the double bonds were open to the -S-S- curing agent, will connect the linear structure of polybutadiene rubber mesh structure.
Q:Are there formaldehyde in rubber products, too?
Yes, because formaldehyde is a very good organic solvent, so the general rubber varieties contain formaldehyde.
Q:What kind of materials should be used for rubber products to keep the brightness of the mirror for a long time?
It is important to use recycled material as a high light material. If the selected material is not available, then it is not effective. It must be pure, only ABS.PMMA, or PC/ABS. There is material, it is best not to contain white material, mottled with a little transparent, is the best.
Q:Excuse me, is PU one kind of silicone? Or what is the connection between the two?
Silica gel (Silica gel; Silica) alias: silicone rubber is a highly active adsorption material, belongs to amorphous material, its chemical formula is mSiO2. NH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemical stability, in addition to strong alkali and hydrofluoric acid, do not react with any substance. Different types of silica gel have different microporous structures because of their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics which are difficult to be replaced by other similar materials: high adsorption properties, good thermal stability, stable chemical properties, high mechanical strength, etc.. According to the size of the pore size, silica gel is divided into large pore silica gel, coarse pore silica gel, B type silica gel and pore silica gel.
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:How do ordinary NBR and EPDM materials differ?
Nitrile rubber (NBR) is composed of butadiene and acrylonitrile was prepared by emulsion polymerization, nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are low temperature resistance, poor ozone resistance, poor insulation properties, and slightly lower elasticity. Nitrile rubber is mainly used in the manufacture of oil resistant rubber products.
Q:Explain why butyl rubber is more resistant to oxidation and aging than other elastomers, such as natural rubber
The macromolecular structure unit of natural rubber is isoprene, and the macromolecular chain is mainly composed of CIS -1, 4 polyisoprene. NR is the mechanical and processability comprehensive properties of all rubbers
Q:Why does rubber burn black smoke?
Rubber is filled with black carbon, which is used to dye, but to increase hardness, burning black smoke.
