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.These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.
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:
(Cold roll)steel plate for inner and outer ring:Outer ring:mild steel,0Cr13 and 0Cr18Ni9
Inner ring:same as steel t

Q:What's wrong with rubber whitening?
Rubber whitening (spray cream) the main reason for analysis, rubber spray cream, including rubber surface spray and surface spray cream. Spray (Bloom) is a phenomenon in which liquid or solid agents migrate from rubber to rubber surfaces [1]. It can be seen that the inner compound of rubber will precipitate and form a spray. There are three kinds of forms of rubber spray. Powder spraying, wax injection, injection (also known as exudation).1. powder is a curing agent, accelerator, activator, antioxidant and filler powder with precipitation agent on the rubber surface, and form a layer of powder.2. spray wax is paraffin wax, ceresin wax precipitation etc. on the rubber surface, forming a layer of wax.3. fuel injection is softening agent, tackifier, lubricants, plasticizers and other additives in liquid precipitation of the rubber surface, and form a layer of oil.In practice, frost forms on rubber surfaces sometimes appear in one form, sometimes in two or three forms.
Q:Why do rubber products become so long that they seem to melt and become sticky on the surface?
Rubber is a word now often refers to natural rubber, it can be said that not all products are easy to sticky rubber. Natural rubber tends to stick because it contains many carbon carbon double bonds and is prone to oxidation.
Q:What adhesive does rubber and wood have better glue?
Glue is the intermediate between two kinds of materials. It is a kind of fine chemical, which is mainly made of sticky material, physical form, hardening method and classified material. There is a common instant glue (502 common ethyl cyanoacrylate adhesive is a powerful instant), epoxy resin adhesive, anaerobic glue, UV glue (UV curing), hot melt adhesive, pressure-sensitive adhesive, latex etc..
Q:Is vulcanized sole good or rubber sole is good?
Vulcanized soles are vulcanized rubber, after vulcanization, this step of rubber products are not easy to aging, cracking, good elasticity, heat resistance, and now the rubber products are basically this kind of rubber, also known as mature rubber, collectively referred to as rubber or rubber
Q:Rubber Mooney value is what meaning, what is the role of
In accordance with the provisions of the standard GB 1232 (Mooney viscosity), rotation expressed by the symbol Z100 C 1+4. Where Z rotational viscosity; 1, preheating time is 1min; 4 - rotation time is 4min; 100 C - test temperature of 100 degrees.In our country, usually with ML100 or MS100 1+4 to 1+4 DEG C said. M said L Mooney, represented by the greater trochanter, S said with a small rotor.1 preheat for 1 minutes, 4 said that the test for 4 minutes. The larger the value of Mooney viscosity, said, the plastic is widely used as a low. Index control process performance of rubber.
Q:What are the common rubber products, please tell me
Rubber is a high elastic polymer compound, which has high elasticity that other materials do not have, so it is also called elastomer. Its main feature is the enormous molecular weight
Q:Rubber and metal have to be sealed before they are too strong
The percentage difference between the first compression compression = original section diameter minus the trench size divided by the original O ring diameter O-ring compression is mainly depends on the material hardness and O-ring, O-ring if the hardness is 70 degrees, then the O-ring compression is equal to 20%. Of course, the lower the hardness of the O-ring, O-ring compression is greater, mainly used for low pressure places. Then the O-ring hardness increases the amount of compression of the O-ring is smaller, mainly used for high pressure, pressure resistance, resistance of small environment. And so on, the amount of compression can be any hardness O-ring you need.
Q:What is a rubber accelerator? What role?
The accelerator for natural and synthetic gums has a broad range of vulcanization, which can be used alone or in combination with two dithiocarbamate, glucosinolates, guanidine, and other basic promoters. Mainly used in the manufacture of tires, adhesive tape, rubber shoes and other industrial rubber products.
Q:Will rubber products fade?
Rubber products will fade, is a rubber aging process, mainly due to external factors, temperature changes, the use of time, light, chemicals, external force and so on.
Q:What is food grade natural rubber?
Is mainly made of natural rubber, made of natural rubber products, through the relevant national food contact using rubber testing standards, to reach the food grade.
