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 :
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:Process for producing rubber products
There are many kinds of rubber products, but the production process is basically the same. The basic process of rubber products in general solid rubber - rubber as raw materials including: plastication, mixing, calendering, extrusion, molding, curing 6 basic processes. Of course, raw materials preparation, finishing, inspection, packaging and other basic processes are indispensable. The processing of rubber mainly deals with the contradictory process of plasticity and elasticity. Through a variety of techniques, the elastic rubber plastic rubber has become the addition of various additives made of semi-finished products, and then through the vulcanization has semi-finished plastic and rubber products into high elasticity and good mechanical performance.
Q:Properties and specific uses of various rubbers
1, natural rubber: mainly used for tires, hoses, tape and other rubber products.2, synthetic rubber: divided into general and special synthetic rubber, synthetic rubber, synthetic rubber such as polybutadiene rubber, styrene butadiene rubber mainly used in the production of tires, rubber shoes, rubber products.
Q:What kind of product is suitable for rubber trimmer? Where's the rubber trimmer?
Trimming machines are mainly used in wood chamfering, metal trimming, strip grinding and other motor type movable trimming equipment. Chamfering machine.Stationary trimmerGenerally used for metal strip trimming, that is, after the strip of metal strips with a fixed tool to remove burr or chamfer on both sides of the required radian,Scope of application: used in tableware, stationery, hardware, sheet metal and other special equipment industry.
Q:What advantage does ethylene propylene rubber with three yuan compare to two yuan ethylene propylene rubber?
In recent years, the third monomer and new technology development, foreign developed 1 7- octadienoic, 6, 5, two 10- methyl -1, 9- eleven, 7- two three ene 3, methyl -1, 6- octadienoic, 5 7-, two methyl -1, 6- octadienoic, 7- methyl -1, 6- octadiene as the three EPDM third monomer, the performance of three Yuan rubber has been enhanced. The monomer and content of third monomer in three yuan ethylene propylene rubber have direct influence on vulcanization rate and vulcanizate property. Among them, dicyclopentadiene (DCPD) as the third monomer, although the price is low, but the three Yuan rubber vulcanization speed is slow, difficult and high degree of unsaturation diene rubber and use; to ethyiidenenorbomene (ENB), 6 10-, two methyl -1, 5, third monomer three Yuan rubber vulcanization speed 9- eleven three ene as fast, the former has become the main varieties of three yuan of ethylene propylene rubber. The third monomer content in iodine said three EPDM iodine value is generally 6-30, mostly around 15. The iodine value is 6-10, curing speed is slow, difficult and high unsaturated rubber; iodine value is 25-30, for ultra high speed curing type, available in any proportion and high unsaturated diene rubber and use. Therefore, three yuan ethylene propylene rubber and other rubber in use, should pay attention to choose the appropriate three yuan ethylene propylene rubber varieties.
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:Rubber rolling process for making rubber products
Rubber mastication is force, heat, oxygen or adding some chemical agents and other methods should be made by mechanical, rubber transition from elastic state for strengthening soft, easy processing of plastic process.Rubber mastication is designed to reduce its elasticity, increase the plasticity, and obtain adequate liquidity, mixing, rolling, extrusion, molding, curing and glue manufacturing, sponge and other manufacturing process to meet the requirements of.Mastering proper plasticity of plastic is essential to the processing of rubber products and the quality of finished products. The plastic degree should be reduced as much as possible in order to meet the requirements of processing technology. With the appearance of constant viscosity rubber and low viscosity rubber, some rubber is no longer need to be refined and mixed directly.
Q:What is the size of the scorch time of the rubber?
Rubber is a mixture of organic and inorganic compounds. The main component is organic matter, and the scorch time can reflect the weather resistance and fire resistance of the product.
Q:What is the difference between silicone rubber and silicone rubber?
Silica gel is also called "silicon rubber" because of different fields so organic silica gel has become an indispensable tools in our lives, but also more than a silica silica aggregate, silica gel in the molding of silicone products manufacturers is a popular said polysiloxane silicone rubber is only a kind of synthetic rubber is a kind of non-toxic solid silicone silicone rubber. Because no accurate statement so that both of them are called organic silica gel, silica gel is a kind of solid crystal, by molding to produce silicone products applied to various places with liquid silicone are two production methods, such as "silicone" after the encounter them divided into organic and inorganic silica gel, silica or must be clear is polysiloxane synthetic silicon rubber, can also be understood as the silicon rubber is silicon A synthetic silicone rubber.
Q:What is the temperature of ordinary silicone rubber resistant to low temperature?
Because the molecular structure of silicone rubber is amorphous, the temperature has little influence on its properties, and it has good cold resistance. The brittleness temperature of the general organic rubber is from -20 DEG C to -30 DEG C, while the brittleness temperature of the general silicone rubber is between -60 and -70 degrees centigrade. When the rubber is introduced in 7.5 (mol)% phenyl, brittle temperature of silicone rubber can be reduced to -115 DEG C, remain elastic at -90 DEG C and can use.
Q:What about rubber molding, foaming and layering?
Return the glue (the rubber has not been used up after heat treatmentThe glue and the new rubber are mixed together to heat up, and the remaining glue is called a return glue. When the mixture is mixed with the new rubber, the mixture is uneven and the degree of vulcanization is not uniform, resulting in delamination
