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.
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.

- Q: Are there formaldehyde in rubber products, too?
- 1, stimulation: mainly affect performance of formaldehyde for the stimulation of the skin and mucous membrane, formaldehyde is a protoplasmic poison, can bind with protein, when high concentrations of inhaled respiratory severe irritation and edema, eye irritation, headache.2, sensitization: skin direct contact with formaldehyde can cause allergic dermatitis, pigmentation and necrosis, inhalation of high concentrations of formaldehyde can cause bronchial asthma.3. Mutagenicity: high concentration formaldehyde is a genotoxic substance. Laboratory animals can cause nasopharyngeal tumors at high concentrations in the laboratory.
- Q: Rubber soaked with hot water will not come out harmful substances?
- There are many kinds of rubber. Some kinds of hot water will not soak out harmful substances, such as neoprene, used to make gaskets
- Q: What is the pressure on rubber products during vulcanization?
- It can be seen that the vulcanization time can be shortened by increasing the sulfuration temperature. The process of high temperature vulcanization is injection vulcanization and electric heating flat vulcanization. Both of them can be cured at 160 DEG C or even higher. In recent years, the industry has also adopted the trend of high temperature vulcanization. In addition, the continuous vulcanization process using eutectic liquid as heating medium has also begun to use high temperature vulcanization. In the rubber injection molding process, because the rubber material has passed the preheating and plasticizing of the screw, higher vulcanization temperature (such as 175~183 DEG C) can be adopted, but the reversion or sulfuration of rubber is less affected. For example, for three yuan ethylene propylene rubber, when set 160 degrees for molding, the positive curing time is 60min, if it is changed to 200 degrees noteThe time of vulcanization is only 4min. With the use of general-purpose rubber to make small products, the vulcanization time can be l-2mm.
- Q: How can the frictional properties of rubber improve?
- Because of its high elasticity and low modulus, the friction and wear properties of rubber are greatly affected by their physical and mechanical properties. The hardness of rubber is smaller, contacting with a rigid object, the real contact area is large, and the real size of the contact area is an important factor, so the friction rubber hardness, have more effect on the friction performance.
- Q: Is polyurethane and polyurethane rubber one thing?
- Polyurethane, plastics and rubber are made of polyurethane resin polymer composite material, the specific material and production process is different, resulting in polyurethane polymer chain molecular weight and performance of different.Polyurethane can also be used in coatings, adhesives and other fields, the use is very extensive.
- Q: How do you remove the black dirt on the rubber?
- Apply toothpaste to the stain and brush it again and again as clean as newWith Senna water and kerosene on rubber and iron grinding interpolation results are goodThe black dirt on the rubber can also be removed by diluting it with alcohol
- Q: What do you pay attention to when using rubber?
- The greater the polarity of the rubber, the better the bonding effect. Among them, nitrile butadiene chloroprene rubber is of great polarity and strong adhesive strength. Natural rubber, silicone rubber and isobutyl rubber have less polarity and weak cohesive force. In addition, the rubber surface often has the release agent or other free out auxiliaries, hinders the adhesive effect.Adhesive is used to connect rubber, and the concrete methods are divided into hot sticking method and cold sticking method.Hot sticking method is realized by adhesive plastication of unvulcanized rubber and glued rubber together after curing, the method is complicated, need to heating and pressurizing equipment, inconvenient to use.Cold adhesive method is to apply the adhesive to the surface of the glued product. After airing, fold it and solidify it at room temperature. Of course, proper heating can shorten the curing time and increase the bonding strength. Cold sticking method is simple and energy saving. It is a good method to be popularized.
- Q: What are the causes of the rubber products breach?
- First: the use of rubber joints in the process of linking the length is not enough to force beyond the length of the link, the expansion of the scope of contraction may also splitSecond: rubber joints, the strength of the link is relatively low, then if the adhesive method is not accurate, the strength of the joint will be lower, there may be crackingThird: rubber joints after installation, in other places free here beyond the extension range of pipe strap, there may be cracking.Fourth: rubber joints in the outdoor adverse weather, explosion, sun, etc., lower than the use of temperature may also crack.Fifth: in the process of production of vulcanized rubber joint used in rubber function is not good or has been since sulfur failure, excessive grinding, wire rope and other parts of the rust, the joint strength will be greatly reduced, when in use, will likely easily disconnect joint phenomenon
- Q: What is the harm of rubber to the human body?
- In use, some contact with the human body rubber requirements are very high, from the choice of gum species (usually silicone rubber and PU), to the use of mixing agents, have strict requirements.
- Q: What are the disadvantages of a rubber roof?
- Housing rubber roof area must be greater than the housing area, mainly for water and rubber, heat up, cold weather.
