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.

2.Features of Gasket :
• Perfect sealing performance.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.
• Heat treatment industry for furnace parts, fans, tube hangers, and baskets and trays to hold small parts.
• Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide.
•  Food processing industry.
• Hot acetic and citric etc.

Q:The silica gel of the kettle is the white one that is waterproof and leaked out
Butadiene styrene rubber (SBR) copolymer of butadiene and styrene. Performance is close to natural rubber, is the largest yield of general-purpose synthetic rubber, characterized by wear resistance, aging resistance and heat resistance, more than natural rubber, texture is more natural rubber uniform. Disadvantages are: low elasticity, anti bending, anti tear performance is poor; the processing performance is poor, especially the poor, low strength self adhesive rubber. Temperature range: about 50 DEG C + 100. Mainly used instead of natural rubber to make tires, rubber sheets, hose, rubber shoes and other general products.
Q:Process for producing rubber products
In the production process of rubber products, the process of making various shapes and sizes is made by using a calender or an extruder, which is called forming. Forming methods are1. rolling formingThe utility model is suitable for making simple sheet and plate shaped articles. It is a method of pressing compound rubber into a certain shape and a certain size of film by calender. It is called calendering forming. Some rubber products, such as tires, adhesive tape, hose and other textile fiber materials, must be coated with a thin layer of glue on the fiber, also known as glue or glue, the process of gluing is generally completed on the calender. Fiber material needs drying and dipping drying before calendering. The purpose is to reduce moisture content of fiber material, avoid evaporation and foaming, and increase the temperature of fiber material, so as to ensure the quality of calendering process. Dipping is a necessary process before cementing. The purpose is to improve the bonding property of fiber and rubber.2. extrusion moldingFor more complex rubber products, such as tyres, tread, hose, and wire surface coating, shall be made by extrusion molding. It is a method of continuous molding with a certain plastic compound into the extruder's hopper, the extrusion of the screw under the internal screw, and through a variety of dies, also known as the templates. Before extrusion, the material must be preheated to make the material soft and easy to extrude so as to obtain a smooth and accurate rubber product.3. moldingIt can also be used to make some rubber products with complex shapes, such as leather bowl and sealing ring. The rubber material is placed in the mold and shaped by heating.
Q:What is the role of softening plasticizers in rubber? How are they classified?
The plasticizer used in the production process should meet the following conditions: good plasticizing effect, low dosage, quick absorption, good compatibility with rubber, low volatility, no migration, cold resistance, water resistance, oil and solvent resistance, heat resistance, light resistance, good insulation, good flame resistance resistant bacteria, colorless, non-toxic, cheap and so on.But in fact, it is impossible to fully satisfy the above-mentioned conditions of plasticizers. Therefore, in actual use, more than two or more kinds of plasticizers mixed use, in order to make up for each other, where the amount of commonly known as the main plasticizer, and the other called auxiliary plasticizer.
Q:Is it necessary to use rubber products for steel structure buildings?
There must be a rubber cushion for the gear of the crane beam, and there is also a rubber cushion between the crane track and the crane beam. Of course, not all deformation joints are rubber, depending on how to choose the design node.
Q:How can rubber products prevent fading?
Light and white rubber products are prone to yellowing in the course of use and storage, thus affecting appearance and quality, resulting in various economic disputes and irreversible losses.
Q:Rubber Mooney value is what meaning, what is the role of
Mooney viscosity (Mooney viscosity) also called rotation (Mooney) is determined by numerical viscosity, Mooney viscometer, synthetic rubber can basically reflect the degree of polymerization and molecular weight. The rotor is a standard Mooney viscometer, at a constant speed (2 RPM), rotating in a closed chamber in the sample the viscosity change of shear resistance. The size of the sample and the rotation of the rotor during the curing process, through the force measuring device is displayed on the dial to Mooney units, at the same time interval can be read Mooney, vulcanization curve, door number rose after the first drop, 5 unit increase in the time from the lowest point called the Mooney scorch time, the Mooney scorch and then increased to 30 units and the time that scorch time.
Q:The action of various ingredients in rubber formula
Curing system: vulcanizing agent, accelerator, active agent, anti coke agent,
Q:What is a rubber accelerator? What role?
Thiofide ETU (Na-22), Thiofide DETU, Thiofide ZDC (EZ), Thiofide ZDMC (PZ) Thiofide ZDBC (BZ), Thiofide ZMBT (MZ), Thiofide TMTM, Thiofide MBT (M), Thiofide MBTS (DM)
Q:Half finished rubber film surface white is going on
Because inside the rubber compounding agent reachsupersaturation, rubber compounding agent near surface precipitates first, then from the inner to the surface migration of precipitation when complexing agent in the rubber to reduce its saturated state, precipitation process ended. Causes the complexing agent to achieve the supersaturation state, causes the rubber spraying frost the main reason to have: the rubber formula design is improper, the craft operation is not proper, the raw material quality fluctuates, the storage condition is poor, the product owes sulfur, the product aging and so on.
Q:What are the causes of fracture in rubber products?
If there is a fracture after production, it is necessary to consider whether or not the method of forming plastic material is unreasonable and where there is no improvement. Finally, it is reasonable to observe whether the structure of the grinding tools is reasonable.
