Q:EPDM rubber foam?
Its characteristics: due to the internal foaming material containing a large amount of air or other gas, and should not be in circulation, especially the closed cell foam, with independent foam completely separated, material can obviously slow down on the heat conduction coefficient of heat conduction, very basic, more softness of the material itself, and good elasticity, can be used as the car, insulation materials, household appliances, ship electronic equipment, medical equipment, fitness equipment, such as the ideal air conditioning pipeline...
Q:Process for producing rubber products
Rubber elastic, lack of necessary processing plasticity properties, therefore not easy to process. In order to improve the plasticity, so the rubber mastication, so the mixing of ingredients easily dispersed in rubber, which also helps to improve the permeability of the fabric into rubber and molding in rolling and molding process. The long chain molecular degradation were called plasticity forming process of mastication. Mechanical plastication and mixing two kinds of thermoplastic plastic mixing method of rubber. Mechanical plasticization is the reduction of long chain rubber molecules at shorter temperatures through the mechanical extrusion and friction of the extruder, which changes from a high elastic state to a ductile state. Hot hot mastication is to pass into the rubber in the compressed air in the heat and oxygen under the effect of the degradation of long chain molecules to obtain shorter plasticity.
Q:What is the composition of the vulcanizing agent for silica gel?
Since the invention of vulcanized rubber has so far has been the main sulfur vulcanizing agent of natural rubber and most diene general synthetic rubber, while the emergence of many new curing agent to improve the performance of rubber products from the full use of significant, but the price is generally more expensive, it is still the main sulfur. Metal oxide is a special vulcanizing agent for chloroprene rubber. In addition to selenium and tellurium, other non sulfur compounds are mainly used in saturated rubber and special synthetic rubber, and peroxide is the most important.
Q:The silica gel of the kettle is the white one that is waterproof and leaked out
Natural rubber (NR) is mainly composed of rubber hydrocarbons (polyisoprene), containing a small amount of protein, water, resin acids, sugars and inorganic salts. The utility model has the advantages of large elasticity, high extension strength, high tear resistance and electrical insulation, good abrasion resistance and drought resistance, good processability, easy adhesion to other materials, and superior performance in synthetic rubber in comprehensive performance. The disadvantage is that oxygen and ozone resistance is poor, easy aging, metamorphism, oil and solvent resistance is bad, resistance to acid and base corrosion is low; heat resistance is not high. Temperature range: about 60 DEG C 80. Make tires, rubber shoes, hose, tape, wire and cable insulation and sheath, and other general products. The utility model is especially suitable for making torsional vibration eliminator, engine shock absorber, machine support, rubber metal suspension element, diaphragm and molded 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:Is there any poison in the processing and testing of rubber products? What about the salary?
With some raw materials are generally low in rubber products, such as sulfur, amine antioxidant, lead salt, nickel salt what.In addition, when processing or testing, if there is temperature, pay attention to good protection.As far as salaries are concerned, generally 2k-3k, of course, there is a difference between local manufacturers.
Q:How can rubber products be softened?
Softener generally need to add a certain amount of plasticizer in rubber processing. It is usually of low softness to make the rubber softMolecular substances, they can increase the plasticity of rubber, liquidity, adhesion, in order to facilitate molding and molding and other process operations. It can also help the powder mixture to disperse and reduce the mixing temperature, at the same time, it can reduce the viscous flow temperature and the glass transition temperature of rubber, and improve the low temperature resistance of rubber.
Q:What is the difference between vulcanized rubber and butyl rubber?
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.
Q:How are rubber wires processed?
Extrusion processExtrusion process is through extrusion machine, barrel, cylinder wall and screw member role, so that the plastic to achieve extrusion and preliminary shape purposes, extrusion process, also known as extrusion process.Extrusion process is the main equipment extruder.Extrusion characteristics of several rubber: natural rubber extrusion speed, shrinkage of semi-finished products is small. The body temperature 50-60, head of 70-80 C, 80-90 type C; styrene butadiene rubber extrusion speed, compression deformation, surface roughness, body temperature 50-70, the temperature of 70-80 DEG C, die temperature is 100-105 DEG C; chloroprene rubber extrusion without sufficient thermal refining, body temperature of 50 DEG C, nose, mouth and 70 DEG C; ethylene propylene rubber extrusion speed, small shrinkage, body temperature 60-70, the temperature of 80-130 DEG C, C type 90-140. Acrylonitrile butadiene rubber extrusion performance is poor, extrusion should be fully hot refining. The body temperature is 50-60 degrees, and the nose temperature is 70-80 degrees centigrade.
Q:The difference between plastic rubbers and rubber boots.
Plastic and rubber are high molecular material, mainly composed of two kinds of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, fluorine, silicon, sulfur atoms, its special properties, use is also special. At room temperature, the plastic is not solid, hard, and tensile deformation of rubber hardness is not high., elastic, can be stretched, and stop pulling back to normal. This is due to differences in their molecular structure. Another difference is the plastic can be repeatedly recycled, while the rubber cannot be directly recycled, can only be processed and then reclaimed rubber, plastic and rubber. Available in the form of more than 100 to 200 degrees at 60 to 100 degrees. The morphological similarity does not include plastic rubber
