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:What advantage does ethylene propylene rubber with three yuan compare to two yuan ethylene propylene rubber?
Because the two EPDM molecules containing double bonds, not curing, which limits its application. In the ethylene propylene rubber commodity brand, two yuan ethylene propylene rubber accounts for only about 10% of the total. While the three rubber vulcanization available, which has been widely used, and become the main varieties of ethylene propylene rubber, ethylene propylene rubber in the commodity brands accounted for about 90%. At present, third monomers commonly used in the industrial production of three yuan ethylene propylene diene monomer are ethylene glycol norbornene (ENB), dicyclopentadiene (DCPD) and 1, 4- (HD).
Q:How can I make rubber products brighter?
Special release agent for rubber products, release agent.Mold release agent is an interface coating used on two surfaces that are easy to adhere to each other. It can make the surface of the material easy to break off, smooth and clean. Mold release agent is used in various molding processes, such as glass fiber reinforced plastics, metal die casting, polyurethane foam and elastomer, injection molding thermoplastic, vacuum foaming sheet and extrusion section. In molding, sometimes other plastics, such as plasticizers, leak to the interface, and then a surface remover is needed to remove it.
Q:What solvent is used to clear the melted rubber layer?
Remove the melted rubber layer with chloroform or toluene solvent.Rubber is a latex made from rubber, tree, rubber, and grass. It is made of flexible, insulating, impermeable and air. High elastic polymer compound. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber, tree, rubber, grass and other plants. The synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life.
Q:Does anyone know how to deal with the frosting of rubber and how to prevent it?
The situation of frost spray often occurs in rubber products, except for formulation reasons and weather. From the stage of occurrence, it may happen before sulfuration or after sulfuration.
Q:What's the difference between plastic and rubber?
Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, noise elimination, and excellent performanceAnd rubberRubber (Rubber): highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands. ,Relatively direct, that is, plastic hard, rubber soft (not exactly, there are many exceptions, but most of them are)
Q:What kinds of vulcanized rubber do you have?
According to the appearance of rubber: rubber can be divided into solid rubber (also known as dry rubber), emulsion rubber (referred to as latex), liquid rubber and powder rubber four categories.
Q:What is the pressure on rubber products during vulcanization?
Usually, the selection of curing pressure need to consider several factors, namely rubber formulation, rubber plastic size, forming die structure (filling pressure, injection pressure, injection type), type of curing equipment (flat vulcanizing machine, vulcanizing machine, injection machine, injection of sulfur with sulfide vacuum machine etc.) and product structure features.
Q:Several aspects of rubber aging performance and how to identify them
The chemical activity of ozone and ozone is much higher than that of oxygen, and it is more destructive. It also breaks the molecular chain, but the effect of ozone on rubber varies with the deformation of rubber. As for the deformation of the rubber (mainly unsaturated rubber), and there should be crack force perpendicular to the direction of the so-called "ozone cracking"; effect on the deformation of the rubber, only surface oxide film without cracking.
Q:Can the rubber surface be painted with paint?
Rubber surface painting, rubber will have an impact on the long time will crack!
