Q:How to distinguish between rubber and polyvinyl chloride?
Adhesive (Rubber): highly elastic polymeric material with reversible deformation.At room temperature, elastic, in a small rubber under the action of external force can produce greater deformation, remove the external force can restore the original state. Rubber is a completely amorphous polymer, its glass transition temperature is low, the molecular weight is often very large, more than hundreds of thousands.
Q:In addition to the smell of rubber?
Soil recruit: 300 grams of black tea, hot tea, two washbasin water, into the living room, and window ventilation, 48 hours, indoor formaldehyde content will fall by more than 90%, the pungent odor is basically eliminated.
Q:Why is rubber resistant to compression and wear better than metal?
The rubber bushing is made of metal and has a flexible connection. The sheath is made of rubber
Q:There is a crack in rubber products
The additive time temperature and pressure of semi-finished shapes semi-finished semi-finished products placed as far as possible when placed speed gap semi-finished size can be more appropriate to put five percent to ten percent semi finished mixing can put some help curing
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 are the causes of the rubber products breach?
Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.
Q:What is the difference between a thermoforming machine and an injection molding machine in a rubber plant?
A press forming machine is a machine that changes the solid material into a definite shape by pressure. The injection molding machine changes the viscous semi solid to a certain shape by pressure.
Q:What's wrong with rubber whitening?
White: may refer to spray frost (dissolved in more than rubber, drugs in rubber migration to the rubber surface), 1 reasons, excessive drug formulation; 2, sulfur is not complete, the two plus sulfur solution (130 - to 1 hour);It may be a white filler in rubber, so there's no way out. It's only the formula;
Q:Advantages and disadvantages of rubber products
Ding Ji rubber II R(Butyl Rubber) and a small amount of isobutylene isoprene polymerization and, due to steric hindrance of the methyl group than other molecular motion of polymers, so the gas permeability less, resistance to heat, sunlight, ozone, electrical insulation resistance; the polarity of solvent resistance, general use temperature range of -54-110 degrees. Advantages: for most of the general gas with permeability, resistance to sunlight and smell good to be exposed to animal or vegetable oil or chemical gasifiable in. Disadvantages: do not recommend the use of petroleum solvent, rubber, kerosene and aromatic hydrogen, used in automotive tires tube, leather, rubber paper, window frames, rubber, steam hose, heat conveyor belt and so on.
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.
