Q:How to solve the exhaust problem in rubber vulcanization process
Rubber vulcanization process is a process of high temperature, temperature control, temperature will have material evaporation, products not dense gap, excess glue extrusion emissions, sulfide gas release of many factors such as rubber vulcanization requirements must exhaust can produce qualified products.
Q:What is the difference between PVC rubber and ordinary rubber?
PVC is polyvinyl chloride (with "green" sound) vinyl, English PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in peroxide, such as azo compound initiator; or in light, under the action of heat polymerization by free radical reaction mechanism of polymerization of polymers.
Q:What is the relationship between synthetic rubber and crude oil?
Synthetic rubber material also has excellent heat resistance, cold resistance, corrosion resistance, and little affected by environmental factors, synthetic rubber materials and suitable for 60 to 250 degrees below zero normal use.
Q:Can the rubber surface be painted with paint?
The surface of the rubber is sprayed with paint, and it wants to be covered with black paint, but I don't know the effect of paint on rubber for a long time. Rubber is mixed rubber or rubber paint is used!
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:Which kind of rubber has the best wear resistance?
Ding Qing rubber (nitrile, butadiene, rubber)It's also called NBR.Butadiene and acrylonitrile are obtained by emulsion polymerization. NBR is mainly produced by low temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesive force. Its disadvantages are poor resistance to low temperature, poor ozone resistance, poor electrical properties, and slightly lower elasticity.
Q:Is sandal rubber bottom good or polyurethane good?
Rubber material itself poor ventilation, long wearing easily lead to beriberi. And summer rains, if the rain does not drain, will add story.
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.
Q:What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?
Three yuan ethylene propylene is ethylene, propylene and non conjugated diene three copolymer. Diene has a special structure, only one of the two keys to copolymerization, unsaturated double bond, mainly as the chain. Another unsaturated polymer will not become the main chain and will only become side chains. The main polymer chain of three yuan ethylene propylene is completely saturated. This property allows three yuan ethylene propylene to resist heat, light, oxygen, especially ozone. Three yuan propylene is essentially non-polar, resistant to polar solutions and chemicals, low water absorption, and good insulation properties.
Q:What is the size of the scorch time of the rubber?
Rubber scorch characteristics usually use 120 degrees Mooney scorch time Ts said, also available vulcameter determining curing curve on the T10 or TA1, TA2 said, the scorch time and process, the rubber accelerator process conditions, the hardness of the rubber material and rubber material return use and other factors. Generally soft rubber is 10-20min; most of the stock (excluding high filling hard or high temperature 35-80min) is 20-35min; the high filling hard material is.
