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:How to improve the hardness of rubber?
1. selection of high Mooney rubber (high molecular weight);2., increase the dosage of reinforcing agent, or choose the reinforcing agent with high structure and large specific surface area;3. reduce the amount of plasticizer, softener, or use viscosity high plasticizer;4. proper increase of gum content;5., improve the degree of cross-linking (increase the amount of vulcanizing agent, appropriately prolong the curing time, etc.);6., use stiffening resin, high styrene and other hardening agent;7. rubber and plastic combination;8. reduce plasticizing and prevent over refining;
Q:Bought a mouse pad, a little rubber, how to remove?
The best way is to put the balcony outside, let it go to taste naturally, generally a few days can be, do not expose to the sun, we are all solved like this.The mouse pad more or less have to taste, taste the most common cloth pad, because the part is in addition to cloth rubber, relatively the rubber is not very high, even as the high-end gaming mouse pad will have a pungent taste, which is unable to avoid, but really I don't smell in use also, not in the mood to smell, unless you put the nose close to become obvious.It is best not to wash casually or rub some potions, this will only backfire, and occasionally wash the mouse pad, you can, because the wash will be more degumming.
Q:What is the role of softening plasticizers in rubber? How are they classified?
Rubber plasticizer refers to add certain substances in rubber, can make the force rubber molecules is reduced, thereby reducing the glass transition temperature of the rubber, the rubber plasticity and fluidity, easy calendering and extrusion molding operation, but also can improve the mechanical properties of the vulcanizate of some physical machines, such as the decrease of hardness and elastic constant tensile stress, with high and low heat, improve the cold tolerance.
Q:Is rubber flame retardant?
Mainly to see the use of related products, for example, the glass door rubber strip is flame retardant, and the vehicle's internal and external tires are not flame retardant.
Q:What are the common rubber products, please tell me
Rubber products mainly include tires, sidewall, rubber strips and inner tubes, as well as parts of automobiles. They are made of wires, cables, wrapping and high voltage and extra high voltage insulating materials. They can also make rubber shoes and guardOther light colored products, such as raw materials, and other general industrial rubber products, cushioning materials, conveyor belts and belts, oil resistant hoses, gaskets, and chemical resistanceCorrosion equipment lining.
Q:How to distinguish between rubber and polyvinyl chloride?
1) preparation: vinyl chloride monomer (vinyl, chloride, monomer, referred to as VCM) in peroxide, azo compounds and other initiators; or under the action of light and heat, polymerization by the principle of free radical polymerization of polymers. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins.2) properties: white powder, amorphous structure, degree of branching is small, the relative density of about 1.4, the glass transition temperature of 77~90 DEG, 170 DEG C to decompose, the stability of heat and light, at 100 DEG C or after long time exposure to sunlight, will decompose and produce hydrogen chloride, and further automatic catalytic decomposition that change, the physical and mechanical properties also decreased rapidly, in the practical application must be added in order to improve the stability of heat and light stabilizer of the.
Q:UV glue can glue rubber products?
If you want to completely recover, do not see the crack, in addition to professional factories, individuals can not reach this technology for the time being
Q:What is the tensile strength of silicone rubber?
The main characteristics of silicone rubber:High and low temperature performance, the range is -100-300 degrees centigrade.Ozone aging, heat resistance, oxygen aging and weather aging are good.The electric insulation performance is good, can do high-grade insulation products.It has excellent biomedical properties, non-toxic and tasteless.Good sealing performance.
Q:Rubber products are not allowed to touch oil products, but why can rubber gloves be contacted daily? What's the point?
Contact every day is not every day inside the bubble, the contact time is short, the impact on rubber is very small.Raw rubber rubber products are: natural rubber, isoprene rubber, nitrile rubber, EPDM rubber, polybutadiene rubber, styrene butadiene rubber, polyurethane rubber, chloroprene rubber, silica gel etc.
