Q:How to remove the peculiar smell of rubber products?
The general method is to add some flavor spices used to degrade or reduce all kinds of rubber produced in the processing or use process in acids, alkoxy compound such as smell, method is effective, but not fundamentally solve the problem.
Q:Why do rubber products Blister?
A lot of reasons, but the main factors are: 1) there are 2 water) mixed rubber Mooney viscosity high fluidity of the compound 3) poor curing pressure lowFrom what you say without adding mold agent foaming phenomenon is more obvious in terms of liquidity, the reason may not glue a problem.
Q:What are the uses of ethylene propylene rubber?
Because of the high strength, good flexibility, high gloss and easy recycling of thermoplastic three yuan EPDM rubber, EPDM/PP has been used as the main material in automobile bumpers and automobile dashboard production both at home and abroad. It is estimated that only two items of bumper and dashboard will be used in 2010, and the annual domestic consumption of EPDM/PP can reach 45 thousand tons. The main processes adopted for the recycling of these products are: first remove the coating of the product surface - grinding - Cleaning - re granulation - adding new materials to produce new products. Thus, a large amount of raw material can be saved and better economic benefits can be obtained in the production of the bumper and the dashboard. The ethylene propylene rubber used in the automotive industry accounts for 42%-44% of the total ethylene propylene rubber in China, excluding the ethylene propylene rubber used by ships, trains and container seals. Because the bonding properties of EPDM rubber is not good, in the tire industry in a large number of materials of tire body and the tread part to promote the use of ethylene propylene rubber, only in the inner tube, white wall, tire strip and other parts of the use of a small amount of ethylene propylene rubber.
Q:Rubber products labeled Huai gum can improve wear?
In accordance with the requirements of the inquiry, the tire carbon black is a special production, usually oil to produce, mainly in the heavy oil products, coal, coal tar and other raw materials as a result of incomplete combustion
Q:Properties and specific uses of various rubbers
Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried.
Q:Rubber rolling process for making rubber products
Rubber mastication is force, heat, oxygen or adding some chemical agents and other methods should be made by mechanical, rubber transition from elastic state for strengthening soft, easy processing of plastic process.Rubber mastication is designed to reduce its elasticity, increase the plasticity, and obtain adequate liquidity, mixing, rolling, extrusion, molding, curing and glue manufacturing, sponge and other manufacturing process to meet the requirements of.Mastering proper plasticity of plastic is essential to the processing of rubber products and the quality of finished products. The plastic degree should be reduced as much as possible in order to meet the requirements of processing technology. With the appearance of constant viscosity rubber and low viscosity rubber, some rubber is no longer need to be refined and mixed directly.
Q:Comparison of physical properties of HNBR rubber material with other rubber materials
HNBR has a high temperature resistance of 130~180 degrees, cold resistance of -55 ~ -38 degrees, and good mechanical properties, compared with other polymers, can meet the requirements of the automotive industry. HNBR with ZnO/ methacrylate (MAA) can be used to make V-belt, triangular V-belt, multi base rubber, vibration isolator and so on. It can also prepare sealing ring, sealing element, heat resisting tube and so on. In oil drilling, rubber products are required to withstand high temperature, high pressure, acid, amines, H2S, CO2, CH4 and other tests of steam. The products prepared by HNBR can be acid resistant, oil resistant and solvent resistant. With the ZnO/MAA HNBR reinforcement can be used for the production of drilling mud pump piston and protection box. In addition, the beating method HNBR can be used as a sealing washer washer made of paper oil industry and automobile industry. HNBR heat and radiation resistance properties than silicon rubber, fluorine rubber, poly four vinyl chloride is better, suitable for all kinds of rubber seals for power station, is also used as a hydraulic pipe, hydraulic seals, power station for cable sheath, can also be used for printing and fabric roller, weapons components and aerospace seals, cover, fuel capsule; HNBR latex can be used as a surface coating (painting), textile, paper, leather, metal, ceramic fiber, non-woven adhesive, and foam rubber, latex impregnated products etc.. In addition, with ZnO/MAA, peroxide and high wear furnace HNBR, its comprehensive performance is better than ordinary HNBR.
Q:How to remove the rubber front?
At present, there are two kinds of machine trimming on the market: roller grinding and cold trimming at normal temperature. If the product added value is not high, not strong to Feng processing precision, recommended by the economic roller milling Xiu Feng, this is the products into the drum, small friction rub off Feng ball and rely on some products produced by each other. The advantage of this approach is that it is relatively economical.
Q:What is rubber material?
Rubber (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.
Q:How do you remove the rubber on your new slippers?
Bamboo charcoal (carbon fired bamboo) can purify the air and remove odors. I think the rubber should also be effective for slippers!
