Q: What solvent is used to clear the melted rubber layer?
Natural rubber is made from latex, and a portion of the non - rubber contained in the latex is left in the solid rubber. In general natural rubber contains rubber hydrocarbon 92%-95%, but not rubber hydrocarbon accounts for 5%-8%. Because of the different processing methods, different habitats and even different seasons, the proportion of these ingredients may vary, but basically within the scope.Proteins can promote the vulcanization of rubber and retard aging. On the other hand, the protein has strong water absorption, can cause rubber moisture absorption, mildew, insulation degradation, protein and increase heat generation shortcomings.
Q: What kinds of rubber are edible grade safety rubber?
1, natural rubber: often used in the manufacture of condoms, pressure cooker sealing ring and so on;2 butyl rubber: as a result of good sealing performance, often used as infusion bottles and oral liquid bottle rubber stopper;3. Food grade silica gel: high pressure cooker with long life cycle.
Q: What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?
The Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM) are approximately:Rubber elastic modulus 0.0078GPa, Poisson's ratio 0.47.
Q: What advantage does ethylene propylene rubber with three yuan compare to two yuan ethylene propylene rubber?
In recent years, the third monomer and new technology development, foreign developed 1 7- octadienoic, 6, 5, two 10- methyl -1, 9- eleven, 7- two three ene 3, methyl -1, 6- octadienoic, 5 7-, two methyl -1, 6- octadienoic, 7- methyl -1, 6- octadiene as the three EPDM third monomer, the performance of three Yuan rubber has been enhanced. The monomer and content of third monomer in three yuan ethylene propylene rubber have direct influence on vulcanization rate and vulcanizate property. Among them, dicyclopentadiene (DCPD) as the third monomer, although the price is low, but the three Yuan rubber vulcanization speed is slow, difficult and high degree of unsaturation diene rubber and use; to ethyiidenenorbomene (ENB), 6 10-, two methyl -1, 5, third monomer three Yuan rubber vulcanization speed 9- eleven three ene as fast, the former has become the main varieties of three yuan of ethylene propylene rubber. The third monomer content in iodine said three EPDM iodine value is generally 6-30, mostly around 15. The iodine value is 6-10, curing speed is slow, difficult and high unsaturated rubber; iodine value is 25-30, for ultra high speed curing type, available in any proportion and high unsaturated diene rubber and use. Therefore, three yuan ethylene propylene rubber and other rubber in use, should pay attention to choose the appropriate three yuan ethylene propylene rubber varieties.
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: How can I make rubber products brighter?
Consider cleaning with an alkaline solution. Regular soap is fine.If you did not meet the requirements, can go to the market to buy some special cleaning agent.
Q: Excuse me, what is in the rubber rubber, glue them, what is the difference?
The toughness greatly improved than rubber glue. If the car tire is cooked. Generally the same thickness, soft as glue.
Q: Why does rubber stink?
Because of the original gum problem, such as PU or polyurethane will have a foul smell.Highly elastic polymer material with reversible deformation of rubber. 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: What kind of material does the shockproof rubber cushion usually choose? What's the hardness?
Recommend the use of EPDM, its good elasticity, although lower than natural rubber, isoprene rubber and butadiene rubber but its resistance to aging, corrosion resistance, chemical resistance, resistance to high pressure steam performance advantage, so compared to choose EPDM.Shock absorbing rubber used to be the only adhesive for NR in the past. In recent years, in order to meet the requirements of increasing heat resistance and oil resistance of automobiles, IIR, EPDM, NBR and CR have also begun to be used, and even microcellular PU elastomers and TPE thermoplastic elastomers have appeared. In addition, according to automotive requirements, in order to achieve lightweight targets, plastics have begun to replace metal, so-called rubber and plastic shock absorption rubber products.
Q: What are the bridge rubber air bags used for?
After the concrete is poured, the vibrating bar is vibrated simultaneously from both sides, so as to prevent the core mold from moving to the left and the right. And the vibration bar segment head can not touch the core mold, so as not to wear and tear gas leakage.
