Q: Rubber and metal have to be sealed before they are too strong: Different materials and O-ring O-ring compression the change of general material such as NBR, NR, nitrile rubber, natural rubber, chloroprene rubber CR, EPDM three EPDM, HNBR hydrogenated nitrile rubber, silica gel SILICOME SBR Buna, styrene butadiene rubber, SBR, acrylate rubber ACM, compression O-ring or the 20% to calculate. If it is a special material FKM, VITON, PU, FLS silicon fluorine rubber, fluorine rubber, polyurethane, compression of these materials is calculated by 15% o ring.

Q: Why do rubber products Blister?: Foaming reasons of rubber products:1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, the vulcanizing pressure is insufficient, the detained gas and sulfur volatile matter can not be discharged in time.3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the rubber material in the steam, air free precipitation.

Q: How to maintain and store the rubber material?: When storing, matters needing attention are:(1) should be stored in a ventilated, dry environment, the relative humidity of the air is 50% ~ 80%.(2) should be stored in non corrosive media, and away from the heat source, the temperature is about 5 degrees Celsius conditions(3) packing should be kept as far as possible without box stacking

Q: Does anyone know how to deal with the frosting of rubber and how to prevent it?: To reduce blooming, mainly by adjusting the formula to achieve, such as reducing the amount of antioxidant in summer, storage time is short before vulcanization, if you can consider the use of paraffin wax, microcrystalline wax, if sulfur spray frost can consider changing into insoluble sulfur. Because I don't know your recipe, I adjust it according to the actual situation.

Q: How is rubber made? What kind of equipment do you need? How much is it?: The main raw material is rubber, rubber products with various agents, as well as the fiber and metal skeleton material, the basic production process of rubber products including plastication, mixing, calendering, extrusion, molding, curing 6 basic processes.

Q: What is rubber leather?: The general rubber has good comprehensive properties and is widely used. The main contents are as follows: natural rubber. From the latex of the Hevea tree, the basic chemical composition is cis polyisoprene. Good elasticity, high strength and good comprehensive performance. Isoprene rubber. The full name is cis -1, 4- polyisoprene rubber, a high CIS synthetic rubber made from isoprene, because of its structure and properties similar to natural rubber, it is also called synthetic natural rubber. Styrene butadiene rubber. Referred to as SBR, made by copolymerization of butadiene and styrene. According to the production method, emulsion polymerization, styrene butadiene rubber and solution polymerized styrene butadiene rubber are divided into emulsion polymerization. Its comprehensive properties and chemical stability are good. The br. The full name is cis -1, 4- polybutadiene rubber, referred to as BR, made from butadiene polymerization. And the other than universal rubber, vulcanized butadiene rubber cold resistance, abrasion resistance and excellent elasticity, dynamic load, less heat, good aging resistance, easy and natural rubber, chloroprene rubber, nitrile rubber and etc..

Q: Rubber products are not allowed to touch oil products, but why can rubber gloves be contacted daily? What's the point?: Most rubber materials are not resistant to oil, some rubber materials are resistant to oil, such as nitrile rubber, etc., the family commonly used detergent on rubber gloves did not affect.

Q: Why do rubber products become so long that they seem to melt and become sticky on the surface?: The main reason for the melting of rubber products is the long usage time or the long time of placing rubber;"Sticky" is because the rubber in the presence of oxygen oxidation reaction, the result is hydroxyl, carboxyl and other polar groups increased. These polar groups are the cause of the sticking of things. In layman's terms, it's equivalent to becoming a self-adhesive.

Q: What's the difference between a rubber track and a plastic runway? Or is it just a thing, really answer?: Basically, it's the same thing. It is made of waste rubber or plastic granules wrapped with polyurethane resin and pigments and laid on the floor.

Q: How can rubber products be softened?: Softener generally need to add a certain amount of plasticizer in rubber processing. It is usually of low softness to make the rubber softMolecular substances, they can increase the plasticity of rubber, liquidity, adhesion, in order to facilitate molding and molding and other process operations. It can also help the powder mixture to disperse and reduce the mixing temperature, at the same time, it can reduce the viscous flow temperature and the glass transition temperature of rubber, and improve the low temperature resistance of rubber.
