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:For the application of common synthetic rubber, not too long or too difficult, want to do
Polybutadiene rubber (BR) is formed by polymerization of butadiene rubber CIS structure. The advantages are: flexibility and excellent abrasion resistance, good aging resistance, low temperature resistance is excellent in heat under dynamic load is small, easy to metal bonding. The disadvantage is low strength, tear resistance, processability and self-adhesive poor. Using temperature range: - 60 DEG C ~ + 100 DEG C. The general and natural rubber or butadiene rubber and tire tread, main production and transportation with cold and special products.
Q:Doors and windows shock absorber seals, rubber blocks, rubber products, do not know where to buy, where suppliers?
The product has good elasticity and anti compression deformation, and has excellent aging resistance. It adopts the microwave vulcanization process to form at one time. The surface is smooth and beautiful, without any trace.
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:Is work in rubber products harmful to health?
The raw material of rubber products is rubber compound, and the rubber compound has five components:Main rubber. Rubber main glue is not toxic.Reinforcing agent. Most of the reinforcing agents are not toxic.Softener. Is the most emollient mineral oils, high temperature volatile hazardous substances.Antioxidant. Some poisonous.Vulcanizing agent. The vulcanizing agent is generally sulfur, sulfur will release a high temperature sulfur dioxide, sulfur dioxide, sulfur dioxide, hydrogen sulfide gas three.
Q:How can rubber products prevent fading?
Light and white rubber products are prone to yellowing in the course of use and storage, thus affecting appearance and quality, resulting in various economic disputes and irreversible losses.
Q:The action of various ingredients in rubber formula
The main raw rubber: decide the use performance, process performance and product cost, service life.The operating system: plasticizer, softener, peptizer, solubilizer, homogenizing agent, dispersing agent, thickening agent, lubricant
Q:What is the definition of mixed rubber?
Chemical property:Synthetic rubber is composed of different monomers under the action of the initiator, the polymerization of polymers of variety, monomer, styrene, butadiene acrylonitrile, isobutylene, chloroprene etc.. There are four kinds of polymerization process: emulsion polymerization, solution polymerization, suspension polymerization and bulk polymerization.
Q:What plastic rubber will not be subjected to oil (such as transformer oil) by quality (e.g., aging, dissolution)?
The most essential difference between plastics and rubber is plastic deformation when plastic deformation occurs, while rubber is an elastic deformation. In other words, it's not easy to restore the original state after plastic deformation, and rubber is relatively easy. Plastic elasticity is very small, usually less than 100, while rubber can reach 1000 or more. Most of the molding process of plastics is finished
Q:What do you pay attention to when using rubber?
The greater the polarity of the rubber, the better the bonding effect. Among them, nitrile butadiene chloroprene rubber is of great polarity and strong adhesive strength. Natural rubber, silicone rubber and isobutyl rubber have less polarity and weak cohesive force. In addition, the rubber surface often has the release agent or other free out auxiliaries, hinders the adhesive effect.Adhesive is used to connect rubber, and the concrete methods are divided into hot sticking method and cold sticking method.Hot sticking method is realized by adhesive plastication of unvulcanized rubber and glued rubber together after curing, the method is complicated, need to heating and pressurizing equipment, inconvenient to use.Cold adhesive method is to apply the adhesive to the surface of the glued product. After airing, fold it and solidify it at room temperature. Of course, proper heating can shorten the curing time and increase the bonding strength. Cold sticking method is simple and energy saving. It is a good method to be popularized.
