Q:What is rubber good for making weapons?: Rubber is needed for vehicles, tires, rubber boats, clothing, shoes, medical devices, etc.

Q:What is the pressure on rubber products during vulcanization?: The vulcanization pressure in the process of processing is the pressure on the unit area in the process of vulcanization. In general, in addition to rubberized products, other rubber products are required to exert some pressure during vulcanization. Vulcanization pressure mainly has the following points:1) prevent the bubbles from forming bubbles in the process of vulcanization and improve the compactness of the products.2) the filling flow of the filling material is driven by the power to fill the mold cavity.3) to improve the adhesion between rubber and cord and the bending resistance of products.4) improve the physical and mechanical properties of vulcanized rubber (i.e. products).

Q:The action of various ingredients in rubber formula: Curing system: vulcanizing agent, accelerator, active agent, anti coke agent,

Q:Why should the tire be made of rubber?: Rubber not only has excellent wear resistance, long service life, but also has good elasticity. As a tire, it can absorb a lot of vibration energy, which is conducive to the smooth running of the car. So rubber will be used as a tyre for cars.

Q:What are the causes of fracture in rubber products?: If it is because of aging and fracture, this is a normal phenomenon, is not a problem in the safe use period, there is to pay attention to the storage environment, avoid direct sunlight, the best placed in the shade, not stored in a humid environment.

Q:What are the common rubber products, please tell me: Rubber is a high elastic polymer compound, which has high elasticity that other materials do not have, so it is also called elastomer. Its main feature is the enormous molecular weight

Q:How much is the recipe for Buddha's rubber?: Bo siangong Zhejiang university disciplinary advantage and analysis of detection rely on talent, with a variety of methods of analysis and testing, has accumulated rich experience in chemical products analysis, qualitative analysis and quantitative identification of unknown compounds through professional, reliable, comprehensive separation and detection means for adjusting the formula, in the research and production of new product development, to provide scientific production process improvement on the basis of, can also according to customer needs, provide follow-up technical guidance.

Q:How to make white rubber products do not yellow or delay yellowing time?: 1, raw material itself yellow degeneration, for example, NR aging resistance than SBR and BR difference.2, the matching of accelerant system. The accelerator can use DM and M to achieve yellow change 4, but the whole system needs to be adjusted. The use of anti yellowing enhancers such as two dithiocarbamate on yellow Bianyou benefits, but at the expense of great property and operation. The faster the sulfidation rate, the less the chance of breaking the chain, and the aging degree is restrained. But at the same time sacrificing the comprehensive nature. The cross-linking bonds generated by rapid vulcanization and slow vulcanization are different. For example, tension, tear and so on, are greatly affected. But the elasticity brittleness will increase.

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.

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.
