FAQ
- 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
- Classification of other rubber sheets of wear-resistant rubber plates
- RIT flat wear-resistant plywoodNon slip and relatively ordinary wear, usually used in less tension fabric, nylon belt, roller wrap, or ordinary environment of the drum wrapped plastic processing.RIT type wear resistant rubber plateThe surface of the rubber plate is of a rhombus shape, which has a strong anti slip and abrasion resistance. It is usually used in the fabric belt and middle and high strength steel belt and roller package processing. It is the most frequently used roller wrapped rubber sheet at present. Especially 10mm and 12mm thick rhombus rubber sheet.
- What material is the rubber used in the tires?
- Natural rubber (NR) is a kind of natural polymer with CIS -1, 4- polyisoprene as the main component, the molecular formula is n (C5H8), the composition of 91% ~ 94% is rubber hydrocarbon (CIS -1, 4- polyisoprene), the protein, fatty acid, carbohydrate, ash and other non rubber substances. Natural rubber is the most widely used universal rubber.Polybutadiene rubber is cis polybutadiene rubber -1,4-, its molecular formula is n (C4H6). Polybutadiene rubber is synthetic rubber regular structure formed by the polymerization of butadiene, the CIS content of more than 95%. According to the different catalysts can be divided into nickel, cobalt, titanium and rare earth polybutadiene rubber (nd). Polybutadiene rubber is the second largest after the synthetic rubber sbr. Compared with natural rubber and styrene butadiene rubber, it is especially excellent in cold resistance, wear resistance and elasticity after vulcanization. It has less heat under the dynamic load and has good aging resistance. It is easy to use with natural rubber, chloroprene rubber or nitrile rubber. Polybutadiene rubber is especially suitable for the manufacture of automobile tires and cold products, also can produce cushioning materials and various rubber, adhesive tape, adhesive tape and sponge etc.
- What are the hazards of rubber accelerators?
- Many have carcinogenic substances, long-term contacts are not too good, attention to protection is also necessary.
- What's rubber skin?
- Rubber is divided into natural rubber and synthetic rubber by raw materials. According to the form is divided into block rubber, latex, liquid rubber and rubber powder. Latex as a rubber colloidal water dispersion; liquid rubber as an oligomer of rubber, not before the vulcanization is generally viscous liquid; powder rubber is the latex processing into powder, in order to benefit ingredients and processing. Thermoplastic rubber, developed in 1960s, does not require chemical vulcanization and is shaped by thermoplastic processing. Rubber according to the use of divided into general and special type of two categories.
- How to improve the aging resistance of rubber?
- In the course of oxidation, ozone can produce molecular cracks, but also make the deformed rubber crack in the direction of stress, namely ozone cracking".Heat will increase the temperature, thermal cracking or thermal crosslinking of rubber will accelerate the oxidation rate of the rubber, that is, heat aging.
- How should the rubber products be dirty?
- First coated with vinegar on the top, after dry, and then wipe paper, so clean
- How to improve the mobility of rubber material
- Formulation design should ensure that the rubber has good scorch performance and is favorable for the full flow of the adhesive in use.
