What are the hazards of waste rubber and how can they be used for regeneration?
- In addition to piling up waste rubber products as fuel burning, scientists have been studying more effective waste rubber regeneration technology since 1910. Reclaimed rubber refers to the physical and chemical processes such as comminution, heating and mechanical treatment of waste vulcanized rubber, which can change from elastic state to vulcanized rubber with plasticity and viscosity. The essence of the regeneration process is the comprehensive effect in heat, oxygen, mechanical function and recycling agent of chemical and physical functions, make the network vulcanizate degradation, the fracture position of both crosslinks, also have large molecular cross-linking bond between. Rubber regeneration methods can be broadly divided into two categories: physical regeneration and chemical regeneration.s
How do soft silicone rubber print?
- Replace the thermal grease (thermal paste) and mica (insulation) products two yuan of cooling system. The thermal conductivity of this product is 0.5-5.0W/mK, while the thermal conductivity of air is only 0.03w/mk. The resistance to breakdown is above 3000 volts, and insulation requirements can be used in most electronic devices.s
How can there be a crack in the rubber ring?
- Problems in production:1) formulation design, oil or resin less material or caused by excessive or high temperature, poor liquidity and other reasons!2) when manufacturing, the product appears the hole which the exhaust is not good3) the raw material is too thick during production, and cracks are also caused.s
What's the difference between natural rubber and three yuan ethylene propylene rubber?
- The main use of natural rubber natural rubber because of its insulation, plasticity, water vapor barrier, tensile and wear characteristics of strong elasticity and good, widely used in industry, agriculture, national defense, traffic, transportation, machinery manufacturing, medical and health fields and daily life, such as transportation with the tire industry; with the transport belt, transmission belt, sealing rings; medical gloves, transfusion tube; used in the daily life of the shoes, raincoats, warm water bag are rubber as the main raw materials manufacturing, defense on the use of aircraft, artillery, tanks, and cutting-edge technology in the field of rockets, satellites, spacecraft, space shuttle requires a large amount of rubber parts.s
Explain why butyl rubber is more resistant to oxidation and aging than other elastomers, such as natural rubber
- The macromolecular structure unit of natural rubber is isoprene, and the macromolecular chain is mainly composed of CIS -1, 4 polyisoprene. NR is the mechanical and processability comprehensive properties of all rubberss
What is rubber made of?
- High elastic polymer compound. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber, tree, rubber, grass and other plants. The synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life.s
Natural rubber, general rubber, synthetic rubber. Are these all rubber products?
- Not rubber products, rubber classification, rubber is divided into natural and synthetic rubber, synthetic rubber and general rubber and special rubber! The so-called rubber products refers to the use of rubber as raw materials to produce products, such as tires, belts, conveyor belts and so on.s
