FAQ
- The action of various ingredients in rubber formula
- Performance system: reinforcing agent, colorant, foaming agent, fragrance agent, hardening agent, plasticizer, flame retardant, antistatic agent
- What kind of rubber products are expensive?
- Other technologies, processes, and logistics all determine the cost
- Half finished rubber film surface white is going on
- Because inside the rubber compounding agent reachsupersaturation, rubber compounding agent near surface precipitates first, then from the inner to the surface migration of precipitation when complexing agent in the rubber to reduce its saturated state, precipitation process ended. Causes the complexing agent to achieve the supersaturation state, causes the rubber spraying frost the main reason to have: the rubber formula design is improper, the craft operation is not proper, the raw material quality fluctuates, the storage condition is poor, the product owes sulfur, the product aging and so on.
- What are the causes of the rubber products breach?
- Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.
- What is a rubber accelerator? What role?
- Thiofide ETU (Na-22), Thiofide DETU, Thiofide ZDC (EZ), Thiofide ZDMC (PZ) Thiofide ZDBC (BZ), Thiofide ZMBT (MZ), Thiofide TMTM, Thiofide MBT (M), Thiofide MBTS (DM)
- Is silicone good or rubber good?
- I don't know. Do you mean the original inorganic silica gel (not rubber) or organic silica gel?. Rubber is especially large, and silicone rubber (organic silica gel) belongs to rubber.
- How can there be a crack in the rubber ring?
- In use, high temperature and exposure to sunlight in the air can cause aging and cracking of NBR
- What is the difference between rubber expansion joint and rubber joint?
- It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into single sphere, double sphere and curved sphere. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint. This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems. Rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The product uses rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance etc., using polyester cord fabric skew high strength, strong stability and the hot and cold composite, after high pressure, mold temperature and curing. As the rubber joint has good comprehensive performance, it mainly acts as shock absorption, noise elimination and noise reduction. Therefore, it is widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, freezing, sanitation, plumbing, fire fighting, power and other infrastructure projects.
