- What kind of material does the shockproof rubber cushion usually choose? What's the hardness?
- Recommend the use of EPDM, its good elasticity, although lower than natural rubber, isoprene rubber and butadiene rubber but its resistance to aging, corrosion resistance, chemical resistance, resistance to high pressure steam performance advantage, so compared to choose EPDM.Shock absorbing rubber used to be the only adhesive for NR in the past. In recent years, in order to meet the requirements of increasing heat resistance and oil resistance of automobiles, IIR, EPDM, NBR and CR have also begun to be used, and even microcellular PU elastomers and TPE thermoplastic elastomers have appeared. In addition, according to automotive requirements, in order to achieve lightweight targets, plastics have begun to replace metal, so-called rubber and plastic shock absorption rubber products.
- What does the rubber tire do to people?
- Rubber is an elastic polymer. Rubber can be obtained from the plant sap, can also be man-made, both have many applications and products, such as tires, washers, etc., has become an important economic crop. The cultivation of rubber is mainly concentrated in Southeast Asia, such as Thailand, Malaysia and Indonesia.
- What are the hazards of waste rubber and how can they be used for regeneration?
- The disposal of waste rubber is one of the serious problems facing people today. In order to meet the requirements of materials to improve the performance of rubber, towards high strength, wear resistance, stability and aging resistance of the direction of development, but also caused a long period of rubber not biodegradable waste after a large number of waste rubber, causing than plastic pollution (white pollution) more difficult to deal with the black pollution. On the other hand, precious rubber resources are wasted.
- How to distinguish between good and bad silicone rubber gasket?
- When the silica gel products are subjected to alternating stress (or strain), the structure and properties of the material change. With the development of fatigue process, the failure of silica gel products is called fatigue damage. Therefore, fatigue is also a way to distinguish the quality of silicone products.
- Is there any poison in the processing and testing of rubber products? What about the salary?
- There will be some flavor at the time of processing, as well as some fillers, oil will be a little toxic, and some crosslinking agents may be toxic. But now the mixer extruder is mostly closed, so it is common to pay attention to respiratory protection.A mechanical test is usually less toxic, and a glove is enough.If you do thermal testing, such as TGA, DMA, DSC and so on, it will degrade and release small molecules, especially if the aromatic oil is filled, be sure to pay attention to.
- What are the bridge rubber air bags used for?
- Open the valve, inflated to the specified pressure, you can close the valve, must not exceed the pressure.
- Rubber products labeled Huai gum can improve wear?
- Basically through the carbon black to adjust, carbon black will also be divided into a variety of, according to the degree of wear resistance will also be divided into many grades, in the rubber formula has reinforcing effect.
- What is rubber material?
- Rubber (Rubber): highly elastic polymeric material with reversible deformation. 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.
