Use and performance
PTFE (Poly tetrafluoroethylene, abbreviated as PTFE), commonly known as "Plastic King", is a high molecular polymer made by polymerization of tetrafluoroethylene as a monomer. White waxy, translucent, excellent heat and cold resistance, can be used for a long time at -180～260ºC. This material has the characteristics of anti-acid, anti-alkali, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its coefficient of friction is extremely low, so it can be used not only for lubrication, but also as an ideal coating for the inner layer of water pipes that are easy to clean.
The high-performance PTFE materials we provide can be used in the production and processing of various seals.
- Q: How should the rubber products be dirty?
- First coated with vinegar on the top, after dry, and then wipe paper, so clean
- Q: What problems need to pay attention to when inflating the pipe?
- Pipe water blocking airbag, closed water test, sewage pipe matters are different, big air sac, small sac also have differences, in terms of sewage pipes, we need to pay attention to the following points:1, because the airbag is rubber products, so afraid of scratching, when receiving airbags, we must first test gas test to see if there are broken places. Repair and replace in time.2, carefully check instructions, rated pressure, etc..3, in the ground to connect three pressure gauge, slowly filling some gas, slowly into the pipeline.4, clean up the pipeline wall, no burr, punctured balloon.5, carefully checking the pressure meter, slow inflation, do not look at the gas, to avoid pressure gauge not timely response and the consequences of explosive charge. When the work pressure is up, stop inflating and never exceed the pressure.6. The large air bag has a handle on it and prevents it from running.
- Q: What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?
- The Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM) are approximately:Rubber elastic modulus 0.0078GPa, Poisson's ratio 0.47.
- Q: Several aspects of rubber aging performance and how to identify them
- Oxygen, oxygen free radical chain reaction in rubber with rubber molecules, the molecular chain rupture or excessive crosslinking caused by rubber performance. Oxidation is one of the important reasons for aging of rubber
- Q: For the application of common synthetic rubber, not too long or too difficult, want to do
- Isoprene rubber (IR) is a kind of structure of rubber from the CIS isoprene monomer polymerization. The chemical composition, and three-dimensional structure of natural rubber is similar to that of the performance is very close to the natural rubber, synthetic natural rubber said. It has most of the advantages of natural rubber, aging due to natural rubber elasticity and strength. Slightly lower than natural rubber, poor processing performance, high cost. Use temperature range: - 50 DEG C ~ + 100 DEG C can be used instead of natural rubber tires, rubber shoes, rubber hose, making tape and other generic products.
- Q: Natural rubber, general rubber, synthetic rubber. Are these all rubber products?
- General rubber is a big category, mainly refers to the general rubber tire manufacturing and commercial products of rubber, synthetic rubber production accounted for more than 50%, including styrene butadiene rubber, butyl rubber, EPDM rubber, chloroprene rubber etc..
- Q: The action of various ingredients in rubber formula
- Cost system: filler, compatibilizer
- Q: Why does rubber stink?
- Because of the original gum problem, such as PU or polyurethane will have a foul smell.Highly elastic polymer material with reversible deformation of rubber. 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.
- Q: What is the relationship between synthetic rubber and crude oil?
- Synthetic rubber also has disadvantages, the drawing effect of main disadvantage lies in its relatively poor, tearing strength and mechanical properties are relatively poor, but because of synthetic rubber materials than natural rubber has the advantages of low cost, but also a lot of Companies in the production of low-end products preferred.
- Q: What kind of rubber is suitable for waterproof aprons?
- The vulcanized rubber is a linear or branched structure, because of its low strength, little elasticity, hardening of the cold, softening of the heat, dissolution of the solvent, etc., which makes the products useless. Therefore, the rubber products must be vulcanized, deformed, meshed or of a shape structure to be of practical value.Proper vulcanization of the rubber can maintain the high elasticity of the rubber and the strength of the rubber. At the same time, in order to increase product hardness, strength, wear resistance and tear resistance, while adding inert filler in the process (such as Zinc Oxide, clay, chalk and barite etc.) and reinforcing filler (such as carbon black).
