FAQ

How to test the abrasion resistance of rubber?
It is mainly divided into two kinds of natural rubber and synthetic rubber. Natural rubber is made from rubber, rubber and grass. Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life. It has a wide range of uses. [1] can also be divided into rubber with natural rubber, general rubber, styrene butadiene rubber, nitrile rubber, silicone rubber, butadiene rubber, butyl rubber, EPDM rubber, chloroprene rubber types.
Is vulcanized sole good or rubber sole is good?
Rubber base, vulcanized bottom are basically the same, rubber vulcanization is only the process of shoe-making, rubber is the bottom of the way vulcanized and uppers together, it is more difficult to open
How can the frictional properties of rubber improve?
The free energy of rubber surface determines the size of the interaction force between rubber and duality, and then affects the adhesive friction of rubber. Generally speaking, the friction coefficient increases with the increase of surface free energy.
What is the temperature of ordinary silicone rubber resistant to low temperature?
Because the molecular structure of silicone rubber is amorphous, the temperature has little influence on its properties, and it has good cold resistance. The brittleness temperature of the general organic rubber is from -20 DEG C to -30 DEG C, while the brittleness temperature of the general silicone rubber is between -60 and -70 degrees centigrade. When the rubber is introduced in 7.5 (mol)% phenyl, brittle temperature of silicone rubber can be reduced to -115 DEG C, remain elastic at -90 DEG C and can use.
How much is the recipe for Buddha's rubber?
Rubber products were analyzed by infrared spectroscopy (FTIR), nuclear magnetic resonance (1H, NMR), mass spectrometry (MS), X diffraction analysis (XRD), ICP-MS, X fluorescence spectrometry, ion chromatography analysis, and other means. Through these testing methods can be a good solution for rubber products formulations, rubber products in the role of a detailed understanding of the more convenient for each enterprise research and development, grasp the market dynamics.
How to make white rubber products do not yellow or delay yellowing time?
Then aging is divided into thermal aging, oxygen aging, ozone (electrostatic belongs to ozone, because static electricity produces ozone). Gas corrosion aging, heavy metals, oxidation aging. Reaction aging. UV aging and so on.
What kind of product is suitable for rubber trimmer? Where's the rubber trimmer?
Generally used for metal strip trimming, that is, after the strip of metal strips with a fixed tool to remove burr or chamfer on both sides of the required radian,Scope of application: used in tableware, stationery, hardware, sheet metal and other special equipment industry.Main functions: grinding and polishing of double sides of roll beltApplicable materials: stainless steel, copper strip, aluminum belt and other metal coil.It has the advantages of rough grinding, fine grinding and polishing. It is suitable for grinding the bevel and straight edges of metal belts of different sizes and thicknesses, and is equipped with grinding wheels and spare grinding wheels. The grinding wheel has the advantages of long service life, regular forming rules and high efficiency.
Rubber products are not allowed to touch oil products, but why can rubber gloves be contacted daily? What's the point?
Contact every day is not every day inside the bubble, the contact time is short, the impact on rubber is very small.Raw rubber rubber products are: natural rubber, isoprene rubber, nitrile rubber, EPDM rubber, polybutadiene rubber, styrene butadiene rubber, polyurethane rubber, chloroprene rubber, silica gel etc.
