Q:What is a rubber accelerator? What role?

Usage: This product is a kind of accelerator for chloroprene rubber, chlorinated polyvinyl chloride rubber, epichlorohydrin rubber and polyacrylate rubber. The utility model is suitable for metal oxide as a vulcanizing agent, especially when Magnesium Oxide and Zinc Oxide are used as vulcanizing agents. Safe operation, not easy to burn. This product is especially suitable for 54-1 (W) and general GN chloroprene rubber. It is easy to disperse, no pollution and no discoloration in the rubber. In the general product, the dosage is 0.25-1.5, in the 54-1 (W) chloroprene waterproof product, the dosage is 0.2-0.5 parts, and should be accompanied by 10-20 parts of lead oxide.Packaging and storage of 25Kg plastic paper composite bag, kraft paper bag or plastic container. Store in a cool, dry and airy place. Avoid the sun.

Q:What is the relationship between the hardness and tensile strength of rubber pad?

The relationship between the hardness and tensile strength of rubber pad: the higher the hardness, the greater the tensile strength.

Q:Excuse me, is PU one kind of silicone? Or what is the connection between the two?

Silica gel (Silica gel; Silica) alias: silicone rubber is a highly active adsorption material, belongs to amorphous material, its chemical formula is mSiO2. NH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemical stability, in addition to strong alkali and hydrofluoric acid, do not react with any substance. Different types of silica gel have different microporous structures because of their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics which are difficult to be replaced by other similar materials: high adsorption properties, good thermal stability, stable chemical properties, high mechanical strength, etc.. According to the size of the pore size, silica gel is divided into large pore silica gel, coarse pore silica gel, B type silica gel and pore silica gel.

Q:Is sandal rubber bottom good or polyurethane good?

Rubber material itself poor ventilation, long wearing easily lead to beriberi. And summer rains, if the rain does not drain, will add story.

Q:What is rubber material?

The word "rubber" comes from the Indian language "cau-uchu", meaning "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process. In 1770, British chemist J. Priestley discovered that rubber could be used to erase pencil writing. The material used at that time was called rubber, which has been used so far

Q:How can there be a crack in the rubber ring?

Suggest:1, processing aids (stearic acid, paraffin wax or high molecular wax) increased appropriately!2, operating oil appropriate two plus -5 copies!3. Proper curing temperature. Select according to rheometer!4. Re adjust the parameters of the processed species (such as temperature, exhaust, material thickness, etc.)

Q:What kind of materials should be used for rubber products to keep the brightness of the mirror for a long time?

It is important to use recycled material as a high light material. If the selected material is not available, then it is not effective. It must be pure, only ABS.PMMA, or PC/ABS. There is material, it is best not to contain white material, mottled with a little transparent, is the best.

Q:What are the causes of fracture in rubber products?

If there is a fracture after production, it is necessary to consider whether or not the method of forming plastic material is unreasonable and where there is no improvement. Finally, it is reasonable to observe whether the structure of the grinding tools is reasonable.

Q:How can the rubber shoes be dyed?

The rubber material of the shoe edge was stained with a soft brush gently on top with a little toothpaste. The fluoride contained in toothpaste is a good cleaning detergent.

Q: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.
