FAQ

How are rubber wires processed?
Rubber wire, mainly refers to the insulating layer and the jacket is made of natural rubber, styrene butadiene rubber, ethylene propylene rubber, in addition to meet the insulation properties and physical mechanical properties, aging resistance, abrasion resistance requirements, some products require oil resistant, flame retardant.
In addition to the smell of rubber?
Soil recruit: 300 grams of black tea, hot tea, two washbasin water, into the living room, and window ventilation, 48 hours, indoor formaldehyde content will fall by more than 90%, the pungent odor is basically eliminated.
How to distinguish between plastic products and rubber products, toys?
There are several ways to distinguish between plastic and rubber products:1, color: plastic products, relatively transparent color, relatively strong, and rubber products are relatively poor transparency;2, thickness: plastic product thickness than rubber products thin;3 hardness: general plastic products than rubber products slightly hard;4: texture: plastic products are more smooth or microstrip lines, and rubber products on the surface of some of the same as human skin, texture deeper or more rough;5, taste: plastic taste, the taste of micro strip plastic, and rubber products are micro rubber rubber flavor;6, weight: general plastic products will be slightly lighter than rubber products.
How to distinguish between rubber and polyvinyl chloride?
1) preparation: vinyl chloride monomer (vinyl, chloride, monomer, referred to as VCM) in peroxide, azo compounds and other initiators; or under the action of light and heat, polymerization by the principle of free radical polymerization of polymers. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins.2) properties: white powder, amorphous structure, degree of branching is small, the relative density of about 1.4, the glass transition temperature of 77~90 DEG, 170 DEG C to decompose, the stability of heat and light, at 100 DEG C or after long time exposure to sunlight, will decompose and produce hydrogen chloride, and further automatic catalytic decomposition that change, the physical and mechanical properties also decreased rapidly, in the practical application must be added in order to improve the stability of heat and light stabilizer of the.
Rubber and metal have to be sealed before they are too strong
Different materials and O-ring O-ring compression the change of general material such as NBR, NR, nitrile rubber, natural rubber, chloroprene rubber CR, EPDM three EPDM, HNBR hydrogenated nitrile rubber, silica gel SILICOME SBR Buna, styrene butadiene rubber, SBR, acrylate rubber ACM, compression O-ring or the 20% to calculate. If it is a special material FKM, VITON, PU, FLS silicon fluorine rubber, fluorine rubber, polyurethane, compression of these materials is calculated by 15% o ring.
What kind of rubber is suitable for waterproof aprons?
Typical properties of rubber material are low glass transition temperature and high elasticity. The main properties of common rubber materials are shown in the schedule after the teaching materials.
How can rubber and mould not be bonded when producing rubber products?
When rubber products are made, rubber and mould can not be bonded:1, abrasives to be polished, coating treatment, to achieve the most smooth surface and high temperature corrosion resistance requirements!2, formula design, less use of sticky, easy to corrosive materials;3, curing process should meet the requirements of formula design!
What's rubber skin?
High elasticity polymer. 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 (see photo). 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. The molecular chain of rubber can be crosslinked, and the crosslinked rubber can recover quickly when it is deformed by external force, and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of rubber industry. It is widely used in making tyres, rubber hoses, tapes, cables and other kinds of rubber products.
