FAQ

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.
What material is the rubber used in the tires?
Natural rubber (NR) is a kind of natural polymer with CIS -1, 4- polyisoprene as the main component, the molecular formula is n (C5H8), the composition of 91% ~ 94% is rubber hydrocarbon (CIS -1, 4- polyisoprene), the protein, fatty acid, carbohydrate, ash and other non rubber substances. Natural rubber is the most widely used universal rubber.Polybutadiene rubber is cis polybutadiene rubber -1,4-, its molecular formula is n (C4H6). Polybutadiene rubber is synthetic rubber regular structure formed by the polymerization of butadiene, the CIS content of more than 95%. According to the different catalysts can be divided into nickel, cobalt, titanium and rare earth polybutadiene rubber (nd). Polybutadiene rubber is the second largest after the synthetic rubber sbr. Compared with natural rubber and styrene butadiene rubber, it is especially excellent in cold resistance, wear resistance and elasticity after vulcanization. It has less heat under the dynamic load and has good aging resistance. It is easy to use with natural rubber, chloroprene rubber or nitrile rubber. Polybutadiene rubber is especially suitable for the manufacture of automobile tires and cold products, also can produce cushioning materials and various rubber, adhesive tape, adhesive tape and sponge etc.
What's the difference between silicone rubber and 703.704 glue?
704, temperature range of -50-250, better temperature effect, mainly used for sealing electric heating devices; electric plug sealing; instrument, instrument bonding and sealing.
What about the smell of smoked rubber products?
The curing agent and accelerator taste, rubber itself is tasteless, sulfur curing agent debris less is better, if no sulfur, with peroxide. Oil will also produce a flavor, rubber Odor Remover can be removed, in fact, that is, some spices, oh!Now there is a special rubber deodorant in the market, you may as well try.Can buy some activated carbon in the box, the cost is not high, but also long lasting odor.
How does rubber mobile phone cover change yellow?
Rubber aging process often accompanied by some significant phenomena, such as the appearance of natural rubber can be found in long-term storage of soft, sticky, spots; rubber deformation, brittle, hard, cracking, mildew, loss of light and color change.
Is polyurethane and polyurethane rubber one thing?
The biggest difference between the plastic and the rubber is the performance of the plastic properties of high tensile strength, but low toughness, toughness and rubber are relatively high, mainly related to the glass transition temperature of material, high glass transition temperature of plastics, because of its high hardness, low toughness.
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.
What solvent is used to clear the melted rubber layer?
Remove the melted rubber layer with chloroform or toluene solvent.Rubber is a latex made from rubber, tree, rubber, and grass. It is made of flexible, insulating, impermeable and air. High elastic polymer compound. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber, tree, rubber, grass and other plants. The synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life.
