Q:The action of various ingredients in rubber formula

Performance system: reinforcing agent, colorant, foaming agent, fragrance agent, hardening agent, plasticizer, flame retardant, antistatic agent

Q:Why is rubber resistant to compression and wear better than metal?

The rubber bushing is made of metal and has a flexible connection. The sheath is made of rubber

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:Why should the tire be made of rubber?

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. It is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products.

Q:NR natural rubber manufacturers, who knows Guangdong here, there are manufacturers, a few hair connection is OK

Isoprene rubber (IR) is a kind of CIS structural rubber polymerized from isoprene monomer. The chemical composition and solid structure are similar to those of natural rubber, and the properties are very close to natural rubber. Therefore, synthetic rubber is called. It has most of the advantages of natural rubber, anti-aging, because of natural rubber, elasticity and strength than natural rubber slightly lower, poor processing performance, higher cost. Temperature range: about 50 DEG C ~100 can replace the natural rubber production of tires, rubber shoes, rubber hose, tape and other general products.

Q:How to make mobile phone rubber coat non stick ash?

Stained with ash is not terrible, with a period of time you can use clean water with a small amount of detergent, wash it; if the stain is very serious, you can use alcohol wipe, and then clean with water.

Q:How do rubber undergo vulcanization?

Vulcanization of rubber can be divided into three categories: cold vulcanization, room temperature vulcanization and heat vulcanization according to the curing conditions.1. Cold vulcanizing products impregnated in a solution of carbon disulfide containing 2% to 5% sulfur chloride.2, room temperature vulcanization, the use of room temperature vulcanized mortar (mixed rubber solution) for vulcanization.

Q:What is rubber leather?

Special rubber refers to rubber with some special properties. The main contents are as follows: chloroprene rubber. CR, prepared by polymerization of chloroprene. With good overall performance, oil resistance, combustion resistance, oxidation resistance and ozone resistance. But its density is larger, it is easy to crystallize at room temperature, hard to store, cold resistance is poor. Nitrile rubber. Referred to as NBR, made by copolymerization of butadiene and acrylonitrile. Good oil resistance and aging resistance. It can be used in the air of 120 degrees Celsius or in the oil at 150 degrees centigrade for a long time. In addition, it also has water resistance, air tightness and excellent adhesive properties. Silicone rubber. The backbone consists of alternating atoms of silicon and oxygen, with organic groups on silicon atoms. High and low temperature, ozone resistance, good electrical insulation. Fluorine rubber. A synthetic rubber containing fluorine atoms in the molecular structure. Usually, the number of fluorine atoms in the fluorine containing unit in the copolymer is expressed as fluorine rubber 23, and the copolymer is two vinylidene fluoride and three fluorine vinyl chloride. Fluorine rubber, high temperature, oil resistance, chemical resistance. Polysulfide rubber. Condensation of two halides with sulfides of alkali or alkaline earth metals. Has excellent oil resistance and solvent resistance, but the strength is not high, aging resistance, poor processability, odor, and more with nbr. In addition, there are polyurethane rubber, epichlorohydrin rubber, acrylic rubber and so on.

Q:What are the rubber parts for the car?

Sealing ring, toothed cutting belt, automobile synchronous belt, automobile multi wedge belt, automobile engine suspension rubber pad, shock absorber glue, anti-collision shock absorption rubber, dustproof cover, fuel tank cover, filter rubber parts, cloth (diaphragm)

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.
