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: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.

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 are the causes of fracture in rubber products?

Rubber products appear broken phenomenon, mainly for the following reasons:1, rubber products for a long time led to the phenomenon of fracture;2, too tired lead to rubber products broken;3, long-term exposure to ultraviolet light will cause rubber products broken;4, in the production of the use of chemical additives and materials conflict, resulting in incompatible and broken;5, the production process, the release of time is not appropriate, resulting in fracture (such as scratches);6, abrasive structure is irrational, lead to fracture;7, the use of materials is irrational, leading to fracture is also common;8, materials placed too long, in use, resulting in broken products, resulting in waste.

Q:What are the uses of rubber oil?

Application: mainly used as rubber softener. The effect of carbon black rubber products: rubber materials have good dispersing effect of softening rubber, increase the viscosity, make the rubber soft and smooth, and can improve the anti corrosion performance of coke products cold, another of the thiazole accelerator can increase the activation effect of complexing agent

Q:How can rubber products be softened?

Rubber softener for fluid or semi fluid, dangerous goods, should be stored in the rain (the most important) ventilation dry place shading.A package (drums, plastic barrels, plastic bags), according to the needs of the customer.

Q:What do you pay attention to when using rubber?

The greater the polarity of the rubber, the better the bonding effect. Among them, nitrile butadiene chloroprene rubber is of great polarity and strong adhesive strength. Natural rubber, silicone rubber and isobutyl rubber have less polarity and weak cohesive force. In addition, the rubber surface often has the release agent or other free out auxiliaries, hinders the adhesive effect.Adhesive is used to connect rubber, and the concrete methods are divided into hot sticking method and cold sticking method.Hot sticking method is realized by adhesive plastication of unvulcanized rubber and glued rubber together after curing, the method is complicated, need to heating and pressurizing equipment, inconvenient to use.Cold adhesive method is to apply the adhesive to the surface of the glued product. After airing, fold it and solidify it at room temperature. Of course, proper heating can shorten the curing time and increase the bonding strength. Cold sticking method is simple and energy saving. It is a good method to be popularized.

Q:What is the tensile strength of silicone rubber?

Silicone rubber is a kind of elastomer with molecular backbone, -Si-O- inorganic structure and side group as organic group. Silicone rubber is a semi inorganic, saturated, mixed, non-polar elastomer.

Q:What is the relationship between synthetic rubber and crude oil?

Synthetic rubber material also has excellent heat resistance, cold resistance, corrosion resistance, and little affected by environmental factors, synthetic rubber materials and suitable for 60 to 250 degrees below zero normal use.

Q:What kind of material does the shockproof rubber cushion usually choose? What's the hardness?

Of course is to choose butadiene rubberThe biggest characteristic is the molecular structure, mainly for the CIS structure, so the elasticity, cracking resistance and dynamic performance is excellent, and the rubber pad shock proof function is guaranteed, and the rubber cushion life is guaranteed, and the hardness is about 55.
