Product Description:

  1. Product Description 

Carbon black is produced with high pure acetylene, which made from calcium carbide method.

 

Carbon black  is made by the controlled combustion of acetylene in air under pressure.

 

It is characterized by the highest degree of aggregation and crystallization orientation when compared with all types of carbon black.

 

It has high iodine absorption, effective conductivity and steady chemical performance. It is not easy to react with acid, alkali and water and is an excellent raw material for battery, conductive rubber, plastic, cable, etc

Q:How many kinds of hardness are indicated in rubber materials?
According to the hardness of the test material, three different scales are used to represent the hardness:HRA: the hardness obtained by means of 60kg load and diamond cone press. Used for extremely hard materials.HRB: the hardness of the steel ball, which is hardened by 100kg load and 1.58mm diameter, is applied to the material with lower hardness. HRC: the hardness obtained by means of a 150kg load and a diamond cone press. Used of materials of high hardness.The Vivtorinox hardness tester press the diamond square cone press in the load of 120kg and the vertex angle is 136 degrees, press the surface of the material, and the surface product of the indentation dent is divided by the load value, that is, the Vivtorinox hardness HV value (kgf/mm2).
Q:Rubber, nylon, chemical raw materials are divided into several categories?What kind of material is the automobile tyre?
The skeleton material is the reinforcing material of the main force part of tire, carcass and buffer layer (band layer), and its performance has important influence on the mechanical properties and service life of the tire.
Q:What can abrasion material be applied to rubber pipes?
Neoprene: it is an excellent universal rubber with excellent mechanical properties and chemical resistance. The utility model is suitable for preparing soft printing rubber rolls, photographic concave plates, printing rubber rolls, etc.. Polyurethane rubber: it has outstanding tensile strength, abrasion resistance and crack resistance. Poly acetate polyurethane rubber has good resistance to various solvents.
Q:Plastic, synthetic rubber, synthetic fiber is synthetic polymer material?
Polymeric materials: materials based on macromolecular compounds. Polymer materials are composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer matrix composites. Polymers are the form of life. All living matter can be regarded as a collection of polymers.
Q:What is silicone foam material for?
Silicone rubber foam material: flexible rubber products such as insoles, shoulder pads, patches and antiskid pads.
Q:What are the black O sealing rings used on the faucet? Are they poisonous?
Large manufacturers need good sealing, graphite material is used, and the use of a long time without rust!
Q:Which material has the most slippery soles?
At present, the soles of the shoes can be divided into 6 categories, namely, RB bottom, TPR bottom, PR bottom, MD bottom, PVC bottom and some mixed material soles.
Q:Do the rubber mold steel mold and what material good, now with Luo No. 12 steel sticking seriously?
There is no relationship between the die and the steel used in the rubber mould, but the formula of the rubber mixture should be adjusted mainly.
Q:What is the raw material of artificial natural rubber?
Tapioca, American rubber, India fig, African cane gum and Brazil trefoil rubber. But it has the advantages of high yield, good quality, long gum production period, low cost of making rubber and convenient processing. It is only one kind of Brazil trefoil rubber. Its yield has accounted for more than 99% of the total output of natural rubber. Made from synthetic rubber.
Q:What kind of material does the shockproof rubber cushion usually choose?
Recommend the use of EPDM, its good elasticity, although lower than natural rubber, isoprene rubber and butadiene rubber but its resistance to aging, corrosion resistance, chemical resistance, resistance to high pressure steam performance advantage, so compared to choose EPDM.Shock absorbing rubber used to be the only adhesive for NR in the past. In recent years, in order to meet the requirements of increasing heat resistance and oil resistance of automobiles, IIR, EPDM, NBR and CR have also begun to be used, and even microcellular PU elastomers and TPE thermoplastic elastomers have appeared. In addition, according to automotive requirements, in order to achieve lightweight targets, plastics have begun to replace metal, so-called rubber and plastic shock absorption rubber products.The shore hardness of ethylene propylene rubber vulcanizate is about 25-95A
