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:What's the name of a soft rubber material that is resistant to high temperatures above 500 degrees?
Because it is sealed role, so generally about 300 degrees using silica gel material, if the material is good, 500 degrees oven occasionally also can. Generally 500 degrees is to use asbestos strip or high temperature cotton to seal
Q:What are cots for?
Cots are metal or other materials as the core, covered with rubber by vulcanized and made of roller shaped products. Rollers usually by outer glue, glue, hard metal core, roll neck and vent, the process comprises a roller core processing, sandblasting, adhesive glue molding, wrap cloth, wire winding, autoclave curing and surface processing process.
Q:What kind of rubber material is EPDM?
Three yuan is three yuan, a copolymer of ethylene propylene diene and non conjugated diene. With special structure, one of only two keys can be copolymerized, unsaturated double bonds in the main chain. As another unsaturated polymer backbone will not become, will become the side of the side chain. The main polymer chain three yuan is fully saturated. This characteristic makes three yuan can resist heat, light, oxygen, especially ozone. Three yuan is essentially non-polar, resistant to polar solvents and chemicals, low water absorption, good insulating properties.In the three yuan ethylene propylene production process, by changing the number of three monomers, ethylene, propylene ratio, molecular weight and its distribution, as well as vulcanization method, can adjust its characteristicsThe choice of EPDM third monomer
Q:Elastic modulus of rubber
The elastic modulus is an important performance parameter of engineering materials, from a macro perspective, the elastic modulus is a measure of the size of the object against the elastic deformation ability scale, from the microscopic point of view, it is a reflection of atoms, ions or molecules bonding strength.
Q:What is the difference between rubber sole and plastic sole? Which is better?
They are: Rubber each one has his good points is a very traditional old shoe, but the wear resistance, high temperature performance is excellent. And plastic is a new type of material, light and easy to shape.
Q:What material is silicone, please?
After the silica gel has absorbed moisture, it can be regenerated by solarization, baking and air drying.Chemical composition of silica gel desiccantSilica gel desiccant --- the main component is silica dioxide, from natural mineral by purification processing, granular or beads. As a desiccant, its pore structure (average 2A) Good affinity for water molecules. The most suitable hygroscopic environment for silica gel is room temperature (20~32) and high humidity (60~90%), which can reduce the relative humidity of the environment to about 40%.This is a absorb moisture from the atmosphere in the water, it is through the physical principle of drying the water molecule adsorbed on its structure or by chemical absorption of water molecules and change its chemical structure into another substance.Variable silica gel: used to keep the instrument and balance dry. Turn red after water absorption. The resulting silica gel can be dried and used again after regeneration. It can be dried amines, NH3, O2, N2 and so on
Q:What's the difference between the lining material and the rubber? What media are applicable?
The properties of the lining rubber are related to the rubber composition, and the medium shall be determined according to the temperature, pressure and corrosiveness of the medium. Generally applicable to acid, alkali, salt and other liquid medium transport.
Q:What's the difference between sole material MD and TPR?
TPR: thermoplastic rubber (Thermoplastic Rubber), is a kind of rubber and thermoplastic properties of materials, rubber performance and processing and recycling by thermoplastic plastics, can use ordinary plastic forming machine with injection molding, extrusion molding, blow molding type made of rubber products.
Q:What kind of rubber skid proof performance is better?
(1) natural rubber: the advantage of natural rubber is that it is very soft, elastic and good, suitable for all kinds of sports, but the disadvantage is obvious, that is, it is not wear-resistant. Indoor sports shoes are mostly made of natural rubber
Q:Rubber products (pads) appear white, just like mildew, and the ingredients are the same as before, starting in September last year,
Please ensure that the vulcanization time is long enough and that the two vulcanization time is sufficient, which will effectively improve the problem
