Specifications

White carbon black
1.improve the tensile strength of rubber
2.good reinforcing performance
3.high wear resistance

1.Introduction:

White Carbon Black(Precipitated silica) with special physic-chemical properties, work as reinforcing transparent fillers highly valued in formulation of rubber-based blends. They lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, They reduce consumption of rubbers and therefore reduce the cost.

2.Application:

It is widely used in silicon rubber, constrction sealant, coating, rubber, shoes, medicine, resin processing, printing ink and other industries.
1) Silicon Rubber: Improves silicon rubbers durability, rebound rate, and anti-distortion performance.
2) Plastics Industry: Improves plastic s tenacity, strength and prevents water absorption.
3) Coating Industry: Prevents agglomeration and drip. Thixotropic  additives. Increase denseness and smoothness of paint.
4) Medicine Industry: Increase denseness ,floating , carrying function in medicine. It also can be used as the pesticide powder and anti-agglomeration.

3.Features:

1) Good activity and the absorption rate.
2) High reinforcing effect and chemical stability.
3) Porous surface area.
4) Good dispersibility.

Q:What is catalyst in Science?
not all catalyst are enzymes. There are biological catalysts as well as non biological ones catalysts are something that speeds up the rate of a chemical reaction without itself getting altered after it. for example an enzyme is a catalyst because it speed up the rate of food digestion (by breaking down food molecules) and doesn't get altered after the reaction.
Q:What is positive and negative catalyst in chemistry?
Negative catalysts are, on the other hand, slowing down the positive reaction rate at the same time
Q:Is the catalyst in the field of inorganic chemistry?
In the chemical discipline, including inorganic chemistry, analytical chemistry, organic chemistry and physical chemistry and other secondary disciplines, catalytic science for the three disciplines, generally attributed to the physical chemistry of the mouth.
Q:MnO2: catalyst?
A catalyst changes the RATE of a reaction, not the products. So, yes, you get the same products without the catalyst as you do with the catalyst.
Q:When you write a chemical equation, how do you want to add "catalyst" and "?"
This is the need for your memory, write a few times, will naturally cooked
Q:The addition of the catalyst has no effect on the chemical equilibrium of the movement
The essence of chemical equilibrium is a dynamic equilibrium. Under certain conditions, the equilibrium constant of the reaction is a certain value. The role of the catalyst is to reduce the activation energy required for the reaction, increase the number of activated molecules, and increase the number of molecules per unit time , But the positive reaction is positive for the reaction, so do not change the speed.
Q:What are the roles of enzymes (protein catalysts) in catalyzing biochemical reactions in the cell.?
To make it simple unlike the dude above me...enzymes (biological catalysts) lower the activation energy, which speeds up the reaction. EVERY reaction needs a little boost of energy--the activation energy--and enzymes lower that.
Q:Name one case in which catalyst poisoning is useful?
alkynes can react with hydrogen in the presence of a catalyst such as palladium to form alkanes, if they catalyst is poisoned you can produce alkenes instead
Q:How does catalyst aid a chemical reaction?
Catalyst just speed up the chemical reaction they don't effect the chemical reaction or its equilibrium.............
Q:describe a biological catalyst?
One of the best known biological catalyst reactions is the Fixation of Nitrogen. Biological Nitrogen Fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by a bacterial enzyme called nitrogenase. Microorganisms that fix nitrogen are called diazotrophs. The formula for BNF is: N2 + 8H+ + 8e− + 16 ATP → 2NH3 + H2 + 16ADP + 16 Pi Although ammonia (NH3) is the direct product of this reaction, it is quickly ionized to ammonium (NH4+). In free-living diazotrophs, the nitrogenase-generated ammonium is assimilated into glutamate through the glutamine synthetase/glutamate synthase pathway.
