Product Description:

Carbon Black N339 (Granule)

Product Description:

carbon black N339:
1.Usage Rubber Auxiliary Agents;
2.Product Status:Black powder or granular;
3.Standard: ISO 9001:2000

Suggest for Use:

(1) use for passenger tires, the card tire tread rubber, rubber conveyor belt covers, hose, and the various requirements of high abrasion resistance rubber industrial products.
(2) The usage and for the FDA in the tread rubber compound reinforced performance, abrasion resistance and tear properties of population growth near N220 carbon black, squeeze better performance, especially for SBR / BR Rubber and use system. However, the FDA manufacturing tread rubber, its rolling resistance in the N330 series carbon black is the highest, which is in the rubber formula design, must be given.

Q:Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction
CO2 + H2 = CO + H2O (conditions: catalyst, generally already heating, and reversible)
Q:how does the catalyst work (to speed up the reaction)??
Catalysts reduces the activation energy needed for a reaction, that is the energy each atom needed to have in order to have an reaction.
Q:In chemistry what is a catalyst and an example?
A catalyst is a liquid or a gas you can add to a substance to make it react quicker and/or upon itself or another chemical. A catalyst can be one chemical you add to another that causes a significant reaction or they could be variables in an experiment (like temperature) can be a catalyst. It could also be a liquid/gas that you add to a substance to neutralize it or make it safe to clean/touch/handle. For instance if you spill chemicals in a biology lab, you have to add a catalyst (generally water or clarifying soap) to make it safe to clean up. Hope I could help.
Q:How does the chemical equation calculate the quality of the catalyst?
So the reactant mass is equal to the quality of the product, with the quality of conservation
Q:What are the characteristics of the catalyst in the catalytic reaction?
The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
Q:What are the differences between biological catalysts and chemical catalysts?
One occurs in biological systems and the other is in chemical reactions. Biological catalysts are basically enzymes - proteins which regulate biochemical reactions whilst chemical catalysts act on non-biological chemical reactions and are inorganic elements or compounds.
Q:What is the difference between biological enzymes and chemical catalysts?
The biological enzyme is a class of molecules with moderate molecular weight in the living cells. It is a natural macromolecule catalyst in nature because the enzyme and the reactants are more specific than the reaction of the catalyst with the chemical synthesis of the catalyst (1) High efficiency (2) selectivity good by-product less (3) mild reaction conditions and so on
Q:Comparison of biocatalysts with chemical catalysts!
biocatalyst activity is adjustable, can be subject to hormones and other active regulation of hormones.
Q:Will the catalyst change the reaction rate in the chemical reaction?
Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
Q:Chemical catalyst
Catalyst before and after the reaction of the same quality,
