Product Description:

Carbon Black N220 (Granule)

Product Description:

carbon black N220:
1.Usage Rubber Auxiliary Agents;
2.Product Status:Black powder or granular;
3.Standard: ISO 9001:2000

Suggest for Use:


(1) uses for the truck tire, passenger tire tread rubber, etc., and require high strength, high wear-resistant rubber products, such as high-strength conveyor belt, industrial rubber products.
(2) The usage and for the FDA applies to all kinds of rubber, carbon black, compared with the N330, with N220 carbon black in rubber wear resistance is higher 10% to 20%, will provide the high tensile strength of rubber and tear strength, and to a certain degree of conductivity, but high heat and hardness

Q:Pls help me define a catalyst.?
catalyst is a substance which increases or decreases the rate of recation without being involve in the reaction
Q:what is the role of a catalyst in a chemical reaction?
A catalyst is used to speed up a chemical reaction. It is not consumed during the reaction.
Q:What chemical reactions can water do the catalyst?
Many solid and solid reactions can be converted into reactions between liquids, which speeds up the reaction rate, and perhaps the water here is the catalyst.
Q:What is the relationship between the chemical reaction rate and the number of activated molecules?
Nothing to do, but with the percentage of activated molecules, is proportional to
Q:Why are enzymes classified as organic catalysts?
since enzymes are found in the body,earlier they were belived to be related to life processes. however the organic molecules can also be produced outside the body through inorganic processes. a catalyst helps in speeding up the reaction.here the enzymes play as catylyst in the body for various metabolic pathways.
Q:What is the difference between a catalyst and an inducer in a chemical reaction?
The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
Q:Horseradish enzyme catalyzed Luminol chemiluminescence reaction
Disinfectant ah ~ bleach ah ~ ~ take this kind of thing to wash the blood once something can interfere with Lumino identification. So that want to do bad things must be a good plan. Lumino in the presence of copper, copper alloy, horseradish or some bleach in the presence of fluorescence. So if the scene of the crime was bleached
Q:How does catalyst aid a chemical reaction?
it makes the reaction go faster.
Q:catalyst and reagents ???
Believe me, nema, there's no way that we chemists know the best catalyst for every reaction. That would be simply impossible. However, from the type of reaction, the reactants, products, reaction conditions, solvents, etc. and from one's experience and the literature (papers and patents) one can get a good idea for most reactions of the type of catalyst that has worked for similar systems. One then starts off with a catalyst from the literature and modifies or changes it if improvement is needed based on chemical principles that one learns. There are also some theoretical calculations that can be made. Sometimes they work and sometimes they don't :) If it is an industrially important process like the Haber process for making ammonia from nitrogen gas and hydrogen gas, there may be thousands of catalysts which have been tried and evaluated. New minor improvements are being made every day. When a company does find a very good catalyst for an important reaction, often they keep it a trade secret. The good catalyst can make a huge difference in how commercially successful a particular process is. That's a large part of what chemical engineers do. You may never know if you have the best catalyst. The most you can hope for is one that is good enough. So it's a few parts personal knowledge, a few parts literature, a couple of parts theory, a lot of experimentation and often, more than not, a little luck. :)
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.
