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:Is it possible for the different chemical reactions to have the same catalyst?
Right, think about the catalysis of biological enzymes
Q:Can some chemical reactions have a variety of catalysts that are correct or wrong?
Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy
Q:Does the catalyst affect the chemical reaction rate constant?
The catalyst will change the rate constant
Q:explain how a catalyst can affect the rate of reaction but not be in the overall equation.?
a catalyst is a substance that speeds up the rate of reactions that would already happen (the reactions are spontaneous) but would take a long long time to occur. Every reaction proceeds from a level of high energy to a lower level of energy, but in order to start going downhill you need to get up, in affect getting more energy than the reactants have now. This is because the transition state, or what the reactnat/product is in the middle of the reaction, is less stable and requires more energy than the reactants. Catalysts lower the extra energy needed (called activation energy) to a level that the reactants already have, and the reaction occurs.
Q:On the issue of chemical balance and catalyst
The catalyst can only improve the equilibrium speed, reducing the time to reach equilibrium, but will not affect the chemical balance.
Q:Chemical problems, the selection of catalysts.
Phosphoric acid or sulfuric acid, 280 to 300 ° C, 7 to 8 MPa
Q:What is the chemical vinyl chloride and benzene plus catalyst?
Looks like no ethyl benzene, it is vinyl benzene
Q:Word editor when playing chemical equation = with the above conditions or how to adjust the size of the catalyst, how to make it centered
Open the word - insert - object - WPS3.0 formula - and then select the "label arrow template", you can add a catalyst.
Q:Effect of catalysts on reaction rate??
A catalyst provides an alternative route for the reaction, (maybe more steps than previously), but each step having a lower activation energy than the original uncatalysed reaction. This means that although there will be the same number of collisions per second (if the reaction is performed at the same temperature as before), a greater fraction of those collisions will result in a reaction - so there will be more reactions per second. In the case of a heterogeneous catalyst - e.g. a solid surface the change is that the first step is a bond to the surface which waekens some of the bonds in the reactants - again making a greater fraction of reactions result in reaction.
Q:What is the definition and function of the catalyst in chemistry?
Definition: in the chemical reaction can change the chemical reaction rate of other substances, and its own quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. The role of the catalyst in the chemical reaction is called catalysis. The use of a catalyst only changes the rate of chemical reaction and does not alter the quality of the product.
