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: The catalyst before and after the reaction of the quality and nature of the same, does it mean that a little catalyst can be all the substrate reaction? Such as: one gram of MnO2 can reflect the infinite H2O2?
- Catalyst before and after the reaction of the same quality,
- 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: how could scientists know the exact catalyst for every reactions??? THANX sooo much
- 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 is the microcosmic principle of the catalytic reaction in the chemical reaction?
- It is actually directly involved in the reaction, but, after the reaction, it has become a product out, the equivalent of no response
- Q: Explain how a catalyst may increase the rate of chemical reaction?
- Lowers the activation energy of the reaction. Like a hill, it makes the hill lower so the reaction can proceed faster and at lower temps. Delta G is lowered. Meaning less energy is needed to move the reaction forward. Catalysts (enzymes) are substrate specific. only specified compounds like a right glove only fits a right hand and not the left hand.
- Q: Chemical catalyst in several ways
- Some are composed of oxidative - reduced electricity, such as manganese dioxide catalyzed by hydrogen peroxide decomposition
- Q: Can manganese dioxide be used as a catalyst for various chemical reactions?
- he catalyst does not participate in the reaction, such as on the platinum - rhodium alloy network, nitrogen and hydrogen reaction to produce ammonia .Piplatin - rhodium alloy network in the process of providing electrons (or similar effects, the specific is not clear, but does not react itself), the reaction Before and after the platinum - rhodium alloy network shape has not changed.
- Q: High school stage which organic chemical reactions do not use catalyst
- Aldehyde and silver ammonia solution reaction, and the new system of Cu (OH) 2 reaction.
- Q: Is there a catalyst for a chemical reaction?
- There may be many, but some of the catalytic effect of the catalyst is good, and perhaps some of the catalyst has not been found
- Q: What kind of compounds or elements can be used as catalysts in high school chemistry? What is the catalyst for what?
- Manganese dioxide and iron are more common, vanadium oxide sometimes encountered, sulfuric acid is also a catalyst, but generally used as a dehydrating agent. Inorganic catalysts catalyze the object is diverse, unlike the organic catalyst as a single, so hard to say. In high school is probably used to prepare oxygen when the use of manganese dioxide
