Product Description:

                                        Precipitated Silica

Product Description:

Precipitated Silica
1.Used in tires, tire body, with beam layer and sidewall rubber and rubber products,Shoes Etc.

2.Product Status:White powder

Suggest for Use:

(1) M160 Used in tires, tire body, with beam layer and sidewall rubber and rubber products.For strengthening filler in rubber, rubber formula provides high hardness, high breaking strength, high tear strength and high wear resistance, improve the rubber and steel cord bonding strength. Improve the durability of the rubber, to improve flexible and shock resistance, resistance to improve tractional snow tires on the road, improve the tire all-weather performance.

(2) M170 Used in tires, rubber products and sole material.For strengthening filler in rubber, rubber formula provides high hardness, high breaking strength, high tear strength and high wear resistance, and resistance to aging performance.

(3) M180 Used in shoe materials, rubber products. For strengthening filler in rubber, in color rubber products, instead of reinforcing carbon black, meet the needs of white or translucent product, it has strong bonding strength, tear resistance and heat-resistant anti-aging performance.

Q:why is palladium/platinum a good catalyst?
Palladium and platinum are good catalysts because they _adsorb_ certain molecules, especially gases. Adsorption is NOT the same as _absorption_. Adsorption is a process by which a chemical (gases or liquid) physically becomes attached to the _surface_ of an adsorbate (a solid). Once gas molecules are adsorbed on the surface of a catalyst, they are much nearer each other and more likely to react. Absorption is a process by which a gas or liquid is incorporated throughout the volume of an absorbate (a solid), rather than just on the surface. The fact the palladium happens to _absorb_ hydrogen molecules well probably has little to do with its function as a catalyst and is probably just a coincidence. In fact, two of the main reactions in a catalytic converter don't involve molecules with hydrogen atoms at all. On the other hand, WHY platinum and palladium are good catalysts are a mystery. Presumably, they are good at enhancing the Van der Waals forces that cause adsorption with other molecules, but WHY the platinum family of metals do this better than other metals is not fully understood (I don't think).
Q:Can manganese dioxide be used as a catalyst for various chemical reactions?
Catalyst in the reaction process involved in the reaction, after the completion of the reaction was reduced to the original ingredients.For example: heating decomposition of potassium permanganate when added potassium permanganate potassium potassium permanganate decomposition process, the potassium permanganate is involved in the reaction, The specific way is not clear.Finally, the occurrence of potassium permanganate before and after the reaction of the catalyst changes in morphology, particles into powder, powder particles and so on.
Q:A catalyst elevates the rate of a reaction by?
Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier. The catalyst may increase reaction rate or selectivity, or enable the reaction at lower temperatures. This effect can be illustrated with a Boltzmann distribution and energy profile diagram. Take a look!
Q:Catalyst & an exothermic reaction?
A catalyst by its very nature increases the rate of reaction by binding to a reactant, hence changing its shape and reactivity with other reactants. However, the catalyst is neither consumed nor will it change the chemical shape of the products.
Q:Chemical common sense about the catalyst
In order to speed up the absorption, speed up the reaction rate
Q:Can a catalyst react with a reactant?
it can react to start the reaction but should be regenerated during the reaction. if it reacts and not regenerated,then its better to call it reactant instead of catalyst
Q:What is the PTC catalyst in chemistry?
1, polyether chain polyethylene glycol: H (OCH2CH2) nOH chain polyethylene glycol dialkyl ether: R (OCH2CH2) nOR2, cyclic crown ethers: 18 crown 6,15 crown 5, Fine and so on. 3, quaternary ammonium salt: commonly used quaternary ammonium salt phase transfer catalyst is benzyl triethyl ammonium chloride (TEBA), tetrabutyl ammonium bromide, tetrabutylammonium chloride, tetrabutylammonium hydrogen sulfate (TBAB) , Trioctylmethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, and the like. 4, tertiary amine: R4N X, pyridine, tributylamine and the like. 5, quaternary ammonium base (its alkaline and sodium hydroxide similar) soluble in water, strong hygroscopicity. 6, quaternary phosphonium
Q:What about the chemical reaction of the catalyst if there is no catalyst?
Slow response or no reaction
Q:What is the difference between a catalyst and an oxidizing agent?
A catalyst is a substance that increases a chemical reaction rate without being consumed in the reaction. Heat is probably the most common catalyst. In some cases the reaction will occur without the catalyst but very slowly. In other cases, the reaction will not occur. In the body, enzymes are often catalysts. An oxidizing agent, causes a compound to lose electrons and it is then said that that compound was oxidized. The oxidizing agent gains electrons and is said to be reduced. An example is hydrochloric acid. Is is oxidized by oxygen gas and loses hydrogen atoms leaving chlorine gas. The oxygen gains hydrogen atoms and forms water. The hydrochloric acid is oxidized and the oxygen is reduced.
Q:What is the role of the catalyst in chemical knowledge?
Reduce or increase the energy required for the reaction, can also slow down, do not have no effect on the reaction
