3.Applications:

Water effluent treatment system
It's used for purification of drinking water and wastewater treatment by settling of impurities by

means of precipitation and flocculation.

Paper Industry
It helps in sizing of paper at neutral and alkaline pH, thus improving paper quality (reducing spots

and holes and improving sheet formation and strength) and sizing efficiency.

Textile Industry
It is used for color fixing in Naphthol based dyes for cotton fabric.

Other Uses
Leather tanning, lubricating compositions, fire retardants; decolorizing agent in petroleum, deodorizer; food additive; firming agent; dyeing mordant; foaming agent in firefighting foams; fireproofing cloth; catalyst; pH control; waterproofing concrete; aluminum compounds, zeolites etc.

4. Package:

Packaging Detail: PP/PE 50kg/bag;25kg/bag;Jumbo bag or according to customers' requirements.

20-25MT will be loaded in per 20'FCL container.

5. Attention and Storage:

The product is liable to absorb moisture and clot due to long-term exposure, so shady, cool and ventilated environment is needed.

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 kind of chemical reaction requires a catalyst?
For example, the system of ammonia, S02 oxidation into SO3
Q:Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
In the chemical equilibrium, after adding the catalyst, the positive and negative reaction rate increases equally, but the positive reaction rate is still equal to the reverse reaction rate, so the balance does not move
Q:What is the nature of the chemical catalyst?
The nature of the catalyst is to play a catalytic role in reducing (or increasing) the anti
Q:CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.
2CO + 2NO = catalyst = 2CO2 + N2
Q:why are catalysts never used up during reactons?
Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
Q:What are the requirements for the catalyst for the chemical industry?
Generally find a few, according to the cost and cost of cost, choose cost-effective
Q:Biological enzymes and chemical catalysts of the differences in the source
Biological enzyme catalytic reaction conditions are mild, high selectivity, can not be infected
Q:What is the effect of the catalyst in chemistry?
In fact, the catalyst in the chemical reaction is not the reaction of the role, but to play a role in accelerating the speed of chemical reaction, it is like a reaction to an hour, but joined a certain catalyst, the reaction speed A lot, as long as half an hour to react to play, the catalyst as long as properly handled, but also can be recycled, the students do not have any chemical changes
Q:What is a catalyst and how does it make a reaction go faster?
Wohoo i stil remember this from last year! A catalyst is a substance that speeds up the chemical reaction without being used up in the reaction itself e.g. manganese dioxide in the making of oxygen. And.. A catalyst works by providing a convenient surface for the reaction to occur. The reacting particles gather on the catalyst surface and 1) collide more frequently with each other 2) more of the collisions result in a reaction between particles because the catalyst can lower the activation energy for the reaction. A catalyst is often used as a powder, so that it has a bigger surface area per gram. Okay i copied the last bit from my science book but i remembered the first bit!! HA!
