Aluminum Sulfate Low Fe Qualifed Grade Manufacturer in China

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:Chemistry why the catalyst can be equal to speed up the positive reaction rate
Since the catalyst only changes the activation energy and the amount of reactivity can be reduced, the amount of reaction energy is also reduced. Therefore, a positive catalyst is also a good catalyst for its reaction. Speed up the same multiple.
Q:Co and No form a chemical equation for Co2 and No2 under the action of a catalyst
2CO + 2NO == N2 + 2CO2
Q:What is the difference between an enzyme catalyst in a living body and a catalyst in chemistry?
Enzyme has a high catalytic efficiency (high efficiency) Generally speaking, the reaction rate of the alcohol catalyzed reaction rate is 106-1013 times higher than that catalyzed by the chemical catalyst
Q:What are the methods of catalyst characterization?
Chemical means, according to the different detection methods, methods are different, but is to explain the chemical properties, chemical structure characteristics.
Q:What is the superiority of the catalyst compared to the stoichiometric reagent?
Specificity: an enzyme can only catalyze one or a class of substrates, such as proteases that catalyze the hydrolysis of proteins into polypeptides;
Q:No one knows the expression of the catalyst and the chemical expression of the acridine
If it is potassium permanganate oxygen, the catalyst is only manganese dioxide, so write on the horizontal line MnO2
Q:Is the enzyme in the enzyme bigger than gold?
A biological enzyme is equivalent to a key that opens a complex compound whose importance is that its unique structure or multidimensional shape matches a part of the group. Once these two parts are combined, the specific chemical bond in the group molecule changes as if the lock was opened. When the reaction is completed, the enzyme is released and repeated with the next group, followed by repeated repeats. Many chemical reactions in the normal temperature conditions, the reaction is very slow so that the whole process is difficult to be perceived.
Q:What is a catalyst and how does it make a reaction go faster?
Catalysts change the rate of the reaction (faster / slower) without being consumed (used up) in the reaction. They do this by providing a lower energy (easier) pathway from reactants to products. For example in the reaction A + B -D, we can split up the reaction into the two half-reactions below. The first describes the two reactants coming together and the second describes the product formation. A + B -AB AB -D If we add a catalyst which both A and B bond to easier than they do to each other this can increase the rate of the reaction by bringing A and B together on the catalyst. This can be represented with the half-equations below. A + B + Cat -ABCat ABCat -D + Cat
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:Palladium is the main catalyst in chemistry?
Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on. While the most common and most commercially available palladium jewelery is palladium.
