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.

My company produced solid industrial aluminum sulfate is light yellow flaky solid, is self-produced high-quality bauxite head stone, sulfuric acid, non-polluting groundwater and other raw materials, pressurized reaction process refining. Is now mainly used for drinking water, industrial wastewater purification, sizing pulp paper industry, oil industry as a clarifying agent, the oil industry as a deodorant bleaching agents, leather tanning, pigment manufacture and so on. No iron sulfate, a white flaky solid aluminum for titanium dioxide post-processing, high-grade paper production and the production of catalyst and so on.

Q:What is the direction of the chemistry of the material chemistry?
Generally in the chemical plant to do engineering design engineers, the past few years, science and engineering graduates generally do not worry about work.
Q:Junior high school chemistry - chemical reaction before and after the quality and chemical properties of the material must be the catalyst?
It is not always possible that the equivalent reaction, i.e. one or more of the reactants, is the same as the relative atomic mass of one or more of the products and the coefficients in the chemical equation are the same
Q:Why are there so many catalysts?
Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically. They establish a local environment that promotes one or more chemical reactions to take place. A catalyst is important in many industrial processes. Sulfuric acid, which is used to produce batteries, detergents, dyes, explosives, plastics, and many other produces, is commonly produced using a catalyst called vanadium oxide. Ammonia, a primary component of many fertilizers, could not be produced economically without the use of iron oxide which speed up the reaction. The process of catalyst also affects the state of our global environment. Automobiles use catalytic converters to treat exhaust. The metals platinum and palladium facilitate the chemical conversion of noxious gases to more inert forms, greatly decreasing the environmental impact of combustion engines. Probably the most important impact of catalyst is on life itself. All important biochemical reactions are catalyzed by molecules called enzymes. Most enzymes are proteins which catalyze specific reactions within cells. Some examples include polymerases, which synthesize DNS and RNA, peptidases, which digest protein, and ATP synthases, which produce energy for the many different cell activities.
Q:The addition of the catalyst has no effect on the chemical equilibrium of the movement
Hello, the essence of chemical equilibrium is a dynamic equilibrium, under certain conditions, the equilibrium constant of the reaction is a certain value, the role of the catalyst is to reduce the activation energy required for the reaction, increase the number of activated molecules, so that the reaction within a unit time The number of molecules increased, but the positive reaction is positive for the reaction, so do not change the speed
Q:Chemical "catalyst can speed up the chemical reaction rate of other substances," this sentence right?
Wrong, the catalyst is divided into two kinds, one is to speed up the chemical reaction speed, and the other is the opposite
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:Copper oxide and ferric oxide can replace manganese dioxide as a catalyst in chemical reaction?
Can not. They will react
Q:Can a catalyst be present in the rate equation?
Yes, a catalyst can be included in a rate law. That's because, most reactions occur in a series of step and the rate is based on the rate determining step, which is the slowest step. A catalyst may be a reactant in the rate determining step, and a product in a subsequent step. Therefore, the catalyst is not included in the overall reaction. But a catalyst need not always be in the rate law. The rate law is usually based on the rate determining step. ========== Follow up =========== In the free response questions on the AP chemistry exam there has been at least one case where a rate law included a catalyst( 2002D). Brown and LeMay always include at least one in their examples, and I always cover this situation when I teach rate laws and mechanisms in AP chemistry. Here is one comment: Other examples of species not in the balanced reaction occurring in the rate law would include catalysis, where a catalyst does not normally appear in the balanced reaction but does appear in the rate law. www.chem.arizona.edu/~salzmanr/48... Consider this generalized reaction which is catalyzed by M A + B --C A + M --Q ... slow Q + B --C ... fast M is the catalyst, and Q is the intermediate. The slow, or rate determining step, depends only on the concentrations of A and M, the catalyst. So even though the overall reaction does not include, M, the rate law does. Rate = k[A][M]
Q:The chemical reaction equation of methanol heating and oxygen in the presence of catalyst
2CH3OH + O2 === 2HCHO + 2H2O
Q:Can chemical reaction limits be changed by catalyst or other methods?
No, the catalyst can only speed up the chemical reaction, but can not change the chemical limit.
