Aluminium Sulphate HS: 283322; Isolatek Qwik Gypsu Accelerator; Aluminum Sulfate Accelerator Medium

Aluminum sulfate is an inorganic substance with a molecular weight of 342.15 and is a white crystalline powder.

In the papermaking industry, aluminum sulfate is used as a precipitant for colloidal materials such as rosin glue and wax emulsion, a flocculant in water treatment, a retention aid for foam fire extinguishers, and as a raw material for producing alum and aluminum white. It is also used in the manufacture of petroleum decolorizing and deodorizing agents, medicines, artificial gems, and high-grade ammonium alum.

During sewage treatment, aluminum sulfate reacts with pollutants to form precipitates, playing an important role in water quality control. It is also used as a denitrification and dephosphorization agent to reduce nitrogen and phosphorus content in water. Additionally, in papermaking, it serves as a sizing agent to enhance the water resistance and impermeability of paper.

Aluminum sulfate accelerator medium is an important chemical additive widely used in engineering fields such as construction and road building.

There is indeed a relationship between Isolatek Qwik Gypsu Accelerator and aluminum sulfate.

• Accelerating the setting of gypsum:

Aluminum sulfate can accelerate the setting of gypsum. This is because when aluminum sulfate combines with water, it will form flocs, which resemble bones and veins, adsorbing gypsum particles together, thereby accelerating the setting process of gypsum.

• Application in gypsum-based materials:

Gypsum Accelerator is an accelerator specially designed for CAFCO and ISOLATEK gypsum-based spray plaster materials. It improves construction efficiency by reducing the setting time of SFRMs (Spray-Applied Fire Resistive Materials, spray plaster materials), increasing material yield, and allowing multiple constructions in one day.

• Composition and function:

Gypsum Accelerator is delivered by chemical metering pumps and mixed with SFRM slurry. Although aluminum sulfate is not explicitly mentioned in the specific ingredients, aluminum sulfate is a common gypsum accelerator, and its mechanism of action is similar to that of gypsum accelerator, both of which improve construction efficiency by accelerating the solidification of gypsum.

Low-iron aluminum sulfate is mainly used in mid-range papermaking, sewage treatment, etc.
Other applications:

1. Used as paper sizing agent in papermaking industry to enhance the water resistance and anti-seepage performance of paper;

2. After dissolving in water, it can make small particles and natural rubber particles in water condense into large floccules and remove them from water, so it is used as a coagulant for water supply and wastewater;

3. Used as a purifier for turbid water, as well as a precipitant, fixative, filler, etc.; used as an anti-sweat cosmetic ingredient (astringent) in cosmetics;

4. In the fire protection industry, a foam fire extinguishing agent is composed of baking soda and a foaming agent;

5. Analytical reagents, mordants, tanning agents, petroleum decolorants, wood preservatives;

6. Stabilizer for protein pasteurization (including liquid or frozen whole eggs, proteins or egg yolks);

7. Can be used as a raw material for the manufacture of artificial gemstones, high-grade ammonium alum and other aluminates;

8. Used as a precipitant for the production of chrome yellow and lake dyes in the fuel industry, and can also be used as a fixative and filler.

9. Used as an effective cross-linking agent for animal glue to increase its viscosity. It is also used as a curing agent for urea-formaldehyde adhesives, and its 20% aqueous solution cures quickly.
