Usage & Packing
Usage:
1) It's used for purification of drinking water and wastewater treatment by settling of impurities by
means of precipitation and flocculation.
2) 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.
3)It is used for color fixing in Naphthol based dyes for cotton fabric.
4)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.
5)Dyeing and printing on cloth. When dissolved in a large amount of water that has a neutral or slightly alkaline pH, the compound produces a gooey substance, aluminum hydroxide. The gooey substance helps dyes stick to the cloth fibers by making the dye water insoluble. The role of aluminum sulfate, then, is as a dye “fixer,” which means that it combines with the molecular structure of the dye and the fabric so the dye doesn’t run out when the fabric gets wet.
