Aluminum Sulfate for Paper Making Industry

Aluminum Sulfate (chemical formula Al2(SO4)3, formula 342.15) is an odorless, lustrous white rhombohedral crystal system crystalline powder with a density of 1.69g/mL (25℃). It is used as a precipitant for rosin gum, wax emulsion and other gums in papermaking industry.

In the paper industry, the application of aluminum sulfate is very wide, can be used as a paper auxiliary, but also can be used as a sewage treatment chemicals. Especially in the production of high-quality white paper, the role of aluminum sulfate is irreplaceable. So, what is the role of aluminum sulfate in the paper industry?
In the paper industry, Aluminum Sulfate can be used as an additive in the papermaking process, play a whitening, sizing, retention, filtration and other roles.

Aluminum Sulfate as a papermaking additive, many users only know that papermaking needs to add aluminum sulfate, but do not know what the role of Aluminum Sulfate in papermaking. Most of the raw materials for papermaking are plant fibers, the production of paper products when adding aluminum sulfate, can play a role in whitening, pulp easy filtration, the use of aluminum sulfate finished paper can also play the purpose of water seepage.
Paper industry if the production of white paper, you can use non-ferrous aluminum sulfate, will not introduce colored impurities.
