Non ferric Aluminum Sulfate for Paper Making good shows core features as follow:
Making High purity
The iron content is strictly controlled at an extremely low level (much lower than that of ordinary industrial aluminum sulfate), avoiding the influence of iron ions on the whiteness and color of the paper.
01
Acidic
The aqueous solution is weakly acidic (with a pH of approximately 3-4), which can regulate the pH of the pulp and meet the requirements of the papermaking process for the pH environment.
02
Stability
It is not prone to decomposition at room temperature, has good compatibility with pulp fibers, fillers, and other components, and has no harmful side reactions.
03
Solubility
It is easily soluble in water, forms a uniform aluminum ion solution after dissolution, and is convenient for uniform dispersion in the pulp.

Non Ferric Aluminum Sulfate for Paper Making Applicable Scenarios
High whiteness paper
Such as writing paper, copy paper, dictionary paper, etc., ensuring the paper remains white and free from stains for a long time.
Fine processing paper
Such as cigarette paper, food packaging paper (must comply with food safety standards to avoid iron ion migration and contamination).
Colored paper
Such as colored card paper, decorative paper, etc., ensuring uniform color and high durability.
High-end cultural paper
Such as coated paper, offset paper, etc., with strict requirements for sizing effect, strength and whiteness.
Usage Notes
During storage of non ferric Aluminum Sulfate for Paper Making, it should be kept dry and avoid direct contact with iron containers (to prevent the introduction of iron ions from secondary contamination).
When Non ferric Aluminum Sulfate for Paper Making dissolving, the water temperature should not be too high (≤ 60℃) to avoid affecting the activity of aluminum ions.
Depending on the type of pulp (wood pulp, straw pulp, etc.), the type of sizing agent, and the quality requirements of the paper, the optimal addition amount (usually 0.5% - 2% of the dry pulp weight) should be determined through a small-scale test.
Aluminum sulfate mainly used in paper making,besides it also used in industrial sewage and drinking water treatment agent,oil industry used as clarifying agent, petroleum industry used as deodorant decolorizing agent, cement coagulant, textile industry, fire protection field, catalyst carrier, and other chemical raw materials to prepare aluminum salt and titanium dioxide, soil amendment, pigment manufacturing, etc.
