The Impact Of Iron Free Aluminum Sulfate On The Papermaking Industry

In the papermaking industry, the use of iron free aluminum sulfate can usually be divided into many types, and it can mainly be used as a papermaking additive, retention and filtration aid, paper reinforcement agent, water treatment agent, etc. And when we use it, aluminum sulfate without iron does not contain iron, so it will not have a negative impact on the whiteness of the paper when used in white paper production.
1. Paper pulp retention and filtration aid: Iron free aluminum sulfate has an excellent retention and filtration effect on paper pulp.
2. Paper enhancer: After using this product, it will not have any adverse effects on the color of white paper, and it has also significantly improved the various properties of white paper. Therefore, it is very suitable for use in excellent paper production.
3. The addition of iron free aluminum sulfate to papermaking pulp often reduces its impact on the pH value of the pulp.
4. This product is suitable for a wider pH range during the papermaking sizing process. Moreover, iron free aluminum sulfate is a sizing agent suitable for acidic and neutral environments, with lower corrosiveness to papermaking systems and easier treatment of wastewater generated; Iron containing aluminum sulfate is only suitable for sizing in acidic environments, and iron containing aluminum sulfate often has a certain impact on paper quality and equipment.
5. Generally speaking, iron free aluminum sulfate can increase the toughness of paper.
The above is the complete introduction about the use of iron free aluminum sulfate in the papermaking industry. It is mainly used as a sizing agent for papermaking, as well as a flocculant for drinking water, industrial water, and wastewater treatment. It is also a raw material for producing artificial gemstones and other aluminum salts such as ammonium alum, potassium alum, and refined aluminum sulfate. In addition, aluminum sulfate is also widely used in the production of excellent clarifying agents, petroleum deodorizing and decolorizing agents, concrete waterproofing agents, paper forging whitening, titanium dioxide post film treatment, and catalyst carriers.
