Application and role of talcum powder in paper
1. Improve paper gloss
The most widely used talc powder in paper is used as a filler, which can effectively improve the gloss and whiteness of paper. Talc powder has good optical properties and can reflect and scatter light, resulting in strong whiteness and gloss.
2. Improve the mechanical strength of paper
The application of talc powder in paper can also improve the mechanical strength and durability of paper. It has high hardness and compressive strength, which can effectively enhance the mechanical properties of paper such as tensile strength, wear resistance and tear strength.
3. Improve the printing performance of paper
In the printing process, talc powder is widely used in coated paper, printing paper, wrapping paper and other fields. Talc can effectively improve the water absorption of paper, enhance the paper coating, so as to improve the smoothness and printing quality of paper, reduce printing costs.
4. Other applications
Talc also has other applications in paper production, such as fillers in the chemical fiber industry, sustained-release agents in the pharmaceutical field, regulatory agents in the cosmetic field, and so on. At the same time, talc can also be used as an important raw material in the field of waterproof coatings and fireproof materials in building materials.
In short, talc powder has an important application and role in paper production, which can effectively improve the quality, performance and processing performance of paper. In the future, with the continuous development and innovation of science and technology, the application prospects of talc powder in the field of paper will be broader, bringing more convenience and comfort to human life.
