Iron Oxide Pigment Used in Papermaking and Pigment Dispersion

Iron oxide pigments are widely used and important in papermaking and color paste, mainly in the following aspects:

I. The application in papermaking

1. Coloring effect:

Iron oxide pigments have strong color stability and coverage, which can give paper a vivid and long-lasting color. In the process of papermaking, by adding an appropriate amount of iron oxide pigment, the paper can be made to present a rich color effect, which can increase the aesthetics and decoration of the paper. This coloring effect not only enhances the visual effect of the paper, but also satisfies the demand for colored paper in different fields.

2. Improved Paper Performance:

Iron oxide pigments can also be used as fillers or additives to tightly bind to paper fibers to improve the whiteness, opacity and physical strength of the paper. At the same time, it can also improve the printing performance and gloss of the paper, making the print clearer and brighter.

3. Functional Applications:

In the paper industry, iron oxide pigments are also used to prepare paper with specific functions. For example, by adding iron oxide pigments, paper with waterproof, wear-resistant, anti-aging and other properties can be prepared to meet the needs of special purposes.

II. The application in the Dispersion

1. Preparation of pigment dispersion:

Iron oxide pigment is one of the important raw materials for the preparation of pigment slurry. Through mixing, dispersion and other processes, iron oxide pigments are compounded with other pigments, resins, additives and other raw materials to prepare pigment slurries with good performance. This pigment paste is widely used in paper, plastics, coatings and other fields, providing strong support for the coloring and decoration of products.

2. Improve colorant performance:

Iron oxide pigments have good dispersion and stability in the color paste, which can ensure that the color paste maintains uniform color and performance during storage and use. At the same time, it can also improve the hiding power and color vividness of the color paste, making the coated product more beautiful and durable.

3. Adapt to a variety of application needs:

Due to the variety of color options and excellent physical and chemical properties, iron oxide pigments can be formulated and modified according to different application needs. For example, when preparing a specific color of paper or paint, the desired color effect can be achieved by adjusting the type and amount of iron oxide pigment.

In summary, the application of iron oxide pigments in papermaking and colorant paste has a wide range of prospects and important value. With the development of technology and the growth of demand, the application of iron oxide pigments in these fields will be more in-depth and extensive.
