Lead: With the gradual maturity of water-based coatings production technology, water-based coatings are widely used by consumers for their advantages of stable color and environmental protection. As an important additive of water-borne coatings, the manufacture of water-borne color paste has been paid much attention, but the articles in this field are rarely popularized on the Internet. Today, Bian Xiao will take you to unveil its mystery and walk into this mysterious production workshop.

As an indispensable part of waterborne coatings, waterborne color paste is very important in its production process. However, because it is a new technology, its production and research have been kept secret. In order to let consumers know more about water-based color paste, Bian Xiao will reveal the secret for everyone today. Please pay attention.

■ Preparation of water-based color paste

◆ First of all, prepare the raw materials, because they are chemical raw materials, so there are many technical terms, which you may not understand very well, as long as you know roughly which big manufacturers are. Titanium dioxide R-828 is produced by Kemeiji Company of the United States; Langsheng company in Germany produces iron oxide series pigments; Organic pigments account for a large proportion in production, so there are a little more manufacturers, including Swiss Ciba Company, German BASF Company and Japanese DIC Company. ? I will introduce these to you. Generally speaking, there are many foreign companies. The following picture shows the dispersant produced in China.

◆ After introducing the materials, introduce the instruments needed for production. Mainly include: grinding machine, three-roll grinding machine, scraper fineness meter, high-speed dispersion machine, rod coating machine, color difference meter, scanning electron microscope, electronic balance, generally also produced by foreign manufacturers. You just need to know it.

I'll introduce you to a material for making white paste in water-based color paste. The formula is as follows.

■ Everyone should have a general understanding of the production process of water-based color paste. Let's talk about how the color matching of water-based color paste is carried out. After all, this is closely related to us. There are generally two kinds of color paste color matching, one is machine color matching and the other is manual color matching. Let's introduce them to you respectively.

Machine color matching: the so-called machine color matching means that the color paste manufacturer provides the operators with products prepared according to the color card, or will send someone to give on-site guidance.

◆ Artificial color mixing: it is to mix and produce new colors according to the principle of three primary colors that we learned when we were young (remember that the three primary colors are red, yellow and blue).

■ Water-based color paste can be divided into water-based organic color paste and water-based inorganic color paste according to different additives. The main difference between these two color pastes lies in the oil absorption value. The oil absorption value of inorganic color paste is relatively low, so it disperses quickly when used, but there are not as many kinds of pigments as organic color paste, so there are more organic color pastes sold in the market.

After reading this article, do consumers have a very vivid concept of the production process of water-based color paste, and a clear concept choice of color matching and later product selection of water-based color paste, hoping to help everyone.
