Do calcium carbonate and grinding mills for papermaking have broad market prospects?

With the development of neutral papermaking and coating processing technology, calcium carbonate has been widely used as filler and pigment in North America and Europe. Adding Caco3 significantly improves the durability of the paper. Powder mills are widely used in the field of calcium carbonate papermaking, helping to expand the application fields of calcium carbonate.

Calcium carbonate has been used in the papermaking industry for more than 100 years. The use of calcium carbonate products in the papermaking industry is mainly based on two points:

1. Calcium carbonate can change the properties of paper products (which cannot be achieved with wood pulp fibers). Calcium carbonate itself has very important optical properties (such as brightness, opacity, gloss) and printing properties, such as ink absorption. performance, glossiness of the printed formulation, low opacity of the printed formulation to the back, etc. In fact, calcium carbonate is used here as a “functional” pigment;

2. The use of calcium carbonate can greatly reduce the cost of papermaking. With the improvement of technical level, acidic sizing technology in the papermaking industry has gradually been replaced by neutral sizing technology. The application of secondary coating technology has created conditions for the application of calcium carbonate in the papermaking industry. In the manufacturing technology of high-end thermal paper, art coated paper, etc., calcium carbonate is widely used to improve the whiteness, opacity, gloss, ink absorption and other indicators. As my country’s per capita paper consumption increases, the amount of calcium carbonate used in various papermaking applications increases year by year, and the market prospects are very broad.

In papermaking, calcium carbonate is mainly used as filler. Its physical properties are higher than kaolin and heavy calcium GCC, which have the advantages of high transparency, high brightness, high expansion capacity, uniform particle size, and strong pigment. According to the opinions on structural adjustment and technological progress of the papermaking industry proposed by the state, it is necessary to focus on the adjustment and development of high-end newsprint, high-end cigarette paper, high-end printing and writing paper, kraft board paper, high-strength corrugated base paper and other varieties, all of which are inseparable from the use of high-quality corrugated base paper. Quality lightweight calcium carbonate.
