In the paper industry, defoamers play a crucial role as a key auxiliary material. With the continuous advancement of papermaking technology and the sustained growth of market demand, the application of defoamers has become increasingly widespread, which is of great significance for improving the quality of papermaking products, increasing production efficiency, and reducing production costs.
In the process of papermaking, the pulp contains a large number of surfactants and other additives, which are easy to form stable foam in the processes of mixing, cooking, etc. These foam will not only affect the forming and quality of paper, but also reduce production efficiency and increase energy consumption. Therefore, the application of defoamers is particularly important.
Defoamer can destroy the stability of foam and make foam burst quickly by reducing the surface tension of liquid. In the papermaking process, defoamers are widely used in various applications, including pulp making, paper coating, and paper drying. In the pulping process, defoamers can effectively control the foam generated by natural surfactants, and improve the pulping efficiency. In the process of paper coating, the use of defoamers can ensure the uniformity and stability of the coating liquid, improve the quality and appearance of the paper. In the paper drying process, defoamer can prevent foam from interfering with the paper and ensure the drying effect of the paper.
Choosing the appropriate defoamer is crucial for improving papermaking efficiency and quality. The modern paper industry has increasingly high requirements for environmental protection, so defoamers need to meet environmental standards, be free of harmful substances, and be safe and harmless to the environment and human health. In addition, the defoaming ability, durability, and dispersibility of defoamers are also important factors to consider when selecting.
In the papermaking market, with the increasing environmental requirements and continuous progress in papermaking technology, research and development of defoamers will also continue to deepen. In the future, defoamers will be more environmentally friendly and efficient, providing strong support for the sustainable development of the paper industry.
