In the paper industry, the problem of foam has been puzzling many paper enterprises. Foam will not only affect production efficiency, but also may cause adverse effects on paper quality. In order to solve this problem, paper companies have chosen to use paper defoamers. Therefore, when selecting defoamer for paper making, its defoaming effect should be considered first. Defoamer should have good defoaming and foam inhibition ability, which can quickly eliminate foam in the paper making process and inhibit the production of foam for a long time. Next is its stability. Defoamers should have good chemical stability and not react with other chemicals in the papermaking process, ensuring the smooth progress of the production process. In addition, its environmental friendliness should also be considered. With the increasing awareness of environmental protection, it is particularly important to choose environmentally friendly defoamers. Non toxic, odorless, and non polluting defoamers should be selected to reduce environmental pollution.

There are various types of commonly used paper defoamers in the market, such as organosilicon defoamers, polyether defoamers, polyester defoamers, etc. Enterprises should choose suitable defoamers based on their own production processes, pulp types, and usage needs.

Defoamers are widely used in papermaking process. In the pulping process, foam is easily produced due to the addition of chemicals and mechanical agitation. Using defoamer can effectively control foam and improve pulping efficiency. In the paper making stage, foam will make the paper appear holes, spots and other defects, reducing the strength and flatness of the paper. The addition of defoamer can effectively inhibit the generation of foam and eliminate the existing foam, so as to ensure that the paper can be evenly formed in the wire section and press section. In the coating and surface treatment process, the application of defoamers can ensure the uniformity of coatings and coatings, and improve the surface quality of paper.

In addition, papermaking defoamers can also be used in papermaking wastewater treatment, antifreeze, distillation systems and other fields, providing comprehensive support for the production of papermaking enterprises. Paper defoamers play an important role in the paper industry. Choosing the appropriate defoamer and applying it correctly can not only improve production efficiency, but also enhance paper quality and reduce production costs. With the continuous advancement of technology and the increasing demand for environmental protection, the performance and environmental performance of defoamers in papermaking will continue to improve in the future, contributing to the sustainable development of the papermaking industry.
