The paper industry is complex and delicate, and each process is related to product quality, while the foam problem is always a difficult problem to be solved. To address this challenge, the paper market has introduced various types of defoamers to meet the needs of different production processes. In the pulping process, the commonly used defoamers include hydrocarbon defoamers and silicone lotion defoamers. Hydrocarbon defoamers have the characteristics of rapid defoaming and long-lasting foam suppression, especially suitable for the pulp washing stage. The silicone lotion defoamer has better dispersibility and high temperature resistance, and is suitable for high-temperature cooking and other processes. In the paper making process, paper defoamer is mainly used to eliminate foam in white water and fine bubbles entrained between fibers. This type of defoamer usually has the characteristics of fast defoaming speed, long defoaming time, and good dispersibility. In addition, in order to meet environmental protection requirements, modern paper defoamers usually use biodegradable raw materials to ensure that they are harmless to the environment and human health.

Different types of defoamers have different characteristics and applicable scenarios. Therefore, when selecting defoamer, it is necessary to select suitable defoamer type according to the specific production process and foam situation. At the same time, it is necessary to consider factors such as the environmental friendliness, durability, and cost of use of defoamers to ensure a dual improvement in production efficiency and product quality. With the advancement of technology and the increasing demand for environmental protection, the performance of defoamers in the paper market is constantly being optimized and upgraded. In the future, more environmentally friendly, efficient, and intelligent defoamers will become the new favorite of the paper industry, injecting new vitality into the sustainable development of the paper industry.

In the paper industry, choosing the appropriate defoamer is crucial for improving product quality and production efficiency. With the continuous advancement of papermaking technology and the increasing demand for environmental protection, the selection of defoamers in the papermaking market has become increasingly complex. Firstly, when selecting defoamers, factors such as their defoaming ability, durability, and environmental friendliness need to be considered. Defoaming ability is an important index to measure the performance of defoamer, and suitable defoamer should be selected according to the specific production process and foam situation. Durability determines whether defoamers can continue to function during the production process. Environmental friendliness is the basic requirement for defoamers in the modern paper industry, and it is necessary to choose defoamers that do not contain harmful substances and are biodegradable.

Secondly, when using defoamers, it is important to pay attention to appropriate usage and even dispersion. Excessive defoamers may affect the quality and production efficiency of paper, so it is necessary to strictly follow the production requirements and use an appropriate amount of defoamers. Meanwhile, defoamers need to be evenly dispersed in the slurry or coating liquid to ensure their full effectiveness.

Finally, regular testing of the effectiveness of defoamers is also very important. Through regular testing, it is possible to timely understand the usage of defoamers, adjust the amount and method of use to adapt to changes in production. In addition, more suitable types of defoamers can be selected based on the test results to further improve production efficiency and product quality.

In summary, choosing the appropriate defoamer and mastering the correct usage techniques are crucial for paper companies. Through scientific and reasonable selection and use of defoamers, the foam problem can be effectively solved, product quality and production efficiency can be improved, and a strong guarantee for the sustainable development of paper enterprises can be provided.
