It is believed that everyone is familiar with papermaking. Papermaking is a major invention of ancient people. Now with the development of science and technology, the development of paper industry is changing with each passing day. Paper has become an important item in our daily life. Our life cannot be separated from paper, but you do you know? The headache in the papermaking industry is that the foam produced when making paper is more serious. When the foam is not well controlled, it will cause splashing of liquid and loss of fiber. Seriously, it will cause injury to people. When the bubble problem comes down, you should find a solution - paper defoamer.
Reasons for paper bubbles in papermaking:
1. Foaming in the pulping process
2, washing, filter, bleaching, dehydration, papermaking, sizing, coating blistering
3. Foam caused by adhesive in the coating formulation
4. Produce a large amount of foam in the papermaking process
5, the slurry falls in a waterfall, the foam caused by the air leakage of the slurry pump
6, the cone slag discharge slag pressure is too low
7, water treatment discharge foaming
Solution for papermaking defoamer:
In the process of papermaking, bubbles are sure to meet due to various factors. Many customers like to use physical methods to solve them, such as ensuring the sealing of each device, installing deaerator, etc. But you know, In fact, these methods are not only costly but also inefficient, because most of the bubble generation is not caused by physical factors, but chemical properties, so it is better to take the initiative to attack before using the chemical method - paper defoamer to solve the foaming!
Pick papermaking defoamer:
The choice of papermaking defoamer requires the following three points: 1. Alkali resistance and high temperature resistance. 2, can not have the phenomenon of stains, oil, etc. 3, lasting to maintain the performance of suppression foam. However, the defoamer developed by the Chinese Federation not only solves these difficulties, but also has good dispersibility, dynamic defoaming, and no antimony. It can save the mechanical defoaming method and save cost. The antifoaming agent is suitable for: papermaking white water; removing the surface foam containing rosin gum and removing the bubbles adsorbed on the fibers in the water. The surface foam containing the modified starch white water system and the bubbles adsorbed on the fibers in the dehydration are removed. The foam in the water containing the polypropylene guanamine retention aid system is removed. The surface foam containing the AKD emulsion white water system and the bubbles adsorbed on the fibers in the dehydration are removed. Starch gelatinization; other processes that cannot use organic germanium.
Central Federal Defoamer (alias: anti-foaming agent) - focus on solving various foam problems in production and processing, because of the focus on professionalism.
The Chinese Federation provides samples free of charge, and the defoamer is manufactured in strict accordance with industry standards. Contact us about foam inhibitors or related needs.
