Paper is an important part of our national economic development, the production of paper occupies a quarter of the world. The emergence of paper brought convenience to our lives, but also created a glorious history of many factories. At any time the standard of living has improved, and people's requirements for the quality of material paper have become increasingly stringent. What affects the quality of paper is the foam factor, paper defoamer is the key to solving the foam. See how paper defoamer manufacturers solve the problem of pulp foam.

In the entire paper industry, the amount of defoamer is not large, but its role can not be ignored. From the preparation, cooking, washing, bleaching, pulp supply, sizing, and coating to the recycling of waste liquor, etc., each link will produce foam, interfering with normal production, so that the quality of paper declines, and in serious cases will make normal production can not continue. Foam elimination has chemical method, physical and mechanical methods. Currently the most widely used is the chemical defoaming method, that is, the use of defoamers to "inhibit" the formation of foam or "break" the foam that has been generated. As an experienced manufacturer of paper defoamer, I would like to share with you a real-life case of paper foaming.
Mr. Huang of Jiangsu paper mill in 2022, his factory's annual output of 60 tons, raw materials for broadleaf wood, in the paper pulp stage foaming is very serious, foam not only impedes the production schedule, while the production of finished paper quality is not good, received a large number of complaints from customers and agents. Nanhui paper defoamer manufacturer for the paper industry foaming situation, the development of a set of cost-effective defoaming programs.

Paper defoamer manufacturers for the pulp foam development of defoamer types of modified silicone polyether (compound type), fatty alcohols, high carbon alcohols, polyethers, silicones, etc., can meet the needs of the papermaking process in each foaming link, so what are the benefits of using defoamer for the paper industry?
1.The pulp black liquor system in the foam was effectively controlled, the thickness of the pulp in the pulp washer increased, and the sizing rate effectively improved.
2.The pulp washing degree is improved, and the filtering water to improve.
3.The concentration of the black liquor is reduced, which helps the recovery of residual alkali.
4.Stable index of paper formation and improved paper quality.
