The global papermaking chemicals market will exceed 42 billion US dollars in 2025 Relevant data show that the global papermaking chemicals market will exceed 42 billion US dollars in 2025. Papermaking chemicals as follow: process chemicals, functional chemicals, pulping chemicals on the other hand by type, they can be divided into special chemicals, commodity chemicals, etc. Papermaking chemicals are specifically used to change paper properties, including color, strength, recycling performance, basis weight, quality, and related attributes. In order to obtain specific functions, the paper undergoes various processes such as bleaching, beating, strengthening and sizing. In order to further improve paper quality and improve multiple functions, people in the industry continue to improve the performance of paper, and it is expected that the scale of the chemical industry will be further promoted in the next few years. Why does paper chemicals has been increasing? As the pursuit of paper fi...

How should we select defoamers / antifoams for paper pulp? Pulp and paper antifoaming agents is very necessary in papermaking, because a lot of foam will be generated in the process of papermaking and pulping, the surface tension of the generated saponification is less than the surface tension of black liquor produced by cooking materials, making it It exists in the surface layer of black liquor and forms a thin film, which forms foam under the mixing action of air. The papermaking process is mainly divided into two major steps,  Washing pulp Papermaking No matter which step inevitably produces foam, so you need to use defoamers/antifoam for paper industry, there are many types of defoamers, the following is for everyone Introduce the characteristics of papermaking defoamers. Excessive foaming will result in the loss of fibers and raw materials. Further, the presence of air in the wet paper web can affect the filtration rate of paper in the paper making pulp defoamers is a better s...

As we all know, compared with the developed paper-making countries in Europe and America, due to the shortage of land resources in China, especially the shortage of forest resources, we must protect limited forest resources. Therefore, the urgent issue that chinese paper industry must be face is : how to use artificial fast-growing forests to produce short fibers and recycled fiber/waste paper, by the way, using fine chemicals can help paper workers effectively alleviate and solve this problem. So here let us learn what exactly is fine chemicals? Fine chemicals mainly refer to chemicals used in the wet-end flow system of paper machines. Everyone knows that the wet end of the paper machine is a study of the various materials in the paper stock (slurry circuit and slurry circuit) in the process of water filtration, retention, forming and white water circulation, water, fiber and other additives. The science of interaction and action law; it is also a science to study the interaction...

Invely-620D in papermaking pulping black liquor trial application: Costomer introduction: A paper mill in Shandong Province has an annual output of 600,000 tons. The raw material is hardwood. The foaming in the black liquor of papermaking is serious. Lead into efficiency of vacuum washing is greatly reduced, which seriously affects the stability of production and the quality of paper products, and even causes the machine to stop. . After Learned our defoamer, sent 20 kg of black liquor to our company for testing and selection, recommended the Invely-620D, the foam was effectively controlled. Date sheet Product Name: Defoamer Invely-620D Key property: ·    Good compatibility, silicone grease does not precipitate and float after moderate dispersion in the system; ·    Easy to disperse in water, good compatibility within the addition; ·    Acid and alkali resistant Appeara...
