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...

Invely-3180 defoamer for paper pulp（black liquor） It is well known that pulping is the process of separating fiber materials from plants to obtain pulp. In the pulping process, a large amount of foam will be produced, affecting the production efficiency and the quality of the pulp board. The role of defoamers in the pulp industry is very critical. It is used to prevent various problems caused by foam during the pulp washing process, such as slurry overflow tank, reducing the efficiency of the pump, the formation of deposits on the paper, pulp water filtration Problems, etc. Invely defoamer 3180 uses innovative silicone chemistry to achieve superior foam suppression. It can be used in black liquor without depositing on paper, improving water filtration performance and effectively helping pul p mills Improve efficiency. Invely-3180 improves production efficiency while reducing total operating costs. Invely-3180 is specially designed for pulp and is also recommended for industrial cleanin...

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...

Foam is always a thorny issue in the pulp&paper industry. Foaming reasons   Once liquid which contain a surfactant or this kind of liquid having a large viscosity is agitated, a large amount of foam which is not easily disappeared is often produced. The reasons why these bubbles are more stable and not easy to disappear are as follows: n   Film elasticity The ability of the liquid film to resist local thinning during the general thinning process is film elasticity. When the liquid film has a thin point, this point is a possible breakage. However, when this is further stretched, the surfactant molecules in this part will be more reduced, and the increase in surface tension will result in a force imbalance, and the surrounding surface will be moved toward a thin point to balance the surface. tension. The movement of the surface layer pulls the liquid of the lower layer together, thus preventing further thinning of the initial weakness and, in turn, foam ruptu...

The overall concentration of China's paper industry is relatively low, and the individual paper market is relatively mature. China's paper industry was affected by the tightening of the second phase of the environmental protection policy. From 2010 to 2015, the paper industry eliminated a total of nearly 40 million tons of backward production capacity. The effect of the industry's de-capacity was initially revealed, and the growth rate of paper and board production and sales was released. Slowly, industry supply and demand entered a period of weak balance. Regional concentration is not much different from previous years According to the survey data of the China Paper Association, in 1118 provinces (autonomous regions and municipalities) in the eastern part of China, the paper and paperboard production accounted for 74.2% of the national paper and paperboard production; the central provinces accounted for 16.3% of the eight provinces (regions); The proportion of 12...
