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...

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...
