Paper sizing agent is a papermaking additive, also known as pulp sizing 0010010 nbsp;,Point pairpulp, Paper, paperboard for processing to obtain the performance of fluid penetration resistance addedOne kindChemicals. Such chemicals have hydrophilic groups andHydrophobic group, Orienting the outer side as a hydrophobic group on the surface of the fiber makes the paper endowHydrophobicAnd resistance to fluid penetration. exceptBlotting paper,filter paper,stencil,Cigarette paper, Tissue paper and other paper types, almost all papers are requiredSizing.It can be seen that the effect of the sizing agent is very large.

Paper sizing agent is mainly divided into pulp sizing and surface sizing. 0010010 nbsp;Sizing on paperwhenCan improve the paper's resistance to water, oil, andPrinting inkAnd other properties, while improving smoothness,Hydrophobic3. Printing adaptability.

tableSurface sizing is a process in the processing of paper or cardboard. It is usually located at the end of the drying section of the paper machine, so that the paper sheet is sprayed with a layer of glue when the paper is not completely dried but has a certain strength. A glue film is formed on the surface of the cardboard to achieve the purpose of changing the surface properties of the paper or cardboard.

From the point of view of the development of the paper industry, surface sizing of papermaking is one of the indispensable processes. Surface sizing can improve the performance of paper sheets or increase the surface resistance of paper or paperboard.

Originally, due to the limitations of technical level and paper type requirements, surface sizing agents can only be used on special paper types, such as: banknote paper, bond paper, sea drawings, etc. With the improvement of the technical level of the paper industry, the surface sizing of paper has become a conventional paper processing process, especially in recent years due to the popularization of printing, copying and faxing, the surface properties, strength and Water resistance puts forward higher requirements, so the paper industry is constantly seeking new surface sizing technology.

This shows that our paper sizing agent will usher in a larger market, face more development opportunities, and the development prospects are also very impressive.
