Superiority:
Because of the amino and carboxyl groups in chitosan, it can be dissolved in dilute acid to form a high viscosity colloid solution. The water solution is a cationic electrolyte, which has good film forming property, and can be used in the paper.
Chitosan molecular weight material for the linear and molecular weight from tens of thousands to millions of unequal, the fiber has sufficient adhesion strength and fiber schematic bridge ability. So the paper better enhancement and retention effect.
Shell similar to that of chitosan with a molecular weight of cellulose, cellulose and its chemical structure similar and straight chain type, in aqueous solution showed positive also has certain cations and good film-forming property, good permeability and stable water resistance of. The above characteristics of chitosan are well suited for use as a surface sizing agent for paper.
Chitosan itself is a kind of preservative, used as a paper surface sizing agent, has good mothproof, mildewproof effect, therefore for the production of books and printing paper, is especially popular.
Chitosan can also with gelatin, polyol a polyacid compound, to form the composite sizing agent, made of special paper for offset printing, the printing plate which can be used for sucking and the absorption of the ink. Capacitor paper in front of the pressure, with 2% 0.3% chitosan acetic acid solution surface treatment, can significantly improve the electrical resistivity of paper.
At present, the application of chitosan in the paper industry is the most widely used in the paper. As an increasing agent for paper, it is generally believed that the ideal of the increase of dry - enhancing agent should have the following conditions: 1. The relative molecular mass, with film-forming ability, have sufficient adhesion strength and fiber to fiber in frame bridge. There are many positive charge centers and the carboxyl groups in the molecular chain, which is convenient for the formation of electrostatic and hydrogen bonding. Because chitosan is completely in line with the above conditions, so it has a very good effect of increasing the dry.
Our company produces special chitosan, which is rich in active groups of molecules can be formed with the cellulose and hydrogen bonds are closely combined, with a significantly enhanced, retention and auxiliary effect, the effect of non wood fiber pulp is better.
This product can improve the retention rate of slurry and filling, reduce the processing strength of white water and increase the wet strength of paper and dry strength, reduce the proportion of wood pulp. A variety of properties, such as increasing the breaking strength of the paper, relative fracture tolerance, folding endurance, humidity and water resistance, etc..
