Overview of Surface Sizing agent

The surface sizing agent  paper or cardboard in the process of a process, usually located in the end of the paper machine drying, the sheet
Not completely dry but has a certain strength to spray a layer of glue layer film formed by the subsequent drying in paper and paperboard surface, so as to achieve the purpose of change of paper or paperboard surface properties. From the development of paper industry, paper surface sizing is one of the essential process of surface sizing agent can be added to improve the performance of the sheet or increase in the surface of paper or paperboard, water resistance additives. Originally, due to the technical level and the limitations of the paper request, surface sizing can only be used on special paper, such as: the banknote paper, bond paper, sea drawings and other. With the technological level of the paper industry, the paper surface sizing agent has become a conventional paper-handling processes, especially in recent years due to printing, photocopying, fax, universal cultural paper, wrapping paper and corrugated surface, strength and The water resistance of a higher demand, the paper industry in the constant quest for new surface sizing  agent techniques.

The use of PAM powder (anion)

PAM powder (anion) used in textile, printing and dyeing industry. PAM powder (anion)as a fabric of sizing agents, finishing agents, and can generate supple, wrinkle-free, anti-fungal protection layer. With its strong moisture absorption characteristics, to reduce the off rate in spinning yarn. PAM powder (anion) amide for the treatment agent to prevent static and flame retardant fabrics. PAM powder (anion)is used as auxiliaries, PAM powder (anion)can make the product adhesion, bright and high, but also as the bleaching of non-silicone polymer stabilizers.

Benzyl chloroformate first aid measures

Skin contact with Benzyl chloroformate, immediately remove contaminated clothing, rinse with plenty of water for at least 15 minutes. For medical treatment. Eye contact with Benzyl chloroformate, immediately filed eyelid, with plenty of water or saline thoroughly washed at least 15 minutes. For medical treatment. Inhalation of Benzyl chloroformate rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. For medical treatment. Ingestion Benzyl chloroformate water were found to blues or egg white. For medical treatment.
