The Function of Surface Sizing
The surface sizing of cultural paper is mainly to obtain better printing and writing performance, improve surface strength, and reduce the problem of losing hair and powder. The surface sizing of corrugated paper is to obtain higher ring strength and better water resistance and moisture resistance. The value of ring pressure strength after surface sizing will be greatly improved. After adding water and moisture resistance sizing agent in the glue solution, the moisture resistance and the moisture resistance of the corrugated paper can be greatly improved, and the cost of using the sizing agent in the slurry is often doubled or even several times.
The Basic Configuration Of Surface Sizing Machine
The liquid itself has a certain corrosive effect on the equipment, so the roller, frame and walking table of the sizing machine are usually made of stainless steel or processed with stainless steel. The upper and lower rollers of the sizing agent are a hard roller and a soft roller, and the hard roll is often plated with hard chromium on the prior culture paper machine.
Operation Of Surface Sizing Machine
Prior to the operation of sizing machine, the top roller is running and then draws the paper, this way is suitable for low speed paper machine, but often encounter the paper roll sticking wrap problem in low speed paper machine operator can rely on skilled or manually lighted paper, which is in high speed paper machine trouble. High speed paper machine using the first and then cited paper and then glue the way, now the transmission control precision can meet the operation requirements of sizing machine, it should be noted that after sizing the tension control, if not equipped with automatic tension detection control system, you need to adjust the speed difference to control sheet tension, usually after sizing after drying speed difference to rise 0.6-1.6m/min to maintain the tension of the sheet.
