6 factors affecting the surface sizing of Paper Plate Making Machine

The influence of paper substrate

The paper page is large in quantity, and the picking quantity of the adhesive is relatively large. The greater the tightness, the smaller the picking amount of the adhesive. In addition, Paper Plate Making Machine the paper page capillary structure and fiber pore size affect the paper page on the picking amount of rubber.

Although the plastic material on the surface of rough paper finishing role, but the surface roughness is not ideal paper page, even if the increase in the picking amount of rubber material is difficult to achieve the ideal finishing effect. Therefore, the uniformity of the paper page is the first condition of surface sizing.

Influence of the sizing degree of the paper page

The size of the sizing of paper pages is an important factor affecting the picking amount of the sizing press. Completely not sizing paper more than the adhesive paper to absorb 100% of the plastic material, Paper Plate Making Machine while the paper absorption of water is also more, resulting in decreased strength, the rate of breakage increased. Once the sizing degree of the paper page reaches a certain value, the effect of paper sizing is not obvious.

The effect of moisture on paper page

To enter the sizing paper page moisture content, not only affect the size of the paper page on the pickup, and the uniformity of the vertical and horizontal water directly affect the homogeneity of the absorption of plastic materials. Paper Plate Making Machine Therefore, the paper moisture entering the sizing press is the key parameter to be controlled in the process of production. In the production process, its water general control in the $number appropriate, at this time to obtain the maximum pickup capacity.

The influence of speed of Paper Plate Making Machine

For ordinary sizing press, with the increase in Paper Plate Making Machine speed is conducive to paper page on the picking, when the speed of Paper Plate Making Machine from 100m/min to 300m/min, Paper Plate Making Machine the paper page to starch pickup increased rapidly. But the speed increased to 650m/min after the paper page on the starch pickup no significant increase. For the measurement of sizing, in the case of plastic material supply unchanged, with the increase in the speed of the paper page in the pressure zone of time to reduce, the paper adsorption of adhesive material is relatively reduced.

Effect of Sizing Press

Horizontal sizing is higher than vertical sizing. The lower pressure is advantageous to increase the thickness of the liquid film through the pressure zone. Larger diameter and lower hardness of the sizing roller, is conducive to the absorption of paper sheet time.

The influence of sizing compound

In a certain range to improve the solid content of the binder can improve the paper page on the picking amount of rubber, but also to reduce the drying load. Paper Plate Making Machine But increasing the solid content will make the Rheological property of the rubber material decline. The viscosity of the plastic material affects the rheological properties and membrane transfer of the adhesive, and the low viscosity is advantageous to increase the in, and the viscosity is good for increasing the thickness of the liquid film through the pressure zone.

Cationic starch adhesive and oxidized starch, such as anion or non-ionic modified starch adhesive, because of its chemical affinity to the paper fiber increased, Paper Plate Making Machine the use of starch gel liquid permeability slowed down, starch more left on the surface of the paper.
