Paper machine sizing machine is divided into horizontal and oblique two forms, pneumatic pressurization, surface sizing is usually to prevent liquid penetration, obtain better surface properties and improve the physical properties of the paper (such as surface strength and internal bonding), is an effective means to improve the performance of the base paper. Through the surface sizing machine to the emulsified glue continuous, uniform and stable coating on the surface of the paper, through a series of physical effects such as infiltration, osmotic extrusion, etc., a very thin waterproof layer is formed on the surface of the paper, which greatly improves the water absorption of the paper, and at the same time improves the bonding strength between the fibers and the tightness of the paper under the action of the glue, so as to improve the transverse ring pressure index, longitudinal fracture length and other technical indicators of the paper.
When the sizing machine is arranged in an oblique column, a pair of sizing rollers are arranged at an inclination of 30° in the horizontal direction, and the horizontal formula is 0°;The paper pages attracted by the dryer group enter the sizing tank composed of two sizing rollers for surface sizing, and then enter the next group of drying cylinders. Two rollers: one is a chrome-plated roller or artificial stone roller, the other is a special rubber for sizing, the upper roller is fixed, the rubber roller side is pressurized upward, the pressurized form is pneumatic, and the double-curved air tire device is adopted. The transmission is divided into: single point transmission and bidirectional transmission.
