Usually the production of kraft paper, high-strength corrugated paper, and cultural paper requires the use of a sizing machine.
The purpose of surface sizing is usually to prevent liquid penetration, obtain better surface properties and improve the physical properties of paper sheets (such as surface strength and internal bonding force) , is an effective means to improve the performance of base paper.
The sizing machine currently used is an inclined sizing machine, pneumatic pressure, the purpose of surface sizing is usually to prevent liquid penetration, obtain better surface properties and improve the physical properties of paper sheets (such as surface strength and internal bonding force) , is an effective means to improve the performance of base paper.
The sizing machine is arranged in an oblique row, with a pair of sizing rollers arranged in a horizontal direction inclined at 30°; the paper sheet drawn by the drying cylinder group enters the sizing tank composed of two sizing rollers for surface sizing, and then enters the lower sizing roller. Group dryer drying. The sizing machine has two rollers: one is a chrome-plated roller or an artificial stone roller, and the other is a special rubber for sizing. The upper roller is fixed,and the rubber roller is pressurized sideways. Transmission is divided into: single-point transmission, two-way transmission. Usually the production of kraft paper, high-strength corrugated paper, and cultural paper requires the use of a sizing machine.
