The applicator is divided into two types, horizontal and inclined. Pneumatic pressurization, surface sizing is usually used 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.


The applicator is divided into two types, horizontal and inclined. Pneumatic pressurization, surface sizing is usually used 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. The emulsified glue is continuously, uniformly and stably applied to the surface of the paper by a surface applicator, and a series of physical effects such as wetting, osmosis and the like are formed to form an extremely thin waterproof layer on the surface of the paper. The amplitude improves the water absorption of the paper, and at the same time, the bonding strength between the fibers and the tightness of the paper are improved under the action of the glue, thereby improving the technical indexes such as the lateral ring pressure index and the longitudinal crack length of the paper.


When the glue applicator is in a diagonal arrangement, a pair of applicator rolls are arranged at an inclination of 30° in the horizontal direction, and the horizontal type is 0°; the paper sheets drawn from the dryer group enter the glue tank composed of the two applicator rolls. The surface is sized and then dried in the next set of dryers. Two rolls: one is a chrome roll or an artificial stone roll, one is a special rubber for sizing, the upper roll is fixed, the rubber roll side is pressurized upward, the pressurized form is pneumatic, and a double curved pneumatic device is used. The transmission is divided into: single-point transmission and two-way transmission.
