Embodiment 1

[0018] A mixture of melamine resin glue and 220-mesh corundum powder with a solid content of 60% and a viscosity of 20s (tested in 4 cups at 20°C) is used. The weight ratio of melamine resin glue and 220-mesh corundum powder is 4:1. Stir evenly in the main storage tank 2 with the agitator 1, open the manual valve 3, the mixture flows through the discharge material pipeline and enters the filter device 7 under the delivery of the peristaltic pump 6, of which the peristaltic pump 6 is Ponndorf P-classic 50twin, the filter device The size of the screen mesh is 1mm / 18 mesh; the filtered mixed material is transported to the nozzle 8, and the impregnated surface paper (base paper unit weight 22g / ㎡) is sandblasted on one side, and the excess mixed material is refluxed In the auxiliary glue storage 10, the liquid level controller 9 is used to control the liquid level of the mixed material in the auxiliary glue storage 10, wherein the liquid level controller 9 can choose a tuning fork l...

Embodiment 2

[0020] A mixture of melamine resin glue and 180-mesh corundum powder with a solid content of 55% and a viscosity of 19s (tested in 4 cups at 20°C), the weight ratio of melamine resin glue and 220-mesh corundum powder is 3:1, and the mixture is set Stir evenly in the main storage tank 2 with the agitator 1, open the manual valve 3, the mixture flows through the discharge material pipeline and enters the filter device 7 under the delivery of the peristaltic pump 6, of which the peristaltic pump 6 is Ponndorf P-classic 50twin, the filter device The size of the screen mesh is 1mm / 18 mesh; the filtered mixed material is sent to the nozzle 8, and the surface paper (base paper unit weight 22g / ㎡) is sandblasted on one side, and the excess mixed material is returned to In the auxiliary glue storage 10, the liquid level controller 9 is used to control the liquid level of the mixed material in the auxiliary glue storage 10, wherein the liquid level controller 9 can choose a tuning fork li...

Embodiment 3

[0022] A mixture of urea-formaldehyde resin glue and 240-mesh corundum powder with a solid content of 48% and a viscosity of 17s (tested in 4 cups at 20°C), the ratio of melamine resin glue and 220-mesh corundum powder is 4:1, and the mixture is set Stir evenly in the main storage tank 2 with the agitator 1, open the manual valve 3, the mixture flows through the discharge material pipeline and enters the filter device 7 under the delivery of the peristaltic pump 6, of which the peristaltic pump 6 is Ponndorf P-classic 50twin, the filter device The size of the screen mesh is 1mm / 18 mesh; the filtered mixed material is sent to the nozzle 8, and the decorative paper (base paper unit weight 70g / ㎡) is sandblasted on one side, and the excess mixed material is returned to In the auxiliary glue storage 10, the liquid level controller 9 is used to control the liquid level of the mixed material in the auxiliary glue storage 10, wherein the liquid level controller 9 can choose a tuning fo...

Abstract

The invention belongs to the technical field of mechanical equipment and relates to production equipment of wear-resistant paper, in particular to alundum powder blasting equipment for wear-resistant paper. The alundum powder blasting equipment for wear-resistant paper comprises an alundum powder blasting system and a glue storage system. According to the invention, a single-side powder blasting technology is adopted, so that the problem of template damages can be solved effectively; liquid resin and alundum powder are mixed in a sand blasting process, so that the alundum powder is easier to disperse uniformly; and in addition, the stability is better by combination of the resin and the alundum powder, so that the alundum powder is difficult to fall in a production process. A peristaltic pump is used to control the material flow to guarantee the stability of the entire sand blasting process; a filter device is used to make a sand-blasted paper face finer and more uniform; and an automatic material replenishment system is adopted to realize the control on materials in an auxiliary glue storage device by using a liquid level device. Furthermore, the wear-resistant paper produced by the alundum powder blasting equipment is higher in clarity compared with the common wear-resistant paper, and can be timely regulated in wear resistance according to production requirements, thus the alundum powder blasting equipment is stronger in production adaptability.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to wear-resistant paper production equipment, in particular to wear-resistant paper corundum powder spraying equipment. Background technique [0002] At present, the wear-resistant paper used by most laminate flooring manufacturers is ordinary wear-resistant paper. This kind of wear-resistant paper is produced by mixing paper fiber and a certain amount of corundum powder in the paper production process. For example, Chinese patent CN100497822C discloses A kind of surface wear-resistant paper, the wear-resistant paper contains cellulose pulp mixture, white corundum (Al 2 o 3 ) compounded with wear-resistant fillers and additives, it has the advantages of high transparency, high wear resistance and long service life. However, this kind of wear-resistant paper still has certain defects: First, the wear-resistant paper is produced by mixing papermaking fibers and corundum ...
