Analysis of the difference and use between veneer hot press and other hot presses

Fixed thickness sanding in front of the thickness: The thickness-corrected sheet usually requires that the thickness difference of the same batch of sheets should be controlled within 0.2mm, and there is no sand mark or wave pattern on the surface of the sheet. No obvious touch by hand or chalk. The surface is uneven, but the thickness of the sheet is allowed to deviate from the nominal thickness. It is usually controlled at 0.5mm.

1. Is there a difference between a plywood hot press and a veneer press?

Plywood hot presses, from a professional point of view, are mainly used in the production of plywood, which is used for hot pressing and gluing. Moreover, if the types of plywood are different, then the performance requirements of the hot press are also different. In addition, this type of veneer press has two types of work: cycle work and continuous work. In terms of composition, there are three main bodies, a control driving part and a heating system.

The veneer hot press is divided into a single-layer hot press veneer and a double veneer, mainly used in furniture factories and secondary processing of wood-based panels. Also, it is mainly used for hot pressing veneers, but not for other purposes.

Therefore, in summary, the two types of hot presses are still significantly different, although they are all hot presses. But you can't confuse them.

2. In the production of wood board, can the hot press used as a veneer press be used?

This problem is not acceptable to us because they are two different hot presses. Unlike the molding press, and under pressure, the former cannot meet the requirements. In addition, we also need to know that for veneer hot presses, the larger the tonnage, the better the veneer effect.

3. Veneer hot press, can it be a single or multi-layer hot press?

Veneer presses have nothing to do with single or multi-layer hot presses. Because they are the specific types of heat presses that are divided according to different standards. Therefore, the veneer press can be a single layer or a plurality of layers.

Surface sanding after veneering: The common equipment for surface sanding is a wide belt sander, usually a three-sand frame, and a rubber sanding wheel or a balloon sanding pad with a lower hardness is used as a sanding head, and 150~240 is installed. No. of fine sandpaper tape. The amount of surface sanding secondary sand should be controlled between 0.1~0.2mm, and the surface water glue paper should be sanded by 80%~90%.
