Description
Technical Field
The invention relates to the field of plate processing, in particular to a panel process for avoiding foam holes on the surface.
Background
Conventional panels are pressed out of face layer slurry and are ready for use after the face layer slurry has cured. The main components of the surface layer slurry are chloride, sulfate, a defoaming agent, wood chips, glass fiber and water. Referring to the attached fig. 2 of the specification, in the conventional panel process, a mold is placed on a production line, and the mold sequentially passes through stations such as blanking, press forming, surface slurry scraping and the like, so that a finally formed panel is located on the mold, and the uppermost layer of the panel is a surface. The reason why small cells are occasionally formed in panels manufactured by the panel process is that the pulp scraping process does not have good gripping skill and the pulp scraping is not compact. Panels with even cells are aesthetically unpleasing compared to a large array of smooth surfaced panels, and these panels with cells are ultimately rejected according to the aesthetic standards of the public.
These rejects are usually discarded and wasted, so there is a strong need in the market for a mature panel process that avoids the formation of foam cells on the panel surface.

As an improvement of the scheme, the thickness of the surface paste is controlled to be 0.5-0.8 mm during the paste scraping in the step b.
As an improvement of the scheme, in the step d, the medium material is pressed into a plate shape through a press roll, the press roll is wound with the glass fiber cloth, and the press roll presses the glass fiber cloth into the medium material along the belt.
The invention has the beneficial effects that: the panel technology is characterized in that surface paste, glass fiber cloth and middle material are sequentially laid on a die, pressure applied during forming of the middle material is ingeniously utilized, so that the glass fiber cloth and the surface paste between the middle material and the die are extruded to form a compact surface, and thus after the middle material and the surface paste are solidified, the plane of the whole panel is flat and smooth.
Drawings
The invention will be further described with reference to the accompanying drawings in which:
FIG. 1 is a schematic view of a panel manufacturing process according to the present embodiment;
FIG. 2 is a schematic diagram of a conventional method of manufacturing a panel.
Detailed Description
Referring to fig. 1 and 2, the present invention is a panel process for avoiding the formation of cells on a surface, generally comprising the steps of:
a. preparing flour paste 3 and a middle material 2;
b. paving the surface paste 3 on the template 1, wherein the upper surface of the template 1 is smooth and flat, and then scraping the paste to uniformly spread the surface paste 3; c. glass fiber cloth is laid on the upper layer of the surface paste 3 and used for enhancing the strength of the surface layer of the panel;
d. the middle material 2 is placed on the glass fiber cloth, then the middle material 2 is pressed and shaped, and the layer of the surface paste 3 is used as the surface of the panel.
The flour slurry 3 contains 30-50% of magnesium oxide, 20-30% of magnesium sulfate, 0.2-0.8% of defoaming agent, 15-20% of stone powder and 20-30% of water. The medium material 2 contains 30-40% of magnesium oxide, 15-20% of magnesium sulfate, 5-10% of wood dust, 15-20% of stone powder and 15-25% of water.
Example 1, batter 3 contains 42% magnesium oxide, 20% magnesium sulfate, 0.2% defoamer, 15.8% stone dust and 22% water. The medium material 2 contains 37% of magnesium oxide, 17.5% of magnesium sulfate, 8% of wood chips, 18.3% of stone powder and 19.2% of water. The defoaming agent is a common product in the market, and a person skilled in the art can select a reasonable brand according to actual conditions, which is not described herein.
The middle material 2 and the flour paste 3 are both made into layers. In a preferable embodiment, the thickness of the surface paste 3 is controlled to be 0.5-0.8 mm during the scraping in the step b, and then the thickness of the surface paste 3 is slightly reduced when the middle material 2 is pressed. And d, pressing the medium material 2 into a plate shape through a press roller, winding glass fiber cloth in the press roller, and pressing the glass fiber cloth into the other surface of the medium material 2 along the belt by the press roller, namely the upper surface and the lower surface of the medium material 2 are both provided with the glass fiber cloth.
