Board production process and modification of inorganic glue

Abstract

The invention provides a board production process and modification of inorganic glue. A spreading machine spreads a face material to a spreading machine conveying belt; the inorganic glue is conveyed to a coating machine through a pipeline at the lower end of a glue hopper; the coating machine conveys the inorganic glue to a glue spraying device; the glue spraying device is provided with a plurality of spraying holes; the inorganic glue is coated to a single board at the upper end of the conveying belt through the spraying holes; an unreeling machine paves the reeled single board; a thickness-fixed roller rolls on the single board; the glue spraying device, the unreeling machine and the thickness-fixed roller apply glue, unreel and roll synchronously, and the above pavement sequence is the basic odd number pavement; and after the face board is paved, the thickness-fixed roller rolls evenly to fix the thickness, then short cutting and prepressing are conducted according to the board length, the prepressing is cold pressing and is 0.1-1 MPa, the cold pressing time is 3-24 hours, and thus molding is achieved. The prepared product does not contain formaldehyde and has the inorganic glue with good bonding strength, the problems that in the production of plywood, the process is complex, energy consumption is high, pollution is high, and formaldehyde in finished products is released are solved, the procedure is simplified, the production efficiency is high, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of industrial analyzer equipment, in particular to a plate production process and modification of inorganic glue. Background technique [0002] Panels are usually manufactured as flat rectangular building material panels of standard sizes for use as wall, ceiling or floor elements. It also refers to forged, rolled or cast metal plates. Divided into thin plate, medium plate, thick plate, extra thick plate, usually made into flat rectangular building material plates of standard size. According to the material classification, the board can be divided into two categories: solid wood board and wood-based board; according to the shape classification, it can be divided into solid board, plywood, fiberboard, decorative panel, fireproof board and so on. [0003] The plywood is also a plywood, which is a three-layer or multi-layer board-like material made of wood sections that are peeled into veneers or sliced ​​into thin woo...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the problems of the prior art, the present invention provides a production process for boards and the modification of inorganic glue, which solves the problems of complex processes, high energy consumption, high pollution and formaldehyde release in finished products in the production of plywood. It does not contain formaldehyde, but also has good bonding strength, and the price is extremely low, the market competitiveness is strong, and the inorganic glue is easy to promote and sell. When the plate is processed, the inorganic glue is sprayed, unwinding, and rolling are completed simultaneously, the process is simplified, and the production efficiency is higher. , reduced energy consumption
