Embodiment 1

[0051] Plywood production process: add 135 parts of magnesium oxide to 100 parts of magnesium chloride, add 1 part of additives and stir, the order of adding the additives is sodium hexametamate, sodium phosphate, ferrous sulfate, phosphoric acid, and then add 20 parts Nano-scale silica fume, 40 parts of adhesive, 30 parts of wood flour, and 1 part of water reducer are stirred for 2-15 minutes to form a viscous glue for use.

[0052] Carry out cutting according to the length of the raw material processed by the plate, process it into a veneer with the required specification thickness with a veneer rotary cutting machine, the specification is 0.3-6mm, roll it into a veneer roll with a diameter of 1.2m or less with a coiler, and wait Use, the paving machine 6 spreads the surface material on the paving machine conveyor belt 8, the inorganic glue is transported to the spraying machine 10 through the pipeline at the lower end of the glue hopper 2, and the spraying machine 10 transpo...

Embodiment 2

[0054] Cement formwork production process: add 135 parts of magnesium oxide to 100 parts of magnesium chloride, add 1 part of additives and stir, the order of adding the additives is sodium hexametamate, sodium phosphate, ferrous sulfate, phosphoric acid, and then add 6 Mix 1 part of nano silica fume, 20 parts of adhesive, 15 parts of wood flour, and 1 part of water reducer for 2-15 minutes to form a viscous glue for use.

[0055] The fiber woven or non-woven surface material is coated with a plastic non-woven machine to form a cement formwork panel. The fiber woven or non-woven surface material on the back of the panel is raised by a raising machine to increase the bonding strength. The inorganic glue is passed through the glue hopper. 2 The pipeline at the lower end is transported to the spraying machine 10, and the spraying machine 10 transports the inorganic glue to the glue spraying device 11. The glue spraying device 11 is provided with several spray holes 15, and the ino...

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...
