Embodiment 1

[0055] Plywood production process: add 90kg of mixed solution to 100kg of magnesium oxide, add 0.6kg of modifier and stir, the modifier is mixed with water glass, phosphoric acid, citric acid, trisodium phosphate and boric acid, and then add 20 Parts of nano-scale silica fume, 40 parts of adhesive, 30 parts of wood flour, and 1 part of water reducer are mixed for 2-15 minutes to form a viscous glue, ready for use.

[0056] Cut according to the length of the raw material for sheet metal processing, and use a veneer rotary cutter to process it into a veneer with a required thickness of 0.3-6mm, and use a rolling machine to roll it into a veneer coil with a diameter of less than 1.2m. For use, the paving machine 6 lays the surface material on the conveyor belt 8 of the paving machine, and 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 then transports the inorganic glue to the glue...

Embodiment 2

[0058] Cement template production process: add 50kg of mixed solution to 80kg of magnesium oxide, add 0.6kg of modifier and stir, the modifier is mixed with water glass, phosphoric acid, citric acid, trisodium phosphate, boric acid, and then added 6kg of nano-silica fume, 20kg of adhesive, 15kg of wood flour, and 1kg of water reducing agent are stirred for 2-15 minutes to form a viscous glue, ready for use.

[0059] The fiber woven or non-woven surface material is filmed by a plastic borderless machine to form a cement template 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, and 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 then transports the inorganic glue to the glue spraying device 11. The glue spraying device 11 is provided with a number of spray holes 15, and the inorg...

Embodiment 3

[0061] Cement template production process: add 100kg of mixed solution to 80kg of magnesium oxide, add 0.6kg of modifier and stir, the modifier is mixed with water glass, phosphoric acid, citric acid, trisodium phosphate and boric acid, and then added 15 parts of nano-silica fume, 45 parts of adhesive, 18 parts of wood flour, and 1 part of water reducer are mixed for 2-15 minutes, and then a viscous glue is formed, ready for use.

[0062] The adhesive film paper and dry veneer are hot-pressed with a dispersing resin to form a specification surface material, the specification is 36-48 inches, cut according to the length of the raw material for sheet processing, and processed into the required specification thickness with a veneer rotary cutter The size of the veneer is 0.3-6mm, and it is rolled into a veneer roll with a diameter of less than 1.2m by a rolling machine, and it is ready for use. The paving machine 6 spreads the surface material on the conveyor belt 8 of the paving ...

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 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 production process of a plate and modification of an inorganic glue. Background technique [0002] Panels are typically made into standard-sized flat rectangular panels of building material that are used as components for walls, ceilings or floors. Also refers to forged, rolled or cast metal plates. Divided into thin plate, medium plate, thick plate, extra-thick plate, usually made into standard size flat rectangular building material plate. According to the material classification, the board can be divided into two categories: solid wood board and wood-based board; according to the molding classification, it can be divided into solid board, plywood, fiberboard, decorative panel, fireproof board and so on. [0003] Plywood is also called plywood, which is a three-layer or multi-layer board material made of wood segments that are cut into veneers or sliced ​​into v...
