A kind of production method of dalle
Technical field
The present invention relates to sheet material manufacturing technology field, relate in particular to a kind of production method of dalle.
Background technology
In sheet material is manufactured, particieboard is by a large amount of every field of producing and living that is applied to, and the particle that particieboard generally adopts timber or other ligno-cellulosic materials to make, applies the wood-based plate composing under heating power and pressure-acting after adhesive.The outward appearance of the particieboard of making by this kind of technique only has wood particle to be deposited in together, there is no decorative pattern attractive in appearance.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of production method of dalle, and described production method comprises the steps:
Choose the branch of diameter≤3cm,
Branch is cleaned at normal temperatures,
Adopt hogger to shred processing to the branch after cleaning, form branch particle,
Branch particle after chopping is put into jet drier and be dried, temperature is controlled at 120 ℃, and be 30 minutes drying time, and relative air humidity is 8%-12%, and hot-air jet velocity is controlled at 13 meter per seconds, and the moisture content of dried branch is 13%-15%,
Branch particle after chopping is carried out to taper thread grinding, the sharp portion on wood particle is ground off,
Screen by mesh screen, choose the wood particle of the rear diameter≤2cm of screening,
According to weight ratio, 50 parts of wood particles, 80 parts of dry sprills resins and 50 parts of coconut palm palm fibres are stirred to formation mixture,
Evenly pour said mixture in board mould pressing, wood particle and long fibre can be evenly distributed in melten gel, at the temperature of 140-150 ℃ of degree, heat 1 hour,
Naturally coolingly rear described plate is carried out to hot pressing, form slab, the thickness of slab is 0.5-1.5cm,
Described slab is sawed to limit, sanding processing, finally obtain finished product.
Preferably, described dry sprills resin comprises the epoxy powder that weight ratio is greater than 70%.
The invention has the beneficial effects as follows: the production method of dalle of the present invention; after being dried, branch cuts; form wood particle; by wood particle with there is long stapled coconut palm palm fibre and dry sprills resin fully mixes rear hot pressing; due in the process of hot pressing, wood particle can be extruded, and exposes wood grain; plate surface after moulding forms the surface of round point shape wood-grained shape, has improved the aesthetics of decorative panel.
The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being realized object and effect, be explained in detail below in conjunction with embodiment.
The production method of decorative panel of the present invention comprises the following steps: described production method comprises the steps:
Choose the branch of diameter≤3cm,
Branch is cleaned at normal temperatures,
Adopt hogger to shred processing to the branch after cleaning, form branch particle,
Branch particle after chopping is put into jet drier and be dried, temperature is controlled at 120 ℃, and be 30 minutes drying time, and relative air humidity is 8%-12%, and hot-air jet velocity is controlled at 13 meter per seconds, and the moisture content of dried branch is 13%-15%,
Branch particle after chopping is carried out to taper thread grinding, the sharp portion on wood particle is ground off,
Screen by mesh screen, choose the wood particle of the rear diameter≤2cm of screening,
According to weight ratio, 50 parts of wood particles, 80 parts of dry sprills resins and 50 parts of coconut palm palm fibres are stirred to formation mixture, and described dry sprills resin comprises the epoxy powder that weight ratio is greater than 70%, and wood particle and coconut palm palm fibre mix, improve the toughness of sheet material, and hardness.
Evenly pour said mixture in board mould pressing, wood particle and long fibre can be evenly distributed in melten gel, at the temperature of 140-150 ℃ of degree, heat 1 hour,
Naturally coolingly rear described plate is carried out to hot pressing, form slab, the thickness of slab is 0.5-1.5cm, and being pressed onto thickness is 1-1.5cm, can, by some chunk of wood particle crimp, wood grain be exposed,
Described slab is sawed to limit, sanding processing, finally obtain finished product.
The production method of dalle of the present invention; after being dried, branch cuts; form wood particle; by wood particle with there is long stapled coconut palm palm fibre and dry sprills resin fully mixes rear hot pressing; due in the process of hot pressing, wood particle can be extruded, and exposes wood grain; plate surface after moulding forms the surface of round point shape wood-grained shape, has improved the aesthetics of decorative panel.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
