A kind of production method of dalle
Technical field
The present invention relates to sheet material manufacturing technology field, particularly relate to the production method of a kind of dalle.
Background technology
In sheet material manufactures, particieboard is applied to produce and the every field of life by substantial amounts of, the particle that particieboard is generally adopted timber or other ligno-cellulosic materials are made, the wood-based plate composed under heating power and pressure effect after applying adhesive. Wood particle is only had to be packed together by the outward appearance of the particieboard of this kind of technique making, it does not have decorative pattern attractive in appearance.
Summary of the invention
The technical problem that present invention mainly solves is to provide the production method of a kind of dalle, and described production method comprises the steps:
Choose the branch of diameter��3cm,
Branch is carried out at normal temperatures,
Adopt hogger that the branch after cleaning is carried out chopping process, form branch granule,
Being put in jet drier by branch granule after chopping and be dried, temperature controls at 120 DEG C, and drying time is 30 minutes, relative air humidity is 8%-12%, hot-air jet velocity controls at 13 meter per seconds, and the moisture content of dried branch is 13%-15%
Branch granule after chopping is carried out taper thread grinding, the sharp portion on wood grain is ground off,
Screened by mesh screen, choose the wood grain of diameter��2cm after screening,
According to weight ratio, 50 parts of wood grain, 80 parts of dry sprills resins and 50 parts of coconut fibre are stirred formation mixture,
Said mixture is uniformly poured into pressing in board mould, makes wood grain and long fibre can be uniformly distributed in melten gel, heating 1 hour at the temperature of 140-150 DEG C of degree,
Described plate carrying out after natural cooling hot pressing, forms slab, the thickness of slab is 0.5-1.5cm, and in the process of hot pressing, wood grain can be extruded, and exposes wood grain, and the plate surface after molding forms the surface of round point shape wood-grained shape,
Described slab carries out saw limit, sanding processes, and finally obtains finished product.
The invention has the beneficial effects as follows: the production method of dalle of the present invention; by cutting after branch is dried; form wood grain; by wood grain with there is long stapled coconut fibre and dry sprills resin is sufficiently mixed rear hot pressing; owing to, in the process of hot pressing, wood grain can be extruded, and exposes wood grain; plate surface after molding forms the surface of round point shape wood-grained shape, improves the aesthetics of decorative panel.
Detailed description of the invention
By describing the technology contents of the present invention, structural feature in detail, being realized purpose and effect, it is 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 carried out at normal temperatures.
Adopt hogger that the branch after cleaning is carried out chopping process, form branch granule.
Branch granule after chopping is put in jet drier and is dried, temperature controls at 120 DEG C, and drying time is 30 minutes, and relative air humidity is 8%-12%, hot-air jet velocity controls at 13 meter per seconds, and the moisture content of dried branch is 13%-15%.
Branch granule after chopping is carried out taper thread grinding, the sharp portion on wood grain is ground off.
Screened by mesh screen, choose the wood grain of diameter��2cm after screening.
According to weight ratio, 50 parts of wood grain, 80 parts of dry sprills resins and 50 parts of coconut fibre are stirred formation mixture, and described dry sprills resin includes the weight ratio epoxy powder more than 70%, and wood grain and coconut fibre mix, improve the toughness of sheet material and hardness.
Said mixture is uniformly poured into pressing in board mould, makes wood grain and long fibre can be uniformly distributed in melten gel, heating 1 hour at the temperature of 140-150 DEG C of degree.
Described plate carrying out after natural cooling hot pressing, forms slab, the thickness of slab is 0.5-1.5cm, and being pressed onto thickness is 1-1.5cm, by some chunk of wood granule crimp, wood grain can be made to expose.
Described slab carries out saw limit, sanding processes, and finally obtains finished product.
The production method of dalle of the present invention; by cutting after branch is dried; form wood grain; by wood grain with there is long stapled coconut fibre and dry sprills resin is sufficiently mixed rear hot pressing; owing to, in the process of hot pressing, wood grain can be extruded, and exposes wood grain; plate surface after molding forms the surface of round point shape wood-grained shape, improves the aesthetics of decorative panel.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention to make or equivalence flow process conversion, or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
