Description
Technical field
The present invention relates to the production technical field of wood-based plate, be specifically related to a kind of processing method of sugarcane particieboard.
Background technology
The kind of wood-based plate has a lot, and wherein the performance of particieboard and medium density fibre board (MDF) compare favourably, and cost is lower, obtains develop rapidly in China.Because particieboard structure comparison is even, good processability, can be processed into the sheet material of large format as required, is the good raw material of furniture making different size, pattern.Manufactured goods particieboard does not need again dry, and can directly use, sound-absorbing and sound insulation value are also fine.Tradition particieboard is mainly divided into following three kinds: 1) log particieboard: as pine or yate chipboard; 2) agricultural byproducts particieboard: as bagasse particieboard, Flaxboard, cotton stalk particieboard and bamboo shaving board etc.; 3) industrial materials particieboard: as cement-bonded wood chipboard and gypsum particle board etc.Obviously these costs of raw material for the manufacture of particieboard are higher, and as wood planing card, it generally adopts pine or eucalyptus is wooden makes, and not only cost is high but also need a large amount of felling, easily causes ecological destruction; And the raw material such as sugarcane, shive, cotton stalk are generally agricultural by product, although can reduce part particieboard production cost, generally these raw material also have other the processing mode having more value, obviously compare waste for processing particieboard; And the industrial materials such as cement, gypsum particle board particieboard, although cost is low, raw material are easy to obtain, processing technology is more complicated, and quality of finished cannot ensure, and dust is more, easily affects the healthy of workers processing.
Sugarcane is a kind of annual or perennial Perenniporia martius herbaceous plant.Sugarcane is temperate zone and tropical crops, is the raw material manufacturing sucrose, and can refines ethanol as energy substitution product.Containing abundant sugar, moisture in sugarcane, also containing the material such as various vitamins, fat, protein, organic acid, calcium, iron be highly profitable to human metabolism, be mainly used in sugaring, epidermis is generally purple and green two kinds of common colors, also redness and brown is had, but more rare.Sugarcane is the crop that a kind of content of cellulose is very high, can be used for processing artificial boards, but does not have corresponding technology at present.
Summary of the invention
The object of the invention is to: the processing method that a kind of sugarcane particieboard is provided, cost existing for traditional particieboard be high, wastage of material serious, complex process, quality of finished differ and part dust is many to solve, the problem of and ecological disruption large to staff's health threat.
The present invention is achieved by following technical solution:
A processing method for sugarcane particieboard, the method comprises the following steps:
(1) raw material preparation: the fresh cane getting disleaf is some, and by wood chipping equipment by sugarcane oblique slice, the thickness of section is 2-2.5mm;
(2) sieve: divide section by sifted, remove epidermis, median ridge and the dirt in section;
(3) flaking: by the sugarcane section after screening through roller flaker flaking, digging into area is 5-7mm
2sheet wood shavings;
(4) dry: sheet wood shavings being sent into temperature is dry 30-45min in the roller drying machine of 200 DEG C, and drum rotation speed is 45r/min;
(5) store: after the sheet wood shavings after oven dry are separated by cyclone separator, send into warehouse storage;
(6) spice: get sheet wood shavings 43.5-45kg, adhesive 4-5kg after oven dry respectively, waterproofing agent 1-1.5kg puts into agitator and to stir to obtain compound;
(7) mould is entered: pour in the compacting tool set of internal diameter 150cm by the compound after stirring, evenly spreading out to compound is that 16-17.5cm is high;
(8) hot pressing: spreader bar with the pressure of 56MPa, press temperature 160-175 DEG C, pressing down feed speed is 5mm/min, obtains the particieboard that thickness is 3.2-3.5cm;
(9) inspection warehouse-in: quality testing is carried out, warehousing after passing to the particieboard after compacting.
Described step (7) is divided into following steps again:
I () first pours the compound of 1/3 weight in mould, evenly spread out;
(ii) then in the middle part of the mix surface of 1/3 weight, the rounded flower-shaped steel wire of an entirety is placed;
(iii) last being poured into by the compound of remaining 2/3 weight again in mould is also evenly spread out.
Described adhesive is admittedly containing urea-formaldehyde resin adhesive or the phenolic resin glue of thing 11-13%.
In described step (1), wood chipping equipment is with horizontal 30-45 ° of section.
After drying in described step (4), the water content of sheet wood shavings is lower than 5%.
The integral radius R=145-149cm of described steel wire.
Described steel wire gauge of wire used is 2mm.
The invention has the beneficial effects as follows:
Compared with prior art, the processing method of sugarcane particieboard provided by the invention, adopt sugarcane as processing raw material, there is easy acquisition, advantage with low cost, and sugarcane fibre content is many, make the particieboard obtained have higher intensity, not only achieve effective utilization of discarded crop, but also save the use of wood raw material, ecology can not be destroyed because of falling trees; Meanwhile, in particieboard pressing process, in mould, put into the steel wire of reinforcement effect, significantly can promote the physical and mechanical property of finished product particieboard, improve the intensity of finished product particieboard; In addition, wood shavings again after first cutting into slices to raw material, can ensure the greater homogeneity of wood shavings, and then improve surface flatness and the fineness of finished product particieboard.
