Abstract
Raw materials of non-wood freight tray of the present invention is selected for use and drawing method, relates to non-wood plant stalk imitation wood manufacturing, promptly is to select for use Sunflower Stalk to do raw material, and a kind of straw of replacing wood compacting non-wood freight tray is selected for use and drawing method.The present invention effectively improves pallet intensity, reaches the quality requirement of various freight pallets and storage bracket tray, in the concrete practice specification detailed description is arranged.
Description
Technical field:
Raw materials of non-wood freight tray of the present invention is selected for use and drawing method, relates to non-wood plant stalk imitation wood manufacturing, promptly is to utilize a kind of straw of Sunflower Stalk replacing wood compacting freight pallet to select for use and drawing method.
Background technology:
In recent years, the technology of utilizing stalk to make sheet material for raw material is constantly released, but as if all there are many defectives: composite rice straw board and manufacturing process thereof, (CN1294094) it is with straw, husk, stalks etc. are wherein a kind of to be major ingredient, be equipped with light burnt powder, modifying agent, stir in the footpath, injection molding adds glass fibre, the oven dry demoulding, operations such as curing are made sheet material, though the sheet material of this explained hereafter can the instead of wood plate material, but because of a large amount of industrial chemicals and glass fibres of using cause its product having some problems aspect the environmental protection, secondly product spontaneous curing moulding, timber intensity is limited.Cement gypsum reed fiber composite board and production method thereof (CN1154896) are major ingredient with the reed fiber, are cementing agent with the cement gypsum, and it is heavier that the sclerosis back forms sheet material its product self, and intensity is limited.Strong board (CN12621717) is earlier magnesia, and magnesium silicate mixes and stirred 10-40 minute, uses bamboo, reed, cornstalk, axis such as palm leaf are woven into the net sheet, do the middle level skeleton with glass fabric, flatten the natural moulding in back, its product strength is not high, and yet not environmental protection of product.
Summary of the invention:
The present invention be directed to the production technology of the said goods and many defectives that technical formula exists, a kind of raw materials of non-wood freight tray of design is selected for use and drawing method, promptly is to select for use Sunflower Stalk to do raw material replacing wood compacting freight pallet.At first every Sunflower Stalk is cut into 1300mm from root to the tip, remaining part is ground into the particle of 1-20mm, then the long stalk section of 1300mm on homemade special equipment to cuing open, make one divide two halves, remove the crust core of emedullating with homemade special equipment afterwards, and it is rolled into sheet, gluing on glue spreader then, the particle that is ground into 1-20mm is put into the mixer applying glue to be stirred, carrying out assembly afterwards in pallet is framed mats formation, particle after the Shi Yaoxian that mats formation stirs applying glue is mated formation and (is wanted the pressurization of Bian Pu limit to make its compacting when square pin is being mated formation) in framed interior nine the square pin of pallet then the stalk sheet behind the gluing to be arranged the staggered method of laying repeatedly of longitudinal mode by cocurrent and parallel to carry out assembly and mat formation, be that first parallel longitudinal is arranged laying ground floor stalk sheet, laterally be arranged in parallel then second layer stalk sheet is laid on the framed interior ground floor stalk sheet, be that the vertical one deck of one deck is horizontal, want crisscross several layers (universal standard pallet is generally laid the 8-20 layer) the freight pallet external form universal standard size of laying repeatedly at 850mm * 850mm * 20mm length * wide * thickness of slab between layer and the layer, between 1200mm * 1016mm * 20mm length * wide * thickness of slab, side's pin height is generally between 80mm-120mm, except the special tray, after having laid last one deck stalk sheet, each assembly repaves the upper layer material, cover template then, through pressurized, heated, the moulding depanning, each operation production Sunflower Stalk freight pallet of burr is removed in the cooling back.
Raw materials of non-wood freight tray is selected for use and drawing method, be to dewater by raw material, Sunflower Stalk is cut off film-making, and Sunflower Stalk is pulverized, stalk sheet gluing, the particle applying glue is stirred, surface material cutting brush coating is laid, and particle and stalk sheet assembly are mated formation, the heating pressurization, each operation composition of burr is removed in the depanning cooling, it is characterized in that:
One, Sunflower Stalk processed (air dry and artificial drying) makes water content＜5%.
Two, Sunflower Stalk film-making and pulverizing, at first every Sunflower Stalk is cut into the long stalk section of 1300mm from root to the tip, afterwards on homemade special equipment to cuing open, make one divide two halves, then at the homemade special equipment crust that gets on, the core of emedullating, and semi-circular stalk section is rolled into sheet, remaining part is ground into the particle of 1-20mm with pulverizer, changes next procedure then over to.
Three, stalk sheet and particle applying glue, process is cut off, and to cuing open, the core of emedullating is rolled into stalk sheet gluing on glue spreader of sheet, put into mixer applying glue stirring 5-10 minute being ground into the 1-20mm particle, sizing material can use urea-formaldehyde resin adhesive, and solid content 60%, resin added are the 8%-14% of blank net weight, also can use modified urea glue, promptly be to add 20% melamine resin adehsive with 80% urea-formaldehyde resin adhesive, be mixed into modified adhesive, resin added is similarly the 8%-14% of blank net weight.
Four, surface material cutting brush coating, surface material select 70-220 gram corrugated paper, at first corrugated paper are cut into 1220mm * 1016mm length * wide or other overall dimensions by the pallet overall dimensions that will produce, then brush coating or spray glue.
Five, stalk sheet and particle assembly are mated formation, at first the particle that stirs through applying glue is put into nine framed square pin of pallet, pressurization simultaneously makes the particle shop real, arrange the laying ground floor press cocurrent and parallel through the stalk sheet of gluing then, be parallel longitudinal arrange the stalk sheet be laid on pallet framed in, the laying second layer subsequently laterally is arranged in parallel, wanting crisscross between layer and the layer lays repeatedly, lay the 8-20 layer as requested, treat last one deck stalk sheet lay finish after above that layer overlay cut out 70-220 gram corrugated paper behind the brush coating, spread template then, change press over to.
Six, heating pressurization, common artificial plate pressing machine principle is adopted in pressurization, from making special equipment, each compacting 1-10 piece pallet, add thermal recovery heat-conducting oil furnace or plain cylindrical furnace temperature 180-210 degree, pressure 900-1200 ton, hot pressing time 10-30 minute, be cooled to normal temperature after the pallet depanning and remove burr, promptly produce qualified products.
Good effect of the present invention is to utilize Sunflower Stalk replacing wood compacting freight pallet, turns waste into wealth.Adopt the Sunflower Stalk particle to do pallet side's pin blank, be convenient to mat formation, adopt stalk sheet cocurrent and parallel to arrange, the crisscross assembly method for paving of laying repeatedly, improve pallet intensity, adopt 70-220 gram corrugated paper to do surface layer above the pallet, promptly gain in strength and improve surface smoothness, adopt veneer and blank one-shot forming technique simultaneously, reduce manufacturing cost.
