Abstract
The production method of shaving board by adopting wheat straw, rice straw and reed as main material mainly includes the following procedures: sorting wheat straw, cutting, rubbing, grinding, drying, sieving, mixing with glue, spreading, hot-pressing, sawing edge, cooling, sand-polishing, grading and packing, etc..Said production method is simple and easy to implement, and its production cost is low, and the preformance indexes and surface quality of said invented product can reach the standards of GB/T4897-92.
Description
The present invention relates to the manufacture method of wood-based plate, particularly a kind of is the manufacture method and products thereof of the particieboard of raw material with wheat straw, reed, straw.
In recent years, the production development of countries in the world particieboard is rapid, the U.S. produces 600 myriametres 3 per year, Japan, Germany, states such as the Soviet Union also are doubled and redoubled, usually particieboard production accounts for 4% of wood-based plate output, especially West Europe accounts for 78%, but the minimizing gradually with human resource of improving constantly along with human industrialization degree, fewer and feweri as the forest tree resource of producing wood shavings, this has just proposed to produce the raw material sources problem of particieboard, because the forest reserves reduce gradually, raw material sources are restricted, cause cost to improve, people have developed and have adopted other raw material to substitute method and technology that wood shavings are produced various sheet materials for this reason, a kind of method of making sheet material with corn stalk is disclosed for Chinese patent CN87103594.A number in the recent period, though the sheet material of this method manufacturing is compared with particieboard, surface smoothness is good, MOR and plane tensile strength increase, but it still can not satisfy the fundamental characteristics as construction material fully: i.e. light weight, high strength and high rigidity, dimensional stability is good, corrosion resistant and anti-combustion, sound-insulating and heat-insulating, nontoxic etc.Its manufacturing cost is higher simultaneously, complex process.
The objective of the invention is: provide a kind of raw material source wide; agricultural production residue (wheat straw; straw; reed etc.) make the method that raw material are produced particieboard; to alleviate the timber resources deficiency; keep the ecological balance; the protection environment; and particieboard with this method production; manufacturing cost reduces greatly, and manufacturing process is simple, and adopts a kind of special adhesive aborning; the raw material sources of this adhesive are also very wide; thereby the integrated cost of making particieboard is further reduced, be not higher than the wooden flake board that utilizes common urea-formaldehyde glue to make, simultaneously; the particieboard that utilizes this method to produce does not need to add in addition any waterproofing agent; its thickness swelling rate satisfies the GB/T4897-92 standard-required, and in addition, this particieboard in use; do not have pernicious gas generations such as free formaldehyde, do not have air pollution.
The present invention is achieved by following manner: a kind of manufacture method of particieboard, it is characterized in that: the employing wheat straw is a primary raw material, successively with wheat straw sorting, wheat straw cut off, gentlely rub polishing, drying, screening, glue mixing with the hands, mat formation, operations such as hot pressing, the cooling of saw limit, sanding, the packing of grading finish, making every cubic meter particieboard primary raw material wheat straw is that 800-1000 kilogram, glue are the 20-28 kilogram, and wherein each operation is:
A, wheat straw sorting operation are that wheat straw will carry out sorting before processing, remove impurity (as stone, sand, metal object etc.) and rotten wheat straw;
B, wheat straw cut off operation and are with hay cutter or cut the wheat straw sheet that the reed machine is cut into wheat straw the 10-40 millimeter;
C, gentle stranding polishing operation are with beating crusher or gentle stranding machine the wheat straw sheet to be smashed to be separated into fibre bundle;
D, drying process are to adopt floated drying machine of hot blast or contact roller dryer to carry out drying, baking temperature 50-200 ℃, decide according to the first moisture content of wood shavings drying time, common dried wood shavings moisture content is no more than 13%, spring weather relatively dry, be not higher than 13% as the moisture content of wheat straw and can not carry out drying and directly enter subsequent processing;
E, screening operation are with the classification of sieving of circular vibrating screen or rectangle vibratory sieve with dried shavings raw material, be generally the sieve of three layers of screen cloth, following layered material after the screening is that fines by 0.125 millimeter sieve aperture is as the no glue wood shavings of two tables, middle material is that the inferior fines by 0.25 millimeter aperture has the glue wood shavings as two skins, upper layer material be stranded in 0.25 millimeter aperture by 1.00 millimeters apertures coarse fodder as the sandwich layer wood shavings, the upper epidermis material is that the aniseed that is stranded in 1.00 millimeters apertures returns the C operation and carries out broken through beating crusher again;
F, glue mixing operation are to adopt twin shaft low speed glue mixer or single shaft high speed glue mixer that adhesive evenly is sprayed on the surface of wood shavings, and resin added is 20-28kg/m
3Because of outer wood shavings are more tiny, the surface area of Unit Weight wood shavings is bigger, and glue consumption is more, sandwich layer wood shavings then glue consumption are less, usually require the respectively glue mixing of outer wood shavings and sandwich layer wood shavings in the production, even for guaranteeing glue mixing, spray on the wood shavings after should making the glue atomizing during glue mixing, and to stir, make between wood shavings fully contact friction, but will prevent that material from heating up, cause that adhesive solidifies in advance and influences the intensity of plate;
G, the operation of mating formation are that the top layer wood shavings of the outer wood shavings after the glue mixing, sandwich layer wood shavings and not glue mixing are required to mat formation into slab successively in order, in concrete the production various ways is arranged, as be successively sandwich layer wood shavings, outer wood shavings, top layer wood shavings assembly form and the outer wood shavings after the glue mixing and the sandwich layer wood shavings after the glue mixing are mixed after the assembly form of mating formation again;
H, hot pressing process are to finish on the single or multiple lift hot press, and hot pressing temperature is 140-190 ℃, and hot pressing time is 10-30s/mm, and unit pressure is 2.5-3.0MPa, adopt three sections pressuring methods;
I, saw limit refrigerating work procedure are to be sawn into certain length and width by dimensions with edge saw, and are cooled to room temperature;
J, sanding operation are to adopt sander to carry out sanding, with the fineness that guarantees product surface and enough working strength and the thickness deviation that makes product within the scope of standard code;
K, the packaging process that grades are the sheet material of producing through above-mentioned each operation to be tested grade, then the packing warehouse-in.
The particieboard of Sheng Chaning according to the method described above.
In addition, present technique can also adopt the single variety of wheat straw, straw, reed etc. or mix by a certain percentage, and just the sorting of raw material processing is different, and other operation is basic identical.
The particieboard that the present invention makes is through check, and its every physical and mechanical property reaches the GB/T4897-92 standard, and does not have the pollution of free formaldehyde.
The present invention compares with prior art; it is simple to have manufacture method, and every performance indications and surface quality reach GB/T4897-92 standard (do not need to add any waterproofing agent, its water sucting thickness dilation satisfies above-mentioned GB/T4897-92 standard); there is not the pollution of free formaldehyde; and performance indications are better than existing wooden and non-wood particleboard, low cost of manufacture, and the raw material source is wide; all be agricultural wastes; solved the problem of timber resources deficiency, kept the ecological balance, characteristics such as protection environment.
