Abstract
The present invention produces shaving board with corn stalk and root as main material and through the steps of shredding, shaving, wind selection, sieving, drying, mixing with glue, spreading, hot-pressing, edge sawing and others. Producing one cubic meter of board needs corn stalk and root 1,100-1,300 Kg and sodium chloride 2-3 Kg. The present invention makes it possible to use agricultural residue to produce shaving board with excellent performance.
Description
The present invention relates to manufacture method of particieboard and products thereof, particularly a kind of is the product that primary raw material is made the method for particieboard and adopted this method to make with the corn rhizome.
In recent years, the production development of countries in the world particieboard is rapid, and the U.S. produces 600 myriametres per year
3Japan, West 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, and 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: a kind of raw material wide material sources are provided, price is low, promptly providing and adopting the corn rhizome is that primary raw material comes the wood shavings of replacing wood to produce the manufacture method of particieboard, alleviate the timber resources deficiency, keep the ecological balance, keep environment, and by the particieboard manufacturing cost of this method manufacturing reduce significantly, manufacturing process is simple, various performance indications and surface quality are better than particieboard.
The present invention is achieved by following manner: a kind of manufacture method of particieboard, it is characterized in that: adopting the corn rhizome is primary raw material, successively with chopping, flaking, selection by winnowing, screening go soil, polishing, drying, impregnation glue mixing, mat formation, hot pressing, saw frontier inspection are tested etc., and operation is finished, making every cubic metre of particieboard primary raw material corn rhizome is 1100～1300 kilograms, 130～150 kilograms of urea-formaldehyde glues, 2～3 kilograms in sodium chloride, wherein:
A, chopping operation are the corn rhizome to be cut into 10～25 millimeters short-movie;
B, flaking operation are that the material that will be cut into short-movie becomes 0.15～0.5 millimeter thin slice with the flaking power blader;
C, selection by winnowing operation are with the marrow of the sheet material of above-mentioned plane in blower fan is removed the corn rhizome;
It is the defective material of bulk is separated with the qualified material of fritter and to remove impurity such as soil etc. with vibratory sieve that geotechnological preface is gone in D, screening;
E, polishing operation are that the defective material of isolated bulk in the D operation is become the qualified material of fritter through sending sander further to polish;
F, drying process are the fritter qualified material of going native fritter qualified material and polishing to be processed into through screening in D, the E operation to be sent into drying machine through air blast together carry out drying; The drying machine baking temperature is 130 ± 5 ℃, and dried material water ratio is below 5%;
G, impregnation glue mixing operation are the materials that drying is good, through the metering of metering feed bin, add amine-oxides 1～3% in the urea-formaldehyde glue and carry out glue mixing, and glue consumption is 130～150 kilograms every cubic metre, and the solids content of glue is 60～64%;
H, the operation of mating formation are to mat formation with the spreading machine of airflow pavement machine or other form through the material of impregnation glue mixing;
I, hot pressing process are that the material that will pave carries out hot pressing with hot press, and hot pressing temperature is 140～160 ℃, and the time is 0.5min/mm, and maximum pressure is 2.5N/mm
2
J, saw limit operation are on request with sheet material saw limit, check, the then warehouse-in of sawing machine with hot forming.
The particieboard of Sheng Chaning according to the method described above.
The present invention compares with existing particieboard, has following characteristics:
1, because the present invention adopts air blast to remove the marrow of corn rhizome, product quality is improved greatly, do not add waterproofing agent, the water sucting thickness dilation is 5.3%, and nail-holding ability is 1690N, all is better than the particieboard that wooden flake board and other non-wooden material make.
2, meet the requirements by the national standard detection, specific targets are:
1., density is 0.85kg/cm
3
2., MOR is 14.2MPa;
3., the water sucting thickness dilation is 5.3%;
4., moisture content is 5.4%;
5., internal bond strength is 0.22MPa;
6., holding gong nail power is 1690N (vertical panel face).
3, manufacture method of the present invention is simple, and various performance indications and surface quality are better than existing wooden and non-wood particleboard, low cost of manufacture, the raw material wide material sources all are agricultural wastes, have solved the problem of timber resources deficiency, keep the ecological balance, keep characteristics such as environment.
Further specify technical solution of the present invention below in conjunction with embodiment.
