Abstract
The invention discloses a method for manufacturing a plywood and a plastic-wood composite with manioc waste. The method comprises the steps that the manioc waste subjected to clear water spraying treatment is cooled to 20-25 DEG C, poured into a culture solution with microorganisms, mixed fully and cultured for 2-4h at 25-45 DEG C; alkali is added to liquid containing the microorganisms; a pH value is adjusted to be 8.2-9.5; the liquid is mixed fully and immersed for 10-20min; the waste is placed into a disinfectant to be immersed for 10-40min and stirred fully; the waste is dried and mixed with an adhesive; a sizing amount is 8-11wt% of the dried waste; a plate blank is subjected to paving, prepressing and hot press molding; and the plywood and the plastic-wood composite are obtained. Compared with the prior art of producing the plywood with the manioc waste, the method has the benefits that the consumption of the adhesive is saved, the produced plywood is high in static bending strength, the plate density is high, and the screw holding capability is improved.
Description
Technical field
The invention belongs to the manufacturing field of glued board, be specifically related to a kind of technical scheme of utilizing manioc waste to make glued board.
Background technology
In Guangxi of China, there is a large amount of starch factories in the province such as Guangdong, Hainan, can produce a lot of manioc wastes when coming processing starch with cassava.Many raisers often are used for doing feed to manioc waste, and the main component of manioc waste is starch, cellulose and lignin, and a small amount of protein, and the raiser mixes manioc waste to boil as feed with some feeds and uses.Feed pigs or manioc waste and feed hodgepodge are fed pigs with manioc waste, not only tired expensive, only can feed oneself, not only the nutrition digestion absorptivity to manioc waste itself is extremely low, and pig is not liked to eat, poor growth, and staple length is lost more than gain.
Not only at home, in south east asia, a large amount of cassava processing factories is arranged also.Just nearly 100,000 tons of manioc waste factories that the need of abandoning more than large-scale cassava processing factory of several families every year of Indonesia are processed, for seeking to process the effective way of these waste materials, Indonesia cassava processing factory proposes to produce with manioc waste the suggestion of wood-based plate to middle side, entrust Jiangxi building wood-based plate research institute to carry out pilot production research by China National Machinery and Equipment Import and Export Corporation." development of manioc waste particieboard " that should deliver in the second phase in 1999 " BUILDING ARTIFICIAL BOARDS " magazine eastwards of Jiangxi building wood-based plate research institute put down in writing the correlative study conclusion:
" manioc waste mostly is fine particulate after loosening out; powder-material is many; undesirable for the production of its form of particieboard; powder-material suction glue amount is large, and resin added is up to 15%, because fiber content in manioc waste is few; fiber is short; the MOR value of product is lower, only has by suitable increase resin added and the density that improves sheet material this index is improved, to reach national particieboard standard-required.When density less than 0.75g/cm
3The time, its MOR value is difficult to satisfy user's instructions for use lower than GB 30～40%.”
For the short problem of its fiber, this article proposes to mix other long fibered raw materials in manioc waste such as bagasse carries out modification to manioc waste:
" can evenly mix in process of production with manioc waste in order to make other fibrous material that mixes, especially by Solution on Air Forming Equipment, its compound can be paved into evenly, the slab of symmetrical grading structure, the selected performances such as admixture material unit weight should approach with manioc waste, consider the condition in cassava producing region, general cassava producing region is also the area that grows cane in a large number, the bagasse of abandoning more than sugar refinery is the good material of producing particieboard, unit weight and manioc waste approach, in bagasse, fiber is long, content is high, can make up to a certain extent manioc waste deficiency in this respect, can greatly improve the mechanical property of product.On the other hand, some bagasse of admixture need not extra increasing or change equipment in manioc waste in the raw material treatment process, and production process is constant.In experimentation, because being subjected to the restriction of time, raw material quantity, we have mainly carried out the test of admixture 50% wooden wood wool, and the pressed sheet the performance test results sees Table 5.As can be seen from Table 5, admixture part fibrous material can make the MOR of product and hold screw power and significantly improve ".
By above-mentioned material as can be known, manioc waste is not the appropriate materials of producing sheet material, and the inventor has developed in repetition test manioc waste is carried out pretreatment, produces the technical scheme of sheet material.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of utilizing manioc waste to make glued board, Wood plastic composite, too many to solve the manioc waste opaque that occurs in prior art manioc waste production particieboard, Wood plastic composite product, inhale the large problem of glue amount, belong to the plywood making technical field.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of method of utilizing manioc waste to make glued board, Wood plastic composite, it comprises the steps:
(1) manioc waste after processing with clear water spray be cooled to pour into after 20～25 ℃ and cultivate the nutrient solution that microorganism is arranged, and fully mix, and 25～45 ℃, cultivate 2～4 hours;
(2) with the liquid that contains microorganism after step (1) processing, add alkali to adjust pH value to 8.2～9.5, fully mix, soaked 10～20 minutes;
(3) residue after step (2) processing being put into thimerosal soaked 10～40 minutes and fully stirred;
(4) the residue oven dry after step (3) is processed, admix adhesive, resin added for oven dry after 8～11wt% of residue, with the plate embryo mat formation, precompressed, hot-forming glued board, the Wood plastic composite product of namely getting.
In step (1), microorganism used is Actinobacillus succinogenes or Rhizopus oryzae or Candida.
Actinobacillus succinogenes is preferably Actinobacillus succinogenes ATCC55618.
The Rhizopus oryzae manioc waste is preferably Rhizopus oryzae ATCC20344.
