Abstract
The invention relates to a shaving board produced through comprehensive utilization of various wastes and a production method of the shaving board, and belongs to the technical field of artificial boards. The product comprises the following components in percentage by weight: 29-31% of saw timber ash, 19-21% of wheat straw, 29-31% of corn stalk and 19-21% of wood chip. The production method comprises the following steps: smashing the wood chip, wheat straw and corn stalk; blending and mixing the broken wood chip, wheat straw and corn stalk obtained in percentage by weight and collected saw timber ash; mixing glue; paving; hot-pressing; final trimming; sanding. Qualified shaving boards can be produced through comprehensive utilization of various wastes, so that the environment can be protected, municipal waste is reduced, and forest resources are protected.
Description
Technical field
The invention belongs to man-made board technology field.
Background technology
Particieboard is by timber or other ligno-cellulosic materials particles, applies the wood-based plate composing under heating power and pressure-acting after adhesive.Particieboard is not only for architectural engineering, and application is also quite extensive in daily life, the huge market demand.Forest reserves appearance is at present burst weary, and particieboard is also the same with solid wood board, and supply falls short of demand.Applicant is located in border area, motherland southwest, and due to social history and the various factors such as economic, cultural, local economy total amount is low, though having enough to eat and wear of the people solved, also not rich.In order to build a well-off society in an all-round way, from local resources, multiple discarded object is reclaimed to processing particieboard, can protection of the environment, reduce municipal refuse, protect forest resources, promote the development of forestry, increase the income of residents.Although at present existing use with 20% timber wood shavings (need timber is broken and obtain after shaving machine wood shavings) adds that the technical scheme of 80% crop straws for producing particieboard reports, it is open that also useful urban waste wood materials is produced the technical scheme of particieboard, but also do not utilize cornstalk, wheat straw to mix saw wood ash, wood fragments slag to do the technical scheme of particieboard simultaneously.Summary of the invention
The object of the present invention is to provide a kind of particieboard and production method thereof that multiple discarded object is produced that fully utilize.
The component that product of the present invention contains following weight ratio: saw wood ash 29～31%, wheat straw 19～21%, cornstalk 29～31%, wood fragments slag 19～21%.
The production method of product of the present invention is for carrying out according to the following steps:
1,, by wooden slag, wheat straw, cornstalk are pulverized;
2, by weight by the broken wheat straw 19～21% of upper step gained, broken cornstalk 29～31%, wood fragments slag 19～21%, and the saw wood ash 29～31% of collecting is allocated mixing;
3, glue mixing;
4, mat formation;
5, hot pressing;
6, saw limit;
7, sanding.
The glue kind of producing particieboard is many, generally taking phenol glue (PF), urea-formaldehyde glue (UF) melamine modified urea-formaldehyde glue (MUF), isocyanate glue (MDI) as main.PF glue color is brownish red, so the product colour of producing is partially dark.This glue kind is more crisp after solidifying, and the product processing characteristics of production is not as other glue kinds.MUF glue color is creamy white, so the production board face of producing is subject to the impact of glue color hardly, after glue solidifies, pliability is better, and the nail-holding ability of sheet material is good, and be easy to processing and be easy to engraving, but water boiling resistance not.MDI glue is colourless without aldehyde; be the glue kind of at present tool environmental-protecting performance, resin added is low, every cubic metre of sheet material applying glue 9-24 kilogram; sheet material color is good; physicochemical property excellence, but need in process of production releasing agent, the adhering to of glue, the paint the etc. when releasing agent of plate surface affects secondary operations; situation needs sanding processing mostly; if but the direct exposed use of plank, the releasing agent on plank surface will play fabulous protective effect to plank, and plank surface smoothness is also fine simultaneously.
Beneficial effect of the present invention: can fully utilize multiple discarded object and produce qualified particieboard, can protection of the environment, reduce municipal refuse, protect forest resources.
Detailed description of the invention
Embodiment:
Discarded construction site, local city wooden unit, stub bar and furniture factory's leftover pieces are sent into hammer crushing after the deironing of permanent magnetism deironing roller and be machined to wood fragments, wood fragments are placed on belt conveyer and carry, on belt conveyer, there is permanent-magnet iron removing device, wood fragments are again by sending into impurity such as shedding seperator separating paper, plastics and nonferrous metal after permanent magnetism deironing roller gap iron, wood fragments after separation sift out impurity by oscillating riddle, obtain one of particieboard raw material wood fragments slag.
By wheat straw, the cornstalk short material of mm that degree of being cut into is 12mm～25 respectively, send into respectively cylindrical drier dry, dry rear short material enters vibratory sieve, crosses the sieve aperture of 8mm × 12mm, obtains respectively the broken wheat straw of particieboard raw material and broken cornstalk.
By weight by the broken wheat straw 20% of upper step gained, broken cornstalk 30%, wood fragments slag 20%, and the saw wood ash of collecting 30% is allocated mixing.Adopt spiral sizing applicator glue mixing, according to the ratio glue mixing of siccative and hard resin 100:4, separately add paraffin water repellent and the weak acid curing agent of usual amounts, controlling aridity is 2 hours.
Raw material after glue is mixed is delivered to spreading machine, mat formation and to have the smooth continuous bulk slab of grading structure by spreading machine, make again the slab with some strength of bonding through preformer, edging saw, briar, send in loader through plate blank conveyer, ledal-pushing machine, by loader, slab is sent into together in hot press and is pressed into particieboard, the burr plate of hot pressing in hot press is released in unloader by the backing plate of loader simultaneously.Hot-forming rear saw limit, sanding obtain product.
70 yuan of every retail prices of particieboard of specification 2.44 × 1.22 × 0.015.
The economic effect of the present embodiment project:
(1) meet national industry development policies, meet national economic development and strategic directing thought and deployment.
(2) to architectural engineering scoot, saw wood ash, and the recovery of agriculture wheat straw, cornstalk processing, can develop waste resource, brought into play again protection of the environment, and the effect of municipal refuse is conducive to promote to protect forest resources.
(3) for the unemployment resident of community has set up the workbench of a reemployment.
(4) financial analysis shows, project can obtain good economic benefit, is conducive to the development of local economy and the growth of the income of residents.
