Abstract
The invention discloses a method of producing medium density fiberboards by the use of waste materials. The method produces medium density fiberboards by the use of waste timbers in Sinkiang as raw materials. Slabs (wasted scraps produced after manufactures with saws in Sinkiang use log saws for sawing plates), woods dying a nature death and dying in nature disasters, and tree branches are intensively transported for full comprehensive utilization, which takes the lead in the production of medium density fiberboards by waster materials. The produced medium density fiberboards have excellent quality with light pine fragrance, not only greatly increases the internal bonding strength, bending strength, elastic modulus and waterproof performance, but also saves plenty of natural resources for nation and simultaneously solves the practical issue of local harsh employment.
Description
Technical field
The present invention relates to a kind of method of utilizing waste material to produce medium density fibre board (MDF).
Background technology
Density board also claims fiberboard, is take wood fibre or other plant fiber as raw material, applies the artificial board that Lauxite or other applicable adhesive are made.By the difference of its density, be divided into high-density plate, medium-density plate and low-density plank.
Density board is because matter is soft shock-resistant, and also easily reprocessing, is a kind of good material of making family property abroad, but due to country about the standard of high-density plate than the low several times of international standard, so density board need to improve in the service property (quality) of China.
MDF is medium density fibre board (MDF), it is the one of density board, it is take wood fibre or other plant fiber as raw material, through smashing, fiber separation, dry after-applied Lauxite or other applicable adhesive, a kind of artificial board of making after hot pressing again, its density is generally at 0.5-0.8 gram per centimeter
3scope, thickness is generally 3-30 millimeter.
Because MDF fibr tissue is even, interfibrous bonding strength is high, therefore its MOR, plane tensile strength, modulus of elasticity are good.But a little less than holding screw power geometric ratio particieboard, wear into fiber because MDF is log, changed the structure of timber completely.And moisture absorption, water absorbing properties, thickness swelling are higher.
Due to medium density fibre board (MDF) surfacing, smooth, be convenient to the finishing materials such as gluing plane veneer processed and tissue paper, and be convenient to cover with paint, lacquer, colour wash, etc. and saving color.
Medium density fibre board (MDF) can be produced from several millimeters to tens millimeters thick sheet materials, can replace plank, the square bar of any thickness, and there is good machining property, sawing, boring, fluting, mortise, sanding processing and engraving, the edge of plate can be by any shape processing, and processing rear surface is smooth.
Due to medium density fibre board (MDF) function admirable, and be timber comprehensive utilization, the reasonable effective way of utilizing, therefore, medium density fibre board (MDF) is one of at present the most rising product.
The feature of medium density fibre board (MDF) is:
1. internal structure is even, and density is moderate, good stability of the dimension, and deflection is little, and physical and mechanical property is moderate.
2. surfacing is smooth, and machinability is good, can paste the veneer of slicing or decorative pattern novelty, beauty thereon, thereby be loved by the people in home decoration, is usually used in making furniture, dividing plate etc.
The item of selecting medium density fibre board (MDF) to note has:
1. whether outer its thickness, density watched is even, and corner has and there is no breakage, whether has the phenomenons such as layering, bulge, carbonization, has or not soft part.
2. while having ready conditions, can sawing a fritter medium density fibre board (MDF), to be placed on water temperature be to soak 24 hours in the water of 20 ℃, sees its varied in thickness, and access panel face has and there is no little bulge simultaneously.Varied in thickness is large, and plate face has little bulge, illustrates that plate face water proofing property is poor.
3. the low medium density fibre board (MDF) of selective liberation amount, hears with sense of smell when selection, should select the medium density fibre board (MDF) that pungent taste is little, because smell is larger, illustrates that burst size of methanal is just higher, and the pollution causing is also just larger.
Nearly 9000 ten thousand steres of China's wood-based plate output in 2008, wherein fiberboard output is 2800 ten thousand steres, all rank first in the world, and the high yield of wood-based plate support downstream, China has formed furniture and the floor export sector of global maximum.
Since the nineties in 20th century, industry of artificial boards obtains flourish at home, but is distributed in the ground such as Guangxi, Fujian, Shandong, Jiangsu more, and take small enterprise as main.Take Pizhou City of Along North Jiangsu as example, it has artificial board enterprise family more than 3000 at present, and 4800 of Linyi, Shandong total all kinds of sheet material manufacturing and processing enterprises.
The professor Shen Shijie of Beijing Forestry University analyzes, recent year artificial board enterprise is flourish, but scale is still less than normal, and few, with low content of technology, the ropy problem of ubiquity investment in research and development, cause waste low-grade wood-based panel product large, that pollution is heavy to flood the market, upset the normal order in market and fair competition.
