Abstract
An artificial board is made up of the mud-state waste of paper mill and the fibrous material as auxiliaries through hot pressing. Its advantages include low cost, environment protection and wide application.
Description
The present invention relates to a kind of production of hot-pressed board, refer to that especially a kind of discarded object with the paper mill is the sheet material that base-material is produced.
As everyone knows, present wood-based plate majority is a raw material with born log, three-ply board for example, particieboard, fiberboard etc., and along with rapid development of national economy, society is to timber, the demand of sheet material is also increasing, and the China and the extremely global forest reserves extremely lack particularly overcut, severe water and soil erosion, cause serious disparities between supply and demand, and with the fiber material in process of production, producing large quantities of stasis of blood mud shape short fiber discarded objects as the paper mill of raw material, this discarded object is too short because of fiber, impurity content is many and can't enter production field again, and environment is had serious pollution, and factory generally all is can only be by burning and the means of landfill are handled, and pollutes but still atmosphere and underground water produced, all multifactor, make the development of factory be subjected to great limitation.
The objective of the invention is to utilize the discarded object in paper mill to produce artificial board.
The present invention is achieved through the following technical solutions: with the paper mill discarded object is base-material, and all the other are aided with the fiber material is the material that auxiliary material is mixed with the hot pressing wood-based plate.
1) → stone → hot-forming its production technology is: anhydrate oven dry (anhydrate＞90%) → base-material, auxiliary material pulverizing → base-material and auxiliary material of base-material, auxiliary material mixes → glue mixing (material and glue ratio 4-7: by a certain percentage in the requirement of strength of sheet material.
The present invention has following advantage owing to adopt the base-material of the discarded object in paper mill as wood-based plate.
1, low price because of substituting born former material with discarded object, greatly reduce production cost, and performance is also approaching with the MDF of equal performance;
2, of many uses, can make noble furniture, wood block floor, packing case, audio amplifier etc.;
3, become useless and be useful material, both reduced environmental pollution, make Wood-based Panel Production factory open up new base material raw material sources again, environmental protection and ecology are played a very good protection.
The invention is characterized in: the stasis of blood mud shape discarded object (being commonly called as 4-5 level waste material) with the paper mill is a base-material, and all the other are aided with the fiber material is auxiliary material (as straw, bagasse, straw, mao bamboon etc.), is mixed with the material of hot pressing wood-based plate.
Its production technology:
The 1st step: base-material, the auxiliary material oven dry (anhydrate＞90%) of anhydrating;
The 2nd step: base-material, auxiliary material are pulverized;
The 3rd step: base-material and auxiliary material mix by a certain percentage by the requirement of strength of sheet material;
The 4th step: → glue mixing (material and glue ratio 4-7: 1);
The 5th step: stone;
The 6th step: hot-forming.
Described base-material shared ratio≤60% in material.
The present invention is further described according to embodiment below:
Embodiment A: make hardboard
A, raw material: the paper mill waste material accounts for 40%, 4 grade for 5 grades and accounts for 20%, and sawdust (wooden chaff) accounts for 20%, and wood shavings account for 20%
B, with above-mentioned drying materials (anhydrate＞90%)
C, material mix (5-6) with glue (pollopas): 1
Carry out hot pressing behind d, the stone,
Temperature: 180 ℃, pressure 30Mpa, time 〉=6 minute
Finished product density, 0.83-0.88.
Embodiment B, medium density fibre board (MDF)
A, raw material: 5 grades in paper mill waste material accounts for 40%, 1 grade and accounts for 20%, 2 grade and account for 20% sawdust (wooden chaff) 20%;
B, with above-mentioned drying materials (〉=90%)
C, material mix (45-6) with glue (pollopas): 1
Carry out hot pressing behind d, the stone
Temperature: 180 ℃, pressure 28MPa, time 〉=5 minute
Finished product density 0.75-0.8
The present invention is owing to adopt the discarded object, the particularly discarded object of stasis of blood mud shape in paper mill, and promptly environmental pollution has severe contamination and must burn or the pollutant of landfill.Discarded object after treatment becomes the required sheet material that helps human being's production and life, has both opened up the market, material source of artificial board, has removed pollutant again in a large number, and great function has been played in the protection of environment.
