Bamboo, fibre-bearing and plastics papermaking solid waste wood-based plate and its manufacturing process
Technical field
The present invention relates to wood-based plate manufactures manufacture field, more particularly, to a kind of bamboo, fibre-bearing and plastics papermaking waste people
Make plate and its manufacturing process.
Background technology
The Eleventh Five-Year Plan period, China's Mainland adds up to produce wood-based plate 52585 ten thousand stere, and wherein plywood 214,220,000 stands
Square rice, fibre board 15946 ten thousand stere, particieboard 5510 ten thousand stere, other wood-based plate 9707 ten thousand steres.2010, in
State's wood-based plate yield 15361 ten thousand stere, creates the highest record in history.Wherein, plywood 7140 ten thousand stere, increases by a year-on-year basis
60.4%;Fibre board 4355 ten thousand stere, increases by 24.8% on a year-on-year basis;Particieboard 1264 ten thousand stere, reduces 11.7% on year-on-year basis;Its
He increases by 19.6% on a year-on-year basis by wood-based plate 2602 ten thousand stere (core-board accounts for 63.5%);The same year also produces 27,240,000 cubes of veneer
Rice, 2.9 hundred million square metres of wood-based plate surface decorating plate.
It is subject to global concern in current climate change, conserve forests and become human consensus, and forest reserves day can be adopted by the world
In the case that benefit reduces, socio-economic development is continuously increased to timber and its product demand, make full use of artificial fast-growing Commercial Forests,
Forest Cultivation and logging residue and production and construction, renovate during the resource development wood-based plate such as discarded wood fibre,
To substitute traditional timber product, to protection wildwood resource, improve the ecological environment, meet economic construction and social development pair simultaneously
The demand of forestry products, has the ability of irreplaceable effect and long-term sustainable development.China's bamboo timber resource enriches, and its yield occupies
First place in the world.In China, particularly south China, bamboo wood fast growth, growth just can utilize for 1 year, and bamboo wood specification is relatively
Little, fell performance good.Bamboo product and woodwork have similar benefits simultaneously, and bamboo flooring bar and wood lath all have moistureproof, heat-insulated, guarantor
Warm, wear-resisting, anti-skidding, to electric insulation, easy cleaning, there is higher intensity etc..
In paper-making process in addition to meeting produces substantial amounts of waste water, also substantial amounts of solid waste produces.With industry rule
The gradually expansion of mould, the environmental effect that these solid waste are brought also becomes increasingly conspicuous, the various ecological problem of the thing followed and society
Problem also can gradually highlight, become one of emphasis and difficult point of industrial pollution caused by paper manufacturing improvement;Fibre-bearing and the papermaking of plastics
Solid waste is mainly derived from timber and the material papering section of non-plant fibre raw pulp process and regenerated papermaking screens and floating
During choosing, its yield is considerable.At present, these solid waste generally to be processed using the method burned or fill.
Although burning method make use of the heat energy of these papermaking solid waste, it is a kind of utilization approaches, in burning process, also can release
Release various harmful gass, environment can be affected, the ashes simultaneously dealing carefully with these garbages are also required to throw
Enter certain manpower financial capacity, its comprehensive effect is not ideal enough compared with recycling these solid waste.Using landfill
Mode not only can take land resource valuable in a large number, and it has secondary pollution to ocean water quality, soil and subsoil water etc. simultaneously
Potential hazard.
Papermaking solid waste using resourceful bamboo timber resource and fibre-bearing and plastics prepares wood-based plate, no matter
Still it is respectively provided with good meaning from the sustainable development of resource for the recycling angle of resource.
Content of the invention
It is an object of the invention to provide a kind of bamboo, fibre-bearing and plastics papermaking solid waste wood-based plate and its manufacturing process
Employed technical scheme comprise that for achieving the above object:
A kind of bamboo, fibre-bearing and plastics papermaking solid waste wood-based plate, solid with fibre-bearing and plastics papermaking using bamboo
Body garbage through hot-press gluing molding, raw material weight proportioning of soup processed is
Bamboo:Fibre-bearing and plastics papermaking solid waste ratio are:1: 0.5~1;
And add above-mentioned gross weight 10%~20% adhering resin.
Further, described bamboo can be formed through rolling to crush by raw bamboo, or raw bamboo section forms, or adopts bamboo wood
Leftover pieces in processing, or the mixture of three.
Further, described fibre-bearing and plastics papermaking solid waste are wood flour or the system of getting the raw materials ready in wood pulping process
The screenings of slurry process, or wheat bran, wheat slag or reed that non-wood pulping process produces are last, or process is produced by regenerated papermaking system
Light plastic, or multiple mixture above.
Further, described adhering resin is phenolic resin, Lauxite or melamine resin.
The manufacturing process of bamboo, fibre-bearing and plastics papermaking solid waste wood-based plate, comprises the steps of:
(1) selection, dispensing
Bamboo:Fibre-bearing and plastic solidification garbage ratio are:1: 0.5~1;
(2) it is dried
Raw material is carried out to compound using rotary drier and is dried process
Baking temperature:60~80 DEG C, after the completion of being dried, mixture moisture is less than 6%;
(3) mix
Mixed processing is carried out to compound using high-speed mixer
Mixing velocity:1500~2000r/min, incorporation time 20~30min;
(4) add adhering resin
Add said mixture ratio for 10%~20% adhering resin;
(5) base, hot pressing
Carry out hot pressing using after blanking device base, delivering to hot press
Hot pressing condition:170 ± 5 DEG C, pressure 1.0~3.5MPa, time 3~10min;
(6) cold pressing sizing
The blank cold press completing hot pressing is carried out sizing of colding pressing
Cold pressing condition:Pressure 1.0~1.5MPa, 10~20 DEG C of temperature, time 3~8min;
(7) standing is deposited
Storage environment temperature:25~30 DEG C, humidity RH is less than 50%, and the resting period is no less than 48h;
(8) cut.
The present invention has advantages below:
1) present invention adopts resourceful bamboo wood as one of raw material, can replace timber and be used for manufacturing wood-based plate, energy
Enough it is effectively protected the forest reserves, reduce transition and fall trees;
2) make full use of the papermaking solid waste of fibre-bearing and plastics, process phase with using burn processing or burial
Equipment investment is low, will not produce toxic and harmful, to environmental pollution, will not be simultaneously achieved the high level of garbage for ratio
Change and utilize, the solution of the pollution problem of papermaking enterprise solid waste can be replaced to provide a feasible method;
3) adopt bamboo and fibre-bearing and plastics papermaking solid waste as raw material of artifical plate, cost of material is relatively low
Honest and clean, therefore, it is possible to effective production cost reducing sheet material;
4) fiber in bamboo and fibrous papermaking solid waste be in hot pressing, bamboo fibre and solid waste
In fiber in the presence of adhering resin mutually overlap joint formed with entirety, be conducive to the raising of wood-based plate intensity;Bamboo and with
During plastic components hot pressing in solid waste, plastic components melt, and be interconnected to form one, improve plate and bamboo between
The density of material, simultaneously as the hydrophobicity of plastics itself, can reduce the water absorption rate of wood-based plate, thus it is swollen to reduce water sucting thickness
Swollen rate;
5) fibre-bearing producing during making full use of paper-making pulping and plastic solidification garbage, are former completely with garbage
Material replaces the formaldehydeless building board waiting additive of original production raw material next life product, can be with effectively solving papermaking solid waste
Pollution problem, saves primary timber and plastics, is of great immediate significance with preserving the ecological environment to saving natural resourcess.
