Description
Technical field
It is especially a kind of with the papermaking process that bagasse is raw material the present invention relates to a kind of method of papermaking.
Background technology
China is a papermaking big country and possesses long history.Paper making raw material mainly based on timber, careless class, bamboo wood,
Its paper technology slightly has difference because raw material is different, and the basic technology using timber papermaking is：Cut-out → boiling → bleaching → mashing
→ copy paper, its shortcoming are：The technological process is although feasible, but as a result of digesting technoloy, energy consumption is higher, and pollution is very big；
During bleaching, using caustic soda, hydrogen peroxide, urea etc., and environment is unavoidably polluted.
At present, the tropical plants in tropical and subtropical region are more, south China category subtropical zone, it is sweet to adapt to plantation
Sugarcane, sugarcane are a kind of annual or perennial root Perenniporia martius herbaceous plant, belong to C4 crops.Sugarcane stem is upright, sturdy
White powder is often draped over one's shoulders on succulence, surface.Leaf is alternate, and edge has small sharp mouth shape, and flower spike is compound raceme.Sugarcane makees for happiness temperature, light
Thing, annual accumution need to be 5500 DEG C~8500 DEG C, more than frost-free period 330d, average annual air humidity 60%, and annual precipitation requirement 800~
1200mm, sunshine time is more than 1195 hours.Sugarcane to the adaptability of soil than wide, with clay loam, loam, sandy loam
Preferably.4.5~8.0, sugarcane can grow soil pH value, but be suitable with soil pH value 6.5~7.5.
Sugarcane is one of primary raw material of sugaring.The remaining bagasse after squeezing sugar, there are about 50% fiber can use
Carry out papermaking.But, wherein still there is part sugarcane marrow（Myelocyte）Do not interweave power, should be removed before pulping process.Bagasse fibre
Length is about 0.65-2.17mm, and width is 21-28 μm.Although its fibre morphology is less than timber and bamboo, than rice,
Wheat straw fiber is then slightly better.After slurry can be incorporated part wood pulp, offset printing paper processed, cement bag paper etc. are copied.
In recent years, although someone has invented the method with bagasse extraction fiber, the fiber content extracted is only original
20%~40% come, still has many chopped fibers to follow waste material to discharge together during fiber is extracted, therefore after extracting fiber,
The stacking of left waste material causes secondary environmental pollution again.Bagasse is difficult to collect and stored, reason be its chemical composition and
Physical characteristic, cannot be with the basic technology of timber papermaking come papermaking if the production technology of papermaking is immature.
The content of the invention
It is an object of the present invention to provide a kind of development cost is relatively low, to have broken traditional paper technology, labor intensity less
With the papermaking process that bagasse is raw material.Not only turn waste into wealth, make full use of resource, new former material is provided for China's paper industry
Expect resource；Required equipment is simple, and general enterprises staff is also easily mastered；Without the addition times during slurrying, grinding
What chemical assistant；To reducing because papermaking needs cut down forest, protecting ecology plays positive role.
It is above-mentioned technical problem to solve, the technical scheme is that：
It is this with the papermaking process that bagasse is raw material, the raw material of papermaking are used as by the use of bagasse；It comprises the following steps：Material
The collection of material and edge damage；Cut up with a hay cutter broken；Thread rolling；Pulp washing；Grinding；Into slurry；Dispensing；Mashing off；Copy paper；The collection of the material and edge damage are
Refer to：By sugarcane concentrates storage, manually or mechanically edge damage is standby；Cut up with a hay cutter broken refer to：Using common hay cutter by material hand hay cutter be broken into it is small
Block piece；Thread rolling refers to：It is fed directly into spiral thread rolling machine and carries out thread rolling grinding, its fiber and marrow is decomposed；Pulp washing refers to：By washing
Slurry removes marrow；Grinding refers to：Dope presses fiberizer grinding into screened stock during fiber is put into；Refer into slurry：Measure bagasse pulp
PH value be 3~5, Baume degrees be 23 degree；Dispensing refers to：Above-mentioned slurry and modified tapioca starch are pressed into 1000: 1 weight proportions, added
Enter modified tapioca starch；Mashing off refers to：The mixture of bagasse pulp and modified tapioca starch is heated into boiling to 100 degree；Copy paper
Refer to：Upper paper machine produces brown paper.
When cutting up with a hay cutter broken, material hand hay cutter can be broken into 15 × 10cm small block piece by common hay cutter.
Beneficial effects of the present invention：
The invention is that a kind of development cost is relatively low, convenient and practical, labor intensity is less with the papermaking process that bagasse is raw material.
Not only turn waste into wealth, make full use of resource, new raw material resources is provided for China's paper industry；Required equipment is simple, and one
As enterprise work personnel be also easily mastered；Without adding any chemical assistant during slurrying, grinding；To reducing because papermaking needs
Cut down forest, protecting ecology plays positive role；Traditional paper technology is broken, bagasse is fully utilized；
It is a kind of paper technology of pure natural nothing " three wastes " discharge.
It is raw material come the technical barrier of papermaking that the present invention, which is solved with bagasse, have found wide to go out for its application
Road, make growth of agricultural efficiency, increasing peasant income, in the production method of the papermaking, eliminate traditional boiling, bleaching process, drop significantly
Low industrial pollution, the cost of papermaking is greatly reduced, improve the economic benefit of enterprise, meanwhile, substantial amounts of timber can be saved
Resource, there are good ecological benefits and social benefit.
