Description
Technical field
The present invention relates to waste paper ink and gluing thing processing technology field, particularly relate to a kind of wastepaper ink and synchronously process biology enzyme composition and the application thereof of gluing thing.
Background technology
In today that every cost is surging, energy-saving and cost-reducing meaning is concerning day by day far-reaching paper industry, improve waste paper recycling rate and then solve this difficult problem well, but the impurity of various complicated component, wide variety is entrained in waste paper and enters the paper machine circulatory system, series of problems is brought to waste paper recycling process, wherein, the impact especially brought with ink and gluing thing is the most outstanding.And increasing of gluing thing, papermaking wire-cloth, woollen blanket, drying cylinder, felt wrapped roll can be polluted, also can cause paper defects, disconnected paper simultaneously, finally also can affect following process and presswork.
The kind of gluing thing is many, and is differed greatly by the difference of paper kind, and the waste paper kind that wastepaper comprises is very wide, containing electro-photographic paper, laser printing waste paper, computer printout waste paper, account book waste paper, publication waste paper, heat-sensitive paper, impact paper and cardboard etc.Due to office automation in recent years and informationalizedly to develop rapidly, the amount of office waste grows with each passing day.Gluing owner in wastepaper will from the adhesive tape in waste paper, label, hot melt adhesive residue, coating, wax, ink bridging agent, latex, wet strength agent and other polymer, also have residual ink and the inorganic constituents of large percentage in addition, they do not have viscosity, but quite a few has lipophilicity, easily adhered to by stickum and deposit.In the past, deinking and the process of gluing thing can utilize chemical method process respectively and obtain good effect, but chemical deinking and removal gluing thing all can cause larger environmental pollution.Along with the development of biotechnology, the biology enzyme that environmental pollution is very little is applied in the middle of deinking and stickies removal, correlation technique, and especially enzymatic deinking technology reaches its maturity.Adopting biology enzyme to carry out to secondary stock, people in the process of deinking pay close attention to is its deinking efficiency, and have ignored gluing thing process problem.Similarly, people also have ignored deinking process problem while to the process of gluing thing, thus make people deinking process and the process of gluing thing be regarded as two processes of being not too correlated with, by deinking and stickies removal separately process.Along with people are to after the research of the formation of gluing thing more and more deeply, it is found that during secondary stock is recycled that the gluing thing produced is except the salt of adhesive, sizing agent, hot melt material, wax, natural resin and formation thereof, very major part is the ink, deinking agent composition (such as defoamer) and the inorganic constituents that produce in deinking process, therefore, it is absolutely not two processes of being not too correlated with that enzymatic deinking and biology enzyme remove gluing thing, must continue further investigation to deinking technology and stickies removal problem.When current wastepaper as raw material quality constantly worsens, still deinking and gluing thing process two problems are separately carried out studying the needs that can not meet production practices, only have and deinking and the process of gluing thing are integrated, just can have the comprehensive removal effect of impurity, just have more realistic meaning.
Existing deinking process and stickies removal process are isolated, and this not only causes the waste of resource, and treatment effeciency is low.Therefore, deinking and sicker should be removed problem and synchronously process, namely consider the correlation between deinking and stickies removal, deinking is processed together with stickies removal.But also do not use biology enzyme composition to carry out the report of synchronous process to wastepaper ink and gluing thing at present.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of wastepaper ink and synchronously process biology enzyme composition and the application thereof of gluing thing, described biology enzyme composition is at suitable temperature and pH, by biology enzyme various in biology enzyme composition, synergy between auxiliary agent, deinking office waste paper and stickies removal are synchronously processed, simplify paper technology step, treatment effeciency is high, flotation whiteness improvement value average out to 3.6%ISO, flotation residual ink clearance average out to 71.3%, flotation large stickies removal rate average out to 74.2%, flotation microstickies clearance average out to 63.3%, deinking efficiency and stickies removal effective, and can pulp quality be improved, promote the paper machine life-span.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of wastepaper ink and gluing thing synchronously process biology enzyme composition, percentage, described biology enzyme composition is composed of the following components:
Wherein, described surfactant is one or both in fatty alcohol-polyoxyethylene ether and OPEO, and the carbon number of described Organic Alcohol is 2 ~ 4.
In one embodiment of the present of invention, described Organic Alcohol is made up of ethylene glycol 15%, BDO 15% and diethylene glycol (DEG) 12%.
In an alternative embodiment of the invention, described Organic Alcohol is made up of ethylene glycol 15%, BDO 15% and diethylene glycol (DEG) 8%.
Preferably, described diastatic enzyme is lived as 4000U/g, and the enzyme of described laccase is lived as 10000U/g, the enzyme of described cellulase is lived as 2000U/g, the enzyme of described pectase is lived as 5000U/g, and the enzyme of described zytase is lived as 50000U/g, and the enzyme of described lipase is lived as 10000U/g.
For solving the problems of the technologies described above, another technical solution used in the present invention is: provide the application of described biology enzyme composition in wastepaper ink and gluing thing synchronously process, and the addition of described biology enzyme composition is 0.08% ~ 0.12% of described wastepaper weight.
Preferably, the addition of described biology enzyme composition is 0.1% of described wastepaper weight.
Preferably, the temperature that described wastepaper ink and gluing thing synchronously process is 45 DEG C ~ 55 DEG C.
Most preferably, the temperature that described wastepaper ink and gluing thing synchronously process is 50 DEG C.
Preferably, the pH value that described wastepaper ink and gluing thing synchronously process is 6.0 ~ 8.0.
Most preferably, the pH value that described wastepaper ink and gluing thing synchronously process is 8.0.
Because most gluing thing all contains a large amount of ester bonds, the component of gluing thing can be connected by these ester bonds, laccase can make these ester bonds rupture, impel its component to reduce viscosity, thus decrease the harm of gluing thing, in addition, laccase is by the lignin in catalysis fibre, generate benzene oxygen radical, further Raolical polymerizable occurs, improve pulp strength.
The invention has the beneficial effects as follows: distinguish existing biology enzyme deinking process and stickies removal process is isolated, cause the wasting of resources and the low situation for the treatment of effeciency, wastepaper ink of the present invention and gluing thing synchronously process uses biology enzyme composition, at suitable temperature and pH, by biology enzyme various in biology enzyme composition, synergy between auxiliary agent, the gluing thing in slurry is removed while deinking is carried out to wastepaper, namely deinking office waste paper and stickies removal are synchronously processed, simplify paper technology step, treatment effeciency is high, flotation whiteness improvement value average out to 3.6%ISO, flotation residual ink clearance average out to 71.3%, flotation large stickies removal rate average out to 74.2%, flotation microstickies clearance average out to 63.3%, deinking efficiency and stickies removal effective, and can pulp quality be improved, promote the paper machine life-span.
