Description
Technical field
The present invention relates to a kind of preparation method and applications of paper grade (stock) recycled fiber modified enzyme, belong to paper technology neck
Domain.
Background technology
China paper industry especially wrapping paper, maintains the situation to grow continuously and fast in recent years.And Chinese papermaking is fine
Tie up that resource is relative to be lacked, supply capacity can not meet that production capacity expands needs, and Chinese paper making raw material category is stood like the legs of a tripod situation.In
Papermaking association of state calculates, and wood pulp usage amount proportion accounts for the 23% of raw material total amount at present, and non-wood pulp proportion accounts for 15%, secondary stock proportion
62% is accounted for, waste paper has turned into the most important dependence resource of China paper industry development, and wrapping paper paper kind secondary stock ratio is even more height
Up to more than 80%.But with the increase of secondary stock ratio, recycled fiber, recycled fiber more and more using number in waste paper
Damaged in recycling increasingly severe, quality worse and worse, turns into and restricts waste paper and recycle the life of wrapping paper business stability
Production and the bottleneck of stabilised quality.
The content of the invention
It is an object of the invention to provide a kind of preparation method of paper grade (stock) recycled fiber modified enzyme, its technique is simple, into
This is low；Simultaneously the invention provides a kind of simple application process, the quality of reclaimed fibre is which improved, improves paper matter
Amount, reduces wet end chemistry product dosage, reduces the COD contents of waste discharge.
The preparation method of paper grade (stock) recycled fiber modified enzyme of the present invention, comprises the following steps：
(1) recycled fiber is mixed to simultaneously feeding poultry with feed, then collects poultry manure；
(2) fibrous raw material in excrement is cleaned and analyzed, filter out fibre strength lifting 15-20% excrement；
(3) enzyme in excrement obtained by step (2) is exported with starch fluid, then with certain temperature, pH value, oxygen
Enzyme is cultivated in the starch of concentration, gamma-rays and mass concentration；
(4) enzyme of culture in step (3) is screened, produces paper grade (stock) recycled fiber modified enzyme.
In step (1), recycled fiber is dissolved into the suspension that mass concentration is 4-5% with clear water, it is then dense with quality
The corn feed for 15-16% is spent by 1:5~7 over dry ratio mixing.
In step (3), the mass concentration of starch fluid used is 12-14%.Required temperature is 37-43 DEG C during culture, pH value
For 6.5-8.0, oxygen quality concentration is 14-16%, and gamma intensity 0.6-0.8mci, the mass concentration of starch is 12-
14%.
Export is a kind of method for guiding mushroom to the high solution motion of nutrient according to biology and collecting.When exporting enzyme, root
According to the habit of enzyme, to starch concentration high solution direction life movement can occur for enzyme.
In step (4), by limiting above-mentioned condition of culture, the bacterium colony color of strain, enzyme are observed to pH susceptibility, aerobic
Degree, a small amount of described modified enzyme is added in the waste paper pulp of multiple reuse and reacted, filter out gained paper
Ring crush intensity, which can increase 10-15%, folding strength and can improve 15-20%, bursting strength, can improve 10-12% paper grade (stock) recycled fiber
Modified enzyme.
The application of described paper grade (stock) recycled fiber modified enzyme, be by paper grade (stock) recycled fiber modified enzyme expand culture after,
It is 37-43 DEG C, pH value 6.5-8.0 i.e. in temperature, oxygen quality concentration is 14-16%, gamma intensity 0.6-0.8mci,
The mass concentration of starch is that 12-14% conditions are continuously cultivated, and controls above-mentioned concentration and conditional stability, increase by 75% in every 48 hours
Volume, cultivate to 200 kilograms, be added in the waste paper pulp of multiple reuse and reacted, then gained slurry is made
Paper carry out performance detection.Addition is that 100-120g paper grade (stock) recycled fiber modified enzymes are added in bone dry fiber per ton.
The temperature of waste paper pulp is 35-55 DEG C, pH value 6-8.5, reaction time 0.5-1h during the reaction.
By edible decomposition of the poultry to wastepaper as raw material, filter out suitable enzyme in excrement, then by biology enzyme with
The reactions such as starch, soluble gums, fiber fines (below 120 microns of diameter) in multiple reclaimed fibre, generate low molecule amount
Carbohydrate, repair, improve the unfavorable factors such as damage of the multiple reclaimed fibre in multiple reuse, addition, so as to reach
Having arrived improves fiber quality, improves the effect into paper physical index, reduction pulp-making waste-water COD contents, reduce further enterprise
Handle the load of waste paper.
The present invention compared with prior art, has the advantages that：
(1) preparation method of the paper grade (stock) recycled fiber modified enzyme described in, its technique is simple, cost is low；
(2) application process of the paper grade (stock) recycled fiber modified enzyme described in, it is simple and practical, improve the matter of reclaimed fibre
Amount, improves paper quality, reduces wet end chemistry product dosage, reduce the COD contents of waste discharge.
(3) relative to be not added with for the paper of paper grade (stock) recycled fiber modified enzyme, the ring crush intensity of gained paper adds
10-15%, folding strength improve 15-20%, and bursting strength improves 10-12%；The discharge waste water COD of slurrying simultaneously declines 20-25%.
