Abstract
The invention discloses a production method of renewable environment-friendly thermosensitive base paper. The production method comprises the steps of size degradation, impurity removal and separation, bleaching and proportioning, meshing and forming, squeezing and dehydration, drying, surface sizing, drying and calendering, reeling and slitting, and packaging finished products, wherein in the size degradation process, 100% of office waste paper raw materials are adopted for size degradation, and the size degradation concentration is controlled to be 5%-6%. According to the production method, office waste paper pulp is adopted for replacing bleached chemical pulp, so that the fiber recycling is increased, the economic benefits of enterprises are increased, meanwhile, the production cost of the thermosensitive base paper is significantly reduced, the environmental pollution is also reduced, and the investment of the enterprises in the waste water recovery process is reduced; in addition, the quality of products produced by the method is good, and the production method can be applied to the production of thermosensitive paper.
Description
Technical field
The present invention relates to the production method of temperature-sensitive body paper, relate in particular to a kind of production method of regenerative environment-friendly temperature-sensitive body paper.
Background technology
The temperature-sensitive body paper is for being coated with the paper of thermo colour, and along with economic develop rapidly, the utilization of temperature-sensitive body paper in being expert at is more and more general, in prior art, is all to adopt traditional bleach chemical pulp production temperature-sensitive body paper.Bleach chemical pulp is to remove most of non-cellulose composition by chemical method and the paper pulp that makes from plant fiber material, contain a large amount of chemicals in this kind of bleach chemical pulp, can produce a large amount of pollutant effluents in the production process of body paper, give great pressure to environment, and also increased sizable pressure in the waste water removal process enterprise, entreprise cost is invisible to be increased.
Therefore, be badly in need of to find the production method of the good temperature-sensitive body paper of a kind of environmental protection, low production cost, product quality.
Summary of the invention
The object of the invention is to propose a kind of production method of regenerative environment-friendly temperature-sensitive body paper, the product quality that this kind of production method environmental protection, low production cost, production obtain is good.
In order to solve the prior art problem, the present invention is achieved by the following technical solutions.
A kind of production method of regenerative environment-friendly temperature-sensitive body paper, its step comprises: size degradation, removal of impurities separate, bleaching with slurry, upper net forming, press dewatering, drying, top sizing, oven dry press polish, batch cut, the packed products operation, wherein, in the size degradation operation, adopt 100% wastepaper raw material to carry out size degradation, beating degree is controlled at 28 ~ 36 ° of SR, and size degradation concentration is controlled at 5-6%.
In the removal of impurities separation circuit, first adopt the heavy scummer to be removed the gred, carry out three grades of multistage flotation after screening.
In bleaching with slurry operation, whiteness is controlled at 80 ° more than ISO.
The present invention adopts the wastepaper slurry to replace bleach chemical pulp, increased recycling of fiber, not only increased the economic benefit of enterprise, also make the cost of production temperature-sensitive body paper significantly descend simultaneously, but also reduced environmental pollution, reduced the investment of enterprise in the waste water removal process; In addition, the product quality obtained by the method production is good, can apply to the manufacture of heat-sensitive paper.
The accompanying drawing explanation
Fig. 1 is process chart of the present invention.
The specific embodiment
For those skilled in the art better understand, below in conjunction with Fig. 1 and embodiment, the present invention is described in further detail.
Embodiment
A kind of production method of regenerative environment-friendly temperature-sensitive body paper, its step comprises: size degradation, removal of impurities separate, bleaching with slurry, upper net forming, press dewatering, drying, top sizing, oven dry press polish, batch cut, the packed products operation, wherein, in the size degradation operation, adopt 100% wastepaper raw material to carry out size degradation, the wastepaper slurry of gained replaces traditional bleach chemical pulp, increased recycling of fiber, can reduce enterprise's production cost, improve business economic, but also reduced environmental pollution, reduced the investment of enterprise in the waste water removal process; In pulping process, beating degree is controlled at 28 ~ 36 ° of SR, and size degradation concentration is controlled at 5-6%.In the removal of impurities separation circuit, first adopt the heavy scummer to be removed the gred to crude pulp, carry out three grades of multistage flotation after screening, described screening be one roughing and twice selected, this kind of screening mode can further guarantee the quality of slurry, in addition, the heavy scummer can be removed heavy impurity in slurry, three grades of multistage flotation can slurry cleanliness factor, good by the stock quality after this operation, because adopt the wastepaper raw material to prepare paper pulp, make resulting temperature-sensitive body paper there is reproducibility, chemicals contained in the wastepaper slurry is less, produce produce in pulping process of reduced contamination, there is the feature of environmental protection.In bleaching with slurry operation, can adopt hydrogen peroxide to be bleached, also can pass in the reducing bleach tower and utilize reducing substances to carry out reducing bleach, the gained pulp brightness is controlled at 80 ° more than ISO.
Described wastepaper refers to the mixed waste paper that office collects, comprise electro-photographic paper, printing paper, invoice paper etc., this class waste paper quality is good, whiteness is high, therefore it has the higher value that is recycled, the present invention utilizes this kind of waste paper as paper pulp raw material, makes the temperature-sensitive body paper have regenerability.
In Process of Applying Glue, be to adopt the membrane type resin application methods, this resin application methods can be given water absorption resistance energy, intensity and the follow-up coating function again that paper is good.In order to remove the sicker particle in slurry, can also in production line, add hot dispersal device, the prior art that described hot dispersal device is well known to those skilled in the art.In order to remove the large a little impurity of proportion in slurry, can also increase the removal of impurities of a low concentration heavy on production line of the present invention.The fiber fines produced in production process can reclaim by fiber recovery system, and described fiber recovery system is also prior art well-known to those skilled in the art, after fiber recovery again for the production of.
The content of mentioning in above-described embodiment is not limitation of the invention, and under the prerequisite that does not break away from inventive concept of the present invention, any apparent replacement is all within protection scope of the present invention.
