Description
Technical field:
The present invention relates to a kind of production technology of pure natural antibacterial bamboo paste
Background technology:
Along with development, the human civilization advance of society, people are more and more higher to self Health and Living environment requirement, and uphold nature is pursued environment-protecting articles nuisanceless, that have no side effect and come into fashion.And now, many commodity, the product closely bound up such as packaging for foodstuff articles for use particularly with the human lives, for reaching the purpose of antibacterial and mouldproof, often realize by adding synthetic additive, and these synthetic additives all are the synthetic to the human body toxic side effect basically, if use for a long time, contact, health and environment are all had serious harm.How to utilize natural resources, particularly utilize bamboo resource, produce pure natural antibacterial bamboo paste, among people's consideration.
China's bamboo resource is abundant, and output is big, wide in variety,, has extensively carried out " wood substituted by bamboo " production bamboo pulp at southern area, is used for papermaking.Its bamboo pulp and paper product do not have the natural antibacterial function, only do general in, low-grade package paper and cultural paper, product purpose is narrower, added value is not high.The present bamboo pulp technological process of production is for getting the raw materials ready-boiling-blowing-washing-desanding-concentrate-chlorination-alkali treatment-hypochlorite bleaching-washing-concentrate-manufacture paper with pulp.By the common bamboo pulp of this explained hereafter, its alpha-cellulose content is 75-85%, pentosan 12-18%, ash 1-2%.Because its alpha-cellulose content is low, impurity contents such as pentosan, ash are higher, so this bamboo pulp does not have the natural antibacterial function.
Summary of the invention:
The objective of the invention is to make full use of natural bamboo resource, design a kind of alpha-cellulose content height, impurity contents such as pentosan, ash are lower, have the bamboo pulp production technology of natural antibacterial function.
Production technology of the present invention has reached above-mentioned purpose of design, and it is to improve on the basis of existing bamboo pulp production technology, and its concrete technological process is as follows:
The production technology of this pure natural antibacterial bamboo paste, comprise and get the raw materials ready, boiling, blowing, washing, desanding, concentrate, chlorination, alkali treatment, hypochlorite bleaching, washing, concentrate, manufacture paper with pulp, it is characterized in that having increased pretreatment process between procedure for preparation and cooking process, its specific operation process is as follows: (one), get the raw materials ready:
The bamboo material is cut into the bamboo chip of required specification; (2), preliminary treatment:
Carry out in boiling vessel, its technical conditions are: liquor ratio=1: 1.0-5.0, intensification condition: be warming up to 120-140 ℃ by normal temperature, heating-up time is 45-75 minute, exhaust 5-20 minute, is warming up to 120-140 ℃ again, be incubated 4-6 hour, insulation finishes, and gets rid of treatment fluid; (3), ammonium sulfite boiling:
Always use the ammonium amount: with (NH
4)
2SO
3Meter is the 20-25% of over dry bamboo material, liquor ratio=1: 2-5, buffer is 3.0-5.0%, and buffer is a kind of in urea, ammoniacal liquor, the NaOH, according to above-mentioned technical conditions, in boiling vessel, carry out the ammonium sulfite boiling, the intensification condition: rise to 110-120 ℃ by room temperature, 60 minutes heating-up times, be incubated 1 hour, float gas 5-10 minute is warming up to 140-150 ℃ again, be incubated 3 hours, exhaust is 10 minutes again, is warming up to 160-170 ℃ again, be incubated 2-4 hour, insulation finishes, blowing; (4), washing;
Slurry squeezes out black digestion liquid in the slurry through acroll press washer, washs to pH value=9.5-8.0 through wash engine again; (5), screening:
Shake frame sieve of employing sifts out not steam and separates thing and big impurity, screens through pressurized screen again; (6), desanding:
Slurry carries out in desander, adopts three sections desanding, removes chiltern and heavy seeds; (7), concentrate:
In thickener, slough the part moisture in the slurry, make slurry concentration reach 3.5-5.0%; (8), chlorination:
Technical conditions: chlorine dosage is the 60-70% of totally applied chlorine, and starching dense is 3.0-5.0%, under normal temperature condition, floats at chlorination tower or pipe and to carry out chloridized in the machine, time of chlorinating: in the chlorination tower 40-60 minute, floating in the machine at pipe was 5 minutes; (9), alkali treatment::
Technical conditions: starch dense: 3.0-5.0%, with alkali is NaOH, consumption is 2.0-5.0% to the oven dry stock amount, temperature 50-90 ℃, time 60-90 minute, in alkalization tower or bleaching machine or stock tank, slurry is carried out alkali treatment, if select for use pipe to float machine, then can directly float and carry out alkali treatment in the machine, and then slurry is put in the stock tank at pipe; (10), hypochlorite bleaching, washing:
Technical conditions: chlorine dosage is the 30-40% of totally applied chlorine, and temperature is 35-45 ℃, and time 120-260 minute, pH value=9.5-11 bleached in bleaching machine, and bleaching finishes, and can wash in bleaching machine; (11), desanding, concentrate and manufacture paper with pulp:
In desander, carry out desanding, dense for 3.0-5.0% through the thickener dehydration to starching, send pulp machine to manufacture paper with pulp then.
This technology is raw materials used to be cizu, bambusa textile, huge bamboo, fishscale bamboo, Xifeng Bamboo, sweet bamboo, bitter bamboo, support green bamboo, Fang Zhu.
According to above-mentioned technological process operation, can produce pure bamboo pulp with natural antibacterial function.The main cane part of using of bamboo material, the cane part of bamboo material mainly is made up of cellulose, hemicellulose, lignin and pectin, starch etc.Its holocellulose content is about 40-50%, and pentosan content is up to 16-22%, bamboo pulp fiber form and physics, chemical index are between needle and broad-leaved wood fiber, but it has particular structure again, different with fibers such as wood, grass, cotton, fiber crops, after particularly handling, when fiber fineness reaches higher level through special process, just possessed the exceptional function that fibers such as wood, grass, cotton, fiber crops do not have, i.e. natural antibacterial effect.Because the present invention has increased pretreatment process in existing traditional bamboo pulp technology, remove hemicellulose and other impurity in the bamboo material, the purification cellulose reaches more than 93% alpha-cellulose content, therefore, makes bamboo pulp have the natural antibacterial function.Utilize the bamboo pulp of explained hereafter of the present invention to make Related product, do not need to add artificial synthetic Fungicidal substance, can reach sterilization, sterilisation purpose, can be used for producing products such as antiseptic gauze, sanitary napkin, disinfecting paper, food wrapper, disposable container.Because the natural bamboo resource of China is inexhaustible, therefore, the present invention is a kind of suitable China's actual conditions, have the production technology of the ideal green environment-friendly products of general promotional value.
