Abstract
The invention discloses a production process of low-quantitative straw wrapping paper. The process comprises the following steps of: (1) smashing bleached sulphate needle leave wood chemical pulp, adding calcium carbonate, and grinding the mixture; (2) smashing bleached sulphate broad leaf wood chemical pulp, adding calcium carbonate, and grinding the mixture; (3) uniformly blending and stirring the pulp treated in the step (1) and the step (2), and diluting the pulp; (4) preparing auxiliary materials by using cationic starch and a retention aid respectively; and (5) adding the auxiliary materials prepared in the step (4) into the diluted pulp in the step (3) respectively, preparing netting pulp by using the mixture, performing fourdrinier wire dehydration, squeezing dehydration, drying, surface sizing, drying and finishing, and rolling to obtain the straw wrapping paper. The production process has low cost, high opacity, high degree of finish and high flexibility and is environmentally friendly.
Description
Technical field
The present invention relates to a kind of papermaking, relate in particular to a kind of production technology of low quantitative suction pipe wrapping paper.
Background technology
The suction pipe wrapping paper, be mainly used in straw, the dairy produce suction pipe, package for chopsticks, toothpick packings etc. are a kind of high-grade special paper that grows up in catering industry in recent years, because advantages such as its tool cleaning, nontoxic, tasteless, easy degradeds, progressively replace plastics package at present, becoming very competitive packaging material.
The suction pipe wrapping paper is the main material of suction pipe packing, and its performance indications directly influence the effect after the suction pipe packing is finished.Its major technology index comprises: quantitatively, tightness, whiteness, tensile strength, ash, moisture content, opacity etc.
The suction pipe wrapping paper of selling on the domestic market is many with 28g/m at present
2～32g/m
2Be main, quantitatively high, consumptive material is many, the waste resource, and the while has also increased the production cost of suction pipe manufacturer.The inevitable requirement that low quantitative suction pipe wrapping paper is market development.Because of the low weight paper common intensity corresponding more much lower than heavu weights, in use easily broken; Because quantitatively low, the opacity of paper is also lower simultaneously, and tensile strength is low, can not meet the need of market.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of with low cost, and the opacity height is highly polished, and pliability is good, the production technology of the low quantitative suction pipe wrapping paper of environmental protection.
For achieving the above object, the production technology of a kind of low quantitative suction pipe wrapping paper of the present invention, step is as follows:
1. will add calcium carbonate behind the bleached sulphate needlebush chemical pulp pulping, carry out defibrination and handle;
2. will add calcium carbonate behind the bleached sulphate leaf wood chemical pulp pulping, carry out defibrination and handle;
3. the slurry mixing and stirring after 1. and 2. step being handled, diluted slurry;
4. cationic starch, retention agent are formulated as auxiliary material respectively;
5. the auxiliary material after 4. step being prepared adds respectively in the 3. described diluted slurry of step, is formulated as the online slurry, through fourdrinier wire dehydration, press dewatering, oven dry, top sizing, oven dry, ornamenting, rolls at last and is the suction pipe wrapping paper.
Step 1. in, described bleached sulphate needlebush chemical pulp and calcium carbonate mixed proportion are 4～5: 1, it mixes back defibrination to Xiao Baier beating degree is 80～86 ° of SR, weight in wet base is 6.5～7.5g.
Step 2. in, described bleached sulphate leaf wood chemical pulp and calcium carbonate mixed proportion are 4～5: 1, it mixes back defibrination to Xiao Baier beating degree is 40～45 ° of SR, weight in wet base is 1.5～2.5g.
Step 3. in, the wet end furnish after the slurry after described bleached sulphate needlebush chemical pulp defibrination is handled and the processing of bleached sulphate leaf wood chemical pulp defibrination is 4: 1, is diluted to concentration then and is 0.40%～0.45% diluted slurry;
Step 5. in, described top sizing, Cypres are wet strength agent.
Above-mentioned wet strength agent is the PPE wet strengthening resin, and concentration is 0.83～1.25%, accounts for slurry percentage 1.2～1.6%, and solution temperature is controlled at 35～45 ℃, by surface size press paper is carried out top sizing.
Compared with prior art, beneficial effect of the present invention is:
1, because the low weight paper common intensity is compared much lowerly, in use easily broken with heavu weights, adopt 100% bleached sulphate commercial wood pulp to produce, better because of its fibre property, can guarantee that the suction pipe wrapping paper becomes every indexs such as intensity of paper.
2, owing to add pearl filler, make into the paper ash branch and bring up to 10%～14%, significantly reduced the use of wood pulp, saved raw material, significantly reduced the production cost of suction pipe wrapping paper manufacturer.
3, because a large amount of addings of pearl filler have given paper higher opacity and whiteness, become the paper whiteness to reach 84～90, make paper have glossiness preferably, the pure white softness of paper.
4, owing in production process, increased top sizing, increase a small amount of wet strength agent, improved the body paper tensile strength, solved low quantitative suction pipe wrapping paper and interrupted the paper phenomenon at packaging process.
The specific embodiment
This is low quantitatively to be 18～24g/m
2Suction pipe wrapping paper production technology, step is as follows:
1. will add calcium carbonate behind the bleached sulphate needlebush chemical pulp pulping, carry out defibrination and handle;
2. will add calcium carbonate behind the bleached sulphate leaf wood chemical pulp pulping, carry out defibrination and handle;
3. the slurry mixing and stirring after 1. and 2. step being handled, diluted slurry;
4. cationic starch, retention agent are formulated as auxiliary material respectively;
5. the auxiliary material after 4. step being prepared adds respectively in the 3. described diluted slurry of step, is formulated as the online slurry, through fourdrinier wire dehydration, press dewatering, oven dry, top sizing, oven dry, ornamenting, rolls at last and is the suction pipe wrapping paper.
At first, with bleached sulphate needlebush chemical pulp size degradation in hydrabrusher, add calcium carbonate behind the pulping, mixed proportion is 4～5: 1, and adopting the double disc refiner defibrination to carry out defibrination to Xiao Baier beating degree then is 80～86 ° of SR, weight in wet base is 6.5～7.5g; With bleached sulphate leaf wood chemical pulp size degradation in hydrabrusher, add calcium carbonate behind the pulping again, mixed proportion is 4～5: 1, and adopting the double disc refiner defibrination to carry out defibrination to Xiao Baier beating degree then is 40～45 ° of SR, weight in wet base is 1.5～2.5g.
Then, bleached sulphate needlebush chemical pulp and bleached sulphate leaf wood chemical pulp after grinding are well fully mixed by a certain percentage, circulation is evenly adjusted and is entered that to destroy the forebay standby behind concentration to 3%～3.5%, slurry is diluted to 0.40%～0.45% concentration at sand trap.
Again then, add at sand trap through the flow of filter screen by 2000ml/min continuously with measuring pump starch gelatinization dilution back, and retention agent adds at low dense header box through filter screen continuously by the flow of 40～120L/h.
At last, slurry is ejected into through head box and forms wet web on the forming web, wet web is after the squeezing of 2 roads, dry through 4 groups of drying cylinders through wet web, with concentration is that 0.83～1.25% wet strength agent, temperature are carried out top sizing through surface size press to paper web at 35～45 ℃, and the paper web behind the top sizing is dried through 1 group of drying cylinder, and the paper web after the oven dry coils into paper bowl through reel machine, be obbbin with paper bowl through the cutting machine cutting and rewinding again, the obbbin behind the cutting and rewinding is a finished paper through packing case or pallet packing.
