Abstract
The invention discloses a production process of low weight ultra-thin tissue paper. The production process is characterized in that a bratsk needle leaf wood pulp board and a sulfate bleached chemical straw pulp board which are 25-35% and 65-75% in percentage by mass respectively are adopted, the bratsk needle leaf wood pulp board and the sulfate bleached chemical straw pulp board are subjected to pulping, proportioning, slushing, on-net papermaking, squeezing, drying, quality controlling and baling to be prepared into the low weight ultra-thin tissue paper; the bratsk needle leaf wood pulp board and the sulfate bleached chemical straw pulp board are subjected to continuous high-viscosity beating respectively through double disc refiners with Type 4 abrasive discs, the abrasive teeth of the abrasive discs are arranged in an S shape, the tooth width ranges from 2.0 to 2.4 mm, the width of intertooth space ranges from 1.7 to 2.1 mm, and the tooth depth ranges from 3.4 to 3.8 mm; and the paper making net used in the step of on-net papermaking is a 20-piece double-row heald frame three-layer polyester wire mesh. The production process overcomes the defects of high production cost and poor quality of the low weight ultra-thin tissue paper in the present market, reduces production cost of ultra-thin tissue paper, and ensures the good quality.
Description
Technical field
The present invention relates to a kind of production technology of low quantitative ultrathin tissue paper.
Background technology
Low quantitative ultrathin tissue paper is as a kind of speciality paper, have that intensity is high, clear transparent, flexibility, nontoxic, but the waste paper natural degradation can be directly used in the packings such as light industry commodity, food, medicine, fruit Saran wrap, gold and silver utensil, industrial art, leather shoes.Existing domestic fruit supermarket quick-frozen food, cake packaging, domestic refrigerator preservative film, the a large amount of use gathered second envelope material film, and the use of these products has not only consumed a large amount of petroleum resources, and discarded object non-degradable under nature, cause " white pollution ", environment is caused very big impact.Super tissue paper will can solve this problem to replace plastic film packaging paper to utilize aboundresources, reproducible string to go out to hang down quantitatively through deep processing development.And low quantitatively ultrathin high-grade tissue paper, the high-grade special paper that belongs to internal blank at present, China's papermaking product is at present mainly to produce low and middle-grade paper as main, the slim speciality paper of a considerable amount of top grades still needs a large amount of imports, paper far can not adapt to the change and progress of China paper consumption market, one of its reason is that the production of China's tissue paper yields poorly, and cost can be in any more, and this is because the papermaking wire-cloth of domestic ultrathin tissue paper production usefulness is that copper mesh causes.The copper mesh tension stress is limited, and tension is easily broken, and crosses pine and easily produces the net ditch, and wear no resistance, and service life is short, therefore maintenance cost is high, and it is unstable to cause copying paper quality.
In addition, existing low quantitative ultrathin tissue paper is produced used Bradley thatch gram softwood pulp, mainly take red, kahikatea and larch as raw material, have fiber tubbiness, the poly-high characteristics of saccharogenesis content, easily cause fibr tissue expansion and the eyelet paper defects problem of low quantitative ultrathin tissue paper.
Summary of the invention
The production technology that the purpose of this invention is to provide a kind of low quantitative ultrathin tissue paper, it is high that it has solved existing low quantitative ultrathin tissue paper production cost on the market, easily produces eyelet paper defects, expansion problem, bad, the problems such as main dependence on import.The low quantitative ultrathin tissue paper of its production not only has neat oil, reproducible good characteristic, and production cost is low, and is convenient and practical, biodegradable, filled up domestic blank, for country saves a large amount of forest reserves.
A kind of production technology of low quantitative ultrathin tissue paper comprises successively that making beating, with slurry, punching slurry, online are manufactured paper with pulp, squeezed, drying, Quality Control, baling operation, and the used papermaking wire-cloth of step of manufacturing paper with pulp of surfing the Net is three layers of polyester webs of 20 heald frames.Use this polyester webs to substitute existing copper mesh as papermaking wire-cloth, have that tension stress is strong, abrasion resistance is high, the characteristic of long service life, and the braid method that adopts three layers of 20 heald frames can solve the poor shortcoming of polyester webs water separation capability, the stability of copying paper quality can be improved, nearly 2,500,000 yuan can be saved production cost simultaneously.
The making beating raw material adopts Bradley thatch gram needlebush pulpboard and sulfate bleached chemical pulp plate, and with the double plate of abrasive disc model 4 types mill it is carried out respectively continuous high shiny beating, this abrasive disc roll flute is that the S type is arranged the facewidth 2.2 ± 0.2mm, the wide 1.9 ± 0.2mm of roller seating space, tooth depth 3.6 ± 0.2mm.Conditions of beating advances to starch concentration 4-5%, and pulp flow is 40-50m
3/ h; 60-65 ° of SR of Bradley thatch gram softwood pulp beating degree, fiber wet weight 6-7g; 55-60 ° of SR of sulfate bleached chemical straw pulp beating degree, the heavy 4-5g of fiber.Restrain softwood pulp fiber tubbiness, gather into the high characteristics of candy content according to the Bradley thatch, employing is with the double plate of this abrasive disc roll flute mill and cooperate above conditions of beating, can improve the fiber brooming rate of Bradley thatch gram softwood pulp, reduce fines content, prevent fiber loss, therefore effectively solved fibr tissue expansion and the eyelet paper defects problem of low quantitative ultrathin tissue paper, promoted the capability and performance of Russian Bradley thatch gram oar.
The mass percent of making beating raw material Bradley thatch gram needlebush pulpboard and sulfate bleached chemical pulp plate is respectively 30 ± 5% and 70 ± 5%.The long and short proportion of fibers that adopts this proportioning to obtain to suit after the fiber brooming, makes slim paper simultaneously higher intensity and toughness can be arranged having ultra-thin thinness.
The online online mass concentration 0.03% in the operation of manufacturing paper with pulp, grenadine is copied fast 600-700m/min, the quantitative 12-22g/m of paper pulp
2Above papermaking process parameter guarantees the thinness that slim paper is produced.
Add titanium dioxide in the with slurry operation, consumption is 50Kg/ ton slurry, and it is so that Paper White Degree is good, intensity is high, glossy, frivolous and smooth, opacity is high.
Add CaCO in the with slurry operation
3, consumption is 150Kg/ ton slurry, it can improve paper opacity, whiteness and brightness, improves paper smoothness, the uniformity and pliability.
This technique also comprises the broken recovery system, and soon the broken in the baling operation drops into the with slurry pond again and carries out reuse after high-concentration pulper is smashed, and the slurry mass ratio of waste stuff and mixed paper is 90%:10%.
This technique also comprises Save All System, be about to that online is manufactured paper with pulp and squeezing process in plain boiled water reclaim for making beating, with slurry and rush slurry process.
The recovery utilization rate that is arranged so that broken and plain boiled water of broken recovery system and Save All System improves, not only environmental protection but also raising output.
Should low quantitative ultrathin tissue paper production technology compare with the product of existing technique, copy the paper stability good, can effectively reduce production costs, and the finished product of its production can have higher intensity and toughness simultaneously having ultra-thin thinness, and it is good that it has whiteness, glossiness, smoothness, opacity, lightweight good quality.
