Description
Technical field
The utility model relates to the approach system technical field of toilet paper machine paper pulp, particularly a kind of double-layer headbox.
Background technology
Toilet paper is all representing paper product widely with tissue, and they are mainly used in personal consumption and public arena consumption, go to toilet with toilet paper, napkin paper, face tissue, tissue etc., have incorporated people's life, and are indispensable.Along with development of times, people are also more and more higher to the quality requirement of toilet paper, and better development will be expected by enterprise, and the quality that improves its toilet paper brand is the basis of capturing market, and the production efficiency and the work quality that effectively improve self simultaneously are important means.The toilet paper machine main trend is faster towards speed, and efficient is higher, and the direction of better quality develops.
All kinds of tissues and toilet paper quantitatively differ, and have gently to 5g/m
2, 35g/m weighs
2, the quantitative of general toilet paper is 11-17g/m
2, with this visible toilet paper quantitatively is very low.Low quantitative stationery is wrinkling if desired in process of production, and the problem of Shenging can directly influence into the quality of paper and the operating efficiency of production so thereupon.
Wrinkling is very important one technology during toilet paper is produced, and wrinkling effect directly influences feel, outward appearance and the physical property thereof of toilet paper.In the toilet paper production process, the factor that influences creping is a lot, as chemical assistant, doctor blade holder angle, wing material and slurry etc.And slurry is as influencing one of key factor of corrugation effect, and we need think better of and treat.Wrinkling is to stick to the gauffer that the paper web of dryer surface forms under the effect of drying cylinder and scraper.Here relate to drying cylinder and scraper, the character of both and slurry itself together affects corrugation effect.Because the wrinkling of paper web carries out at drying cylinder, and the tackness of different slurries on drying cylinder has nothing in common with each other, thereby wrinkling quality is also inequality.If the sheet fiber that is attached on the drying cylinder is shorter, scraper is scraped paper web disconnectedly easily so, and a large amount of staple fibres can produce and fly hair, and disconnected paper not only reduces production efficiency, and influences the environment in workshop easily.So just needing increases the intensity that paper web is attached to this one side of drying cylinder, for gaining in strength, just require to use more long fiber, but long fiber can make formation of sheet and bulk etc. be affected too much again, has increased cost simultaneously.
In addition, when considering corrugation effect, we also need to consider the bulk of toilet paper, water imbibition and good hand feeling, will certainly cause some theoretic conflicts so, can improve bulk by the consumption that increases staple fibre as us, but this can make the intensity of paper web, wrinkling being subjected to have a strong impact on.Thereby, be that a realistic meaning is also had in the research of the cost bulk that exchanges paper for, water imbibition etc. very much as why not to reduce paper strength.
Through the analysis to the toilet paper quality requirement, traditional head box can't be realized above-mentioned purpose at present.
