Abstract
The invention discloses a production method applied to latex fiberboard production by taking linters as raw materials. The method comprises the following steps: preparing pulp raw materials, wherein the pulp raw materials comprise the following components based on total mass percent of 100%: 10-20 mass percent of linters which replace chemimechanical pulp or/and long fiber pulp, and the balance of chemimechanical pulp or/and long fiber pulp which is not substituted; and with the pulp raw materials as pulp raw materials for producing latex fiberboards, manufacturing the latex fiberboards according to a conventional process for manufacturing the latex fiberboards. The produced latex fiberboards accord with physical property indexes of the latex fiberboards, the quality of the latex fiberboards is close to that of latex fiberboards manufactured by using bleached sulfate pulp or chemimechanical pulp and is not greatly reduced. Therefore, the amount of the bleached sulfate pulp or chemimechanical pulp is reduced, the production cost is reduced, the yield of the produced latex fiberboards is increased, and the vehicle speed and yield of the latex fiberboard production line are increased.
Description
Technical field:
The invention belongs to latex Fibreboard Production field, being specifically related to a kind of cotton linter that adopts is the production method that raw material is applied to latex Fibreboard Production.
Background technology:
Bleached kraft pulp is long fiber plasmoid, the especially softwood pulp of representative, is the main raw material(s) of latex Fibreboard Production always.The production of latex fiberboard is higher to forming requirements, and the characteristic that bleached kraft pulp has: freedom is high, and fiber fines is less, can keep the superperformance of product.But, this slurry kind of single use, though can obtain higher intensity physical index, finished product tightness is higher, folding strength is obviously high, but because its fiber fines is less, finished product evenness and surface smoothness are difficult to meet the requirement apparent to product that client improves day by day.
Existing production technology, adopt more bleached kraft pulp be main long fiber pulp as main raw material, a small amount of chemi-mechanical pulp of adapted is produced simultaneously, or the mode that adopts aborning reduction wet end to squeeze, meet the requirement that tightness is low, by employing, reduce the mode of wet end squeezing, can cause dipping part impregnation resin content not enough, can make wet plate when entering oven dry portion, the mass dryness fraction of product is less than 40%, and drying load increases, simultaneously, the production speed of a motor vehicle is affected, and these factors have increased manufacturing cost.
Summary of the invention:
The object of this invention is to provide a kind of cotton linter that adopts is the production method that raw material is applied to latex Fibreboard Production, use cotton linter to be applied to latex Fibreboard Production, can improve the economic benefit of producing, because of the distinctive fiber properties of cotton linter, can effectively reduce the tightness of cardboard, substitute long fiber plasmoid or chemi-mechanical pulp, reduce cost of material.By using cotton linter can improve the dewatering in the process of manufacturing paper with pulp, thereby improve the wet plate mass dryness fraction before impregnation, contribute to the impregnation infiltration of dipping part, reduce the drying load of drying section.
Employing cotton linter of the present invention is the production method that raw material is applied to latex Fibreboard Production, it is characterized in that, comprises the following steps:
Slurry raw material: by gross mass mark 100%, comprise following component, or/and long fiber pulp, remaining is that not replaced chemi-mechanical pulp is or/and long fiber pulp with the cotton linter instead of chemical mechanical pulp that accounts for gross mass mark 10～20%;
Using above-mentioned slurry raw material as the slurry raw material of latex Fibreboard Production, according to the common process of latex fiberboard processed, produce latex fiberboard.
Described slurry raw material is preferably: by gross mass mark 100%, by long fiber pulp (masson pine, make slurry and bleached cotton starch etc. containing discarded paper substrate composite soft packaging material) 60%～70%, chemi-mechanical pulp 10%～20% and cotton linter 10%～20% form.
Described slurry raw material is preferably: by gross mass mark 100%, the long fiber pulp 60% after the paper substrate partial hydrolysis of masson pine 10%, milk box, chemi-mechanical pulp 10% and cotton linter 20%, consist of.
Cotton linter mainly refers to fiber remaining on the gross cottonseed utilizing after cotton ginning, the cotton linter peeling from the classification of gross cottonseed surface with delinter, and the cotton linter in the present invention refers to wherein Er road suede and/or three road suedes.It has following characteristic: fiber is short and thick, generally only has 2-3 millimeter, and length only reaches 30 times of left and right of width, and content of cellulose is more than 90%, slurry freedom high (freedom is greater than 800CSF).
The cotton linter using in the present invention is to substitute long fiber pulp for part, or part substitutes or replacing whole chemi-mechanical pulp, prepare burden kind and the consumption of the batching when all with masson pine of the long fiber pulp of remainder (or not having) and other is identical.Innovative point of the present invention is to use cotton linter partly to substitute long fiber plasmoid of the prior art or/and chemi-mechanical pulp.
Of the present inventionly using the slurry raw material of above-mentioned slurry raw material as latex Fibreboard Production, according to the common process of latex fiberboard processed, produce latex fiberboard and specifically above-mentioned slurry raw material and appropriate water are put into hydrabrusher pulping, defibrination after desanding removal of impurities, in pond with slurry, add again chemical adjuvant and dyestuff with slurry, carry again in pulp storage tank, after wet end moulding and dehydration, again at dipping part impregnation, then dry, surface finish, as top sizing and soft calendaring, by these common process, and make the latex fiberboard of finished product.
The present invention utilizes cotton linter raw material, part substitutes long fiber pulp, or part substitutes or replacing whole chemi-mechanical pulp, produce latex fiberboard, this latex fiberboard meets latex fiberboard physical performance index, the quality of this product is more approaching with the mass ratio of the latex fiberboard of manufacturing with masson pine or chemi-mechanical pulp, do not occur significantly reducing, therefore with raw material of the present invention, manufacture latex fiberboard, reduced the consumption of masson pine or chemi-mechanical pulp, reduce production costs, improved the yield rate of latex Fibreboard Production, the latex fibreboard production line speed of a motor vehicle and output have been improved, product quality meets QUALITY STANDARD simultaneously, have broad application prospects.
The specific embodiment:
Following examples are to further illustrate of the present invention, rather than limitation of the present invention.
Embodiment 1:
The employing cotton linter of the present embodiment is the production method that raw material is applied to latex Fibreboard Production, use following wet end furnish to produce latex fiberboard: by gross mass mark 100%, by long fiber pulp 70% (comprising the long fiber pulp 60% after the paper substrate partial hydrolysis of masson pine 10% and milk box), chemi-mechanical pulp (yellow core card slurry) 10% and cotton linter 20%, to be formed.
