Description
[technical field]
The invention belongs to tobacco processing techniques, relate to papermaking-method reconstituted tobaccos production field, that one first utilizes mixed slurry to adsorb calcium carbonate formation compound, in conjunction with starch, coating modification is carried out to compound again, make wadding aggressiveness, then use surfactant, crosslinking agent to wadding aggressiveness surface modification and disposal of stability respectively, finally improve the method for the effective retention of calcium carbonate in papermaking-method reconstituted tobaccos by polynary retention principal curvature system.
[background technology]
Reconstituted tobacco is also known as recombination tobacco leaf, reconstituted tobacoo, homogeneous tobacco leaf etc.The external use papermaking-method reconstituted tobaccos that begins one's study from mid-term in last century, domestic papermaking-method reconstituted tobaccos industry development is all more late with starting, but development speed and technological progress are all very fast, papermaking-method reconstituted tobaccos all has stronger functional form effect in saving raw tobacco material, lowering harm and decreasing coking, flavouring humectation, outstanding cigarette product style and features etc., and current papermaking-method reconstituted tobaccos has become the important and indispensable raw material of Chinese-style cigarette.
The processing mode of reconstituted tobacco generally has following several, and roll-in method, paper process, thick slurry processes, impregnating method, microplate method etc., wherein papermaking-method reconstituted tobaccos is topmost processing mode.Papermaking-method reconstituted tobaccos mainly with the offal produced in cigarette and beating and double roasting process, fragment, offal, ash rod, discarded tobacco leaf etc. for raw material, be equipped with other non-tobacco fibrous raw material, additives etc., through lixiviate, concentrate, pull an oar, manufacture paper with pulp, be coated with, dry, the process such as to cut, make the process of shape close to natural tobacco.
Offal and fragment tobacco business papermaking-method reconstituted tobaccos main tobacco material used.Offal mainly provides the fiber of reconstituted tobacco, and fragment can provide good aroma substance, is the main source of reconstituted tobacco fragrance matter.But the content of cellulose in the tobacco material such as offal and fragment is lower, the effect adding non-fiber mainly improves content of cellulose in slurry, increases the physical strength of sheet base, is convenient to following process.At present, domestic reconstituted tobacco manufacturing enterprise all uses the non-tobacco fibrous raw materials such as wood pulp.
Calcium carbonate is additive important in papermaking-method reconstituted tobaccos production process, and according to the difference of calcium carbonate production method, calcium carbonate is divided into precipitated calcium carbonate, powdered whiting, gel calcium carbonate and crystal calcium carbonate.At present, most of papermaking-method reconstituted tobaccos manufacturing enterprise all adopts precipitated calcium carbonate as filler.Calcium carbonate effectively can improve physical property and the permeance property of sheet base, reduces the substance release amount such as reconstituted tobacco product tar and CO.
Traditional using method of calcium carbonate is generally directly join in tobacco mixed slurry according to certain design proportion, makes it to mix with slurry by mechanical agitation.Compared to tobacco slurry, the particle diameter of calcium carbonate is very little, and in the process of manufacturing paper with pulp, wet end runs off serious, therefore, only by the pure physisorption between calcium carbonate and tobacco slurry, is difficult to the effective flocculation reached therebetween, causes a large amount of calcium carbonate to run off in vain.In actual production, the use amount of calcium carbonate is just needed to strengthen in order to improve retention, its result often causes more calcium polycarbonate to be lost in plain boiled water, add cost, reduce reuse plain boiled water quality, add sewage disposal energy consumption and ton product water consumption, and in fact the effective retention of calcium carbonate does not significantly improve.
In actual production, the general effective rate of utilization adopting the size of retention to weigh calcium carbonate in papermaking-method reconstituted tobaccos process.At present, papermaking-method reconstituted tobaccos is in the process of adding calcium carbonate, and the problem that ubiquity retention is low, directly affects reconstituted tobacco product quality.In recent years, difficult point and the focus that calcium carbonate retention rate research is papermaking-method reconstituted tobaccos area research is always improved.
Research shows, (a) adds the quality that outer fibre can improve calcium carbonate retention rate and sheet base.Patent CN201210190343 describes one and in tobacco material slurry, adds wood pulp cellulose, to improve the method for reconstituted tobacco paper substrate quality when handsheet.
B () changes calcium carbonate addition manner, can improve the retention of calcium carbonate.Patent CN 101822419 A describes a kind of by adding soluble carbonate salt solution in the slurry, improves the method for calcium carbonate retention rate in papermaking-method reconstituted tobaccos sheet base.Patent CN 103919271 A describes one and is first mixed with calcium carbonate by tobacco pulp and pull an oar, then adds plus fiber and shitosan retention agent, to improve the method for calcium carbonate retention rate.
C () is often carried out covering property to filler and is modified the retention studied and improve filler in paper industry, Wang Huiping reports and adopts epoxychloropropane Cross-linking Cationic Starch to carry out coating modification to grinding calcium carbonate, can promote high fill out paper tensile strength, bursting strength and filler retention [Chinese papermaking, 2010,1 (29)]; Shen Jing reports employing carboxymethyl cellulose/aluminum sulfate and carries out coated to calcium carbonate, improves high mechanical property and calcium carbonate retention rate (Carbohydrate Polymer, 2010,81) of filling out paper.But it is relatively less in such research of tobacco manufacture field, it is that coating agent carries out parcel process to pearl filler that patent CN 103859576 A describes a kind of native potato starch that adopts, charge adjusting agent is used to regulate pulp fiber surface charge, the filler of parcel is added in tobacco slurry, to improve the method for fiber and filler retention.
D () utilizes retention agent can improve the retention of calcium carbonate in sheet base to a certain extent, wherein shitosan, guar gum etc. have good retention and drainage effect.Patent CN 102715641 A describes a kind of by adding in handsheet step the method that calcium carbonate, wood pulp cellulose and guar gum improve reconstituted tobacco paper substrate quality in tobacco slurry.Patent CN 102715642 A describes a kind of raising and in tobacco slurry, adds calcium carbonate and guar gum to improve the method for reconstituted tobacco paper substrate quality in handsheet step.Hu Huiren reports the retention aid and filtering aid system raising tobacco slurry of employing shitosan/bentonite microparticles binary and the retention of filler, improves the quality [Chinese papermaking, 2011,4 (30)] of tobacco leaf substrate.At present, most domestic reconstituted tobacco enterprise uses shitosan, guar gum etc. to improve retention aid and filtering aid performance all aborning.
Other aspects, patent CN 103829364 A describes a kind of by salt coating fluid, improves the retention of calcium carbonate on reconstituted tobacco and distribution consistency degree, thus improves the method for the humid keeping performance of reconstituted tobacco, physical property and sensory evaluating smoking's effect.
Above-mentioned research shows, by changing calcium carbonate addition manner, adding wood pulp cellulose and use the measure such as shitosan, guar gum auxiliary agent, although can improve retention and the sheet base physical index of calcium carbonate in sheet base to a certain extent.But mostly rest on laboratory stage, deposit the problems such as middle operability is not strong, result of use is not good in actual production process, cause effective retention of calcium carbonate in actual production time slice base still not reach expection requirement.The present invention first utilizes the mixed slurry absorption calcium carbonate such as wood pulp, offal and chopped fiber to form compound, then carries out coating modification in conjunction with starch to compound, makes wadding aggressiveness, with surfactant, crosslinking agent to wadding aggressiveness surface modification.The last retention comprehensively improving calcium carbonate by polynary retention principal curvature system, studies carefully according to our literature survey and yet there are no relevant report.
