Description
Известные способы изготовлени картона из волокнистой, размалываемой пocpeдcтвo r ролла до заданной степени измельчени массы, в которую ввод т дл нроклейки канифоль и однокислый глинозем, не позвол ют достичь необходимой прочности картона.The known methods of making cardboard from fibrous, milled rolls to a predetermined degree of grinding of the pulp, into which rosin and monoacid alumina are introduced for gluing, do not achieve the required strength of the cardboard.
В описываемом способе, с целью повышени прочности картона, в качестве проклеивающего вещества в массу ввод т водный раствор уксуснокислой соли хитозана в количестве 15-20 вес. ч. на 100 вес. ч. волокнистой массы.In the described method, in order to increase the strength of the cardboard, an aqueous solution of chitosan acetic acid in the amount of 15-20 wt. hours per 100 weight. including pulp.
Дл осуществлени этого способа изготовлени картона примен ют ролл дл размола волокнистой массы до заданной степени измельчени и пресс-машину дл формовани массы в картон.To carry out this method of making cardboard, a roll is used to grind the pulp to a predetermined degree of grinding and a press machine to form the mass into cardboard.
Волокниста масса содержит 90 вес. ч. стрзжки хромовой кожи и 10 вес. ч. линтера.The fibrous mass contains 90 wt. h. stromzka chrome skin and 10 wt. h. linter.
После размола массы до заданной степени измельчени в нее ввод т водный раствор уксуснокислой соли хитозана в указанном количестве , причем смешение массы с этой солью производ т в течение 15- 20 мин. при температуре 20-25°.After grinding the mass to a predetermined degree of grinding, an aqueous solution of chitosan acetic acid salt is introduced into it in the specified amount, and the mixture is mixed with this salt for 15-20 minutes. at a temperature of 20-25 °.
Последующее формование массы в листы картона производ т на пресс-машине по обычной технологии.Subsequent molding of the mass into sheets of cardboard is carried out on a press machine using conventional technology.
