Low shives content it is low kemimekanikaruparupu of the divination water break Characteristic, bulky of minute material content

摘要

(57) Abstract kemimekanikaruparupu in order to use for the production of the paper or board product where the high creasing Characteristic, bulky pulp is desired. Even when 60 and long fiber content between 75%, being many, 14% minute material content, the pulp which has the shives content which is lower than 0.5% being, lowest rihuainingu it is done to the freshness of 600mlCSF, at the same time has the pulling characteristic of 10kNm/kg at least. a) the tip/chip impregnation is done with the lignin softening chemicals; b) you preheat the said tip/chip; c) being manner in order to produce the pulp which the said tip/chip includes the fact that rihuainingu it does in the paper manufacture pulp and catches, the said tip/chip being many, impregnation and it is heated over the total time of 4 parts; a) the thermal impregnation liquid which at least has the temperature of the 130 is used; b) you preheat the said tip/chip in the temperature which exceeds lignin softening temperature; c) the said pulp one or rihuainingu is done at phase above that, that first or the only phase essentially is run independently at the same pressure as preheating process and the same temperature; At the same time when you preheat in the 135 and using the same machinery the same shives content is achieved at least 50% of the energy entry which is necessary and being many, with 90% all the energy entries the manner which the said pulp rihuainingu is done.
