不同含氮量硝化纤维素浓溶液体系的相溶性与表观粘度
SOLUBILITY AND APPARENT VISCOSITY OF DIFFERENT NITROCELLULOSE CONCENTRATED SOLUTION SYSTEMS
【摘要】 本文研究了三种不同含氮量的硝化纤维素(NC)分别与邻苯二甲酸二乙酯(DBP)、邻苯二甲酸二丁酯(DBP)、三醋酸甘油酯(TA)、二硝基甲苯(DNT)和硝化甘油(NG)组成浓溶液体系的相溶性。 实验结果得出:1)3#NC分别与DEP、DBP、TA、DNT和NG所组成体系相溶性的顺序为;3#NC/DEP>3#NC/TA>3#NC/DBP>3#NC/DNT>3#NC/NC,2)2#NC分别与DEP、DBP和TA所组成浓溶液体系相溶性的顺序为:剪切速率(?)>6×10-5秒(-1)时,2#NC/DEP>2#NC/DBP>2#NC/TA;(?)<6×10(-5)秒(-1)时。#NC/DEP>2#NC/TA>2#NC/DBP。3)1#NC分别与DEP、DBP和TA.所组成浓溶液体系相溶性的顺序为:1#NC/DEP>1#NC/DBP>1#NC/TA。结果表明,不同氮量NC浓溶液体系的η。与体系的溶度参数差值有关。
【Abstract】 The solubility of concentrated solution system composed of 1#, 2# and 3# nitrocellubose(NC) with diethyl phthalate(DEP), dibutyl phthalate(DBP) glycerin triacetate(TA), dinitrotoluene(DNT)and nitroglycerine are studied. From tlie results of these experiments it is concluded that in the order of their solubility: 1.3#NC/DEP>3# NC/TA>3#NC/DBP.2.2#NC/DEP>2#NC/ DBP>2#NC/TA(Rate of shear r>6×10-5S-1);2#NC/DEP>2#NC/TA>2#NC/ DBP(r<6×10-5S-1).3. l#NC/DEP>l#NC/DBP>l#NC/TA.It is found that the apparent viscosity of nitrocellulose concentreated solution systems has a connection with difference in solubility parameters.
