1)  fortified rosin
强化松香
1.
This paper studies the influence of modifiers on the properties of fortified rosin,the reaction mechanism of modification and the leading compositions of fortified rosin by using maleic and fumaric acids as modifiers.
研究结果表明:①强化松香的酸值,皂化值和软化点都随着加成量的增加而提高,基本上呈线性关系:②强化松香的马来酸或富马酸的加成量应控制在3%~5%范围内为宜:③富马酸的主要成分为松香酸和富马海松酸,马来松香的主要成分除了松香酸和马来海松酸以外,还有马来海松酸酐和马来海松酸酯;④在加成量相同的情况下:富马松香与马来松香相比具有较低的软化点和皂化值,却有较高的酸值,有利于改善强化松香胶和分散松香胶的质量。
2)  semitransparent forified rosin size
强化松香胶
3)  cyfor,fortified rosin size,mersize,hardened rosin glue
强化松香胶料
4)  FORTIFIED ROSIN
强力松香
5)  dispersion type fortified rosin size
分散型强化松香胶
1.
ourteen patents on the preparation of dispersion type fortified rosin sizes are being briefly revieved.
由于分散型强化松香胶拥有较佳的施胶效果,近年来很多纸厂均已采用分散型强化松香胶取代松香皂和普通强化松香胶。
6)  hydrogenated rosin
氢化松香
1.
In the presence of alkaline soap as emulsifier and catalyst, hydrogenated rosin sucrose esters (HRSE) were synthesized by transesterification reaction of hydrogenated rosin ethyl ester and sucrose under the conditions of (125±1)℃,molar ratio of hydrogenated rosin ethyl ester to sucrose 1 ∶1, pressure 0.
090MPa及无溶剂的条件下,通过氢化松香乙酯与蔗糖的酯交换反应合成了氢化松香蔗糖酯(HRSE)。
2.
The hydrogenated rosin (HR) and hydroxyethyl methacrylate (HEMA) based ester was synthesized in one step method.
用一步法制备了氢化松香与甲基丙烯酸β-羟乙酯(HEMA)酯化物,结果表明,以对苯二酚为阻聚剂,氧化锌为催化剂,用量为氢化松香的1%,反应温度240℃,氢化松香与HEMA的摩尔比为1∶1。
3.
By analyzing a plenty of practical production data,suitable conditions for controlling the product color during the production of hydrogenated rosin are concluded to be super grade rosin as raw material,melting time 5h and melting temperature 130150,molten rosin flow rate 400L/h,reaction temperature 240250.
另外还应尽量减少反应系统中的CO、CO2、SO2、重金属离子的含量,避免有色油类和空气进入反应系统,最后对产品进行水蒸气蒸馏,能得到颜色较浅的氢化松香产品。
