【摘要】 介绍合成木薯阳离子淀粉的影响因素,确定出合成阳离子淀粉的最佳工艺条件,表明木薯阳离子淀粉合成最佳条件是:阳离子醚化剂是淀粉用量的5%,反应温度50℃,反应时间6h;对取代度为0.03的木薯阳离子淀粉在脱墨浆中当用量为绝干浆料的0.8%时,浆料留着率和成纸强度的效果都是最好的。更多还原

【Abstract】 Introduced the factors influencing of the synthesis of tapioca cationic starch, the synthesis conditions of cationic starch is optimumed. The tapioca cationic starch is used to deink pulp, the results indicate that the optimum technological condition of tapioca cationic starch is: the dosage of etherifying agent is 5% of starch, reaction temperature 50℃, reaction time 6h,when the dosage of cationic starch with DS of 0.03 is 0.8%, the paper has the best strength and the filler retention.更多还原
