用途:可用作造纸工业的强化施胶剂.其乳胶液稳定性好,受温度影响小,可以解决夏季施胶的困难.造纸时,可以相应减少沉淀剂的应用,降低纸张成本.同时还可与多元醇生成酯,如马来松香甘油脂、马来松香季戊四醇酯,它们是油漆、油墨、粘合剂生产的重要原料.

Application:Maleic rosin is used as
a raw material for sizing agent.when it is used as reinforcing sizing agent,its
dosage may be reduced,compaired with rosin sizing agent after saponification.Also,it
is useful to dispersed sizing agent with emulsifiers in order to reduce its dosage
and alum,which can be reduced the total cost of paper-making.Maleic rosin can
be used as a raw material of resin for paints,adhesives and inks.
