变性淀粉浆料的评价方法

Evaluation Method of Modified Starch Size

本文在试验分析常用变性淀粉浆料性能的基础上,提出以变性淀粉对PVA浆料的代用率、上浆率、浆液粘着力、浆膜强伸度、耐磨牢度等项比值因数构成的综合评价指数与价格比相结合的公式,用计算方法来选择变性淀粉的品种和价格。

With experimental analyses on properties of conventional modified starch size, the paper gives out a formula for the evaluation of modified starch, in which property indexes are compos- itely proportioned to price ratio of modified starch in view of factors as PVA substitute, sizing percentage, size cohension, film tensile elongation and abrasion resistance, etc.
