膏状强化施胶剂的研究

<正>本文介绍了膏状强化施胶剂的制备工艺和应用。膏状强化施胶剂的松香颗粒在0.1～0.2μm之间,与日本同类产品的松香颗粒大小相同。试验结果表明,它具有进一步降低松香和硫酸铝的用量,对于天然松香胶可分别降低66％和55％,对于普通马来酐松香胶可分别降低43％和21％;它具有良好的稳定性和一定的流动性,所以便于贮存、运输和使用,是目前较为理想的纸张施胶剂。

THE FORTIFIED PASTE SIZE

This paper reports on the preparation and application of the fortified paste size. Data obtained through GC analysis, IR determination and electronmicro-scopic observation all showed the good sizing quality of the fortified paste size. The volume of the rosin particle in the paste size was between 0.1 to 0.2um, the same as similar products in Japan. Using fortified paste size, the expense of rosin and aluminium sulfate can be reduced respectively by 66% and 55% for natural rosin size and 43% and 21% for maleated rosin size in the sizing process. Since fortified paste size is stabilety and somewhat fluidic, it can be stored for a long time (1~2 years) and used conveniently. Practices show that up to now fortified paste size is a very good kind of paper size.
