Several applications of cassava starch effect on de wet end of the papermaking sizing comparison

文章介绍几种木薯淀粉在造纸湿部施胶上的应用效果比较。研究表明:①与空白样相比,添加原淀粉、阳离子淀粉、两性淀粉都能提高纸张的物理强度指标。②从物理强度指标上看,两性淀粉的效果最好,阳离子淀粉次之,原淀粉最差。③添加阳离子淀粉及两性淀粉,对环压强度有明显提高,分别提高36.7%,38.7%。④添加两性淀粉,对耐破度提高最大,达57.8%。

This paper describes the application of several tapioca effects on the Wet end of the papermaking sizing comparison. Studies show that： ①Compared with the Blank sample, add starch, cationic starch, amphoteric starch can improve the physical strength index of the paper. ②From the point of view of physical strength index, the best results amphoteric starch, cationic starch, followed by raw starch worst.③Adding cationic starch and amphoteric starch, on the ring crush strength improved significantly, increased by 36.7%,38.7%.④Add amphoteric starch, bursting improve on the most, up 57.8 percent.
