摘要
烷基糖苷能够显著降低水溶液的表面张力,具有乳化、分散、润湿等诸多性能,广泛用作食品、农药的乳化分散剂。淀粉十二烷基糖苷以甘薯为淀粉来源,将其用作墙衣分散剂,考察其在墙衣料浆中的分散性,结果表明:淀粉十二烷基糖苷对墙衣具有良好的分散润湿性、流动性及分散稳定性,较萘磺酸盐甲醛缩合物更适合分散植物纤维体系,也较辛基酚聚氧乙烯醚润湿性和稳定性更好。
Alkyl glycosides can significantly reduce the surface tension of aqueous solutions,have various properties such as emulsification,dispersion,and wetting,and are widely used as emulsifying and dispersing agents for food and pesticides.Starch dodecyl glycoside is used as wall coating dispersant with sweet potato as starch source.The dispersibility in wall coating slurry is studied.The results show that starch dodecyl glycosides have good dispersion,wettability,fluidity and stability for wall coatings.It is more suitable for dispersing plant fiber systems than naphthalenesulfonate formaldehyde condensate,and it has better wettability and stability than octylphenol polyoxyethylene ether.
