化學(xué)配方數(shù)據(jù)庫(kù)

配方類型：	EMULSIONS & DISPERSIONS
配方說(shuō)明：	DDI Diisocynate Emulsion
配方組成：
配制方法：	DDI diisocyanate can be emulsified in water without auxiliary emulsifiers if extremely high shear agitation is used. However, for a more physically stable emulsion, one of the following three emulsifier compositions would be suitable: $G: "Tween" 20+ "Span" 20 "Tween" 80+ "Span" 80 "Igepal" CO-530 While the required ratio of emulsifier to DDI diisocyanate will vary depending on the local water source, a recommended starting point would be 7-10% emulsifier based on the DDI diisocyanate solids content. This level is used for simple agitation emulsification, lower levels of emulsifier can be tolerated as mechanical agitation i s increased.
