本人化学知识浅薄,最近遇到一个问题特来贵版求助各位高人.
Melamine-Urea-Formaldehyde(MUF),也就是三聚氰胺脲醛树脂能否在像氢氧化钾,氢氧
化钙溶液这样的高碱性溶液(pH 大概有13)中稳定存在.
请先生们赐教,感谢! | r******0

sure if u r talking about mechanical property, formaldehyde emission or
something else. | M***7

Actually, the Melamine-Urea-Formaldehyde(MUF) is the shell material of a
type of microcapsule encapsulating some special core materials.We want to
use these microcapsules with different core materials in a high-alkali
environment such as KOH,NaOH or Ca(OH)2 solution with a pH aroud 12 at 70-
80C degrees. Certainly, we would like to see these microcapsules with
Melamine-Urea-Formaldehyde(MUF) shell could remain stable in high-alkali
environment as long a |
