Za a iya Ƙara MTMS Kai tsaye zuwa Tsarin Ruwa na Ruwa?

Ƙarin kai tsaye zai iya haifar da hydrolysis wanda bai kai ba da kuma narkewa. Yi amfani da ingantacciyar hanyar haɗawa da tantance daidaiton tsari da sakin methanol.

Menene Bambancin Tsakanin MTMS da MTES?

MTMS ya ƙunshi ƙungiyoyin methoxy, yayin da methyltriethoxysilane (MTES) ya ƙunshi ƙungiyoyin ethoxy. MTMS gabaɗaya yana amsawa da sauri da ruwa a ƙarƙashin kamanni yanayi. Sauya yana buƙatar kimanta aikin hydrolysis da tsarin warkewa.

Shin MTMS zai iya maye gurbin Aminosilane ko Epoxysilane?

Ba ta atomatik ba. MTMS yana da madaidaicin methyl, yayin da aminosilanes da epoxysilanes suna ɗaukar ƙarin ƙungiyoyin kwayoyin halitta masu amsawa. Zaɓi silane bisa ga ma'auni, resin chemistry da injin warkewa.
