Abstract

So‘nggi yillarda to‘qimachilik va charm sanoatida materiallarning ekspluatatsion xossalarini yaxshilash maqsadida kremniyorganik birikmalar asosida tayyorlangan himoya qoplamalarini qo‘llash keng tarqalmoqda. Bunday qoplamalar material sirtiga suvni o‘tkazmaydigan, chang va iflosliklarni yopiqlikdan himoya qiluvchi, hamda issiqlikka chidamli noorganik-organik qatlam hosil qiladi. Kremniyorganik moddalar tarkibida asosiy skeletni –Si–O–Si– bog‘lari tashkil etib, ularga ulangan metil, etil yoki boshqa organik guruhlar sirt energiyasini keskin kamaytiradi. Natijada qoplama hosil qilingan materialda gidrofoblik darajasi ortadi.
