Annotatsiya
Ushbu maqolada yog‘ochga nisbatan yopishish samaradorligi oshirilgan, suyuq shisha (natriy silikat Na₂O·nSiO₂) asosida tayyorlangan modifikatsiyalangan, ekologik xavfsiz elim olish masalasi ko‘rib chiqilgan. Ishlatilgan natriy silikat GOST 13078–81 va TU 6-18-003-87 talablariga to‘liq javob beradi, uning silikat moduli 2,6–2,8, quruq qoldiqning massaviy ulushi esa 31–33% ni tashkil qiladi. Modifikator sifatida tiomochevina va glitserin asosida sintez qilingan oligomer qo‘llanilgan. Tajribalar modifikatorni suyuq shisha bilan turli massaviy nisbatlarda (5%, 10%, 15%) aralashtirish orqali o‘tkazildi. Tajriba natijalari shuni ko‘rsatdiki, modifikatsiya jarayoni elimning reologik va mexanik xususiyatlarini sezilarli darajada yaxshilaydi. Modifikatorning optimal miqdori (10%) da yopishish mustahkamligi 2,28 MPa dan 3,15 MPa gacha (27,6%) oshgan, suvga chidamlilik esa 62% dan 82% gacha ko‘tarilgan. Shu bilan birga, elimning qovushoqligi 230 mPa·s ni tashkil etgan bo‘lib, bu GOST 13078–81 da belgilangan 200–250 mPa·s sanoat me’yorlariga to‘liq mos keladi. Olingan modifikatsiyalangan elim formaldehid ajratmaydi, toksik bo‘lmagan va ekologik xavfsiz bog‘lovchi material hisoblanadi, u yog‘ochni yopishtirishda yuqori adgeziya va namlikka bardoshlilikni ta’minlaydi. Olingan natijalar modifikatsiyalangan silikat yelimlarni yog‘ochga ishlov berish, qurilish va mebel sanoatida keng qo‘llash uchun ilmiy-texnik asos yaratadi.
