MALEIN ANGIDRID, AKRIL KISLOTASI VA POLIETILENGLIKOL ASOSIDAGI POLIKARBOKSILAT SUPERPLASTIFIKATORINING SEMENT QORISHMALARIDAGI XOSSALARIGA TA’SIRI.
Referat
Turli omillarning sintez jarayoni va mahsulot xususiyatlariga ta’siri, jumladan radikal initsiatorni bosqichma-bosqich kiritish usuli va miqdori, tizim konsentratsiyasi, harorat va reaksiya vaqti tahlil qilindi. Asosiy xomashyo sifatida akril kislota, polietilenglikol, malein angidridi va polikarboksilat superplastifikator sintez qilindi. Ularning dispersant sifatidagi nisbiy samaradorligi sement qorishmasining oquvchanligini o‘lchash orqali baholandi. Optimal texnologik ko‘rsatkichlar va xomashyo tarkibiy qismlarining nisbati aniqlandi. Natijada, yuqori sifatli beton uchun mos keladigan yangi, yuqori samarali superplastifikator ishlab chiqarildi. Sopolimerning tuzilishi infraqizil spektroskopiya yordamida tavsiflanib, tahlil qilindi. Natijalar olingan sopolimer tuzilishining ishlab chiqilgan ideal molekulyar tuzilishga mos kelishini ko‘rsatdi.
