SELLYULOZA ASOSIDAGI CHIQINDILARDAN EKOLOGIK TOZA VA BARQAROR KOMPOZIT MATERIALLAR ISHLAB CHIQARISH
Abstract
Qattiq maishiy chiqindilarni boshqarish tuproq, suv va havoning ifloslanishiga olib keladigan organik materiallarning to‘planishi va parchalanishi tufayli muhim global ekologik muammoga aylandi. Ushbu tadqiqot mahalliy yog‘och va plastmassa chiqindilaridan foydalanib yog‘och-polimer kompozitlar (WPC) ishlab chiqarish orqali maishiy chiqindilardan barqaror foydalanishga qaratilgan. Toshkent viloyatidagi poligonlardan yig‘ilgan chiqindi materiallar - polietilen paketlar, shoxlar, novdalar va barglar yuvish, ekstruziya va issiq presslash orqali qayta ishlanib, WPC namunalarini hosil qildi. Yog‘och chiqindilarining har xil turlari va tarkibining WPC fizik-mexanik xossalariga ta’siri G‘azalkent tumanida tabiiy nurash sharoitida olti oy davomida o‘rganildi. Tajriba natijalari shuni ko‘rsatdiki, yong‘oq yog‘ochi unining miqdorini oshirish va 6% MAPPS (malein angidridi-polipropilen) qo‘shish kompozitlarning fazalararo adgeziyasi, cho‘zilishdagi mustahkamligi va qattiqligini yaxshiladi. Biroq, tabiiy nurashning uzoq muddatli ta’siri mikroyoriqlarning paydo bo‘lishiga olib keldi, bu esa uzilish moduli va elastiklikning asta-sekin pasayishiga sabab bo‘ldi. Umuman olganda, tadqiqotlar shuni tasdiqlaydiki, qattiq maishiy chiqindilar ekologik toza WPC ishlab chiqarish uchun qimmatli xomashyo bo‘lib xizmat qilishi mumkin, bu esa chiqindi poligonlarining to‘planishini kamaytirish va to‘shama, to‘siq va qoplama kabi tashqi qurilish uchun chidamli materiallar bilan ta’minlashning istiqbolli yechimini taklif etadi.
