Abstract
Oltingugurtli bogʻlovchilarning kristallanish tezligi va moʻrtligi ularni mustahkamlashda asosiy muammo hisoblanadi. Maqsad — aromatik birikmalar yordamida erigan oltingugurtni modifikatsiyalash va siqilish mustahkamligi yuqori kompozit olish edi. Tajribalar laboratoriya sharoitida olib borildi; tarkiblar 140–160 °C da aralashtirildi, FTIR-spektroskopiya va CHN tahlili bilan tuzilma tekshirildi, namunalar pressda siqilish sinovidan oʻtkazildi. Aromatik qoʻshimcha 0,1 mass.% dan 0,5 mass.% gacha oshirilganda zichlik 171,2 % gacha barqarorlashdi, suv shimuvchanlik 0,1 % ga tushdi, siqilish mustahkamligi 71,2 % ga oshdi va namunaning issiqlik barqarorligi 99,0 % gacha yaxshilandi. Natijalar aromatik modifikatsiya oltingugurtli kompozitning kristall panjarasini mayda donali holatga oʻtkazishini koʻrsatdi. Shu yondashuv chiqindi oltingugurtni samarali bogʻlovchiga aylantirishga asos yaratadi.
