Annotatsiya

Maqolada ortofosfat kislotasi (85 %), natriy gidroksid va natriy silikat asosida bir bosqichli, past haroratli usulda natriy polifosfat–silikat kompozitsiyasini sintez qilish natijalari keltirilgan. Reaksiya aralashmasining hisoblangan mol nisbatlari Na/P = 1,62 va Si/P = 0,38 ni tashkil etadi. 120–150 °C da quritilgan va 300 °C da 1 soat polikondensatlangan mahsulotning termik xossalari argon oqimida (100 ml/min), 10 °C/min tezlikda DTG-60 derivatografida oʻrganildi. TG egri chizigʻida 775 °C gacha toʻrtta massa yoʻqotish bosqichi qayd etildi, umumiy massa yoʻqotish 7,97 % ni tashkil qildi. 289–375 °C oraligʻidagi 3,61 % massa yoʻqotish qoldiq P–OH guruhlarining polikondensatsiyasiga toʻgʻri keladi va 300 °C dagi issiqlik bilan ishlov berish nazariy toʻliq kondensatsiyaning taxminan 76 % ini taʼminlaganini koʻrsatadi. 627,9 °C dagi keskin endotermik effekt massa oʻzgarishisiz kechadi va NaPO3 ning adabiyotdagi suyuqlanish haroratiga (628 °C) toʻliq mos keladi; bu mahsulotda zanjirsimon polifosfat fazasi hosil boʻlganini tasdiqlaydi. Olingan mahsulot argon muhitida 775 °C gacha termik barqaror.
