Poliakrilonitril matosining olovga chidamliligini oshirish maqsadida u dastlab karbamid bilan modifikatsiya qilindi.
So‘ngra, modifikatsiyalangan poliakrilonitril matoni ortofosfat kislotasi bilan qayta kimyoviy ishlov berildi va natijada olovbardosh PAN matosi sintez qilindi. Sintes qilingan N va P tutgan yong‘inga chidamli poliakrilonitril materialining tarkibi va yonish darajasi Furye infraqizil spektroskopiyasi, rentgenofazaviy tahlili va cheklovchi kislorod ko‘rsatkichi yordamida o‘rganildi. Yong‘inga chidamli poliakrilonitril matoning cheklovchi kislorod ko‘rsatkichi qiymati 20 marta yuvish davridan so‘ng 28,5% ni tashkil etdi, bu esa yuvilishga bardoshliligidan va yong‘inga chidamliligidan dalolat beradi.

Для повышения огнестойкости полиакрилонитрильной ткани ее изначально модифицировали мочевиной. Затем модифицированную полиакрилонитрильную ткань обработали ортофосфорной кислотой, в результате был получен трудногорючийматериал из ПАН. Состав трудногорючего модифицированного N и P содержащего полиакрилонитрильного материала исследовали методами инфракрасной Фурье- спектроскопии, рентгенофазового анализа, а скорость горения определена изучением предельного кислородного индекса. Значение предельного кислородного индекса модифицированных полиакрилонитриловых тканей составило 28,5% после 20 циклов стирки, что свидетельствует о ее стойкости к стирке и огнестойкости.

English

In order to increase the fire resistance of polyacrylonitrile fabric, it was originally modified with urea. The modified polyacrylonitrile fabric was then chemically treated with orthophosphate acid, resulting in the synthesis of a flammable PAN fabric. The composition and combustion rate of the refractory polyacrylonitrile material containing the synthesized N and P were studied using Fourier infrared spectroscopy, X-ray phase analysis, and limited oxygen index.
The limited oxygen index value of fire-resistant polyacrylonitrile fabric was 28.5% after 20 wash cycles, which indicates its washing resistance and fire resistance.
