Abstract

Цей винахід дозволяє прогнозувати вміст компонентів у процесі полімеризації араміду, використовуючи метод спектроскопії в діапазоні, близькому до діапазону інфрачервоного випромінювання, при довжині хвиль випромінювання 600 ... 2500 нм, зокрема 1100 ... 2500 нм. Спосіб, що пропонується, полягає в тому, що визначають кореляцію між вмістом компонентів у зразках з відомим складом компонентів, і спектром цих зразків у діапазоні, близькому до діапазону інфрачервоного випромінювання, використовують одержані дані про кореляцію для створення розрахункової формули, необхідної для прогнозування, підтверджують точність розрахункової формули, використовуючи для цього еталонні зразки, і використовують підтверджену розрахункову формулу для визначення вмісту компонентів у невідомих зразках. Поглинення випромінювання визначають за допомогою методу вимірювання абсолютного поглинення, першої, другої, третьої, четвертої або вищої похідної поглинення або за допомогою інших методів обробки сигналів. Сигнали, що характеризують вміст компонентів, можуть використовуватися для управління технологічним процесом виробництва продуктів з багатьма компонентами за допомогою елементів технологічного обладнання, які справляють визначений вплив на компоненти, вміст яких регулюється.
