Description
Изобретение относитс к производ ству химических волокон. Известен способ контрол процесса формовани нитей из расплава пол мера путем периодического измерени режимных параметров процесса i. Недостаток этого способа - низка эффективность, обусловленна бол шой трудоемкостью из-за необходимости одновременно контролировать бол шое количество технологических пара метров . Цель изобретени - повышение эффективности контрол . Это достигаетс тем,что по предлагаемому рпособу определ ют знаки отклонени нат жени и температуры нити от их допустимых значений и при одинаковых знаках отклонений контролируют в зкость расплава полимера, скорость формовани , толщину нити и количество низкомолекул рных соединений (НМС) в формуемой нити, а при разных знаках отклонений - температу ру расплава полимера и скорость обдувочного воздуха.

Измер ют температуру нити датчиком температуры 6 и нат жение нитидатчиком нат жени нити 9. Технические средства измерени - тёрмосопро-. тивление типа ТСМ или иглообразна термопара и измеритель нат жени нити типа ИНН-1. Определ ют знаки отклонени измеренных величин от их установленных допустимых значений. Эту операцию может выполн ть оператор . При одинаковых знаках отклонений (положительных или отрицательных) контролируют в зкость расплава полимера , скорость формовани , ТО.ПЩИНУThe invention relates to the manufacture of chemical fibers. There is a method for controlling the process of forming filaments from a melt of a floor by periodically measuring the operational parameters of process i. The disadvantage of this method is low efficiency, due to the large labor intensity due to the need to simultaneously control a large number of process parameters. The purpose of the invention is to increase the efficiency of control. This is achieved by the fact that according to the proposed method, the signs of deviation of the tension and the temperature of the thread from their allowable values are determined, and with the same signs of deviations, the viscosity of the polymer melt, the molding rate, the thickness of the thread and the amount of low molecular weight compounds (NMC) in the thread being formed are controlled, and with different signs of deviations — the polymer melt temperature and the speed of the blowing air. FIG. 1 shows a device for carrying out the proposed method, where 1 is a spinning unit; 2 melt temperature sensor; 3 die; 4 - thread) 5 - air temperature sensor; 6 - thread temperature sensor; 7 - dissecting washer; 8 - spindle disc; 9 - tension sensor; 10 - pack / 11 - friction; in fig. 2-7 are graphs of the tension and temperature of the filament on the viscosity and temperature of the polymer melt, the molding speed and speed, blowing air, the thickness of the filament and the number of NMC in the filament. The method is carried out as follows. The temperature of the filament is measured by a temperature sensor 6 and the tension of the filament of a filament by a nitidator 9. Measuring equipment - thermoscopic. TCM or needle-shaped thermocouple and tension meter of the INN-1 type thread. The signs of deviation of the measured values from their stated acceptable values are determined. This operation can be performed by an operator. With the same signs of deviations (positive or negative), the viscosity of the polymer melt, the rate of molding, and the flow temperature are monitored.
