Description
Известны способы измерени скорости пленкообразовани на нодложке , основанные на определении изменени твердости иленки ма тниковым прибором или на определении содержани нерастворимого полимера в ней весовыми приборами.Methods are known for measuring the speed of film formation on a substrate, based on the determination of the change in the hardness of a film with an attendant device or on the determination of the content of insoluble polymer in it by weight devices.
Однако эти способы не позвол ют непрерывно измер ть скорость пленкообразовани .However, these methods do not allow continuous measurement of the rate of film formation.
Предложен способ непрерывного определени скорости п.ченкообразовани путем измерени теплоты, выдел ющейс в процессе пленкообразовани .A method has been proposed for continuously determining the speed of forming formations by measuring the heat released in the process of film formation.
По предложенному способу исследуемый материал нанос т на реакционную подложку, помещенную в сосуд типа Дьюара, вакуумированный или газонаполненный, который расположен в воздущном термостате (один из вариантов адиабатического колориметра). Измерение теплоты , выдел ющейс в ходе реакции, производ т термопарой, рабочий спай которой помещен в специальный карман реакционной подложки.According to the proposed method, the material under study is applied to a reaction substrate placed in a Dewar type vessel, evacuated or gas-filled, which is located in an air thermostat (one of the variants of an adiabatic colorimeter). The heat released during the reaction is measured by a thermocouple, the working junction of which is placed in a special pocket of the reaction substrate.
На чертеже изображена схема устройства дл осуществлени предлагаемого способа.The drawing shows a diagram of an apparatus for carrying out the proposed method.
Реакционна подложка 1 представл ет собой круглую металлическую пластину с карманом 2 дл термопары 3- Во избежание слива наносимого на подложку жидкого вещества она снабжена бортиком 4. Иодложка крепитс винтом 5 на полом эбонитовом держателе 6, надетом на стекл нную трубку 7 со щлифом 8. При проведении опыта реакционную подложку помещают в сферический сосуд 9 типа Дьюара, дл чего шлиф 8 вставл ют в тубус Ю. Тубус // этого сосуда закрыт щлиThe reaction substrate 1 is a circular metal plate with a pocket 2 for thermocouple 3-. conducting the experiment, the reaction substrate is placed in a spherical Dewar type vessel 9, for which section 8 is inserted into the tube Y. Tube // of this vessel is closed
