Термохромна  пленка изготавливаетс  путем смешени  эмульсии производных холестерина в коллоидном растворе поливинилового спирта при введении 2,2,6,6тетраметил-4-оксипиперидина с последуюш ,им отливом коллоида на гладкую полированную поверхность.A thermochromic film is made by mixing an emulsion of cholesterol derivatives in a colloidal solution of polyvinyl alcohol with the introduction of 2,2,6,6 tetramethyl-4-hydroxypiperidine followed by casting a colloid on a smooth, polished surface.

Определение температуры производитс  путем визуального наблюдени  за изменением цвета прикрепленной к исследуемой поверхности пленки.The temperature determination is made by visual observation of the color change of the film attached to the test surface.

Оптимальна  добавка 2,2,6,6-тетраметил4-оксипиперидина составила 0,9 вес. %. Дальнейшее увеличение количества 2,2,6,6тетраметил-4-оксипиперидина приводит к снижению контрастности цветового перехода термохромной пленки, а уменьшениеThe optimal addition of 2,2,6,6-tetramethyl4-hydroxypiperidine was 0.9 weight. % A further increase in the amount of 2,2,6,6 tetramethyl-4-hydroxypiperidine leads to a decrease in the contrast of the color transition of the thermochromic film, and a decrease in

его количества - к умеНьШёнию срока службы термохромной пленки.its amount is to improve the life of the thermochromic film.

Применение предлагаемых термохромных пленок помимо увеличени  надежности и долговечности их позволит упростить тепловой контроль в динамике без дорогосто ш ,ей аппаратуры.The application of the proposed thermochromic films in addition to increasing their reliability and durability will make it possible to simplify thermal control in dynamics without expensive equipment.
