Description

Известный способ стабилизации кристаллической структуры ориентированной пленки из полиэтилентерефталата путем термофикации, заключающийс  в прогреве раст нутой пленки при достаточно высокой температуре, требует громоздкого дорогосто щего оборудовани , а длительность процесса увеличиваетс .The known method of stabilizing the crystal structure of an oriented polyethylene terephthalate film by thermification, which consists in heating the stretched film at a sufficiently high temperature, requires bulky, expensive equipment, and the process time increases.

По предложенному способу стабилизаци  структуры пленки производитс  погружением ее в ацетон на 3-5 мин при комнатной температуре , что удешевл ет и ускор ет процесс стабилизации.According to the proposed method, the stabilization of the film structure is performed by immersing it in acetone for 3-5 minutes at room temperature, which reduces the cost and speeds up the stabilization process.

Зл  осуществлени  предложенного способа стабилизации кристаллической структуры ориентированной пленки из полиэтилентерефталата пленка подвергаетс  плоскостной выт жке (4x4 раза) при температуре 100° и скорости раст жени  12,4 мм/сек. Затем производитс  погружение в ацетон на 3-5 мин при комнатной температуре.Due to the proposed method of stabilizing the crystal structure of an oriented polyethylene terephthalate film, the film is subjected to a planar stretch (4x4 times) at a temperature of 100 ° and a stretching rate of 12.4 mm / sec. It is then immersed in acetone for 3-5 minutes at room temperature.

Обработка пленки предложенным способом позвол ет гоаавно регулировать тонкие изменени  структуры и получать издели  с различными свойствами. Возможность получени  изделий с различными свойствами заключаетс  в варьировании температуры пластификатора (ацетона или др.), что позвол ет измен ть интенсивность его пластифицирующего действи , а также примен ть смеси различного соотнощени  -пластификатора с инертным (по отношению к данному полимеру) веществом.The processing of the film by the proposed method makes it possible to regulate subtle changes in the structure and to obtain products with different properties. The possibility of obtaining products with different properties consists in varying the temperature of the plasticizer (acetone or others), which allows varying the intensity of its plasticizing effect, as well as using mixtures of different plasticizer ratios with an inert (with respect to this polymer) substance.

Предложенный способ позвол ет тонко регулировать строение и свойства получаемого издели  и дает возможность обрабатывать пленку в вертикальном положении.The proposed method allows fine adjustment of the structure and properties of the resulting product and makes it possible to process the film in a vertical position.

№ 149565- 2 Предмет изобретени No. 149565- 2 The subject invention
