Description

Изобретение относитс  к области сварки пластмасс, а именно к способам сварки термопластичных полимерных пленок излучением.
Цель изобретени  - повышение качества сварного соединени .
Ка фиг. 1 изображена схема реализации способа; на фиг. 2 - расположение свариваемых пленок после нагрева светопоглощающего сло  до в зкотекучего состо ни } на фиг. 3 - то же, после нагрева сло  до температуры сварки; на фиг. 4 - распределение температуры по сечению пленок после нагрева сло  до в зко- текучего состо ни ; на фиг. 5 - то же, после нагрева сло  до температуры сварки. .
Способ сварки излучением термопластичных полимерных пленок заключаетс  в следующем.
Соедин ют термопластичные пленки 1 и 2, прозрачные дл  оптического излучени . На соедин емую поверхность 3 пленки 2 нанос т тонкий све- топоглощающий слой 4, сформированный, например, внедрением черного красител  в материал пленки. Включают т нущие ролики 5 и 6 транспортирующего механизма не показан) и нагреватели 7 и 8. Устанавливают такой режим работы нагревател  7, при котором светопоглощающий слой 4 переходит в в зкотекучее состо ние. Нагревают излучением слой 4 до в зкотекучего состо ни , при этом па счет

теплопрс водности переходит в в зко- текучее состо ние и тонкий слой прозрачного материала пленки 2, непосредственно примыкающий к светопогло- дающему слою 4 .
На первом этапе нагрева пленки 1 и 2 не прижаты друг к другу (они могут быть вообще разведены) и между ними нет плотного механического и Ю теплового контакта (фиг. 2). Основной материал обеих пленок ввиду его i прозрачности дл  излучени  остаетс  практически при комнатной температуре (фиг. 4), на которой лини  9 со- 15 ответствует комнатной температуре, а лини  10 - температуре плавлени  материала. После нагрева сло  до в зкотекучего состо ни  пленки проход т через прижимные ролики 11 20 и 12, в результате чего происходит сближение соедин емых поверхностей 3 и 13 пленок 1 и 2 и сдавливание их, причем разогрета  поверхность 3 повтор ет форму поверхности 13. 25 Образуетс  гшотный механический и теплово контакт этих поверхностей (фиг. 3). При сдавливании пленок передавливани  шва не происходит вследствие локального характера разо- 30 грева пленки 2.
При поступлении пленок 1 и 2 в зону действи  нагревател  8 происходит нагрев излучением светопоглощаю- щего сло  1 до оптимальной темпера- -. туры сварки (фиг. 5) с симметричным расплавлением прилегаюгцих к нему прозрачных материалов пленок 1 и 2 и образованием общей ;1л  обеих пленок зоны переплава. При дальнейшем осты- .« ванн этой зоны образуетс  сварное соединение.
Пример. Установка дл  осуществлени  способа имеет следуюШ51е технические характеристики. Макси
мальна  мощно ть нагревателей 500 Вт Нагреватели представл ют собой трубчатые кварцевые лампы накалива,- ни  типа КГ 110-500-1, снабженные рефлекторами. Нити канала ламп ори- ентированы вдоль линии щва. Пределы регулировани  мощности нагревателей составл ют 30-100%. Скорость прот жки материалов (скорс сть снарки)

Свариваемыми образпами  вл ютс  пленки из поливинилхлорида толщиной 0,2 мм. Температуры плавлени  и термической деструкции материалов со- . ставл ют соответственно 160 и 250- .
Соедин ема  поверхность 3 пленки 2 зачернена путем введени  красител  на г лубину до 0,01 мм. Ширина зоны зачернени , определ юща  ширину шва, равна 5 мм. Подобранна  концент- pairHH красител  обеспечивает поглощение не менее 95% падающей световой энергии li области д;и1н BOJUI 0,4- 3,5 мкм.
Устанавливают мощность нагревателей 7 и 8 соответственно 400 и 500 Вт. Включают транспортирующий механизм, отро улированньп на скорость сварки 4 м/мин. Зачерненный контактный сло11 пленки 2 под вотпействием излу чени  нагревател  7 переходит в в з- котекучее состо ние (нагреваетс  до 170 С). В резулыате прохождени  пленок через прижимные ролики 5 и 6 происходит их соединение с приложением давлени . Усилие прижима равно 1,0 кгс. Вторич)1ый нагрев светопогло- щающего сло  происходит под воздействием излучени  нагревател  8 без приложени  давлени  нл соедин емые пленки.
