Изобретение относитс к области вакуумноплотного сочленени деталей стеклооболочки цветного кинескопа.The invention relates to the field of vacuum-tight articulation of parts of the glass shell of a color kinescope.
Известный способ вакуумноплотного сочленени деталей электровакуумных приборов состоит в том, что на сопр гающиес поверхности нанос т слой суспензии порошка легкоплавкого стекла в органическом растворителе , сушат их 2 час на воздухе, затем откачивают объем до давлени пор дка 25 мм рт. ст., после чего нагревают изделие в течение 10 мин при температуре, превышающей температуру отжига на 140°С. Однако, когда стекло находитс в расплавленном состо нии, сочлен емые детали могут перемещатьс относительно друг друга, что недопустимо нри этом процессе , требующем большой точности взаимного расположени деталей.A known method of vacuum-tight articulation of parts of electrovacuum devices consists in applying a layer of a suspension of powder of low-melting glass in an organic solvent to the mating surfaces, drying them for 2 hours in air, then pumping out the volume to a pressure of about 25 mm Hg. Art., after which the product is heated for 10 minutes at a temperature exceeding the annealing temperature by 140 ° C. However, when the glass is in the molten state, the parts to be joined may move relative to each other, which is unacceptable during this process, which requires great precision in the relative position of the parts.
Предлагаемый способ отличаетс от известного тем, что перед нанесением герметизирующего вещества производ т механическое скрепление деталей при помощи кле низкотемнературного отвердевани , а затем герметизирующее вещество, например легкоплавкую эмаль или кристаллизующийс стеклоцемент , нанос т на боковые поверхности сопр гаемых деталей с последующим отжигом.The proposed method differs from the well-known fact that before applying a sealing substance, the parts are mechanically bonded using low-temperature hardening glue, and then the sealing substance, such as low-melting enamel or crystallized glass cement, is applied to the lateral surfaces of the adjacent parts with subsequent annealing.
Это позвол ет упростить технологию процесса и повысить точность сборки деталей (точность их взаимного расположени ), например , при сочленении экрана с рамой, на которой закреплена фокуспрующа сетка. Допуск на изменение относительного расположени соедин емых деталей не превышает 5- 10 мкм.This makes it possible to simplify the process technology and improve the accuracy of the assembly of parts (the accuracy of their relative position), for example, when the screen is joined to the frame on which the focusing grid is fixed. The tolerance for changing the relative position of the connected parts does not exceed 5-10 microns.
