Изобретение относитс  к технологии производства изделий из кварцевого стекла и может быть использовано при изготовлении химической посуды и приборов.;The invention relates to the production technology of quartz glass products and can be used in the manufacture of chemical glassware and appliances .;

Цель изобретени  - .повышение качества соединени  издел йй кварцевого стекла. The purpose of the invention is to improve the quality of the compound of quartz glass products.

В предлагаемом сйособе на соедин емые поверхности изделий из кварцевого стекла нанос т слой порошка окиси свинца, состыковьшают заготовки и прогревают при 890-920 С. Образовавшийс  стеклообразньй слой обладает хорошей адгезией по отношению к кварцевому стеклу, поскольку дву : окись кремни  входит в его состав, а при затвердевании приобретает боль Шую механическую прочность.In the proposed technique, a layer of lead oxide powder is applied to the joined surfaces of quartz glass products, the blanks are joined and heated at 890-920 C. The resulting glassy layer has good adhesion to quartz glass, since two: silicon oxide is part of it, and when hardening, it becomes painfully mechanical.

За счет того, что процесс соединени  изделий ведут при температурах , которые значительно ниже температуры разм гчени  кварцевого стекла (), сохран етс  геометрическа  форма и размеры соедин емых изделий, что значительно улучшает качество изготовл емых изделий.Due to the fact that the process of joining products is carried out at temperatures that are significantly lower than the softening temperature of quartz glass (), the geometric shape and dimensions of the connected products are preserved, which significantly improves the quality of the manufactured products.

Пример. Провод т соединение двух трубок из кварцевого стекла внешним диаметром 28 мм и толщиной стенки 2 мм. Торцы соедин емых трубок сошлифовьшают с помощью корундового порошка марки М 28, после .чего на сошлифованный торец однойExample. Two quartz glass tubes with an outer diameter of 28 mm and a wall thickness of 2 mm are connected. The ends of the connected tubes are ground with the help of corundum powder of mark M 28, after that on the ground end of one

из трубок нанос т порошок окиси свинца (II), трубки состыковывают, место стыка прогревают с помощью печи сопротивлени  до 890°С и выJ держивают при этой температуре в течение 1,5 ч, после чего охлаждают изделие до комнатной температуры. Полученное изделие по геометрическим размерам соответствует размерам за-Lead (II) oxide powder is applied from the tubes, the tubes are joined, the junction is heated with a resistance furnace to 890 ° C and held at this temperature for 1.5 hours, after which the product is cooled to room temperature. The resulting product in geometric dimensions corresponds to the size of the

to готовок,, деформаци  не произошла, стык прозрачный, однородный, стенки трубок также прозрачны.To prepare, the deformation did not occur, the joint is transparent, uniform, the walls of the tubes are also transparent.

П р и м е . Провод т соединение двух трубок аналогично примеруPRI m e. Connect the two tubes in the same way as

Нарушени  геометрических размеров заготовок не наблюдаетс , стенки трубок прозрачны, стык прозрачный, однород-t5 1, however, the shutter speed of the junction is adjusted for I h. There is no violation of the geometrical dimensions of the blanks, the walls of the tubes are transparent, the junction is transparent, uniform

Приме р 3. Соединение заготовок провод т аналогично примеру 1. Место стыка выдерживают при 920 С в течение } ч. Образовалось прочное соединение, шов прозрачен, нарушени  геометрических размеров заготовок нет.Example 3. The connection of the workpieces is carried out analogously to example 1. The joint is kept at 920 ° C for} h. A strong connection was formed, the seam is transparent, there is no violation of the geometric dimensions of the workpieces.

П р и м е р 4. Процесс ведут аналогично примеру 1. Вьщержку стыка осуществл ют при 920С в течение 1,5 ч. Образовалось прочное соединение , шов прозрачен, нарушени  геометрических размеров и ухудшени  прозрачности заготовок не наблюдаетс .EXAMPLE 4 The process is carried out analogously to example 1. The butt splice is carried out at 920 ° C for 1.5 hours. A strong joint was formed, the seam is transparent, the geometric dimensions are not observed and the transparency of the blanks is not deteriorated.
