Изобретение относитс к способам непрерывной обработки изделий из стекла или стеклокристаллического материала в солевом расплаве.The invention relates to methods for the continuous processing of glass or glass-ceramic material in a molten salt.
Известен способ упрочнени стекла путем ионного обмена, в котором предварительно нагретью издели погружают в солевой расплав, наход щийс при температуре между точкой напр женности и разм гчени стекла на вре м , необходимое дл замены ионов щелочного металла в стекле на ионы из расплава l .A known method of glass hardening is by ion exchange, in which the preheated product is immersed in a salt melt that is at a temperature between the point of intensity and softening of the glass at the time required to replace the alkali metal ions in the glass with ions from the melt l.
Недостатком его вл етс быстрое обогащение расплава ионами, выход щими с поверхности стекла, что делает расплав непригодным дл дальнейшего использовани .Its disadvantage is the rapid enrichment of the melt with ions emerging from the surface of the glass, which makes the melt unsuitable for further use.
Известны способы, позвол ющие увеличить срок службы солевых расплавов путем добавки к солевому расплаву (нитрат кали ) металлического олова или алюмини 2.Methods are known that allow increasing the service life of salt melts by adding tin metal or aluminum 2 to a salt melt (potassium nitrate).
Несмотр на то, что эти добавки и снижают вли ние загр знений солевых расплавов, тем не менее по истечении определенного времени процесс упрочнени замедл етс .Although these additives reduce the effect of contamination of the salt melts, however, after a certain time, the hardening process slows down.
Наиболее близким вл етс способ упрочнени изделий из стекла путем The closest is a method of strengthening glassware by
обработки в солевом расплаве, в котором в противоположность направлению движени упрочн емых предметов поддерживаетс перепад температур 31,treatment in a salt melt, in which, in contrast to the direction of movement of the hardened objects, a temperature difference of 31 is maintained,
Недостатком его вл етс невысокое качество обработки изделий за счет загр знени солевого расплава токами из стекла. Its disadvantage is the low quality of product processing due to contamination of the molten salt with glass currents.
Целью изобретени вл етс повышение качества обработки изделий.The aim of the invention is to improve the quality of processing products.
Она достигаетс тем, что упрочнение изделий из стекла путем обработки в солевом расплаве осуществл ют в противотоке позонно, причем в каждой зоне поддерживают заданную концентрацию загр знений.It is achieved by hardening glass products by treating in a salt melt in a countercurrent zone, with a predetermined concentration of contaminants being maintained in each zone.
Изобретение по сн етс примером его осуществлени .The invention is illustrated by an example of its implementation.
Предварительно разогретые предметы из стекла, подлежащие упрочнению, проход т через систему из нескольких однородных емкостей с. солевым расплавом , св занных друг с другом.В отдельных емкост х поддерживаетс одинакова или различна температура. Прохождение изделий через отдельные емкости с солевым расплавом производ т при периодическом движении вверх и вниз в каждой емкости с солевым расплавом . Одновременно в систему ввод тPreheated glass objects to be hardened pass through a system of several homogeneous containers. salt melt associated with each other. In separate tanks, the temperature is the same or different. The passage of products through separate tanks with molten salt is produced by periodically moving up and down in each tank with a salt melt. At the same time, the system is entered into
предварительно разогретый солевой расплав противотоком к направлению движенил изделий, при этом концентраци загр знени уменьшаетс от одной зоны расплава к другой по ходу обработки изделий.preheated molten salt countercurrent to the direction of movement of products, while the concentration of contamination decreases from one zone of the melt to another during the processing of products.
