Изобретение относитс к получению натрий-кальциевого силиката и мо жат быть использовано дл варки оптических стекол специального назначени .The invention relates to the preparation of sodium-calcium silicate and can be used for cooking optical glasses for special purposes.
Известен способ получени натрийкальциевого силиката, используемого при варке стекла, включающий взаимодействие метасиликата натри , метасиликата кальци и кремнезема гидротермалыалм способом в автоклаве с последующей фильтрацией осгщка и его сушкой fl и .A method of producing sodium calcium silicate used in glass melting is known, including the interaction of sodium metasilicate, calcium metasilicate and silica by hydrothermal metal in an autoclave, followed by filtration by drying and fl.
Недостатком известного способа вл етс низка степень чистоты целевого продукта и сложность технологического процесса.The disadvantage of this method is the low purity of the target product and the complexity of the process.
Цель изобретени - упрощение процесса и повышение степени чистоты целевого продукта.The purpose of the invention is to simplify the process and increase the purity of the target product.
Поставленна цель достигаетс тем, что взаимодействию подвергаю раствор силиката натри и гидросиликата кальци состава CaO«3S10 y 4Нор, причем его осуществл ют при 70-95 С в течение 1-2 ч.This goal is achieved by exposing the interaction to a solution of sodium silicate and calcium hydrosilicate of the composition CaO 3S10 y 4Nor, and it is carried out at 70-95 ° C for 1-2 hours.
Силикат формулы СаО 3S i О- получают по известному способу.The silicate of the formula Cao 3S i O- is obtained by a known method.
Способ осуществл ют следующим образом.The method is carried out as follows.
Раствор силиката натри и гидц осиликата кальци состава.СаО- ,jX 4НлО cMQiMBawT в реакторе в течение 1-2 ч. Затем полученна суспензи подвергаетс сушке при 200-220°С до содержани влаги в целевом продукте 2-4 масс.%..A solution of sodium silicate and the hydrots calcium calcium silicate composition. CaO-, jX 4HLO cMQiMBawT in the reactor for 1-2 hours. Then, the resulting suspension is dried at 200-220 ° C to a moisture content of the target product 2-4 wt.%
П р и м е р. Дпй получени 1 кг натрий-кальциевого силикат9 (компо0 зиции) в реакционн&й сосуд с мещал- кой загружаю 6,55 л раствора силиката натри ,/Naap 3,0 (концентраци - 30 г/л, 51Од 90 г/л) и при непрерывном пер меши- вании добавл ют 275 г СаОЗ -Юа PRI me R. In order to obtain 1 kg of sodium-calcium silicate9 (composition), I load 6.55 l of sodium silicate solution, / Naap 3.0 (concentration 30 g / l, 51 Od 90 g / l) into a reaction vessel with a broomstick and with continuous mixing, 275 g of CaO3 -Ua are added.
