Description
Изобретение относитс к способам приготовлени фосфатного в жущего типа порошок-оксида-кислота и может быть использовано при применении эт композиций в качестве неорганически клеев в радиоэлектронике, электротехнике , при приготовлении абразивн инструментов. fИзвестенспособ приготовлени фосфатного в жущего путем обжига сырьевой шихты с последующим затвор нис:: пртрфосфорной кислотой 1 5. Наиболее близким по технической сущности и достигаемому эффекту к изобретеиию вл етс способ Приготовлени фосфатного в жущего пуг«м обжига сьфьевой шихты с полупроводниковым оксидом при температуре 1рОО-1200 С с последующим затворени ем ортофосфорной кислотой L23. Недостатками такого способа вл ютс веобходим9сть обжига сырьевой ошхты при высоких температурах и сложность технологических операций. Целью изобретени вл етс упрощение технологии приготовлени в жущего. Поставленна цель достигаетс тем, что согласно способу приготовле ш фосфатного в жущего путем затворени порошка-оксида ортофосфориой кислотой предварительно порошок оксида меди смешивают с карбидом кремни в количестве 1-4% от массы оксида меди. Пример. Оксид меди смешивают с полупроводниковым веществом алмазо-т подобной структуры - карбидом кремни (Sic). Порошки полупроводниковых веществ с алмазоподобной структурой имеют удельную поверхность 3000-3500 , количество их соответствует 1-4% от массы оксида. Полученна смесь затвор етс ортофосфорной кислотой 85%-ной концентрации при соотношении ,24. Полученные результаты приведены в таблице. Экономи vческий эффект от применени предлагаемого способа составл ет ,.от стоимости на единицу продукции по сравнению с известным.The invention relates to methods for the preparation of a phosphate solid type powder-oxide-acid and can be used when using these compositions as inorganic adhesives in radio electronics, electrical engineering, in the preparation of abrasive tools. fThe well-known method of preparation of phosphate as a binder by burning the raw material charge followed by a gate of the acid: prthophosphoric acid 1 5. The most similar in technical essence and effect to the invention to the invention is the method of preparation of the phosphate binder with a semiconductor oxide layer and a semiconductor oxide layer. 1200 C followed by mixing with orthophosphoric acid L23. The disadvantages of this method are the need to burn the raw material ash at high temperatures and the complexity of technological operations. The aim of the invention is to simplify the preparation of the to-do method. This goal is achieved by the fact that according to the method of preparing phosphate to a binder by mixing powder-oxide orthophosphoric acid, pre-copper oxide powder is mixed with silicon carbide in an amount of 1-4% by weight of copper oxide. Example. Copper oxide is mixed with a semiconductor substance diamond-t of a similar structure - silicon carbide (Sic). Powders of semiconductor substances with a diamond-like structure have a specific surface of 3000-3500, their number corresponds to 1-4% by weight of oxide. The resulting mixture is filled with orthophosphoric acid of 85% concentration at a ratio of, 24. The results are shown in the table. The economic effect of the application of the proposed method is the cost per unit of production compared to the known.
