Description
Пример 3. Компоненты св зки: этилсиликат (85%), воду (12%), этиловый спирт (27о) и сол иую кислоту (1%) охлаждают в отдельности до 10°С. В гидролизующую среду (смесь воды и этилового спирта) ввод т сначала кислоту, а затем этилсиликат и перемешивают 40 мин.Example 3. Binding components: ethyl silicate (85%), water (12%), ethyl alcohol (27 °) and hydrochloric acid (1%) are cooled separately to 10 ° C. Acid is introduced into the hydrolyzing medium (a mixture of water and ethyl alcohol), and then ethyl silicate is mixed for 40 minutes.
Пример 4. Компоиенты св зки: этилсиликат (88%), воду (11,3%), сол ную кислоту (0,5%) охлаждают в отдельности до 16°С. В смесь воды и кислоты ввод т этилсиликат и, перемешива , гидролизуют его в- течение 40 мин.Example 4. Binding compounds: ethyl silicate (88%), water (11.3%), hydrochloric acid (0.5%) are cooled separately to 16 ° C. Ethyl silicate is added to a mixture of water and acid and, after mixing, it is hydrolyzed within 40 minutes.
Пример 5. Состав св зки и технологи ее приготовлени , как в примере 4, но перед с.мешением компоненты охлаждают до 19°С.Example 5. The composition of the binder and its preparation technology, as in Example 4, but before sintering, the components are cooled to 19 ° C.
На св зках, приготовленных согласно примерам 1-5, изготовлены образцы корундовых огнеупоров.Samples of corundum refractories were made on the bonds prepared according to examples 1-5.
Свойства этилсиликатного св зуюш;его, приготовлеиного согласно примерам 1-5, а также свойства корундовых огнеупоров на основе этого св зуюпдего приведены в таблице.Properties of ethyl silicate binder; its prepared according to examples 1-5, as well as the properties of corundum refractories based on this bond are listed in the table.
Таким образом, св зующее, полученное согласно изобретению, не расслаиваетс , т. е. гомогенно, и материалы, полученные на основе этого св зуюш,его, обладают повышенной прочностью.Thus, the binder obtained according to the invention does not delaminate, i.e., is homogeneous, and the materials obtained on the basis of this binder, it, have increased strength.
