Description
которые разлагаютс при температурах более высоких, чем температура термообработки изделий. усиливаетс при применении микродобавок свежеосакденного гидрата окиси железа Ре(ОИ)э , что Позвол ет интенсифицировать термообработки и тем самым упростить технологию изготовлени теплоизол ционных изделий . Пример 1. В растворомешалке готов т массу следующего состава, масс.%: перлит вспученный 64,5; трепел 10; фосфатное в жущее 15; Fe(OH 0,5; вода 10. Вначале, в течение 90-120 с перемешивают сухие компо .иенты, затем добавл ют воду,.кислоту и перемешивают еще 120 с, после чего массу прессуют в формах под давлением О,3 МПа или формуют методом вибрировани с пригрузом и подвергают термообработке -при 500С. Пример 2. Готов т мас.су следующего состава, масс.%; перлит вспученный 43,5; трепел 15; фосфатное в жущее 25; вода 15; РеСОН) 1,5. Технологи приготовлени и применени массы аналогична примеру 1. Пример 3. Готов т массу следующего состава, масс.%: перлит вспученный 55; трепел 12; фосфатное в жущее 20; вода 12, FeCOH) 1,0. Технологи приготовлени и применени масбы аналогична примеру 1. В таблице приведены физико- мехаиические показатели бетона, полученного из предлагаемых составов сырьевой смеси, а также из известной сырьевой смеси.which decompose at temperatures higher than the heat treatment temperature of the products. increases with the use of microadditives of freshly hydroxide iron oxide Fe (OI) e, which makes it possible to intensify heat treatments and thereby simplify the technology for the manufacture of heat insulating products. Example 1. In a mortar mixer, a mass of the following composition is prepared, wt.%: Expanded perlite 64.5; Tripoli 10; Phosphate Subsidium 15; Fe (OH 0.5; water 10. At first, for 90-120 s, dry components are mixed, then water and acid are added and mixed for another 120 s, after which the mass is pressed into molds at a pressure of 0 MPa or molded using the vibrating method with the weights and subjected to heat treatment at 500 C. Example 2. Prepare a bulk composition of the following composition, wt.%; expanded perlite 43.5; tripilla 15; phosphate based 25; water 15; The technology of preparation and use of the mass is similar to Example 1. Example 3. A mass of the following composition is prepared, wt.%: Expanded perlite 55; Tripoli 12; phosphate in a per 20; water 12, FeCOH) 1.0. The technology of preparation and application of masses is analogous to example 1. The table shows the physicomechanical parameters of the concrete obtained from the proposed composition of the raw mix, as well as from the known raw mix.
