Известна ишхта- дл  получени  жаростойкого легкого заполнител , включаюиш  огнеупорную глинл и с,в з1ку вопучиватель.A known ishhta is for obtaining a heat-resistant lightweight aggregate, including your refractory clay and, in the top section.

Цель изобретени  - снизить объемный вес заполнител .The purpose of the invention is to reduce the bulk weight of the filler.

Достигаетс  это тем, что ши.хта содержит в качестве св 13:ки вопучивател  кремнийорганический силикат плотностью 1,30-1,35 npi следующем соотношении компонентов, вес. %: Огнеупорп.а  глина58-62This is achieved by the fact that shi.hta contains, as cf 13: ki vopuchatel organosilicon silicate with a density of 1.30-1.35 npi, the following ratio of components, weight. %: Refractory Clay 58-62

Кремнийорганичеокий силикат плотностью 1,3-1,35 38-42Silicone silicate with a density of 1.3-1.35 38-42

Огнеупорные глины имеют относительно высокую температуру плавлени  1650- 1750° С, а газы удал ютс  в интервале температур 900-1300° С при разложении карбонатов и сульфатов и дегидратации каолинита . Вводимый Кремн;ийорта1Н-ичеокий силикат  вл етс  легкопласкиМ соединен ибм, бла.годар  чему в момент иагтеисивного тазовыделени  ои создает .пиропластическую оболочку, и происходит вспучива ние огнеупорной глины.Refractory clays have a relatively high melting point of 1650-1750 ° C, and gases are removed in the temperature range of 900-1300 ° C with the decomposition of carbonates and sulfates and the dehydration of kaolinite. Silicon-injected ioride 1H-icheic silicate is a light-molded compound, ibm, which is good at the moment of artificial pelvic release and creates a pyroplastic shell, and swelling of refractory clay occurs.

Объемный (вес .полученного за1полнител  зависит от времени выдержки при различных тем перату рах.Volumetric (the weight of the obtained holder depends on the exposure time at different temperatures.

Так, например, при обжиге предварительно сформованных из описываемой шихты (огнеупорна  глина 62%, и кремнийорганический силпкат 38%) во вращающейс  печи длиной 14 .4 и диаметром 2,5 м при температуре 1250°С можло получить легкий заполнитель с объемным весом 370 .и, прочностью при сжатии в цилпндре 11,2 кг1с.ч, огн:еунС|рностью 1500° С и водопоглощеннем при выдержке образцов в течение 1 час- 8, 10%.Thus, for example, when roasting preformed from the described mixture (refractory clay 62% and silicone silpkat 38%) in a rotary kiln 14.44 in length and 2.5 m in diameter at 1250 ° C, a lightweight aggregate with a bulk weight of 370 could be obtained. and, compressive strength in a cylinder of 11.2 kg / hr, fire: 1500 ° C and water absorbed when samples are held for 1 hour, 8, 10%.
