Abstract
Изобретение относитс к огнеупорным материалам и может быть использовано в качестве футеровки стеклоплавильных аппаратов. Цель изобретени - снижение пористости и температурной усадки бетона после нагревани до 1000°С. Огнеупорный бетон содержит, мас.% : высокоглиноземистый цемент 10-21, огнеупорна глина 13-19, полимеризованна фенолформальдегидна смола 2-4, шамотный заполнитель - остальное. Бетон характеризуетс после нагревани до 1000°С температурной усадкой 0,14-0,22%, открытой пористостью 12-19%. 2 табл.The invention relates to refractory materials and can be used as a lining for glass melting apparatuses. The purpose of the invention is to reduce the porosity and temperature shrinkage of concrete after heating to 1000 ° C. The refractory concrete contains, in wt.%: High-alumina cement 10-21, refractory clay 13-19, polymerized phenol-formaldehyde resin 2-4, fireclay filler - the rest. Concrete is characterized after heating to 1000 ° C with a temperature shrinkage of 0.14-0.22%, an open porosity of 12-19%. 2 tab.
Description
Изобретение относитс к огнеупорной промьшшенности и может быть использовано в качестве футеровки стеклоплавильных аппаратов.FIELD OF THE INVENTION The invention relates to refractory industry and can be used as a lining for glass-smelting apparatuses.
Цель изобретени - снижение пористости и температурной усадки бетона после нагревани до 1000 С.The purpose of the invention is to reduce the porosity and temperature shrinkage of the concrete after heating to 1000 C.
Составы огнеупорного бетона приведены в табл, 1 .The compositions of refractory concrete are given in table. 1.
Характеристики огнеупорного бетона после нагревани до 1000 С приведены в табл.2.The characteristics of refractory concrete after heating to 1000 ° C are given in Table 2.
При сравнении свойств известного и предлагаемого огнеупорных бетонов после нагревани до открыта пористость снижаетс на 12-19%, температурна усадка уменьшаетс в,5- 6 раз.When comparing the properties of the known and proposed refractory concretes after heating to the open, the porosity decreases by 12-19%, the temperature shrinkage decreases by a factor of 5-6.
