Изобретение относитс к составам дл изготовлени стеновых материалов, используемых в строительстве.The invention relates to compositions for the manufacture of wall materials used in construction.
Целью изобретени вл етс сокращение продолжительности термообработки при сохранении качества.The aim of the invention is to reduce the duration of heat treatment while maintaining quality.
Технологи изготовлени стенового материала заключаетс в следующем.The technology for making wall material is as follows.
Просушенные сыпучие компоненты просеиваютс через сито с величиной отверстий 0,25 мм и перемешиваютс до получени однородной смеси. Затем в смесь заливают жидкое стекло и перемешивают до получени полусухой смеси. Полученную смесь засыпают в разборную форму и прессуют с удельным давлением 2 МПа. После прессовки форму разбирают и блок-сырец подают в печь с температурой 155°С. В течение 1 ч температуру поднимают до 250°С, а затем в зависимости от пустотности блока выдерживают при этой температуре в течение 1-3 ч. По истечении этого времени процесс термообработки прекращают, блок вынос т из печи и оставл ют остывать на воздухе.The dried bulk components are sifted through a 0.25 mm sieve and mixed until a homogeneous mixture is obtained. Then pour liquid glass into the mixture and mix until a semi-dry mixture is obtained. The resulting mixture is poured into a folding form and pressed with a specific pressure of 2 MPa. After pressing, the mold is disassembled and the raw block is fed to the oven with a temperature of 155 ° C. The temperature is raised to 250 ° C for 1 hour and then, depending on the voidness of the unit, it is kept at this temperature for 1-3 hours. After this time, the heat treatment process is stopped, the unit is taken out of the furnace and allowed to cool in air.
Составы стенового материала приведены в табл. 1.The compositions of the wall material are given in table. one.
Физико-механические показатели изделий приведены в табл.2.Physico-mechanical properties of the products are given in table 2.
