Description
Предлагаемые в жущие на основе известных исходных шихт (например , портланд-цементной, известково-зольной ) и гипса отличаютс соотношением коМ|Понентов и температурой обжига. В жущие по предлагаемому способу получаютс следующнм образом.Offered on the basis of known baseline charges (for example, Portland cement, lime-ash) and gypsum are distinguished by the ratio of coM | Ponents and roasting temperature. Stubbing on the proposed method are as follows.
В качестве исходных материалов можно примен ть следующие, тонко измельчённые смеси: 1) известн к , глина и сырой гипс, 2) мергель и сырой гинс, 3) известн к, зола и сырой гипс, 4) известн к, зола и отходы сероочистки дымовых газов по известковому способу - известкоБО-зольный щламм. Соотношение компонентов подбирают в такой пропорции, чтобы в готовом продукте содержание СаО было доведено до 45-50%, а содержание ЗОз -до 8-12%. Смесь обжигаетс в печах при температуре 1150-1250° и после обжига тонко измельчаетс .The following raw materials can be used as raw materials: 1) limestone, clay and raw gypsum, 2) marl and raw horsefish, 3) limestone, ash and raw gypsum, 4) limestone, ash and fines desulfurization waste gases by the lime method - lime-ash ash. The ratio of components is selected in such a proportion that in the finished product the content of CaO is increased to 45-50%, and the content of F3 is up to 8-12%. The mixture is fired in kilns at a temperature of 1150-1250 ° C and finely ground after firing.
Подобное же в жущее может быть получено и следующим видоизменённым СПОСОбоМ.A similar pending can be obtained and the following modified way.
Смесь тонко изм-ельчённых: 1) известн ка и глины (или мергел ) или 2) известн ка и золы в такой пропорции , чтобы в готовом продуктеA mixture of finely ground: 1) limestone and clay (or marl) or 2) limestone and ash in such a proportion that in the final product
содержание СаО было доведено до 40-45%, обжигаетс в печах при температуре 1150-1250 и после обжига тонко измельчаетс с добавкой 15-20% гипса, предварительно обожжённого при температуре 1200-1250°.the CaO content was increased to 40–45%, burned in kilns at a temperature of 1150–1250, and, after calcination, finely ground with the addition of 15–20% gypsum previously calcined at a temperature of 1200–1250 °.
