Description

Изобретение относитс  к производству безобжиговых легковесных изделий и может быть использовано дл  футеровки тепловых агрегатов металлургической , нефтехимической, машиностроительной и других отраслей про- мьшшенности.The invention relates to the production of unburned lightweight products and can be used for lining thermal units of the metallurgical, petrochemical, engineering and other industries.

Цель изобретени  - снижение кажущейс  плотности и теплопроводности.The purpose of the invention is to reduce the apparent density and thermal conductivity.

Смесь готов т в зетообраэном смесителе из подготовленной сырьевой смеси влажностью 20-25% на гидравлическом прессе прессуют издели  в форме нормального кирпича. Отпрессованные издели  твердеют во влажных услови х в течение 3 сут.The mixture is prepared in a zebra pattern with a mixer from a prepared raw material mixture of 20–25% moisture in a hydraulic press that presses the articles in the form of a normal brick. Pressed products harden in wet conditions for 3 days.

Свойства изделий после твердени  и сушки при 110°С приведены в таблице .Properties of products after hardening and drying at 110 ° C are shown in the table.

Как видно из таблицы, издели  на основе предлагаемого состава по сравнению с прототипом имеют более низкие кажушуюс  плотность и теплопроводность .As can be seen from the table, products based on the proposed composition as compared with the prototype have lower apparent density and thermal conductivity.
