我厂原来是采用一般蒸汽养护的方法生产粉煤灰硅酸盐砌块的,自1963年10月采用无压純飽和蒸汽养护方法生产后,制品强度高,养护时間短,蒸汽耗用量低,效果良好。无压純蒸汽养护較之普通蒸汽养护設备,除了具有下排供气管外,还增設了上排供气管(見图1),另外还装置了带有直接作用調节器的冷凝設备及与大气相通的带有水封閥的φ108排气管。下部供气管专供养护池內升溫之用,当升温达90℃以上时,就关閉下排供气管,打开上排供气管。随养护池內供气量的逐漸增加,池內上部純蒸汽愈来愈多,使池內蒸汽与
Our factory originally used the method of general steam curing to produce fly ash silicate blocks. Since it was produced in October 1963 using the method of pressureless pure saturated steam curing, the product has high strength, short curing time, and steam consumption. Low, good results. Compared with ordinary steam curing equipment, the pressureless pure steam curing system also includes an upper air supply pipe (see FIG. 1) in addition to the lower air supply pipe, and a condensing device with a direct acting regulator. The φ108 exhaust pipe with water seal valve is open to the atmosphere. The lower air supply pipe is used exclusively for heating in the pool. When the temperature rises above 90°C, the lower air supply pipe is closed and the upper air supply pipe is opened. With the gradual increase in the amount of gas supply in the conservation pool, the upper part of the pool is getting more and more pure steam, so that the steam inside the pool
