应用半干粘土压制砖坯,目前在我国的砖厂中还是一个新的成型方法.这种成型方法具有许多优点: (一)因成型水份低(约8-12%),干燥周期快,同时降低干燥损失,节约干燥用煤. (二)可以用来成型异型砖坯.如空心砖、五面砖及其他建筑材料. (三)可以完全避免塑性成型方法时产生的砖坯的螺旋纹结构.使砖坯六面规整、美观. (四)用此法成型的砖坯,湿度很小可完全不经干燥而直接焙烧,这样可以帮助季节性砖厂解决冬季生产问题.
The use of semi-dry clay to suppress bricks is currently a new method of molding in China’s brick factories. This method of molding has many advantages: (1) Because the molding water is low (about 8-12%), the drying cycle is fast and at the same time Reduce drying loss and save dry coal. (B) It can be used to shape shaped bricks, such as hollow bricks, five-brick tiles and other building materials. (C) The spiral structure of bricks can be completely avoided when the plastic forming method is used. The surface is regular and beautiful. (D) bricks formed by this method, the humidity is very small and can be directly baked without drying, this can help seasonal brick factory to solve the winter production problems.
