同实心砖比较,空心砖的生产难度大,工艺要求高,操作技术严。要想生产出合格的空心砖,必须掌握关键技术。根据我在空心砖新产品试制工作中的体会,生产空心砖需要注意以下几点: 一、原料的加工处理原料最好是中等塑性以上的粘土。对原料的加工处理应比实心砖好一些;非承重空心砖的要求又比承重空心砖高一些;特别重要的是原料中最好不含杂质,有杂质一定要剔除。原料含礓石是空心砖生产的大忌。因为料礓石在成型过程中易堵塞在芯架之间和芯头之间,且
Compared with solid bricks, the production of hollow bricks is difficult, the process requirements are high, and the operation technology is strict. To produce qualified hollow bricks, you must master key technologies. According to my experience in the trial production of new products for hollow bricks, the following points should be noted in the production of hollow bricks: 1. Raw materials must be processed and treated with clays of medium or higher plasticity. The processing of raw materials should be better than that of solid bricks; the requirements of non-load-bearing hollow bricks are higher than those of load-bearing hollow bricks; it is especially important that the raw materials contain no impurities, and impurities must be removed. The raw material containing vermiculite is a taboo for the production of hollow bricks. Because the material stone is easy to clog between the core frame and the core head during the molding process, and
