1原材料质量优化技术1.1原材料处理多孔砖的成型阻力比实心砖大,从内燃料方面说,如果内燃料粒度粗掺量大,会增加泥缸的阻力,造成泥缸发热,泥条发酥而开裂,因此,内燃料必须经过细碎和筛分,其最大粒度不能超过2mm。如果是掺入低塑性原料中,粒度应控制在1.5mm以下,否则难以保证成型质量。为了提高混合料的成型性能,可采取以下措施:其一控制原料粒度,原料内不得含有碎石和草根,粒度在2mm以下。其二对原料进行充分的陈化处
1 Optimization of raw material quality 1.1 Raw material processing Porous brick forming resistance than solid brick, from the fuel side, if the coarse fuel content of the large amount of internal fuel will increase the mud tank resistance, resulting in mud tank fever, mud crisp and hair Cracking, therefore, the internal fuel must be crushed and sieved, the maximum particle size can not exceed 2mm. If it is mixed with low plasticity raw materials, the particle size should be controlled below 1.5mm, otherwise it is difficult to guarantee the forming quality. In order to improve the formability of the mixture, the following measures can be taken: The first control of raw material size, raw materials shall not contain gravel and grass roots, particle size below 2mm. The second of the full aging of raw materials
