Method for preparing deformation-free wallboard from engineering residue soil
The invention discloses a method for preparing a deformation-free wallboard from engineering residue soil, which comprises the following steps: 1, carrying out experimental analysis on the engineering residue soil to obtain a plasticity index; 2, carrying out plasticity adjustment on the engineering residue soil according to the plasticity index to obtain a mixture; and 3, sequentially carrying out extrusion molding, drying and sintering on the mixture to obtain the wallboard without buckling deformation. The scheme that plasticity adjustment is determined according to the plasticity index is adopted, the plasticity index is adjusted to be 15-17, the charge number, the specific surface area, the inter-particle capillary force and the water film thickness of the surfaces of raw material particles are adjusted from the microscopic angle, the special requirements of a sintered plate for forming, drying and roasting are met, and then extrusion forming, drying and sintering are carried out to obtain the high-strength and high-toughness sintered plate. The indexes such as total shrinkage, buckling deformation and product strength are controlled, so that the buckling deformation problem of the wallboard is greatly improved, the wallboard without buckling deformation is obtained, a large amount of industrial solid waste is turned into wealth in the green and low-carbon process, and the development of prefabricated buildings is assisted.
本发明公开了一种工程渣土制备无变形墙板的方法，包括以下步骤：一、将工程渣土进行试验分析，得到塑性指数；二、根据塑性指数对工程渣土进行塑性调整，得到拌合料；三、将拌合料依次进行挤出成型、干燥和烧结，得到无翘曲变形的墙板。本发明根据塑性指数决定塑性调整的方案，使塑性指数调整为15～17，从微观角度上调整原料颗粒表面的电荷数、比表面积、颗粒间毛细管力以及水膜厚度，满足烧结板材对成型、干燥和焙烧的特殊需要，再通过挤出成型、干燥和烧结，控制总收缩、翘曲变形和制品强度等指标，使墙板翘曲变形问题极大改善，得到无翘曲变形的墙板，使大宗工业固废在绿色、低碳的过程中变废为宝，助力装配式建筑发展。
