Dry-mixed mortar production process
The invention discloses a dry-mixed mortar production process, relates to the field of building materials, and aims to solve the problem of how to prepare mortar by utilizing industrial wastewater andwaste residues. According to the technical scheme, the dry-mixed mortar production process is characterized by comprising the following steps: 1) pretreatment: taking wastewater discharged from a papermaking machine, and adding clear water for mixing; 2) flocculation: adding a flocculating agent into the pretreated liquid, and carrying out a stirring reaction to obtain flocculated fibers; (3) cleaning: discharging redundant water in the flocculated fibers, and then cleaning the flocculated fibers with clean water; 4) proportioning mixture: adding the clear water and the flocculation fibers into a barrel to be mixed; and 5) pulping: adding the steel slag powder, the coal ash, the cement ash, the gypsum and the quartz sand to be mixed and stirred to be uniform, According to the dry-mixed mortar production process, the wastewater generated by papermaking is combined with the industrial waste residues, and thus the mortar high in ageing resistance is prepared.
本发明公开了一种干粉砂浆生产工艺，涉及建筑材料领域，旨在解决如何利用工业废水废渣配置砂浆的问题，其技术方案要点是：一种干粉砂浆生产工艺，其特征在于：包括以下步骤：1）预处理：取从抄纸机排出的废水，加入清水进行混合；2）絮凝：将预处理后的液体加入絮凝剂进行搅拌反应获得絮凝纤维；3）清洗：将絮凝纤维中多余的水排出后再用清水清洗；4）配比混合液：将清水与絮凝纤维加入桶中进行混合；5）制浆：加入钢渣粉、粉煤灰、水泥灰、石膏、石英砂进行混合搅拌均匀。本发明的一种干粉砂浆生产工艺将造纸产生的废水和工业废渣进行结合，从而配置抗老化能力强的砂浆。
