摘 要:砂基透水砖是以细砂为面层骨料,以有机胶结剂为主要黏结材料,经免烧结成型工艺制备而成,具有透水功能的透水砖。但是由于其面层细砂尺寸较小,砂基透水砖在压制过程中通常会导致黏模问题,严重影响生产效率。本文以耐磨性为路用指标,采用压头残余黏结细砂法对砂基透水砖的黏模特性展开试验研究。通过分析制砖机压头残余黏结细砂量与胶结剂用量、细砂形状、细砂粒径、颜料添加量及成型压力的变化规律对砂基透水砖的性能进行研究。试验结果表明,当采用圆粒硅砂,胶水用量在4.0%~4.5%、细砂粒径为40~80目、颜料添加量为1.5%~2.5%,成型压力为21MPa时制备的砂基透水砖表面比较平整且具有较好的路用性能。
Abstract: Sand-based water permeable brick (SPB) is a kind of permeable brick which is made by sintering molding process with fine sand as the surface layer and organic adhesive as the main bonding material. However, due to its small fine sand size of surface layer, there is a sticking problem in the pressing process, which will seriously affect the production efficiency. The viscosity model experimental of SPB was studied by the method of residual cohesive fine sand on the head, while the wear resistance was as the indicator for the road. The properties of SPB were studied by analyzing the relationship of esidual cohesive fine sand on the head with dosage of the glue, sand shape, particle size, the content of toner, forming pressure. The results show that the SPB is smooth and has a good performance when the round grain of silica sand is used, the amount of resin sand ratio ranges from 4.0% to 4.5%, the fine sand grain size ranges from 40 mesh to 80 mesh, the toner content ranges from 1.5% to 2.5%, and the molding pressure ranges from 17MPa to 21MPa.
