文章通过正交试验,研究了木质素磺酸钠、十二烷基苯磺酸钠、增强剂JF1、稳定剂HM2对预拌抹灰砂浆性能的影响,使用JMP软件预测,得到了一种砂浆增塑剂的最优配比,并进行了试验验证;对比研究了掺与不掺增塑剂砂浆的性能。结果表明,研制出的增塑剂不仅能够明显改善新拌砂浆的和易性,而且能够提高硬化砂浆的强度性能,各项技术指标满足相关规范的要求。
The effects of sodium lignosulphonate, sodium dodecylbenzenesulfonate, enhancer JF1 and stabilizer HM2 on the performance of ready-mixed plaster mortar were studied by orthogonal test. Using JMP software, a mortar Plasticizer optimal ratio, and the experimental verification; Comparative study with and without plasticizer mortar performance. The results show that the developed plasticizer not only can significantly improve the workability of the fresh mortar, but also can improve the strength properties of the hardened mortar. The technical indicators meet the requirements of relevant specifications.
