掺于建筑砂浆中的KF微孔塑化剂(简称KF剂)是一种引气型的化学外加剂;它是以松香酸钠与烷基苯磺酸钠为主要成分,加入适量无机化合物复合而成的砂浆外加剂。生产工艺简便,性能可靠。通过微观、亚微观测试,对KF剂的作用机理进行了较深入的研究。试验室的工作及工程应用证明,KF剂掺于砂浆中,使砂浆具有良好的塑化效应,显著改善它的流动性与保水性。在砌筑和抹灰砂浆中掺入微量KF剂,可取代全部或部分白灰膏,节约了能源及原材料,改善施工环境,减轻劳动强度,降低了成本,经济效益显著。
The KF microporous plasticizer (abbreviated as KF agent) incorporated into the building mortar is an air-entraining chemical admixture; it is composed mainly of sodium rosinate and sodium alkylbenzene sulfonate, and is compounded with an appropriate amount of inorganic compounds. Mortar additives. The production process is simple and reliable. Through microscopic and submicroscopic tests, the mechanism of action of KF agents was studied in depth. The laboratory work and engineering application prove that KF agent is mixed in the mortar to make the mortar have a good plasticizing effect and significantly improve its fluidity and water retention. The incorporation of trace KF in masonry and render mortar can replace all or part of the white plaster, save energy and raw materials, improve the construction environment, reduce labor intensity, reduce costs, and have significant economic benefits.
