摘要:
在石蜡中加入十二烷基苯磺酸钠、吐温80等表面活性剂制备出新型石蜡防水剂,掺入到磷建筑石膏中制备试块,再分别与掺入石蜡和空白组进行对比,分析了其防水机理和对磷建筑石膏性能的影响,以及不同类型、掺量表面活性剂对新型石蜡乳液的作用机理.分析可得,掺入的新型石蜡防水剂所制备的磷建筑石膏试块具有较好的防水性能,且当新型石蜡防水剂掺入量为06%的时,软化系数达到0.78,与空白组相比提高了90%.当掺入量为1%时,磷建筑石膏吸水率与掺入量为0.2%相比降低了41.9%,比空白组降低了60.4%.
Abstract:
A new paraffin waterproofing agent was prepared by adding Sodium dodecylbenzene sulfonate and Twain 0 .80 surfactants into the paraffin wax, and the test blocks were added to phosphorus building gypsum. The waterproofing mechanism and the influence on the energy properties of phosphogypsum gypsum were analyzed respectively, and the mechanism of different types and dosage of surfactants on the new paraffin emulsion was compared. The results show that the phosphorus building gypsum sample prepared by adding new paraffin waterproofing agent has better waterproofing performance, and when the new paraffin waterproofing agent is 0.6%, the softening coefficient reaches 0.78, which is 90% higher than that of the blank group. When the content of phosphorus building gypsum is 1%, the water absorption of phosphorus building gypsum is 41.9% lower than that of 0.2% and 60.4% lower than that of blank group.
