目前,国内各混凝土预制工厂采用的隔离剂大体有肥皂、废机油、柴油、松香汽油溶液和石蜡等,惟其不是在效果上就是在使用上存在这样或那样的问题.我厂在生产预应力钢筋混凝土轨枕时,尝试使用了盘锦炼油厂在石油加工中产生的常压三线、减压一线油(俗称蜡油,裂化油)做隔离剂,收到了较好的效果.主要表现在:脱模顺利,模型内残留 At present, the isolation agents used in domestic concrete prefabricated factories generally include soap, waste engine oil, diesel oil, rosin gasoline solution, and paraffin wax. However, they are not in effect in use or have such problems. Our factory is producing prestressed steel bars. When concrete sleepers were used, Panjin Refinery tried to use the normal pressure three-line and decompression first-line oils (commonly known as wax oil, cracked oil) produced in petroleum processing as the release agent, and received good results. The main performance is: smooth demoulding. , residual in the model
