我厂过去生产预应力混凝土电杆使用的脱模剂是用40号机油、肥皂、滑石粉和水经混合加热溶解而制成的。虽然脱模效果较好,但材料用量大、价格贵、耗用蒸汽及污染电杆表面和操作现场。按平均月产各类电杆(12、10、9、8、6米)总和2300根计, The release agent used in the past to produce prestressed concrete poles in our factory is made by mixing and heating the 40# oil, soap, talcum powder and water. Although the demoulding effect is good, the amount of material is large, the price is expensive, steam is consumed, and the pole surface and operation site are polluted. According to the average monthly production of all kinds of poles (12,10,9,8,6 meters), the total number is 2,300.
