hardened oil
    Some admixtures which may affect the compressive strength of hardened oil based slurry were studied to improve the mechanical properties and the specimen with 1%FeCl3 +5%silica fume + 3%F17A added showed the best results.
    试验研究了不同种类的化学外加剂和外掺料对硬化油基水泥石抗压强度的影响,结果表明:掺加FeCl3、硅灰和F17A的油基水泥石,其抗压强度提高程度最为显著,三者复合(1%FeCl3+5%硅灰+3%F17A)效果最佳。
    Process conditions of catalytic hydrogenation of lard at atmospherical pressure, of hydrolysis of hardened oil for producing stearic acid and glycerol, and of the exchange esterification for the preparing glyceryl monostearate are described.
    叙述了猪油常压催化氢化、硬化油水解制硬脂酸和甘油、甘油与硬化油发生交酯反应制备单硬脂酸甘油酯的工艺条件。
    This paper reports the results of industrial applications of the CIM catalyst for oil hydrogenation. It was shown that for the production of industrial hardened oil,the activity(space productivity per hour) of CIM-1 catalyst was five times as high as that of the traditional one,and the temperature of activation/reduction of CIM-1 catalyst was 150℃,30℃ lower than that of the traditional one,and the quality of the hydrogenated oil was raised for one grade.
    报道了CIMCu- Ni 油脂氢化催化剂的工业生产应用结果:1- 用于制工业硬化油,CIM-1催化剂的活性(时空产率) 是同类国产传统催化剂的5 倍,CIM- 1 催化剂的活化还原温度比同类传统催化剂低30 ℃。
    Therefore,the amount of CIM-1 catalyst used was only 1/4 of the traditional one,the output of hardened oil increased by 0.5%,the consumed energy was reduced,the life of the equipments was prolonged,the quantity of waste catalyst was reduced,and the labor productivity was raised.
    因而使催化剂用量降低到原来的14,硬化油产量提高0-5% ,质量提高一个档次;
    Mechanical measurements show that the compressional strength of hardened oil base cement varies significantly with changing the W/S ratio of OBCS and the highest strength is observed at intermediate W/S ratios of 0.2—0.3;
    力学性能测试表明,硬化油基水泥石的抗压强度随水浆比的变化而有很大的差别,水浆比适中时(0.20~0.30)抗压强度最高;
    The loss on ignition measurements show that the hydration degree of hardened oil base cement is affected mainly by the W/S ratio of OBCSs and in less extent by the curing temperature and the cement fineness and is low inough, accounting 33—64% in 7 days, for the hardened cement strength to develop further in some extent.
    烧失量法测定结果表明,硬化油基水泥石水化程度主要与水浆比有关,温度和水泥细度也有一定的影响; 7d龄期硬化油基水泥石水化程度较低(33%~64%),后期抗压强度仍有较大增长潜力。
