摘要
选择地理位置相同的两个2000t立式油罐,在罐体表面分别涂乳白色防晒涂料和银灰色普通涂料,注满同批次国标四级菜籽油后储存一年,在此期间每隔7天扦样检测1次,分析环境温度与油温,及油脂酸值、过氧化值等关系,掌握存油品质变化规律。结果表明,无论是否使用防晒涂料,油脂的劣变速度都比较缓慢,但涂防晒涂料油罐的存油品质优于涂普通涂料油罐的存油,有利于从科学储油管理和企业经济效益方面指导实际工作。
Two vertical oil tanks with the capacity of 2000 tons of rape oil were sealed in the same geological position, one was painted with ivory--white sunproof dope and the other with silver gray ordinary dope. Both of them were filled with rape oil of fourth degree in one batch and were stored for one year. In the storage period samples were taken every seven days. The enviromental temperature and the temperature of the oil were analyzed as well as the relationship among lipidic acid, the value of peroxide etc.. The result showed that whether the anti--sun paint was used or not, the deterioration speed of the oil was always relatively slow, but the quality of the oil stored in tank with sunproof dope is better than the oil stored in the tank with ordinary dope.
