利用天然混合羧酸与聚氧丙烯醚以适当比例混合 ,以乙醇为溶剂制得新型集油剂 ,燃点 88.7℃ ,对于水面柴油、原油膜有优良的集油性能。QS - 1集油剂在 5 5cm长的水槽中 ,使水面柴油膜收缩距离达 44 .0～5 0 .8cm ,维持时间大于 6h ;QS - 2集油剂使原油膜面积收缩率 74.3%～ 76 .5 % ,维持时间大于 16h。该集油剂在 0～ 40 0 0mg/dm3 浓度下 ,不影响小球藻和小新月菱形藻生长。该集油剂在 4级海况条件下仍具有集油能力。 Using natural mixed carboxylic acid and polyoxypropylene ether in proper proportions to mix, ethanol is used as solvent to make a new oil collecting agent with a flash point of 88.7 DEG C, which has excellent oil collecting performance for surface diesel oil and crude oil film. QS - 1 oil collection agent in a 5 5cm long tank, so that the surface water film shrinkage distance of 44.0 ~ 5.08cm, the maintenance time is greater than 6h; QS - 2 oil collector oil film area shrinkage of 74.3% 76.5%, maintaining more than 16h. The concentration of 0 ~ 40 0 ​​0 mg / dm3 did not affect the growth of Chlorella sp. The oil-setting agent still has oil-gathering ability under the condition of 4-level sea state.
