Embodiment 1

[0008] Embodiment 1 adopts n-hexanoic acid solution containing 20% ​​(by weight) stearyl alcohol as the oil collector of the present invention. In order to test the effect of the oil collecting agent of the present invention, inject tap water or sea water in the water tank of 55 * 5 * 5cm, the thickness of water layer is about 3cm, inject 10ml diesel oil (or other oils) on one side of the water tank, and wait for the oil film to spread to the other side. Use a graduated dropper to drop 1 drop of this oil collector, and you can see that the oil film shrinks back immediately. When the shrinkage stops, add another drop of oil collector until the oil film no longer shrinks. Record the oil film The position in the tank (marked with centimeter paper) changes with time, and the oil-collecting effect of the oil-collecting agent is characterized by the shrinkage percentage of the oil film at different times. The maximum oil-collecting effect of this oil-collecting agent on diesel oil i...

Embodiment 2

[0010] Embodiment 2 adopts the isoamyl acetate solution containing 15% stearyl alcohol. The oil-collecting agent can make the maximum shrinkage rate of diesel oil on the water surface reach 89%, and the 24-hour oil film shrinkage rate still remains at 62%.

Embodiment 3

[0011] Embodiment 3 adopts the heptanoic acid solution that contains 10% octadecanoic acid. The oil-collecting agent can make the maximum shrinkage rate of the oil film on the water surface reach 80%, and the shrinkage rate of the oil film remains at 70% within 72 hours.

Abstract

The oil film collecting agent on water includes active components and carrier, and features the active components includes solid fatty alcohol, solid fatty carboxylic acid, anhydrosorbic fatty acid ester or their mixture and accounts for 1-25 wt%. The present invention is simple in composition, low in toxicity, biodegradable, and has high oil collecting efficiency on oil film on water of raw oil, diesel oil, kerosene, gasoline, machine oil, vegetable oil, etc.

Description

technical field [0001] The invention relates to a water treatment agent, in particular to a water surface oil film oil collecting agent which controls the diffusion of the oil film on the water surface, makes the oil film gather and thicken, and is easy to recover and treat by mechanical or physical and chemical methods. Background technique [0002] In the operation of removing oil film on the water surface to prevent oil film pollution, some people use oil collecting agent; also known as oil gathering agent, oil compressing agent, piston film, chemical oil containment boom, and monomolecular film. It can thicken the diffused oil film on the water surface, change and control the diffusion direction of the oil film on the water surface, and achieve the purpose of reducing or controlling the pollution damage of the oil film on the water surface. The thickness of the oil-collecting agent is related to the properties of the oil-collecting agent (film pressure, density), the pro...
