Hydrophilic oleophobic adsorption particle for chemical industry

Abstract

The invention relates to a hydrophilic oleophobic adsorption particle for the chemical industry. The hydrophilic oleophobic adsorption particle comprises skin and at least one inner core wrapped by the skin, wherein the skin is a hydrophilic oleophobic layer which is synthesized through a bonding reaction of hydrophilic groups with a polar group contained in a fluorocarbon active agent; the skin is of a two-layer structure, an outer hydrophilic oleophobic layer is a of membrane structure, and an inner hydrophilic oleophobic layer is of a porous structure; and the inner core is made of a water-absorbing material. The adsorption particle is put into the lubricating oil, and the skin of the adsorption particle can isolate oil and permits permeation of water; and water that has entered the adsorption particle through the skin is adsorbed by the inner core.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a hydrophilic and oleophobic adsorption particle for chemical industry. Background technique [0002] In the field of chemical industry, water ingress in lubricating oil often occurs in chemical equipment. Once water ingress occurs in chemical equipment, it will cause abnormal noise or other problems in the operation of the equipment, and it will also cause poor lubrication effect of chemical equipment. Severe wear or high temperature between the mechanisms will cause damage to the equipment. [0003] The traditional method is dehydration by heating and cooking, but for oil products with low flash points such as gasoline, kerosene, diesel and other flammable chemicals, using heating and cooking is likely to cause fire or explosion, and the risk is high. The traditional oil-water separation adopts pro- The oil-hydrophobic material realizes water resistance and oil passage. Compar...

Severe wear between mechanisms or high temperature, resulting in equipment damage

[0003] The traditional method is dehydration by heating and cooking, but for oil products with low flash points such as gasoline, kerosene, diesel and other flammable chemicals, using heating and cooking is likely to cause fire or explosion, and the risk is high. The traditional oil-water separation adopts pro- The oil-hydrophobic material realizes water resistance and oil passage. Compared with water, oil has a higher viscosity, and it is easy to adhere to the filter mesh to block the mesh, which greatly reduces the filtration efficiency. Secondly, the density of water is relatively high, and the water contacts the filter first under the action of gravity. Omentum, it is easy to form a water film on the surface of the omentum, and oil with a lower density can only float on the water film, making the separation unsustainable
