Embodiment 1

[0015] Example 1: Take any acrylic superabsorbent resin on the market (the amount is sufficient to absorb water in the oil-water mixture as a reference), put it in the oil-water mixture, and stir it fully to increase the amount of acrylic superabsorbent resin and the oil-water mixture Contact opportunity, after the acrylic super absorbent resin is fully absorbed until it is saturated, wrap it with gauze or metal mesh with a pore diameter of less than 50μm, and squeeze it so that the oil adsorbed on the acrylic super absorbent resin will be removed from the acrylic Shedding on super absorbent resin. The pressure of the squeezing is capable of making the oil adsorbed on the acrylic super absorbent resin completely fall off from the acrylic super absorbent resin.

[0016] The following is a reference experimental study:

[0017] 1) Study on the specificity of water absorption

[0018] Put 0.5g of acrylic super absorbent resin into a 100ml beaker filled with water, take it out after th...

Abstract

The invention relates to the field of an energy-saving and environment-friendly application material and particularly relates to application of acrylic acid series high-water-absorption resin. The acrylic acid series high-water-absorption resin is used for oil-water separation, and the application comprises the specific steps: putting the acrylic acid series high-water-absorption resin into an oil-water mixture and sufficiently stirring; after the acrylic acid series high-water-absorption resin sufficiently adsorbs the oil-water mixture to be saturated, covering the acrylic acid series high-water-absorption resin with a gauze or metal mesh with the pore diameter less than 50mum; and extruding the resin. By utilizing different adsorption specificities on oil and water of the acrylic acid series high-water-absorption resin, oil-water separation is realized, and particularly the separation between thick oil and water is realized.

Description

Technical field [0001] The invention relates to the field of energy-saving and environmentally-friendly applied materials, in particular to the application of an acrylic super absorbent resin. Background technique [0002] A large amount of oily wastewater has caused serious pollution to the environment. In order to achieve oil-water separation, the material is required to have hydrophobic and lipophilic properties or hydrophilic and oleophobic properties. So far, these two materials have been greatly developed and achieved certain results, but the separation of heavy oil and water is still pale. In addition, the waste oil produced by automobiles, ships, airplanes and other machinery and equipment will contain a small amount of water. How to remove the water in the viscous waste oil is related to the recycling of waste oil and the protection of environmental pollution. Because these oils have a relatively high viscosity, it is difficult to separate them with traditional hydroph...
