Abstract
The invention discloses a method for preparing hydrophobic sand from waste grease and fine sand. The main technical process comprises the following steps: heating waste grease, adding fine sand and stirring while keeping the temperature so that the waste grease is uniformly distributed on the surface of the sand, and cooling to obtain the hydrophobic sand. The hydrophobic sand prepared by the method has favorable properties. By using the waste grease and fine sand as raw materials, the method develops a new road for comprehensive utilization of the waste grease. The hydrophobic sand prepared by the method can be used in the aspects of water saving in urban landscaping as well as desert control, and is hopeful to have great actions in the fields of waste utilization, water saving, desert control and the like.
Description
Technical field
The preparation method who the present invention relates to can be used for city trees and shrubs, sand control and supply a kind of hydrophobic sand of other water saving fields application, referring in particular to waste grease and fine sand is the method that raw material prepares hydrophobic sand, hydrophobic sand refers to that the surface is covered by hydrophobic substance, and makes the not hydrophilic sand in surface.
Background technology
The present invention is primarily aimed at present shortage of water resources, irrigation water serious waste; Desertification is serious day by day, waste grease causes serious public hazards and not have the problem of aspects such as reasonable utilization.The fine sand that utilizes the very low fine sand of waste grease and cost to be covered by grease for a kind of surface of feedstock production because the surface of this sand is grease, therefore can not keep moisture, and not hydrophilic, and rainwater or irrigation water are permeated the ground smoothly; Because the fine sand surface is not hydrophilic, can effectively reduces moisture and absorb water with capillarity by soil simultaneously, and then evaporation causes the soil dehydration.
Because the present invention utilizes waste grease and sand to be raw material, the hydrophobic sand of preparation is with low cost, yet there are no the relevant report of this aspect, and its particular performances will have broad application prospects it aspect desertification control and urban afforestation and beautification of landscape (if during preparation at the surface attachment different colours of sand).
Summary of the invention
The technical problem to be solved in the present invention provides a kind of preparation method of hydrophobic sand, and this preparation method is main raw material with fine sand and waste grease, through reasonable proportioning, makes hydrophobic sand by certain technological process.
The technical problem to be solved in the present invention is solved by following scheme: a kind of is the method for feedstock production hydrophobic sand with the waste grease, it is characterized in that: waste grease is heated to 50 ℃-100 ℃, add fine sand down for 50 ℃-100 ℃ at heat tracing, under heating, stir, waste grease evenly is attached to the fine sand surface, namely get hydrophobic sand behind the naturally cooling, wherein the mass ratio of waste grease and fine sand is 1:12-17.
Above-mentioned a kind of be that waste grease in the method for feedstock production hydrophobic sand refers to: discarded animal grease, discarded plant grease, sewer oil and industrial waste oil product with the waste grease.
Above-mentioned a kind of be that fine sand in the method for feedstock production hydrophobic sand refers to: the sand in sea sand, river sand and other sources with the waste grease.
Advantage of the present invention is: 1, very low with the husky cost of the hydrophobic of present method preparation.2, the sand surface is covered by very thin waste grease, thereby not hydrophilic.3, being applied to urban afforestation or desertification control can save irrigation water, reduce evaporation to suppress the process of desertification, to reach the purpose of water saving and improvement desertification.4. a large amount of waste greases that can effectively utilize the city to produce are made rational use of resources and are alleviated the pollution that waste causes.
