Abstract

The invention discloses a whitening agent prepared from lime sulfur residues. The whitening agent comprises lime sulfur residue powder, calcium powder and rubber powder, wherein the adding ratio of the lime sulfur residues to the calcium powder is 1: 1, the lime sulfur residue powder is 400-600 meshes, and the weight of the rubber powder accounts for 3-8% of the total weight of the lime sulfur residue powder and the calcium powder. The whitening agent has the beneficial effects that the spraying efficiency is high, waste is avoided, and lime sulfur has the sterilization and egg killing effects; after being sprayed, the whitening agent is slowly oxidized into calcium carbonate in air and is neutral, and soil under trees cannot be damaged by alkalinity after rain wash; and air holes are formed in the oxidation process to keep the air permeability of the tree.

Description

technical field [0001] The invention relates to the field of tree trunk protective paints, in particular to a whitening agent prepared by utilizing the residue of a lime sulfur mixture and a method for using the same. Background technique [0002] Lime-sulfur mixture is a kind of fungicide used in agriculture, which is made from quicklime, sulfur and water. Cooking lime sulfur mixture liquid produces a large amount of lime sulfur mixture residue. For lime-sulfur mixture manufacturers, lime-sulfur mixture residues are solid wastes, which are generally sold at low prices or even lose money to use nearby farmland as a whitening agent. The status quo is that the residue after the production of lime-sulfur mixture becomes a kind of solid waste that cannot be dealt with. The solid after passing through the filter press contains 15% of sulfur, 70% of calcium hydroxide, 70% of calcium polysulfide and 5% of calcium polysulfide. Now most factories use landfill, so that many useful c...
