Embodiment 1

[0092] Example 1 : phosphate rock dust suppressant of the present invention

[0093] The preparation method is as follows:

[0094] A, 0.5 parts by weight of water-soluble polyvinyl alcohol (degree of polymerization 1700, degree of alcoholysis 88) are dissolved in 100 parts by weight of water to obtain a kind of said polyvinyl alcohol solution;

[0095] B, slowly add 1.0 parts by weight of guar gum to the polyvinyl alcohol solution obtained in step A) under stirring, and continue stirring until the guar gum is completely dissolved;

[0096] C, in the solution that step B) obtains, add 0.001 weight part D-581 sterilizer, 1.0 weight part coconut oil fatty acid diethanolamide surfactant again, then stir to obtain uniform solution again;

[0097] D. Allow the solution obtained in step C) to stand for 6 hours, and filter to obtain the phosphate rock dust suppressant.

[0098] The viscosity of the phosphate rock dust suppressant is 263 mPa·S, the thickness of the solidified layer...

Abstract

The invention relates to a phosphorus ore dust suppressant composition and a preparation method thereof. The phosphorus ore dust suppressant composition comprises water-soluble polyvinyl alcohol, guar gum, microbicide, and water. The phosphorus ore dust suppressant provided by the invention can form a solidifying layer with certain strength and tenacity on the surface of phosphorus ore or powdered ore, which allows granular or powdered phosphorus ores to bond together, so as to effectively suppress dust emission of powder phosphate ores. The phosphorus ore dust can also be used for treatment of soil desertification and dust suppression at construction sites or dust suppression of other ores and can not pollute environment.

Description

【Technical field】 [0001] The invention belongs to the technical field of environmental protection. More specifically, the present invention relates to a phosphate rock dust suppressant composition, and also relates to a preparation method of the composition. 【Background technique】 [0002] Phosphorus is an important component of biological cytoplasm and an essential element for plant growth. 84% to 90% of the world's phosphate rock is used to produce various phosphate fertilizers, 3.3% to produce feed additives, 4% to produce detergents, and the rest are used in chemical industry, light industry, national defense and other industries. In China's phosphate rock consumption structure, phosphate fertilizer accounts for 71%, yellow phosphorus accounts for 7%, phosphate accounts for 6%, and phosphide accounts for 16%. Phosphorus fertilizer plays an important role in increasing the yield of crops. [0003] The distribution of phosphate rock in my country is extremely uneven, an...
