Abstract
The invention provides a powdery material covering agent and a using method thereof, wherein the covering agent mother liquor comprises the following components: 30-40wt% of styrene acid, 40-50 wt% of sodium styrene carboxylate and 15-20 wt% of sodium benzoate. Mixing the mother liquid with water to obtain 9-11% aqueous solution, and spraying to obtain powderSpraying on the material pile, wherein the spraying amount is controlled to be 1-1.5kg/m2When spraying, the control spray gun outlet aqueous solution is the atomizing state, avoids aqueous solution to penetrate the powdery material heap surface directly to spray repair again to the place that does not spray, make it form one deck surface conjunctiva on the material heap surface, both can prevent powdery material's raise dust, avoid environmental pollution, can greatly reduce the wind damage and the rain loss of material again, avoid the corruption of material rotten, reduce material loss and material cost.
Description
Technical field
The invention belongs to raw materials for sintering storage technique field, particularly relating to a kind of for preventing insulating covering agent and the using method thereof of pulverulent material airborne dust and loss.
Background technology
Along with the optimization of SINTERING PRODUCTION technique, domestic sintering plant is provided with large-scale outdoor stock yard.Stock yard bears the storage of various material and the processing of sintering blending ore.Materials in stock yard kind is imported ore fines and coking coal mainly, mostly by sea transport to stock yard.Because most stock yard is located in coastal area, wind heavy rain is many, pulverulent material very easily airborne dust and being run off by rain drop erosion, not only causes scattering and disappearing and waste of raw material, and causes stock yard environmental pollution.
Under normal circumstances, the method that stock yard controls pulverulent material airborne dust covers stockpile, but due to pulverulent material storage capacity large, therefore need a large amount of to cover material, and consume a large amount of manpower.Moreover, and cover thing and with the passing of time very easily corrode, remain in material after breakage, both caused quality of material to decline, again certain impact is produced on production technique.
Summary of the invention
The present invention aims to provide one can prevent pulverulent material airborne dust and loss, improves stock ground environment, reduces pulverulent material insulating covering agent and the using method thereof of material windage loss and rain damage.
For this reason, the solution that the present invention takes is:
A kind of pulverulent material insulating covering agent, it is characterized in that, the one-tenth of described insulating covering agent mother liquor is grouped into and weight percent content is:
Vinylbenzene acid 30-40%, styrene carboxylic acid's sodium 40-50%, Sodium Benzoate 15-20%.
A using method for pulverulent material insulating covering agent as claimed in claim 1, is characterized in that:
Insulating covering agent mother liquor is watered the aqueous solution being mixed with 9-11%, after fully mixing in spraying vehicle, spray on powdery material stack with spray gun, fountain height controls at 1-1.5kg/m
2; Controlling the lance outlet aqueous solution during sprinkling is atomizing state, and spray gun is sprayed in the air above powdery material stack, avoids aqueous solution direct projection to powdery material stack surface; After big area is sprayed, carry out spray repair again to the place be not sprayed onto, the ensuring coverage agent aqueous solution all covers powdery material stack, makes insulating covering agent at powdery material stack surface conjunctiva.
Beneficial effect of the present invention is:
Owing to having sprayed the insulating covering agent aqueous solution on powdery material stack, layer of surface conjunctiva can be formed on stockpile surface after 24 hours, being covered by powdery material stack covers in conjunctiva, both the airborne dust of pulverulent material had been prevented, avoid environmental pollution, windage loss and the rain that greatly can reduce again material damage, and avoid the septic yeast of material, ensure materials quality, reduce loss of material and raw materials cost.For 50,000 tons of powdery material stacks, implement the present invention, the material more than 250 tons of windage loss and rain damage can be reduced every year.
