Abstract
The invention discloses a kind of dust fixing agent.It contains the component of following weight part: Calcium Chloride Powder Anhydrous, polyacrylamide, carboxymethyl cellulose, inhibiter.This product is a kind of nontoxic, harmless, odorlessness, to a kind of powdery product that human body and skin have no adverse reaction, composition is simple, and each composition all can use in food grade products, and human body is not all had any infringement to plant.
Description
Technical field:
The present invention relates to a kind of dust fixing agent.
Background technology:
Material because of producing relative movement with air, causes fine particle to fly upward in the air in conveying, loading and unloading, stacking process, forms dust.In coal-fired power plant, coal handling system is main dust source of generation, and the dirt source mainly goes out at coal yard, run coal bin top, coal pulverizer/and inlet and coal crusher house, vibration feeder, coal conveyer belt transfer point and Belt Passage ground etc. are located.In the time of can being used for train transportation coal, prevent that coal from flying upward loss and polluting environment on the way, flying upward of coal caused great pollution for year in year out the railway surrounding enviroment, and be that the flowers, plants and trees of periphery has so and withered.
From point of view of environment protection, dust is the formidable enemy of HUMAN HEALTH.Especially particle diameter floats dirt between 5～0.5 μ m, can be long-term in addition several years buoyant atmosphere in, to the harm maximum of human body.Grit greater than 5 μ m is held back by vibrissa, respiratory tract mucus because of being subjected to inertia effect, also be attached on upper respiratory tract surface and excrete less than the grit of 0.5 μ m with phlegm, sneeze etc., only 0.5～5 μ m's floats dirt and then can directly arrive lung by respiratory tract, the overwhelming majority is trapped in and forms fibrous tissue in the alveolar, produce various diseases such as breathing function obstacle, silicosis is exactly wherein a kind of.According to one's analysis, some to float the dirt microparticle surfaces be the arch-criminal of various poisonous substances in the atmosphere with the dust of carinogenicity very strong aromatic hydrocarbons, especially coal also.Dust thin more in air the residence time long more, the chance that is sucked by people is just many more. so just be " imbedibility dust " less than the dust of 5 μ m, because of its specific surface area big, surfactivity is strong, energy adsorbed gas and metal ion, in the nineteen fifty-two London smog episode, sulfurous gas is exactly to be carrier with the following dust of 5 μ m, sucks alveolar and causes disaster.
Along with the development of modern society's civilization, also more and more higher to environmental protection requirement, therefore, treating flour dust is the Important Project that is related to environment protection, health of human body, is long-term, a difficult task, is subjected to the generally attention of countries in the world.
Summary of the invention:
The dust fixing agent that the object of the present invention is to provide a kind of nontoxic, harmless, odorlessness, human body and skin are had no adverse reaction.
Another object of the present invention is to provide the preparation method of dust fixing agent.
First purpose of the present invention is implemented by following technical scheme: dust fixing agent, it contains the component of following weight part: Calcium Chloride Powder Anhydrous 750-850 part, polyacrylamide 5-25 part, carboxymethyl cellulose 15-50 part, inhibiter 5-20 part.
Dust fixing agent, it contains the component of following weight part, and its most preferred range is: Calcium Chloride Powder Anhydrous 750-850 part, polyacrylamide 5-25 part, carboxymethyl cellulose 15-25 part, inhibiter 5-10 part.
Described inhibiter is made up of the component of following weight part: hydrazine hydrate 15-35 part, benzotriazole 2-10 part, potassium hydroxide 10-15 part, glucose 15-20 part.This inhibiter is the high-efficient corrosion inhibitor at the chlorion medium in the calcium chloride water; can effectively suppress the corrosion of metal damage of chlorion to contacting; slow down the destruction of chlorion to metal surface protection film and intergranular structure; the work-ing life of significant prolongation hardware; add inhibiter, can prevent the damage that dust fixing agent causes the metallic facility that contacts.Nontoxic non-corrosiveness, safe and harmless, pollution-free to environment for use.
Another object of the present invention is to provide a kind of preparation method of dust fixing agent: above-mentioned component 80 ℃～150 ℃ meltings, is fully stirred, is cooled to below 80 ℃, pulverize, after sieving now in 60 orders～150, promptly make dust fixing agent.
Advantage of the present invention: this product is a kind of nontoxic, harmless, odorlessness, to a kind of powdery product that human body and skin have no adverse reaction, and composition is simple, and each composition all can use in food grade products, and human body is not all had any infringement to plant.Dust fixing agent has used calcium chloride very easily to absorb the characteristic of airborne moisture content; thereby make product have fabulous moisture-keeping functions; can form deadlock; and be not easy to carry out percdation; as on the powdery stores, using; can on the powdery stores, form the viscosity hardening layer of about 5-8cm, need set thing is played a very good protection, can effectively prevent dust from flying.In the working space that dust from flying is arranged, the solution with this product changes into carries out vaporific sprinkling, and the dust in the absorbed air and fly upward thing will airbornely fly upward thing absorption sedimentation afterwards effectively, play the effect that purifies air.The user can apply in a flexible way according to practical situation when using this product.This product has high deliquescence, the dust particle in the absorbed air very easily, and easily form and harden, and the deep layer that is difficult for infiltrating stores causes waste, is a kind of economical and practical dust fixing agent efficiently.This product has nontoxic to the harmless characteristics of environment, and setting time is short, and the characteristics of longer duration do not have special influence to set thing especially coal, and are safe and convenient to use, advantage of wide range of application.
