Abstract
The invention discloses a degradable non-pollution environment-friendly flying dust inhibitor and the production method thereof. The material components are carboxyl cellulose sodium 0.3-2, modified starch 0.5-3, water 95-99.2. The invention includes the following steps: two third of the water volume and the carboxyl cellulose sodium are added into a reaction kettle; the carboxyl cellulose sodium is selected from methyl cellulose sodium and ethyl cellulose sodium, and is heated to 80-100 DEG C by steaming; after the carboxyl cellulose sodium is completely dissolved, the modified starch is added into slowly, and is stirred so as to be completely dissolved. The invention is a physical novel efficient flying dust preventing technology, the coverage principle is to use active adhesive to excite the activity of the bug dust on the surface of the flying dust, and to react with the active constituent of the flying dust to produce a sticking layer. The invention firms the bug dust on the surface of the flying dust by the enhancing function of a little of additive, has certain strength, and then can achieve the purpose of preventing flying dust. The invention is a degradable non-pollution environment-friendly covering agent.
Description
Technical field
The present invention relates to a kind of chemicals and production method, suppress the preparation and the production method thereof of airborne dust specifically.
Background technology
At present, the main atmospheric polluting material in the most of northern city of China is a pellet.Although it is a lot of to influence in the atmosphere factor of particulate matter, the airborne dust influence that coal yard and other diffusing stacking yard material stock ground (as the stacking field of tailings area, working-yard, material of construction and various place where the garage is piled ups etc.) produce particular locality can not be ignored.The main source of dust pollution is an airborne dust, battle field, Tu Chang in the construction site, and all there are serious airborne dust and starting material oneself consumption problem in the coal yard of enterprise, ash field and raw material, breeze, cindery accumulation place.These materials mostly are air storage greatly or spread at the stand.The surface, stock ground that spread at these air storages or stand, disturbance as air-flow (wind-force) will produce airborne dust, certainly will produce surrounding environment and pollute, as the high wind effect, can form local dust pollution band, this also is to cause one of higher major reason of pellet index in the northern city atmospheric environment, has caused serious harm to environment and HUMAN HEALTH.In the prior art, general employing regularly water spray is handled, because moisture evaporation is fast, and sprinkling frequency height, labour intensity is big, a large amount of waste water resources, and airborne dust DeGrain.
Summary of the invention
The object of the invention provides a kind of degradable free of contamination environment-friendly type Fugitive dust inhibiting agent.
Another object of the present invention provides a kind of production method of Fugitive dust inhibiting agent.
The present invention makes raw materials of effective components consisting of of percentage composition meter by weight:
Carboxy cellulose sodium 0.3～2, modified starch 0.5～3, water 95～99.2; Carboxy cellulose sodium is selected from sodium carboxymethylcellulose pyce and ethyl cellulose sodium, and modified starch is selected from esterification modified starch and α-change modified starch.
The production method of Fugitive dust inhibiting agent of the present invention comprises the following steps:
(1), in reactor, put into 2/3 of the water yield, add carboxy cellulose sodium, carboxy cellulose sodium is selected from sodium carboxymethylcellulose pyce and ethyl cellulose sodium, feed steam-heated cal(l)andria to 80 ℃～100 ℃, after carboxy cellulose sodium is all dissolved, add modified starch slowly, be stirred to whole dissolvings;
(2), add the water yield of residue 1/3, stir, be finished product.
The present invention is a kind of new and effective anti-airborne dust technology of physics method, and efficient insulating covering agent is made up of reactive adhesive and a small amount of auxiliary.Formation has the cured layer of certain intensity, covering airborne dust surface, it covers principle is to utilize reactive adhesive to excite airborne dust surface dust activity, react with the dust active ingredient, generate adhesive layer, and the enhancement by a small amount of admixture, make the dust curing of airborne dust top layer, and have certain intensity, thereby reach the purpose of anti-airborne dust.And be a kind of degradable free of contamination environment-friendly type insulating covering agent.
Insulating covering agent of the present invention is a kind of binding agent, during use it evenly is sprayed on particle surface, forms cured layer.This cured layer not only can bond together the pulverized coal particle of various particle diameters, and certain toughness is arranged, and can prevent airborne dust effectively.Simultaneously, according to environment protection requirement, this binding agent in process of production with use after, all can not produce new pollution to environment.Selecting with the synthetic high polymer in the organic and inorganic and natural adhesive of existing report is emulsion-type (water-based) insulating covering agent that base-material is re-dubbed, and has excellent practicality, and the semi-permeable membranes of formation has very strong cementing properties, toughness and tensile strength; According to practical situation, repetition test is determined the proportioning of each base-material, filler.Insulating covering agent is nontoxic, have no side effect, and cheap, excellent performance is free from environmental pollution, and raw material easily purchases, easy to use.
Environmental monitoring junction centre in Gansu Province's is left loading station (being adhesive for spraying) to train and is carried out the monitoring of Train Dynamic test airborne dust, and monitoring result sees Table 1, table 2.
