Description
Technical field
The invention belongs to ecological, environmental protective technical field, be specifically related to a kind of Coal Dust Restrainer and preparation method thereof.
Background technology
Coal, in the storage of harbour coaling wharf, power plant, coal yard etc. and the process of railway, highway and ship transportation, usually can produce a large amount of airborne dusts, not only directly threatens the safety of producing, and also can produce the environment of surrounding and pollute greatly.Therefore the research of coal dust suppression technology is the focus that people study always.What suppression coal airborne dust was the most frequently used is the method for sprinkling water.The Main Function of watering dust suppression is the dry coal dust that wet granulate is tiny, its relative density is increased, and is bonded to larger particle, make it can not fly upward under external force.Although this method is simple and easy to do, because the bonding force between coal dust and moisture is very weak, moisture is easy to evaporation, can not meet permanently effective dust suppression demand, and ability effectively dust suppression of must regularly sprinkling water, water resources consumption is very large.Therefore the coal dust depressor that development of new cheap price and excellent quality is long-acting is very important.
As far back as 20 beginnings of the century, some wetting agents have just been applied in the dust suppression of downhole coal mine exploitation by the country such as Britain.Recent two decades comes, the research of dust-inhibitor develops rapidly abroad, almost there is new Patent Publication every year, wherein more famous have: U.S. Cohex dust adhering agent, the hydrophobic dust-proofing agent of ANTI type in South Africa, Japanese dust inhibitor, the own interior amine type dust adhering agent of USSR (Union of Soviet Socialist Republics), the earth's surface dust-proofing agent of USSR (Union of Soviet Socialist Republics) CIT institute, the dangerous medicament of dust suppression coal dust of Poland.
The investigation and application starting of China in dust-inhibitor is more late, but development rapidly.In late 1970s, the researchist of some research institutions of China just starts relevant research, and to 20 end of the centurys, many achievements are applied for a patent, and the field related to also deepens continuously and widens.Wherein more representational have: a kind of cohesive dust depressor that the people such as Sun Sanxiang develop for the dust from flying of unit train on Datong-Qinhuangdao Railway [, a kind of moist type dust-inhibitor developed for base-material with calcium chloride, magnesium chloride etc. of people's developments such as Jin Longzhe, Li Wei etc. for Railway Coal transport development with lignin sulfonic acid saline taste materials, carry out by polymer monomer a kind of dust-inhibitor that graft modification obtains.
Summary of the invention
The object of this invention is to provide a kind of characteristic that there is good perviousness and adhere to coal body, there is good wind resistance, the anti-performance that drenches with rain, be suitable for Coal Dust Restrainer used in coal storage and transport process and preparation method thereof especially.
Coal Dust Restrainer of the present invention; Be made up of the component of following parts by weight: Xylo-Mucine 15 ~ 18 parts, polyvinyl alcohol fiber 33 ~ 38 parts, 12 ~ 15 parts, calcium oxide, hexamethylenetetramine 6 ~ 8 parts, guar gum 10 ~ 13 parts, sodium polyacrylate 8 ~ 10 parts, polyvinylpolypyrrolidone 3 ~ 5 parts, sodium starch glycolate 18 ~ 20 parts, 80 ~ 95 parts, water.
As optimization, this Coal Dust Restrainer; Be made up of the component of following parts by weight: Xylo-Mucine 16 parts, polyvinyl alcohol fiber 35 parts, 13 parts, calcium oxide, hexamethylenetetramine 6 parts, guar gum 12 parts, sodium polyacrylate 9 parts, polyvinylpolypyrrolidone 4 parts, sodium starch glycolate 19 parts, 90 parts, water.
Prepare the method for this Coal Dust Restrainer, comprise the following steps:
(1) by Xylo-Mucine 16 parts, polyvinyl alcohol fiber 35 parts, join in the water of 50 parts, under 30 DEG C of conditions, with 1000 ~ 1500r/min stir, 20 minutes;
(2) hexamethylenetetramine 6 parts, sodium polyacrylate 9 parts are mixed slowly join in the mixture of step (1) afterwards, stir with 1500 ~ 2000r/min, 20 minutes;
(3) by guar gum 12 parts, polyvinylpolypyrrolidone 4 parts, sodium starch glycolate 19 parts, join in the water of 40 parts, with 800 ~ 1000r/min stir, 10 minutes; Then add 8 parts, calcium oxide, stir with 1000 ~ 1200r/min at 55 ~ 65 DEG C, 5 minutes;
(4) mixture in step (2) is slowly joined, in the mixture in step (3), stir 10 min at 45 ~ 55 DEG C after.
Coal Dust Restrainer of the present invention, but there is the characteristic of good perviousness and adhesion coal body, there is good wind resistance, the anti-performance that drenches with rain, be suitable for especially using in coal storage and transport process, stable performance, easy to use, construction is simple, have no side effect, and can not secondary pollution be caused to material and surrounding environment.
Coal Dust Restrainer of the present invention, the mensuration of viscosity, gets the reagent that 5ml prepares, and measures at 25 DEG C with NDJ-7 type rotational viscosimeter.The mensuration of film formation time, tests according to GBT 13477.5-2002, and records film formation time.Capillary mensuration, adopts the Kr ü ss-k12 program interface tensiometer that Kr ü ss company of Switzerland produces, by the surface tension of hanging the various solution of sheet method constant temperature 25 DEG C test.Related results is in table 1.
Coal cinder takes from colliery, the Jin Meizhao village, Jincheng, crosses 40 mesh standard sieve as laboratory sample after grinding.By dust-inhibitor Coal Dust Restrainer of the present invention, be sprayed onto in coal sample, be positioned in outdoor environment, measure dust suppression rate at set intervals, dust suppression rate=(after test example weight+dust-inhibitor weight)/(before test example weight+dust-inhibitor weight).Experimental data related results is in table 2:
