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, during the storage and railway, highway and ship transportation of harbour coal wharf, power plant, coal yard etc., usually can produce substantial amounts of airborne dust, the most directly threatens the safety produced, also can produce the environment of surrounding and pollute greatly.Therefore the focus of the research of coal dust suppression technology always people's research.The method that suppression coal airborne dust is most commonly used that watering.The Main Function of watering dust suppression is the dry coal dust that wet granulate is tiny so that it is relative density increases, and is bonded to bigger granule, is allowed to can not fly upward under external force.Although this method is simple and easy to do, but owing to the adhesion between coal dust and moisture is the most weak, moisture is easy to evaporation, can not meet permanently effective dust suppression demand, it is necessary to the effectively dust suppression of periodically watering ability, water resource consumption is the biggest.Therefore the coal dust depressor developing novel cheap price and excellent quality long-acting is very important.
As far back as 20 beginnings of the century, some wetting agent have the most 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 suppressant quickly grows abroad, almost there is new Patent Publication every year, wherein relatively famous having: U.S.'s Cohex dust adhering agent, the hydrophobic dust-proofing agent of ANTI type in South Africa, Japan's dust inhibitor, the own interior amine type dust adhering agent of the former Soviet Union, the earth's surface dust-proofing agent of CIT institute of the former Soviet Union, the dust suppression coal dust danger medicament of Poland.
China's research in terms of dust suppressant and application starting ratio are later, but quickly grow.In late 1970s, the research worker of some research institutions of China has just had begun to relevant research, and to 20 end of the centurys, many achievements have been applied for a patent, and the field related to also deepens continuously and widens.Wherein compare and the most representational have: a kind of cohesive dust depressor that Sun Sanxiang et al. develops for the dust from flying of unit train on Datong-Qinhuangdao Railway [, a kind of moist type dust suppressant developed for base material with calcium chloride, magnesium chloride etc. that Jin Longzhe et al. is developed, Li Wei etc. for Railway Coal transport develop with lignosulfonic acid saline taste materials, carry out, by polymer monomer, a kind of dust suppressant that graft modification obtains.
Summary of the invention
It is an object of the invention to provide a kind of characteristic that there is preferable permeability and adhere to coal body, there is preferable wind resistance, the anti-performance that drenches with rain, particularly suitable Coal Dust Restrainer used in coal storage and transport process and preparation method thereof.
Coal Dust Restrainer of the present invention；It is made up of the component of following parts by weight: sodium carboxymethyl cellulose 15～18 parts, vinal 33～38 parts, calcium oxide 12～15 parts, hexamethylenetetramine 6～8 parts, guar gum 10～13 parts, sodium polyacrylate 8～10 parts, polyvinylpolypyrrolidone 3～5 parts, carboxymethyl starch sodium 18～20 parts, water 80～95 parts.
As optimization, this Coal Dust Restrainer；It is made up of the component of following parts by weight: sodium carboxymethyl cellulose 16 parts, vinal 35 parts, calcium oxide 13 parts, hexamethylenetetramine 6 parts, guar gum 12 parts, sodium polyacrylate 9 parts, polyvinylpolypyrrolidone 4 parts, carboxymethyl starch sodium 19 parts, 90 parts of water.
The method preparing this Coal Dust Restrainer, comprises the following steps:
(1) by sodium carboxymethyl cellulose 16 parts, vinal 35 parts, join in the water of 50 parts, under the conditions of 30 DEG C, stir with 1000 ~ 1500r/min, 20 minutes；
(2) it is slowly added in the mixture of step (1) after hexamethylenetetramine 6 parts, 9 parts of mix homogeneously of sodium polyacrylate, stirs with 1500 ~ 2000r/min, 20 minutes；
(3) by guar gum 12 parts, polyvinylpolypyrrolidone 4 parts, carboxymethyl starch sodium 19 parts, join in the water of 40 parts, stir with 800 ~ 1000r/min, 10 minutes；It is subsequently adding calcium oxide 8 parts, stirs with 1000 ~ 1200r/min at 55 ~ 65 DEG C, 5 minutes；
(4) mixture in step (2) is slowly added into, in the mixture in step (3), after stirring 10 min at 45 ~ 55 DEG C,.
Coal Dust Restrainer of the present invention, press down and there is preferable permeability and adhere to the characteristic of coal body, there is preferable wind resistance, the anti-performance that drenches with rain, particularly suitable use in coal storage and transport process, stable performance, easy to use, construction is simple, have no side effect, and material and surrounding are not resulted in secondary pollution.
Coal Dust Restrainer of the present invention, the mensuration of viscosity, take the reagent that 5ml prepares, be measured with NDJ-7 type rotating cylinder viscometer at 25 DEG C.The mensuration of film formation time, tests according to GBT 13477.5-2002, and records film formation time.Capillary mensuration, uses the Kr ü ss-k12 program interface tensiometer that Switzerland Kr ü ss company produces, by the surface tension hanging sheet method constant temperature 25 DEG C and testing various solution.Relevant the results are shown 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 suppressant Coal Dust Restrainer of the present invention, it is sprayed onto in coal sample, is positioned in outdoor environment, measure dust suppression rate, dust suppression rate=(example weight+dust suppressant weight after test)/(example weight+dust suppressant weight before test) at set intervals.Experimental data is relevant the results are shown in Table 2:
