Activated kabhoni, dzimwe nguva inonzi activated charcoal, yakasarudzika adsorbent inokosheswa neyakaomesesa chimiro chayo chinoibvumira kubata nemazvo kubata uye kubata zvinhu.
Inoshandiswa zvakanyanya mukati mehuwandu hwemaindasitiri kubvisa zvisingadiwe kubva kune zvinwiwa kana magasi, activated kabhoni inogona kuiswa kune isingaverengeki nhamba yezvishandiso zvinoda kubviswa kwezvinosvibisa kana zvinhu zvisingadiwe, kubva mukucheneswa kwemvura nemhepo, kugadzirisa ivhu, uye kunyangwe goridhe. kupora.
Inopihwa pano muchidimbu pane izvi zvinoshamisa zvakasiyana-siyana zvinhu.
CHII CHINOITWA CARBON?
Activated kabhoni ndeye kabhoni-yakavakirwa zvinhu iyo yakagadziriswa kuti iwedzere ayo adsorptive zvimiro, ichiburitsa yepamusoro adsorbent zvinhu.
Activated kabhoni inoshamisira inoyevedza pore chimiro chinoita kuti ive nepamusoro penzvimbo yekubata nekubata zvinhu, uye inogona kugadzirwa kubva kune akati wandei kabhoni-rich organic zvinhu, zvinosanganisira:
Makokonati matehwe
Wood
Marasha
Peat
Uye zvimwe…
Zvichienderana nekwakabva zvinhu, uye nzira dzekugadzirisa dzinoshandiswa kugadzira kabhoni yakabatidzwa, humiro nemakemikari echigadzirwa chekupedzisira anogona kusiyana zvakanyanya.² Izvi zvinogadzira matrix emukana wekusiyana kwemakabhoni anogadzirwa nekutengesa, nemazana emhando dziripo. Nekuda kweizvi, makabhoni anogadzirwa anogadzirwa ane hunyanzvi kuti awane mibairo yakanaka kune yakapihwa application.
Pasinei nekusiyana kwakadaro, kune marudzi matatu makuru eakagadzirwa kabhoni anogadzirwa:
Powdered Activated Carbon (PAC)
Powdered activated carbons kazhinji inowira muchikamu chehukuru hwe5 kusvika 150 Å, paine mamwe masaizi ekunze aripo. PAC's inowanzo shandiswa mune yemvura-chikamu adsorption application uye inopa yakaderedzwa mitengo yekugadzirisa uye kuchinjika mukushanda.
Granular Activated Carbon (GAC)
Granular activated carbons inowanzosiyana muhukuru hwe 0.2 mm kusvika 5 mm uye inogona kushandiswa mune zvese gasi uye mvura chikamu maapplication. MaGAC anozivikanwa nekuti anopa kubata kwakachena uye anogara kwenguva refu kupfuura maPAC.
Pamusoro pezvo, vanopa simba rakavandudzwa (kuoma) uye rinogona kuvandudzwa uye kushandiswa zvakare.
Extruded Activated Carbon (EAC)
Extruded activated carbons chigadzirwa checylindrical pellet chinotangira pakukura kubva pa1 mm kusvika pa5 mm. Inowanzo shandiswa mune gasi chikamu chekuita, EACs inorema-basa activated kabhoni semhedzisiro ye extrusion process.
Mamwe Marudzi
Mamwe marudzi e activated carbon anosanganisira:
Bead Activated Carbon
Impregnated Carbon
Polymer Coated Carbon
Activated Carbon Micheka
Activated Carbon Fibers
PROPERTIES OF ACTIVATED CARBON
Paunenge uchisarudza iyo activated kabhoni yeimwe application, akasiyana siyana maitiro anofanirwa kutariswa:
Pore Structure
Mamiriro epore eakabatidzwa kabhoni anosiyana uye zvinonyanya kukonzerwa nekwakabva zvinhu uye nzira yekugadzira.¹ Maumbirwo epore, pamwe chete nemasimba anoyevedza, ndiwo anotendera kuti adsorption iitike.
Kuoma/kubvongodzwa
Kuomarara/abrasion zvakare chinhu chakakosha pakusarudza. Mazhinji maapplication anozoda iyo activated kabhoni kuti ive yakakwira particle simba uye kuramba kune attrition (kuparara kwezvinhu kuita faindi). Activated carbon inogadzirwa kubva kukokonati shells ine yakanyanya kuoma kwe activated carbons.4
Adsorptive Properties
Iko kunyura kweiyo activated kabhoni kunosanganisira akati wandei maitiro, anosanganisira adsorptive kugona, mwero we adsorption, uye kushanda kwese kwe activated carbon.4
Zvichienderana nekushandiswa (mvura kana gasi), zvinhu izvi zvinogona kuratidzwa nezvinhu zvakawanda, kusanganisira nhamba yeiodine, nzvimbo, uye Carbon Tetrachloride Activity (CTC).4
Apparent Density
Kunyange zvazvo dhizaini inooneka isingakanganisi adsorption per unit uremu, ichakanganisa adsorption per unit volume.4
Unyoro
Sezvineiwo, huwandu hwehunyoro hwemuviri huri mukati meiyo activated kabhoni hunofanirwa kuwira mukati me3-6%.4
Ash Content
Iyo ash yemukati yeakabatidzwa kabhoni chiyero cheinert, amorphous, inorganic, uye isinga shandiswe chikamu chechinhu. Madota emukati anozove akadzikira sezvinobvira, sezvo kunaka kweiyo activated kabhoni kunowedzera sezvo madota anodzikira. 4
