Amagama angundoqo: I-flocculant yokususa umbala, iarhente yokususa umbala, umenzi wearhente yokususa umbala
Kwicandelo lokunyanga amanzi amdaka kwimizi-mveliso,ukususa umbala kwiiflocculantsziphathe “njengogqirha osemgangathweni wamanzi,” ngokukodwa ukuxilonga nokunika amayeza okunyanga amanzi amdaka avela kumashishini ahlukeneyo. Nangona kunjalo, lo gqirha unomgaqo othi: ungaze “unyange” ngaphandle komzi-mveliso wakhe. Kutheni ii-dyeing kunye nee-printing agents zingasetyenziswa ngokuthe ngqo kwiifektri zephepha? Kutheni iifomyula zefektri yokutya zingenakunyanga amanzi amdaka asebenzisa i-electroplating? Emva koku kukho “ikhowudi yomzi-mveliso” yonyango lwamanzi amdaka kwimizi-mveliso.
1. "Umahluko kwi-genetic" yamanzi amdaka kwimizi-mveliso
Amanzi amdaka avela kumashishini ahlukeneyo afana nabantu abaneentlobo ezahlukeneyo zegazi, afuna "igazi elitshintsha umbala elitshintsha umbala." Umzekelo, thabatha ukudaya nokuprinta amanzi amdaka; aqulethe inani elikhulu lezinto eziphilayo ezintsonkothileyo ezifana needayi ze-azo kunye needayi ezisabelayo. Ezi zinto zenza ii-colloids ezitshajiswe kakubi emanzini, zifuna ii-agents ezitshintsha umbala ezithi zithintele umbane kwaye zifezekise ukuguquguquka kombala. Amanzi amdaka e-paper mill aqulunqwe kakhulu yi-lignin kunye ne-cellulose, kwaye iipropati zawo ze-colloidal zahluke kakhulu kwezo zeedayi. Ukunyanzela ukusetyenziswa kwee-agents zokudaya kule meko kufana nokuzama ukunyanga ukwaphuka kwethambo ngamayeza abandayo - umphumo uya kuncipha kakhulu.
Umzekelo oqhelekileyo ngamanzi amdaka okucubungula ukutya. Olu hlobo lwamanzi amdaka lutyebile kwizinto eziphilayo ezifana neproteni kunye nesitatshi, kwaye ixabiso lawo le-pH lidla ngokuba lingathathi cala okanye libe ne-asidi encinci. Ukusebenzisa i-alkaline dyeing decoloring flocculants akuyi kusilela nje kuphela ukususa umbala emanzini amdaka kodwa kuya kutshabalalisa iintsholongwane eziluncedo, okukhokelela ekuweni kweenkqubo zonyango lwebhayoloji ezilandelayo. Oku kufana nokunika i-adrenaline ngempazamo kwisigulana esinesifo seswekile ngelixa ufaka i-insulin - iziphumo azinakucingelwa.
2. "Ukufanisa ngokuchanekileyo" kweeParamitha zoBugcisa
Ixabiso le-pH “liyimigangatho yegolide” yokukhetha ii-flocculants ezisusa umbala. Isityalo seekhemikhali sakha sasebenzisa ngokuthe ngqo i-arhente yokususa umbala emanzini amdaka asebenzisa i-electroplating (pH=2) kumanzi amdaka asebenzisa amayeza (pH=8), nto leyo eyabangela ukungasebenzi ngokupheleleyo kwe-arhente. Oku kungenxa yokuba imeko-bume ene-asidi eninzi iya kubolisa ii-cationic agents, ngelixa imeko-bume ye-alkaline inokubangela ukuna kwee-flocculants ezisusa umbala ze-anionic. Ubushushu bubaluleke ngokulinganayo. Ukusebenzisa ii-agents ezinobushushu obuphantsi kumanzi amdaka anobushushu obuphezulu (60℃) avela kwiifektri zelaphu kuya kubangela ii-floc ezikhululekileyo kunye nokuhla kancinci, njengokusebenzisa umkhenkce ukupheka imbiza eshushu - ukwaphulwa ngokupheleleyo kwemithetho yendalo.
3. "Iinjongo ezimbini" zoQoqosho noKhuseleko
Ukusebenzisa iiarhente kumashishini onke kunokubonakala ngathi kubiza kancinci, kodwa kunokubangela iingozi ezinkulu. Enye inkampani, ngelizama ukonga imali, isebenzise i-flocculant yomzi-mveliso wesikhumba esusa umbala kwi-ofisi yokucoca amanzi amdaka esibhedlele, nto leyo ebangele ukukhutshwa kwesinyithi esinzima kakhulu kunye neentlawulo ezinkulu ezivela kumagunya okusingqongileyo. Nangona iiarhente ezikhethekileyo zibiza kakhulu, ukulinganisa ngokuchanekileyo kunokunciphisa ukusetyenziswa nge-30%, nto leyo ekhokelela ekunciphiseni iindleko zizonke. Okubaluleke ngakumbi, iiarhente ezenzelwe wena zinokuthintela ungcoliseko lwesibini. I-paper mill, emva kokusebenzisa i-flocculant esusa umbala ngokubanzi, yafumana i-COD eninzi kwinkunkuma yayo, yanyanzela ukuba ityale imali kwizibonelelo zonyango eziphambili, ekugqibeleni yaphinda kabini iindleko zayo.
4. "Iingxaki Eziqinileyo" zeMigangatho yoShishino
"Umgangatho wokukhupha ungcoliseko lwamanzi kwiShishini lokuDaya nokuGqiba iLaphu" ufuna ngokucacileyo ukusetyenziswa kwee-flocculants ezikhethekileyo zokususa umbala. Oku akusiyo nje inkcazo yobugcisa kodwa kukwaluxanduva olusemthethweni. Inkampani yokudaya nokuprinta yafakwa kuluhlu olumnyama ziingcali zokusingqongileyo ngokusebenzisa iikhemikhali eziqhelekileyo ngokungekho mthethweni, nto leyo eyabangela ukuba ii-odolo zilahleke ngokuthe ngqo. Ii-flocculants ezithile zoshishino zokususa umbala zihlala ziqinisekisiwe yi-ISO kwaye zineengxelo ezipheleleyo zovavanyo, ngelixa iikhemikhali eziqhelekileyo zihlala zingenawo amaxwebhu okuthobela umthetho, nto leyo ebangela umngcipheko omkhulu kakhulu.
Akukho sisombululo "esifanela bonke" sonyango lwamanzi amdaka kwimizi-mveliso; inyathelo ngalinye linendlela yalo eyahlukileyo. Ukususela kumahluko ekubunjweni nasekusetyenzisweni kwezixhobo zobugcisa ukuya kwiindleko zoqoqosho kunye noxanduva lwezomthetho, yonke into ithetha inyaniso efanayo: ukususa umbala kwiiflocculants ezivela kumashishini ahlukeneyo akufuneki kudityaniswe. Oku akusiyo nje into yokukhetha ubuchwepheshe, kodwa kukwangumcimbi wokuhlonipha imithetho yendalo kunye nokuzibophelela kwindalo esingqongileyo. Kwixesha elizayo, njengoko ukwahlulwahlulwa kwemizi-mveliso kuphucuka ngakumbi, ukwenza ngokwezifiso kunye nobuchwephesha kuya kuba yindlela yokunyanga amanzi amdaka.
