In unyango lwamanzi amdaka kwimizi-mveliso, ukususwa kwezinto eziqinileyo ezixhonyiweyo likhonkco eliphambili. Oku akuncedi nje ekuphuculeni umgangatho wamanzi, kodwa kunciphisa ukuguguleka kwezixhobo kunye nokuvaleka kwazo. Okwangoku, iindlela zokususa izinto eziqinileyo ezixhonyiweyo ziquka ikakhulu ukugalelwa kwenkunkuma, ukuhluzwa, ukudada kunye nokudumba. Phakathi kwazo, indlela yokudumba isetyenziswa kakhulu ngenxa yokusebenza kwayo kakuhle kunye noqoqosho. Kule ndlela, i-polymer ebizwa ngokuba yiPolyDADMAC idlala indima ebalulekileyo.
I-PolyDADMAC, egama layo lipheleleyo yi-Poly diallyl dimethyl ammonium chloride, yi-polymer ephezulu yeemolekyuli. Yenziwa ngokuyintloko ngokupholisha i-diallyldimethylammonium chloride monomer ngokusebenzisa i-chain growth polymerization. Le mpendulo ye-polymerization idla ngokwenziwa phantsi kwe-catalysis ye-asidi okanye ityuwa, kwaye i-polymer yesakhiwo esithe ngqo ingafunyanwa. Idla ngokuba lulwelo olutyheli okanye umgubo omhlophe ukuya kotyheli okanye iigranules. Inonyibiliko oluhle kwaye ingasasazwa ngokulinganayo kwizisombululo zamanzi.
I-PolyDADMACinobunzima obukhulu bokutshaja kwaye idla ngokusebenza njenge-cationic polymer. Oku kuthetha ukuba inokufunxa izinto eziqinileyo ezixhonyiweyo ezitshajiweyo kakubi kunye namasuntswana e-colloidal emanzini ukuze zenze ii-flocs ezinkulu, ngaloo ndlela ifezekisa ukususwa okusebenzayo kwezinto eziqinileyo ezixhonyiweyo. I-PolyDAMAC idla ngokusetyenziswa njenge-flocculant kunye ne-coagulant kwaye isetyenziswa kakhulu kwiindawo ezahlukeneyo zonyango lwamanzi, kubandakanya unyango lwamanzi amdaka kwimizi-mveliso kunye nonyango lwamanzi amdaka asezidolophini. Ingenza ngokukhawuleza ii-flocs ezinkulu nezixineneyo emanzini amdaka kwaye isuse ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo, ii-ion zesinyithi esinzima kunye nongcoliseko lwezinto eziphilayo.
Ekunyangweni kwamanzi amdaka avela kwiipulp kunye neemill zephepha, indlela yokusebenza yePolyDADMAC ibonakaliswa kakhulu kwezi zinto zilandelayo:
Ukungatshaji: Ngenxa yokuba iPolyDADMAC inobunzima obukhulu bokutshaja, inokufunxa ngokukhawuleza izinto eziqinileyo ezitshajiweyo kakubi kunye nee-colloidal particles, nto leyo ebangela ukuba zilahlekelwe buzinzo ngokungatshaji, zize zihlangane zenze ii-flocs zee-particles ezinkulu.
Isenzo sokutshayela: Njengoko i-floc isenziwa, iya kutsala izinto eziqinileyo ezixhonyiweyo kunye namasuntswana e-colloidal emanzini amdaka ukuya kwi-floc, ifezekise ukwahlukana kolwelo oluqinileyo ngesenzo somzimba.
Isiphumo sokubamba nge-net: Iipolymers ezineemolekyuli eziphezulu zinokwenza isakhiwo senethiwekhi esixineneyo, zibambe izinto eziqinileyo ezixhonyiweyo kunye namaqhekeza e-colloidal kuyo njengenethi yokuloba, ngaloo ndlela zifezekisa ukwahlukana okusebenzayo.
Xa kuthelekiswa nezinye iindlela zonyango lwamanzi amdaka, ukusebenzisa iPolyDADMAC ukunyanga amanzi amdaka epulp kunye nephepha lokugaya amanzi kunezi nzuzo zilandelayo:
Uxinano olukhulu lwe-charge: Uxinano olukhulu lwe-PolyDAMAC luyenza ikwazi ukufunxa izinto eziqinileyo ezitshajiweyo kunye nee-colloidal particles ngempumelelo, nto leyo ephucula ukusebenza kakuhle konyango.
Ukuguquguquka okuqinileyo: I-PolyDADMAC inemiphumo emihle yonyango kwiintlobo ezahlukeneyo zamanzi amdaka e-pulp kunye nephepha kwaye ayichaphazeleki kukutshintshatshintsha komgangatho wamanzi.
Ukusebenza kakuhle kunye nokusetyenziswa okuphantsi: Ukusebenzisa iPolyDADMAC njengeI-Flocculantkunye ne-coagulant zinokunciphisa kakhulu umthamo weekhemikhali, ngelixa ziphucula ukusebenza kakuhle konyango kwaye zinciphisa iindleko zokusebenza.
Inobuhlobo nokusingqongileyo: I-PolyDADMAC yi-cationic polymer. I-floc eveliswa emva kokusetyenziswa ayiboli lula ibe zizinto eziyingozi kwaye inobuhlobo nokusingqongileyo.
Ukuqukumbela, iPolyDADMAC, njengeI-Polymer ephezulu yeMolekyuli, ineengenelo zokusebenza kakuhle, ukusetyenziswa okuphantsi, kunye nobuhlobo nokusingqongileyo, kwaye idlala indima ebalulekileyo ekunyangeni amanzi amdaka avela kwiifektri zepulp kunye nephepha. Ngexesha apho umkhwa wokukhusela okusingqongileyo kunzima ukuwuxhathisa, iPolyDADMAC yimveliso edumileyo yeekhemikhali ehlangabezana neempawu zeemveliso ezinobuhlobo nokusingqongileyo.
