Ukuphuhliswa kunye nokusetyenziswa kwee-pigments zendalo kuye kwaba yinto exhalabisayo ngokubanzi kubasebenzi besayensi kunye nezobuchwepheshe kumashishini ahlukeneyo.Abantu bazama ukufumana i-pigments yendalo kwizilwanyana ezahlukeneyo kunye nezityalo kunye nokuphonononga imisebenzi yabo ye-physiological ukunciphisa kunye nokusombulula iingxaki ezahlukeneyo ezibangelwa yi-pigment synthetic.Inkqubo yokukhutshwa kwee-pigments zendalo ibuye ihlaziywe ngokukhawuleza, kwaye ngoku iteknoloji yokwahlula i-membrane iye yaba yenye yeendlela eziphambili zokukhutshwa kwe-pigment yendalo.
Ukwahlula kweMembrane kubandakanya iinkqubo ezine eziphambili ze-membrane ye-cross-flow: i-microfiltration MF, i-ultrafiltration UF, i-nanofiltration NF, kunye ne-reverse osmosis RO.Ukwahlula kunye nokugcinwa kokusebenza kwee-membrane ezahlukeneyo zihlukaniswa nobukhulu be-pore kunye ne-molecular weight cut-off ye-membrane.Itekhnoloji yokuhluza iMembrane isetyenziswe kakhulu kumayeza, idayi, ukutya kunye namashishini okulungisa ijusi kumazwe aphuhlileyo asentshona.Ukusetyenziswa kweteknoloji yokucoca i-membrane ekuveliseni i-pigments yendalo kunokuphucula imveliso ye-pigments yendalo, ukususa idayi yesibini kunye nokungcola okuncinci kwee-molecular, kunye nokunciphisa iindleko zokuvelisa.Ngaphandle kwamathandabuzo, itekhnoloji ye-membrane idlale indima ebalulekileyo ekuhlanganiseni imeko yala mashishini kushishino lwe-pigment yendalo, kwaye isetyenziswe ngempumelelo kwishishini elithile lasekhaya lokuvelisa i-pigment yendalo.
Kwinkqubo yokuvelisa i-pigment, ngakumbi kulwelo lokutya olunoxinzelelo oluphantsi oluqinileyo, xa kuthelekiswa nendlela yokuhluza ngokupheleleyo, isixhobo sokwahlula inwebu sisebenzisa indlela yokucoca i-cross-flow kunciphisa kakhulu ukuvaleka komphezulu we-membrane ngenxa ye-cross-flow izinto eziphathekayo kunye nolwelo, ezinokuphucula izinga lokuhluza.izinga.Ukongeza, isixhobo se-membrane sinokwenziwa inzala ngaxeshanye, kwaye akukho mfuneko yokuseta enye inzala kunye nenkqubo yokucoca, ukuze kufezekiswe injongo yokwenza lula inkqubo kunye nokunciphisa iindleko.
1. Itekhnoloji ye-Microfiltration ingahluza amacandelo anganyibilikiyo kwisicatshulwa se-pigment yendalo kunye nokungcola okunobunzima bemolekyuli obungaphezulu kwamakhulu aliqela amawaka, njengestatshi, i-cellulose, itshungama yemifuno, i-macromolecular tannins, iiproteni ze-macromolecular kunye nobunye ukungcola.
2. I-Ultrafiltration isetyenziselwa ukucaciswa kwee-pigments eziveliswa ngokuvutshelwa, endaweni yendlela yokucaciswa kwendabuko, inokuthintela ngokufanelekileyo ukumiswa kwe-macromolecular kunye neeprotheni, kwaye ivumele isicatshulwa se-pigment esicacileyo ukuba singene kwi-membrane kwaye singene kwicala le-permeate.
3. I-Nanofiltration isetyenziselwa ukugxininiswa / ukuchithwa kwamanzi kwi-pigment kwiqondo lokushisa, ngokuqhelekileyo ngokudibanisa okanye endaweni ye-evaporators.Ngexesha lokuhluza, amanzi kunye nokungcola okuncinci kwe-molecule (njenge-citrinin kwi-monascus) idlula kwi-membrane ngelixa i-pigment components igcinwa kwaye igxininiswe.
Kwiminyaka yakutshanje, uphuhliso kunye nokusetyenziswa kwee-pigments zendalo ziphuhliswe ngokukhawuleza.Nangona kunjalo, uphando kunye nokuphuhliswa kwee-pigments zendalo zisajongene neengxaki ezininzi: izinga lokukhutshwa kwee-pigments zendalo liphantsi, kwaye ixabiso liphezulu;ukuzinza kwe-pigment akubi, kwaye kuvakalelwa kwiimeko zangaphandle ezifana nokukhanya nokushisa;kukho iintlobo ezininzi, kwaye uphando kunye nophuhliso zithe saa.Ngophuhliso kunye nokuphuculwa kweteknoloji yokwahlula i-membrane, kukholelwa ukuba iya kudlala indima ebaluleke kakhulu ekukhutshweni kwee-pigments zendalo.Kwixesha elizayo, indibaniselwano yetekhnoloji yokwahlula i-membrane yolwelo kunye neetekhnoloji ezintsha ezahlukeneyo ziya kwandisa imveliso yemibala yendalo kunye nokuphucula umgangatho wemveliso, ukunciphisa iindleko zokuvelisa.
