I-Diatomite ayinabo ubuthi futhi ayinabungozi, futhi ukukhangiswa kwayo akunawo umthelela ezingxenyeni ezisebenzayo, ukunambitheka kokudla kanye nephunga lokudla. Ngakho-ke, njengosizo lokuhlunga olusebenzayo futhi oluzinzile, i-diatomite filter aid isetshenziswa kabanzi embonini yokudla. Ngakho-ke, kungabuye kushiwo ukuthi isihlungi se-diatomite sebanga lokudla.
1. Iziphuzo
1. Isiphuzo sekhabhoni
Ikhwalithi yesiraphu eshukela emhlophe eyengezwe ekukhiqizeni iziphuzo ze-carbonated idlala indima ebalulekile kwikhwalithi yemikhiqizo eqediwe. Ngoisiraphu kashukela omhlophe okhiqizwe yi-vulcanization, i-diatomite, kanye nekhabhoni esebenzayo engezwe kusiraphu kusenesikhathi, ingasusa ngempumelelo izinto eziningi ezikushukela omhlophe, njengama-colloids azodala ukugeleza kwesiphuzo futhi aholele ekunambithekeni okungcolile, abambezele ukwanda kokumelana kokuhlunga okubangelwa ukuvinjwa koqweqwe lwe-filter ngokucindezela izinto ezinzima zokuhlunga, ukwehlisa inani lezinto zokuhlunga ngesikhathi esifanayo, futhi ukwandise inani lokuhlunga lombala ngesikhathi esifanayo. isiraphu kashukela omhlophe, ithuthukisa ukucaca kwesiraphu, futhi ekugcineni ihlangabezane nezidingo zokukhiqiza iziphuzo zekhabhoni ezisezingeni eliphezulu.
2. Sula isiphuzo sejusi
Ukuze kuncishiswe imvula kanye ne-flocculent phenomenon ngemva kokugcinwa kweziphuzo zejusi ezicacile, ukhiye uwukuhlunga ngesikhathi senqubo yokukhiqiza. Ekukhiqizeni iziphuzo ezijwayelekile zejusi ezicacile, ijusi iyahlungwa ngemva kwe-enzymolysis nokucaciswa. Kunezindlela ezihlukahlukene zokuhlunga. Ijusi ehlungwe nge-diatomite inezinto eziningi eziqinile kujusi, njengemicu yezitshalo, ama-denatured colloid/amaprotheni, ahlungiwe. Ngaphansi kwesimo sika-6 ° - 8 ° Bx, ukukhanya kungafinyelela ku-60% - 70%, ngezinye izikhathi kuze kufike ku-97%, futhi ukungcola kungaphansi kwe-1.2NTU, kunciphisa kakhulu ukwenzeka kwemvula sekwephuzile kanye nama-floccules.
3. Ama-oligosaccharides
Njengoshukela owengeziwe wokudla, ama-oligosaccharide anezinzuzo ezisobala emikhiqizweni eminingi ye-carbohydrate ngenxa yobumnandi bawo obuthambile, ukusebenza kokunakekelwa kwezempilo, ukuthambisa ukudla, ukusebenza kalula esimweni samanzi kanye nenani eliphansi. Kodwa-ke, enqubweni yokukhiqiza, ukungcola okuningi okuqinile kufanele kususwe, futhi amaprotheni amaningi adinga ukuhlungwa ngemva kokukhangiswa nokukhishwa umbala ngekhabhoni ecushiwe ukuze enze inzika. Phakathi kwazo, ikhabhoni ecushiwe inemisebenzi emibili: i-adsorption kanye nosizo lokuhlunga. Nakuba inqubo yesibili yokushintsha umbala yamukelwa, umphumela wokuhlunga womkhiqizo uhlangabezana nezimfuneko, kodwa umphumela wokukhangiswa nowokususa umbala awulungile noma umphumela wokukhangisa nowokukhipha umbala muhle kodwa kunzima ukuwuhlunga. Ngalesi sikhathi, usizo lokuhlunga lwe-diatomite luyengezwa ukusiza ukuhlunga. Maphakathi nendawo yokuhlungwa okuyisisekelo kokukhishwa kombala nokushintshisana kwe-ion, i-diatomite nekhabhoni ecushiwe kusetshenziswa ngokuhlanganyela ukuhlunga, futhi ukudluliswa kokukhanya kufinyelela ku-99% ngokutholwa okungu-460nm. I-diatomite filter aid ixazulula izinkinga zokuhlunga ezingenhla futhi isusa ukungcola okuningi, Akukhona nje kuphela izinga lomkhiqizo elithuthukisiwe, kodwa futhi inani lekhabhoni ecushiwe liyancishiswa futhi izindleko zokukhiqiza ziyancipha.
