Izithasiselo zamakhemikhali eziningi zokwenza iphepha zivame ukusetshenziswa embonini yamaphepha, futhi izinhlobo zazo zibanzi futhi zisetshenziswa kabanzi, futhi imisebenzi yazo ibonakala ikakhulukazi kulezi zici ezilandelayo:

01 Thuthukisa ukusebenza kahle kokukhiqiza

Ukuze kuthuthukiswe isivinini sokukhipha amanzi ekugcineni okumanzi komshini wephepha futhi kusheshiswe ukuhwamuka kwamanzi ku-cadre, usizo lokuhlunga lungangezwa ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza. Ukuze wenze i-pulp ibala ngokulinganayo futhi iqine, i-mordant ne-dispersant ingangezwa. Lapho wenza usayizi we-rosin, ukwengeza i-synergist kungathuthukisa umphumela wokulinganisa. Ngaphezu kwalokho, iphepha likadoti eligaywe kabusha liqukethe uyinki nezinye izinto, futhi ama-aste paper deinking agents angengezwa ukuze kukhiqizwe i-pulp ehlanzekile.

02 Thuthukisa ikhwalithi futhi unikeze izinto ezikhethekile zephepha

Isibonelo, iphepha lesikhwama sikasimende lidinga amandla aphezulu kanye nokungena kahle, futhi izinga lokushaya alikwazi ukuba phezulu lapho lishaya. Ukuze uthuthukise amandla ephepha, ama-ejenti wamandla omile avame ukungezwa. Ama-napkins namathawula wephepha adinga ukuthamba njengokotini, futhi ama-wipes awakwazi ukuxubha, futhi kuzongezwa isithambisa samaphepha.

03 Nciphisa imfucuza futhi wonge izinto ezingavuthiwe

Isibonelo, ukungeza ama-retention agents nama-flocculants ku-pulp kungathuthukisa izinga lokugcinwa kwezigcwalisi nemicu emihle, kunciphise ukulahlekelwa, konga izinto zokusetshenziswa, futhi kunciphise ukungcoliswa kwamanzi angcolile.

04 Susa izithiyo zokukhiqiza

Ehlobo, udaka luvame ukuba khona emathangeni odaka, amathange anezikhala, noma amapayipi amanzi amhlophe futhi abole, okudala izithiyo ekukhiqizeni. Manje kunezinhlobonhlobo zokusebenza kahle okuphezulu, ubuthi obuphansi, izilondolozi ezizibolayo, zingabulala amabhaktheriya kanye ne-anti-corrosion, ngeke kubangele ukungcola.

Uma i-pulp ingahlanzwa futhi ixutshwe nomoya, izokhiqiza igwebu kanye ne-pulp elintantayo, eliyingozi kukhwalithi nokusebenza kwephepha. Ukuze kuqedwe ukulimala kwegwebu, i-defoamer ne-degassing ejenti ingasetshenziswa.

05 Thuthukisa ukusebenza kokukhiqiza

Ukusetshenziswa kwe-blanket cleaner kungasheshisa ukuwashwa kwengubo futhi kugcine ingubo ihlanzekile. Ama-Adhesives avame ukungezwa embotsheni ukuze kuthuthukiswe ikhwalithi yephepha eliboshwe. Ukwengezwa kwe-dispersant kunganciphisa i-viscosity yokugqoka, kukhuthaze ukusebenza kokukhiqiza futhi kwenze umfaniswano wokugqoka. Ukwengezwa kwe-adhesive kungathuthukisa ukumelana kwamanzi kwe-coating.
