Igama elithi "wet end chemistry" yigama elikhethekile enqubweni yokwenza iphepha.Imvamisa isetshenziselwa ukuchaza izakhi ezahlukahlukene (njengemicu, amanzi, njll.), izigcwalisi,izithasiselo zamakhemikhali, njll.) umthetho wokusebenzelana nesenzo.
Ngakolunye uhlangothi, i-chemistry-end-end ingasetshenziswa ukuthuthukisa ukugeleza kwamanzi, ukunciphisa ukungena komoya nokuqeda igwebu, ukugcina imishini yephepha ihlanzekile, nokugcina amanzi amhlophe ephansi ezintweni eziqinile;ngakolunye uhlangothi, uma lezi zici ziphuma ekulawuleni, i-chemistry efanayo yokuphela kwamanzi ingenza umshini wephepha usebenze ngendlela engavamile, ukhiqize amabala namabhamuza omoya ephepheni, unciphise ukugeleza kwamanzi, wenze umshini wephepha ungcolile, futhi unciphise ukusebenza kahle kokukhiqiza. .
Ibonakaliswa ngokuyinhloko kulezi zici ezilandelayo:
1) Ukukhipha amanzi e-slurry
Ukudonsa amanzi kuwumsebenzi obalulekile ekusebenzeni komshini wephepha.Izinga lokugeleza kwamanzi kuwebhu yephepha lizothinteka ngokugeleza phakathi kwemicu nemicu naphakathi kwemicu emihle nemicu emihle.Uma ama-flocs akhiwe makhulu futhi ane-porous, i-pulp izoba yi-viscous futhi ivimbele ukudlula kwamanzi, ngaleyo ndlela inciphise ukugeleza kwamanzi.
2) Imvula nokukala
I-sedimentation kanye ne-fouling ngokuvamile kwenzeka lapho i-chemistry ekupheleni okumanzi ingalawuleki, ukusetshenziswa ngokweqile kwezithasiselo zamakhemikhali ezivamile, ukungalingani kwezindleko, ukungahambisani kwamakhemikhali, nokulinganisela kwamakhemikhali okungazinzile, njll.Ukungcola, ziningi izindlela zokuhlanza intlenge nokungcola, kodwa indlela engcono kakhulu ukuthola imbangela yokungalawuleki futhi uyilungise.
3) Ukwakhiwa kwegwebu
Imicu yokhuni iqukethe izinto eziqinisa umoya ku-pulp (futhi izithasiselo ezithile zamakhemikhali zenza okufanayo), zinciphisa ukugeleza kwe-pulp, okubangela ukunamathela kanye negwebu.Uma kwenzeka, indlela engcono kakhulu yokuthola imbangela futhi uyiqede.Uma lokhu kungenakwenzeka, izindlela zemishini nezamakhemikhali ngokuvamile zingasetshenziswa ukukuqeda.Ngalesi sikhathi, indima ye-wet end chemistry incane.
