I-pulp eluhlaza iqukethe inani elincomekayo le-lignin nokunye ukuguquguquka kombala, kufanele ifakwe bleach I-pulp eluhlaza iqukethe inani elincomekayo le-lignin nokunye ukuguquguquka kombala, kufanele ifakwe bleach ukuze kukhiqizwe amaphepha anombala okhanyayo noma amhlophe ancanyelwa imikhiqizo eminingi.Amafayibha aphinde ahlotshiswe ngokuncibilikisa i-lignin eyengeziwe ku-cellulose ngokusebenzisa i-chlorination kanye ne-oxidation.I-Sodium Hydroxide, i-alkali eqinile isetshenziselwa ukukhipha i-lignin encibilikisiwe emanzini.Amakhemikhali asetshenziselwa ukushibilika kwamapuphu emishini achitha ngokukhetha ukungcola okunemibala kodwa ashiye i-lignin kanye nezinto ze-cellulosic ziphelele, njenge-sodium bisulfite, i-sodium noma i-zinc hydrosulfite, i-calcium noma i-sodium hypochlorite, i-hydrogen noma i-sodium peroxide, kanye ne-Sulfur Dioxide-Borol Process.
Ukuze kuqinisekiswe ukuthi ubumhlophe bephepha bulingana futhi bulungile, izithasiselo ezahlukene, ama-disperants kanye nama-bleaching agents kufanele afakwe.Njengokusetshenziswa kwezithasiselo embonini yokudla, lezi zengezo zinezinga lokugeleza elincane futhi zigqwala kakhulu.
Inzuzo:
?Ingacushwa ngohlu lwezinto ukuze ihambisane nezidingo zenqubo
?Idayamitha egcwele ngaphandle kokwehla kwengcindezi kuyo yonke imitha
?Izilinganiso ezizinzile, ezinembile ezimelela ukugeleza kwangempela.
Inselelo:
?Izinga lokugeleza lincane, futhi isignali yokuphumayo izoshintshashintsha kakhulu.
?Indlela edla kakhulu izoba nomthelela empilweni yesevisi
I-Lining: Iningi labo likhetha umugqa we-PTFE kanye nomugqa we-PFA.
I-Electrode: I-Ta/Pt ikhethwe ngokuya ngezakhiwo ezihlukene zoketshezi
Naka ngokukhethekile ukugxila lapho ufaka i-electromagnetic flowmeter enezinga elincane.
I-electrode engalungile kanye nezinto zolayini, ukunganeliseki kwepayipi, ubude obanele bepayipi eliqondile, nokungaqondani kahle ngesikhathi sokufakwa kobubanzi obuncane kuvame ukuba yizici eziyinhloko ezenza i-flowmeter kagesi yehluleke ukusebenza ngendlela evamile.
