Imikorere no Gutegura Sulfate ya Aluminium mu Gukora Papermaking

Aluminium sulfate(bizwi kandi nka alum cyangwa bauxite) bikunze gukoreshwa nkibimera byo gupima.Ibigize imiti nyamukuru ni aluminium sulfate ifite amazi ya kirisiti 14 ~ 18, naho Al2O3 ni 14 ~ 15%.Aluminium sulfate iroroshye gushonga, kandi igisubizo cyacyo ni acide kandi cyangirika.Umwanda uri muri bauxite ntugomba kuba mwinshi, cyane cyane umunyu wicyuma ntugomba kuba mwinshi, bitabaye ibyo uzavanga imiti hamwe na rosin gum n amarangi, bigira ingaruka kumabara yimpapuro.

Ibipimo ngenderwaho byo gupima bauxite ni: ibirimo alumina birenga 15.7%, ibirimo okiside ya fer iri munsi ya 0.7%, ibirimo amazi adashonga ni munsi ya 0.3%, kandi ntabwo irimo aside ya sulfurike yubusa.

Bauxite igira uruhare runini mugukora impapuro, mbere ya byose ni ugukenera ubunini, kandi byujuje nibindi bisabwa byo gukora impapuro.Igisubizo cya bauxite ni acide, kandi kongeramo byinshi cyangwa bike bauxite bizagira ingaruka kuburyo butaziguye pH agaciro ka slurry kuri net.Nubwo gukora impapuro zirimo guhinduka bitagira aho bibogamiye cyangwa alkaline, uruhare rwa alumina mugukora impapuro ntirushobora kwirengagizwa.

Ubushakashatsi bwerekanye ko kugenzura uδ ubushobozi muguhindura pH agaciro kumurongo birashobora kunoza neza imiyoboro yamazi no kugumana kumurongo wa interineti, kandi irashobora gukoresha neza ifu ya talcum kugirango igenzure inzitizi za resin.Kongera muburyo bukwiye ingano ya bauxite kugirango igabanye pH agaciro ka slurry irashobora kandi kugabanya neza gufatira kwa pulp no kugabanya iherezo-ryangirika ryatewe numusatsi wimpapuro zometse kumutwe.Mubisanzwe byerekana ko iyo habaye impapuro nyinshi ubwoya mu icapiro, ingano ya alumina irashobora kwiyongera uko bikwiye.Nyamara, ingano ya bauxite igomba kugenzurwa neza.Niba umubare ari mwinshi, ntabwo bizatera imyanda gusa, ahubwo bizanatuma impapuro zicika.Kandi biganisha ku kwangirika kwimashini yimpapuro no gutakaza insinga no kumva.Kubwibyo, ingano ya alumina isanzwe igenzurwa no kugenzura agaciro ka pH hagati ya 4.7 na 5.5.

Uburyo bwo gusesa alumina burimo uburyo bwo gushonga bushyushye hamwe nuburyo bukonje bukonje.Icyambere nukwihutisha iseswa rya alumina mugushyushya;icya nyuma nukwihutisha gukwirakwiza no gusesa alumina mugisubizo cyamazi binyuze mukuzenguruka.Ugereranije nuburyo bushyushye bwo gushonga, uburyo bwo gusesa bufite ibyiza byo kuzigama amavuta no kuzamura ibidukikije, kandi nuburyo bwiza bwo gusesa.
