Iko kushandiswa kwePAC mune yepepuru indasitiri

Polandaaluminum chloride (pac) chinhu chakakosha muindasitiri yepepa, ndichiridza basa rakasiyana-siyana mumatanho akasiyana ezvikamu zvakasiyana. Pac ndeyekuwirirana zvinonyanya kushandiswa kusimudzira kuchengetwa kwezvikamu zvakanaka, mafirita, uye machira, nokudaro achivandudza maitiro ese uye kunaka kwepepa kugadzirwa.

Cogulation uye fleculation

Basa rekutanga rePac mupepuru ndiko kuwanda kwaro uye kuwanda mari. Munguva yemapepa ekuita, mvura yakasanganiswa nema cellulose machira kuti aumbe slurry. Iyi slurry ine huwandu hwakakosha hwezvikamu zvakanaka uye zvakanyungudika zvinhu zvinhu zvinoda kubviswa kuti ubudise mapepa emhando yepamusoro. Pac, kana yakawedzerwa kune iyo slurry, neyakaora mhosva isina kunaka pazvikamu zvakamiswa, zvichivatora kuti vatange vafambe pamwe chete mukuunganidza mahombekombe kana mafuro. Kuita uku kwakakosha AIDS mukubviswa kwezvinhu izvi zvakanaka panguva yekudonha kwemaitiro, zvichikonzera mvura yakajeka uye yakavandudzwa fiber kuchengetedza fiber.

Yakavandudzwa Kuchengetwa uye Kudonhedza

Kuchengetwa kwemachira uye mafirita akakosha mune mapepa mapepa sezvairi kukanganisa simba repepa, mavara, uye hunhu hwese. Pac inovandudza kuchengetwa kwezvinhu izvi nekuumba yakakura flocs iyo inogona kuve inochengetwa nyore nyore pane iyo pepa remushini wepepa waya. Izvi hazvingowedzere simba uye kunaka kwepepa asiwo kunoderedza huwandu hwekurera kwezvinhu, zvichitungamira kumabhadharire mari. Uyezve, zvakavandudzwa kudhirowa kufambisa ne pac inoderedza zvirimo mupepa pepa, nekudaro kuderedza simba rinodiwa pakuomesa uye nekuvandudza kugona kwemapepa.

Kuvandudza kwemhando yepepa

Iko kushandiswa kwePAC muPapermaking kunopa zvakanyanya kuvandudzwa kwemhando yemapepa. Nekuvandudza kuchengetwa kweminzvimbo uye mafirita, pac inobatsira mukugadzira pepa nekuumbwa zviri nani, kufanana, uye zvivakwa zvemusoro. Izvi zvinotungamira mukuvandudzwa kwekudhindwa, kutaridzika, uye kutaridzika kwakazara kwepepa, zvichiita kuti ive yakakodzera kudhinda-yakakwirira yekudhinda uye kurongedza mafomu ekurongedza.

Kuderedzwa kweBod uye cod mumapepa emapepa ekurapa

Biochemical Oxixgen Famburedzwa (uye makemikari okisijeni inodiwa (cod) matanho ehuwandu hwehuwandu hwe organic nyaya iripo mumarara anogadzirwa neyepamhepo. Mwero wakakwira weBod uye cod inoratidza yakakwirira mwero wekusvibiswa, izvo zvinogona kukanganisa nharaunda. Pac zvinokwanisika kuderedza mhodzi uye cod mazinga nekukosanako uye kubvisa organic casinnts kubva kumarara. Izvi hazvingabatsire chete mukusangana nemitemo yezvemamiriro ekunze asi zvakare inoderedza mari yekurapa yakabatana neine marara manejimendi.

Mune pfupiso, polandainum chloride yakakosha indasitiri yepepa, ichipa akawanda mabhenefiti anowedzera kugona kweiyo nzira yemapepa uye mhando yechigadzirwa chekupedzisira. Misoro yayo mukubatana, kuwanda, kuwedzeredza kuderedzwa uye kuderedzwa kweBod uye cod, uye nekuvandudzwa kwemhando yepepa kunoita chinhu chakakosha mupepuru yemazuva ano.
