Nigute ushobora kuzamura umusaruro mubikorwa byinganda zikora impapuro binyuze muri polyacrylamide

Polyacrylamideni inyongera ikoreshwa cyane munganda zimpapuro. Polyacrylamide (PAM), nka polymer ibora amazi, ifite flocculation nziza, kubyimba, gutatanya nibindi bintu. Bizakoreshwa muburyo butandukanye hamwe nibikorwa bitandukanye. Mu nganda zikora impapuro, PAM igira uruhare rukomeye. Byazanye inyungu zubukungu mu nganda zikora impapuro zitezimbere imitunganyirize no kongera imikorere yimashini zimpapuro. Iyi ngingo izaganira ku buryo burambuye ikoreshwa rya polyacrylamide mu gukora impapuro n'ingaruka zabyo mu kuzamura umusaruro.

Ibintu shingiro nibikorwa bya polyacrylamide

Polyacrylamide ni polymer ndende cyane ishobora kugabanywamo ubwoko bwa nonionic, anionic, cationic na amphoteric ukurikije imiterere yabyo. Iyo PAM ishonga mumazi, hamwe na molekulire yayo miremire ituma igira ibikorwa byiza nka flocculation, kubyimba, ubufasha bwo kugumana, hamwe nubufasha bwo kuyungurura. Mu nganda zimpapuro, polyacrylamide ikoreshwa cyane mubice bikurikira:

1. Imfashanyo yo kugumana:

Molekile ya PAM ifite urunigi rurerure kandi irashobora kwamamazwa hejuru ya fibre hamwe nuwuzuza kugirango ibe ibiraro. Gutyo, kuzamura igipimo cyo kugumya kuzuza na fibre kurubuga rwimpapuro. Kugabanya igihombo cya fibre mumazi yera kandi ugabanye gutakaza ibikoresho bibisi. Mugukomeza igipimo cyo kugumana ibyuzuye na fibre, impapuro zumubiri zimpapuro nkubworoherane, gucapwa, nimbaraga zirashobora kunozwa.

2. Akayunguruzo:

Kunoza imikorere yamazi ya pulp, kwihutisha uburyo bwo kuyungurura amazi no kugabanya gukoresha ingufu.

3. Flocculant:

Kwihutisha umwuma wa sludge: PAM irashobora guhinduranya neza fibre ntoya, yuzuza nibindi bintu byahagaritswe kugirango ibe ibice binini, byihutishe gutuza no kubura umwuma, kandi bigabanya amafaranga yo kuvura imyanda.

Kunoza ubwiza bw’amazi: PAM irashobora gukuraho neza ibintu byahagaritswe n’ibinyabuzima mu mazi y’amazi, kugabanya BOD na COD mu mazi y’amazi, kuzamura ubwiza bw’amazi, no kugabanya umwanda w’ibidukikije.

4. Gutatana:

Irinde fibre agglomeration: PAM irashobora gukumira neza fibl agglomeration muri pulp, kunoza uburinganire bwimbuto, no kuzamura ubwiza bwimpapuro.

Gukoresha polyacrylamide mubuhanga bwo gukora impapuro

1. Icyiciro cyo gutegura

Mugihe cyo gutegura pulp, fibre nziza hamwe nuwuzuza bitakara byoroshye namazi yanduye, bigatera imyanda yumwanda hamwe nibidukikije. Gukoresha cationic polyacrylamide nkimfashanyo yo kugumana birashobora gufata neza no gutunganya fibre ntoya hamwe nuwuzuza muri pulp binyuze mukutabogama kwishyurwa no kubiraro. Ibi ntibigabanya gusa gutakaza fibre, ahubwo binagabanya imizigo yo gutunganya imyanda.

2. Imashini yimpapuro zuzuye sisitemu yanyuma

Muri mashini yimpapuro zuzuye sisitemu, umwuma wihuse nurufunguzo rwo kuzamura umusaruro. Anionic cyangwa nonionic polyacrylamide irashobora gukoreshwa nkimfashanyo yo kuyungurura kugirango byorohereze amazi guhunga imiyoboro ya fibre mugutezimbere flokculation hagati ya fibre. Iyi nzira igabanya cyane igihe cyo kubura amazi mugihe igabanya ingufu zikoreshwa mugihe cyumye.

3. Icyiciro cyo gukora impapuro

Nkikwirakwiza, polyacrylamide irashobora gukumira neza fibre ya fibre no kunoza uburinganire nuburinganire bwimpapuro. Muguhitamo witonze uburemere bwa molekuline hamwe nubucucike bwa PAM, ibintu bifatika byimpapuro zuzuye, nkimbaraga zinguvu nimbaraga zamarira, nabyo birashobora kuba byiza. Byongeye kandi, polyacrylamide irashobora kandi kunoza ingaruka zo gutwikira impapuro zometseho kandi bigatuma imikorere yo gucapa neza.

Ibyiza byingenzi bya polyacrylamide mugutezimbere umusaruro

1. Kugabanya igihombo cyibikoresho

Gukoresha infashanyo yo kugumana bizamura cyane igipimo cyo kugumana fibre nziza hamwe nuwuzuza muri pulp, bigabanya gukoresha ibikoresho fatizo, kandi bizigama byimazeyo umusaruro.

2. Wihutishe inzira yo kubura umwuma

Kwinjiza infashanyo zungurura bituma inzira yo kuvoma ikora neza, bityo byongera umuvuduko wimashini yimpapuro no kugabanya umusaruro. Ibi ntabwo byongera ubushobozi bwumusaruro wonyine, ahubwo binagabanya gukoresha ingufu.

3. Kugabanya umuvuduko wo gutunganya amazi mabi

Mugutezimbere ingaruka ziterwa na flocculation, polyacrylamide irashobora kugabanya neza ibiri mubintu byahagaritswe mumazi y’amazi, bikagabanya imizigo y’ibikorwa byo gutunganya imyanda biva mu isoko kandi bikagabanya amafaranga yo kurengera ibidukikije by’inganda.

4. Kunoza ireme ryimpapuro

Imikoreshereze ikwirakwiza ituma fibre ikwirakwizwa yimpapuro irushaho kuba imwe, itezimbere cyane imiterere yumubiri nu iyerekwa ryimpapuro, kandi ikazamura isoko ryisoko ryibicuruzwa.

Ibintu bigira ingaruka kumikoreshereze ya polyacrylamide

Kugirango utange umukino wuzuye kumikorere ya polyacrylamide, ibintu bikurikira bigomba kwibandaho:

1. Guhitamo icyitegererezo cya PAM

Uburyo butandukanye bwo gukora impapuro nubwoko bwimpapuro bifite ibisabwa bitandukanye kuburemere bwa molekile hamwe nubucucike bwa PAM. Uburemere buke bwa molekile PAM ikwiranye na flocculation hamwe nayungurura, mugihe uburemere buke bwa molekile PAM ikwiranye no gutatanya.

2. Ongeramo umubare no kongera uburyo

Umubare wa PAM wongeyeho ugomba kugenzurwa neza. Umubare munini urashobora gutera ingaruka mbi, nko guhindura imikorere ya dehidrasi cyangwa kongera umusaruro. Muri icyo gihe, uburyo bwo kongeramo uburyo butandukanye bwakagombye gukoreshwa kugirango hirindwe guterana kwaho bigira ingaruka.

3. Ibikorwa

Ubushyuhe, pH nuburyo bwamazi byose bigira ingaruka kumikorere ya PAM. Kurugero, cationic PAM ikora neza mubutabogamye kugeza acide nkeya, mugihe anionic PAM ibereye ibidukikije bya alkaline.

Nka nyongeramusaruro myinshi mubikorwa byinganda zikora impapuro, polyacrylamide igira uruhare runini mugutezimbere umusaruro, kugabanya ibiciro byumusaruro no kuzamura ubwiza bwibicuruzwa hamwe na flocculation nziza, kubika, kuyungurura no gukwirakwiza. Mubikorwa bifatika, ibigo bigomba guhitamo neza no guhindura uburyo bwo gukoresha PAM ukurikije imiterere yabyo kandi ikeneye kugera ku nyungu nziza zubukungu n’ibidukikije.
