Indima Emangalisayo Ye-Polyacrylamide Ensimini Yokwenza Amaphepha

I-Polyacrylamideigama elijwayelekile lama-homopolymer e-acrylamide noma ama-copolymer namanye ama-monomers. Lingenye yama-polymer ancibilika emanzini asetshenziswa kakhulu. I-Polyacrylamide ikhona ngesimo sama-granule amhlophe futhi ingahlukaniswa ngezinhlobo ezine: i-non-ionic, i-anionic, i-cationic, kanye ne-amphoteric ionic.

Ukusetshenziswa kwePolyacrylamide Ensimini Yokwenza Iphepha

Inqubo yokwenza amaphepha inezigaba eziningana, okuhlanganisa ukugaya, ukuhlola, ukuhlanza, ukucwenga, nokwakha. Phakathi nalezi zinqubo, kukhiqizwa ukungcola okuhlukahlukene okufana nemicu, izigcwalisi, kanye nezinhlawulo. Uma lokhu kungcola kungasuswa kahle ku-pulp, kungaholela ezinkingeni ezifana nokungakhiphi kahle amanzi kanye nokuqina kwephepha okuphansi. I-Polyacrylamide isetshenziswa kakhulu njenge-dispersant, i-retention aid, i-drainage aid, i-flocculant, kanye ne-size agent enqubweni yokwenza amaphepha.

Ⅰ. Isihlanzisi

Ukwengeza i-polyacrylamide dispersant ngesikhathi senqubo yokwenza iphepha kungavimbela ngempumelelo ukuhlangana kwemicu futhi kuthuthukise ukufana kwephepha. Inani eliphansi lokwengeza lingakhuthaza ukusabalala okuhle kwemicu yokwenza iphepha futhi lifinyelele umphumela omuhle kakhulu wokwenza iphepha. Kungathuthukisa futhi ukufana kwe-pulp kanye nobumnene bephepha, futhi kuthuthukise izakhiwo zamandla ephepha. Lifanele imikhiqizo ehlukahlukene yamaphepha asekhaya njengephepha langasese, ama-napkin, izicubu zobuso, namanye amaphepha amancane. Kwezinye izindawo zokugaya amaphepha, lingathatha indawo ye-Polyethylene Oxide (PEO) ngokuphelele.

Ⅱ. Usizo Lokugcina

I-PAM ivame ukusetshenziswa njengosizo lokugcina izinto embonini yokwenza amaphepha ukuze kwandiswe izinga lokugcina izinto ezicutshungulwayo futhi kuncishiswe ukuthuthwa kwendle. Isimiso sayo esisebenzayo ukwakha ama-floc amakhulu anezinhlayiya ezincane, ezingasuswa kalula ku-pulp ngokuhluzwa noma ngokufakwa kwenhlabathi.

Ⅲ. Usizo Lokukhipha Amanzi

I-PAM ingasebenza futhi njengosizo lokukhipha amanzi enkambisweni yokwenza iphepha. Yandisa izinga lokukhipha amanzi, okwenza kube lula ukusula amanzi ephepheni ngokushesha nangokuphumelelayo emshinini wephepha. Lokhu kusiza ukwandisa isivinini sokukhiqiza nokunciphisa ukusetshenziswa kwamandla ngokunciphisa isikhathi sokomisa esidingekayo ephepheni.

Ⅳ. I-ejenti Yokulinganisa

Kwezinye izimo, i-polyacrylamide isetshenziswa njenge-ejenti yokulinganisa ekwenzeni iphepha ukulawula ukungena kwamanzi nezinye izinto eziwuketshezi ephepheni lephepha. Lokhu kusiza ekufezeni izakhiwo ezifiselekayo njengokumelana namanzi kanye nokubamba uyinki, ikakhulukazi ekusetshenzisweni lapho iphepha lidinga ukumelana nomswakama noma izinqubo zokunyathelisa.

Ⅴ. I-Flocculant

Ngesikhathi senqubo yokwelapha amanzi amdaka ezindaweni zokugaya amaphepha, i-polyacrylamide ingasetshenziswa njenge-flocculant ukususa izinto eziqinile ezilengayo kanye nokungcola emanzini amdaka. Isiza ekwakheni izinhlayiya ezinkulu ezibizwa ngokuthi ama-floc, ezingasuswa kalula ngenqubo yokuthuthwa noma yokuhlunga. Lokhu kunegalelo ekunciphiseni ukungcola kwamanzi kanye nokuthuthukisa ukuzinza kwemvelo kwebhizinisi lokwenza amaphepha.

Sekukonke, izakhiwo eziguquguqukayo ze-polyacrylamide ziyenza ibe yinto ebalulekile embonini yokwenza amaphepha, inegalelo ekuthuthukisweni kokusebenza kahle, ikhwalithi yomkhiqizo, kanye nokusebenza kahle kwemikhiqizo yamaphepha. Ukusetshenziswa kwe-polyacrylamide ensimini yokwenza amaphepha kuhlanganisa lonke uchungechunge lwemboni yokwenza amaphepha, kusukela ekukhiqizweni kwamaphepha kuya ekuhlanzweni kwamanzi amdaka. Akugcini nje ngokuthuthukisa ikhwalithi kanye nokusebenza kahle kokukhiqiza amaphepha, kunciphisa izindleko zokukhiqiza, kodwa futhi kwenza umnikelo omuhle ekuvikelweni kwemvelo.
