Iqhaza Elimangalisayo Le-Polyacrylamide Enkambini Yokwenza Amaphepha

I-Polyacrylamideigama elijwayelekile lama-homopolymers e-acrylamide noma ama-copolymers namanye ama-monomers. Ingenye yama-polymers ancibilika emanzini asetshenziswa kakhulu. I-Polyacrylamide ikhona ngendlela yama-granules amhlophe futhi ingahlukaniswa ngezinhlobo ezine: i-non-ionic, i-anionic, i-cationic, ne-amphoteric ionic.

Izicelo ze-Polyacrylamide ku-Papermaking Field

Inqubo yokwenza iphepha inezigaba eziningana, okuhlanganisa ukudonsa, ukuhlola, ukuhlanza, ukucwenga, kanye nokwakha. Phakathi nalezi zinqubo, ukungcola okuhlukahlukene okufana nemicu, izigcwalisi, nezinhlawulo kukhiqizwa. Uma lokhu kungcola kungasuswanga kahle ku-pulp, kungaholela ezinkingeni ezifana nokungagelezi kahle kwamanzi kanye namandla aphansi wephepha. I-Polyacrylamide isetshenziswa kakhulu njenge-dispersant, i-retention aid, i-drainage aid, i-flocculant, ne-ejenti yokulinganisa kwinqubo yokwenza iphepha.

Ⅰ. Ukuhlakazeka

Ukwengeza i-polyacrylamide dispersant ngesikhathi senqubo yokwenza iphepha kungavimbela ngempumelelo ukuhlanganisana kwemicu futhi kuthuthukise ukufana kwephepha. Inani eliphansi lokwengeza lingakhuthaza ukuhlakazeka okuhle kwemicu yokwenza iphepha futhi lizuze umphumela omuhle kakhulu wokwenza iphepha. Ingase futhi ithuthukise ukufana kwe-pulp kanye nokuthambile kwephepha, futhi ithuthukise izakhiwo zamandla zephepha. Ilungele imikhiqizo yephepha yasendlini ehlukahlukene njengephepha lasendlini yangasese, ama-napkins, izicubu zobuso, namanye amaphepha amancane. Kwezinye izigayo zephepha, ingathatha indawo ngokuphelele i-Polyethylene Oxide (PEO).

Ⅱ. Usizo Lokugcina

I-PAM ivame ukusetshenziswa njengosizo lokugcina embonini yokwenza iphepha ukuze kwandiswe izinga lokugcinwa kwe-fiber nokunciphisa ukukhishwa kwendle. Umgomo wayo wokusebenza uwukwenza ama-flocs amakhulu anezinhlayiya ezincane, ezingasuswa kalula ku-pulp ngokusebenzisa ukuhlunga noma ukucwiliswa.

Ⅲ. I-Drainage Aid

I-PAM ingasebenza futhi njengosizo lokudonsa amanzi enqubweni yokwenza iphepha. Kwenyusa izinga lokukhipha amanzi, okwenza ukuthi iphepha lisheshe futhi lisebenzisane kahle kakhulu emshinini wephepha. Lokhu kusiza ukwandisa isivinini sokukhiqiza nokunciphisa ukusetshenziswa kwamandla ngokunciphisa isikhathi sokumisa esidingekayo ephepheni.

Ⅳ. I-ejenti yokulinganisa

Kwezinye izimo, i-polyacrylamide isetshenziswa njenge-ejenti yokulinganisa ekwenzeni iphepha ukulawula ukungena kwamanzi nolunye uketshezi eshidini lephepha. Lokhu kusiza ekuzuzeni izici ezifiselekayo ezifana nokumelana namanzi nokubamba kukayinki, ikakhulukazi ezinhlelweni lapho iphepha lidinga ukumelana nomswakama noma izinqubo zokuphrinta.

Ⅴ. I-Flocculant

Phakathi nenqubo yokwelashwa kwamanzi angcolile ezigayweni zephepha, i-polyacrylamide ingasetshenziswa njenge-flocculant ukususa izinto eziqinile ezimisiwe kanye nokungcola emanzini angcolile. Kuyasiza ukwakha izinhlayiya ezinkulu ezibizwa ngokuthi ama-flocs, ezingase zisuswe kalula ngenqubo yokwehlisa noma yokuhlunga. Lokhu kufaka isandla ekwehliseni ukungcoliswa kwamanzi kanye nokwenza ngcono ukusimama kwemvelo kwebhizinisi lokwenza amaphepha.

Sekukonke, izakhiwo eziguquguqukayo ze-polyacrylamide zikwenza kube isengezo esibalulekile embonini yokwenza iphepha, okunomthelela ekuthuthukisweni kokusebenza kahle, ikhwalithi yomkhiqizo, kanye nokusebenza kwemikhiqizo yephepha. Ukusetshenziswa kwe-polyacrylamide emkhakheni we-papermaking kuhlanganisa lonke uchungechunge lwemboni yokwenza iphepha, kusukela ekukhiqizeni iphepha kuya ekuhlanzeni kwamanzi angcolile. Akugcini nje ukuthuthukisa ikhwalithi nokusebenza kahle kokukhiqiza kwephepha, kunciphisa izindleko zokukhiqiza, kodwa futhi kwenza umnikelo omuhle ekuvikelweni kwemvelo.
