Uruhare rwibitangaza rwa Polyacrylamide mumurima wa Papermaking

Polyacrylamideni ijambo rusange kuri homopolymers ya acrylamide cyangwa copolymers hamwe nabandi ba monomers. Nimwe mumazi akoreshwa cyane mumashanyarazi. Polyacrylamide ibaho muburyo bwa granules yera kandi irashobora gushyirwa mubwoko bune: butari ionic, anionic, cationic, na amphoteric ionic.

Porogaramu ya Polyacrylamide mumashanyarazi

Igikorwa cyo gukora impapuro kigizwe nibyiciro byinshi, birimo guswera, kwerekana, gukora isuku, gutunganya, no gukora. Muri ubu buryo, havamo umwanda utandukanye nka fibre, uwuzuza, n'amande. Niba iyi myanda idakuwe neza mumashanyarazi, irashobora gukurura ibibazo nkamazi mabi hamwe nimbaraga nke zimpapuro. Polyacrylamide ikoreshwa cyane cyane nko gutatanya, imfashanyo yo kugumana, imfashanyo zamazi, flocculant, hamwe nubunini bukoreshwa mugukora impapuro.

Ⅰ. Gutatana

Ongeraho ikwirakwiza polyacrylamide mugihe cyo gukora impapuro zirashobora gukumira neza igiteranyo cya fibre no kunoza uburinganire bwimpapuro. Umubare muto wongeyeho urashobora guteza imbere gukwirakwiza neza fibre yo gukora impapuro kandi ukagera kubikorwa byiza byo gukora impapuro. Irashobora kandi kunoza impuzu hamwe nubworoherane bwimpapuro, kandi ikongerera imbaraga imbaraga zimpapuro. Irakwiriye kubicuruzwa bitandukanye byo murugo nkimpapuro zumusarani, napkins, imyenda yo mumaso, nizindi mpapuro. Mu nsyo zimwe, irashobora gusimbuza burundu Oxide ya Polyethylene (PEO).

Ⅱ. Imfashanyo yo Kubika

PAM isanzwe ikoreshwa nkimfashanyo yo kugumana inganda zikora impapuro kugirango zongere igipimo cyo kugumana fibre no kugabanya imyanda. Ihame ryakazi ryayo nugukora floc nini hamwe nuduce duto, dushobora kuvanwa muburyo bworoshye binyuze mu kuyungurura cyangwa gutembera.

Ⅲ. Imfashanyo

PAM irashobora kandi kuba imfashanyo yo gutemba mugikorwa cyo gukora impapuro. Yongera umuvuduko wamazi, igafasha kwihuta kandi neza kuvoma impapuro kumashini yimpapuro. Ibi bifasha kongera umuvuduko wumusaruro no kugabanya gukoresha ingufu mugabanya igihe cyo kumisha gikenewe kumpapuro.

Ⅳ. Umukozi

Rimwe na rimwe, polyacrylamide ikoreshwa nk'urwego runini mu gukora impapuro kugira ngo igenzure amazi n'andi mazi yinjira mu rupapuro. Ibi bifasha mukugera kubintu byifuzwa nko kurwanya amazi no gufata wino, cyane cyane mubisabwa aho impapuro zikeneye kwihanganira ubushuhe cyangwa uburyo bwo gucapa.

Ⅴ. Flocculant

Mugihe cyo gutunganya amazi mabi mu ruganda rukora impapuro, polyacrylamide irashobora gukoreshwa nka flocculant kugirango ikureho imyanda ihumanya hamwe n’imyanda ihumanya. Ifasha gukora ibice binini byitwa flocs, bishobora noneho gukurwaho byoroshye binyuze mumyanda cyangwa kuyungurura. Ibi bigira uruhare mu kugabanya umwanda w’amazi no kuzamura ibidukikije mu bucuruzi bw’impapuro.

Muri rusange, ibintu byinshi bya polyacrylamide bituma iba inyongera yingirakamaro mu nganda zikora impapuro, bigira uruhare mu kunoza imikorere, ubwiza bwibicuruzwa, no gukora ibicuruzwa byimpapuro. Ikoreshwa rya polyacrylamide mumurima wogukora impapuro zingana ninganda zose zikora impapuro, kuva kumpapuro kugeza gutunganya amazi mabi. Ntabwo izamura gusa ubuziranenge n’umusaruro wimpapuro, igabanya ibiciro byumusaruro, ahubwo inatanga umusanzu mwiza mukurengera ibidukikije.
