Umhlinzeki we-Polyacrylic Acid (PAA) eNingizimu Afrika
I-polymer ehlakazayo kanye ne-threshold scale inhibitor yamanzi okupholisa, i-oilfield, kanye nezinhlelo ze-reverse osmosis — i-polyacrylic acid ivimbela ukufakwa kwe-scale futhi ihlakaza i-iron oxide elengayo, i-silt, kanye nezinhlayiya zobumba kuzo zonke izinhlobo eziningi zezicelo zokwelashwa kwamanzi ezimbonini.

Kuyini i-Polyacrylic Acid?
I-Polyacrylic acid (PAA) iyi-polymer ye-anionic polyelectrolyte eyenziwe nge-acrylic acid, etholakala njengefomu le-asidi noma njengosawoti we-sodium (i-sodium polyacrylate). Ekuphathweni kwamanzi, i-PAA isetshenziswa njenge-dispersant kanye ne-threshold scale inhibitor - imisebenzi emibili ebalulekile ethuthukisa ukusebenza kwesekethe yamanzi futhi inciphise ukungcola kanye nokukhula. Isisindo sama-molecule se-PAA sinquma ukugcizelela kwayo ukusebenza: amazinga aphansi e-MW (1,000–10,000 Da) asebenza kangcono njenge-threshold scale inhibitors (anamathela kumakristalu esikali sokuqala), kuyilapho amazinga aphezulu e-MW (10,000–100,000 Da) esebenza kangcono njenge-dispersants (anamathela ezinhlayiyeni ezilengayo ukuvimbela ukuhlangana).
Ukuvinjelwa Kwesikali Nokusabalala
Njengesivimbeli sesilinganiso somkhawulo, i-PAA ivimbela ukukhula kwamakristalu e-calcium carbonate, i-calcium sulfate, i-calcium phosphate, kanye ne-zinc hydroxide ngokunamathela ebusweni be-crystal growth obusebenzayo. Njenge-dispersant, i-PAA inamathela ezinhlayiyeni ze-iron oxide (ukugqwala), ubumba, udaka, kanye nomkhiqizo wokugqwala ekumisweni, okuhlinzeka ngokuzinza kwe-steric kanye ne-electrostatic okugcina izinhlayiya zihlakazekile futhi kuzivimbele ukuthi zingahlangani zibe yizinsalela ezindaweni zokushintshana kokushisa noma ezingxenyeni zamapayipi afile. Ukusabalala kwe-PAA kubalulekile ezinhlelweni ezithatha izinto eziqinile ezilengisiwe emanzini okuzenzela noma ukugqwala kwangaphakathi - ikakhulukazi emisebenzini yamapayipi amadala enezela i-iron oxide emanzini esistimu njalo.
Izicelo Kuzo Zonke Imikhakha Yokwelapha Amanzi
I-PAA iyisici semikhiqizo eminingi yokwelapha amanzi okupholisa ehlanganisiwe kwezentengiselwano, lapho isebenza khona kanye nama-phosphonates kanye nama-corrosion inhibitors ukuze inikeze isikali esiphelele, ukuhlakazeka, kanye nokulawula ukugqwala. Ezinhlelweni zokuvimbela ukugqwala ngaphambi kokwelashwa kwe-reverse osmosis (RO), i-PAA isetshenziselwa ukuvimbela ukukhushulwa kwe-membrane yi-colloidal iron kanye nezinto eziqinile ezilengisiwe. Ezinhlelweni ze-oilfield, ivimbela ukungcola okusekelwe ensimbini ekuphatheni amanzi akhiqizwayo. I-Terracore Chemicals inikeza i-polyacrylic acid kumazinga aphansi e-MW (isikali esivimbelayo) kanye ne-higher-MW (isisabalalisi) njengezixazululo zamanzi zemisebenzi yokwelapha amanzi.
Izicelo
- Ukuvimbela isikali se-calcium carbonate kanye ne-sulfate emanzini apholile
- Ukusabalala kwe-iron oxide, ubumba, kanye nodaka ezindaweni zamanzi apholile
- Ingxenye esebenzayo yephakheji yokwelapha amanzi okupholisa ehlanganisiwe
- I-RO membrane antiscalant — ukuvimbela ukungcoliswa kwe-colloidal
- I-Oilfield ikhiqize ukuvimbela ukungcola kwensimbi emanzini
- Ukusabalala kwezinhlayiya zamanzi ezinqubo zezimboni
- Isithambisi sodaka lwamanzi ebhoyila kanye nesihlanzisi sesikali
