Yintoni i-2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer CAS 40623-75-4?

I-Acrylamide-2-methylpropanesulfonic acid copolymer (AA/AMPS) yipolymer entsha enyibilikayo emanzini eyenziwe yi-free radical copolymerization ye-acrylic acid (AA) kunye ne-2-acrylamido-2-methylpropanesulfonic acid (AMPS) monomers. Ulwakhiwo lwayo lwe-molecular luqulathe amaqela e-carboxyl (- COOH), i-amide (- CONH ₂), kunye ne-sulfonic acid (- SO3H), aneempawu ezibalaseleyo zokuthintela isikali, ukusasazwa, ubushushu kunye nokumelana netyuwa. I-2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer sisixhobo se-polymer esisebenzayo kunyango lwamanzi kwimizi-mveliso, ukukhupha ioyile negesi, iikhemikhali zemihla ngemihla kunye nezinye iindawo.

Isicelo

1. Inkqubo yamanzi okupholisa ajikeleza imboni: Njengesithinteli esiphambili sesikali kunye nesisasazi, isetyenziswa kwiinkqubo zamanzi ezijikeleza i-ion ephezulu ye-chloride kwimizi-mveliso efana namandla, iikhemikhali, intsimbi, kunye ne-metallurgy. I-2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer igxile ekuthinteleni ukufakwa kwe-calcium carbonate, i-calcium sulfate, i-barium sulfate, isikali se-silicon, kunye ne-iron oxide (isikali somhlwa), ikhusela abatshintshi bobushushu kunye nemibhobho kwimiphumo yokulinganisa.

2. Kwicandelo lokutsalwa kweoyile negesi, ulwelo lokubhola/ulwelo lokugqibezela: njengesixhobo sokunciphisa i-viscosity kunye ne-shale inhibitor, i-2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer izinzisa i-wellbore kwaye ithintele ulwelo lokubhola ukuba lungaphumeleli ngenxa yobushushu obuphezulu kunye netyuwa ephezulu (ezifana needipozithi zetyuwa kunye nee-gypsum layers).

3. Inkqubo yebhoyila kunye nomphunga: 2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer esetyenziselwa ukunyanga amanzi kwiibhoyila ezinoxinzelelo oluphakathi noluphezulu, ukucinezela ukwakheka kwesikali ngaphakathi kwibhoyila, kunye nokusasaza iimveliso zokugqwala (ezifana ne-iron oxide) emanzini, zithintele ukuba zinganamatheli kumphezulu wobushushu webhoyila kwaye zenze "ukugqwala phantsi kwesikali".

4. Imizi-mveliso yeekhemikhali neyamalaphu yemihla ngemihla, iisepha: 2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer njengee-chelating kunye ne-dispersing agents, yonyusa amandla e-chelating e-calcium kunye ne-magnesium ions emanzini, iphucula isiphumo sokucoca, kwaye ithintele ukuphinda kufakwe ukungcola.
