2-Acrylamide-2-methylpropanesulfonic acid CAS 15214-89-8
I-2-Acrylamide-2-methylpropanesulfonic acid (AMPS) iyi-vinyl monomer eneqembu le-sulfonic acid. Inokuqina okuhle kokushisa, nezinga lokushisa lokubola lifinyelela ku-210°C, kanti i-sodium salt homopolymer yayo inezinga lokushisa lokubola elifinyelela ku-329°C. Kusisombululo esinamanzi, izinga le-hydrolysis lihamba kancane, futhi isisombululo sikasawoti we-sodium sinokumelana okuhle kakhulu kwe-hydrolysis ngaphansi kwezimo eziphezulu ze-pH. Ngaphansi kwezimo ezine-acidic, ukumelana kwe-hydrolysis kwe-copolymer yayo kuphakeme kakhulu kunaleyo ye-polyacrylamide. I-monomer ingenziwa ibe amakristalu noma ibe yisisombululo samanzi sosawoti we-sodium. I-2-Acrylamide-2-methylpropanesulfonic acid inezinto ezinhle zokuhlanganisa, izakhiwo ze-adsorption, umsebenzi webhayoloji, umsebenzi ongaphezulu, ukuzinza kwe-hydrolysis kanye nokuzinza kokushisa.
Ukusetshenziswa
1. Ukwelashwa kwamanzi: I-homopolymer ye-AMPS monomer noma i-copolymer ene-acrylamide, i-acrylic acid namanye ama-monomers ingasetshenziswa njenge-ejenti yokuqeda udaka enqubweni yokuhlanza indle, futhi ingasetshenziswa njengensimbi, i-zinc, i-aluminium, nethusi emanzini avaliwe. amasistimu wokujikeleza. Kanye ne-corrosion inhibitors yama-alloys; ingasetshenziswa futhi njengama-ejenti okwehlisa isikali kanye nama-antiscaling kumahitha, imibhoshongo yokupholisa, izihlanzi zomoya kanye nezihlanzi zegesi.
2. I-Oilfield chemistry: Ukusetshenziswa kwemikhiqizo emkhakheni we-oilfield chemistry kukhula ngokushesha. Ububanzi bokuzibandakanya buhlanganisa izixube zikasimende zomthombo kawoyela, ama-ejenti okwelapha amanzi okumba, uketshezi olune-asidi, uketshezi oluqhekekayo, uketshezi lokuphothula kanye nezithasiselo zoketshezi olusebenzayo, njll.
3. Imicu yokwenziwa: I-AMPS iyi-monomer ebalulekile ethuthukisa izici eziphelele zeminye imicu yokwenziwa, ikakhulukazi imicu ye-acrylic noma ye-acrylic. Umthamo wayo u-1% -4% we-fiber, engathuthukisa kakhulu ubumhlophe kanye nokudaya kwe-fiber. , i-antistatic, iphefumula kanye ne-flame retardant.
4. Ukulinganisa kwezindwangu: I-copolymer ye-2-acrylamido-2-methylpropanesulfonic acid, i-ethyl acetate, ne-acrylic acid. Kuyi-ejenti yokulinganisa efanelekile yezindwangu ezihlanganisiwe zikakotini ne-polyester. Kulula ukuyisebenzisa futhi kulula ukuyisusa ngamanzi. Izici.
