Izinkomba eziyinhloko zokukala ikhwalithi ye-CMC yizinga lokushintshwa (DS) nobumsulwa.Ngokuvamile, izakhiwo ze-CMC zihlukile uma i-DS ihlukile;ukuphakama kwezinga lokushintsha, kungcono ukuncibilika, kanye nokuba sobala nokuzinza kwesixazululo.Ngokwemibiko, ukucaca kwe-CMC kungcono uma izinga lokushintshwa liyi-0.7-1.2, futhi i-viscosity yesisombululo sayo esinamanzi inkulu kakhulu lapho inani le-pH liyi-6-9.
Ukuze kuqinisekiswe ikhwalithi yayo, ngaphezu kokukhethwa kwe-ejenti yokufaka i-etherifying, ezinye izici ezithinta izinga lokushintsha nobumsulwa nazo kufanele zicatshangelwe, njengobudlelwano besilinganiso phakathi kwe-alkali ne-ejenti e-etherifying, isikhathi se-etherification, okuqukethwe kwamanzi esistimu, izinga lokushisa. , inani le-pH, ukugxila kwesisombululo nosawoti.
I-sodium carboxymethyl cellulose isetshenziswa kabanzi ku-petroleum, ukudla, imithi, izindwangu, ukwenza amaphepha kanye nezinye izimboni, ngakho-ke kubaluleke kakhulu ukwahlulela ngokunembile ubumsulwa bayo, futhi kuyisilinganiso sokuqinisekisa umphumela wokusetshenziswa kwayo, ke, Singabona kanjani, ukuhogela, ukuthinta, nokukhotha ukuze wahlulele ubumsulwa bayo?
1. I-sodium carboxymethyl cellulose ehlanzekile inokugcinwa kwamanzi okuphezulu kakhulu, ukudluliswa kokukhanya okuhle, futhi izinga layo lokugcinwa kwamanzi liphezulu njenge-97%.
2. Imikhiqizo enokuhlanzeka okuphezulu ngeke ihogele iphunga le-ammonia, isitashi notshwala, kodwa uma ihlanzekile, ingakwazi ukuhogela ukunambitheka okuhlukahlukene.
3. I-sodium carboxymethyl cellulose ehlanzekile i-fluffy ngokubukeka, futhi ubuningi bobuningi buncane, ububanzi buyi: 0.3-0.4 / ml;uketshezi lokuphinga kungcono, ukuzwa kwesandla kusinda kakhulu, futhi kunomehluko obalulekile ngokubukeka kwasekuqaleni.
4. Okuqukethwe kwe-chloride ku-CMC ngokuvamile kubalwa nge-CL, ngemva kokuthi okuqukethwe kwe-CL kukalwa, okuqukethwe kwe-NaCl kungaguqulelwa ku-CL%*1.65
Kunobudlelwano obuthile phakathi kokuqukethwe kwe-CMC ne-chloride, kodwa hhayi konke, kukhona ukungcola okufana ne-sodium glycolate.Ngemva kokwazi ubumsulwa, okuqukethwe kwe-NaCl kungabalwa cishe NaCl%=(100-purity)/1.5
Cl%=(100-purity)/1.5/1.65
Ngakho-ke, umkhiqizo wokukhotha ulimi unokunambitheka okunosawoti okunamandla, okubonisa ukuthi ubumsulwa abukho phezulu.
Ngesikhathi esifanayo, i-high-purity sodium carboxymethyl cellulose iyisimo se-fiber evamile, kuyilapho imikhiqizo ehlanzekile ephansi iyi-granular.Lapho uthenga umkhiqizo, kufanele ufunde izindlela ezimbalwa ezilula zokuhlonza.Ngaphezu kwalokho, kufanele ukhethe umkhiqizi onedumela elihle, ukuze ikhwalithi yomkhiqizo iqinisekiswe kakhulu.
