Ungayisebenzisa kanjani i-hydroxypropyl methylcellulose:
Engeza ngokuqondile ekukhiqizeni, le ndlela iyindlela elula futhi emfushane kakhulu edla isikhathi, izinyathelo eziqondile zimi kanje:
1. Engeza inani elithile lamanzi abilayo (imikhiqizo ye-hydroxyethyl cellulose iyancibilika emanzini abandayo, ngakho-ke ungakwazi ukwengeza amanzi abandayo) esitsheni esiphezulu se-shear esishukumisayo;
2. Vula ukusebenza okunyakazayo nokushesha kancane, bese uhlunga kancane umkhiqizo esitsheni esinyakazayo;
3. Qhubeka ugoqa kuze kube yilapho zonke izinhlayiya zimanziswa;
4. Engeza amanzi abandayo anele futhi uqhubeke ugoqa kuze kube yilapho wonke umkhiqizo usuqedwa ngokuphelele (ukubonakala kwesisombululo kuthuthukiswa kakhulu)
5. Bese wengeza ezinye izithako kufomula
Izinto okufanele uzikhumbule lapho ulungiselela izixazululo
(1) Imikhiqizo ngaphandle kokwelashwa okungaphezulu (ngaphandlei-hydroxyethyl cellulose) akufanele zincibilike ngokuqondile emanzini abandayo
(2) Kumele ihlungwe kancane esitsheni sokuxuba, ungafaki umkhiqizo omningi ngqo esitsheni sokuxuba.
(3) Izinga lokushisa kanye nenani le-pH lamanzi linobudlelwano obusobala nokuhlakazeka komkhiqizo, ngakho-ke kufanele kuqashelwe ngokukhethekile.
(4) Ngaphambi kokuthi impushana yomkhiqizo ibe manzi, ungangezi ezinye izinto ezine-alkali engxubeni, kuphela ngemva kokuba impushana yomkhiqizo isimanzi lapho inani le-ph lingakhuphuka, elizosiza ukuchithwa.
(5) Faka kusengaphambili i-ejenti elwa nesikhunta ngangokunokwenzeka
(6) Uma usebenzisa imikhiqizo ene-viscosity ephezulu, isisindo sikamama wotshwala akufanele sidlule u-2.5% -3%, ngaphandle kwalokho utshwala bukamama kunzima ukubusebenzisa.
(7) Imikhiqizo eselashwe ngokushesha ngeke isetshenziselwe ukudla noma imithi
