(1) Ukunqunywa kweI-HPMCi-viscosity: Umkhiqizo omisiwe ulungiselelwa isixazululo esinamanzi esinesisindo esingu-2 °C, futhi ulinganiswa nge-viscometer ejikelezayo yohlobo lwe-NDJ-1;
(2) Ukubonakala komkhiqizo kuyimpushana, futhi umkhiqizo osheshayo uxhunywe ngokuthi “s” egameni lomkhiqizo.
Ungayisebenzisa kanjani i-hydroxypropyl methylcellulose?
Yengezwa ngokuqondile ngesikhathi sokukhiqiza.Le ndlela iyindlela elula futhi emfushane kakhulu edla isikhathi.Izinyathelo eziqondile yilezi:
1. Engeza inani elithile lamanzi abilayo emkhunjini oshukumisayo ngokucindezeleka okukhulu kwe-shear (umkhiqizo we-hydroxyethyl cellulose uncibilika emanzini abandayo, ngakho-ke vele ungeze amanzi abandayo);
2. Vula ukugqugquzela ngesivinini esiphansi, futhi kancane kancane uhlunga umkhiqizo esitsheni esishukumisayo;
3. Qhubeka ugqugquzela kuze kube yilapho zonke izinhlayiya sezicwile;
4. Engeza amanzi abandayo anele futhi uqhubeke ugoqa kuze kube yilapho yonke imikhiqizo ichitheka ngokuphelele (ukucaca kwesixazululo ngokusobala kwanda);
5. Bese wengeza ezinye izithako kufomula.
Lungiselela uphuzo lukamama oluzosetshenziswa: Le ndlela iwukulungisa umkhiqizo ube wutshwala kamama obunomthamo omkhulu, bese wengeza emkhiqizweni.Inzuzo yukuthi inokuguquguquka okukhulu futhi ingafakwa ngokuqondile kumkhiqizo ophelile.Izinyathelo ziyefana (1-3) endleleni yokwengeza eqondile.Ngemuva kokuthi umkhiqizo usumanzi ngokuphelele, ake ume ukuze ukupholisa kwemvelo kuncibilike, bese ugoqa ngokugcwele ngaphambi kokuwusebenzisa.Kumele kuqashelwe ukuthi i-ejenti ye-antifungal kufanele yengezwe kugologo kamama ngokushesha ngangokunokwenzeka.
Ukusebenzisa ukuxuba okomile: Ngemva kokuxuba umkhiqizo wempushana nezinto eziyimpushana ezomile ngokuphelele (njengosimende, impushana yegypsum, ubumba lwe-ceramic, njll.), engeza inani elifanele lamanzi, bese uxova ngokugcwele futhi ugovuze kuze kube yilapho umkhiqizo usuncibilike ngokuphelele.
Ukuqedwa kwemikhiqizo encibilikayo emanzini abandayo: imikhiqizo encibilikayo yamanzi abandayo ingafakwa ngokuqondile emanzini abandayo ukuze ichithwe.Ngemva kokungeza amanzi abandayo, umkhiqizo uzocwila ngokushesha.Ngemva kokuba manzi isikhathi esithile, qala ukugoqa kuze kuqedwe ngokuphelele.
Izinyathelo zokuqapha lapho ulungiselela izixazululo
(1) Imikhiqizo ngaphandle kokwelashwa okungaphezulu (ngaphandle kwe-hydroxyethyl cellulose) akufanele incibilike ngokuqondile emanzini abandayo;
(2) Kumelwe ihlungwe kancane esitsheni sokuxuba, futhi ungawufaki ngokuqondile umkhiqizo owenziwe ibhulokhi esitsheni sokuxuba ngobuningi;
(3) Inani le-pH lokushisa kwamanzi namanzi linobudlelwano obubalulekile nokuhlakazwa komkhiqizo, futhi kufanele kuqashelwe ngokukhethekile;
(4) Ungangezi ezinye izinto ezine-alkali engxubeni ngaphambi kokuba impushana yomkhiqizo ifakwe emanzini, futhi ukhuphule inani le-pH ngemva kokucwiliswa, okuzosiza ukuncibilika;
(5) Ngokusemandleni akho, engeza i-ejenti ye-antifungal kusengaphambili;
(6) Uma usebenzisa imikhiqizo ene-viscosity ephezulu, isisindo sikamama wotshwala akufanele sibe ngaphezu kuka-2.5-3%, ngaphandle kwalokho utshwala bomama kunzima ukubusebenzisa;
(7) Imikhiqizo eselashwe ngokushesha ngeke isetshenziswe ekudleni noma emikhiqizweni yezemithi.
