(1) Ukunqunywa kwe-viscosity: umkhiqizo omisiwe ulungiselelwa kwisisombululo samanzi esinesisindo esingu-2 ° C, futhi ulinganiswa nge-viscometer ejikelezayo ye-ndj-1;
(2) Ukubonakala komkhiqizo kuyimpuphu. Umkhiqizo osheshayo uxhunywe ngo-“s” futhi umkhiqizo wezinga lezemithi uxhunywe ngo-“y”. Isibonelo, i-me-4000s iwumkhiqizo osheshayo we-me-4000.
01. Isetshenziswa kanjani i-hydroxypropyl methylcellulose
Engeza ngokuqondile ngesikhathi sokukhiqiza, le ndlela iyindlela elula futhi emfushane kakhulu edla isikhathi, izinyathelo eziqondile yilezi:
1. Faka inani elithile lamanzi abilayo emkhunjini oshukumisayo ngokucindezeleka okukhulu kwe-shear (imikhiqizo ye-hydroxyethyl cellulose iyancibilika 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 inani elanele lamanzi abandayo futhi uqhubeke ugoqa kuze kube yilapho yonke imikhiqizo ichitheka ngokuphelele (ukubonakala kwesisombululo kukhula kakhulu);
5. Bese wengeza ezinye izithako kufomula.
Lungiselela uphuzo lukamama oluzosetshenziswa: Le ndlela iwukwenza umkhiqizo ube wutshwala kamama obunomthamo omkhulu kuqala, bese uwufaka emkhiqizweni. Inzuzo yukuthi inokuguquguquka okukhulu futhi ingafakwa ngokuqondile kumkhiqizo ophelile. Izinyathelo ziyefana nezinyathelo (1-3) endleleni yokwengeza eqondile. Ngemuva kokuthi umkhiqizo usumanziswe ngokuphelele, wuyeke ume ukuze ukupholisa kwemvelo kuncibilike, bese ugoqoza ngokugcwele ngaphambi kokuwusebenzisa. Kumele kuqashelwe ukuthi i-ejenti ye-antifungal kufanele yengezwe kugologo kamama ngokushesha ngangokunokwenzeka.
Ukuxuba okomile: ngemva kokuxuba ngokuphelele umkhiqizo wempushana nezinto eziyimpushana (ezifana nosimende, i-gypsum powder, ubumba lwe-ceramic, njll.), engeza inani elifanele lamanzi, uxove futhi ugovuze kuze kube yilapho umkhiqizo usuqedwa ngokuphelele.
Ukuqedwa kwemikhiqizo encibilikayo emanzini abandayo: imikhiqizo encibilikayo yamanzi abandayo ingafakwa ngokuqondile emanzini abandayo ukuze ichitheke. Ngemuva kokungeza emanzini abandayo, umkhiqizo uzocwila ngokushesha. Ngemva kokuba manzi isikhathi esithile, qala ukugoqa kuze kuqedwe ngokuphelele.
02. Izinyathelo zokuqapha lapho ulungiselela izixazululo
(1) Imikhiqizo ngaphandle kokwelashwa okungaphezulu (ngaphandle kwe-hydroxyethyl cellulose) akufanele incibilike ngokuqondile emanzini abandayo.
(2) Kumele ihlungwe kancane esitsheni sokuxuba, ungafaki isamba esikhulu ngokuqondile noma umkhiqizo osuwenze ibhulokhi esitsheni sokuxuba.
(3) Izinga lokushisa lamanzi kanye nenani le-ph lamanzi kunobudlelwano obusobala nokuhlakazeka komkhiqizo, ngakho-ke kufanele kuqashelwe ngokukhethekile.
(4) Ungafaki izinto ezine-alkali engxubeni ngaphambi kokuba impushana yomkhiqizo ifakwe emanzini. Ukuphakamisa i-pH ngemva kokucwiliswa kuzosiza ukuncibilika.
(5) Ngangokunokwenzeka, 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 buyoba nzima ukuphatha.
(7) Imikhiqizo ehlakazwe ngokushesha ngeke isetshenziselwe ukudla noma emikhiqizweni yokwenza imithi.
