Ubudlelwano Phakathi Kwe-Viscosity kanye Nezinga Lokushisa Le-Hydroxypropyl Methyl Cellulose (HPMC)

(1) Ukunqunywa kwe-viscosity: Umkhiqizo omisiwe ulungiswa kusixazululo samanzi esinesisindo esingu-2°C, futhi ikalwa nge-viscometer ejikelezayo ye-NDJ-1;

(2) Ukubonakala komkhiqizo kuyimpuphu, futhi umkhiqizo osheshayo uxhunywe ngokuthi "s".

Ungayisebenzisa 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 esitsheni esinyakaziswayo esinokucindezeleka okukhulu kwe-shear (imikhiqizo ye-hydroxyethyl celluloseziyancibilika emanzini abandayo, ngakho engeza 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 ngokugcwele, 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, impushana yegypsum, ubumba lwe-ceramic, njll.), engeza inani elifanele lamanzi, guba futhi ugovuze kuze kube yilapho umkhiqizo usuncibilike ngokuphelele.

Ukuqedwa kwemikhiqizo encibilikayo emanzini abandayo: imikhiqizo encibilikayo yamanzi abandayo ingafakwa ngokuqondile emanzini abandayo ukuze ichitheke. 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, ungafaki isamba esikhulu ngokuqondile noma umkhiqizo osuwenze ibhulokhi esitsheni sokuxuba;

(3) Izinga lokushisa lamanzi kanye nenani le-ph lamanzi linobudlelwano obusobala nokuhlakazeka komkhiqizo, ngakho-ke kufanele kuqashelwe ngokukhethekile;

(4) Ungangezi ezinye izinto ezine-alkali engxubeni ngaphambi kokuba impushana yomkhiqizo ifakwe emanzini, futhi ukhuphule inani elingu-ph ngemva kokuba selicwilisiwe, elizosiza 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 kuzoba nzima ukubusebenzisa;

(7) Imikhiqizo ehlakazwe ngokushesha ngeke isetshenziselwe ukudla noma emikhiqizweni yokwenza imithi.
