Ungayikhetha kanjani i-viscosity ye-HPMC lapho ukhiqiza udaka olomile lwe-putty?

Lapho ukhiqiza udaka olomile lwe-putty, ukukhethwa kwe-puscoxypropyllllllylyll (HPMC) kubalulekile ngoba kuthinta ngqo ukusebenza komkhiqizo kanye nomphumela wokwakha womkhiqizo.

1. Izici eziyisisekelo ze-HPMC
I-HPMC isengezo esibalulekile ku-putty powder kanye nodaka owomile, ngokugcinwa kwamanzi okuhle, ukuqina nokuqina. I-viscosity ye-HPMC incike ngesisindo sayo samangqamuzana kanye nesilinganiso sokufakwa esikhundleni, kanti iyunithi le-viscosity livame ukugcwala ama-MPA.S (Milipascal Seconds).

2. Ukubaluleka kokukhethwa kwe-viscosity
Ukugcinwa kwamanzi: I-HPMC ene-viscotity ephezulu ivame ukuba nokugcinwa kwamanzi okungcono, okungavimbela ngempumelelo amanzi ekutholeni ngokushesha ngesikhathi senqubo yokomisa, ukuqinisekisa ukuthi u-putty powder kanye nokusebenza ngesikhathi sokwakha.
Ukuqina
I-Fluity kanye nokwakhiwa: I-Viscosity efanelekile isiza le ngxube ukuthi ihlakazeke ngokulinganayo futhi ibe no-fluodity, ukuqinisekisa ukusetshenziswa okulula nokulinganisa ngesikhathi sokwakha.

3. Ukucatshangelwa okuthile kokukhethwa kwe-viscosity
Imvelo yokwakha: Emazingeni aphansi aphezulu nendawo yomswakama ophansi, kunconywa ukukhetha i-HPMC nge-viscosic ephezulu yokuqinisekisa ukugcinwa kwamanzi okuhle; Emazingeni aphansi okushisa kanye nezindawo eziphakeme zomswakama, i-hpmc ene-viscosity ephansi ingakhethwa ukuze kuqinisekiswe uketshezi nokusebenza kwengxube.
Uhlobo lwe-substrate: Ama-substrates ahlukene anezidingo ezihlukile ze-putty powder kanye nodaka owomile. Okwezincwadi ezinama-substrates anokufakwa kwamanzi okuqinile, njengezindonga zezitini kanye nezindonga zikasimende, kunconywa ukukhetha i-HPMC nge-viscosity ephezulu yokwenza ukugcinwa kwamanzi; Okwezigatshana ezinokufakwa kwamanzi okubuthakathaka, njengamabhodi we-gypsum kanye nezindonga zokhonkolo, i-HPMC enokubonakala okuphakathi ingakhethwa.
Ubukhulu bokwakha: Lapho kusetshenziswa izingqimba eziwugqinsi, ukubona okuphezulu kwe-HPMC kungavimbela ukuqhekeka kanye nokugezela ngesikhathi sokomiswa; Lapho kufakwa isendlalelo emfishane, i-HPMC ephakathi nephansi nephansi ingathuthukisa ukusebenza kahle kokwakha kanye nokutholwa komhlaba.
Inqubo yokwakha: Isicelo sezandla kanye nokufafaza ngomshini kunezidingo ezihlukile zokuvunywa kwe-HPMC. Lapho kusetshenziswa ngesandla, ukuhlakanipha okulinganiselayo kungathuthukisa ukusebenza; Lapho kufafazwa ngomshini, i-HPMC ene-viscosity ephansi ingaqinisekisa ukusebenza kahle kwemishini yokufafaza.

4. Iziphakamiso ezithile zokukhethwa kwe-viscosity
I-Interior Wall Putty Powder: I-HPMC ene-viscosity ka-20,000-60,000 MPA.S ivame ukukhethwa. Lolu hlobo lwe-putty powder ludinga ukugcinwa okuhle kwamanzi kanye nokuqina kwezakhiwo ukwenza ngcono ukusebenza kanye nekhwalithi ephezulu.
Udonga lwangaphandle lwe-PubTY PUSTY: I-HPMC ene-viscosity ye-100,000-200,000 MPA.S ivame ukukhethwa. Ingaphandle lodonga lwe-putty putty lidinga ukugcinwa kwamanzi okuphezulu kanye nokuvimbela amanzi ukubhekana nezinguquko endaweni yangaphandle.
Udaka olomile: I-HPMC ene-visosities ehlukene ikhethiwe ngokuya ngokusetshenziswa okuthile. Ngokuvamile, ama-tile anamathela, ukulinganisa udaka, njll. Dinga i-HPMC nge-viscosity ephakeme (75,000-150,000 MPA.S), ngenkathi udaka olomile olusetshenziselwa i-HPMC nge-HPMC nge-viscosity ephakathi noma ephansi (20,000-60,000 MPA.S).

I-5. Ukuqinisekiswa kokuhlola kokukhethwa kwe-viscosity
Ekukhiqizweni kwangempela, kuyadingeka ukuqinisekisa ithonya le-HPMC ene-viscosities ehlukile ekusebenzeni kwe-putty powder kanye nodaka owomile ngokusebenzisa izivivinyo. I-viscosity efaneleke kakhulu ye-HPMC ingatholwa ngokulungisa i-viscosity kanye nomthamo we-HPMC, ihlola ukugcinwa kwamanzi, i-anti-sagging, ukusebenziseka kanye namandla enhlanganisela ngemuva kokuqina.

Ukukhethwa kwe-HPMC viscosity kudinga ukubheka ngokuphelele izici ezinjengokugcinwa kwamanzi, ukuqina, ukusebenziseka kanye nohlobo lwe-substrate. Ngokuhlola kwesayensi nokukhethwa okufanele, ukusebenza komkhiqizo kanye nomphumela wokwakha we-putty powder kanye nodaka owomile kungathuthukiswa. Ngezimo ezihlukile zohlelo kanye nemibandela yokwakha, kubaluleke kakhulu ukukhetha i-HPMC nge-viscosity efanelekile yokuqinisekisa ukuqina komkhiqizo nokwaneliseka komsebenzisi.
