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

Lapho ukhiqiza i-putty powder kanye nosimende owomile, ukukhetha i-viscosity efanele ye-hydroxypropylylylylylylyrkyl methylcellulose (HPMC) kubalulekile ekusebenzeni komkhiqizo. Njengesengezo esibalulekile samakhemikhali, i-HPMC inemisebenzi yokuqina, ukugcinwa kwamanzi, nokuzinza.

1. Iqhaza le-HPMC ku-putty powder kanye nodaka owomile

Ukuqina
Ukugcinwa kwamanzi: I-HPMC inokugcinwa kwamanzi okuhle kakhulu futhi inganciphisa ukulahlekelwa okusheshayo kwamanzi, ngaleyo ndlela yandise isikhathi sokusebenza se-putty powder kanye nodaka owomile, oluzuzisayo ukuthuthukisa amandla nezibopho zomkhiqizo wokugcina.
Ukuqina: I-HPMC ingavimbela ukuhlukaniswa kanye nokuhlukaniswa kodaka owomile no-putty powder ngesikhathi sokugcina futhi kugcinwe ukufana kwengxube.
Ukusebenza: Ngokwenza ngcono izakhiwo ze-herological, i-HPMC ingathuthukisa ukusebenziseka komkhiqizo, okwenza kube bushelelezi ngesikhathi sokufakelwa kanye nokufafaza, kanye nokunciphisa ukucwilisa kabusha ngemuva kokwakhiwa.

2. Izici ezithinta ukukhethwa kwe-HPMC Viscosity

Lapho ukhetha i-viscosity ye-HPMC, lezici ezilandelayo ezilandelayo zidinga ukubhekwa:
Uhlobo lomkhiqizo kanye nesicelo: I-putty powder kanye nosimende owomile zinokusetshenziswa okuhlukile futhi zidinga ama-viscosities ahlukile. Isibonelo, udonga oludongeni lwe-putty ludinga ukubonakala okuphezulu kokumiswa okungcono, ngenkathi ududokotela phansi lungadinga ukubonakala okuphansi kokulululeza okungcono.
Indlela yokwakha: Izindlela ezahlukahlukene zokwakha zinezidingo ezihlukile zokuvunyelwa kwe-HPMC. Ngokuvamile uhlelo lwezandla ludinga ukubonakala okuphezulu, ngenkathi ukufafaza ngomshini kudinga ukubonakala okuphakathi nokuphansi ukuze kuqinisekiswe ukwakhiwa okubushelelezi.
Izimo zezemvelo: izinga lokushisa elikhona kanye nomswakama kungathinta ukusebenza kwe-HPMC. Ngaphansi kwezimo zokushisa eziphakeme, ukukhetha i-visseti ephakeme ye-HPMC engalawula kangcono ukulahleka kwamanzi, ngenkathi isendaweni ephakeme yomswakama, i-viscosity ephansi ye-HPMC engathuthukisa ukwakhiwa.
Uhlelo Lokuqamba: Ezinye Izithako ezifakiwe kwifomula ye-putty powder kanye nodaka owomile nazo zizothinta nokukhethwa kwe-HPMC. Isibonelo, ukuba khona kwabanye abakhulu, ama-filler noma izengezo kungadinga ukuthi ukubonwa kwe-HPMC kulungiswe ukuze kufinyelelwe ibhalansi.

3. Izindlela zokukhetha ze-HPMC Viscosity
I-viscosity ye-HPMC ngokuvamile ivezwa ku-MPA · s (Milipascal Seconds). Lokhu okulandelayo kuyizindlela ezikhethekile zokukhetha i-HPMC viscosity:

PuTTY Powder:
I-Wall Pubty Powder: I-HPMC ene-150,000-200,000 MPA - ilungele ukusebenza kwezandla kanye nezidingo zokumiswa okuphezulu.
I-Floor Putty Powder: I-HPMC ene-50,000-100,000 MPA - ilungele kakhulu ukuqinisekisa ukufukula ushukela nokusakazeka.

Udaka olomile:
UMasonry wataka: I-HPMC ene-30,000-60,000 MPA - ilungele ukuthuthukisa ukugcinwa kwamanzi kanye nokwakha ukusebenza.
Udaka oluphawula: I-HPMC ene-75,000-100,000 MPA - ingakhulisa ukuvumelana futhi ilungele uhlelo lokusebenza lwezincwadi.
I-Tile Adhesive: I-HPMC ene-100,000-150,000 MPA - ilungele ukunamathela kwe-tile edinga amandla aphezulu okubopha.
Udaka olukhethekile lwenhloso: njengodaka oluzenzakalelayo lodaka nodaka ngodaka, i-viscosity ephansi HPMC (20,000-40,000 MPMC

IV. Izincomo Ezisebenzayo Zokukhethwa kwe-HPMC Viscosity

Enqubweni yokukhiqiza yangempela, izincomo ezilandelayo kufanele zilandelwe lapho ukhetha i-HPMC Viscosity:
Ukuqinisekiswa Kwezilingo: Ngaphambi kokukhiqizwa kwesisindo, izivivinyo ezincane - zenziwa ukuqinisekisa umphumela we-HPMC viscosity ekusebenzeni komkhiqizo. Kubandakanya amapharamitha asemqoka asemqoka njengokwakha, ukugcinwa kwamanzi, kanye nesivinini esiqinile.
Izincomo zabahlinzeki: Bheka ukwesekwa kwezobuchwepheshe komphakeli we-HPMC ukuthola imininingwane enemininingwane nezincomo ngomkhiqizo. Ngokuvamile zikwazi ukunikeza amasampula we-HPMC ane -yize zibonakale ezihlolweni.
Ukulungiswa nokwenza kahle: Ngokusho komphumela wangempela wokusetshenziswa, i-viscosity ye-HPMC iyaqhubeka ilungiswa ukuze isebenze kahle ukusebenza komkhiqizo. Ngesikhathi senqubo yokufaka isicelo, ukukhethwa kwe-HPMC kulungiswa ngesikhathi kucubungula izinguquko ekwakhekeni nasezinguquko ezemvelo.

V. Ukuhlola nokulawulwa kwekhwalithi ye-HPMC Viscosity

Ngemuva kokukhetha i-HPMC nge-viscosity efanelekile, ukulawulwa kwekhwalithi nakho kukhiye:
Ukuzimisela kwe-Viscosity: Njalo hlola ukubonwa kwesisombululo se-HPMC usebenzisa i-viscometer ejwayelekile (efana ne-Brookfield Visecometer) ukuze uqinisekise ukuthi ihlangabezana nezidingo zokucaciswa.
Ukuhlolwa kokugcinwa kwamanzi: Hlola ukugcinwa kwamanzi kwe-putty powder kanye nosimende owomile ukuqinisekisa ukuthi umphumela wokugcina amanzi we-HPMC uhlangabezana namazinga alindelwe.
Ukuhlolwa kokwakha: Hlola ukusebenziseka komkhiqizo ekwakhiweni kwangempela ukuze uqinisekise ukuthi umphumela wokuqina we-HPMC akaphazamisi ukusebenza.

Ukukhetha i-HPMC nge-viscosity efanele kubalulekile ukuze kukhiqizwe i-putter-performence powder kanye nodaka owomile. Ngokuya ngokusetshenziswa komkhiqizo, indlela yokwakha, izimo zemvelo nohlelo lokuqamba, i-HPMC ene-visosities ehlukene idinga ukuthi ikhethwe ukuze kuhlangatshezwane nezidingo ezithile. Ngokuqinisekiswa kokuhlola, izincomo zabahlinzeki, ukusebenza kahle kwekhwalithi kanye nokulawulwa kwekhwalithi, kungaqinisekiswa ukuthi umkhiqizo wokugcina unokusebenza okuhle, ukugcinwa kwamanzi nokuqina, ngaleyo ndlela kuthuthukiswe ukuncintisana kwemakethe komkhiqizo.
