Ungayikhetha njani i-viscosity ye-HPMC xa uvelisa udaka lomgubo owomileyo?

Xa uvelisa udaka lomgubo owomileyo, ukukhetha i-viscofity ye-hydroxypropyl methylcelculose (HPMC) kubalulekile kuba ichaphazela ngokuthe ngqo ukusebenza kunye nokwakha kwemveliso.

1. Iipropathi ezisisiseko ze-HPMC
I-HPMC yindawo ebaluleke kakhulu kwi-powty powder kunye nodaka olosiweyo, ngokugcinwa kwamanzi kakuhle, ukuqaqanjelwa kunye nokuzinza. Uhlobo lwe-HPMC luxhomekeke kubunzima bemolekyuli kunye nenqanaba lokufakwa endaweni, kunye neyunithi ye-viscosity ihlala i-MPA.S (imizuzwana)).

2. Ukubaluleka kokukhetha i-viscofity
Ukugcinwa kwamanzi: i-HPMC nge-viscofity ephezulu ihlala igcinwe i-GOFTAL, enokuthintela ngokufanelekileyo amanzi ekufumaneni ngokukhawuleza ngexesha lokumisa, ukuqinisekisa ukuba umgubo owomileyo ubenako ukusebenza kunye nokwenza isicelo ngexesha lokwakha.
Ukutyibilika: i-HPMC ene-viscosity ephezulu inokubonelela ngefuthe elingcono, yonyusa i-viscofity yomxube, ukuthintela ukungena, kunye nokuphucula ubumbisi bendawo ethe nkqo.
Ulwelo nolwakhiwo: Ulwakhiwo olufanelekileyo lunceda umxube ukuze usasazeke ngokunzulu kwaye ube nolwelo oluhle, ukuqinisekisa isicelo esilula kunye nenqanaba ngexesha lokwakha.

3. Ukuqwalaselwa okukhethekileyo malunga nokukhethwa kwe-viscofity
Indawo yokwakha: kwiqondo lobushushu obuphezulu kunye neemeko eziphantsi zokufuma, kuyacetyiswa ukukhetha i-HPMC ngohlobo oluphezulu lokuqinisekisa ukugcinwa kwamanzi kakuhle; Kwiqondo lobushushu elisezantsi kunye neemeko eziphakamileyo zokufuma, i-HPMC ene-viscosity esezantsi inokukhethwa ukuqinisekisa ukuba ulwelo kunye nolawulo lomxube.
Uhlobo lwendawo: Amahlakani ahlukeneyo aneemfuno ezahlukeneyo ze-powty powder kunye nodaka olosiweyo. Ukufakwa kwamanye amazwe enoluvo oluqinileyo lwamanzi, ezinje ngodonga lwezitena kunye neendonga zesamente, kuyacetyiswa ukukhetha i-HPMC ngohlobo oluphezulu lokuphucula ukugcinwa kwamanzi; Ukuqulunqwa kwamanzi anolwazi olubuthathaka lwamanzi, ezinjengeBhodi yeGyppum kunye neendonga zekhonkrithi, i-HPMC kunye no-Viscosity ophakathi zinokukhethwa.
Ubunzima bokwakha: Xa kufakwa khona iingqimba, i-viscofity ephezulu ye-HPMC inokukhusela imifula kunye ne-shrinkge ngexesha lomomo; Xa kufakwa iingqimba, iphakathi kunye ne-HPMMC yokuphucula i-HPMC inokuphucula ukusebenza ngokwakha kunye nefuthe elingaphezulu.
Inkqubo yokwakha: Isicelo sencwadana yemigaqo kunye nomatshini sokutshiza sineemfuno ezahlukeneyo ze-HPMC Kiscosity. Xa isetyenziswa ngesandla, uVeksikhi oPhezulu unokuphucula ukwenziwa; Xa ikhutshelwa ngomatshini, i-HPMC ene-viscofity esezantsi inokuqinisekisa ukusebenza kakuhle kwezixhobo zokutshiza.

I-4. Iingcebiso ezikhethekileyo zokhetho lwe-viscofity
I-Poll Wallty powder: i-HPMC ngohlobo lwe-20,000-60,000 Mpa.S idla ngokukhethiwe. Olu hlobo lomgubo we-putty lufuna ukugcinwa kwamanzi kakuhle kunye neepropathi ezinkulu zokuphucula ukusebenza kunye nomgangatho womhlaba.
I-pollty powty powder: i-HPMC ene-viscosity ye-100,000-200,000 ye-MPA.S ihlala ikhethiwe. I-pollt gallty powty powder ifuna ukugcinwa kwamanzi okuphezulu kunye nokunganyangeki ukujongana notshintsho kwindawo yangaphandle.
Udaka olwamileyo: i-HPMC ene-viscofis eyahlukileyo ikhethiwe ngokokusetyenziswa okuthile. Ngokubanzi, iifowuni zeTile, iNqanaba, njl njl. Ifuna i-HPMC nge-viscofity ephezulu (), ngelixa i-viscofity ye-MPA., engama-20,000-60,000 ye-MPA.S.

I-5. Ukuqinisekiswa kovavanyo lokhetho lwe-viscofity
Kwimveliso yokwenene, kuyimfuneko ukuqinisekisa impembelelo ye-HPMC ngokunxibelelana okwahlukileyo kwintsebenzo yomgubo owomileyo nodaka olosiweyo ngovavanyo. Olona tyelelo lufanelekileyo lwe-HPMC lunokufunyanwa ngokuhlengahlengisa i-viscofity kunye nomphunga we-HPMC, uvavanyele ukugcinwa kwamanzi, ukuviswa kwamanzi, ukungcungcutheka, ukungasebenzi kakuhle komxube emva kokukhanya.

Ukukhethwa kwe-HPMC Viscofity kufuneka kuthathelwe ingqalelo izinto ezifana nokugcinwa kwamanzi, ukuqina, ukungasebenzi kunye nohlobo oluqhelekileyo. Ngovavanyo lwesayensi kunye nokukhethwa kwengqondo, ukusebenza kwemveliso kunye nefuthe lokwakha ze-poty powder kunye nodaka olomileyo lunokuphuculwa. Kwimeko ezahlukeneyo zesicelo kunye neemeko zokwakha, kubaluleke kakhulu ukukhetha i-HPMC ngohlobo olufanelekileyo lokuqinisekisa uzinzo lwemveliso kunye nolwaneliseko lomsebenzisi.
