I-viscosity ephezulu 200000 HPMC

I-Hydroxypropyl Methylcellulose (HPMC)iyi-non-ionic cellulose ether esetshenziswa kabanzi ekwakheni, kwezemithi, ekudleni, kwamakhemikhali nsuku zonke nakwezinye izimboni. Ngokusho kwe-viscosity yayo, i-HPMC ingahlukaniswa nge-viscosity ephansi, i-viscosity ephakathi kanye namazinga aphezulu e-viscosity. Phakathi kwazo, i-HPMC ene-viscosity engu-200000 mPa·s ingeyezinga le-viscosity ephezulu, inezimpawu ezinhle kakhulu zokuvumelana, ukwakha ifilimu kanye nokugcina amanzi, futhi inenani eliyingqayizivele lokusetshenziswa emikhakheni eminingi.

1. Izici eziyisisekelo

I-HPMC ene-viscosity ephezulu (200000 mPa·s) yenziwe nge-polymer cellulose yemvelo futhi iguqulwa yi-etherification. Ukubukeka kwayo ngokuvamile kuyimpuphu emhlophe noma engemhlophe enoketshezi oluhle kanye nokuhlakazeka kalula. Lolu hlobo lwe-HPMC lungasakazwa ngokushesha emanzini abandayo ukuze kwakheke isixazululo esibonakalayo noma esibonakalayo esiqinile. Inani layo le-viscosity libhekisela ku-viscosity enamandla elinganiswa kusisombululo samanzi esingu-2% ku-20°C, sifinyelele ku-200000 mPa·s, okubonisa ukuhambisana okuphezulu kakhulu kanye nezakhiwo ze-rheological.

2. Ukusebenza okuyinhloko

Ukugcinwa kwamanzi okuhle kakhulu

I-HPMC ene-viscosity ephezulu inamandla okumunca amanzi kanye nokugcina amanzi, ikakhulukazi ezintweni zokwakha, ingavimbela ngempumelelo amanzi ukuthi angahwamuki ngokushesha okukhulu, futhi igweme ukuqhekeka kanye nokulahlekelwa amandla okubangelwa ukulahleka kwamanzi.

Ukuqina kanye nokuthambisa

I-HPMC enezinga le-viscosity elingu-200000 inomphumela obalulekile wokujiya, futhi noma ngabe inani lokwengeza liphansi, ingakhulisa kakhulu i-viscosity yesisombululo noma uhlelo. Ngesikhathi esifanayo, inezakhiwo ezinhle zokuthambisa kanye nokwakha, okwenza upende, i-putty kanye nodaka kube bushelelezi futhi kube lula ukusebenza ngesikhathi senqubo yokwakha.

Impahla enhle yokwenza amafilimu

Lolu hlobo lwe-HPMC lungakha ifilimu eqinile, eguquguqukayo necacile ngemva kokomiswa, okusiza ekuthuthukiseni ukumelana nokuguguleka kanye nokunamathela kwesembozo.

Ukuqina kwamakhemikhali okuqinile

I-HPMC iyi-polymer engeyona i-ionic, ezinzile kuma-acid nama-alkali futhi akulula ukusabela nezinye izingxenye zamakhemikhali, okwenza ibe nokuhambisana okuhle kumafomula ayinkimbinkimbi.

3. Inkambu yesicelo

Imboni yokwakha

I-HPMC ene-viscosity ephezulu isetshenziswa kabanzi ezintweni zokwakha ezifana nodaka olomile, ingcina yethayela, udaka lokuvala ukushisa, i-putty powder, njll. Imisebenzi yayo yokujiya nokugcina amanzi ingathuthukisa kakhulu ukusebenza kokwakhiwa, ithuthukise ukunamathela kanye nezakhiwo zokungasheleli.

Imboni yezemithi

Njenge-matrix yokukhululwa kwemithi elawulwa yimithi kanye nezinto zegobolondo le-capsule, i-HPMC ene-viscosity ephezulu ingasetshenziswa njengengxenye eyinhloko yamalungiselelo okukhululwa okuqhubekayo ukuze kwandiswe isikhathi sokukhululwa kwemithi futhi kuthuthukiswe ukutholakala kwayo.

Imboni yokudla

Isetshenziswa njenge-emulsifier, i-stabilizer, i-spending agent kanye ne-thickener ekudleni, njengasekudleni okunamafutha aphansi kanye nemikhiqizo ebhakiwe ukuthuthukisa ukuthungwa kanye nokunambitheka.

Insimu yamakhemikhali yansuku zonke

I-HPMC isetshenziswa njengesithambisi kanye nesiqinisi ku-shampoo, isihlanzi sobuso, kanye ne-lotion ukuthuthukisa ukubukeka komkhiqizo kanye nomuzwa wawo.

4. Ukusetshenziswa kanye nezinyathelo zokuphepha

Uma usebenzisa i-HPMC enobuthi obukhulu, kufanele ifakwe kancane kancane emanzini ekushiseni kwegumbi bese ihlakazwa ngenkathi ixutshwa ukuze kugwenywe ukuhlangana. Ngemva kokuba uhlelo lokuhlakazeka selwakhiwe esigabeni sokuqala, kudingeka lushiywe ukuze lumanziswe ngokugcwele ukuze ekugcineni lwakhe isixazululo se-colloidal esiqinile nesibonakalayo. I-HPMC akufanele ixutshwe nama-asidi aqinile nama-alkali ukuvimbela isakhiwo sayo sama-molecule ukuthi singabhujiswa. Ngaphezu kwalokho, indawo yokugcina kufanele igweme umswakama kanye nokushisa okuphezulu ukuvimbela umkhiqizo ukuthi ungahlangani ngenxa yomswakama futhi uthinte ukusebenza.

I-viscosity ephezulu 200000 HPMCisibe yinto ebalulekile ezimbonini eziningi ngenxa yokusebenza kwayo okuhle kakhulu kanye nokuzivumelanisa nezimo emikhakheni eminingi. Ngokuthuthuka kobuchwepheshe kanye nokwanda kwesidingo semakethe, ububanzi bokusetshenziswa kwayo buzokwandiswa kakhulu. Ukuqonda izici zayo zokusebenza kanye nezindlela ezifanele zokusebenzisa kuzosebenzisa kangcono ukusebenza kwayo futhi kuthuthukise kakhulu ikhwalithi yomkhiqizo kanye nokusebenza kahle kokukhiqiza.
