I-Hydroxypropylylylylylyl methyl cellulose ingathuthukisa ukumelana nokuhlakazwa kosimende

I-Hydroxypropyl methyl cellulose (HPMC)Ingabe i-polymer eguquguqukayo evame ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi ukwakhiwa, ama-Pharmaceuticals kanye nokudla. Endaweni yokwakha, ikakhulukazi ku-Cement Fatar application, i-HPMC idlala indima enkulu ekuthuthukiseni izakhiwo ezahlukahlukene, kufaka phakathi ukumelana nokuhlakazeka.

I-1.Ukuqonda i-Hydroxypropyllllylyll methyl cellulose (HPMC):

Isakhiwo samakhemikhali:
I-HPMC iyi-cellulose derivative etholakala kwiselula yemvelo ngokuguqulwa kwamakhemikhali. Isakhiwo saso siqukethe ama-glucose amayunithi aphindaphindwayo ahlanganiswe ndawonye, ​​ngamaqembu we-methylypropyl anamathele kwamanye amaqembu ama-hydroxyl kumayunithi we-glucose. Lesi sakhiwo samakhemikhali sidlulisela izakhiwo ezihlukile ku-HPMC, ukulenza lincibilike emanzini futhi likwazi ukwakha izixazululo ze-viscous.

Izakhiwo ezibonakalayo:
I-allobulity yamanzi: I-HPMC iyancibilika emanzini, yakha izixazululo ze-colloidal nge-viscosity ephezulu.
Ikhono elenziwe ngefilimu: Kungakha amafilimu asobala, aguquguqukayo lapho omisiwe, okunomthelela ekusebenzeni kwawo njenge-binder nefilimu yangaphambili.
Ukuqina okushisayo: I-HPMC ikhombisa ukuqina kwamazinga okushisa ahlukahlukene, okwenza kube lulungele izinhlelo ezahlukahlukene, kubandakanya nalabo abasembonini yezokwakha.

2.Ukuxhumana kwe-HPMC ku-Cement Data:

Ukuphuculwa kokumelana nokuhlakazeka:
Ukusebenza okuthuthukile: Ukungezelelwa kwe-HPMC ku-Cement Fature kwandisa ukusebenziseka kwayo ngokwenza ngcono ukugcinwa kwamanzi. Lokhu kuphumela kumfaniswano ofanayo futhi ongaguquki, lula uhlelo lokusebenza olulula kanye nokukhohlisa ngesikhathi sokwakha.
Ukuhlukaniswa okuncishisiwe nokopha: I-HPMC isebenza njenge-binder, ivimbela ukuhlukaniswa kwamanzi kwingxube kasimende kasimende. Lokhu kunciphisa ukuhlukaniswa nokopha, ngaleyo ndlela kuthuthukise ubumbano kanye nokuqina kodaka.
I-Adhesion ethuthukisiwe: Izakhiwo ezenziwe ngefilimu ze-HPMC zinikela ekunamathisweni okungcono phakathi kwezindawo zodaka kanye nezindawo eziphansi, eziholela ekuthuthukiseni amandla ebhondi nokuqina kwezinto ezakhiwe.
Isikhathi esilawulwa sokulawula: I-HPMC nayo ingathonya isikhathi sokusetha udaka ngosimende, ukuhlinzeka ukuguquguquka kumashejuli wokwakha kanye nokuvumela ukulawula kangcono inqubo yokufaka isicelo.

Izindlela zokusebenza:
Ukulawulwa kweHydration: Ama-molecule we-HPMC asebenzisana nama-molecule wamanzi, akha ungqimba oluvikelayo azungeze izinhlayiya. Lokhu kubuyisa inqubo ye-hydration ka usimende, ukuvimbela ukuqina ngaphambi kwesikhathi nokuvumela ukukhiqizwa okuhlala isikhathi eside.
Ukuhlakazeka kwezinhlayiya: I-Hydrophilic ye-HPMC ikwenza ukwazi ukuhlakaza ngokulinganayo kuyo yonke ingxube yodaka, ukukhuthaza ukuhanjiswa okufanayo kwezinhlayiya zensimbi. Lokhu kuhlakazwa okufanayo kuthuthukisa ukuvumelana okuphelele namandla kadaka.
Ukwakheka kwamafilimu: phezu kokoma,I-HPMCyakha ifilimu elincanyana ngaphezulu kodaka, olubopha izinhlayiya ndawonye. Le filimu isebenza njengesithiyo sokuphikisana nokungena komswakama kanye nokuhlaselwa kwamakhemikhali, ukuthuthukisa ukuqina kanye nokumelana nodaka kwezici zezemvelo.

I-Hydroxypropylylylylyllul cellulose (HPMC) isebenza njengezengezo eziningi ezisebenzayo ekunikezelweni kodaka kodaka, enikeza izinzuzo ezahlukahlukene, kufaka phakathi ukumelana okuthuthukisiwe kokuhlakazeka. Izakhiwo zayo ezihlukile, ezinjenge-solubility yamanzi, amandla akha amafilimu, nokuqina okushisayo, kwenze kube yingxenye ebaluleke kakhulu emikhubeni yanamuhla yokwakha. Ngokuthuthukisa umsebenzi, ukunamathela, kanye nokusebenza okuphelele, i-HPMC inikela ekukhiqizweni kwezinhlaka ezisezingeni eliphakeme futhi ezihlala isikhathi eside kasimende, ukubhekana nezidingo ezivela embonini yezokwakha.
