Umphumela we-hydroxypropyllylylm methyl cellulose ekulweni nosimende kasimende

I-Hydroxypropyl methyl cellulose (HPMC)yi-ether ebalulekile ye-cellulose. Kusetshenziswa kabanzi ezinhlelweni zodaka ezisuselwa kusika kasimende ngenxa yezakhiwo zayo ezihlukile zenyama nangamakhemikhali kanye nokwenza ngcono ukwenziwa ngcono ekusebenzeni kwezinto zokwakha. Ikakhulu, i-KimaCell®HPMC ikhombisile imiphumela emihle kakhulu ekuthuthukiseni ukumelana nosimende kasimende.

Ukubaluleka kokulwa nokuhlakazeka

I-Anti-Displision iyinkomba yokusebenza esemqoka yodaka kasimende, okubonisa ikakhulukazi amandla kadaka ukuze alondoloze ukufana kwezinto zangaphakathi ngaphansi kwesenzo samandla angaphandle (njengokudlidliza, umthelela noma ukuthunjwa kwamanzi). Ekwakhiweni kwangempela, ukumelana okuhle okungavimba kungavimba ama-adgregates, izinto zokwakha i-cemential kanye nezengezo kungqimba yodaka kusuka ekuhlukaniseni nasekugqugquzeleni ikhwalithi yokugcina yokwakha, ngaleyo ndlela kuqinisekiswe ukufana, ukuqina kwesakhiwo.

Izici ze-hydroxypropyllylylylylylyls

I-HPMC iyi-polymer engenamanzi enezimpawu ezibalulekile ezilandelayo:

Ukuqina

Ukugcinwa kwamanzi: Ukusebenza kwayo okuhle kakhulu kokugcina amanzi kunganciphisa ngokuphumelelayo ukulahleka okusheshayo kwamanzi odongeni futhi kunciphise ingozi yokuhlakazeka okubangelwa ukuhwamuka kwamanzi.

Impahla ekwakheka ifilimu: I-HPMC izokwakha ifilimu eguquguqukayo ngemuva kokuthi udaka lukhuni, oluthuthukisa ukunamathela kwalo okungaphezulu futhi luphinde luthuthukise impahla yalo yokulwa nokuhlanekezela.

Ukugcona: kuthuthukisa izici eziswidi phakathi kwezinhlayiya kudaka, kwenza umfaniswano wokuxuba futhi uvimbele ukusakazwa.

Indlela ye-HPMC yokuthuthukisa impahla elwa nokuhlakazeka kosimende kasimende

Kuthuthukisa ukubonakala kanye nezakhiwo ze-rheological

Ngemuva kokungeza i-Kimacell®HPMC ku-Cement Jature, amaqembu we-hydroxypropyl kanye ne-methyls esesakhiweni sawo se-molecular azokwakha izibopho ze-hydrogen ngama-molecule wamanzi, ngaleyo ndlela akhuphule ukubonwa kohlelo lodaka. Isibhamu esiphakeme kakhulu singanciphisa ukunyakaza okuhlobene kwezinhlayiya zangaphakathi lapho zibhekiswe emandleni angaphandle, zithuthukise ukuqina kodaka, futhi kunciphise ukuthambekela kokuhlukanisa.

Thuthukisa ukugcinwa kwamanzi nokubambezeleka kwezinga le-hydration

I-HPMC ingakha umgoqo wokugcina amanzi afanayo ku-data twest ukuvikela amanzi ekuthobeni ngokushesha okukhulu. Umphumela wokugcina amanzi awuzukusiza ukusabela kwe-hydration kuphela ku-gundast ukuze uqhubeke ngokugcwele, kodwa futhi wehlisa umkhathi we-dilulon wendawo obangelwa ukusatshalaliswa kwamanzi okungalingani, ngaleyo ndlela uthuthukise impahla yokulwa nokuhlanekezela.

Ukuhlukaniswa okufanayo kwezinto zokwakha i-cementionates kanye nama-aggregates

Imiphumela yokuqina nokuthambiswa kwe-HPMC yenza izinhlayiya ezinhle kudaka ukuze zihlakazeke ngokulinganayo, ngaleyo ndlela zigweme ukwahlukana okubangelwa ukungezwani kwendawo.

Ukuthuthukisa ukumelana nokuphefumula kodaka

I-HPMC ithuthukisa ukumelana nodaka ukuze ishear nokudlidliza, futhi inciphise umphumela owonakalisayo wamandla angaphandle ngesakhiwo sodaka. Noma ngabe ekuxubeni, ezokuhamba noma zokwakha, izakhi ezingaphakathi kodaka zingahlala zingaguquguquki.

Izibonelo zohlelo lokusebenza kanye nokuqinisekiswa komphumela

Ucwaningo luye lwabonisa ukuthi ukubonwa kodaka lukasimende kungakhuphuka kakhulu ngokungeza u-0.2% -0.5% (okuhlobene nobuningi besisindo) se-HPMC, kanye nempahla yaso yokulwa nokuphambukiswa kuthuthukiswa kakhulu. Ngesikhathi senqubo yokwakha, udaka oluqukethe i-kimacell®HPMC lukhombisa impahla ephakeme elwa nokusakazeka ngaphansi kwezimo eziphakeme, inciphisa ukuhlaliswa okuhlanganisiwe kanye nokulahleka kosemunyu okubangelwa ukudlidliza.

Ngenxa yokuqina kwayo okuhle, ukugcinwa kwamanzi kanye nokuthambisa kwe-lubrication, i-hydroxypropylylylylylylylylk kungathuthukisa kakhulu impahla yokulwa nosimende kasimende, ngaleyo ndlela yenza ngcono ukuqina kokwakha nokuqina kwesakhiwo. Ekucwaningweni kwesikhathi esizayo, isakhiwo samangqamuzana kanye nendlela yokungezwa yeI-HPMCingayenzelwe ukuthuthukisa umphumela wayo ekusebenzeni kwezinto zokwenziwa kosimende. Ngasikhathi sinye, inhlanganisela ye-HPMC nezinye izengezo nayo kulindeleke ukuthi ithuthukise uhlelo olusebenzayo lwezinto zokwakha ezisebenzayo ngokusebenza okungcono.
