I-Hydroxypropyl methylcellulose (HPMC)iyikhemikhali ye-polymer yemvelo esetshenziswa kabanzi ezintweni zokwakha, ikakhulukazi ezimbozweni, ezimbozweni, ezinamathelayo nakweminye imikhiqizo. Umsebenzi oyinhloko wokuhlanganiswa kwe-HPMC ukuthuthukisa ukusebenza kokwakhiwa kwe-mortar, ukuthuthukisa ukugcinwa kwamanzi nokwandisa isikhathi sokuvula. Njengoba isidingo sezinto zokusebenza okuphezulu embonini yokwakha siqhubeka nokukhula, ukusetshenziswa kwe-HPMC kuye kwathola ukunakwa kabanzi.
1. Izakhiwo eziyisisekelo ze-HPMC
I-HPMC iyi-ether ye-cellulose encibilikayo emanzini enokumanzi okuhle, ukunamathela kanye nezakhiwo zokujiya. Ingathuthukisa kakhulu ukugcinwa kwamanzi kwe-mortar, yandise isikhathi sokuvula, futhi ithuthukise ukumelana nokuwa kanye nokusebenza kokwakhiwa kwe-mortar. Lezi zakhiwo ezinhle kakhulu zenza i-HPMC ibe ngenye yezingxube ezivamile ku-mortar nakwezinye izinto zokwakha.
2. Inqubo yokomisa udaka
Inqubo yokomisa udoti ngokuvamile ihlanganisa izingxenye ezimbili: ukuhwamuka kwamanzi kanye nokusabela kokuhwamuka kukasimende. Ukuhwamuka kukasimende kuyindlela eyinhloko yokulungisa udoti, kodwa ukuhwamuka kwamanzi ngesikhathi sokomisa nakho kudlala indima ebalulekile. Umswakama kudoti kasimende udinga ukususwa kancane kancane ngenqubo yokuhwamuka, futhi ijubane lale nqubo lithinta ngqo ikhwalithi, ukuqina kanye nokusebenza kokwakhiwa okulandelayo komkhiqizo oqediwe ngemva kokwakhiwa.
3. Umphumela we-HPMC esivinini sokomisa udaka
Ithonya lokuhlanganiswa kwe-AnxinCel®HPMC esivinini sokomisa udoti libonakala kakhulu ezicini ezimbili: ukugcinwa kwamanzi kanye nokulawulwa kokuhwamuka kwamanzi.
(1) Ukugcinwa kwamanzi okuthuthukisiwe kanye nesivinini sokomisa sehle kancane
I-HPMC inezakhiwo eziqinile zokufaka amanzi emzimbeni kanye nokugcina amanzi. Ingakha ifilimu yokufutha emanzini ukuze inciphise ukuhwamuka kwamanzi ngokushesha. Uma ukugcinwa kwamanzi emzimbeni kungcono, komisa kancane ngoba amanzi agcinwa emzimbeni isikhathi eside. Ngakho-ke, ngemva kokufaka i-HPMC, inqubo yokuhwamuka kwamanzi emzimbeni izovinjelwa ngezinga elithile, okuholela esikhathini eside sokoma.
Nakuba ukwehlisa ijubane lokuhwamuka kwamanzi kungase kwandise isikhathi sokomisa kwe-mortar, le nqubo yokomisa kancane iyasiza, ikakhulukazi ngesikhathi senqubo yokwakha, njengoba ingavimbela ngempumelelo izinkinga ezifana nokomisa kwendawo kanye nokuqhekeka kwe-mortar futhi iqinisekise ikhwalithi yokwakha.
(2) Ukulungiswa kwenqubo yokumunca usimende
Indima ye-HPMC ku-samente mortar ayigcini nje ngokuthuthukisa ukugcinwa kwamanzi. Ingalawula futhi inqubo yokumanzisa i-samente. Ngokushintsha i-rheology ye-samente, i-HPMC ingathinta izinga lokuxhumana phakathi kwezinhlayiya ze-samente nomswakama, ngaleyo ndlela ithinte izinga lokumanzisa i-samente. Kwezinye izimo, ukungezwa kwe-AnxinCel®HPMC kungase kulibazise kancane inqubo yokumanzisa i-samente, okubangela ukuthi i-samente iphole kancane. Lo mphumela uvame ukufezwa ngokulungisa ukusatshalaliswa kosayizi wezinhlayiya ze-samente kanye nokuxhumana kwezinhlayiya ze-samente, ngaleyo ndlela kuthinte isivinini sokomisa.
(3) Ukuzivumelanisa nezimo nomswakama wendawo ezungezile
I-HPMC ingathuthukisa ukumelana nokuhwamuka kwe-mortar, okwenza i-mortar izivumelanise kalula nomswakama wendawo. Endaweni eyomile, umphumela wokugcina amanzi we-HPMC ubaluleke kakhulu. Ingalibazisa ngempumelelo ukulahleka komswakama wendawo futhi inciphise imifantu yendawo ebangelwa isivinini esikhulu sokomisa. Lokhu kubaluleke kakhulu ezindaweni ezishisayo noma ezomile. Ngakho-ke, i-HPMC ayilungisi nje kuphela izinga lokuhwamuka kwamanzi, kodwa futhi ithuthukisa ukuzivumelanisa kwe-mortar nendawo yangaphandle, yandisa ngokungaqondile isikhathi sokomisa.
4. Izici ezithinta isivinini sokomisa
Ngaphezu kokwengezwa kokuhlanganiswa kwe-HPMC, ijubane lokomisa kwe-mortar liphinde lithinteke nezinye izici eziningi, okuhlanganisa:
Isilinganiso se-mortar: Isilinganiso se-samente namanzi kanye nesilinganiso se-aggregate encane ne-coarse aggregate kuzothinta okuqukethwe komswakama kwe-mortar kanye nesivinini sokomisa.
Izimo zemvelo: Izimo zokushisa, umswakama kanye nokugeleza komoya ziyizici ezibalulekile ezithinta isivinini sokomisa udoti. Endaweni enokushisa okuphezulu kanye nomswakama ophansi, amanzi ahwamuka ngokushesha, futhi okuphambene nalokho.
Ubukhulu bodaka: Ubukhulu bodaka buthinta ngqo inqubo yalo yokomisa. Izikulufo ezijiyile ngokuvamile zithatha isikhathi eside ukuze zome ngokuphelele.
5. Izinto ezicatshangelwayo mayelana nokusetshenziswa okusebenzayo
Ezisetshenzisweni ezisebenzayo, onjiniyela bezokwakha kanye nezisebenzi zokwakha bavame ukudinga ukulinganisela isivinini sokomisa se-mortar kanye nokusebenza kahle kwesakhiwo. Njengengxube, i-HPMC ingalibazisa isivinini sokomisa, kodwa lesi sici siwusizo kakhulu ezindaweni lapho isikhathi sokwakha sidinga ukugcinwa khona. Isibonelo, ezindaweni ezinokushisa okuphezulu, zomisa umoya, i-HPMC ingavimbela ngempumelelo ukoma kwendawo nokuqhekeka, iqinisekise ukusebenza okungcono kanye nesikhathi eside sokuvula se-mortar ngesikhathi sokwakha.
Kodwa-ke, kwezinye izimo ezithile, njengemiklamo edinga ukomiswa ngokushesha kodaka, kungadingeka ukulawula inaniI-HPMCwengeze noma ukhethe ifomula engenayo i-HPMC ukuze kusheshiswe inqubo yokomisa.
Njengengxube ye-mortar, i-AnxinCel® HPMC ingathuthukisa ngempumelelo ukugcinwa kwamanzi kwe-mortar, yandise isikhathi sokuvula, futhi ithinte ngokungaqondile ijubane lokomisa kwe-mortar. Ngemva kokwengeza i-HPMC, ijubane lokomisa le-mortar livame ukwehla, okunomthelela omuhle ekugwemeni izinkinga ezifana nokuqhekeka okomile ngesikhathi sokwakha. Kodwa-ke, izinguquko kwijubane lokomisa nazo zithintwa yizici ezahlukahlukene ezifana nesilinganiso se-mortar kanye nezimo zemvelo. Ngakho-ke, ekusetshenzisweni okusebenzayo, inani le-HPMC kumele likhethwe ngokufanele ngokwezimo ezithile ukuze kufezwe umphumela omuhle kakhulu wokwakha.
