Ukusetshenziswa kwe-Hydroxyproppropyll meth (hpmc) ku-mechanic spray fortar kukhokhelwe ukunakwa okwengeziwe nokuningi ngenxa yezinzuzo zayo ezihlukile ekuthuthukiseni ukusebenza kodaka, ukuthuthukisa ukusebenza kokwakha, kanye nokwenza ngcono ikhwalithi yokwakha. I-HPMC iyingxenye ye-polymer ene-solibity yamanzi nokunamathela okuhle, futhi isetshenziswa kabanzi ekwakhiweni, ukumboza, umuthi kanye nezinye izinkambu. Ukusetshenziswa kwayo ngodaka kwesifutho semishini kungathuthukisa ngempumelelo i-fluority, ukugcinwa kwamanzi, ukuhlanganisa amanzi kanye nokufaka amandla okubopha ngodaka, ngaleyo ndlela kuthuthukise ukusebenza komuzi kanye nekhwalithi yokugcina yodaka.
1. Izici eziyisisekelo ze-Hydroxypropproserprose methylculose ether
I-HPMC iyi-polymer esolulekayo enamanzi etholwe ukuguqulwa kwamakhemikhali kwe-polymer cellulose yemvelo, enezindawo ezinhle kakhulu ze-rheological, izakhiwo ezakha amafilimu kanye nezindawo ezikhuthazayo. I-solubity yamanzi ye-HPMC ikuvumela ukuthi ihlakazeke ngokushesha ohlelweni lodaka, ukugwema izinkinga zokwakha ezibangelwa ukuhlukaniswa okungaphelele kwezinto ze-polymer ku-polymer. Ngaphezu kwalokho, i-HPMC inokugcinwa kwamanzi okuhle kanye nekhono lokubambezela ukuhwamuka kwamanzi, okubaluleke kakhulu ekuthuthukiseni ukumelana nokuvimbela ukuqhekeka kodaka.
2. Iqhaza le-HPMC ku-Mechanical Spray Botar
(1) Ukuthuthukisa ukuthuthukisa uxhaso kanye nokwenza umsebenzi wokwakha
UDonde wesifutho semishini uvame ukuba ne-fluidity enhle ukuze afafazwe kahle ekwakheni kokwakha ngemishini yokufafaza. I-HPMC inomphumela omuhle wokuqina futhi ingakha isakhiwo esizinzile se-colloidal kudaka, ngaleyo ndlela yenza ngcono uketshezi lodaka. Ngokushintsha umthamo we-HPMC, ukubonwa kodaka kungalawulwa ngokunembile ukuze kuqinisekiswe ukuthi udaka akulula ukugcwala noma ukuzinza ngesikhathi sokufafaza, ngaleyo ndlela uqinisekise ukuqina kokwakhiwa.
(2) Ukuthuthukisa ukugcinwa kwamanzi
Ukugcinwa kwamanzi kuyindawo ebalulekile e-Mechanical Spray Data, ehlobene nokunamathela, isivinini sokomisa kanye nokuvimbela ukumelana nodaka. I-HPMC inokugcinwa kwamanzi okuhle kakhulu futhi ingavimba ngempumelelo amanzi ukuthi ivele ngokushesha, ngaleyo ndlela igweme izinkinga ezinjengokuqhekeka futhi iwele kudaka ngesikhathi sokwakha. I-HPMC ingasiza udaka ukuthi alondoloze umswakama ofanele ngesikhathi senqubo yokomisa, ngaleyo ndlela athuthukise ukunamathela kodaka kanye nokuqinisekisa ukuthi kungahlanganisa ngokuphelele nenqubo yokwelapha.
(3) Ukuphikiswa okwenziwe ngcono kwezindawo zokulwa
Izinhlayiya ngodaka zingahlukanisa phakathi kokugcina isikhathi eside noma ukufafaza, okungukuthi, izinhlayiya ezisindayo zihlala ezansi, okuholele ekuhlanganisweni kodaka olungalingani. I-HPMC ingathuthukisa ukwakheka kwangaphakathi kodaka, ithuthukise ukumelana nombusi kadaka, futhi igweme ukuqina kwezinhlayiyana, ngaleyo ndlela kugcinwe ukufana nokuqina kodaka. Ngale ndlela, izakhiwo ezahlukahlukene zodaka zingagcinwa zingaguquguquki ngesikhathi senqubo yokufafaza, eqinisekisa ikhwalithi yokwakha.
(4) Amandla eBonding athuthukisiwe
Amandla e-Bond kuyinkomba ebalulekile yokuhlola ikhwalithi yodaka lwe-mechanical spray. I-HPMC ingathuthukisa ngempumelelo amandla okubopha phakathi kodaka bese ungena ngaphansi kokungafani kwayo okuhle kanye ne-adsorption. Into ye-colloidal eyenziwe yi-HPMC ku-strar ingathuthukisa ukusebenzisana phakathi kwezinhlayiya zombusi futhi ithuthukise ukuboshwa kodaka, ngaleyo ndlela yenza ngcono amandla acindezelayo nokuqhekeka kokuqhekeka ngemuva kokwakha.
I-3. Umphumela wohlelo lokusebenza lwe-HPMC ku-Mechanical Spray Data
Ngocwaningo lokuhlola kanye nokwenza umsebenzi wobunjiniyela, kutholakala ukuthi ukusetshenziswa kwe-HPMC ku-Mechanical Spray Data kungathuthukisa kakhulu izakhiwo ezahlukahlukene zodaka. Ngesikhathi senqubo yokufafaza, uketshezi, ukugcinwa kwamanzi, ukumelana kwamanzi, ukumelana nokuhlukaniswa kwamanzi namandla okuqinisa ngodaka kuthuthukiswa kakhulu. Ukwenza isibonelo, ku-motara usebenzisa i-HPMC, ingaphezulu libushelelezi ngemuva kokufafaza, ukusebenza kwezokwakha kuphakeme, futhi izisebenzi zokwakha zilula ukusebenza.
Iqhaza le-HPMC ekuthuthukiseni ikhwalithi yodaka futhi yaziwa kabanzi. Kumaphrojekthi wobunjiniyela anezidingo eziphakeme ezifana nokuphikisana nokuvinjwa kwamanzi, ukumelana nokumelana, nokufakwa kwe-HPMC, ukungezwa kwe-HPMC kungathuthukisa ukusebenza kahle kodaka futhi kuqinisekiswe ikhwalithi yokwakha nokuqina.
4. Ukuqapha kokusetshenziswa kwe-HPMC ku-Mechanical Spray Data
Yize umphumela wohlelo lokusebenza lwe-HPMC ku-Mechanical Spray Datar ubalulekile, amaphuzu alandelayo asaphawulwa ngesikhathi sokusetshenziswa kwangempela:
Ukulawulwa kwemithamo: Umthamo we-HPMC udinga ukulungiswa ngokuya ngezidingo zangempela. Ukusetshenziswa ngokweqile kuzodala ukuthi udaka lube ne-viscous futhi luthinte umphumela wokwakha; Umthamo omncane kakhulu kungenzeka ungadlali ngokuphelele ukuqina kwawo, ukugcinwa kwamanzi neminye imisebenzi.
Ukuchazwa: I-HPMC idinga ukuhlakazeka ngokugcwele ku-datar ukugwema ukungahambisani nokusebenza kwasendaweni ngenxa yokuhlakazeka okungalingani. Imvamisa inconyelwe ukuncibilikisa i-HPMC kusengaphambili noma uyixube nezinye izinto ukwenza ngcono ukusabalalisa kwayo.
Ukuqondanisa namanye ama-admixtures: Ku-Mechanical Spray Bonder, kuvame ukudingekile ukusebenzisa amanye ama-admixtures, afana namanzi, njll. Ukuhambisana kwe-HPMC nalezi zinhlamvu kudinga ukuqinisekiswa ngokuhlola ukuphendula okulimazayo.
Njengesengezo sokwakha esibalulekile, i-hydroxyproppypropylylthrulose etr inamathemba okusebenza abanzi ku-mechan spray udaka. Kungathuthukisa kakhulu uketshezi, ukugcinwa kwamanzi, ukulwa namandla okulwa namandla okubopha ngodaka, okungagcini nje ngokuthuthukisa ukusebenza kombusi, kodwa futhi kuthuthukisa ikhwalithi ephelele yephrojekthi. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, ukusetshenziswa kwe-HPMC ezintweni zokwakha kuzokhula kakhulu, ukudlala indima ebalulekile ekwenzeni ngcono ukusebenza kwezokwakha kanye nekhwalithi yamaphrojekthi wokwakha.
