Hydroxypropyl methylcelculose (hpmc)yindawo ebalulekileyo yeekhemikhali. Isicelo sayo kwi-Prediaced Preser idlala iindima ezibalulekileyo, ikakhulu ekuphuculeni ukusebenza kodaka, ephuculeka i-adhesion, ukulawula umswakama, kunye nokwandisa ixesha lokwakha.
I-1. Ukuphucula ukusebenza kokusebenza kodaka
Ukusebenza okusebenzayo kwe-Premiaced Priaged kubhekiswa kudaka lodaka, kubandakanya nolwelo, iplasitiki kunye ne-adhesion. I-kimbacell®hpmc, njenge-polymer computer, inezinto ezintle ezithandekayo. Emva kokuba wongezwe ngudaka, kunokonyusa i-viscosity yodaka, yenza ubofi-mbotshelelo kwaye iyunifomu engaphezulu, iya kuphucula ukwenziwa kodaka. Ngokukodwa, i-HPMC inokwenza kube lula ukufana ngexesha lokwakha, ukunciphisa iingxaki zokwakha ezibangelwa kukudakasi kakubi, kwaye uphephe izinto zokubonakala kwamanzi ezibangelwa kukungcungcutheka kwamanzi.
2. Ukuphucula ububi bodaka
Kwiiprojekthi zokwakha, ukunamathela kodaka yenye yezinto eziphambili ukuqinisekisa uzinzo lwesakhiwo. I-HPMC inokwenza ububi obuqinileyo phakathi kodaka phakathi kodaka kwaye buyekile ngokwandisa i-viscosity yodaka. Oku kunamathela okuphuculweyo kungekuphela nje udaka ukuba lube luhlobo olungcono ngamanqanaba anjengendawo yodonga kunye nezitena, kodwa kwaye unciphise uzinzo phakathi kodaka kunye nokwandisa uzinzo.
I-3. Ukulawula ukugcinwa komswakama
I-HPMC inomthamo oqingqiweyo wokufuma. Kwi-Prediaced Derings, umswakama yenye yezona zinto ziphambili ezichaphazela ukusebenza kodaka. Ukuba umswakama uyaphuma ngokukhawuleza, isantya somatshini sodaka siya kukhawulezisa, sisiphumo sokuncipha kwentsebenzo kunye nokucutha. I-HPMC inokulibazisa ngempumelelo ukuvela komswakama kwaye igcine umswakama eluphango, ngaloo ndlela ukungcola kunexesha elaneleyo lokwenza amandla omzimba okuphendule.
4. Yandisa ixesha lokwakha
Kuba ihlala ithatha ixesha elide ukwenza iinkqubo ezinjengokwenza inkukhu kunye nokwakhiwa ngexesha lolwakhiwo, ulwandiso lwexesha lokwakha lufuna ukubaleka okuphezulu kodaka. Ukongezwa kwe-HPMC kungalibazisa ngempumelelo ixesha lodaka, ukuvumela abasebenzi bokwakha ukuba babe nexesha elingakumbi lokusebenza. Ngakumbi ekwakhiweni kwendawo enkulu, ukudlulisa ixesha elivulekileyo lodaka kunokunciphisa ubunzima bokwakha obangelwa luphawu olubangelwa lukhuni, kwaye lunciphise iingxaki ze-palaves ezinokwenzeka ngexesha lenkqubo yokwakha.
I-5. Ukuphucula ukumelana kwamanzi kunye nokuxhathisa iqanda
Enye indima ebalulekileyo edlalwa yi-HPMC e-HPMC kukuphucula ukumelana kwamanzi kunye nokuchasana neqanda kodaka. Ngenxa yobume bayo obukhethekileyo, i-HPMC inokwenza ifilimu yokukhusela i-hydrophicicity eqinileyo elunxwemeni, enyusa amandla okulala okuxhathisa ukungena kwamanzi. Oku kubaluleke kakhulu kwiimveliso ezinje ngodaka lwamanzi kunye nodaka lwangaphandle lwangaphandle, olunokuthintela ngokufezekileyo ukuba umswakama ungangeni kwaye wandise ubomi benkonzo. Ukongeza, ukongezwa kwe-HPMC kunokuphucula ukunganyangeki kweqanda kodaka, ngakumbi kwiiprojekthi zokwakha kwiindawo ezibandayo, ezinokuphepha uMonakalo we-Frouw-Thaw obangelwe kwiindawo obunobushushu.
6. Phucula uhlengahlengiso lodaka
Iindawo ezahlukeneyo zokwakha kunye neemfuno zokwakha zineemfuno ezahlukeneyo zokusebenza kodaka. I-HPMC inokuhlengahlengisa iipropathi ezahlukeneyo zodaka, ezinje ngolwenzi, i-viscosity kunye namandla, iintlobo ezahlukeneyo zodaka zinokwenziwa ngokwezixhobo zokwakha iiprojekthi zokwakha zeeprojekthi zokwakha. Umzekelo, kwi-Expresi yodonga lodaka, unamathedo oPhezulu kunye nokuchaswa kwamanzi kunokufuneka; Ngexa ukuya kwiimpawu zeTyile, ingqalelo engakumbi inokuhlawulwa ngokukodwa kunye nolwelo. I-HPMC inokutshintsha intsebenzo yodaka ngokwale mibono yahlukeneyo ukuze inike esona sisombululo sifanelekileyo sezinto.
7. Phucula umphezulu wokugqibela kodaka
I-HPMC ayinakuphuculanga umsebenzi wokwakha wodaka, kodwa kukuphucula ukungcola kunye nokugqiba komhlaba. Ngexesha lenkqubo yokwakha, isiphumo sokwakhiwa kwe-kimbacell®hpmc sinokwenza umdaka ngakumbi, ngaloo ndlela kuncitshiswa kokuvela kweengxaki ezifana nobungqingqwa emva kokwakha zintle kakhulu. Ngakumbi kwezinye iiprojekthi zokuhombisa ezineemfuno eziphezulu, ukugqobhoza komphezulu kunye nokuthambisa kodaka kuchaphazela ngokuthe ngqo umlinganiso kunye nefuthe lokugqibela lokwenza impahla, iithayile, njl njl.
Njengesongezelelo esibalulekileyo kwi-PreAgeser Presed,I-HPMCidlala indima eninzi. Ekuphuculeni ukusebenza komsebenzi, ukuphucula ubumbethe, ukuhambisa umswakama, ukuphucula ukumelana kwamanzi, ukuphucula indlela yokusebenza komphezulu akunakutyeshelwa. Njengoko iimfuno zeshishini lokwakha zodaka ziyaqhubeka nokunyuka, ukusetyenziswa kwe-HPMC kuya kuqhubela phambili inkqubela phambili yetekhnoloji yezinto zokwakha kwaye ibonelele ngeendlela eziphezulu eziphezulu kunye noluthembekileyo.
