I-HPMC (Hydroxypropyl methylcelcelcelsulose), njengesongezo esiqhelekileyo sokwakha esisetyenziswayo, sisetyenziswa ngokubanzi ekwakheni izinto ezinjengokufa, iingubo, kunye nokubulala. Njengomthi omkhulu kunye nomonakalo, inokuphucula kakhulu ukuphucula udaka.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC yindawo ye-polymer ye-polymer efunyenwe ngokutshintsha kweekhemikhali kweselwase yendalo. Ipropathi yayo ephambili ibandakanya ukubenzela amanzi kakuhle, ukwenziwa kwamanzi, ukwenziwa kwefilimu, ukugcinwa kwamanzi kunye nokuchasana nobushushu. Isakhiwo se-molecular se-Inincel®hpMC inamaqela anjenge-hydroxyl, i-methyl kunye namaqela e-propyl, eyenza ukuba ibe yimibhobho ye-hydrogen eneemolethi zamanzi, ke itshintsha i-viscofity kunye nolwelo lwamanzi.
2. Inkcazo yokuphumelela kodaka
Ukusebenza kodaka kubhekiswa ekuhambeni kokusebenza, isicelo kunye nokuphatha udaka ngexesha lokwakhiwa, kubandakanya iplasitiki, ulwalamano lwayo, ububi, kunye nokunamathela. Ukusebenza okuhle kunokwenza kube lula ukufana nokugungqa ngexesha lokwakha, kunye nokunciphisa isiphene sokwakha esifana ne-holles kunye nemingxunya. Ke ngoko, ukuphucula ukusebenza kodaka kubaluleke kakhulu ekuphuculeni ukusebenza ngokukuko nokuqinisekisa umgangatho weprojekthi.
I-3. Impembelelo ye-HPMC ekusebenzeni kodaka
Phucula ukugcinwa kwamanzi kodaka
I-HPMC inokuphucula kakhulu ukugcinwa kwamanzi. Inciphisa ukuvela kwamanzi ngokwenza umaleko we-hydration, ngaloo ndlela kudlulisa ixesha lokuvula kunye nokuthintela udaka ukuba luphume ngokukhawuleza okanye luphulukane namanzi. Ingakumbi phantsi kweemeko ezishushu zokusingqongileyo okanye ezomileyo, i-HPMC inokugcina ukufuma kodaka kwaye ithintele ukuba ikhubazekile ngaphambi kwexesha, yenza ukuba kube lula ukusebenza ngexesha lokusebenza. Ifaneleke ngakumbi ukwakhiwa kwemigangatho enkulu kunye nokusebenza komgangatho.
Phucula ukunamathela kodaka
I-HPMC inokuphucula ukusebenza komsebenzi ophakathi kodaka kunye nomhlaba osisiseko. Amaqela ayo asebenzayo (afana ne-methyl kunye ne-hydroxypropyl) inokunxibelelana namasuntswana okuphucula ubumbano kunye nokunamathela kodaka xa kusithinje. Oku kubambeleli bokuphuculwa ngokufanelekileyo kunokunciphisa ngokufanelekileyo umngcipheko wokudibana okanye ukungqubana kwe-play ukuwela kwaye kuphuculwe ukuthembeka kokwakhiwa.
Phucula udaka lodaka
I-HPMC iphucula udaka lodaka ngokusebenzisa ukuthambisa, kokwenza kube lula kubasebenzi abakhayo ukuze basebenze ngexesha lenkqubo yokwakha. Ubuhlazo yenye yeempawu ezibalulekileyo zokusebenza kodaka. Ulwelo oluhle lunceda ukuyisebenzisa ngokukhawuleza kwiindawo ezinkulu okanye iindawo ezinobunzima bokwakha, ukunciphisa ixesha lokwakha. I-HPMC inokwandisa iipropathi ze-RIOOOLOCTION ukuba zilondoloze ulwelo oluhle nozinzo ngexesha lokumpompa, ukukrazula kunye neminye imisebenzi, kwaye ukuphepha ukopha okanye ukwahlulwa kwamanzi.
Lungisa ukungangqinelani kunye nokugungqa kodaka
Ukungqinelana kodaka kuchaphazela ngokuthe ngqo indlela yokwakha. I-Nuncel®HPMC inokulawula ukungangqinelani kodaka ngokuhlengahlengiswa kwesixa saso sokudibanisa ukuze udaka lube mncinci kakhulu kwaye lungathandanga kakhulu ukuqinisekisa iziphumo ezifanelekileyo zokwakha. Ukongeza, i-HPMC inokwandisa ukwanda kokutyibilika kodaka nokunciphisa ukungavisisani kwembambano ngexesha lokusebenza kokwakha, ngaloo ndlela kuncitshiswa ukudinwa ngexesha lokusebenza kunye nokuphucula ukusebenza ngokukuko.
Yandisa iiyure zokuvula
Ekwakheni udaka, ixesha lokuvula libhekisa kwixesha lokuba udaka lunokuhlala luhleli luhlobo olulungileyo emva kokuba isetyenziswe kumphezulu osisiseko. I-HPMC inefuthe lokulibazisa ukuvela kwamanzi, enokuthi kwandise ngempumelelo ixesha lokuvula, ngakumbi kubushushu obuphezulu okanye indawo ephantsi yokufuma. Ixesha elongezelelweyo lokuvula alinakuphucula nje ukuchaneka kokwakha, kodwa nokuphepha iingxaki ezinje ngamalungu nakwimingxunya ngexesha lenkqubo yokwakha.
Ukucutha ukopha kunye nokulibaziseka
Ukopha kunye nokulibaziseka kunokwenziwa ngexesha lenkqubo yokwakha yodaka, okuqhelekileyo kakhulu kwisimo sesamente. I-HPMC inceda ukukhusela ukwahlulwa kwamanzi kunye nokuqiniswa kunye nokucutha ukopha ngokwandisa udaka lodaka kunye nokuphucula ukusebenzisana phakathi kweemolekyuli zangaphakathi zangaphakathi. Oku kuvumela udaka ukuba luhlale luhlobo oluhle kunye nozinzo emva kokubekwa ixesha elide kwaye uphephe iziphene zokwakha.
Phucula i-rostrast yodaka
Kwiindawo ezibandayo, ukuxhathisa iqanda lodaka kubaluleke kakhulu. Ngenxa yesakhiwo sayo esikhethekileyo, i-HPMC inokwenza uthungelwano oluzinzileyo lodaka elulambo, ukunciphisa umngcipheko wokukhululwa komswakama. Ngokongeza isixa esifanelekileyo se-HPMC kudaka, ukuxhathisa iqabaka lodaka kunokuphuculwa ngokufanelekileyo, ukuthintela imingxunya kubulali kwiindawo zobushushu, kunye nokuqinisekisa umgangatho wokwakha ubushushu.
4. Izilumkiso zokusebenzisa i-HPMC
Nangona i-HPMC inokuphucula kakhulu udaka, ezi ngongoma zilandelayo kufuneka ziqatshelwe ngexesha lokusetyenziswa:
Ukulawulwa kwemali eyongezelelweyo: Ukongezwa kakhulu kwe-HPMC kuya kukhokelela ekubeni udaka olugqithisileyo lodaka, oluchaphazela ulwalamano lwayo kunye nokusebenza; Ukongeza okuncinci kakhulu akunakusebenza ngokwaneleyo ukuphucula ukusebenza. Ke ngoko, isixa esifanelekileyo semali kufuneka ilungiswe ngokweemfuno ezithile zodaka kunye nendawo yokwakha.
Ukuhambelana nezinye izongezelelo: I-HPMC inokuba nonxibelelwano oluthile kunye nezinye ii-arhente zokwakha (ezinje ngeearhente zokungena moya, i-antiwreze, njl. Njl.), Ke ngokuhambelana nezinye kufuneka zivavanywe ukuphendula okuchaseneyo.
Iimeko zokugcina: I-HPMC kufuneka igcinwe kwindawo eyomileyo, enomoya, kude nokufuma kunye namaqondo obushushu aphezulu, ukuze aqhubeke nokusebenza kakuhle.
Njengodaka olubalulekileyo,I-HPMCIdlala indima ebalulekileyo ekuphuculeni ukusebenza kodaka. Ingaphucula ukugcinwa kwamanzi, ulwelo, ukunamathela kunye nokuchasana neqanda lodaka, lwandise ixesha lokuvula kunye nokuphucula ukusebenza kokuqala. Njengoko iimfuno zeshishini lokwakha zodaka ziyaqhubeka nokwanda, i-Nqulcel®HPMC iya kusetyenziswa kakhulu kwaye kulindeleke ukuba idlale indima enkulu ekuqulunqweni kohlobo oluphakathi. Nangona kunjalo, kwiNkqubo yokufunda, abasebenzi bokwakha kufuneka bahlengahlengise ngokufanelekileyo umthamo we-HPMC ngokweemfuno ezahlukeneyo zokwakha kunye neemeko ezinokufezekiswa.
