Izicelo ze-HPMC kwi-cares kunye nee-adhevers

Qaphela:

I-HydroxyPOpyl Methylcelcellulose ye-polymer (i-HPMC) i-polymer esetyenziswe ngokubanzi kumashishini ahlukeneyo ngenxa yepropathi ye-frieolont ekhethekileyo, amandla okwenza ifilimu, kunye neempawu ezinamathela kwifilimu. Kwingubo kunye nemihlambi, i-HPMC isebenza ngeendima ezininzi ezinomdla, isusela ekuphuculeni i-viscofity kunye nokuzinza kuphumele ukuphucula ubunamatheko kunye neepropathi zefilimu.
Amagama aphambili: i-hydroxypropyl methylcelcelculose (i-HPMC), amachaphaza, amachaphaza, i-gemology, ezenziweyo zefilimu, ukubekwa, ukuzinza.

Intshayelelo:

I-HYDROXYPOPLL Methylcelcellulose Isakhiwo sayo esahlukileyo, esibonakaliswa yi-hydroxylpropyl kunye namaqela e-methyl eqhotyoshelwe kwi-selsulose ngasemva, enika iipropathi ezizodwa eziluncedo kwezi zicelo. I-HPMC iguquguqukayo ifana nokukwazi ukufezekisa indlela yokuziphatha kakuhle, ukulawula ifilimu, kunye nokuphucula ububi, nokwenza ukuba ingabaluleki kwimizi-mveliso kunye nemizi-mveliso yokubulala.

Ukulungiswa kwe-rathoology:

Omnye wemisebenzi ephambili ye-HPMC kwi-carhengs kunye neencwadana inendima yayo kwi-suoological. Ngokulungelelanisa uxinzelelo kunye nobunzima be-phudmc, iifomulators zinokulawula ngokuchanekileyo i-viscosity kunye nokuziphatha okusebenzayo, ezibalulekileyo kwizicelo ezinje ngobugqwirha, ukutshiza, kunye nokuqengqeleka. I-HPMC isebenza njenge-thi csuuder, idlulisela i-pseudoplastity kwiziko, ukuvumela lula isicelo kunye nokuphuculwa kokufumana iyunifora. Ngaphezu koko, indlela yokuziphatha ye-Shearling-iqinisekisa ukuba inqanaba elifanelekileyo kunye nokuqulunqwa kwefilimu kwisicelo, okukhokelela kwindawo egudileyo, engenasiphene.

Ukuqulunqwa kwefilimu kunye neepropathi zomqobo:

Kwingubo, i-HPMC inegalelo elikhulu lokuqulunqwa kweefilimu kunye neepropathi zomqobo. Njengearhente yefilimu yefilimu, i-HPMC idala ungqimba oqhubekayo, okhuselayo ngaphezulu kwamantshontsho, ukudlulisela ukuqina, ukumelana nemozulu, kunye ne-roers yomqobo kwi-coatries. Iimpawu zayo zokwenza ifilimu zenza ukuba uphuhliso lweengubo ezinomlinganiso ophezulu, kubandakanya izinyithi, iiplasitiki, kunye neenkuni, ngaloo ndlela zandisa ukusetyenziswa kwemizi-mveliso eyahlukeneyo. Ukongeza, i-HPMC-esekwe kwi-HPMC ibonakalise iipropathi ezixhasayo ngokuchasene neegesi, umphunga wamanzi, kunye nezinye izinto zokusingqongileyo, zisongela ixesha lokuphila.

Ukuphuculwa komthendeleko:

Kwimidlalo yokunamathela, i-HPMC isebenza njengesithako esiphambili sokuphucula ubumbethe kumanye amaqatha. Indalo yayo ye-hydrophilic kunye nemozulu yemolekyuli iqhubela phambili intsasazo kunye nendawo ephezulu, ukukhuthaza ukumanzi kunye nokunamathela phakathi. Ngokufaka i-HPMC kwifomu yokuncamathela, abavelisi banokufumana amandla okuphuculwa kwamandla, ukunyangwa, kunye nokunyangwa kwe-Peel, kubalulekeze izicelo ukusuka ekuqulunqeni. Ngaphaya koko, amachaphaza asekwe kwi-HPMC unika izibonelelo ezifana nokuncitshiswa kwe-shrinkage, kunye nokuguquguquka kwendalo, ukulungelelaniswa kwemfuno ekhulayo yezicelo ezizinzileyo.

Uphuhliso lwenkqubo kunye nokuzinza:

Ukusetyenziswa phaya kwe-HPMC kwadlulela kwindima yayo ekuqulunqweni kophuhliso kunye namanyathelo okuzinza ngaphakathi kwemveliso kunye nemveliso ye-adheshes. Ukuhambelana kwayo nezinye iipollymers, oomongeza, kunye nezinyibilikisi zenza ukuba iifomula zisebenzele iifom zendlela yokusebenza ngokwemisebenzi ngelixa kugcinwa iindleko. Ukongeza, i-HPMC inegalelo kwiinzame zokuzinza ngokwenza lula ukuphuculwa kwemisebenzi esekwe emanzini, ukunciphisa ukuthunyelwa kwendalo (i-VOC), kunye nokukhuthaza ezinye iindlela ze-Eco kwi-Solven esekwe. Njengoko imigaqo iqinile kwaye inkxalabo yendalo esingqongileyo, i-HPMC ivele njengesixhobo esixabisekileyo sokufezekisa zombini intsebenzo kunye neenjongo ezizinzileyo kwimisebenzi kunye nemibhedu.

I-HydroxyPOpyl Methylcelcelsulose Ukungahambi kakuhle kunye nokungathobeki kwenza isiqulatho esifanelekileyo kuqulunqwa, ukuvumela abavelisi bafezekise iimfuno zomsebenzi ongqongqo ngelixa bejongana nenkxalabo yokusingqongileyo. Njengoko ishishini le-cayinti kunye ne-adheshessings liqhubeka ukuvela, i-HPMC ilungele ukuhlala ilitye lembobisi, inkqubela phambili yokuqhuba kwimveliso, ukusebenza kakuhle kunye nokuzinza.
