I-HPMC kwi-Poayings isebenza njani?

I-HPMC (i-hydroxypropyl methylcelcelcelose) sisiseko esibalulekileyo se-polymer esetyenziswa ngokubanzi kwicandelo lokuzihlaziya. Singamanzi-kunye ne-organic selfase inyibilikisi ehambelana nendima eyahlukeneyo kwingubo ethile ngenxa yempahla yayo eyodwa emzimbeni nasezikhemikhali.

I-1. Iipropathi zokwenza ifilimu
Omnye wemisebenzi ephambili ye-HPMC ingummeli wokwenza ifilimu. Emva kokuba inyibilikiswe emanzini okanye i-organic yeSolvent, ingenza isisombululo esifanayo, kwaye emva kokuba isoyile i-Evapose, iyifilimu enomzimba. Le filimu inamandla amahle kunye nokuguquguquka ngelixa kubonelela ngokhuseleko kumhlaba wesithamo. Umzekelo, kwi-I-HPMCS, i-HPMC ibonelela ngemisebenzi efana nokunganyangeki komswakama kunye nokukhanya kwedwa, eyandisa uzinzo lwamachiza.

I-2. Umthendeleko
UVIKILE OKANYE I-HPMC yenza ukuba isebenze njenge-binder, inceda izixhobo zokuhamba ngokulandela ngcono kumhlaba omkhulu. Emva kokuphilisa, inokuphucula amandla aphezulu phakathi kokuthuka kunye nokuthintela ukuthuthuzela ukusuka ekuthinteleni okanye ukuqhekeka.

I-3. Ukuthamba kunye nokuzinzisa
I-HPMC inesakhono esihle kwaye sinokunyusa kakhulu ukugcinwa kweenkqubo zokuziqeqesha nokuba kugxininiso olusezantsi. Olu phawu lunokuhlengahlengisa i-RUOOOOOOOOOLOGY yezinto zokudlala, inika i-th th thytropy kunye nokusebenza ngexesha lolwakhiwo. Ukongeza, isiphumo sokuqaqamba kwe-HPMC thintela ukulungisa ii-pigments okanye iifilitha kwi-commance, ukuqinisekisa ukufana kokuqulunqwa.

I-4. Ukuhamba kwamanzi kunye nokunyibilika
Amaqela e-hydrophobic (i-methyl kunye ne-hydroxypropy) ye-HPMC inika iipropathi ezithile ezihlaziyiweyo zamanzi kwaye zinokubonelela ngenqanaba elithile lokunganyangeki kwamanzi kwingubo. Kwangelo xesha, i-HPMC inokulawula ngempumelelo inqanaba lokuphuma kwamanzi, ngaloo ndlela kwadlulisa ixesha elomileyo lokuthuka kunye nokuphucula bhetyebhetye ngokwakhiwa. Ukongeza, kwezinye iimeko ezikhethekileyo (ezinjengodaka lokwakha), isiphumo sokunyanyelana se-HPMC sinokunceda ukulahleka kwamanzi, ngaloo ndlela ukuphuculwa kwamandla aphezulu.

5. Ukumiswa kunye nokuzinza
Kwingubo esekwe emanzini, i-HPMC isebenza njengearhente yokumisa ngokwandisa i-viscofity yenkqubo engamanzi, enokuthi ikhusele ngokufanelekileyo amasuntswana aqinileyo (njengemifanekiso okanye iifilimu) ezivela kumxhuzulane. Iipropathi zayo ezilungileyo zezenzo zayo zenza umbala kunye nokuhlengahlengiswa kweyunifomu yokuthintela iyunifomu, ukuphucula i-aesthetics kunye nokusebenza.

6. Lungisa ixesha elomileyo
Ukufuma okulawula iipropathi ze-HPMC kwenza ukuba iphembelele ixesha lokukomala. Ngokunciphisa inqanaba lokuphuma kwamanzi, kuyanceda ukulawula ixesha lokusasazeka kwexesha lokwahlulahlula kunye nokunyangwa ngokubanzi kokudibana, ukunqanda iingxaki zokuqhekeza okubangelwa kukukhanya okukhawulezayo.

I-7. Ukuchasana kweMozulu kunye nokukhuselwa
Ifilimu ethandekayo eyenziwe yi-HPMC inayo i-UV ethile kunye nokuxhathisa imichiza, enokukhusela umhlaba kwizinto eziyingozi kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo kwindalo esingqongileyo. Umzekelo, kwizikhuselo zokukhusela iinkuni okanye zentsimbi, i-HPMC inokuphucula ukuqina kokukhathazeka kwaye kwandiswe ubomi benkonzo.

8. Ukukhusela kwendalo kunye nokhuseleko
Njengesixhobo esingabinatyhefu kunye nendawo esinobuhlobo, i-HPMC ihlangana neemfuno eziluhlaza zeshishini lemali yanamhlanje. Kwiingubo ezininzi ezisekwe emanzini, inokuthatha indawo yezinyibilikisi zemveli, ukunciphisa ukukhutshwa kweendawo ezilungisiweyo eziguqukayo (VOC), kunye nokuphucula imeko yokwakha.

I-HPMC idlala indima eyahlukeneyo neyinto ebalulekileyo kwingubo. Ukuqulunqa kwefilimu, ukuthambisa, ukunamathela, ukuziphindezela kwamanzi kwaye i-pusflering kunye nepropathi yenza isithako esifanelekileyo senziwa sisithako esifanelekileyo. Ngokwenza ubunzima bayo bemolekyuli, isidanga sokufaka endaweni yokongeza, iimfuno zokusebenza okuphathelele kwimimandla eyahlukeneyo inokufezekiswa, njengamachiza amayeza. Ke ngoko, i-HPMC ngumncedisi obalulekileyo kuphuhliso lwetekhnoloji ye-teider yanamhlanje.
