Oku kubaluleke kakhulu kwizicelo ezifana nokubekwa kwekhonkrithi kunye nokusebenza komsebenzi, apho ukusebenza kweyona nto iphambili.
3. Ukugcinwa kwamanzi
I-HPMC isebenza njengearhente yokugcina amanzi, ukuthintela ukulahleka kwamanzi okugqithisileyo kwizixhobo zesamente ngexesha lamanqanaba okuqala okuphilisa. Oku kugcinwa kwamanzi okusebenza ukunceda ukugcina iimeko ze-hydrate egqibeleleyo zamasuntswana, ukukhuthaza ukuphuculwa kwamandla kunye nokuqina.
I-4. Ukomelela kweepropathi, amandla kunye nokuqina kwezinto ezisekwe kwisamente
Impembelelo ye-HPMC kwiipropathi ezikhulayo zezinto ezisekwe kwizixhobo zesamente zibalulekile. I-HPMC inceda ukunyusa amandla e-cocressive yekhonkrithi ngokuphucula ukusebenza kunye nokugcinwa kwamanzi kwinkqubo entsha. Ukongeza, inkqubo ephuculweyo ye-hydration iphumela ekubeni kubekho i-Demern Microscred, ephucula ukuqina komhlaba kunye nokuxhathisa kwimiba yendalo esingqongileyo efana nemijikelezo ye-flaw kunye nokuhlaselwa kwemichiza.
5. Ukunciphisa i-shrinkage
Izinto ezisekwe kwisamente zihlala zincipha ngexesha lenkqubo yokunyanga, ekhokelela kwi-rocks. I-HPMC inciphisa le ngxaki ngokunciphisa iimfuno zamanzi zomxube, ngaloo ndlela kuncitshiswa ukubakho kwendawo yokufuduka. Umxholo wamanzi olawulwayo ophakanyiswa yi-HPMC unceda ukugcina uzinzo lwezinto ezilukhuni.
I-6. I-Adhesions kunye nePropathi
I-HPMC inceda ekuphuculeni iipropathi ze-bing zesamente esekwe kwizixhobo ezisekwe kwizinto kwaye iphucula imbethensi phakathi kwezinto kunye namachiza ahlukeneyo. Oku kubaluleke kakhulu kwizicelo ezinje ngeefowuni zeTile kunye neePlasters, apho iibhondi ezomeleleyo zibaluleke kakhulu kwi-Ongenvity kunye nokusebenza kwesakhiwo.
7. Ukuphucula ubumbano
Ukongeza ekuphuculeni umlinganiso, i-HPMC inokuphucula umanyano lwezinto ezenziwa ngokwalo. Oku kuyingenelo apho izixhobo ezisekwe kwimo yesamente kufuneka zilandele umphezulu othe nkqo okanye zigcine ubume bazo ngexesha lesicelo.
8. Imiceli mngeni kunye nokuthathela ingqalelo impukane kunye nokuhambelana
Ngelixa i-HPMC inezibonelelo ezininzi, ukusebenza kwayo kuxhomekeke kwidosi efanelekileyo. Ukusebenzisana okanye ukusetyenziswa gwenxa kwe-HPMC kunokubangela iziphumo ezibi ezinjengokuzilibaziseka ixesha lokuseta okanye ukuncitshiswa kwamandla. Ukongeza, ukuhambelana nezinye izongezelelo kunye nokudityaniswa kufuneka kuthathelwe ingqalelo ukuqinisekisa ukusebenza kakuhle kwisicelo esithile.
9. Impembelelo kwiNdalo esingqongileyo
Impembelelo yokusingqongileyo yokusebenzisa i-HPMC kwizixhobo zokwakha yinkxalabo ekhulayo. Ngelixa i-HPMC ngokwayo yi-biodegrades, uzinzo olupheleleyo lwemveliso kunye nokusetyenziswa kufuneka kuqwalaselwe. Abaphandi kunye neengcali zeshishini ziphonononge ezinye izinto ezinobuhlobo obusingqongileyo ezinokubonelela ngezibonelelo ezifanayo ngaphandle kokuzibamba esingqongileyo.
ukuququmbela
Ngesishwankathelo, i-Hydroxypropyl Methylcelcelgalose idlala indima ebalulekileyo ekuphuculeni ukusebenza kwezinto ezisekwe kwisamente. Ukusuka ekuphuculeni ukusebenza kunye nokugcinwa kwamanzi kwimo etsha yokwandisa amandla, ukuqina kunye nokunamathela kwindawo enobunzima, i-HPMC inceda ekuphuculeni umgangatho wezinto zokwakha. Nangona kunjalo, ukufezekisa amandla apheleleyo e-HPMC ngelixa eqinisekisa iindlela zokwakha ezizinzileyo, umthamo, ukuhambelana nefuthe lokusingqongileyo kufuneka liqwalaselwe ngononophelo. Njengoko ishishini lokwakha liyaqhubeka ukuvela, kuqhubeka uphando kunye nophuhliso kunokukhokelela ekuqhubeleni phambili kubuchwepheshe bongezelelekileyo, ukubonelela ngezisombululo eziphuculweyo kwimiceli mngeni abajamelene nayo.
