IHydroxypropyl Methyl Cellulose yeeCeramics

IHydroxypropyl methyl cellulose (HPMC) yipolima enyibilikayo emanzini eqhele ukusetyenziswa kushishino lweseramikhi. I-HPMC luhlobo olulungisiweyo lweselulosi, ephuma kwimicu yezityalo. Isetyenziswa ngokubanzi njenge-binder, i-thickener, kunye ne-arhente yokumisa kwimiqulu ye-ceramic.

Kwishishini le-ceramics, i-HPMC isetyenziswa kwizicelo ezahlukeneyo, kubandakanywa ukunamathiswa kweethayile ze-ceramic, i-ceramic glazes, kunye ne-ceramic body formulations. I-HPMC iyaziwa ngeempawu zayo zokugcina amanzi ezigqwesileyo, eziyenza ibe lukhetho olufanelekileyo kwezi zicelo.

Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kwimiqulu ye-ceramic kukukwazi kwayo ukuphucula ukusebenza kunye nokunciphisa ukuqhekeka. I-HPMC isebenza njenge-thickener kunye ne-binder, enceda ukugcina i-ceramic particles inqunyanyiswe ekuqulunqweni. Oku kunciphisa umngcipheko wokumisa okanye ukuhlukana, oku kunokukhokelela ekomisweni okungalinganiyo kunye nokuqhekeka ngexesha lokudubula. Ukongeza, i-HPMC inokuphucula iplastiki kunye nokusebenza kokwenziwa kwe-ceramic, okwenza kube lula ukuphatha kunye nokumila.

Olunye uncedo lwe-HPMC kwi-ceramics kukukwazi ukuphucula ukunamathela kunye nokumelana namanzi. I-HPMC yenza ifilimu ebusweni beengqungquthela ze-ceramic, ezinokunceda ukuphucula ukunamathela kwazo kwi-substrate. Ukongezelela, ifilimu inokubonelela ngomqobo kumanzi, okunceda ukuphucula ukunyanzeliswa kwamanzi kwimveliso ye-ceramic egqityiweyo.

I-HPMC yaziwa nangokubola kwayo kunye nokhuseleko. Yinto engeyiyo ityhefu kwaye ayinakucaphukisa esetyenziswa ngokubanzi kumashishini ahlukeneyo. Oku kwenza kube lukhetho olufanelekileyo kwiifom ze-ceramic eziza kusetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa nezo ziza kudibana nokutya okanye amanzi.

Nangona kunjalo, kubalulekile ukuba uqaphele ukuba ukusebenza kwe-HPMC kwi-ceramic formulations inokuchaphazeleka kwizinto ezahlukeneyo, kubandakanywa ubungakanani be-particle kunye nokuma kwee-particle ze-ceramic, i-pH kunye nobushushu bokubunjwa, kunye neempawu ezithile ze-HPMC. . Abaqulunqi kufuneka baqwalasele le miba ngononophelo xa bekhetha ibakala elifanelekileyo kunye noxinaniso lwe-HPMC kuqulunqo lweceramic yabo.

Isishwankathelo, i-HPMC yipolymer enyibilikayo emanzini esetyenziswa ngokubanzi kushishino lweeseramikhi. Iimpawu zayo zokugcina amanzi, amandla okuphucula ukusebenza kunye nokunciphisa ukuqhekeka, kunye nokukwazi ukuphucula ukunamathela kunye nokuchasana kwamanzi kwenza kube lukhetho olufanelekileyo kwizicelo ezininzi ze-ceramic. Nangona kunjalo, abaqulunqi kufuneka baqaphele imida yayo kwaye baqinisekise ukuba ifanelekile kwisicelo esithile ngaphambi kokuba ifakwe kwi-ceramic formulation.
