4. Ukuphucula amandla okudibanisa phakathi komzimba kunye ne-glaze layer
Kwimveliso ye-ceramic, amandla okudibanisa phakathi komzimba kunye ne-glaze layer ibalulekile kumgangatho wemveliso yokugqibela. I-HPMC inokuphucula ngokufanelekileyo ukunamathela phakathi komzimba oluhlaza kunye nomgangatho we-glaze ngokusebenzisa ukunamathela kwayo kunye neempawu zokwenza ifilimu. Ifilimu ebhityileyo eyenzayo kumphezulu womzimba ayincedi kuphela ukugubungela i-glaze ngokulinganayo, kodwa iphinda iqinise ukudibanisa komzimba phakathi komzimba kunye ne-glaze layer, ukuphucula ukuqina kunye nobuhle bemveliso egqityiweyo.
5. Ukuphucula ukusebenza kakuhle kwemveliso
I-HPMC inokuphucula ukusebenza kakuhle kwemveliso ngokubanzi ngokulungiselela iiparamitha zenkqubo kwimveliso yeceramic. Ngenxa yokuqina kwayo okugqwesileyo kunye neempawu zokudibanisa, i-HPMC inokunciphisa imfuno yokufuma kwi-slurries ye-ceramic, ngaloo ndlela inciphisa ixesha lokumisa kunye nokuphucula ukusebenza kakuhle. Ukongeza, i-HPMC inokuphucula iimpawu ze-rheological kwinkqubo yokumisa, ukunciphisa i-agglomeration ngexesha lenkqubo yokutshiza, kwaye iphucule i-fluidity yomgubo, ngaloo ndlela ikhawuleza isantya sokubumba kunye nokunciphisa iindleko zemveliso.
6. Ukuphucula iimpawu zemishini yemveliso
Iimpawu zemishini yeemveliso ze-ceramic, njengamandla e-flexural kunye nobunzima, zichaphazela ngqo ubomi babo benkonzo kunye noluhlu lwesicelo. Ukusetyenziswa kwe-HPMC kwimveliso ye-ceramic kunokuphucula kakhulu ezi zixhobo zoomatshini. I-HPMC ayinakukwazi ukunciphisa kuphela ukwenzeka koxinzelelo lwangaphakathi kunye nokuqhekeka ngokuphucula inkqubo yokomisa komzimba, kodwa iphucula amandla onke kunye nokumelana nokunxiba kweemveliso ze-ceramic ngokunyusa ukunamathela komgangatho we-glaze kunye nokuthintela ukugqabhuka kwe-glaze.
7. Ukhuseleko lokusingqongileyo kunye nozinzo
