Kushandiswa kweHPMC mune huchi ceramics

Huchi honeki dzakashandiswa zvakanyanya munzvimbo dzakasiyana siyana sekudzivirirwa kwezvakatipoteredza, maindasitiri emotokari, etycomputer yekudzvinyirira yechiuno ita kuti vave vakachinjika veChigaltic, kupisa kwenyika uye mafirita. Nekudaro, iyo yekugadzira yeuchi ceramics inoda tekinoroji yepamusoro uye zvigadzirwa zvine midziyo yepamusoro. HydroxyPropyl methylcellose (HPMC) yakaratidza kuve inosimudzira inowedzera yeuchi kwechizi nekuda kwezvivakwa zvaro uye mutengo-zvinobudirira.

HPMC ndeye isiri-ionic cellulose ether inonyanya kugadzirwa nemusikirwo cellulose. Iyo inonyungudika-inoyevedza mvura inosanganisa nyore nemvura. Sebatsiro rekugadzirisa, HPMC dzinogona kuvandudza zvivakwa zvezvinyorwa zve ceramic slurries, senge viscosity, kugadzikana uye kufanana. Mushure mekuwedzera HPMC, iyo ceramic slurry inogona kuve yakanyanyisa kuunganidzwa pane huchibiki substrate, kubatsira kudzivirira kuremara uye marara muzvikamu zvekupedzisira. Zvakare, HPMC inogona kushandiswa seyekuchinjika panguva yekuomesa uye kupfura maitiro, iyo inogona kusimudzira simba uye kuomarara kweuchi hweuchi. Kuvapo kweHPMC kunogona zvakare kuburitsa nzvimbo yepamusoro yeuchi kweuchi kweuchi, iyo inokodzera kune inobatsira maitiro.

Kuwedzerwa kweHPMC kunowedzera porosp yechizi zvechero neanenge 10%, iyo inofungidzirwa kuumbwa kweiyo yakasarudzika yakabatanidzwa pore network. Kuwedzera kwe porosity kunobatsira kune yakashata yevashandi vekuita muzvisikwa. Mukuwedzera, HPMC inogona kusimudzira simba uye kuomarara kwechiyero chechizi nekugadzira network inochinja pakati pezvimedu kuti udzivise kuparara kwekupfura. Kuwedzerwa kweHPMC kunowedzerawo nzvimbo yemukati yeuchi kweuchi kwechiyero ne 23%, izvo zvinogona kuvandudza maitiro ayo eCatalytic.

Kuwedzerwa kweHPMC kunogona kuderedza kuderera uye deformation yeuchi kwechizi, iyo inobatsira pakugadzikana kwayo. Mukuwedzera, HPMC inogona zvakare kuwedzera iyo mosgulus yeuchi kwechiyero chechizi, nekudaro tichivandudza zvivakwa zvavo zvekushandisa. HPMC zvakare inovandudza iyo catalty chiitiko chechiuno cheuchi chechizi nekuda kwekuwedzera nzvimbo nzvimbo uye zviri nani kupararira kwezvinhu zvinoshanda.

HPMC zvakare inodzivirira uchi ceramic kubva pakuremara uye kupaza panguva yekuomesa nekuumba network yakagadzikana uye inoshanduka yepamhepo pakati pezvikamu. Ivo vakagumisa kuti HPMC ndeyekukurudzira inowedzera kune yakakwirira-mhando uye inoshanda kugadzira yeuchi ceramics.

HPMC chinhu chitsva uye chinosimbisa huchi ceramic inowedzera nekuda kwekuita kwayo kwakanaka uye mutengo-zvinobudirira. Kuwedzerwa kweHPMC kunogona kuvandudza zvivakwa zvezvinyorwa, zvinokonzeresa, simba uye cantaltic kuita kweuchi kwechiyero chechizi. Mukuwedzera, HPMC inogona zvakare kugadzirisa iyo dimensional kugadzikana, mechaniki zvivakwa uye kuumbwa maitiro ehuremu hweuchi. Iko kushandiswa kweHPMC mune huchi ceramic ine mukana mukuru muminda dzakasiyana siyana. Kuwedzera kutsvagirwa kunodiwa kuti uwedzere kusimbisa uye kushandisa nzira dzeHPMC, uye kuongorora maitiro ayo echiito mune huchi muhombodo.
