Hydroxypropylmethylcellulose (HPMC) inoshandiswa zvakanyanya sebinder, thickener uye lubricant muindasitiri yeceramic. HPMC inobatsira kudzora kuyerera kweceramic slurries uye glazes, kuve nechokwadi chekupfeka uye kunamatira kwakanaka. Iyo musanganiswa wemvura inonyungudika inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro. HPMC inowanikwa mumhando dzakasiyana-siyana dzine maviscosities akasiyana uye madhigirii ekutsiva.
Zvakanakira High Viscosity HPMC
1. Kuvandudza mvura
Imwe yemabhenefiti makuru epamusoro viscosity HPMC mumakeramiki iko kugona kuvandudza kuyerera zvivakwa. Ceramic slurries uye glazes ine HPMC inoyerera zvakanyanya uye zvakaenzanirana, zvichikonzera kuenderana kwedhizaini ukobvu uye hurema hushoma. Izvi zvinonyanya kukosha kune makuru-akawanda maindasitiri ekushandisa, uko kuenderana kwakakosha kune chigadzirwa mhando.
2. Kuwedzera kunamatira
Pamusoro pekuvandudza kuyerera zvivakwa, yakakwira-viscosity HPMC inogona kuwedzera kunamira kweceramic slurries uye glazes. HPMC inoshanda sebhainda, ichibatsira kusunga zvimedu zveceramic pamwe chete uye kudzivirira kupatsanurwa panguva yekupfura. Izvi zvinogadzira zvigadzirwa zveceramic zvakasimba, zvakasimba, uye zvisinganyanyi kuputika kana kuputika.
3. Deredza kuomesa nguva
Chimwe chikomborero chepamusoro viscosity HPMC ndechokuti inoderedza nguva yekuomesa. HPMC inoumba gel-sechimiro kana yawedzerwa kumvura, inobatsira kuchengetedza unyoro uye kudzivirira kubuda. Izvi zvinobvumira ceramic slurries uye glazes kuti iome zvishoma nezvishoma uye zvakanyanya zvakaenzana pasina kuputika kana shrinkage. Izvi zvinonyanya kukosha nemagadzirirwo akaomarara uye akapfava maumbirwo, uko kunyangwe shanduko diki munguva yekuomesa inogona kukonzera kukanganisa.
4. Kuvandudza rheology
Yakakwira viscosity HPMC inogona zvakare kuvandudza rheology yeceramic slurries uye glazes. Rheology inoreva mafambiro ekuyerera kwezvinhu zviri pasi pekumanikidzwa. HPMC inowedzera viscosity yeceramic slurries uye glazes, zvichiita kuti isanyanya kudonha kana kudonha. Izvi zvinonyanya kukosha kune dzakasimukira nzvimbo, uko kunyatso shandisa uye kuramba kune simba rinokwevera zvinhu pasi kwakakosha.
5. Kuvandudza kushanda kwekupfura
Chekupedzisira, yakakwira viscosity HPMC inogona kuvandudza kupfura zvivakwa zveceramic. HPMC inobatsira kudzora kumhanya kwekupfura uye tembiricha kuve nechokwadi cheyunifomu uye yakakwana ceramic sintering. Izvi zvinogadzira yakasimba, denser ceramic ine mashoma akaremara. HPMC inobatsirawo kuderedza kupfura shrinkage, zvichikonzera kuwedzera kunoenderana zviyero uye zvirinani zvemhando yechigadzirwa.
mukupedzisa
Yakakwira viscosity HPMC yakakosha ceramic yekuwedzera ine huwandu hwemabhenefiti anosanganisira yakavandudzwa kuyerera, yakagadziridzwa adhesion, yakaderedzwa nguva yekuomeswa, yakagadziridzwa rheology uye yakavandudzwa kupfura zvivakwa. Kunyungudika kwayo mumvura kunoita kuti ive nyore kushandisa, uye kwayakabva kunoita kuti ive sarudzo ine hushamwari. Nekushandisa yakakwira-viscosity HPMC, vagadziri veceramic vanogona kugadzira zvigadzirwa zvakasimba, zvinowirirana, uye zvinoyevedza, pakupedzisira vachiwedzera kugutsikana kwevatengi uye kubudirira kwebhizinesi.
