Mukugadzirwa kweceramic, viscosity ye glaze slurry ndiyo inonyanya kukosha parameter, iyo inobata zvakananga fluidity, kufanana, sedimentation uye yekupedzisira glaze effect ye glaze. Kuti uwane iyo yakakodzera glaze maitiro, zvakakosha kuti usarudze yakakodzeraCMC (Carboxymethyl cellulose) semukobvu. CMC ndeye yakasikwa polymer komboni inowanzoshandiswa muceramic glaze slurry, ine yakanaka kukora, rheological zvimiro uye kumiswa.
1. Nzwisisa zvinodiwa viscosity ye glaze slurry
Paunenge uchisarudza CMC, iwe unofanirwa kutanga wajekesa izvo viscosity zvinodiwa zve glaze slurry. Kupenya kwakasiyana uye maitiro ekugadzira ane zvakasiyana zvinodiwa kune viscosity yeiyo glaze slurry. Kazhinji kutaura, yakakwira zvakanyanya kana yakaderera viscosity ye glaze slurry ichakanganisa kupfapfaidza, kukwesha kana kunyura kwe glaze.
Low viscosity glaze slurry: yakakodzera kupfapfaidza maitiro. Yakanyanya kuderera viscosity inogona kuve nechokwadi chekuti glaze haizovharise pfuti yekupfapfaidza panguva yekupfapfaidza uye inogona kugadzira yakawedzera yunifomu yekuputira.
Medium viscosity glaze slurry: yakakodzera kudhibha maitiro. Medium viscosity inogona kuita kuti glaze ivhare zvakaenzana pasi peceramic, uye hazvisi nyore kudonha.
Yakakwira viscosity glaze slurry: yakakodzera kubhurasha maitiro. Yakakwira viscosity glaze slurry inogona kuramba iri pamusoro kwenguva yakareba, kudzivirira yakawandisa fluid, uye nekudaro kuwana gobvu glaze layer.
Naizvozvo, kusarudzwa kweCMC kunoda kuenderana nezvinodiwa zvekugadzira.
2. Hukama pakati pekukora kuita uye viscosity yeCMC
Iko kukora kwekuita kweAnxinCel®CMC kunowanzo kutsanangurwa nehuremu hwayo hwemamorekuru, dhigirii recarboxymethylation uye huwandu hwekuwedzera.
Molecular uremu: Iyo yakakwira iyo molecular huremu hweCMC, iyo inosimba kusimba kwayo. Huremu hwema molecular huremu hunogona kuwedzera viscosity yemhinduro, kuitira kuti iite slurry yakakura panguva yekushandiswa. Naizvozvo, kana yakakwira viscosity glaze slurry ichidikanwa, yakakwira molecular uremu CMC inofanira kusarudzwa.
Digree of carboxymethylation: Iyo yakakwira dhigirii yecarboxymethylation yeCMC, iyo yakasimba kunyungudika kwayo kwemvura, uye inogona kunyatsoparadzirwa mumvura kuti iite yakakwira viscosity. MaCMC akajairwa ane madhigirii akasiyana ecarboxymethylation, uye iwo akakodzera akasiyana anogona kusarudzwa zvinoenderana nezvinodiwa zve glaze slurry.
Kuwedzera huwandu: Huwandu hwekuwedzera hweCMC inzira yakananga yekudzora viscosity ye glaze slurry. Kuwedzera kushoma CMC kunozokonzera yakaderera viscosity yekupenya, nepo kuwedzera huwandu hweCMC yakawedzerwa kuchawedzera zvakanyanya viscosity. Mukugadzirwa chaiko, huwandu hweCMC hwakawedzerwa hunowanzo pakati pe0.5% ne3%, inogadziriswa zvinoenderana nezvinodiwa chaizvo.
3. Zvinhu zvinokanganisa kusarudzwa kweCMC viscosity
Pakusarudza CMC, zvimwe zvinofurira zvinhu zvinoda kutariswa:
a. Kuumbwa kwe glaze
Kuumbwa kwe glaze kuchakanganisa zvakananga viscosity yayo zvinodiwa. Semuenzaniso, glazes ine huwandu hukuru hwehupfu hwakatsetseka hunogona kuda thickener ine yakakwirira viscosity kuchengetedza kumira kwakanaka. Magirazi ane mashoma akatsetseka particles anogona kusada yakawandisa viscosity.
b. Glaze particle size
Maglazi ane hunyoro hwepamusoro anoda CMC kuti ive nani yekukora zvivakwa kuti ive nechokwadi chekuti zvidimbu zvakanaka zvinogona kumiswa mumvura. Kana iyo viscosity yeCMC isina kukwana, hupfu hwakatsetseka hunogona kudonha, zvichikonzera kusaenzana glaze.
c. Kuoma kwemvura
Kuoma kwemvura kune imwe mhedzisiro pakunyungudika uye kukora mhedzisiro yeCMC. Kuvapo kweyakawanda calcium uye magnesium ion mumvura yakaoma kunogona kuderedza kukora kweCMC uye kutokonzera kunaya kwemvura. Paunenge uchishandisa mvura yakaoma, ungangoda kusarudza mamwe marudzi eCMC kugadzirisa dambudziko iri.
d. Kushanda tembiricha uye mwando
Yakasiyana yekushanda nharaunda tembiricha uye humidity ichakanganisawo viscosity yeCMC. Semuenzaniso, munzvimbo yekupisa kwakanyanya, mvura inoputika nekukurumidza, uye yakaderera-viscosity CMC inogona kudikanwa kudzivirira zvakanyanya-kukora kwe glaze slurry. Pane zvinopesana, nzvimbo yakaderera-yekupisa inogona kuda yakakwira viscosity CMC kuti ive nechokwadi chekugadzikana uye fluidity ye slurry.
4. Kusarudzwa kunoshanda uye kugadzirira kweCMC
Mukushandiswa chaiko, kusarudzwa uye kugadzirira kweCMC kunofanirwa kuitwa zvinoenderana nematanho anotevera:
Kusarudzwa kweAnxinCel®CMC mhando: Kutanga, sarudza yakakodzera CMC siyana. Kune akasiyana viscosity mamakisi eCMC pamusika, ayo anogona kusarudzwa zvichienderana neiyo viscosity zvinodiwa uye kumiswa zvinodiwa zve glaze slurry. Semuyenzaniso, yakaderera mamorekuru uremu CMC yakakodzera glaze slurries inoda yakaderera viscosity, nepo yakakwira molecular uremu CMC yakakodzera glaze slurries inoda yakakwirira viscosity.
Kuedza kugadzirisa viscosity: Zvinoenderana neyakajeka glaze slurry zvinodiwa, huwandu hweCMC hwakawedzerwa hunogadziriswa. Iyo yakajairwa yekuedza nzira ndeyekuwedzera zvishoma nezvishoma CMC uye kuyera viscosity yayo kusvika inodiwa viscosity renji yasvikwa.
Kuongorora kugadzikana kwe glaze slurry: Iyo yakagadzirirwa glaze slurry inoda kusiiwa kuti imire kwenguva yakati kuti ione kugadzikana kwayo. Tarisa kune kunaya kwemvura, agglomeration, nezvimwewo. Kana pane dambudziko, huwandu kana rudzi rweCMC zvingada kugadziriswa.
Gadzirisa zvimwe zvinowedzera: Paunenge uchishandisaCMC, inofanirwawo kufunga nezve kushandiswa kwezvimwe zvinowedzera, zvakadai se dispersants, leveling agents, etc. Izvi zvinowedzera zvinogona kupindirana neCMC uye zvinokanganisa kuwedzera kwayo. Naizvozvo, kana kugadzirisa CMC, zvinokoshawo kuteerera reshiyo zvimwe zvinowedzera.
Iko kushandiswa kweCMC muceramic glaze slurry ibasa rehunyanzvi, iro rinoda kutariswa kwakadzama uye kugadzirisa kunoenderana nezvinodiwa viscosity, kuumbwa, particle size, shandisa nharaunda uye zvimwe zvinhu zve glaze slurry. Kusarudzwa kunonzwisisika uye kuwedzera kweAnxinCel®CMC haingogone kuvandudza kugadzikana uye kuyerera kweiyo glaze slurry, asi zvakare inovandudza yekupedzisira glaze mhedzisiro. Naizvozvo, kuenderera mberi nekugadzirisa uye kugadzirisa mashandisiro ekushandisa kweCMC mukugadzira ndiyo kiyi yekuve nechokwadi chemhando yezvigadzirwa zveceramic.
