Tarisa pane Cellulose ethers

Nzira yekuwana sei kugadzikana kweCMC glaze slurry?

Kuwana kugadzikana kweCarboxymethyl Cellulose (CMC) glaze slurry kwakakosha kuti ive nechokwadi chekuenderana uye kuita muzvigadzirwa zveceramic. Kugadzikana mumamiriro ezvinhu aya kunoreva kuchengetedza kumira kwakafanana pasina zvimedu zvinogadzika kana kuungana nekufamba kwenguva, izvo zvinogona kukonzera kukanganisa muchigadzirwa chekupedzisira.

Kunzwisisa CMC uye Basa Rayo muGlaze Slurry

Carboxymethyl Cellulose (CMC) i polymer inonyungudika nemvura inotorwa kubva muselulosi. Inowanzoshandiswa mu ceramic glazes se binder uye rheology modifier. CMC inovandudza glaze's viscosity, ichibatsira kuchengetedza kumiswa kwezvimedu. Iyo zvakare inosimudzira kunamira kwe glaze kune iyo ceramic pamusoro uye inoderedza kuremara senge pinholes uye kukambaira.

Zvinhu Zvikuru Zvinobata CMC Glaze Slurry Kugadzikana

CMC Hunhu uye Concentration:

Kuchena: High-kuchena CMC inofanira kushandiswa kudzivirira tsvina inogona kukanganisa slurry.

Dhigirii reKutsiva (DS): Iyo DS yeCMC, iyo inoratidza avhareji nhamba yemapoka ecarboxymethyl akasungirirwa kumusana we cellulose, inokanganisa kunyungudika kwayo uye kuita kwayo. A DS pakati 0.7 uye 1.2 anowanzo akakodzera Ceramic zvikumbiro.

Molecular Weight: Yakakwira molecular uremu CMC inopa zvirinani viscosity uye kuturika zvivakwa, asi zvinogona kunetsa kunyungudika. Kuenzanisa huremu hwema molecular uye nyore kubata kwakakosha.

Hunhu hwemvura:

pH: Iyo pH yemvura inoshandiswa kugadzira slurry inofanira kunge isina kwayakarerekera kune zvishoma alkaline (pH 7-8). Mvura ine acidic kana yakanyanya alkaline inogona kukanganisa kugadzikana nekuita kweCMC.

Ionic Zvemukati: Yakakwira mazinga emunyu akanyungudika uye maion anogona kudyidzana neCMC uye kukanganisa kukora kwayo. Kushandisa deionized kana mvura yakapfava inowanzokurudzirwa.

Kugadzirira nzira:

Dissolution: CMC inofanirwa kunyungudutswa mumvura isati yawedzera zvimwe zvikamu. Kuwedzera zvishoma nezvishoma nekukuchidzira kwakasimba kunogona kudzivirira kuumbwa kwebundu.

Kusanganisa Order: Kuwedzera CMC mhinduro kune pre-yakasanganiswa glaze zvinhu kana zvinopesana zvinogona kukanganisa homogeneity uye kugadzikana. Kazhinji, kunyungudutsa CMC kutanga uyezve nekuwedzera iyo glaze zvinhu zvinoburitsa zvirinani.

Kuchembera: Kubvumira mhinduro yeCMC kukwegura kwemaawa mashoma isati yashandiswa inogona kuvandudza mashandiro ayo nekuona kuti hydration yakakwana uye kupera.

Additives uye Kudyidzana Kwazvo:

Deflocculants: Kuwedzera mashoma e deflocculants se sodium silicate kana sodium carbonate inogona kubatsira kuparadzira zvimedu zvakaenzana. Nekudaro, kushandisa zvakanyanya kunogona kutungamira kune-deflocculation uye kudzikamisa slurry.

Preservatives: Kudzivirira kukura kwemicrobial, iyo inogona kukanganisa CMC, zvinochengetedza senge biocides zvinogona kudikanwa, kunyanya kana slurry ichichengetwa kwenguva yakareba.

Mamwe maPolymers: Dzimwe nguva, mamwe mapolima kana makobvu anoshandiswa pamwe chete neCMC kugadzirisa rheology uye kugadzikana kwe glaze slurry.

Matanho Anoshanda ekudzikamisa CMC Glaze Slurry

Kugadzirisa CMC Concentration:

Sarudza iyo yakakwana yekusangana kweCMC kune yako chaiyo glaze kuumbwa kuburikidza nekuyedza. Mafungiro akajairika anotangira kubva ku0.2% kusvika 1.0% nehuremu hweiyo yakaoma glaze musanganiswa.

Zvishoma nezvishoma gadzirisa iyo CMC yekumisikidza uye tarisa viscosity uye kumiswa zvivakwa kuti uwane yakaringana. 

Kuve nechokwadi chekuti Homogeneous Kusanganiswa:

Shandisa high-shear mixers kana bhora zvigayo kuti uone kunyatsosanganiswa kweCMC uye glaze zvikamu.

Nguva nenguva tarisa slurry kuti ifanane uye gadzirisa kusanganisa paramita sezvinodiwa. 

Kudzora pH:

Gara uchitarisa uye gadzirisa pH ye slurry. Kana iyo pH ikadonha kubva pane yaunoda, shandisa akakodzera mabhafa kuchengetedza kugadzikana.

Dzivisa kuwedzera acidic kana yakanyanya alkaline zvinhu zvakananga muslurry pasina buffering chaiyo.

Kuongorora uye Kugadzirisa Viscosity:

Shandisa viscometers kuti ugare uchitarisa viscosity ye slurry. Chengetedza chinyorwa chekuverenga viscosity kuona mafambiro uye zvinogona kugadzikana nyaya.

Kana viscosity ichichinja nekufamba kwenguva, gadzirisa nekuwedzera mashoma emvura kana CMC mhinduro sezvinodiwa.

Kuchengeta uye Kubata:

Chengetedza slurry mumidziyo yakavharwa, yakachena kudzivirira kusvibiswa uye kubuda.

Gara uchimutsa slurry yakachengetwa kuti uchengetedze kumira. Shandisa mechanical stirrers kana zvichidiwa.

Dzivisa kuchengetedza kwenguva yakareba pakupisa kwepamusoro kana muzuva rakananga, izvo zvinogona kuderedza CMC.

Troubleshooting Common Issues

Kugadzirisa:

Kana zvimedu zvikagara nekukasira, tarisa iyo CMC yekumisikidza uye ona kuti yakazara hydrated.

Funga kuwedzera chidimbu che deflocculant kuti uvandudze kumiswa kwechikamu.

Gelation:

Kana iyo slurry gels, inogona kuratidza over-flocculation kana yakawandisa CMC. Rongedza kusungirirwa uye tarisa iyo ionic yemvura.

Ita shuwa kurongeka kwakaringana kwekuwedzera uye kusanganisa maitiro.

Furo:

Foam inogona kuva nyaya panguva yekusanganiswa. Shandisa antifoaming agents zvishoma kudzora furo pasina kukanganisa glaze zvivakwa.

Microbial Kukura:

Kana iyo slurry ikawedzera kunhuwa kana kuchinja kuwirirana, inogona kunge iri nekuda kwekuita kwe microbial. Wedzera biocides uye ona kuti midziyo nemidziyo yakachena.

Kuwana kugadzikana kweCMC glaze slurry kunosanganisira musanganiswa wekusarudza zvinhu zvakanaka, kudzora maitiro ekugadzirira, uye kuchengetedza kwakaringana kuchengetedza uye kubata maitiro. Nekunzwisisa basa rechikamu chega chega uye nekutarisa akakosha ma paramita senge pH, viscosity, uye chidimbu kumiswa, unogona kugadzira yakagadzikana uye yemhando yepamusoro glaze slurry. Nguva dzose kugadzirisa matambudziko uye kugadzirisa kunobva pane yakacherechedzwa kuita kuchabatsira kuchengetedza kuenderana uye kunaka mune zvigadzirwa zveceramic.
