Kwinkqubo yokuvelisa i-ceramic, i-viscosity ye-glaze slurry iyipharamitha ebaluleke kakhulu, echaphazela ngokuthe ngqo umbane, ukufana, ukuchithwa kunye nomphumo wokugqibela we-glaze. Ukuze ufumane umphumo ofanelekileyo we-glaze, kubalulekile ukukhetha okufanelekileyoI-CMC (iCarboxymethyl Cellulose) njenge-thickener. I-CMC yikhompawundi yepolymer yendalo edla ngokusetyenziswa kwi-ceramic glaze slurry, enokuqina okuhle, iipropathi zerheological kunye nokunqunyanyiswa.
1. Qonda iimfuno ze-viscosity ze-glaze slurry
Xa ukhetha i-CMC, kufuneka uqale ucacise iimfuno ze-viscosity ze-glaze slurry. Ii-glazes ezahlukeneyo kunye neenkqubo zokuvelisa zineemfuno ezahlukeneyo ze-viscosity ye-glaze slurry. Ngokuqhelekileyo, i-viscosity ephezulu okanye ephantsi kakhulu ye-glaze slurry iya kuchaphazela ukutshiza, ukuxubha okanye ukudipha i-glaze.
I-viscosity ephantsi ye-glaze slurry: ilungele inkqubo yokutshiza. I-viscosity ephantsi kakhulu inokuqinisekisa ukuba i-glaze ayiyi kugubungela isibhamu sokutshiza ngexesha lokutshiza kwaye ingenza i-coating efanayo.
I-viscosity ephakathi i-glaze slurry: ilungele inkqubo yokudipha. I-viscosity ephakathi inokwenza i-glaze igubungele ngokulinganayo umphezulu we-ceramic, kwaye akukho lula ukugoba.
I-viscosity ephezulu ye-glaze slurry: ilungele inkqubo yokuxubha. I-viscosity glaze slurry ephezulu inokuhlala phezu komhlaba ixesha elide, inqande ulwelo olugqithisileyo, kwaye ngaloo ndlela ifumane umaleko oshinyeneyo weglaze.
Ke ngoko, ukhetho lweCMC kufuneka luhambelane neemfuno zenkqubo yemveliso.
2. Ubudlelwane phakathi kokuqina kokusebenza kunye ne-viscosity ye-CMC
Ukusebenza okutyebileyo kwe-AnxinCel®CMC kudla ngokumiselwa bubunzima bayo bemolekyuli, iqondo le-carboxymethylation kunye nesixa sokongeza.
Ubunzima bemolekyuli: Okukhona buphezulu ubunzima bemolekyuli ye-CMC, kokukhona bomelele isiphumo sayo sokuqina. Ubunzima bemolekyuli obuphezulu bunokunyusa i-viscosity yesisombululo, ukwenzela ukuba yenze i-slurry eninzi ngexesha lokusetyenziswa. Ngoko ke, ukuba i-viscosity glaze slurry ephezulu iyafuneka, kufuneka kukhethwe i-molecular weight CMC ephezulu.
Iqondo le-carboxymethylation: Iqondo eliphezulu le-carboxymethylation ye-CMC, inamandla ngakumbi ekunyibilikeni kwayo emanzini, kwaye inokusasazwa ngokufanelekileyo emanzini ukwenza i-viscosity ephezulu. Ii-CMCs eziqhelekileyo zinamaqondo ahlukeneyo e-carboxymethylation, kwaye iindidi ezifanelekileyo zinokukhethwa ngokweemfuno ze-glaze slurry.
Isixa esongezelelweyo: Imali eyongeziweyo ye-CMC yindlela ethe ngqo yokulawula i-viscosity ye-glaze slurry. Ukongeza i-CMC encinci kuya kubangela i-viscosity ephantsi ye-glaze, ngelixa ukwandisa inani le-CMC elongezelelweyo kuya kwandisa kakhulu i-viscosity. Kwimveliso yangempela, inani le-CMC elongezelelweyo lihlala liphakathi kwe-0.5% kunye ne-3%, ilungelelaniswe ngokweemfuno ezithile.
3. Izinto ezichaphazela ukukhethwa kwe-CMC viscosity
Xa ukhetha i-CMC, ezinye izinto ezinempembelelo kufuneka ziqwalaselwe:
a. Ukuqulunqwa kwe-glaze
Ukubunjwa kwe-glaze kuya kuthintela ngokuthe ngqo iimfuno zayo ze-viscosity. Ngokomzekelo, i-glazes enexabiso elikhulu lomgubo ococekileyo unokufuna i-thickener kunye ne-viscosity ephezulu ukugcina ukumiswa kakuhle. Iiglaze ezinamasuntswana amahle kakhulu zinokungadingi i-viscosity ephezulu kakhulu.
b. Ubungakanani besuntswana elikhazimlayo
Iiglaze ezinobuhle obuphezulu zifuna ukuba i-CMC ibe neepropati ezingcono zokujiya ukuze kuqinisekiswe ukuba amasuntswana acolekileyo anokunqunyanyiswa ngokulinganayo kulwelo. Ukuba i-viscosity ye-CMC ayanelanga, i-powder powder inokuthi iqhube, ibangele i-glaze engalinganiyo.
c. Ukuqina kwamanzi
Ukuqina kwamanzi kunempembelelo ethile kwi-solubility kunye nesiphumo sokuqina kwe-CMC. Ubukho be-calcium eyongezelelekileyo kunye ne-magnesium ion kumanzi anzima kunokunciphisa isiphumo sokujiya kwe-CMC kwaye kubangele imvula. Xa usebenzisa amanzi anzima, kunokufuneka ukhethe iintlobo ezithile ze-CMC ukusombulula le ngxaki.
d. Ubushushu bokusebenza kunye nokufuma
Ubushushu obuhlukeneyo bendawo yokusebenza kunye nokufuma kuya kuchaphazela i-viscosity ye-CMC. Umzekelo, kwindawo yobushushu obuphezulu, amanzi aphuphuma ngokukhawuleza, kwaye i-CMC ye-viscosity ephantsi inokufuneka ukunqanda ukujiya ngokugqithisileyo kwe-glaze slurry. Ngokuchasene noko, indawo yokushisa ephantsi inokufuna i-viscosity ephezulu ye-CMC ukuqinisekisa ukuzinza kunye nobuninzi be-slurry.
4. Ukhetho olusebenzayo nolungiselelo lwe-CMC
Kusetyenziso lwenene, ukhetho kunye nolungiselelo lweCMC kufuneka lwenziwe ngokwala manyathelo alandelayo:
Ukukhethwa kohlobo lwe-AnxinCel®CMC: Okokuqala, khetha uhlobo olufanelekileyo lweCMC. Kukho amabanga ahlukeneyo e-viscosity ye-CMC kwimarike, enokukhethwa ngokweemfuno ze-viscosity kunye neemfuno zokunqunyanyiswa kwe-glaze slurry. Umzekelo, ubunzima bemolekyuli ephantsi i-CMC ifanelekile kwi-glaze slurries efuna i-viscosity ephantsi, ngelixa ubunzima be-molecular CMC bufanelekile kwi-glaze slurries efuna i-viscosity ephezulu.
Uhlengahlengiso lovavanyo lwe-viscosity: Ngokweemfuno ze-glaze slurry, isixa se-CMC esongeziweyo sihlengahlengiswa ngokomfuniselo. Indlela eqhelekileyo yovavanyo kukongeza ngokuthe ngcembe i-CMC kunye nokulinganisa i-viscosity yayo de kufikelelwe kuluhlu lwe-viscosity olufunwayo.
Ukubeka iliso ukuzinza kwe-glaze slurry: I-glaze slurry elungisiweyo idinga ukushiywa ukuze ime ixesha elithile ukujonga ukuzinza kwayo. Jonga imvula, iagglomeration, njl.njl. Ukuba kukho ingxaki, isixa okanye uhlobo lweCMC lunokufuneka luhlengahlengiswe.
Lungisa ezinye izongezo: Xa usebenzisaCMC, kwakhona kuyimfuneko ukuqwalasela ukusetyenziswa kwezinye izongezo, ezifana ne-dispersants, i-level agents, njl. Ezi zongezo zinokusebenzisana ne-CMC kwaye zichaphazele umphumo wayo wokuqina. Ngoko ke, xa uhlengahlengisa i-CMC, kuyafuneka ukuba ubeke ingqalelo kumlinganiselo wezinye izongezo.
Ukusetyenziswa kwe-CMC kwi-ceramic glaze slurry ngumsebenzi wobugcisa obuphezulu, ofuna ukuqwalaselwa ngokubanzi kunye nohlengahlengiso olusekwe kwiimfuno ze-viscosity, ukubunjwa, ubungakanani bamasuntswana, indawo yokusetyenziswa kunye nezinye izinto ze-glaze slurry. Ukukhetha okunengqiqo kunye nokongezwa kwe-AnxinCel®CMC ayikwazi nje ukuphucula ukuzinza kunye nokuguquguquka kwe-glaze slurry, kodwa nokuphucula umphumo wokugqibela we-glaze. Ke ngoko, ukunyusa ngokuqhubekayo kunye nokulungelelanisa usetyenziso lwefomula yeCMC kwimveliso sisitshixo sokuqinisekisa umgangatho weemveliso zeceramic.
