Ukusetshenziswa kwe-sodium carboxymethyl cellulose (CMC) kuma-ceramics

I-Sodium carboxymethyl cellulose, isifinyezo sesiNgisi, esaziwa kakhulu ngokuthi "methyl" embonini ye-ceramic, yinto ye-anionic, i-powder emhlophe noma ephuzi kancane eyenziwe nge-cellulose yemvelo njengoba iguqulwe ngamakhembu. . I-CMC ine-soubelity enhle futhi ingachithwa kusisombululo esibonakalayo esibonakalayo esibonakalayo emanzi abandayo namanzi ashisayo.

1. Isingeniso esifushane ekusetshenzisweni kwe-CMC kuma-ceramics
1.1. Ukusetshenziswa kwe-CMC kuma-ceramics
1.1.1, Isimiso sohlelo lokusebenza
I-CMC inesakhiwo esihlukile se-polymer. Lapho i-CMC yengezwa emanzini, iqembu layo le-hydrophilic (-Coona) lihlanganisa ngamanzi ukwakha i-waller yodwa, ukuze ama-molecule we-CMC ahlakazwa kancane kancane emanzini. I-CMC polymers incike kuma-hydrogen bond kanye namabutho we-van der Waals. Umphumela wenza isakhiwo senethiwekhi, ngaleyo ndlela sibonisa ubumbano. I-CMC eqondene nomzimba ingasetshenziswa njenge-excipient, i-spitizer, kanye ne-ejenti eqinisayo yemizimba eluhlaza embonini ye-ceramic. Ukungeza inani elifanele le-CMC ku-billet kungakhuphula amandla abumbanayo we-billet, yenza i-billet ibe lula ukwakha, bese ithuthukisa ukuqina komkhiqizo we-ceramics kanye nokunciphisa izindleko zokucubungula. . Ngasikhathi sinye, ngenxa yokwengeza i-CMC, kungandisa isivinini sokucubungula umzimba esiluhlaza futhi kunciphise ukusetshenziswa kwamandla okukhiqizwayo. Kungenza futhi umswakama ku-Billet efulawa ngokulinganayo futhi uvikele ukomisa nokuqhekeka. Ikakhulu uma isetshenziswa kuma-tile ama-tile asayizi amakhulu kanye namabhili wezitini acwebezelayo, umphumela ungcono kakhulu. kusobala. Uma kuqhathaniswa namanye ama-ejenti wokuqinisa umzimba weGreen Green, umzimba okhethekile weGreen CMC unezici ezilandelayo:

(1) Inani elincane lokungezwa
(2) Impahla enhle yokushiswa: cishe akekho umlotha osele ngemuva kokuvutha, futhi akukho okusalayo, okungathinti umbala ongenalutho.
.
.

1.1.2, Ukungeza Indlela
Inani lesengezo elijwayelekile le-CMC ku-billet lingu-0.03-0.3%, elingashintshwa ngokufanele ngokwezidingo zangempela. Oda udaka olunezinto eziningi zokusetshenziswa ezibuthakathaka kwifomula, i-CMC ingangezwa ku-Ball Mill ukugaya kanye nodaka, noma ukuncibilikisa i-CMC, ukuze ingabi nzima ukuncibilikisa i-agglomeration, noma kungabi nzima ukuncibilikisa i-AGGGORY,

1.2. Ukusetshenziswa kwe-CMC in Glaze Slurry

1.2.1. Inqubo yesicelo
I-CMC ye-Glaze Slurry iyi-stabilizer kanye ne-tinder ngokusebenza okuhle kakhulu. Isetshenziswa ku-glaze engezansi kanye ne-glaze ephezulu yamathayili e-ceramic, angakhuphula amandla okubopha phakathi kwe-glaze slurry nomzimba. Ngoba i-glaze slurry kulula ukuyicoca futhi inokuqina okungalungile, i-CMC kanye nokuhlukahluka kokuhambisana kwalolu hlobo lwe-glaze kuhle, futhi kuvikela kakhulu i-colloid enhle kakhulu, ukuze i-glaze iyisesimweni sokuhlakazeka kakhulu. Ngemuva kokungeza i-CMC, ukungezwani kwe-glaze kungandiswa, kungavikeleka amanzi kusuka ku-glaze emzimbeni oluhlaza, ubushelelezi be-glaze lingabangelwa ukwehla kwamandla komzimba oluhlaza ngemuva kokugcotshwa. , IPhinole Phecomenon e-glaze ebusweni nayo ingancishiswa ngemuva kokudubula.

1.2.2. Ukungeza indlela
Inani le-CMC elingezwe ku-glaze engezansi kanye ne-glaze ephezulu ngokuvamile i-0.08-0.30%, futhi ingashintshwa ngokuya ngezidingo zangempela ngesikhathi sokusetshenziswa. Okokuqala yenza i-CMC ibe yisisombululo esingamanzi esingu-3%. Uma kudinga ukugcinwa izinsuku eziningana, lesi sixazululo sidinga ukungezwa ngenani elifanele lezinto ezilondoloziwe futhi zibekwe esitsheni esivaliwe, zigcinwe emazingeni okushisa aphansi, bese kuxutshwa ne-glaze ngokulinganayo.

1.3. Ukusetshenziswa kwe-CMC ekuphrinte kwe-glaze

1.3.1. I-CMC ekhethekile yokuphrinta i-glaze inokuqina okuhle, ukungafani kanye nokuqina. Le CMC ekhethekile ye-CMC yamukela ubuchwepheshe obusha, ine-soubelity enhle, ukucaca okuphezulu, cishe akukho ndaba ekunciphisekile kwempahla nokugcoba, ukunciphisa inani lamasu wokuphrinta, ukunciphisa inamba yokuphrinta, ukuphrinta okubushelelezi ngesikhathi sokusebenza, kanye nokuguquguquka kombala okuhle.

1.3.2. Inani lokungezelela okujwayelekile lokungeza i-glaze yokuphrinta yi-1.5-3%. I-CMC ingangena ngaphakathi kwe-ethylene glycol bese wengeza amanzi ukuyenza ichithwe kuqala. Ingangezwa futhi nge-1-5% sodium tripolyphosphate kanye nezinto zokwakha imibala ndawonye. Ukuxuba okulomile, bese uchithwa ngamanzi, ukuze zonke izinhlobo zezinto zokwakha zingachithwa ngokugcwele ngokugcwele.

1.4. Ukusetshenziswa kwe-CMC ku-Oozing Glaze

1.4.1. Inqubo yesicelo
I-Breating Glaze iqukethe usawoti omningi oncibilikile, futhi ezinye zazo zinama-acidic kancane. Uhlobo olukhethekile lwe-CMC lwe-Glaze yegazi i-acid ne-acid enhle kakhulu kanye nokuqina kosawoti, okungagcina ukubonwa kokopha kwegazi ngesitebekile ngesikhathi sokusetshenziswa nokubekwa, futhi kuvikele ukuthi kulinyazwe ngenxa yezinguquko ekubonakaleni. Kuthinta umehluko wombala, kanye ne-solubility yamanzi, ukugcinwa kwamanzi kanye nokugcinwa kwamanzi kwe-CMC ekhethekile ye-glaze ephuma kahle kuhle kakhulu ukulondolozwa kokuqina kwe-glaloched.

1.4.2. Ngeza indlela
Dissolve CMC nge-ethylene glycol, ingxenye yamanzi kanye ne-ejenti yezinkinga kuqala, bese uxuba nesixazululo esincibilikisiwe.

2. Izinkinga okufanele zibhekwe ekukhiqizweni kwe-CMC kuma-ceramics

2.1. Izinhlobo ezahlukahlukene ze-CMC zinemisebenzi ehlukene ekukhiqizweni kwama-ceramics. Ukukhetha okulungile kungafinyelela inhloso yezomnotho nokusebenza kahle.

2.2. E-glaze surface kanye nokuphrinta, akumele usebenzise imikhiqizo ye-CMC ehlanzayo eshibhile, ikakhulukazi ekuphrintiwe, kufanele ukhethe i-CMC ebumsulwa, ukumelana nosawoti, nokubonakala okuphezulu ukuvikela phezulu. Ngasikhathi sinye, kungavimba futhi into yento yokuxhumanisa inetha, umkhawulo we-leveling nombala umehluko ngesikhathi sokusetshenziswa.
2.3. Uma izinga lokushisa liphezulu noma i-glish slurry idinga ukufakwa isikhathi eside, kufanele ingezwe.

3. Ukuhlaziywa kwezinkinga ezijwayelekile ze-CMC ekukhiqizeni i-Ceramic

3.1. U-fluidity odaka awumuhle, futhi kunzima ukukhulula i-glue.
Ngenxa yokubonakala kwayo, i-CMC izokwenza ukuthi ubuhlakani bodaka bube buphezulu kakhulu, okwenza kube nzima ukukhulula udaka. Isixazululo ukuguqula inani nohlobo lwe-coabulant. Kunconywe ifomula elilandelayo elihlonishwayo: (1) sodium tripolyphosphate 0.3%; (2) sodium tripolyphosphate 0.1% + Ingilazi yamanzi 0.3%; (3) I-Sumcon Acid Sodium 0.2% + sodium triplolyphosphate 0.1%

3.2. I-glirry slurry ne-inki yokuphrinta mncane.
Izizathu zokuthi kungani i-glish slurry ne-inki yokuphrinta zinciphile zimi kanjena: (1) I-glirry slurry noma i-inki yokuphrinta ikhishwe ama-microorganisms, okwenza i-cmc ilungiswe yi-microorganisms, eyenza i-CMC ingasebenzi. Isixazululo ukugeza ngokuphelele isitsha se-glaze slurry noma i-ink, noma engeza okulondoloziwe okufana ne-formaldehyde ne-phenol. (2) Ngaphansi kokushukumisa okuqhubekayo ngaphansi kwamandla we-shear, i-visa yehla. Kunconywa ukwengeza isisombululo samanzi se-CMC ukuze uguqule lapho usebenzisa.

3.3. Namathisela inetha lapho usebenzisa i-glaze yokuphrinta.
Isixazululo ukuguqula inani le-CMC ukuze i-viscosity ye-viscosity ye-glaze ephrinta ilinganiselwe, futhi uma kunesidingo, engeza inani elincane lamanzi ukuze livuse ngokulinganayo.

3.4. Kunezikhathi eziningi zokuvinjwa kwenethiwekhi nokuhlanza.
Isixazululo ukuthuthukisa ukuvela obala kanye ne-solubility ye-CMC; Ngemuva kokuba uwoyela wokuphrinta ulungiselelwe, dlula kuso u-120-mesh ngesihlungo, futhi uwoyela wokuphrinta nawo udinga ukudlula esihluthulweni sika-100-120-Mesh; Lungisa i-viscosity ye-glaze yokuphrinta.

3.5. Ukugcinwa kwamanzi akukuhle, futhi ingaphezulu lembali lizothuthukiswa ngemuva kokuphrinta, okuzothinta ukuphrinta okulandelayo.
Isixazululo ukukhulisa inani le-glycerin inqubo yokuphrinta uwoyela wokulungiselela; Sebenzisa i-SpecialScual ephakathi nesezingeni eliphansi nge-Phezulu esikhundleni sokufakwa esikhundleni se-High (ukufana okuhle) ukulungiselela uwoyela wokuphrinta.
