I-CMC isebenzisa embonini ye-Ceramic

I-sodium carboxymethyl cellulose, isifinyezo sesiNgisi i-CMC, imboni ye-ceramic yaziwa kakhulu ngokuthi “I-Sodium CMC", iwuhlobo lwento ye-anionic, yenziwe nge-cellulose yemvelo njengempahla eluhlaza, ngokuguqulwa kwamakhemikhali kanye nempushana emhlophe noma ephuzi ekhanyayo. I-CMC inokunyibilika okuhle futhi ingancibilika ibe yisixazululo esisobala nesifanayo kuwo womabili amanzi abandayo nashisayo.

1. Ukwethulwa kafushane kwe-CMCisebenzisa ku-ceramics

1.1 ukusetshenziswa kwe-CMC kuma-ceramics

1.1.1. Umgomo wohlelo lokusebenza

I-CMC inesakhiwo se-polymer esiyingqayizivele. Lapho i-CMC yengezwa emanzini, iqembu layo le-hydrophilic (-Coona) lihlanganiswa namanzi ukuze lenze ungqimba oluncibilikisiwe, oluhlakaza kancane kancane ama-molecule e-CMC emanzini. Isakhiwo senethiwekhi phakathi kwama-CMC polymers sakhiwe ngebhondi ye-hydrogen namandla e-van der Waals, ngaleyo ndlela kukhombisa ukuhlangana. I-CMC eqondene nomzimba ingasetshenziswa njenge-excipient, plasticizer kanye ne-reinforcer ye-billet embonini yobumba. Ukwengeza inani elifanele le-CMC ku-billet kungakhuphula amandla okubopha ku-billet, kwenze i-billet yakheke kalula, kwandise amandla okuguquguquka izikhathi ezingu-2 ~ 3, futhi kuthuthukise ukuzinza kwe-billet, ukuze kuthuthukiswe izinga lekhwalithi ye-billet. Ceramics, ukunciphisa izindleko zokucubungula kamuva. Ngesikhathi esifanayo, ngenxa yokwengezwa kwe-CMC, isivinini sokucubungula se-billet eluhlaza singathuthukiswa futhi ukusetshenziswa kwamandla okukhiqiza kungancishiswa, futhi amanzi ku-billet angahwamuka ngokulinganayo ukuvimbela ukoma nokuqhekeka, ikakhulukazi ngobukhulu obukhulu. ye-tile billet yaphansi kanye ne-billet yezitini eziphucuziwe, umphumela ubonakala ngokucacile. Uma kuqhathaniswa namanye ama-ejenti aqinisa umzimba, i-CMC ethile yomzimba inezici ezilandelayo:

(1) umthamo omncane: umthamo ngokuvamile ungaphansi kuka-0.1%, okuyi-1/5 ~ 1/3 yenye i-ejenti yokuqinisa umzimba, kuyilapho amandla okugoba omzimba oluhlaza esobala futhi izindleko zingancishiswa.

(2) ukulahlekelwa okuhle kokushiswa: ngemva kokushisa cishe akukho mlotha, akukho nsalela, akuphazamisi umbala oluhlaza.

(3) ngokumiswa okuhle: ukuvimbela izinto zokusetshenziswa abampofu kanye nemvula uginindela, ukuze udaka ngokulinganayo bahlakazeka.

(4) Ukumelana nokugqoka: ohlelweni lokugaya ibhola, iketango lamangqamuzana alimala kancane.

1.1.2. Indlela yokwengeza

Inani elijwayelekile le-CMC ku-billet ngu-0.03 ~ 0.3%, elingalungiswa ngokuvumelana nezidingo zangempela. Ngodaka olunezinto eziningi eziluhlaza ezingezinhle kufomula, i-CMC ingangezwa emshinini webhola futhi igaywe kanye nodaka, inake ukuhlakazeka komfaniswano, ukuze kungabi nzima ukukuncibilikisa ngemuva kokuhlanganiswa, noma i-CMC ingakwazi. zincibilike ngaphambili ngamanzi ngo-1:30 ngokwehlukana bese zengezwa emshinini wokugaya ukuze kuxutshwe amahora angu-1 ~ 5 ngaphambi kokugaya.

1.2. Ukusetshenziswa kwe-CMC ku-glaze slurry

1.2.1 Umgomo wohlelo lokusebenza

I-Glaze Namathisela ekhethekile I-TYPE CMC iyisinzisi sokusebenza esihle kakhulu nesibopho, esetshenziselwa ukucwebezela okuphansi kwethayela le-ceramic kanye nokucwebezela kwendawo, ingakhuphula amandla okubopha okucwebezelayo okucwebezelayo nomzimba, ngoba ubucwebe obucwebezelayo bunemvula kalula futhi bungazinzi kahle, kanye ne-CMC nazo zonke izinhlobo ze-glaze slurry. ukuhambisana kwe-glaze kuhle, kunokuhlakazeka okuhle kakhulu kanye ne-colloid evikelayo, ukuze umzimba ocwebezelayo ube uzinzile kakhulu. isimo sokuhlakazeka. Ngemuva kokwengeza i-CMC, ukushuba kwesicwebezelisi kungathuthukiswa, amanzi angavinjelwa ukuthi angahlukani nokucwebezela emzimbeni, ubushelelezi be-glaze bungandiswa, ukuqhekeka nokuqhekeka okubangelwa ukwehla kwamandla omzimba ngemuva kokwengeza i-CMC. ukusetshenziswa kwe-glaze kungagwenywa, futhi i-pinhole phenomenon ye-glaze nayo ingancishiswa ngemva kokubhaka.

1.2.2. Indlela yokwengeza

Inani le-CMC elingezwe ku-glaze engezansi kanye nokucwebezela okungaphezulu lisuka ku-0.08 liye ku-0.30%. Ingalungiswa ngokuvumelana nezidingo zangempela. Okokuqala, i-CMC ilungiswa ibe yisisombululo esinamanzi esingu-3%. Uma idinga ukugcinwa izinsuku ezimbalwa, ikhambi kufanele lifakwe esitsheni esingangeni moya esinama-preservatives afanelekile futhi sigcinwe ekushiseni okuphansi. Khona-ke, isisombululo sixubene ngokulinganayo ne-glaze.

1.3 Ukusetshenziswa kwe-CMC ekuphrinteni okucwebezelayo

1.3.1, ukuphrinta okucwebezelayo okukhethekile kwe-CMC inendawo enhle yokuqina nokuhlakazeka nokuzinza, i-CMC ekhethekile yokwamukela ubuchwepheshe obusha, ukuncibilika okuhle, obala okuphezulu, cishe awekho ama-insolubles, kodwa futhi inokucwebezela okuphakeme okucwebezelayo nokugcobisa, ithuthukise kakhulu ukuphrinta okucwebezelayo. ukuzivumelanisa nezimo, ukunciphisa isikrini, ukwenzeka kokuvinjwa kwesikrini, ukunciphisa izikhathi zenethiwekhi, lapho uphrinta ukusebenza okushelelayo, Sula iphethini, ukuhambisana kahle kombala.

1.3.2 Inani elijwayelekile lokwengeza iglaze yokuphrinta ngu-1.5-3%. I-CMC ingacwiliswa nge-ethylene glycol bese ifakwa ngamanzi ukuze ikwazi ukutholakala, noma i-1-5% ye-sodium tripolyphosphate nezinto zombala zingaba zomile zixutshwe ndawonye, ​​​​bese zichithwa ngamanzi, ukuze izinto ezihlukahlukene zihlakazwe ngokugcwele futhi zilingane.

1.4. Ukusetshenziswa kwe-CMC ku-glaze yokungena

1.4.1 Umgomo wohlelo lokusebenza

Ukungena okucwebezelayo kuqukethe usawoti omningi oncibilikayo, i-asidi, kanye ne-glaze ethile yokungena okukhethekile kwe-CMC ine-acidity ephakeme yokumelana nosawoti, yenza i-glaze yokungena ohlelweni lokusetshenziswa nokubekwa igcine i-viscosity ezinzile, ivimbele ngenxa yezinguquko ze-viscosity, umbala kanye i-penetration glaze ekhethekile ye-CMC encibilikayo emanzini, ukungena kwenetha nokugcinwa kwamanzi kuhle kakhulu, ukugcina ukuzinza kosawoti oncibilikayo. I-glaze inosizo olukhulu.

1.4.2. Indlela yokwengeza

Chaza i-CMC nge-ethylene glycol, amanzi athile kanye ne-ejenti eyinkimbinkimbi, bese uxuba kahle nesixazululo sombala esincibilikisiwe.

I-2.CMC kufanele inakwe ekukhiqizeni kwe-ceramic

2.1 Izinhlobo ezahlukene ze-CMC zidlala izindima ezihlukene ekukhiqizweni kobumba. Ukukhetha okufanele kungafeza inhloso yomnotho nokusebenza kahle.

2.2. Ku-glaze nokuphrinta okucwebezelayo, akudingekile ukuhlanganisa imikhiqizo ye-CMC ngobumsulwa obuphansi, ikakhulukazi ku-glaze yokuphrinta, ukuhlanzeka okuphezulu kwe-CMC enokuhlanzeka okuphezulu, ukumelana ne-asidi enhle nosawoti kanye nokucaca okuphezulu kufanele kukhethwe ukuvimbela ama-ripples namaphinikhodi ku-glaze. cwebezela. Ngesikhathi esifanayo, kungavimbela ukusetshenziswa kwe-plug net, izinga eliphansi nombala nezinye izenzakalo.

2.3 Uma izinga lokushisa liphezulu noma i-glaze idinga ukubekwa isikhathi eside, ama-preservatives kufanele afakwe.

3. Ukuhlaziywa kwezinkinga ezivamile ze-CMC ekukhiqizeni kwe-ceramic

3.1. I-fluidity yodaka ayilungile futhi kunzima ukubeka i-glue.

Ngenxa ye-viscosity ye-CMC ngokwayo, i-viscosity yodaka iphezulu kakhulu, okuholela ebunzimeni be-pulping. Isixazululo ukulungisa inani kanye nohlobo lwe-coagulant, batusa ifomula elandelayo ye-decoagulant1) i-sodium tripolyphosphate 0.3%; (2) i-tripolyphosphate ye-sodium 0.1% + i-sodium silicate 0.3%; (3) I-sodium humate 0.2%+ sodium tripolyphosphate 0.1%

3.2. I-glaze paste namafutha okuphrinta mancane.

Izizathu zokukhetha i-glaze paste namafutha wokuphrinta zimi kanje1) unamathisele ocwebezelayo noma uwoyela wokuphrinta ugugulwa ama-microorganisms, ukuze i-CMC yehluleke. Isixazululo ukugeza isitsha se-glaze paste noma uwoyela wokuphrinta kahle, noma wengeze izinto zokuvikela ezifana ne-formaldehyde ne-phenol. (2) Ngaphansi kokunyakaziswa okuqhubekayo kwamandla okugunda, i-viscosity iyancipha. Kunconywa ukulungisa isixazululo samanzi se-CMC.

3.3. Namathisela i-mesh uma usebenzisa i-glaze yokuphrinta.

Isixazululo ukulungisa inani le-CMC, ukuze i-viscosity ye-glaze yokunyathelisa ibe ngokulinganisela, uma kunesidingo, engeza inani elincane lamanzi ukuze uqhube ngokulinganayo.

3.4, ukuvimbela inethiwekhi, sula inani lezikhathi.

Isixazululo ukwenza ngcono ukubonakala nokunyibilika kwe-CMC. Ukulungiswa kwamafutha okuphrinta ngemuva kokuphothulwa kwe-120 mesh sieve, uwoyela wokuphrinta nawo udinga ukudlula isisefo se-100 ~ 120 mesh; Lungisa ukuphrinta kwe-glaze viscosity.

3.5, ukugcinwa kwamanzi akukuhle, ngemva kokunyathelisa ufulawa ongaphezulu, kuthinta ukuphrinta okulandelayo.

Isixazululo ukwandisa inani le-glycerin ohlelweni lokunyathelisa ukulungiswa kwamafutha; Shintshela ezingeni eliphezulu lokushintsha (shintshanisa ukufana okuhle), i-viscosity ephansi ye-CMC ukuze ulungiselele uwoyela wokuphrinta.
