I-CMC isebenzisa kuShishino lweCeramic

I-sodium carboxymethyl cellulose, isifinyezo sesiNgesi CMC, ishishini leceramic liyaziwa ngokuba "Sodium CMC", luhlobo lwe-anionic substance, yenziwe nge-cellulose yendalo njengento ekrwada, ngokuguqulwa kweekhemikhali kunye nomgubo omhlophe okanye okhanyayo ophuzi. I-CMC inokunyibilika okulungileyo kwaye inokunyibilikiswa kwisisombululo esicacileyo nesifanayo kumanzi abandayo nashushu.

1. Intshayelelo emfutshane yeCMCusebenzisa kwiiseramics

1.1 Ukusetyenziswa kweCMC kwiiseramikhi

1.1.1. Umgaqo wokusetyenziswa

I-CMC inolwakhiwo olulodwa lwepolymer emgceni. Xa i-CMC yongezwa emanzini, iqela layo le-hydrophilic (-Coona) lidityaniswe namanzi ukwenza umaleko onyibilikisiweyo, othi ngokuthe ngcembe usasaze iimolekyuli zeCMC emanzini. Ubume bothungelwano phakathi kweepholima ze-CMC zenziwa yi-hydrogen bond kunye ne-van der Waals force, ngaloo ndlela ibonisa ukuhambelana. Umzimba othe ngqo we-CMC unokusetyenziswa njenge-excipient, i-plasticizer kunye ne-reinforcer ye-billet kwishishini le-ceramic. Ukongeza inani elifanelekileyo le-CMC kwi-billet kunokunyusa amandla okubambisana kwe-billet, yenza i-billet ibe lula ukwenza, ukwandisa amandla okuguquguquka ngama-2 ~ 3 amaxesha, kunye nokuphucula ukuzinza kwe-billet, ukwenzela ukuba kuphuculwe izinga lomgangatho we-billet. ii-ceramics, ukunciphisa iindleko zokucutshungulwa kamva. Ngelo xesha, ngenxa yokongezwa kwe-CMC, isantya sokucubungula i-billet eluhlaza singaphuculwa kwaye ukusetyenziswa kwamandla okuvelisa kungancitshiswa, kwaye amanzi kwi-billet anokuthi aguqulwe ngokulinganayo ukukhusela ukoma kunye nokuqhekeka, ngokukodwa kubukhulu obukhulu. yomgangatho we-tile billet kunye ne-billet yezitena eziphuculweyo, umphumo ubonakala ngakumbi. Xa kuthelekiswa nezinye ii-arhente zokomeleza umzimba, i-CMC ejongene nomzimba inezi mpawu zilandelayo:

(1) i-dosage encinci: idosi ngokubanzi ingaphantsi kwe-0.1%, eyi-1/5 ~ 1/3 yenye i-agent yokomeleza umzimba, ngelixa amandla okugoba omzimba oluhlaza kubonakala kwaye iindleko zinokuncitshiswa.

(2) ilahleko elungileyo yokutshisa: emva kokutshisa phantse akukho mlotha, akukho ntsalela, ayichaphazeli umbala oluhlaza.

3

(4) Ukugqoka ukuxhathisa: kwinkqubo yokugaya ibhola, ikhonkco le-molecular lilonakaliswe kancinci.

1.1.2. Indlela yokongeza

Isixa esiqhelekileyo se-CMC kwi-billet yi-0.03 ~ 0.3%, enokuthi ihlengahlengiswe ngokweemfuno zangempela. Kuba uludaka olunezinto ezininzi ezihluphekayo ekrwada kwifomula, iCMC inokongezwa kwilitye lokusila kunye nomhlaba kunye nodaka, nikela ingqalelo kwiyunifomu yokusasazwa, ukuze kungabikho nzima ukunyibilika emva kokuhlanganiswa, okanye i-CMC inako. zinyibilikiswe ngaphambili ngamanzi ngo-1:30 ngokwahlukileyo kwaye emva koko zongezwe kwi-mill yebhola yokuxuba i-1 ~ 5 iiyure ngaphambi kokusila.

1.2. Ukusetyenziswa kwe-CMC kwi-glaze slurry

1.2.1 Umgaqo wokusetyenziswa

I-Glaze paste ekhethekileyo UHLOBO lwe-CMC lugqwesile ukusebenza ngokuzinzisa kunye nesibophelelo, esisetyenziselwa i-ceramic ithayile esezantsi ecwebezelayo kunye nomkhenkce womphezulu, unokonyusa amandla okubopha i-glaze slurry kunye nomzimba, kuba i-glaze slurry ilula kwimvula kunye nozinzo olulambathayo, kunye neCMC kunye nazo zonke iintlobo Ukuhambelana kwe-glaze kulungile, kunokusasazwa okugqwesileyo kunye ne-colloid ekhuselayo, ukuze umzimba we-glaze ukwimeko ezinzileyo yokusasazwa. Emva kokongeza i-CMC, ukunyanzeliswa komphezulu we-glaze kunokuphuculwa, amanzi anokuthintelwa ukuba asasazeke ukusuka kwi-glaze ukuya emzimbeni, ukugudisa kweglaze kunokonyuka, ukuqhekeka kunye nokuqhekeka okwenzekayo okubangelwa kukuhla kwamandla omzimba emva kokunciphisa i-glaze. Ukusetyenziswa kwe-glaze kunokuphetshwa, kwaye i-pinhole phenomenon ye-glaze nayo ingancitshiswa emva kokubhaka.

1.2.2. Indlela yokongeza

Isixa se-CMC esongezwe kwi-glaze esezantsi kunye ne-glaze yomhlaba ukusuka kwi-0.08 ukuya kwi-0.30%. Inokulungiswa ngokweemfuno zokwenyani. Okokuqala, i-CMC ilungiswa ibe yi-3% yesisombululo samanzi. Ukuba kufuneka igcinwe iintsuku eziliqela, isisombululo kufuneka sifakwe kwisitya esingenawo umoya kunye nezigcinayo ezifanelekileyo kwaye zigcinwe kwiqondo lokushisa eliphantsi. Emva koko, isisombululo sixutywe ngokulinganayo kunye ne-glaze.

1.3 Ukusetyenziswa kwe-CMC kushicilelo lweglaze

1.3.1, ushicilelo olucwebezelayo olukhethekileyo lweCMC lunepropathi elungileyo yokuqina kunye nokusasazeka kunye nozinzo, i-CMC ekhethekileyo yamkele itekhnoloji entsha, ukunyibilika okuhle, ukucaca okuphezulu, phantse akukho i-insolubles, kodwa ikwanakho ukucheba okuphezulu kunye nokuthambisa, ukuphucula kakhulu ushicilelo lweglaze. ukuguquguquka, ukunciphisa isikrini, into yokuthintela isikrini, ukunciphisa amaxesha othungelwano, xa ushicilela ukusebenza kakuhle, ipateni ecacileyo, ukuhambelana kombala okulungileyo.

1.3.2 Isixa esiqhelekileyo sokongeza i-glaze yokushicilela yi-1.5-3%. I-CMC inokuxutywa kunye ne-ethylene glycol kwaye yongezwe ngamanzi ukuyenza i-presoluble, okanye i-1-5% ye-sodium tripolyphosphate kunye nezixhobo zombala zinokoma zixutywe kunye, kwaye zinyibilikiswe ngamanzi, ukuze izinto ezahlukeneyo zinyibilike ngokupheleleyo kwaye zilungelelaniswe.

1.4. Ukusetyenziswa kwe-CMC kwi-glaze yokungena

1.4.1 Umgaqo wokusetyenziswa

Iglaze yokungena iqulethe ityuwa eninzi enyibilikayo, i-asidi, kunye nenxalenye ethile yokungena kwi-glaze ekhethekileyo ye-CMC ine-acidity ephezulu yokumelana netyuwa, yenza i-glaze yokungena kwinkqubo yokusetyenziswa kunye nokubekwa igcine i-viscosity ezinzileyo, ithintele ngenxa yokutshintsha kwe-viscosity, umbala kunye ukungena glaze ekhethekileyo CMC amanzi enyibilikayo, permeability net kunye nokugcinwa kwamanzi kuhle kakhulu, ukugcina uzinzo ityuwa glaze enyibilikayo unoncedo oluninzi .

1.4.2. Indlela yokongeza

Dissolve CMC kunye ne-ethylene glycol, amanzi athile kunye ne-agent eyinkimbinkimbi, emva koko udibanise kakuhle kunye nesisombululo sombala esinyibilikisiweyo.

I-2.CMC kufuneka ithathelwe ingqalelo kwimveliso ye-ceramic

2.1 Iindidi ezahlukeneyo ze-CMC zidlala indima eyahlukileyo kwimveliso ye-ceramic. Ukukhetha okufanelekileyo kunokufezekisa injongo yoqoqosho kunye nokusebenza kakuhle.

2.2. Kwi-glaze kunye noshicilelo lweglaze, akuyomfuneko ukuba ucofe iimveliso ze-CMC ngobunyulu obuphantsi, ngakumbi kwi-glaze yoshicilelo, ukucoceka okuphezulu kwe-CMC kunye nokucoceka okuphezulu, ukuxhathisa okuhle kwe-asidi kunye netyuwa kunye nokucaca okuphezulu kufuneka kukhethwe ukukhusela ama-ripples kunye neepinholes ukumenyezela. Kwangaxeshanye, kunokuthintela ukusetyenziswa komnatha weplagi, umgangatho ombi kunye nombala kunye nezinye izinto.

2.3 Ukuba iqondo lokushisa liphezulu okanye i-glaze ifuna ukubekwa ixesha elide, ii-preservatives kufuneka zongezwe.

3. Uhlalutyo lweengxaki eziqhelekileyo ze-CMC kwimveliso ye-ceramic

3.1. Ubumanzi bodaka akulunganga kwaye kunzima ukubeka iglu.

Ngenxa ye-viscosity ye-CMC ngokwayo, i-viscosity yodaka iphezulu kakhulu, ekhokelela kubunzima be-pulping. Isisombululo kukulungelelanisa inani kunye nohlobo lwe-coagulant, ncoma le fomula ye-decoagulant elandelayo1) i-sodium tripolyphosphate 0.3%; (2) i-sodium tripolyphosphate 0.1% + i-sodium silicate 0.3%; (3) I-sodium humate 0.2% + i-sodium tripolyphosphate 0.1%

3.2. I-glaze paste kunye neoyile yokushicilela zincinci.

Izizathu zokukhetha i-glaze paste kunye neoli yokushicilela zilandelayo1) i-glaze paste okanye ioli yokushicilela ichithwa yi-microorganisms, ukuze i-CMC iphumelele. Isisombululo kukuhlamba i-container ye-glaze paste okanye i-oyile yokushicilela ngokucokisekileyo, okanye ukongeza izigcini ezifana ne-formaldehyde kunye ne-phenol. (2) Ngaphantsi kokuvuselela okuqhubekayo kwamandla okucheba, i-viscosity iyancipha. Kuyacetyiswa ukuba uhlengahlengise isisombululo samanzi se-CMC.

3.3. Ncamathelisa umnatha xa usebenzisa iglaze yokushicilela.

Isisombululo kukulungelelanisa inani le-CMC, ukwenzela ukuba i-viscosity ye-glaze yokushicilela imodareyitha, ukuba kuyimfuneko, yongeza inani elincinci lamanzi ukuze liqhube ngokulinganayo.

3.4, ukuvala inethiwekhi, sula inani lamaxesha.

Isisombululo kukuphucula ukungafihli kunye nokunyibilika kweCMC. Ukulungiswa kweoli yokuprinta emva kokugqitywa kwe-120 mesh sieve, ioli yokuprinta nayo kufuneka idlule i-100 ~ 120 mesh sieve; Lungisa ushicilelo lwe-viscosity ye-glaze.

3.5, ukugcinwa kwamanzi akulungile, emva kokushicilela umgubo ongaphezulu, kuchaphazela ukuprintwa okulandelayo.

Isisombululo kukunyusa inani le-glycerin kwinkqubo yokushicilela ukulungiswa kweoli; Tshintshela kwiqondo eliphezulu lokuthatha indawo (ukubuyisela ukufana okuhle), i-viscosity ephantsi ye-CMC ukulungiselela ioli yokushicilela.
