Impembelelo yeCarboxymethyl Cellulose (CMC) kwiiPropati zeCeramic Slurry

ICarboxymethyl cellulose (CMC) yipolymer enyibilikayo emanzini ephuma kwiselulosi enoluhlu olubanzi lwezicelo kumashishini ahlukeneyo.Kushishino lweeseramics, i-CMC isoloko isetyenziswa njengesibophelelo kunye nesilungisi se-rheology kwi-ceramic slurry formulations.Ukongezwa kwe-CMC kunokuchaphazela kakhulu iipropati ze-ceramic slurry, kuquka i-viscosity yayo, ukuziphatha kwe-rheological, kunye nokuzinza.Kweli nqaku, siza kuxubusha impembelelo yeCMC kwiipropati ze-ceramic slurry.

Viscosity

Ukongezwa kwe-CMC kwi-ceramic slurry kunokunyusa kakhulu i-viscosity yayo.Oku kubangelwa ubunzima obuphezulu bemolekyuli kunye neqondo eliphezulu lokutshintshwa kwe-CMC, okukhokelela kwi-viscosity ephezulu nakwiindawo eziphantsi.I-CMC isebenza njenge-ejenti yokuqina, inyusa i-viscosity ye-ceramic slurry kunye nokuphucula ukukwazi kwayo ukunamathela kumphezulu womzimba we-ceramic.

Ukuziphatha ngokweRheological

I-CMC inokuphembelela indlela yokuziphatha ye-rheological ye-ceramic slurry.I-rheology ye-ceramic slurry ibalulekile ekusebenzeni kwayo kunye nokusebenza kwayo.Ukongezwa kwe-CMC kunokubangela ukuziphatha okuchetywayo, apho i-viscosity ye-slurry iyancipha njengoko izinga lokucheba linyuka.Oku kunokuba luncedo ekuqhubeni, njengoko ivumela i-slurry ukuba ihambe ngokulula ngakumbi ngexesha lokuphosa, ukubumba, okanye ukugquma.Ukuziphatha kwe-rheological ye-slurry nako kunokuphenjelelwa kugxininiso, ubunzima bemolekyuli, kunye neqondo lokuthatha indawo ye-CMC.

Uzinzo

I-CMC inokuphucula ukuzinza kwe-ceramic slurry ngokuthintela ukuhlalisa okanye ukwahlula amasuntswana.Ukongezwa kwe-CMC kunokudala ukumiswa okuzinzileyo ngokunyusa i-viscosity ye-slurry, ukuphucula amandla ayo okubamba amaqhekeza ekumisweni.Oku kubaluleke kakhulu kwizicelo apho i-slurry idinga ukugcinwa okanye ukuhanjiswa kwimigama emide, njengoko ukuhlaliswa okanye ukuhlukana kunokubangela ukugquma okungafaniyo okanye ukudubula okungahambelaniyo.

Ukuhambelana

Ukuhambelana kweCMC kunye namanye amacandelo odaka lweceramic lukwayinto ebalulekileyo eqwalaselwayo.I-CMC inokunxibelelana namanye amacandelo, njengodongwe, i-feldspars, kunye nezinye izibophelelo, ezichaphazela iipropati kunye nokusebenza kwazo.Umzekelo, ukongezwa kwe-CMC kunokuphucula iimpawu zokubophelela zodongwe, okukhokelela kwimizimba ye-ceramic eyomeleleyo kunye neyomelele ngakumbi.Nangona kunjalo, izixa ezigqithisileyo ze-CMC zinokukhokelela kudaka olushinyeneyo, olukhokelela kubunzima bokucubungula kunye nokusetyenziswa.

Umthamo

Idosi ye-CMC kwi-ceramic slurry yinto ebalulekileyo ekufuneka iqwalaselwe.Elona xabiso liphezulu le-CMC liya kuxhomekeka kwisicelo esithile, kunye neepropati zoludaka kunye nokusebenza okufunayo.Ngokubanzi, ukuxinwa kwe-CMC kwi-ceramic slurry inokuqala ukusuka kwi-0.1% ukuya kwi-1%, kuxhomekeke kwisicelo.Uxinzelelo oluphezulu lwe-CMC lunokubangela udaka olutyebileyo noluzinze ngakumbi, kodwa lunokukhokelela kubunzima ekusetyenzweni nasekusetyenzisweni.

Ukuqukumbela

Ngamafutshane, i-CMC inokuchaphazela kakhulu iipropathi ze-ceramic slurry, kubandakanya i-viscosity yayo, i-rheological behaviour, uzinzo, ukuhambelana, kunye nedosi.Ngokuqonda impembelelo ye-CMC kwezi zakhiwo, kuyenzeka ukuba kunyuswe ukusebenza kwe-ceramic slurry kwizicelo ezahlukeneyo, njengokuphosa, ukubumba, ukugquma, okanye ukuprinta.Ukusetyenziswa kwe-CMC kwi-ceramic slurry formulations kunokubangela ukuphuculwa kokusetyenzwa, ukusebenza, kunye nokuqina kweemveliso ze-ceramic.
