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 kodongwe, 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.
