Igitekerezo Cyakazi
Kongera umwuka uremereye (SLA) hejuru yubushyuhe bwa 750-800 ° C, iyi nzira ituma sisitemu yo kugarura ubushyuhe bwinshi ikesha ibikoresho bya ceramic.Buri cyumba cyo kuvugurura kirimo materique ceramic, iyo, bitewe nicyerekezo cyogutemba, ikurura ubushyuhe buva mumyanda nyuma yo gutwikwa cyangwa gushyushya umwuka mbere yo gutwikwa.Ukurikije igipimo cy’imyanda ihumanya, igihingwa gishobora gukoresha iminara 3 cyangwa 5.Inzira itembera hejuru yuburiri mucyumba kimwe cyashyutswe mugihe cyabanje;uburiri bushyushya umwuka hafi yubushyuhe bwo gutwikwa, hafi 800 ° C, kandi muriki gihe ubushyuhe bwigitanda bugabanuka vuba.Ubushyuhe bwo gutwikwa bugumishwa nubushyuhe buturuka kuri okiside ya VOC cyangwa, niba VOC yibanze cyane, hiyongereyeho lisansi yingoboka.Umwuka wimyanda uva mucyumba cyaka gitemba unyuze mu buriri mu kindi cyumba aho materique ceramic ikuramo ubushyuhe bwa gaze, mbere yo gusohoka mu kirundo.Ubushyuhe bwakuwe muburiri mucyumba cyo gusohoka noneho bukoreshwa mugushushanya umwuka winjira mugihe gikurikiraho.
Impuzandengo yigihe cyizuba iratandukanye kuva amasegonda 60 kugeza 120 bitewe na kamere hamwe nubunini bwanduye.Icyumba cya gatatu cyemerera gukomeza gutunganya imyanda ihumanya ikirere, ibyo guhinduranya bitabujije kuguma mu cyumba cyaka ku bushyuhe bukenewe mu gihe gikenewe.Kugirango wirinde gushyuha hejuru ya okiside yumuriro mugihe habaye ubukana bwinshi bwa solvent, hakoreshwa bypass ishyushye itemba ishyushye biturutse kumuriro.Uyu mugezi uri kuri 900 ° C urashobora gukoreshwa nkurugero rwo gushyushya amavuta yumuriro, amazi cyangwa kubyara amavuta.
