Kuwongolera Kutentha Kwambiri kwa Laser Systems ndi Industrial Applications Kuyambira 2002
Chilankhulo
Laser chillers amagwira ntchito yofunika kwambiri pakuwongolera kachulukidwe ka sintering ndikuchepetsa mizere yosanjikiza muzitsulo zosindikizira za 3D pokhazikitsa kutentha, kuchepetsa kupsinjika kwa kutentha, komanso kuonetsetsa kuti ufa wofanana uphatikizidwe. Kuziziritsa koyenera kumathandiza kupewa zolakwika monga pores ndi mpira, zomwe zimapangitsa kusindikiza kwapamwamba komanso zigawo zachitsulo zolimba.
Ndi kukula kwa makina osindikizira azitsulo a 3D pakupanga mafakitale, kufunikira kwa zida zosindikizidwa zapamwamba kwakula. Zina mwazinthu zomwe zimakhudzidwa kwambiri ndi mizere yowoneka bwino komanso kuchepetsedwa kwa sintering. Izi sizimangokhudza kukongola kwapamwamba komanso kuwonetsa zolakwika zamkati monga pores kapena kusakanizika kosakwanira pakati pa zigawo, zomwe zimasokoneza kukhulupirika kwa makina.
Chifukwa Chake Kwambiri Layer Lines Lower Sintering Density
Mizere yayikulu yosanjikiza nthawi zambiri imawonetsa kusalumikizana bwino kwa interlayer kapena ma microvoid pakati pa zigawo za ufa. Pa laser sintering, ufa wachitsulo uyenera kusungunuka ndi kulimba mofanana kuti ukhale wandiweyani, wopanda chilema. Ngati zinthu zosungunula sizingathe kudzaza mipata pakati pa tinthu tating'onoting'ono, porosity yamkati imawonjezeka, kuchepetsa kachulukidwe ka sintering mwachindunji. Kuonjezera apo, kuthamanga kwachangu kusindikiza kapena kutentha kosasunthika kungayambitse kutenthedwa kwakukulu kwa kutentha kapena makina, zomwe zimayambitsa kusungunuka kosafanana, kusuntha kwa tinthu, ndi kugwirizanitsa kofooka, zonse zomwe zimapangitsa kuti pakhale kusanjika kowoneka ndi kusokonezeka kwa gawo.
Momwe Ma Laser Chiller Amakulitsira Kachulukidwe ka Sintering
Ma laser chiller amatenga gawo lofunikira pakukhazikitsa malo otentha a osindikiza azitsulo a 3D. Mwachitsanzo, TEYU CWFL-3000 fiber laser chiller imakhala ndi zigawo ziwiri zowongolera kutentha, imodzi ya fiber laser source ndi inayo ya optics. Kuziziritsa koyenera kumeneku kumapangitsa kuti chipindacho chizizizira bwino, zomwe zimapangitsa kuti ufa wachitsulo usungunuke ndi kulimba mofanana, motero kumawonjezera kachulukidwe ka sintering.
Pozungulira madzi ozizira, ma laser chiller amachotsa kutentha kwakukulu kuchokera kuzinthu zazikulu monga mutu wosindikizira ndi gawo lapansi lachitsulo. Izi zimachepetsa kupsinjika kwamatenthedwe, zomwe zimathandiza kupewa kusamuka kwa ufa ndi kumenyana. Kuphatikiza apo, kuziziritsa koyendetsedwa kumathandizira kutentha koyenera kuzungulira dziwe losungunuka, kulimbikitsa kulimba kolimba ndikuchepetsa mapangidwe a pore.
Laser chillers amathandizanso kupondereza zotsatira za balling, chodabwitsa chomwe ufa wosakwanira wosungunuka umapanga tinthu tating'onoting'ono tozungulira m'malo molumikizana ndi wosanjikiza. Poyang'anira kutentha kozungulira ndi kuzizira, zozizira zimalimbikitsa kuphatikizika kwazitsulo, kuchepetsa vutoli ndikuwonjezera kachulukidwe komaliza.
Kuchepetsa Layer Lines ndi Laser Chillers
Malo okhazikika otentha ndikofunikira kuti muchepetse mizere yosanjikiza muzosindikiza zazitsulo za 3D. Ma laser chiller amathandizira kutentha kofanana m'chipinda chonse chosindikizira, kupewa kutenthedwa kwapadziko lonse komanso kusungunuka kosafanana. Izi zimabweretsa masinthidwe osalala, zolakwika zochepa, komanso kulondola kwa mawonekedwe. Mwachidule, kasamalidwe koyenera ka kutentha sikumangowonjezera kukongola kwa mbali komanso kumatsimikizira kukhulupirika kwazitsulo zosindikizidwa za 3D.
Tabwera chifukwa cha inu mukadzatifuna.
Chonde lembani fomu yolumikizana nafe, ndipo tidzakhala okondwa kukuthandizani.

TEYU S&A Chiller idakhazikitsidwa mu 2002 ndi zaka 23 zopanga zoziziritsa kukhosi, ndipo tsopano amadziwika kuti ndi mpainiya waukadaulo wozizira komanso mnzake wodalirika pamakampani a laser.
