Njengoko sisazi, ulawulo lobushushu isitshixo esiyimfuneko yonke processing thermal, izinto differnet kufuna unyango ezahlukeneyo, kunye nezinto ezifanayo kunye noxinaniso ezahlukeneyo, nazo kufuneka ukuguqulwa uhlengahlengiso lobushushu.Ubushushu ayisositshixo esibalulekileyo kuphela kwiinkqubo zobushushu, kubaluleke kakhulu kwishishini leMIM kuba lichaphazela ngokuthe ngqo ukusebenza kokugqibela kweemveliso nokuba ziyahambelana nemfuneko okanye hayi.Ke indlela yokuqinisekisa ukuba ubushushu bunokulawulwa kakuhle ngexesha lemveliso, ngulo mbuzo, i-KELU ithathele ingqalelo ukuyixoxa ngemiba emibini.
Okokuqala, kukufana ngaphakathi kwiziko lomlilo ngelixa i-sintering, ibaluleke kakhulu ekubumbeni inaliti yentsimbi (MIM).Umgangatho wemveliso kule nkqubo, uxhomekeke kumalungu acutshungulwayo abona ubushushu obufanayo nokuba bukwindawoni na eziko.Njengoko iziko liba likhulu, kuba nzima ngakumbi ukwazi kunye nokuchaza indawo emnandi ngaphakathi kwesithando somlilo kuba xa i-thermocouple ifunda ubushushu obuthile, oko akuthethi ukuba zonke iziko likulo bushushu.Oku kuyinyani ngokukodwa kwisithando somlilo sebhetshi enkulu kunye nomthwalo opheleleyo xa kukho i-gradient enkulu yokushisa phakathi kwangaphandle komthwalo kunye neziko lomthwalo.
Izibophelelo kwicandelo le-MIM ziyasuswa ngokubamba kumaqondo obushushu athile kangangexesha elithile.Ukuba iqondo lokushisa elichanekileyo alifezekiswanga kuwo wonke umthwalo, iprofayili ingadlulela kwicandelo elilandelayo, elidla ngokuba yi-ramp.Izibophelelo ziya kuba zivela ngaphandle kwenxalenye ngexesha lerempu.Ngokuxhomekeke kwisixa se-binder eseleyo kwinxalenye kunye nobushushu ngexesha le-ramp, ukukhuphuka ngokukhawuleza kwe-binder kunokubangela ukuqhekeka okungamkelekanga okanye ama-blisters.Kwezinye iimeko, ukubunjwa kwe-soot kwenzeka, okunokubangela ukuba ukubunjwa kwezinto kutshintshe.
Ngaphezu koko singakwazi ukulawula ubushushu ngeNozzle kunye neBarrel ukusuka kwinkqubo yokubumba inaliti.Ubushushu bombhobho budla ngokuba ngaphantsi kancinane kunobona bushushu bobukhulu bomphanda, oko kukuthintela isenzeko sokuphuma kwamathe esinokuthi senzeke kumbhobho.Ubushushu bombhobho akufanele bube sezantsi kakhulu, ngaphandle koko umlomo uya kuvaleka ngenxa yokunyibilika kokuqina kwangaphambili.Kuya kuba nefuthe ekusebenzeni kwemveliso.Ubushushu bomgqomo.Ubushushu bombhobho, umbhobho kunye nokungunda kufuneka kulawulwe ngexesha lokubumba inaliti.Amaqondo okushisa amabini okuqala achaphazela kakhulu iplastiki yensimbi kunye nomsebenzi, kwaye owokugqibela uchaphazela kakhulu umsebenzi wesinyithi kunye nokupholisa.Isinyithi ngasinye sinobushushu obuhlukeneyo obusebenzayo.Nkqu intsimbi efanayo iye ezahlukeneyo ubushushu esebenzayo kunye zokwenziwa ngenxa imvelaphi eyahlukileyo okanye uphawu.Oko kubangelwa yi-avareji eyahlukeneyo yokusabalalisa ubunzima bemolekyuli.Inkqubo yokwenza iplastiki yesinyithi kwiimatshini ezahlukeneyo zokutofa nayo yahlukile, ukuze ubushushu bombhobho buhluke.
Akukhathaliseki ukuba luhlobo luni lokungakhathali kweyiphi inkqubo encinci, ukusilela akunakuphepheka.Ngethamsanqa iqela lobunjineli be-KELU linamava kunye nobuchule obugqwesileyo ngaphezu kweminyaka elishumi, yenza ukuba abathengi bethu bangabinaxhala malunga nomgangatho weemveliso.Wamkelekile ukuxoxa neqela lethu ukuba kukho nayiphi na imibuzo okanye naluphi na uyilo lwesiko, iqela lethu liya kunceda ukufezekisa iphupha lakho.
