Into ebalulekileyo ekusebenzeni kakuhle kwesithando sokutshiza i-vacuum kukusetyenziswa kwegesi kunye namandla ngendlela engabizi kakhulu. Ngokweentlobo ezahlukeneyo zegesi, ezi zinto zimbini zeendleko zenkqubo yokutshiza zinokuthatha i-50% yeendleko zizonke. Ukuze kongiwe ukusetyenziswa kwegesi, kufuneka kusetyenziswe indlela yoxinzelelo oluncinci lokuhamba kwegesi oluhlengahlengiswayo ukuqinisekisa ukuba iinkqubo zokususa amafutha kunye nokutshiza azinangcoliseko. Ukuze kuncitshiswe ukusetyenziswa kwamandla, izinto zokufudumeza ezilungiselelweyo zisetyenziselwa ukwenza iindawo ezishushu ukunciphisa ukulahleka kobushushu. Ukuze kufezekiswe la manqaku oyilo kunye nokulawula iindleko ze-R & D ngaphakathi koluhlu olufanelekileyo, isithando sokutshiza i-vacuum sanamhlanje esonga izixhobo siya kusebenzisa izixhobo zokubala ze-hydrodynamic ukufumana indlela efanelekileyo yokuhamba komoya kunye nendlela efanelekileyo yokuhamba kobushushu.
Ukusetyenziswa kweentlobo ezahlukeneyo zesithando somlilo
Nokuba yeyiphi na inkqubo eyenzelwe wena nekhethekileyo, uninzi lwee-sintering furnaces ezikwimarike zinokwahlulwa zibe yi-vacuum furnace eyenzeka rhoqo kunye ne-continuous atmosphere furnace. Iinxalenye ezimdaka emva kokubumba ngenaliti kunye ne-catalytic / degreasing ziqulethe i-residual polymer. Zombini ezi ntlobo ze-furnace zibonelela ngesicwangciso sokususa i-polymer ngobushushu.
Kwelinye icala, kufanelekile ngakumbi ukusebenzisa ngokupheleleyo i-continuous atmosphere furnace ukuba yinxalenye enkulu enemveliso yobuninzi ehambelanayo okanye imo efanayo. Kule meko, ngomjikelo omfutshane kunye nomthamo ophezulu wokusila, ixabiso elifanelekileyo leendleko kunye neenzuzo lingafumaneka. Nangona kunjalo, kwimigca yemveliso emincinci nephakathi, le continuous atmosphere furnace enomphumo omncinci wonyaka we-150-200t, iindleko eziphezulu zokufaka kunye nomthamo omkhulu azibizi kakhulu. Ngaphezu koko, i-continuous atmosphere furnace idinga ixesha elide lokuvala ekugcinweni, nto leyo enciphisa ukuguquguquka kwemveliso.
Kwelinye icala, isithando somlilo esisetyenziswa rhoqo nge-vacuum sintering sinobuchwepheshe obubalaseleyo bokulawula inkqubo yokususa amafutha. Imida ekhankanyiweyo ngaphambili, kuquka ukuguqulwa kwejometri kunye nokubola kweekhemikhali kwiindawo ze-MIM, ingasonjululwa ngempumelelo. Esinye isisombululo kukuhlamba izinto ezibophayo ngegesi yenkqubo ye-laminar ngenkqubo yolawulo lwegesi echanekileyo. Ukongeza, ngokunciphisa umthamo wendawo eshushu, ukulingana kobushushu besithando somlilo esisetyenziswa rhoqo kulungile kakhulu, ukuya kuthi ga kwi-LK. Ngokubanzi, isithando somlilo esisetyenziswa rhoqo sinomoya ococekileyo, iiparameter zenkqubo ezihlengahlengiswayo zesithando somlilo esisetyenziswa rhoqo kunye nokungcangcazela kwenxalenye encinci, okwenza kube lukhetho lobuchwephesha lokuvelisa iindawo ezikumgangatho ophezulu (ezifana nezixhobo zonyango). Iinkampani ezininzi zijongene nemiyalelo eguquguqukayo kwaye kufuneka zenze iindawo ezineemilo kunye nezixhobo ezahlukeneyo. Ukungena okuphantsi kunye nokuguquguquka okuphezulu kwesithando somlilo esisetyenziswa rhoqo kuya kudala iimeko ezilungileyo kuzo. Ukuqhuba iqela lezithando zomlilo ezisetyenziswa rhoqo akunakubonelela kuphela ngemigca yemveliso engaphezulu, kodwa kukwaqhuba neenkqubo ezahlukeneyo zenkqubo ngaxeshanye.
Nangona kunjalo, ezinye izitofu zokucoca nge-vacuum ezingobuchwephesha ezineenzuzo zobugcisa ezingentla zithintelwe bubungakanani obuncinci obufumanekayo. Ukungalungi kwazo kumlinganiselo wokufaka-imveliso kunye nokusetyenziswa kwamandla aphantsi kwenza iindleko zokucoca zeendawo zilingane neendleko ezigciniweyo kwezinye izixhobo ze-MIM.
