Isici sesihlungi senetha lokuhlanza insimbi engagqwali saziwa njengesihlungi sensimbi yokuhluza insimbi engagqwali. Isici sesihlungi senziwe ngezendlalelo ezijwayelekile ezinhlanu sintering net by superposition and vacuum sintering. Isici sesihlungi sesikrini sokuhluza insimbi engagqwali senziwe ngensimbi yokuhlwaya yensimbi engagqwali, ehlukaniswe izingxenye ezinhlanu: ungqimba oluvikelayo, ungqimba lokuhlunga, ungqimba lokusabalalisa, ungqimba lohlaka nohlaka lohlaka. Izinto zokuhlunga zinokunemba okulinganayo nokuzinzile kokuhlunga, amandla aphezulu nokuqina, futhi kuyinto enhle yokuhlunga imicimbi yezikhathi nezidingo eziphakeme zamandla acindezelayo nokunemba kokuhlunga okufanayo.
Umehluko omkhulu phakathi kwensimbi engagqwali sintered mesh filter element nezinye izinto zokuhlunga ukusetshenziswa kwenani elikhulu lenqubo yokushisela ephezulu kakhulu. Isici sesihlungi sintering sensimbi engenasici senziwe nge-sintered filter cartridge ngemuva kokusika nokushisela okuphezulu. Iphuzu elibaluleke kakhulu le-sintering filter cartridge ukusetshenziswa kwenani elikhulu lobuchwepheshe be-welding ephezulu. Igobolondo lesihlungi sintering lishiselwe ngokushisela ngemuva kokugingqika. Ukuzungeza kokuhlangana kwe-welding kufanele kuqinisekiswe. Umthungo wokushisela kufanele ulungiswe ngemuva kokushisela ukwenza ukubukeka konke kube kuhle kakhulu.
Ukukhethwa kwezinto zokusetshenziswa, ukunemba kokulawula kanye nenqubo ye-welding yizinto ezintathu ezibaluleke kakhulu entweni yokuhlunga yensimbi engenasici sintering mesh. Imikhiqizo emakethe ixutshwe ngamehlo enhlanzi, izinto ezisezingeni eliphansi, ukugcwaliswa okuphansi nokunemba kokuhlunga okuphezulu, nobuchwepheshe bokucubungula obubi, okwenza eminye imikhiqizo inikeze ngamanani aphansi kakhulu. Amakhasimende adinga ukupholisha amehlo awo ukugwema ukulahleka okudlula inzuzo nokudala ukulahleka kwezingozi zokukhiqiza.
Umehluko omkhulu phakathi kwento yokuhlunga insimbi engagqwali nezinye izinto zokuhlunga ukusetshenziswa kwenombolo enkulu yenqubo yokushisela ephezulu kakhulu. Insimbi engagqwali sintered anezikhala zensimbi ashiselwe emva kweqa. Ukuzungeza kokushisela kufanele kuqinisekiswe futhi i-weld kufanele ilinganiswe ngemuva kokushisela, ukuze yonke ibukeke ibe yinhle futhi ilungiselele ukusheleka okulandelayo okulandelayo.
Ngemuva kwalokho, i-mesh sintering is ashiselwe ekugcineni ehlanganisa kuzo zombili iziphetho ngocingo lwensimbi olungagqwali. Ngesikhathi senqubo yokushisela, i-mesh sintering ayikwazi ukushiswa ukuvimbela ukushiswa kwendawo nokuwohloka, okuholela ekutheni into yokuhlunga yehluleke ukudlala indima yokuhlunga. Ngakho-ke, ukuvikelwa kwegesi ye-argon kufanele kwenziwe endaweni yokushisela ngesikhathi senqubo yokushisela. Yonke le nqubo yokushisela ngenhla kumele ibe nethuluzi lokushisela kanye nemishini ekhethekile yokuwelda, futhi izidingo zobuchwepheshe be-welding zabasebenzi nazo ziqinile. Uma kwenzeka ukuvuza komoya ebangeni lengcindezi ngemuva kokuhlolwa kwe-welding bubble, zonke izinto zokuhlunga zizosuswa.
