Ukuze ugweme ukupholisa warping ngemuva kwemishini, ngokuvamile, iTungsten Carbide idinga ukushiswa ukushisa, ngemuva kokufudumala, amandla ethuluzi azoncishiswa ngemuva kokuguga, futhi amandla nokuqina kwe-carbide enesihlahla. Ngakho-ke, nge-carbide ekhethwe ngosimende, ukwelashwa okushisa kuyinqubo ebaluleke kakhulu. Namuhla, umhleli weChuangrui uzokhuluma nawe ngolwazi olufanele lokwelashwa okushisa kwe-vacuum.
Ekusebenzeni nasekukhiqizeni ukwelashwa kokushisa kwe-vacuum, kuvame ukuba nezinkinga nge "Umbala" ngaphezulu kwemikhiqizo esetshenzisiwe. Ukuthola umphumela wokuhlola umkhiqizo okhanyayo, ongabonakali umgomo ojwayelekile ophisheke yi-R & D kanye nabasebenzisi be-vacuum Ngakho-ke siyini isizathu sokukhanya? Iziphi izinto ezihilelekile? Ngingawenza kanjani umkhiqizo wami ucwebezele? Le yindaba ekhathazayo kakhulu kochwepheshe bangaphambili ekhiqizweni.
Umbala wombala ubangelwa yi-oxidation, futhi imibala ehlukene ihlobene namazinga okushisa akhiqizwa kanye nobukhulu befilimu ye-oxide. Ukucisha uwoyela ku-1200 ° C kuzokwenza futhi ukunciphisa ukuncibilikisa nokuncibilika kwesendlalelo esingaphezulu, futhi kukhulu kakhulu i-vacuum kuzodala ukuguquguquka kwento kanye nokubopha. Lokhu kungalimaza ukukhanya kobuso.
Ukuze uthole indawo ekhanyayo ekhanyayo, lezi zinyathelo ezilandelayo kufanele zinake futhi zibhekwe ekukhiqizeni ukukhiqiza:
1. Okokuqala, izinkomba zobuchwepheshe zesithando se-vacuum kufanele zihlangabezane namazinga kazwelonke.
2. Ukwelashwa kwenqubo kufanele kube okunengqondo futhi kulungile.
3. Isithando somlilo se-vacuum akufanele singcoliswe.
4. Uma kunesidingo, geza isithando somlilo ngobumsulwa obuphezulu u-inert ngaphambi kokungena nokushiya isithando somlilo.
5. Kufanele kudlule kuhhavini ofanele kusenesikhathi.
Ukukhethwa okungcolile kwe-inert gesi (noma ingxenye ethile yokunciphisa igesi eqinile) ngesikhathi sokupholisa.
Kulula ukuthola indawo ecwebezelayo esithandweni se-vacuum ngoba akulula futhi kubiza kakhulu ukuthola isimo sokuvikela ngephuzu lezodonga le -74 ° C. Kodwa-ke, kulula ukuthola umoya we-vacuum ngephuzu lezodonsi elilingana no -74 ° C nokuqukethwe okufanayo kokungcola okufanayo. Ekusebenzeni nasekukhiqizeni ukwelashwa okushisa kwe-vacuum, insimbi engagqwali, i-titanium alloy, kanye ne-alloy ephezulu kakhulu kunzima. Ukuze uvikele ukuguquguquka kwezinto, ingcindezi (vacuum) yensimbi yethuluzi kufanele ilawulwe ku-70-130pa.
