1. Isitoreji
Imikhiqizo ye-Tungsten ne-molybdenum kulula ukuyikhipha i-oxidize futhi iguqule umbala, ngakho kufanele igcinwe endaweni enomswakama ongaphansi kuka-60%, izinga lokushisa elingaphansi kuka-28°C, futhi ihlukaniswe namanye amakhemikhali.
Ama-oxide emikhiqizo ye-tungsten ne-molybdenum ayancibilika emanzini futhi ane-asidi, sicela unake!
2. Ukungcoliswa kwemvelo
(1) Emazingeni okushisa aphezulu (eduze nendawo yokuncibilika kwensimbi), izosabela nezinye izinsimbi (i-iron nama-alloys ayo, i-nickel nama-alloys ayo, njll.), ngezinye izikhathi kubangele i-embrittlement yezinto.Lapho wenza ukwelashwa okushisa kwemikhiqizo ye-tungsten ne-molybdenum, ukunakwa kufanele kukhokhwe!
Ukwelashwa kokushisa kufanele kwenziwe ku-vacuum (ngezansi kwe-10-3Pa), ukunciphisa (H2) noma i-inert gas (N2, Ar, njll.) emkhathini.
(2) Imikhiqizo ye-Tungsten ne-molybdenum izofiphala lapho isabela ngekhabhoni, ngakho ungayithinti lapho ukwelashwa kokushisa kwenziwa ezingeni lokushisa elingaphezu kuka-800°C.Kodwa imikhiqizo ye-molybdenum engaphansi kuka-1500 ℃, izinga le-embrittlement elibangelwa i-carbonization lincane kakhulu.
3. Ukwenza imishini
(1) Ukugoba, ukubhoboza, ukugunda, ukusika, njll. imikhiqizo yamapuleti e-tungsten-molybdenum ijwayele ukuqhekeka lapho icutshungulwa ezingeni lokushisa elilingana negumbi, futhi kufanele ishiswe.Ngesikhathi esifanayo, ngenxa yokucubungula okungalungile, ngezinye izikhathi i-delamination iyenzeka, ngakho-ke ukucubungula ukushisa kuyanconywa.
(2) Nokho, ipuleti le-molybdenum lizoba brittle lapho lishisisa ngaphezu kuka-1000°C, okuzodala ubunzima ekucubunguleni, ngakho kufanele kuqashelwe.
(3) Lapho ugaya ngomshini imikhiqizo ye-tungsten ne-molybdenum, kuyadingeka ukukhetha indlela yokugaya efanele izikhathi ezihlukahlukene.
4. Indlela yokususa i-oksijeni
(1) Imikhiqizo ye-Tungsten ne-molybdenum kulula ukuyikhipha i-oxidize.Lapho ama-oxide asindayo edinga ukususwa, sicela uphathise inkampani yethu noma welaphe nge-asidi eqinile (i-hydrofluoric acid, i-nitric acid, i-hydrochloric acid, njll.), sicela unake lapho usebenza.
(2) Ukuze uthole ama-oxide aphakathi nendawo, sebenzisa into yokuhlanza ngezinsimbi, sula ngendwangu ethambile noma isipontshi, bese ugeza ngamanzi afudumele.
(3) Sicela uqaphele ukuthi i-metallic luster izolahleka ngemva kokugeza.
5. Izinyathelo zokuphepha zokusetshenziswa
(1) Ishidi le-tungsten-molybdenum libukhali njengommese, futhi izinsimbi ezisemakhoneni nasebusweni bangasemuva zingasika izandla.Uma usebenzisa umkhiqizo, sicela ugqoke izinto zokuzivikela.
(2) Ukuminyana kwe-tungsten cishe kuphindwe izikhathi ezingu-2,5 kunensimbi, kanti ukuminyana kwe-molybdenum cishe kuphindwe izikhathi ezingu-1,3 kunensimbi.Isisindo sangempela sikhulu kakhulu kunokubukeka, ngakho ukuphatha ngesandla kungase kuhlukumeze abantu.Kunconywa ukwenza umsebenzi wezandla lapho isisindo singaphansi kwe-20KG.
6. Izinyathelo zokuqapha ukuphatha
Imikhiqizo ye-tungsten ne-molybdenum yabakhiqizi bamapuleti e-molybdenum yizinsimbi eziphukayo, ezijwayele ukuqhekeka kanye ne-delamination;ngakho-ke, lapho uthutha, qaphela ukuthi ungasebenzisi ukushaqeka nokudlidliza, njengokuwa.Futhi, lapho upakisha, sicela ugcwalise ngezinto ezibamba ukushaqeka.
