Inzwa yengcindezi ephezulu yengcindezelo ye-yn52s00027p1 ilungele i-SK200-6 Excaterator of Shengang

Okwezinto ezisetshenziswayo ezisetshenziswa kuma-valves we-Ultra-High Pressure, ukwelashwa kokushisa kanye nokuqina komhlaba kuvame ukusetshenziselwa ukuthuthukisa ukumelana nokuqina kwawo.

1, ukwelashwa okushisa okuvuthayo

Ukwelashwa okushisa kwe-vacuum kusho inqubo yokwelashwa kokushisa lapho umsebenzi we-arkpies ubekwe khona ku-vacuum. Ukwelashwa okushisa kwe-vacuum akukhiqizi i-oxidation, ukuhumusha kanye nokunye ukugqwala ngesikhathi sokufudumeza, kepha futhi kunomsebenzi wokuhlanza ingaphezulu, ukuhlekisa nokuhlehlisa. I-Hydrogen, i-nitrogen no-oxygen bamukelwe yilokho okwenziwa ngokubhema kungasuswa ku-vacuum, futhi ikhwalithi nokusebenza kwezinto ezibonakalayo kungathuthukiswa. Isibonelo, ngemuva kokwelashwa kokushisa kwe-Ultra-high Pressure I-valve eyenziwe nge-W18CRR4V, umthelela ubunyatheli be-valve ye-valve ukhule ngempumelelo, futhi ngasikhathi sinye, izakhiwo zemishini kanye nempilo yenkonzo zithuthukiswa.

2. Ukwelashwa okuqinisayo komhlaba

Ukuze uthuthukise ukusebenza kwezingxenye, ngaphezu kokushintsha okuqukethwe, kutholwa ezinye izindlela zokwelashwa eziqinisa indawo. Njengokuhlanza okungaphezulu (ukufudumeza kwelangabi, indawo eshisa kakhulu nokufudumala okufudumele, xhumana nogesi wokushisa komhlaba okususwayo, i-electrolyte heam surcing, i-carring, i-cyaning, ukuqinisa i-loron (indlela ye-Cherver (PVD Indlela), i-Plasma Chemical Vapor Devise (Indlela ye-PCVD) Ukufafaza kwe-PLASMA, njll.

I-Global Vapor Deposition (Indlela ye-PVD)

Ku-vacuum, izindlela ezibonakalayo ezifana nokuhwamuka, i-ion pliating kanye nokuphamba kusetshenziselwa ukukhiqiza i-inter ion. Lawa ma-Ion wensimbi afakwa ebusweni bendawo yokusebenza ukuze akhe ukuhlanganiswa kwensimbi, noma usabele nge-reactionor ukwakha ikhompiyutha eyinkimbinkimbi. Le nqubo yokwelashwa ibizwa ngokuthi yi-Persic Vapor Deposition, noma i-PVD isikhashana. Le ndlela inezinzuzo zokushisa okuphansi kokushisa, ama-400 ~ 600 ℃ lokushisa lokwelashwa, ukuphuma okuncane kanye nethonya elincane ekwakhekeni kwe-matrix kanye nezindawo zezingxenye. Ungqimba lwe-tin wafakwa kwi-valve yenaliti eyenziwe nge-w18cr4V yi-PVD indlela. Isendlalelo se-tin sinobulukhuni obuphezulu kakhulu (2500 ~ 3000hv) kanye nokumelana okuphezulu, okuthuthukisa ukumelana nokugqwala kwe-valve, akulonakaliswa nge-dilute hydrochloric acid, sulfuric acid ne-nitric acid, futhi kungagcina indawo ekhanyayo. Ngemuva kokwelashwa kwe-PVD, ukunamathela kunokunemba okuhle. Kungaba yinhlabathi futhi kuphangwe, futhi ubuqili bawo bungaphezulu yiRa0.8μm, elingafika ku-0.01μm ngemuva kokupholisha.
