Vim li cas sandblasting ncua lub neej molybdenum phaj hauv lub tshuab nqus tsev vacuum?

Lub melting point ntawm molybdenum yog siab li 2620 degree, thiab nws muaj ib tug muaj zog kub kub kuj, tab sis nyob rau hauv cov kev siv ntawm cov tswv yim kev lag luam kev siv, ntshiab siab purity yog deb ntawm txaus. Cov cua sov tiv thaiv txheej, lub qhov cub hluav taws xob txhawb nqa, thermal hluav taws xob phaj, thiab lwm yam khoom siv hauv lub tshuab nqus tsev vacuum tsis tsuas yog yuav tsum tau tiv thaiv lub voj voog kub ntawm ntau txhiab degrees, tab sis kuj ntsib teeb meem xws li cua sov, txheej adhesion, thiab oxide tiam.

Lub ntsiab ntawm kev kho sandblasting yog tsim kom muaj ib qho kev ntxhib los mos microscopic ntxhib ntxhib ntxhib los mos ntawm qhov chaw ntawm molybdenum phaj los ntawm kev tswj cov abrasive thiab siab (Ra qhov tseem ceeb feem ntau yog nyob nruab nrab ntawm 3.2-6.3 µ m, uas tuaj yeem ua raws li qhov xav tau). Qhov zoo li yooj yim roughening txheej txheem no tau coj txog ntau yam kev hloov pauv tseem ceeb:

Ua ntej ntawm tag nrho cov, nws zoo tshem tawm cov seem oxide txheej, roj stains, thiab me me impurities nyob rau hauv cov txheej txheem ntawm molybdenum daim hlau, ua rau saum npoo "huv thiab toothed". Qhov thib ob, qhov kev ntxhib los mos zoo heev ua rau thaj chaw tiag tiag, muab cov khoom siv dag zog muaj zog rau cov thermal txau tom ntej, ceramic txheej, lossis cov ntaub ntawv thermal rwb thaiv tsev. Ntau qhov xwm txheej hauv kev lag luam tau pom tias cov txheej txheej ntawm cov khoom siv hluav taws xob sab hauv siv cov xuab zeb blasted molybdenum daim hlau tuaj yeem tshaj 50%, thiab lub voj voog tu ncua ntev.

Kuv tau txais kev tawm tswv yim los ntawm qee lub tshuab nqus tsev vacuum manufacturers: Nyob rau hauv thaum ntxov hnub, lawv siv ci molybdenum daim hlau ua cua sov shields. Qhov saum npoo du yog qhov zoo- saib, tab sis nws yooj yim rau swb thaum ntsia thiab kho, thiab qhov adhesion tsis txaus tom qab txheej txheej nrog siab - kub resistant coatings. Hauv zos peeling pib tshwm sim, ua rau txo qis hauv thermal efficiency thiab qhov kub tsis sib xws.

Tom qab siv sandblasting ntawm molybdenum phaj, cov teeb meem no tau pom tseeb zoo dua. Qhov ntxhib saum npoo tsis tsuas yog txhim kho cov txheej txheej adhesion tab sis kuj txhim kho lub teeb pom kev ntawm cov wavelengths tshwj xeeb rau qee qhov, pab kom ua tiav qhov ntsuas kub zoo dua hauv qee qhov kev kho cua sov. Nyob rau tib lub sijhawm, sandblasting kuj tuaj yeem txo qhov cuam tshuam ntawm molybdenum recrystallization thiab embrittlement ntawm tag nrho cov qauv ntawm qhov kub thiab txias rau qee qhov, vim tias cov nplaum zoo dua tuaj yeem sib koom ua ke ntawm kev ntxhov siab.

Ntawm chav kawm, sandblasted nto tsis yog ib tug panacea. Hauv ob peb lub sijhawm uas yuav tsum tau ua haujlwm kho qhov muag tsis zoo lossis ultra- qis, qhov ci polished nto tseem muaj qhov zoo. Txawm li cas los xij, nyob rau hauv daim ntawv thov ntawm feem ntau siab - qhov kub thiab txias cov txheej txheem thiab txheej substrates, kev ua tau zoo ntawm sandblasting molybdenum daim hlau yog ntau pragmatic.

Raws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tshiab, thiab lwm yam kev lag luam muaj ntau dua thiab siab dua rau kev kho cua sov, cov neeg siv tsis tuaj yeem "tuaj yeem tiv taus qhov kub siab" ntawm molybdenum daim hlau, tab sis nrhiav kev siv cov nqi qis dua thiab cov txheej txheem ruaj khov dua, rov ua dua. Kev kho sandblasting nto tsuas yog ua tau raws li qhov kev thov no- nws cov nqi kuj tseem tswj tau, cov txheej txheem yog cov paub tab, thiab cov txheej txheem saum npoo tuaj yeem tswj tau ntau zaus. Nws yog qhov kev xaiv zoo tshaj plaws ntawm ntau lub siab - kawg lub tshuab nqus tsev vacuum thiab siab - cov khoom siv kub kub.

Ntxiv nrog rau kev tswj xyuas nruj me ntsis ntawm purity thiab thickness tolerances ntawm lub substrate, peb kuj them tshwj xeeb mloog mus rau lub nto uniformity thiab batch sib xws ntawm sandblasting nto molybdenum daim hlau peb muab. Ntau tus neeg siv khoom qub tau tshaj tawm tias qhov kev xav zoo tshaj plaws tom qab siv nws yog "txhawj-dawb": nws ruaj khov rau nruab, muaj teeb meem tsawg dua thaum lub sijhawm ua haujlwm, thiab yooj yim los tswj tom qab.

Yog tias koj xaiv cov khoom siv rau lub tshuab nqus tsev vacuum transformation, semiconductor siv lead ua kev loj hlob rauv, lossis cov khoom siv kub kub sintering, nws raug nquahu kom tsom mus rau kev daws ntawm sandblasting nto. Qhov sib txawv Ra qhov sib txawv raws li qhov yuav tsum tau ua ntawm adhesion sib txawv, thiab peb tuaj yeem pom zoo rau qhov sib txawv ntawm qhov tsis sib xws thiab cov phaj tshwj xeeb raws li koj qhov kev ua haujlwm tshwj xeeb.

Kev ntseeg siab ntawm cov khoom siv siab- kawg feem ntau yog muab zais rau hauv kev kho qhov chaw txo qis. Ib lub phaj sandblasting molybdenum zoo tuaj yeem ua rau tag nrho cov khoom siv khiav mus rau ob peb xyoos ntxiv thiab nres ob peb zaug hauv qhov hnyav. Qhov no tsis yog tsuas yog kev xaiv ntawm cov ntaub ntawv, tab sis kuj yog qhov guarantee ntawm cov txheej txheem stability.

Xav tau peb los muab cov lus qhia kev tsis sib xws ntawm cov khoom siv sandblasting molybdenum phaj, cov ntaub ntawv siv tau, lossis cov lus qhia xaiv rau koj cov khoom siv? Kev sib txuas lus yeej ib txwm txais tos.
