Titanium tube manufacturers tuaj yeem ua kom sov titanium hauv lub tshuab nqus tsev lossis cov pa roj hydrogen kom tshem tawm cov yeeb yaj kiab oxide sab nraud ntawm cov txheej txheem hydrogen nqus. Thaum rhuab mus rau 700-850 degree, cov oxides nyob rau saum npoo ntawm lub titanium raj pib diffuse mus rau cov hlau, thiab cov hydrogen nqus tus nqi ntawm cov kho titanium raj yog loj heev. Txawm li cas los xij, txoj kev no tshem tawm cov pa oxygen hauv oxide zaj duab xis thaum lub sijhawm kho cua sov. Kev nkag mus rau cov hlau tsis yog tsuas yog ua kom qeeb ntawm qhov diffusion ntawm hydrogen rau hauv cov hlau, tab sis kuj tso cai rau cov pa oxygen nkag mus rau cov khoom kawg, yog li txo cov khoom zoo; Nyob rau tib lub sijhawm, cov khoom hauv titanium raj thaum lub sijhawm kho cua sov kuj tuaj yeem ua rau qee qhov kev sintering, txo nws cov hydrogen nqus tus nqi.
Kev tshem tawm roj: Tom qab txias cov hlau billet, siv cov hlau degreaser tshem tawm cov roj stains ntawm qhov chaw ntawm cov kav dej. Thaum noj roj, xyuam xim rau kev taw qhia ntawm lub qhov hauv qhov chaw uas cov roj tau yooj yim khaws cia kom huv si kom tiav. Acid tu: Lub hom phiaj ntawm kev ntxuav cov kua qaub yog tshem tawm cov oxide zaj duab xis tsim tom qab annealing los ntawm titanium raj nto. Nyob rau hauv chav tsev kub, ib tug npaum li cas ntawm cov dej huv tau muab tso rau hauv ib tug acid pickling tank, thiab ib txwm piv ntawm HNO 3 rau HF, HNO 3, thiab HF dej yog HF ntxiv rau seem H2O. Kev hloov kho tau raug ua raws li qhov xwm txheej tiag tiag.
Lub sij hawm pickling yog 10-15 feeb, uas tuaj yeem txiav txim siab raws li qhov xwm txheej pickling. Thaum lub sij hawm pickling txheej txheem, nws yog ib qho tseem ceeb uas yuav tsum nquag tig ib ncig thiab xyuas kom meej tias cov pickling yog uniform thiab tiav, tsis txhob ceev heev los yog ntau pickling. Tom qab pickling, lub titanium raj yog visually soj ntsuam kom tshem tawm cov oxide ntawm daim tawv nqaij nyob rau hauv thiab sab nraum ntawm lub titanium raj, tshem tawm cov nyiaj dawb xim, thiab ntxuav nws.
Tom qab cov kua qaub ntxuav thiab tshuaj xyuas, lub titanium raj yuav tsum tau muab ntxuav kom raws sijhawm kom tshem tawm cov kua qaub thiab cov kua qaub ntxuav cov ntaub ntawv los ntawm sab hauv thiab sab nrauv kom ntseeg tau tias cov ntsiab lus ntawm titanium raj yog ci.
