Cov txheej txheem txheej txheej saum npoo yog qhov tseem ceeb cuam tshuam rau lub cev thiab tshuaj lom neeg ntawm titanium castings. Ua ntej peb grind thiab polish lubluv nqi gr5 titanium phaj, peb yuav tsum tau tshem tawm tag nrho cov txheej txheem deg paug thiaj li ua tiav cov nyhuv polishing txaus. Cov txheej txheem txheej txheej ntawm titanium tuaj yeem raug tshem tawm tag nrho los ntawm cov kua qaub pickling tom qab blasting.
1. Psouting xuab zeb
Dawb corundum feem ntau yog siv rau sandblasting ntawm titanium castings. Lub siab yog qis dua li cov hlau tsis muaj nuj nqis thiab feem ntau tswj tau qis dua 0.45Mpa. Vim hais tias thaum txhaj tshuaj siab dhau lawm, cov xuab zeb hais yuav cuam tshuam rau saum npoo thiab ua kom muaj qhov kub hnyiab. Qhov kub nce tuaj yeem hnov mob nrog titanium nto, tsim cov pa phem thib ob thiab cuam tshuam rau qhov zoo ntawm qhov chaw. Lub sij hawm yog 15 mus rau 30 vib nas this, tsuas yog tshem tawm cov nplaum nplaum, txheej txheej sintering, thiab ib feem thiab oxidation txheej. Qhov seem ntawm cov tshuaj tiv thaiv txheej yuav tsum tau muab tshem tawm sai sai los ntawm kev ntxuav cov kua qaub.
2. Pickling:
Acid pickling tshem tawm cov tshuaj tiv thaiv txheej txheej ntawm lubluv nqi gr5 titanium phajtag thiab sai, tsis muaj kab mob los ntawm lwm yam. HF-HCl system thiab HF-HNO3 series ntawm cov tshuaj pleev ib ce tuaj yeem siv rau titanium, Txawm li cas los xij, hydrogen absorption ntawm HF-HCl system acid yog loj, thaum lub HF-HNO3 me me, yog li cov concentration ntawm HNO3 tuaj yeem tswj tau. txo qhov nqus hydrogen thiab qhov chaw tuaj yeem ci ntsa iab. Qhov dav dav ntawm HF yog li 3% ~ 5% thiab qhov siab ntawm HNO3 yog li 15% ~ 30%.
Thaum kojmuas peb luv nqi gr5 titanium phaj,koj yuav pom tias peb txhim kho cov khoom nto thiab tsim nyog ntawm castings los ntawm kev kho deg.
