Nyob rau hauv siab- kawg daim ntawv thov ntawm stainless hlau tubing, tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li hydrogen zog, electronics, pharmaceuticals, thiab semiconductors, uas yuav tsum nruj me ntsis rau cov yeeb nkab nto zoo, huv si, thiab corrosion kuj, BA (Bright Annealed) thiab EP (Electropolished) stainless hlau raj yog ob hom kev siv ntau tshaj plaws ntawm -precision polished tubing. Txawm hais tias ob qho tib si muaj qhov zoo tshaj plaws ntawm qhov tiav, lawv sib txawv hauv lawv cov txheej txheem polishing, tus yam ntxwv saum npoo, qhov zoo ntawm kev ua tau zoo, thiab cov xwm txheej siv tau. Tsab ntawv xov xwm no yuav piav qhia txog qhov sib txawv ntawm BA thiab EP stainless hlau raj thiab, ua ke nrog cov xwm txheej siv tau zoo, muab cov lus qhia meej rau kev xaiv, pab cov kws tshaj lij kev lag luam thiab cov neeg siv khoom thoob ntiaj teb kom haum lawv cov kev xav tau.
BA vs. EP Stainless Hlau Tubes: Txheej txheem sib txawv
1. BA stainless hlau Tubes
Cov txheej txheem tseem ceeb ntawm BA stainless hlau hlab yog "txias dov + ci ntsa iab."

Qhov no yog ib puag ncig tus phooj ywg thiab muaj txiaj ntsig siab - txoj kev polishing precision. Lub hauv paus ntsiab lus yog: lub txias- dov stainless hlau raj yog rhuab mus rau 1050-1100℃nyob rau hauv ib tug tiv thaiv cua thiab maj mam txias kom tsis txhob oxidation. Qhov saum npoo yog dawb ntawm oxide nplai, muaj gloss zoo, thiab qhov roughness yog Ra tsawg dua los yog sib npaug rau 0.4um.
2. EP Stainless Hlau Tubes
Cov txheej txheem tseem ceeb ntawm EP stainless hlau raj yog "txias dov + ci annealing + electropolishing." Siv BA- qib stainless hlau raj raws li cov khoom siv hauv paus, cov raj yog raus rau hauv ib qho electrolyte (xws li phosphoric acid-sulfuric acid sib tov) raws li cov anode, thiab siv tam sim no. Nyob rau hauv qhov kev txiav txim ntawm tam sim no, lub microscopic protrusions nyob rau saum npoo ntawm lub raj yaj nyiam dua, leveling cov hlau nto thiab ib txhij tsim ib ntom, chromium- nplua nuj passivation zaj duab xis. Lub hauv paus ntsiab lus zoo ib yam li "rov qab electroplating," thiab qhov roughness yog Ra tsawg dua los yog sib npaug rau 0.2um.
EP txheej txheem ua rau me ntsis cov khoom poob ntawm lub raj nto (feem ntau Tsawg dua los yog sib npaug rau 0.1mm), yog li yuav tsum tau muaj kev ua haujlwm siab heev hauv kev tsim khoom.
