"UNC" txhais li cas?

UNC hais txog cov xov ntxhib hauv Tebchaws Meskas cov xov UN series (xaiv sab nraud xov hauv paus radius).

Dab tsi yog Black Oxide nto kho?

Dub oxide, ib qho kev siv tshuaj kho qhov chaw. Dub oxide yog ib txoj hauv kev zoo rau kev kho mob saum npoo av. Lub hauv paus ntsiab lus yog los tsim cov oxide zaj duab xis ntawm cov hlau nto kom cais cov huab cua thiab ua tiav lub hom phiaj ntawm kev tiv thaiv xeb. Thaum cov tsos mob yuav tsum tsis siab, blackening yuav siv tau, thiab nto ntawm steel qhov chaw yog blackened, uas tseem hu ua xiav.

Cov kev siv feem ntau ntawm kev kho mob oxide dub suav nrog cov tsoos alkaline cua sov blackening thiab chav kub blackening uas tshwm sim tom qab. Txawm li cas los xij, cov txheej txheem blackening nyob rau hauv chav tsev kub tsis zoo heev rau cov pa roj carbon tsawg. Alkaline blackening yog subdivided, thiab muaj qhov sib txawv ntawm ib zaug blackening thiab ob zaug blackening. Cov khoom tseem ceeb ntawm blackening kua yog sodium hydroxide thiab sodium nitrite. Qhov sib txawv ntawm qhov kub thiab txias uas yuav tsum tau ua rau blackening tsis loj, thiab qhov chaw zoo tuaj yeem tau ntawm 135-155 ° C, tab sis lub sijhawm yuav tsum tau ntev me ntsis.
