Yuav ua li cas Ulra-dawb huv hlau hloov cov roj carless stainless hlau: 5 science-backed zoo
Cov lus piav qhia meta:Tshawb nrhiav vim li cas 99.98% Cov tawv ntshiab tau hloov kho cov hlau stainless. Los ntawm slashing co₂ kom txhawb nqa alloy yields, kawm cov ntawv zais metts thiab cov khoom noj kom zoo dua li ntsuab.
Cov kev ua si uas ntsiag to nyob rau hauv stainless hlau: Vim li cas cov xim ntshiab purity teeb meem ntau dua li qhov koj xav
Nyob rau hauv ib lub caij nyoog uas tsis muaj roj carless steel tsis yog nyiam tab sis yuav tsum tau ua los ntawm kab kev huab cua dub (99.98% Fe) ntawm cov kab ke tom ntej no meters. Dhau ntawm kev tshawb fawb txog kev ua rau peb pom zoo li cas atomic-theem hlau purity tau unpreck tsis muaj kev ua tau zoo thaum uas tsis muaj kev txhim kho cov hom phiaj.
