Lub xeb hlau pov thawj ntawm cov hlau tsis muaj hlau yog cov yeeb-yaj-kiab los tsim cov yeeb-yaj-kiab oxide kom raug cov pa thiab tiv thaiv kom txhob oxidation ntxiv.


Qhov ua rau 301 Cov Hlau Stainless Steel ncej tau xeb:

1. Hauv chloride muaj ib puag ncig, qhov txhauv yog ceev heev kom nws corrodes ceev dua cov hluav taws kub tsis zoo tib yam. Yog li yuav tsum siv qhov chaw ntawm stainless hlau yuav tsum tau wiped, plua plav tawm, ntxuav thiab qhuav.

2. Cov kev ua xaim hlau tsis tau ua tiav rau hauv daim phiaj siv nyiaj, uas ua rau cov ntsiab lus tsis tshua muaj siab hauv lub koom haum matrix thiab kev tiv thaiv tsis zoo.

3. Cov ntaub ntawv titanium thiab niobium dawb muaj lub siab nyiam ua rau cov hluav taws xob tawg. Ntxiv titanium thiab niobium thiab mam li tso cai ua rau lub cev tsis tuaj yeem ua rau muaj kev sib txheeb ntawm qhov sib qeeb.
