-196 ℃ tsis tshua muaj kub cuam tshuam, txhua txoj haujlwm txuas ntxiv arc vuam stainless hlau electrode

I. Txheej txheem cej luam
Nrog rau txoj kev loj hlob sai ntawm thoob ntiaj teb tshuaj thiab lub zog logistics, stainless hlau cia tank thiab ntim tau dav siv nyob rau hauv kev thauj mus los thiab cia cov tshuaj, khoom noj khoom haus thiab dej haus, lub zog thiab lwm yam ntaub ntawv.Vim nws zoo heev uas tsis muaj kub toughness thiab zoo corrosion kuj, austenitic stainless hlau yog dav siv nyob rau hauv kev tsim kho ntawm cryogenic cia tso tsheb hlau luam, khoom siv thiab loj cryogenic lug.

3.Our electrode GES-308LT (E308L-16)
Txhawm rau ua kom tau raws li kev xav tau ntawm kev lag luam, peb lub tuam txhab tau tsim ntau yam ntawm qhov kub thiab txias, siab toughness austenitic stainless hlau electrodes, cov tshuaj muaj pes tsawg leeg ntawm cov hlau deposited (raws li qhia nyob rau hauv Table 1) thiab ruaj khov mechanical zog (raws li qhia nyob rau hauv Table 2), thiab muaj cov txheej txheem vuam zoo tag nrho, thiab zoo heev uas tsis muaj qhov kub thiab txias, qhov cuam tshuam ntawm nws cov nyiaj ferrite ntawm qhov cuam tshuam tus nqi (Table 3).
