C44300 Admiralty tooj dagyog inhibited nrog arsenic los tiv thaivdezincification nyob rau hauv cov kuab paug, stagnant, los yog sulfide -cov dej bearing. Nws ua tau zoo hauv cov roj refinery condensers qhov dej tsis zoo.C68700 Aluminium Brassyog alloyed nrog aluminium los tiv thaivimpingement yaignyob rau hauv siab - ceev ceev huv seawater. Kev xaiv nyob ntawm seb qhov kev hem thawj tseem ceeb yog tshuaj tua kab mob (C44300) lossis kev puas tsuaj (C68700).
4. C44300 vs C70600: Qhov twg zoo dua rau cov dej qias neeg?
C44300 Admiralty tooj dagfeem ntau nyiam raupolluted, sulfide- muaj cov dej tsis huvvim nws cov arsenic inhibitor nquag tiv thaiv dezincification.C70600 CuNi (90/10)muaj kev tiv thaiv corrosion ntau dua tab sis ntawm tus nqi siab dua. Rau refinery overhead condensers tuav cov dej tsis huv, C44300 muab tus nqi zoo tshaj -kev ua haujlwm sib npaug.
5. Vim li cas C44300 tiv thaiv dezincification thaum tus qauv tooj dag tsis ua haujlwm?
Tus qauv tooj dag (xws li, C28000) poob zinc nyiam nyob rau hauv kev pabcuam dej, ua ntxeem tau thiab tsis muaj zog.C44300 Admiralty tooj dagmuaj0.02-0.06% Arsenicraws li ib tug inhibitor, uas tsim ib tug tiv thaiv nto zaj duab xis uas blocks zinc leaching. Qhov no yog vim li cas "Inhibited" Admiralty Brass yog qhov yuav tsum tau ua rau kev pabcuam condenser.
