Nws cov ntsev-txhaj tshuaj thiab UV tiv thaiv tuaj yeem txhim kho ntxiv nrog anodizing lossis nano-ceramic coatings rau kev txhim kho durability thiab zoo nkauj.
Coastal Bridges:Siv nyob rau hauv tsis yog -load- cov kabmob txuas txuas txuas, 5083 txhuas txo cov nqi txij nkawm ntau dua 50% thaum muab kev ua kom zoo nkauj.
Marine Protective Structures:Ua haujlwm nyob rau hauv cov dej tawg, rov qab, thiab seawalls, 5083 txhuas phaj tiv thaiv nthwv dej cuam tshuam thiab dej hiav txwv corrosion, zoo tiv thaiv cov ntug dej hiav txwv.
Kev xaiv thiab ua cov lus pom zoo
Kev xaiv kub:
H116/H321:Pom zoo rau cov qauv hull; stabilized los tswj -theem nag lossis daus ntawm cov ciam teb rau kev tiv thaiv corrosion zoo dua.
H112:General - lub hom phiaj marine structures, muab kev ua haujlwm sib luag ntawm tus nqi qis.
Cov ntawv sau ua haujlwm:
Vuam:Nyiam 5356 vuam hlau; tswj cov khoom siv hluav taws xob tiv thaiv kom tsis txhob muaj qhov muag muag hauv tshav kub- thaj tsam cuam tshuam.
Cold forming:Sib sib zog nqus- cov khoom kos yuav tsum ruaj khov ntawm 290℃rau 2 teev los tiv thaiv lub caij nplooj ntoos hlav-rov qab (0.1–0.3 mm) vim muaj kev laus.
Kev kho deg:Hard anodizing tuaj yeem ua tiav 25 μm thickness (300 HV), txuas lub neej kev pabcuam hauv marine cua mus txog 15 xyoo.
