Zinc Aluminium Thermal Spray Txheej rau Marine thiab Offshore Structures
Zinc aluminium thermal spray coatings marine coatings yog siv los tiv thaiv cov txheej txheem steel uas raug rau cov huab cua hauv hiav txwv, tshuaj tsuag ntsev, chloride paug, thiab cov dej hiav txwv. Thaum lub sij hawm thermal spraying, zinc- txhuas hlau yog muab tso rau ntawm steel nto los tsim ib txheej hlau tiv thaiv. Kev xaiv qib, hlau txoj kab uas hla, cov txheej txheem tshuaj tsuag, kev npaj saum npoo, txheej txheej, thiab qhov project specifications yuav tsum raug lees paub raws li cov qauv, khoom siv, thiab kev pabcuam ib puag ncig.
Vim li cas Marine Steel Vulnerable Corrosion?
Marine thiab offshore steel qauv raug cuam tshuam rau cov xwm txheej uas tuaj yeem ua kom corrosion, suav nrog:
Moisture thiab high humidity
Ntsev-laden marine air
chloride- muaj cov deposits
Rov ua dua cov voj voog ntub thiab qhuav
Txau thiab txau raug
Ntug hiav txwv muaj ib puag ncig
Offshore atmospheric tej yam kev mob
Qhov kev pheej hmoo corrosion txawv raws li tus qauv qhov chaw thiab raug. Ib qho kev tiv thaiv tsis tu ncua raug rau cov huab cua hauv hiav txwv yuav muaj qhov sib txawv ntawm cov hlau nyob hauv thaj chaw txaws lossis lwm qhov chaw raug pom.
Vim li no, kev tiv thaiv corrosion yuav tsum raug xaiv raws li qhov chaw pabcuam tiag tiag es tsis yog raws li cov khoom siv npe.
