Ing corrosion metung ya kareng importanting elementu na magdalangbalbula ning parul sira. Kilubbalbula ning parul proteksyun,balbula ning parul ing proteksyun keng kaagnasan metung yang importanting isyung dapat ikonsidera. Para keng metalbalbula ning paruls, ing surface coating treatment ing pekamasanting a paralan ning proteksyun.
Ing papel ningMetalbalbula ning parul surface coating
01. Pamag-shielding
Kaybat nang mepintura ing metal, ing metal medyu makabukud ya keng kapaligiran. Ing protective effect ayni malyari yang ausan shielding effect. Pero kailangan yang ipabalu na ing manipis a layer ning pintura e ya malyaring maging absolute shielding role. Uling ing matas a polymer atin yang metung a air permeability, nung ing coating manipis ya, ing kayang structural pores paintulutan no reng molecule ning danum ampo oxygen a malayang dumalan. Soft-sealedbalbula ning paruls atin lang mahigpit a requirements keng kapal ning epoxy coating keng babo. akit tamu na para kareng dakal a coatings ing ulaga mas maragul ya kesa keng alang coating a bakal a babo. Para asundu ing impermeability ning coating, ing anti-corrosion coating dapat gumamit yang film-forming substance a maki mababang air permeability ampo metung a solidung filler a maki maragul a shielding property, at kabang panaun, ing bilang da reng coating layers dapat yang dagdagan ban ing coating miras ya king metung a kapal at maging siksik at e porous.
02. Pamagbawal king kaagnasan
King pamakipag-react da reng kilub a sangkap ning coating king metal, ing metal a babo mipapassiv ya o ing metung a proteksiun a sangkap mika-generate ya para asundu ing proteksiun a epektu ning coating.balbula ning parulsgamitan para kareng espesyal a kailangan kailangan yang pansinan ing komposisyun ning pintura para aiwasan ing seryosung e masanting a epektu. Dagdag pa, ing cast steelbalbula ning parul gamitan keng oil pipeline, ing degradation products a gagawan da keng aksyon da reng mapilan a oils ampo ing drying action da reng metal a sabon malyari la namang maglarin bilang organic corrosion inhibitors.
03. Proteksyun keng electrochemical
Ing electrochemical corrosion lalam ning pelikula malilyari ya nung ing dielectric permeable coating makatagkil ya keng metal a babo. Gamitan la reng metal a mas matas a aktibidad kesa keng bakal bilang filler kareng coating, antimo ing zinc. Iti ing magprotekta keng sacrificial anode, ampo ing corrosion products ning zinc ilapin deng basic zinc chloride ampo zinc carbonate, na makapuno keng gap ning membrane ampo gagawang masipit ing membrane, na makabawas keng corrosion ampo makaba keng service life ningbalbula ning parul.
keraklan gagamitan a coatings para keng metalbalbula ning paruls
01.balbula ning parul body epoxy resin coating
Atin yang makatuking katangian:
Lalaban keng kaagnasan
Deng epoxy-coated steel bars atin lang masanting a corrosion resistance, ampo ing bond strength keng concrete maragul yang mabawas. Iti masanting ya para keng industrial a kundisyun keng mabasa a kapaligiran o agresibong media.
masikan a pangadikit
Ing presensya ning polar hydroxyl ampo ether bonds a atyu keng molecular chain da reng epoxy resins gagawan neng matas a adhesive kareng miyayaliwang sangkap. Ing epoxy resin atin yang mababang shrinkage kabang mag-cure ya, at ing internal stress a gagawan na malati ya, at ing protective surface coating e ya madaling mabagsak at mabagsak.
Electrical properties
Ing cured epoxy resin system metung yang masanting a insulating material a maki matas a dielectric properties, surface leakage resistance ampo arc resistance.
Lalaban keng amag
Deng cured epoxy systems lalaban la kareng keraklan a amag at malyari lang gamitan kareng masikan a tropical a kundisyun.
02.balbula ning parul plate nylon plate material
Deng nylon sheets e la makasira at matagumpe lang megamit kareng dakal a aplikasyun antimo ing danum, gabun, pamangan, ampo desalination.
sex keng kilwal
Ing nylon board coating malyari yang mipasa keng salt spray test, at ing coating e ya mebalat kaybat nang milub keng danum ning dagat kilub ning maigit 25 banua, inya alang corrosion kareng metal a bage.
lalaban keng pangagasgas
Atin yang masanting a resistensya keng pangasira.
resistensya keng epektu
Ala yang tanda ning pamagbalat keng masikan a pangabagsak.
