Nta
Zoo heev adhesion & anti corrosion kev ua tau zoo, zoo heev cathodic disbandment kuj.
Zoo heev abrasion tsis kam.
Zoo tshaj dej immersion kuj;zoo tshuaj tiv thaiv.
Zoo heev mechanical zog.
Marine hnyav anti-corrosion coatings, zoo li tag nrho lwm yam epoxy xim, tej zaum chalk thiab ploj mus ntev raug nyob rau hauv lub ambient cua.Txawm li cas los xij, qhov tshwm sim no tsis cuam tshuam rau kev ua haujlwm tiv thaiv corrosion.
DFT 1000-1200um tuaj yeem ncav cuag los ntawm ib txheej, nws yuav tsis cuam tshuam rau adhesion thiab kev ua haujlwm tiv thaiv corrosion.Qhov no yuav ua kom yooj yim cov txheej txheem thov thiab txhim kho kev ua haujlwm.
Rau kev siv dav dav, zaj duab xis thickness pom zoo yog nyob nruab nrab ntawm 500-1000 um.
Pom zoo siv
Txhawm rau tiv thaiv cov txheej txheem steel hauv qhov hnyav hnyav, xws li thaj chaw hauv qab dej ntawm cov qauv sab nrauv, cov txheej txheem pawg, kev tiv thaiv phab ntsa sab nrauv ntawm cov kav dej faus, thiab cov qauv steel tiv thaiv hauv ib puag ncig xws li cov tso tsheb hlau luam, cov nroj tsuag tshuaj, thiab ntawv mills.
Ntxiv qhov tsim nyog tsis-slip aggregate tuaj yeem siv los ua cov txheej txheem tsis-slip.
Ib txheej txheej tuaj yeem ncav cuag cov yeeb yaj kiab qhuav ntawm ntau dua 1000 microns, uas yooj yim rau cov txheej txheem thov.
Cov lus qhia siv
Substrate thiab kho qhov chaw
Hlau:Txhua qhov chaw yuav tsum huv, qhuav thiab tsis muaj kab mob.Roj thiab roj yuav tsum tau muab tshem tawm raws li SSPC-SP1 hnyav tu tus qauv.
Ua ntej siv cov xim, txhua qhov chaw yuav tsum tau soj ntsuam thiab kho raws li ISO 8504: 2000 tus qauv.
Kev kho saum npoo
Sandblasting los ntxuav qhov chaw mus rau Sa2.5 (ISO 8501-1: 2007) qib lossis SSPC-SP10, nto roughness 40-70 microns (2-3 mils) yog pom zoo.Deg qhov tsis xws luag tshwm sim los ntawm sandblasting yuav tsum tau sanded, sau rau hauv los yog kho nyob rau hauv ib tug haum txoj kev.
Qhov pom zoo primer nto yuav tsum huv si, qhuav, thiab tsis muaj soluble ntsev thiab lwm yam kab mob.Cov primers uas tsis tau pom zoo yuav tsum tau muab ntxuav kom tiav rau qib Sa2.5 (ISO 8501-1: 2007) los ntawm sandblasting.
Kov li:Nws yog qhov tsim nyog rau txheej txheej ntawm qee qhov ruaj khov thiab ua tiav cov txheej txheem laus.Tab sis ib cheeb tsam me me thiab kev ntsuam xyuas yuav tsum tau ua ua ntej thov.
Lwm qhov chaw:thov sab laj ZINDN.
Siv tau thiab kho
● Ambient ib puag ncig kub yuav tsum yog los ntawm rho tawm 5 ℃ mus rau 38 ℃, tus txheeb ze cov av noo yuav tsum tsis txhob ntau tshaj 85%.
● Substrate kub thaum lub sij hawm thov thiab kho yuav tsum yog 3 ℃ saum toj dew point.
● Kev thov sab nraum zoov yog txwv tsis pub nyob rau hauv huab cua hnyav xws li nag, pos huab, daus, cua muaj zog thiab plua plav hnyav.Thaum lub sij hawm kho yog tias txheej zaj duab xis nyob rau hauv high humidity, amine ntsev yuav tshwm sim.
● Condensation thaum lub sij hawm los yog tam sim ntawd tom qab daim ntawv thov yuav ua rau dull nto thiab tsis zoo txheej txheej.
● Kev raug dej thaum ntxov tuaj yeem ua rau muaj xim hloov.
