Magawo awiri olimba atali omanga utoto, osamva bwino madzi a m'nyanja, mankhwala, kuvala ndi kusungunuka kwa cathodic
Mawonekedwe
Kumamatira kwabwino kwambiri & magwiridwe antchito a anti corrosion, kukana bwino kwa cathodic disbandment.
Kukana kwabwino kwa abrasion.
Kukaniza kwambiri kumizidwa m'madzi;kukana mankhwala abwino.
Wabwino makina katundu.
Zovala zolimbana ndi dzimbiri zam'madzi, monga utoto wina uliwonse wa epoxy, mwina choko ndikuzimiririka kwa nthawi yayitali m'mlengalenga.Komabe, chodabwitsa ichi sichimakhudza ntchito ya anti-corrosion.
DFT 1000-1200um ikhoza kufikiridwa ndi wosanjikiza umodzi, sichidzakhudza kumamatira ndi ntchito zotsutsana ndi dzimbiri.Izi zipangitsa kuti njira zogwiritsira ntchito zikhale zosavuta komanso kuwongolera bwino.
Kuti mugwiritse ntchito nthawi zonse, makulidwe a filimu amaperekedwa pakati pa 500-1000 um.
Analimbikitsa ntchito
Kuteteza nyumba zachitsulo m'malo owononga kwambiri, monga madera apansi pamadzi am'mphepete mwa nyanja, zomanga mulu, chitetezo chakunja chamapaipi okwiriridwa, komanso chitetezo chachitsulo m'malo monga akasinja osungira, mafakitale amankhwala, ndi mphero zamapepala.
Kuphatikiza koyenera kosasunthika kungagwiritsidwe ntchito ngati njira yotchingira yosasunthika.
Kupaka kumodzi kumatha kufikira makulidwe owuma a filimu opitilira 1000 ma microns, omwe amathandizira kwambiri njira zogwiritsira ntchito.
Malangizo Ogwiritsira Ntchito
Chithandizo cha substrate ndi pamwamba
Chitsulo:Malo onse ayenera kukhala aukhondo, owuma komanso opanda zowononga.Mafuta ndi girisi ziyenera kuchotsedwa motsatira muyezo wa SSPC-SP1 zosungunulira zosungunulira.
Musanagwiritse ntchito utoto, malo onse amayenera kuunika ndi kusamalidwa malinga ndi muyezo wa ISO 8504:2000.
Chithandizo cha Pamwamba
Sandblasting kuyeretsa pamwamba pa Sa2.5 (ISO 8501-1:2007) mlingo kapena SSPC-SP10, pamwamba roughness 40-70 microns (2-3 mils) tikulimbikitsidwa.Zowonongeka zapamtunda zomwe zimawululidwa ndi mchenga ziyenera kudulidwa, kudzazidwa kapena kuthandizidwa m'njira yoyenera.
Malo oyambira ovomerezeka akuyenera kukhala oyera, owuma, opanda mchere wosungunuka ndi zina zilizonse zapamtunda.Zoyambira zosavomerezeka ziyenera kutsukidwa kotheratu mpaka mulingo wa Sa2.5 (ISO 8501-1:2007) pophulitsa mchenga.
Gwirani mmwamba:Ndi yoyenera kupaka pazitsulo zina zolimba komanso zathunthu zokalamba.Koma kuyezetsa kwakung'ono ndi kuwunika kumafunika musanagwiritse ntchito.
Pamwamba kwina:chonde funsani ZINDN.
Zothandiza ndi Kuchiritsa
● Kutentha kwa malo ozungulira kuyenera kukhala kuchokera ku 5 ℃ mpaka 38 ℃, chinyezi cha mpweya sayenera kupitirira 85%.
● Kutentha kwa gawo lapansi pakagwiritsidwa ntchito ndi kuchiritsa kuyenera kukhala 3 ℃ pamwamba pa mame.
● Kugwiritsa ntchito panja ndikoletsedwa pa nyengo yoopsa monga mvula, chifunga, matalala, mphepo yamphamvu ndi fumbi lamphamvu.Pa kuchiritsa nthawi ngati ❖ kuyanika filimu pansi pa chinyezi mkulu, mchere akhoza kuchitika.
● Kuthirira madzi mkati kapena mukangomaliza kugwiritsa ntchito kumapangitsa kuti pamwamba pakhale mdima komanso wosanjikiza wosanjikiza bwino.
● Kulowa m’madzi osasunthika msanga kungachititse kuti mitundu isinthe.
