Awiri chigawo epoxy wapakatikati utoto polyamide adduct ochiritsidwa, chotchinga chabwino ndi anticorrosion katundu, kugonjetsedwa ndi madzi, mafuta, mankhwala, yaitali recoating katundu.
Mawonekedwe
Chifukwa cha kuchuluka kwa flaky mica iron oxide yomwe imaphatikizidwa, imapanga "labyrinth" mufilimu ya utoto, kotero filimu ya utoto imakhala ndi chotchinga chabwino kwambiri komanso kukana dzimbiri.
Kukana kwabwino kwa mlengalenga wamankhwala, mlengalenga wa mafakitale ndi mlengalenga wam'madzi, komanso kukana madzi a m'nyanja, mchere, asidi ofooka ndi alkali ofooka.Nthawi yayitali yobwezeretsanso.
Analimbikitsa ntchito
1.Kugwiritsidwa ntchito ngati gawo lapakati ndi kusindikiza kusindikiza kwa utoto wotsutsa dzimbiri monga epoxy zinc-rich primer ndi inorganic zinc-rich primer kuti apititse patsogolo zotchinga ndi zotetezera za zokutira zonse.
2.Kugwiritsidwa ntchito ngati antirust primer kwa nyumba zachitsulo.
3.Used ngati interlayer mu ❖ kuyanika dongosolo chitetezo konkire.
4.Kugwiritsidwa ntchito ngati topcoat yokonza pamwamba pa zokutira zakale komwe kuvomereza kumalola.
Malangizo Ogwiritsira Ntchito
Chitsulo:kuphulika kutsukidwa kwa Sa2.5 (ISO8501-1) kapena osachepera SSPC SP-6, kuphulika mbiri Rz30μm~75μm (ISO8503-1) kapena chida mphamvu kutsukidwa kuti osachepera ISO-St3.0/SSPC SP3
Zoyambira zophimbidwa kale za workshop:Ma welds, ma calibration zozimitsa moto ndi kuwonongeka ziyenera kuphulika kutsukidwa mpaka Sa2.5 (ISO8501-1), kapena chida champhamvu chotsukidwa mpaka St3.0.
Pamwamba ndi primer yokutidwa:Kuyeretsa ndi kuuma popanda mchere wa zinc ndi dothi.
Gwirani mmwamba:Chotsani mafutawo pamwamba ndikuchotsa mchere ndi litsiro lina.Ndi bwino kugwiritsa ntchito kuyeretsa kuphulika kuchotsa dzimbiri ndi zinthu zina zotayirira.Gwiritsani ntchito chida champhamvu kuti mupukutire malo a dzimbiri, ndikuyalanso zinthu izi.
Zothandiza ndi Kuchiritsa
1.Ambient kutentha kwa chilengedwe kuyenera kukhala kuchokera ku 5 ℃ mpaka 35 ℃, chinyezi cha mpweya sichiyenera kupitirira 80%.
2.Substrate kutentha pa ntchito ndi kuchiritsa ayenera 3 ℃ pamwamba mame.
3.Kugwiritsa ntchito kunja ndikoletsedwa nyengo yoopsa monga mvula, chifunga, matalala, mphepo yamphamvu ndi fumbi lamphamvu.
Mapulogalamu
● 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.
● Pamene kutentha kwa chilengedwe ndi -5 ~ 5 ℃, mankhwala ochiritsira otsika ayenera kugwiritsidwa ntchito kapena njira zina ziyenera kuchitidwa kuti zitsimikizidwe kuti filimu ya penti ikuchiritsidwa.
