Kumanga kwakukulu kwa zigawo ziwiri za utoto wa epoxy, kukana bwino kwa mafuta osakanizika, zimbudzi, madzi a m'nyanja ndi nthaka, ma acid ofooka, maziko ndi mchere wina.
Mawonekedwe
1.Kupanga filimu yotchinga yolimba, yotupa komanso yosagwira ntchito yokhala ndi kukana kwambiri kulowa mutatha kuchiritsa.
2.Kulimbana ndi kukokoloka kwa nthawi yaitali ndi madzi, zimbudzi, madzi a m'nyanja, ndi nthaka.
3.Kukana kulowetsedwa ndi mafuta amafuta, gasi/dizilo, palafini wandege, mafuta opaka mafuta.
4.kukana kwabwino kwa ma asidi ofooka, maziko ofooka, ndi mchere wina.
5.Kusinthika kwabwino kwa filimu yophimbidwa ndi chitetezo cha cathodic.
Analimbikitsa ntchito
Oyenera chitetezo chachitsulo ndi konkire m'malo owononga kwambiri komanso malo omwe amatha kuwonongeka, monga malo oti alowe m'mphepete mwa nyanja, malo osiyanitsidwa ndi mafunde, ndi malo opunthira mafunde komanso ma wharves, zipata zama hydraulic, mapaipi apansi panthaka, ndi zina zambiri.
Amagwiritsidwa ntchito popaka anti-corrosion ya akasinja amadzimadzi komanso khoma lamkati la akasinja osungira.
Malangizo Ogwiritsira Ntchito
Chithandizo cha substrate ndi pamwamba
Chitsulo chopanda kanthu:kuphulika kutsukidwa kwa Sa2.5 (ISO8501-1) kapena osachepera SSPC SP-6, kuphulika mbiri Rz35μm~75μm (ISO8503-1) kapena chida mphamvu kutsukidwa kuti osachepera ISO-St3.0/SSPC SP3
Zoyambira pamwamba pa msonkhano wophimbidwa kale:Ma welds, kuwongolera zozimitsa moto ndi zowonongeka ziyenera kutsukidwa ku ISO-Sa2½, kapena chida chamagetsi chotsukidwa mpaka St3.0
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
● 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.

Chophimba Choyambirira & Chotsatira
Chovala choyambirira:Kugwiritsa ntchito molunjika pamwamba pazitsulo kapena epoxy yovomerezeka.
Chovala Chotsatira:Epoxy galasi flake, Polyurethane, Fluorocarbon ... etc.
Sizogwirizana ndi utoto wa alkyd.
Kupaka, Kusunga ndi kasamalidwe
Kuyika:maziko 25kg, kuchiritsa wothandizira 5kg
Pophulikira:>25 ℃ (Kusakaniza)
Kusungirako:Iyenera kusungidwa motsatira malamulo aboma.Malo osungira ayenera kukhala owuma, ozizira, olowera mpweya wabwino komanso kutali ndi kutentha ndi moto.Chotengeracho chiyenera kutsekedwa mwamphamvu.
Alumali moyo:Chaka cha 1 pansi pazikhalidwe zabwino zosungirako kuyambira nthawi yopanga.
