Anti-pombi yesimbi inoshandiswa zvakanyanya mumaindasitiri epetroleum, makemikari, uye gasi chaiwo. Yayo musimboti ndeyekudzivirira ngura uye kuwedzera hupenyu hwayo hwesevhisi kuburikidza nehunyanzvi maitiro. Iyo nzira yekushandisa inonyanya kusanganisira matanho matatu akakosha: kurapwa kwepamusoro, kuiswa kwekupotera, uye kuongorora.
1. Surface Treatment
Danho rekutanga pakuisa anti{0}}corrosion steel pipe ndeyekunyatsochenesa pasi kubvisa ngura, mafuta, uye oxide layer. Nzira dzakajairika dzinosanganisira sandblasting (Sa2.5 kana kupfuura) kana kemikari pickling kuti ive nehumwe hukasha hwepamusoro kuti uwedzere kunamira kwekunamira. Anti-corrosion treatment inofanira kushandiswa mukati memaawa mana ekurapwa kudzivirira kusanganiswa kweoxidation yechipiri.
2. Coating Application
Nzira dzakasiyana-siyana dzekunamira dziripo papombi inodzivirira-corrosion steel pipe, kusanganisira epoxy coal tar, 3PE (matatu-layer polyethylene), neFBE (fusion bonded epoxy powder).
Epoxy coal tar: Inoshandiswa nebhurashi kana kupfapfaidza, ine mabhachi maviri: primer uye topcoat, ine hukobvu hwese hweKukura kupfuura kana kuenzana ne0.6mm. Kuporeswa kunodiwa munzvimbo ine mwando kwemaawa makumi maviri nemana. 3PE Anticorrosion: Uchishandisa mhepo inomonereka, fusion-bonded epoxy powder inotanga kuiswa (base layer), inoteverwa nenamira nepolyethylene (yekunze layer), ine ukobvu hwese hweKukura kudarika kana kuenzana ne2.5mm. Inokodzera mapaipi akavigwa.
FBE Anticorrosion: Epoxy poda inopfapfaidzwa nemagetsi, ichinyunguduka patembiricha yakakwira kuti igadzire yakakora. Ukobvu hunowanzoita 400-1000μm, pamwe nepamusoro-soro yekudzivirira.
3. Kuongorora Kwehutano
Mushure mekupedzwa, kuongororwa kwakasimba kunodiwa, kusanganisira kuongorora kwekuona (kune mabhuru uye makatsemuka), kuyerwa kweukobvu (kuona kuti kutevedzerwa nemaitiro ekugadzira), kuona spark (kuona kuti hapana kudonha), uye kuyedzwa kwekunamatira. Nzvimbo dzisina kukodzera dzinofanirwa kugadziriswa nekukurumidza kuti ive nechokwadi chekudzivirira kusimba.
Chengetedzo: Pfeka zvekudzivirira panguva yekushanda kudzivirira kusangana pakati pepende neganda. Tembiricha yepakati inofanira kunge iri pakati pe5℃kusvika 40℃, uye humidity iri pasi pe85%. Kushanda kwakaringana kunogona kuvandudza zvakanyanya kuomarara kwepombi dzesimbi, kuve nechokwadi chekuchengetedza chirongwa uye hupenyu hurefu.
