1, pfapfaidza zinc anti-corrosion coating
Mushure mekupisa nodular cast iron pombi, muviri wepombi unopfapfaidzwa nekupisa kwakanyanya kunyungudutswa simbi zinc mhinduro kana tembiricha inosvika 600 degrees Celsius.Iyo zinc yekupfekedza mushure mekupfapfaidza ine yakanaka adhesion, haisi nyore kudonha, uye ine yakanaka anticorrosion performance.
2, asphalt pendi anti-corrosion coating
Asphalt coating ndiyo yekunze anticorrosion kurapwa kwemvura yakaoma uye gasi rekupa pombi muviri.Usati wapfapfaidza, iyo nodular cast iron tube body inopisa kusvika 80-100 madhigirii uye yobva yapfapfaidzwa.Mushure mekupisa, kupfapfaidza kunovandudza kunamatira kweasphalt layer uye inogona kuomeswa nekukurumidza.
3, simende dhaka lining + yakakosha anti-corrosion coating
Cement mortar lining anticorrosive layer iyi yemukati anticorrosive chiyero chakakodzera kutakura mvura yakaoma, uye kuburitswa kwepombi yetsvina yenyika, kupihwa kwemvura uye kubuda kwesuweji ine akasiyana emukati simende yekuputira dhaka, inogona kuvandudza kushorwa kweiyo ductile iron pombi madziro, ari oga. mvura uye cast iron layer, kuitira kuti irege kukonzera kusvibiswa kwemvura.
3, marasha epoxy asphalt anti-corrosion coating
Coal tar epoxy coating inokodzera zvese zvemvura uye mapaipi esuweji.Iyo ine zvikamu zviviri-zviviri sub coating ine yakakwirira adhesion uye yakanyanya kutsetseka.
4, epoxy ceramic mbavha yakaputirwa neanticorrosive coating
Epoxy ceramic lining inokodzera mapaipi ane zvakakwirira zvinodikanwa zvekupa mvura, kupihwa kwemafuta uye yakakosha kemikari mvura.Epoxy ceramic lining ine yakanyanya kunamatira uye kujeka kujeka, uye kushoma kushoma kwemvura kuramba.Iyo yakanakisa anti-corrosion coating.Asi neyakaoma yekugadzira maitiro yakakwira, yakakwira mutengo, saka pane zvimwe zvipimo mukushandiswa.
5, aluminate simende coating uye sulfate simende anticorrosive coating
Aya maviri akakosha masimende ekuputira akakodzera mukati anticorrosion yenodular cast iron mapaipi anoshandiswa mumapombi esuweji kuvandudza kushorwa kweasidhi uye alkali zvikamu mutsvina.
6, polyurethane anticorrosive coating
Polyurethane inonzi polyurethane, ndiyo ketani huru ine yakadzokororwa carbamate boka re macromolecular compounds.Inoumbwa ne organic diisocyanate kana polyisocyanate uye dihydroxyl kana polyhydroxyl compound copolymerization.Haisi chete ine yakanakisa kupfeka kuramba, kukanganisa kupikisa, kuputika kuramba, UV kuramba uye yakakwirira uye yakaderera tembiricha kuramba, ine simba rakawanda, yakakwirira kupfeka kusagadzikana uye solvent kuramba.Kuvhara kunodhurawo kugadzira.
