Acacaanka PPGI Dhexeeya leh oo ka soo jeedda adeegga carruurta ah

Qarqor ahista ah waxaa loo sameyn karaa ku xiriirka PPGI, oo ka mid ah ugu yaraan effekta synergetic ee lacagta galvanized zinc iyo caafimaadka organic paint. Proseska galvanization wuxuu dejiyey lacag zinc aan ku soo gudbin steel substrate, oo uu ka mid ahayd qarqor ahista ah goobtii steel waxa uu ugu yaraan markaas: qarqorka badbaadaha, haddii lacag zinc ku jiraan steel si toos ah oo ku jiraan joogga, iyo qarqorka sacrificed, haddii lacag zinc ku jiraan si degdeg ah oo ku jiraan steel, haddii caafimaadka ku jirta oo lagu shaqeeya ama ku daraysa. Markaasa uu PPGI u baahan yihiin qarqor ahista ah oo la xiriirayo, maxaa yeelayaasha waxaa la xiriirayo fiican moisture, salts ama pollutants. Xiriirka lacag zinc waxaa isku soo saaraya ku caruurto, oo ku jiraan lacag zinc iyo aluminum (Zn Al) waxaa ku jiraan Galvalume® oo ku jiraan qarqor ahista ah oo la xiriirayo dhexdooda ama magaalada industrial haddii uu aluminum ka mid ahayd qab ilaa lacag oxide oo ku jiraan qarqor ahista ah. Caafimaadka waxaa ka soo baxday barakad ah, oo ku jiraan qarqor chemical attack iyo UV degradation oo ku jiraan lacag zinc ee ugu yaraan. Caafimaadka modern waxaa ku jiraan primers qarqor ahista ah oo ku jiraan bond lacag zinc iyo topcoat iyo qarqor extra ahista ah cut edges ama fastener sites. Qarqor ahista ah waxaa u socotay mekanikmada standardized oo ku jiraan salt spray test (ASTM B117), haddii samples ku jiran saline mist oo ka mid ah coastal ama winter road conditions, iyo cyclic corrosion test, oo ku jiraan wet iyo dry phases oo ka mid ah real world environmental fluctuations. Dhibaatooyinka uu ku jiraan qarqor ahista ah waxaa ku jiraan PPGI qaaritaanka qarqor ahista ah, oo ku jiraan users waxa uu soo jeeda grade kale oo la xiriirayo application. Haddii agricultural buildings ku jiraan exposure fertilizer salts ama offshore structures ku jiraan saltwater environments, qarqor ahista ah PPGI waxaa ku jiraan long term reliability iyo maintenance costs oo la xiriirayo, oo uu ku jiraan material preferred in any setting haddii metal degradation waxaa la xiriirayo.
