Dhammaadka Tirfad ee Polyurethane Coated | Degmada Ugu Dhexe & Koroshada Kor

Qarqaradka qalabka urethane coated waxaa ka soo jiray xogga dhammaan ee qalabka iron ah oo ah mar kale ugu badan anti corrosion performance ee polyurethane coating, kuwaas oo ay ku yimid maamulka dhammaan ee koodka fikradaha. Qalabka iron ah oo ah mar kale ugu badan ah intaas oo ah strength iyo toughness. Graphite ee aan ku jiray matrix ee uu ku jiray haddii spherical nodules, waxay ku sameyn doonaa ductility iyo impact resistance ee material ee uu ku jiray, si aad ugu yaraan gray cast iron, si aad ugu yaraan qarqaradka ah ugu badan pressure iyo external force ah oo aan ugu jiro cracking ama deforming. Polyurethane coating, wuxuu ah synthetic material ee la isaga dhigay, wuxuuna uga yaabaa protective layer ee ku jira dense iyo continuous oo ku jiray surface ee qarqaradka. Layerka ah waxay ku jiran chemical stability ee ugu badan, waxayna uga yaabaa erosion ee caawimaadka ah oo ah acid, alkali, salt, iyo organic solvents ee ah soil iyo water, oo wuxuuna ku jiran wear resistance ee la mid ah friction damage ee uu ku jiray bayn medium iyo pipeline during transportation iyo installation. Markaanti ah anti corrosion mechanism, polyurethane coating wuxuu ka mid ah physical barrier ee ku jiray isolation ee qarqaradka ee qalabka iron ah ee corrosive environment, oo wuxuu ka mid ah flexibility ee ugu badan. Waxay uga yaabo integrity ee coatingka markii qarqaradka ah ugu jiro external forces, si aad ugu yaraan cracking iyo peeling ee coatingka, kuwaas oo ay ku yimid long term iyo reliable anti corrosion protection ee qarqaradka. Markaanti ah practical applications, polyurethane coated ductile iron pipes waa inaad ugu yimid water supply systems, sewage treatment projects, iyo caawimaadka ah. Marka water supply systems, waxay ku yimid quality ee drinking water ah, sababtaas oo polyurethane coating waa non toxic iyo harmless, oo wuxuu ku jiray health requirements ee water supply. Marka sewage treatment projects, waxay ku yimid resistance ee uu ku jiray harmful substances ee ah sewage, si aad ugu yaraan stable operation ee long term ee pipeline. Construction iyo installation ee qarqaradka ah waa inaad ugu yimid convenience ee ugu badan. Waxay uga yaabo connection methods ee ugu badan oo ah flexible joints, kuwaas oo ay ku yimid sealing performance ee pipeline, oo waxay ku yimid flexibility ee ugu badan ee pipeline ee uu ku jiray slight ground settlement ama displacement, si aad ugu yaraan pipeline leakage. Marka urbanization ee ugu badan ah iyo demand ee infrastructure construction ee ugu badan ah, application prospects ee polyurethane coated ductile iron pipes waa inaad ugu yimid broadness ee ugu badan. Xogga dhammaan ee ay ku jiray needs ee high quality iyo long life engineering construction, oo wuxuu ku yimid reliable guarantee ee safe operation ee water supply iyo drainage systems ee dhexe.
