Imibhobho enee Coatings for Anti-umhlwa
Iimveliso Intshayelelo
Imigangatho: Imigangatho yemibhobho egqunywe nge-anti-corrosion ibekwe yimibutho efana ne-American Society for Testing and Materials (ASTM), i-International Organisation for Standardization (ISO) kunye ne-National Society of Corrosion Engineers (NACE). Le migangatho ichaza iimfuno zezinto zokugquma, iindlela zokusetyenziswa, iinkqubo zovavanyo kunye nemigangatho yokusebenza.
Ukuhlelwa okusekwe kunyango lomphezulu: Imibhobho ene-anti-corrosion coatings ingahlelwa ngokusekelwe kuhlobo lwengubo esetyenzisiweyo. Iindidi eziqhelekileyo ziquka:I-Fused Bonded Epoxy (FBE) Ukwaleka I-Polyethylene (PE) okanye i-polypropylene (PP) yokwaleka I-asphalt okanye i-asphalt yokwaleka Ipeyinti etyebileyo yeZinc Ukwaleka I-Polyurethane yokwaleka I-Coal tela yokwaleka enamel.
Usetyenziso: Imibhobho ene-anti-corrosion coatings isetyenziswa ngokubanzi kumashishini ahlukeneyo, kuquka: I-oyile neGesi: Imibhobho esetyenziselwa ukuthutha i-oyile ekrwada, irhasi yendalo kunye neemveliso zepetroleum Amanzi kunye namanzi amdaka: kumanzi aphantsi komhlaba kunye nogutyulo lwamanzi aphantsi komhlaba kunye nogutyulo Ikhemikhali kunye nepetrochemical: yokuthutha imichiza eyonakalisayo kunye neeasidi zaselwandle. nakude nonxweme: kwimibhobho engaphantsi kolwandle kunye nezakhiwo ezikude nonxweme Iziseko zophuhliso: Zisetyenziselwa iibhulorho, iidokhi kunye nezinye izakhiwo ezivezwe kwiimeko ezimandundu zokusingqongileyo Le mibhobho ibalulekile ekugcineni imfezeko nobomi obude beziseko ezingundoqo ezibalulekileyo kunye neenkqubo zemizi-mveliso, ingakumbi kwiindawo ezinoburhalarhume okanye ezinomhlwa. Xa ucacisa okanye ukhetha umbhobho nge-anti-corrosion coating, kubalulekile ukubhekisela kwimigangatho efanelekileyo kwaye udibane neengcali zoshishino ukuqinisekisa ukuba i-coating ekhethiweyo ihlangabezana neemfuno ezithile zesicelo esijoliswe kuyo.
