Classifyductile iron zvigadzirwazvichienderana nemukati uye kunze coatings sezvinotevera:
1. Common coating
Ordinary portland simende dhaka yakaputirwa mukati apo zinc uye bituminous pendi yakapendwa kunze.
2. Iko kuvharwa kwemukati we sulfate simenti dhaka
Sulfate simende, inozivikanwawo sesimende yakakwira sulfate-resistant, ine yakanaka sulfate corrosion resistance uye kushandiswa kwakakura mukutakura mamwe masvikiro akanyanya kuita semvura yegungwa.
3.Kuputira kwemukati kwealuminate simenti mortar
Iyo ductile iron pombi yemutsetse wesuweji inoenderana ne ISO7186, EN598 uye GB/T26081 yakaputirwa nealuminium simende (inozivikanwawo se high-alumina simende) mukati, zvichikonzera kupikisa kwakanakisa kumarara kwemakemikari uye abrasive kuramba ayo akakodzera zvakanyanya kutakura mvura inonaya, tsvina yetsvina nemamwe marudzi emvura yetsvina yemumaindasitiri.
4.Zinc-Aluminium coating
Kunze kwekunze kwepombi yesimbi yakaputirwa neZinc-Aluminium coating (85% Zn + 15% Al) inorema 400g/m2, iyo inokodzera ivhu rine kukora kwakanyanya.
5. Iko mukati mekuvhara kwe epoxy ceramic
Iyo yemukati ye epoxy ceramic inogadzirwa ne epoxy resin, quartz poda uye mamwe ane yakaoma firimu ukobvu inopfuura 1000μm, uye yakanakisa corrosion resistance yemagetsi insulating midziyo inoita kuti ive nzvimbo yakasarudzika mukutakura tsvina yekanzuru, mvura yakadzoserwa, nezvimwe.
6. Epoxy resin seal coating
Iyo pombi yakakandwa ine epoxy resin sealing coating yakaenzana nesamende yemukati-lining yakavharwa ne layer ye epoxy resin sealing, iyo ukobvu inotemerwa zvinoenderana nehunhu hwekutapurirana svikiro, uye ine inoshamisa abrasive kuramba uye corrosion resistance.Nekuda kwechisimbiso chekuvharisa, kunaya kwezvinhu zvine njodzi kunodzivirirwa zvine mutsindo, zvinoyemurika kudzivirira kusvibiswa kune yekufambisa svikiro uye kwakakodzera kuendesa kunangana kwemvura yekunwa.
7. Polyurethane coating
Polyurethane coating yakagadzirwa ne bi-component polyurethane zvinhu kusvika pachiyero, uye kwete chete inoshanda seyemukati-lining zvinhu zvenodular cast iron pombi, asi seyakabatana kunze kwekukukurwa kusingachinjiki.Polyurethane coating ine zvakawanda zvakanaka zvakadai seabrasive resistance, yakanakisa kusaita ngura, kusapinda, kutsetseka kwepasi, diki diki rekudzivirira, mashoma anoputika eorganic compound, inoshamisa kuchengetedza zvakatipoteredza, nezvimwewo. Mamwe ma polyurethane coating ane ukobvu pamusoro pe900μm anonyanya kuiswa pa kutakura midzimu inoparadza kana masvikiro ane hutsanana hwepamusoro, kusanganisira mvura yakapfava, kuchenesa mvura yegungwa, mvura yemarara yekanzuru, mvura inoraswa mumaindasitiri, nezvimwe;uye mamwe ane ukobvu pamusoro pe700μm anonyanya kushandiswa kune ivhu nharaunda nekuora kwakasimba senge ivhu rakasvibiswa nemvura yemarara yeindasitiri kana nekushomeka kwakaderera.
