Antirust varnish ndeye ngura-uchapupu hwekuchengetedza simbi kubva mumhepo, mvura uye mamwe makemikari kana electrochemical corrosion coatings.Zvikuru zvakakamurwa kuita ngura yemuviri nemakemikari mapoka maviri.Iyo yekare inotsamira pane yakakodzera pigment uye pendi nekuumbwa kwe dense firimu kudzivirira kupindira kwezvinhu zvinopisa, senge iron oxide tsvuku, aluminium poda, graphite ngura, nezvimwewo;iyo yekupedzisira nemakemikari kudzvinyirira ngura inokonzeresa pigments, senge tsvuku Dan, zinc yellow rust uye zvichingodaro.Zvemabhiriji, ngarava, mapaipi uye dzimwe simbi ngura.

Parizvino inoshandiswa anti-ngura pendi ingangoita marudzi maviri emafuta nemvura.Oil greasy surface rust kubviswa kwezvinhu zvakaoma, izvo zvave zvisingawanzo kushandiswa.Ngura yemafuta iri nyore kushandisa, isingadhure, asi ine nitrite, chromate uye zvimwe zvinhu zvine muchetura zvinokuvadza kune anoshanda, nyika ine mashoma ekushandisa uye kuita kwechinhu chimwe chete chakadaro hachikwanise kusangana nezvinoda anti-magnetic alloy zvinhu ngura.

Yakasimba mvura-based metallic rust metal chelator yakasarudzwa sechinhu chikuru che inositol hexaphosphate, uye mamwe akawanda ekuwedzera emvura akasanganiswa pamwechete.Phytate inotorwa kubva kune yakasikwa isiri-chepfu zvirimwa organic makemikari zvigadzirwa, kana inoshandiswa semagnetic rust inhibitor inogona kukurumidza pamusoro pepamusoro nesimbi chelate, ichigadzira dense single-molecule complexes kudzivirira membrane, iyo inogona kunyatso kuvharira ngura. zvesimbi.Chigadzirwa chacho chinogadziriswa nepamusoro pezvinhu kuchengetedza ruvara, kupenda uye saka haufaniri kuenda kunogeza nzira inotevera.

Ngura ngura pigments chikamu chinokosha chemuviri ngura pendi ikirasi pachayo chemikemikari yakagadzikana pigments, ivo vari kuvimba nezvinhu zvavo zvepanyama, kugadzikana kwemakemikari, zvakaoma, zvimedu zvakanaka, kuzadza kwakanakisisa, kuwedzera kuwanda kwefirimu, iyo firimu inogona. kuderedza permeability uye nokudaro kuita basa mukurwisa ngura.oxide tsvuku munyaya yezvinhu zvakadaro.nepo simbi inokonzerwa nengura aluminium aruminiyamu ine scaly chimiro, gadzira pendi membrane padhuze pane yakasimba ultraviolet mwenje inotaridza kugona kuvandudza kugona kwefirimu kuchembera.
