Pakupedzisira, ivo vanobikwa uye vanoporeswa kuti vaumbe. Nekuti iyo pamusoro yakaputirwa neiyo organic coil yeakasiyana mavara, iwo mavara esimbi coil anotumidzwa zita ravo, uye anoshevedzwa semavara akavharwa simbi coils.
Nhoroondo Yebudiriro
Mashizha akavharidzirwa nesimbi akatanga kuUnited States pakati pemakore ekuma1930. Pakutanga, dzaive tumarata twakapendwa, twainyanya kushandiswa kugadzira mapofu. Nekuwedzera kwehukuru hwekushandisa, pamwe nekuvandudzwa kweindasitiri yekupotera, pretreatment kemikari reagents uye maindasitiri otomatiki tekinoroji, yekutanga yakakura-bhendi coating unit yakavakwa muUnited States muna 1955, uye machira akagadzirwawo kubva kune yekutanga alkyd resin pendi kuenda kumhando dzine simba rekudzivirira mamiriro ekunze uye inorganic pigments. Kubva kuma1960, tekinoroji yakapararira kuEurope neJapan uye yakakurumidza kukura. Nhoroondo yebudiriro yemakoiri akavharwa nemavara muChina angangoita makore makumi maviri. Mutsara wekutanga wekugadzira wakaunzwa neWuhan Iron and Steel Corporation kubva kuDavid Company kuUK muna Mbudzi 1987. Inotora advanced-coating maviri uye maviri-ekubikira maitiro uye roller coating kemikari pretreatment tekinoroji, ine yakagadziridzwa yegore yekugadzira inokwana matani 6,4. Zvadaro, Baosteel's color coating unit equipment yakaiswa mukugadzirwa muna 1988, yakaunzwa kubva kuWean United kuUnited States, ine hupamhi hwekumhanya kwemamita 146 paminiti uye yakagadziridzwa yegore yekugadzira matani makumi maviri nemaviri. Kubva ipapo, zvigayo zvesimbi zvepamba uye mafekitori akazvimiririra akazvipira pakuvaka mitsara yekugadzira yakavharwa nemavara. Indasitiri yecoil yakavharwa nemavara yakasimukira nekukurumidza uye yave kuita indasitiri yakakura uye yakakwana.
