Anti-corrosion kurapwa maitiro eiyo sound barrier column:
1. Kubvisa ngura uye kurapwa kweanticorrosive kwemakoramu anodzivirira ruzha uye zvidzitiro zvinosangana nezvinodiwa zvemagadzirirwo uye akakodzera mirau, uye ichaenderana nezvinodiwa zve "Technical Conditions for Anticorrosion of Steel Structures for Expressway Traffic Engineering" (GB / T18226).2.Asati apinda inopisa-dhipi galvanizing of inzwi chipingamupinyi nhengo, nhengo anofanira electrolytically pickled kuita hwaro simbi pamusoro yakachena.3.Simbi structural zvikamu zvipingamupinyi ruzha zvinofanira pamusoro pamusoro anticorrosive kurapwa inopisa-dip galvanizing uye epurasitiki spraying pashure galvanizing.4.Kupisa-dip galvanizing treatment: Zinc inoshandiswa pakupisa-dip galvanizing haifaniri kunge yakaderera pane yakakosha Nhamba 1 uye No.
Kuwanda kweplating ye zinc layer haifaniri kunge iri pasi pe610g / m2, uye chiyero chepakati chezinc layer hachifaniri kunge chiri pasi pe85um.5.Plastic coating mushure mekuputika kwechivharo chemheremhere: Zinc ingot inoshandiswa galvanizing (mukati. layer) ine zvinodiwa zvakafanana neyekupisa-dip galvanizing kurapwa.Pazasi 61um.Non-metallic coating ukobvu: polyvinyl chloride, polyethylene haafaniri kuva asingasviki 0.25mm, polyester haafaniri kuva asingasviki 0.076mm.6.Iyo anti-corrosion kurapwa kweruzha chipingamupinyi kunofanirwa kuitwa mushure mekunge chikamu chekugadzirisa chapera uye kuongorora kwacho kwakakodzera.Kana iyo chikamu mushure meiyo-anti-corrosion processing inogadziriswa zvakare, iyo yakagadziriswa nzvimbo inofanira kunge inopesana nekuora.
