Inkqubo yonyango lokuchasana nokonakala kwekholamu yesithintelo sesandi:
1. Ukususwa komhlwa kunye nonyango lwe-anticorrosive yeentsika zokuthintela ingxolo kunye nezikrini ziya kuhlangabezana neemfuno zoyilo kunye nemimiselo efanelekileyo, kwaye iya kuthobela imimiselo echaphazelekayo "yeTechnical Conditions for Anticorrosion of Steel Structures for Expressway Traffic Engineering" (GB). / T18226).2.Phambi kokungena eshushu-dip galvanizing yelungu umqobo isandi, ilungu kufuneka electrolytically pickled ukwenza isiseko umphezulu metal icocekile.3.Izakhiwo zentsimbi zemiqobo yengxolo kufuneka zibe ne-anti-corrosive surface iphathwe nge-galvanizing ye-hot-dip kunye nokutshiza ngeplastiki emva kwe-galvanizing.4.I-Hot-dip galvanizing treatment: I-zinc esetyenziselwa i-hot-dip galvanizing akufanele ibe ngaphantsi kweNombolo ekhethekileyo ye-1 kunye ne-1 ye-zinc ingot echazwe kwi-"Zinc Ingot" (GB / T470).
Isixa seplating somaleko we-zinc akufunekanga sibe ngaphantsi kwe-610g / m2, kwaye ubukhulu be-avareji ye-zinc layer kufuneka bungabi ngaphantsi kwe-85um.5.I-Plastic coating emva kwe-galvanizing yesithintelo sengxolo: Ingot ye-zinc esetyenziselwa ukugalela (ngaphakathi umaleko) uneemfuno ezifanayo nonyango lwe-galvanizing yediphu eshushu.Ngaphantsi kwe61um.Ubukhulu be-non-metallic ukutyabeka: i-polyvinyl chloride, i-polyethylene ayifanele ibe ngaphantsi kwe-0.25mm, i-polyester ayifanele ibe ngaphantsi kwe-0.076mm.6.Ukunyangwa kwe-anti-corrosion yesithintelo sengxolo kufuneka kwenziwe emva kokuba inkqubo yecandelo igqityiwe kwaye ukuhlolwa kufanelekileyo.Xa icandelo emva kokuba i-processing anti-corrosion icutshungulwa kwakhona, indawo esetyenzisiweyo kufuneka ibe yi-anti-corrosive.
