Abstract
The invention relates to the technical field of steel corrosion prevention and discloses a steel bridge corrosion prevention technology. Steel bridge components, chromium-free passivating fluid and antirust paint are included. The corrosion prevention technology comprises two steps, namely the overall corrosion prevention treatment and connection position corrosion prevention treatment; component overall corrosion prevention treatment is conducted before the components are connected, and after a steel bridge is connected, connection position corrosion prevention treatment is conducted; the component overall corrosion prevention treatment adopts the chromium-free passivating fluid electrogalvanizing method, and two times of electrogalvanizing treatment are conducted after dirt on the surface is cleaned up; the connection position corrosion prevention treatment adopts the thermal zinc spraying method, molten zinc is blown and adsorbed to the surface of the connection position after the dirt on the surface of the connection position is cleaned up, and pores are closed through the antirust paint. The steel bridge corrosion prevention technology is good in corrosion prevention effect, long in corrosion prevention time and high in industrial degree.
Description
Technical field
The present invention relates to steel anti-corrosive technical field, particularly a kind of steel bridge aseptic technic.
Background technology
Along with the quickening of urban development speed, the effect day of Urban Bridge is aobvious outstanding, wherein, because the intensity of steel bridge is high, from heavy and light, there is good plasticity and toughness, supporting capacity be strong, active time is long, short construction period, thus be subject to extensive concern, increasing Urban Bridge selects Approach To Steel Bridge Designing.But the shortcoming that steel bridge gets rusty easily seriously constrains the development of steel bridge, and the survey showed that, the loss that China causes because of metallic corrosion is every year approximately 4% of gross national product.For ensureing that steel bridge long-term safety within design period uses, carrying out the anticorrosion of steel bridge and just seeming particularly important.
Summary of the invention
The invention provides a kind of steel bridge aseptic technic, this aseptic technic industrialization degree is high, favorable anti-corrosion effect, and the anticorrosion time is long.
The present invention is achieved in the following ways: a kind of steel bridge aseptic technic, comprise steel bridge component, chromium-free passivation liquid and rust-inhibiting paint, it is characterized in that, described a kind of steel bridge rotproofing is divided into overall rotproofing and junction rotproofing, before transom, carry out member integrated rotproofing, after steel bridge has connected, carry out junction rotproofing.
Described overall rotproofing adopts the process of chromium-free passivation liquid passivation electro-galvanizing method, first the iron rust on member integrated surface, greasy dirt etc. are removed clean, coarsen treatment, then component is immersed described chromium-free passivation liquid plating 30-60 second, 30 seconds are left standstill in air, immerse again in chromium-free passivation liquid and electroplate 30-60 second, dry at taking out latter 40 DEG C-70 DEG C.
Described junction rotproofing adopts the process of hot spray painted zinc method, first junction iron rust, greasy dirt etc. are removed clean, coarsen treatment, then utilizes acetylene-oxygen flame to be melted by zinc silk, and blow with pressurized air and be attached to surface, junction, close pore with coating such as rust-inhibiting paints.
Advantage of the present invention is to improve steel bridge preservation industry degree, and favorable anti-corrosion effect, the anticorrosion time is long.
Embodiment
The present invention is further illustrated below by embodiment.
Embodiment one: the iron rust of steel bridge component surface, greasy dirt are carefully removed totally, its surface is made to expose metalluster, then coarsen treatment, then component is immersed chromium-free passivation liquid and electroplate 30 seconds, take out and leave standstill 30 seconds in atmosphere, then component is immersed chromium-free passivation liquid and electroplate 30 seconds, dry at taking out latter 40 DEG C-70 DEG C, now component surface entirety has been electroplate with one deck zinc, and overall rotproofing completes.Component is coupled together by welding or alternate manner, the greasy dirt of junction etc. is removed clean, expose coarsen treatment after metalluster, then with acetylene-oxygen flame, the zinc silk constantly sent is melted, and blow with pressurized air and be attached to surface, junction, finally close pore with coating such as rust-inhibiting paints, junction rotproofing completes.
A kind of steel bridge preservative treatment technology of the present invention has outstanding preservative effect, and the anticorrosion time is long, and industrialization degree is high, and the treatment time is short.
