Abstract

The invention relates to an oil paint coating construction method under the high temperature and high humidity environment. Steel member oil paint coating construction is carried out in a machining plant in mainland, packaging for sea transportation is carried out, and assembly is completed abroad. The oil paint coating construction method is characterized by comprising the following steps that a, an oil paint system is selected; b, oil paint surface treatment is carried out; c, construction of epoxy paint at the first time and the second time is carried out; d, polyurethane finishing coat is applied, and unified coating is adopted; e, oil paint special part coating is carried out; f, wet film thickness and dry film thickness detection is carried out; g, adhesive force testing is carried out; and h, oil paint coating repairing is carried out. The oil paint coating construction method under the high temperature and high humidity environment has the beneficial effects that oil system selection is scientific and reasonable, coating is exquisite, oil paint coating quality is safe and reliable, steel member oil paint can stand the test of the serious atmospheric environment of high humidity, windiness and high salinity in tropical coastal zones, the aims of reducing cost and increasing efficiency are achieved, and the construction period is greatly shortened on the premise that safety is guaranteed.

Description

technical field [0001] The invention relates to a paint construction method for steel components, in particular to a paint coating construction method in a high-temperature and high-humidity environment. Background technique [0002] In the first phase of sintering project of Formosa Plastics Ha Tinh Iron and Steel Plant in Vietnam, the steel silos in the main batching room are divided into 5 types, namely return ore silos, mixing silos, fuel silos, serpentine silos, and limestone silos, a total of 36. The silo is composed of a circular cylinder, an annular base, a support, a cone and a top cover (the mixed ore steel silo has no top cover). The support is installed on the +16.3m concrete platform, the ring base is installed on the support, the lower half and the vertebral body are suspended below the 16.3m concrete platform, and the bottom flange is 3.5m above sea level. The diameter of the upper cylinder of the silo is Ø8.2m, the elevation of the top cover is +21.0m, and t...
