BRICK COMPANY ENGLAND APRON
ROOF OVER BRICK KILNSConstruction being a mixture of steel and galvanized steel uprights, girder beams, H irons and I beams with concrete foundations. In all housing an extremely corrosive environment compounded with thermal shock to the substrates.
The Brick Kilns during the firing of the bricks continuously emit extremely hot moist fumes of sulphur, phosperous, and nitrogen plus other acidic corrosive gases attacking all metal substrates and the surface of concrete foundations supporting the whole roof superstructure combined with the additional hazard of the brickworks being situated on a hillside with prevailing winds carrying brick dust creating a sand blasting environment attacking all painted surfaces.
THE PAINT SYSTEM CHOSEN
Two coats of Neutra Rust 661 Rust Converter were applied DFT 60
microns and over-coated with three coats TL BARRIER, white, red and grey
DFT 150 microns, total overall DFT 210 microns. On the concrete
foundations, three coats of TL BARRIER were applied, white, red and grey,
total DFT 150 microns.
IRAN - the unique patented Darya Paye Jetty
Neutra Rust TL BARRIER with its outstanding physical properties was
the coating specified for this extremely difficult Jetty installation
situated in a highly corrosive environment of salt water and desert sand
compounded by extreme day and night temperatures inducing thermal shock to
the substrates. Due to the irregular shapes and sizes of the pilings,
castings and substrate, the TL BARRIER coatings also had to resist
severe mechanical handling, abrasion and impact damage during the
construction of the Jetty.
The whole structure - girders - uprights - platforms and concrete foundations were in a severe state of corrosion, but due to the time factor to complete the painting contract, closing down the firing of the brick kilns was ruled out on economical grounds.
Blasting back to bright metal was also eliminated, as the acidic fumes from the kilns would contaminate the blasting surface. Therefore commercial sweep blasting was recommended to remove the loose rust and old blistered paintwork followed by high pressure hosing to remove the acid contaminated deposits.
