The discharge of hold-washings and other residues by vessels carrying noxious or corrosive goods must be conducted in compliance with the state provisions for vessel sewage discharge and shall be truthfully recorded in the logbook.
To sum up the effect of chlorion corrosion on the process equipments and index in Bayer process alumina production,and analyse the main reasons of equipments unefficient caused by chlorion corrosion.
Abstract : When two different metals are placed in a fused alkali or alkaline-earth chloride bath, the more readily corrodible metal will deposit on the less corrodible one.
An investigation was made on the effect of rewelding on anti-corrosion properties of ultra-low carbon austenitic stainless steel based on intergranular corrosion test and stress corrosion test.
Research on the failure reasons of the cooling tube were carried out by means of macroexamination, thickness measurement, X ray diffraction, optical microscopy and chemical analysis.
The corrosion mechanism of sulphureous sewage was analyzed. The process condition for corrosion-proof construction was recommended. The safe operation measure of sulphureous sewage tank was proposed.
When two different metals are placed in a fused alkali or alkaline-earth chloride bath, the more readily corrodible metal will deposit on the less corrodible one.
The corrosion of reaction caldron in the aeroconcrete production is a difficult problem,it makes the service life of reaction caldron only half of the design life.
Abstract: The effect of the desaturation aging (DSA) treatment on the strength and the corrosion resistance of ultra high strength aluminium alloys were studied.
The organic litter will help to cushion trampling forces, limit the compactability of soils, release plant nutrients, and reduce the erosie forces of rainfall.
The passivation patinas and the composition of each phases becoming more homogeneous are moderator to the dealuminization corrosion of high aluminum bronze.
Among the treasure trove were marble statues, elegant vases, glistening jewelry and ancient coins and what looked to be a hunk of corroded metal that no one knew quite what to do with.
Nor, despite St Paul's aphorism, was the lure of lucre during the experiment (as opposed to the effect of thinking about it as a result of being primed) necessary as a corrupting influence.
As the drink enters your mouth, it's high acid content begins to erode the enamel on your teeth. And the microorganisms in your plaque start to feed off the sugar which can lead to cavities.
Among the treasure trove were marble statues, elegant vases, glistening jewellery and ancient coins and what looked to be a hunk of corroded metal that no one knew quite what to do with.
The lawn and drive had been crowded with the faces of those who guessed at his corruption—and he had stood on those steps, concealing his incorruptible dream, as he waved them goodbye.
In the lab, adult teeth soaked in white wine for a day suffered a loss of both calcium and a mineral called phosphorus to depths of up to 60 micrometers in the enamel surface, which the researchers say is significant.
