摘要:
A pretreatment apparatus for performing pretreatment before a painting process includes a treatment tank to be filled with a treatment liquid for degreasing and chemical conversion. A circuit section forms a circulation path for circulating the treatment liquid from the treatment tank to the treatment tank. A purifying section removes dust, chemical sludge and oil from the treatment liquid circulated to the treatment tank through the circulation path.
摘要:
The present invention relates to a corrosion-protective composition containing a wax, an unsubstituted or substituted polyaniline in a doped form and a liquid paraffin, and articles comprising the composition applied on a substrate. It also relates to a process for manufacturing the composition, wherein i) a first dispersion of a polyaniline in a doped form is prepared; and ii) the first dispersion of the polyaniline is combined with a wax component to sufficiently disperse the polyaniline therein, and to the use of the composition as a single layer coating for the protection against corrosion of a substrate in need thereof.
