Picleaner <additive for sulfuric acid pickling>
Picleaner is a descaling accelerator and corrosion inhibitor for sulfuric acid pickling.
Pickling additive that greatly improves problems such as oxidization, black or red smut residue, and pinholes,etc.
Types of Picleaners
Four types of picleaners
PicleanerＡ１：Corrosion inhibitor,deodorizer（Liquid）
PicleanerＨ１：Corrosion inhibitor,deodorizer（Liquid）
PicleanerＢ１：Descalling accelerator（Powder）
PicleanerＷ ：Descalling accelerator,
Corrosion inhibitor,deodorizer（Liquid）
There are three types of combinations
（PicleanerＡ１＋Ｂ１）
（PicleanerＨ１＋Ｂ１）
（PicleanerＷonly）
characteristics
Strongly suppresses pinholes peculiar to sulfuric acid pickling
・Even if the pickling time is extended or the pickling temperature rises (up to about 75 ° C),
oxidization and black smut are almost completely prevented, and the effect of suppressing
waste acid is maintained.
Strongly promotes scale and smut removal
・Pickling time is halved at maximum, and it is also effective in removing annealing smuts.
Consolidate pickling patterns to improve productivity in automatic
pickling lines
・Since long pickling time can be shortened and short pickling time can be
extended, pickling patterns can be integrated.
Patented
・Picleaner W (joint patent with Nippon Hyoumen kagaku, patent No. 5743480)
Other
・It has the effect of suppressing the odor generated in the pickling process and ontributes in the work environment.
