Capability Statement Nov 2016 - Primas Dry Ice Blasting Paint from Cast Iron Bearing Housings in Perth, WA.
Primas Dry Ice Blasting was instructed to remove three coats of paint from eight cast iron
bearing housings. Five of the housings were mounted to large winders and had gear boxes
assembled. Two of the gear boxed had also had a motor assembled. Three of the housings
had not been mounted to winders and could be removed from the site for cleaning.
The bearing housings were coated with the manufacturer's original red paint and an
additional two coats of grey paint had been applied. The client requested that all layers of
paint be stripped from the housings so they could be repainted to the end user's
specifications. The client requested that the five mounted housings be cleaned in situ without damaging the assembled components or housings and the unmounted housings be cleaned at the Primas workshop.
Primas wrapped up the assembled gearboxes and motors and then carefully removed the
paint from the bearing housings. Care was taken to not over-blast on to the winders.
The paint was efficiently and effectively removed from each of the bearing housings without damaging any of the various components or substrates. Dry ice blasting did not damage or introduce secondary media to the winders, gearboxes or motors that the housings were mounted to. Dry ice blasting slashed the amount of time that would have been required if the housings had been removed and abrasive blasted.
