ASA bathroom part water stain white spots
Problembeschreibung
White water stain spots appear on the surface of ASA bathroom and humid environment products, reduced after wiping but recurring, with continuous aesthetics complaints.
Ursachenanalyse
Hard water minerals deposit on the surface to form water stains; ASA surface microscopic defects and rubber phase distribution affect water stain adhesion; surface energy changes make water stains more conspicuous.; During on-site investigation, verify item by item according to this mechanism, avoid blindly adjusting the machine based on experience alone
Lösung
①Optimize product surface quality to reduce microscopic defects; ②if necessary, surface hydrophobic coating treatment; ③provide customers with cleaning and maintenance guidelines; ④verify the wipe resistance life of the surface treatment.
Wichtigste Erkenntnis
The ASA water stain problem is a comprehensive result of deposition and surface state; hydrophobic coating is an effective countermeasure; maintenance guidelines managing customer expectations are equally important.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
