LW-14 is a kind of colorless to yellowish transparent liquid containing powerful degreasing surface active agent, emulsifier and functional agent. LW-14 can efficiently remove aluminum surface grease, stains and natural oxidation film and results no harm to aluminum profiles. It is used for pre-treatment of aluminum profiles powder coating. It has the advantages of simple process and less aluminum consumption.
|5-10min (Depends on the min surface conditions)
|1、Analyze LW-14 concentration and etching amount every day, and replenish in time.
|2、It is inevitable to bring in some insoluble substances such as mechanical debris and dust in the production process, so the bath solution should be cleaned up in time.
|3、Pay attention to the influence of temperature difference in winter and summer on etching amount and adjust the concentration in time to maintain the stability of etching amount.
