Party B's degreasing phosphating solution in Dongguan is said to be environmentally friendly, with no waste liquid discharged. Has anyone used it?

If you don't have high quality requirements, this potion is acceptable. I tried it on a rusty iron plate. I really just need not to wash it once, and the quality of powder spraying is ok. It's just that there is dirty dust and sand on the surface of the workpiece. Even if there is little phosphating slag in the liquid medicine, it will definitely be turbid after cleaning. They said they would get a device to filter it. I haven't tried this yet. Anyway, if you are interested, you can contact their website for door-to-door testing or send samples to try, and it is not necessary.
