Three Key Elements for Steel Surface Magnesium Duct Panel Production
One, Magnesium-based substrates must absolutely not exhibit salt efflorescence; the production process of magnesium chloride plates is prone to salt efflorescence, while magnesium sulfate plates are susceptible to alkali efflorescence.
Secondly, by not using substandard colored steel plates, acid-washed plates, and spray painting that skimps on quality, the composite colored steel plates are more prone to surface pattern issues.
Thirdly, use high-temperature-resistant adhesive, as general organic adhesives tend to produce black smoke and cause the color steel plate to fall off when exposed to fire.
