Acid-washing quartz stone is used to remove the oxide scale on the surface of quartz stone with acid. The acids used in pickling generally include hydrochloric acid, sulfuric acid, hydrofluoric acid, etc. Due to environmental protection requirements and public security control requirements, the use of strong acids will become less and less.
The process of pickling: preparation of acid solution → pickling and soaking of quartz stone → rinsing → drying, etc.
