What kinds of acids are used for quartz stone pickling?

Acid washing is a common processing method for quartz stone, primarily used to remove impurities and improve its appearance and performance. During acid washing, the acids used primarily react with specific components in the quartz stone to dissolve unwanted substances. The following is a detailed explanation of the types and quantities of acids used in quartz stone acid washing.

First, acid washing of quartz stone typically involves multiple types of acids, commonly including hydrochloric acid, nitric acid, and phosphoric acid. These acids have different chemical properties, and the appropriate acid combination can be selected based on specific needs and the characteristics of the quartz stone. For example, hydrochloric acid can react with certain metal ions, and phosphoric acid can react with specific mineral components in quartz.

In practice, the selection of acid type and concentration depends on the composition of the quartz stone, the desired processing results, and experience. For simple cleaning and processing, a single acid may suffice. However, for more complex or demanding processing, a combination of two or more acids may be needed to achieve better results.

In addition to selecting the appropriate acids, the acid washing process also needs to consider factors such as acid concentration, temperature, and processing time. These factors will affect the outcome of the acid washing and the quality of the quartz stone. For example, high-concentration acid may achieve processing results faster, but it may also cause greater damage to the quartz stone; low-temperature processing may require more time, but it can reduce damage to the quartz stone.

In summary, acid washing of quartz stone involves the use of multiple types of acids, and the specific acid or acids used depend on the actual situation.
