Salting board is an important material used in purification workshops. Its application is to provide a reliable surface for adsorbing and removing harmful substances in the air, such as dust, bacteria, smoke, etc. Through its microporous structure and chemical properties, the salted board can absorb impurities in the air and fix them on the surface, thereby improving the air quality in the workshop, ensuring the cleanliness of the production environment, and improving the work comfort and health of employees.
