In kitchen, bathroom and other cleaning operations, foam nozzles can transform detergent into rich foam, easily cover and penetrate stains, reduce water consumption, and improve cleaning effect. For inaccessible corners and gaps, the permeability of foam can also help achieve comprehensive cleaning. In the manufacturing industry, foam nozzles are often used for spraying, cooling, lubrication and other processes. For example, in the field of automotive paint spraying, foam spraying technology can achieve uniform coverage and reduce paint waste; In the process of metal processing, foam coolant can reduce the temperature more effectively and protect tools and equipment.
