Ultrasonic cleaning agent should pay attention to the three key elements of ultrasonic cleaning agent is a kind of mainly used in the cleaning of large and medium mechanical and electrical equipment on the processing of mineral oil, animal and vegetable oil, mechanical oil, etc.. With the implementation of the new environmental law, the traditional gasoline, kerosene, trichloroethylene and other cleaning solvents were gradually eliminated, environment-friendly industrial cleaning agent started to become mainstream, more and more manufacturers are moving on to the development and promotion of such products, the emergence of a large number of such products on the market, a lot of procurement staff in the procurement do not start and do not know that one is in line with the needs of their own products, then Xiaobian now to introduce, what kind of ultrasonic cleaning agent can be environmentally friendly and suitable? 1, ultrasonic cleaning agent should be with the characteristics of low toxicity, environmental protection, no harm, waste degradation, wastewater discharge enterprises in accordance with national legal standard, and can provide a safe and healthy operation of production line workers to work environment. 2, ultrasonic cleaning agent should have certain applicability, to remove oil, stains, do not damage the surface of equipment may, to avoid the impact of electrical and mechanical equipment on work efficiency. 3, ultrasonic cleaning agent should choose high concentrated water based cleaning agent, the water-based type is because ultrasonic machine has heat shock process at work, solvent based cleaning agent as water-based so stable, may lead to the occurrence of an accident. High concentration technology can increase the effective dilution ratio and save the cost.
