Problems solved by technology

However, because phosphate will directly promote the proliferation of microorganisms in water, excessive consumption of oxygen in water, the discharge and accumulation of phosphate will pollute the water quality of rivers, lakes and seas, affect the survival of aquatic organisms and animals, and destroy the ecological balance. The discharge of this phosphorus-containing waste has been restricted by environmental regulations
[0003] In addition, the existing metal surface degreasing agents need to be differentiated for different metals (carbon steel, stainless steel, aluminum and aluminum alloys, zinc and zinc alloys, copper and copper alloys, titanium and titanium alloys, magnesium alloys, etc.), poor versatility , it is necessary to replace the bath solution according to the metal material, which brings more troubles to production and use, and increases the production cost
