Application of COP cleaner
Types of COP cleaner: Water/acid foam/alkaline foam (ordinary foam/film foam/colloidal foam)
Principles for selecting COP cleaner: The particles can be separated from the surface and suspended in the cleaning solution as small particles; Does not produce lactoid/hard water and fatty acid salt precipitation; With surface activity, so that the precipitation surface is easy to soak, particles and cleaning solution are easy to be washed away by water; Does not corrode machinery and equipment; Easy to save; Low use cost; Or it may be approved by the government environmental protection department.
Factors to consider when choosing COP cleaner: object to be cleaned/type and characteristics of dirt/quality of water/method of cleaning/environmental requirements
Cleaning objects: stainless steel/carbon steel/copper/aluminum/non-metallic materials
Dirt type: oil/protein/carbohydrate/mineral salt
Oil removal: emulsification (surfactant) - dispersion (alkali) - saponification (strong alkali)
Removal of protein: Dissolved protein (base or acid) - hydrolyzed protein (oxidant) - catalyzed hydrolysis of protein (protease)

Removal of sugar and starch: Removal of sugar (warm water) - Removal of starch (alkaline or acidic cleaner + amylase)
Mineral salt removal: soluble in general acid cleaners, adding chelating agents to prevent scale formation
Environmental requirements: all sewage must be pre-treated before discharge; Must first neutralize the PH of the water to reduce the pollution of the link; Controlling the phosphorus content in sewage; Control BOD or COD in sewage.
The cleaning principle of the acid and alkali cleaning agent: the cleaning agent produces physical reaction in the dirt (change its solubility and surface adhesion);The cleaner reacts with the dirt (turning the dirt into a water-soluble substance);Adding surfactant can emulsify and suspend. In addition, the foam (colloid) has the coating and the mechanical function;
Cleaning steps: One step: water - basic foam/acid foam
Three - step method: water - alkali (acid) foam - water
Five - step process: water - basic foam - water - acid foam - water
