Acidity
The pH of any type of water treatment agent must be strictly controlled. Especially for solvent-based water treatment chemicals, the acidity index is more important, because the workpieces to be cleaned are finished products, and most of them are not treated. The quality of the water treatment chemicals directly affects the quality of the workpieces cleaned. Therefore, the acidity index represents the stability of water treatment chemicals and the quality assurance of the cleaned workpieces.
Moisture
The water content of solvent-based water treatment chemicals is also a very important indicator. In principle, the less water, the better, but it is impossible to be completely anhydrous in mass production and use, and each solvent has a certain water content. Acidity and moisture in water treatment chemicals are two interdependent indicators, which directly affect the quality of workpieces to be cleaned.
Non-volatile matter (residue)
The amount of non-volatile matter in the water treatment agent directly affects the cleanliness of the cleaned workpiece. Since the workpiece to be cleaned is soaked in the cleaning solution and then allowed to dry naturally, the non-volatile matter in the cleaning solution may directly adhere to the workpiece.
Toxicity
Toxicity is an important indicator of whether water treatment chemicals can be used. Although it has no direct impact on the workpiece being cleaned, it has a profound impact on humans and the environment, and it is also a major factor in whether we choose it today.
