Testing of industrial cleaning agents

The testing of industrial cleaning agents mainly includes the following aspects:

PH value: The pH value of industrial cleaning agents is generally between 6 and 10. If it exceeds this range, it may lead to poor cleaning effect or cause corrosion to the cleaned object.

Specific gravity: Different types of cleaning agents have different densities, and testing the specific gravity can determine whether industrial cleaning agents are diluted or adulterated with water.

Active substance content: Commonly used industrial cleaning agents include surfactants, chelating agents, corrosion inhibitors, etc. Testing its content can determine the effectiveness and quality of cleaning agents.

Residue determination: For certain special industries (such as medical, semiconductor, food, etc.), the residual amount of cleaning agents needs to meet corresponding standards. The detection methods for residues mainly include chromatography, liquid chromatography, mass spectrometry, etc.

Metal ion content: If the metal ion content in the cleaning agent is too high, it may pose a corrosion risk to the cleaned object. The main detection methods include atomic absorption spectroscopy, inductively coupled plasma emission spectroscopy, etc.

Water quality testing: Some cleaning agents need to be mixed with water, so testing the hardness, pH value, solubility and other parameters of the water in the cleaning agent can determine its applicability and effectiveness.

The above are some basic testing methods for industrial cleaning agents. Different types of cleaning agents may require targeted testing methods, which need to be selected based on actual situations.
