Two types of cleanliness particle detection
Source：
Author：
Cleanliness particle testing is a method of evaluating product quality by detecting the size and quantity of particulate matter, which is of great significance in industrial production and environmental monitoring. Cleanliness particle testing can be divided into two types: solid particle detection and liquid particle detection.
Solid particle detection is the use of equipment such as light microscopy or electron microscope to observe characteristics such as the shape, size and quantity of particulate matter to determine its content and distribution in the product. This method can be used to detect fine metal particles, plastic fragments, fibers and other solid impurities. Solid particle inspection equipment is often sophisticated and expensive, but it can provide highly detailed particle distribution information, helping manufacturers control product quality and defects in the production process.
Liquid particle detection is the detection of the size and quantity of particulate matter in a liquid by using techniques such as laser scattering. This method can be used to detect larger particles such as sand, cinder, etc. Liquid particle detection equipment is relatively simple and inexpensive, but it does not provide the detailed information provided by solid particle detection.
The advantage of cleanliness particle testing is that it can detect both solid and liquid particles, thus providing more comprehensive product quality information. In addition, cleanliness particle inspection can also provide control information during the production process, helping manufacturers detect defects and anomalies in products in a timely manner.
The disadvantage of cleanliness particle detection is that it requires the use of special equipment and technology, which requires high operator skills. In addition, it also has a certain amount of error and uncertainty, so multiple tests are required to improve the accuracy of the detection.
In summary, cleanliness particle detection is an important quality control method, which can provide product quality information and control information in the production process, but it also has certain shortcomings and uncertainties.
