How to judge the cleanliness of the cleanroom wiper?

 
Cleanroom wiper is a cleaning and wiping material widely used in electronics, medical, bioengineering, optics and other fields. Compared with traditional rags, dust-free cloths have the advantages of high cleanliness, strong adsorption, and no dust. It can be used to remove trace pollutants in dust-free environment (microelectronics, precision machinery, medical equipment and other industries), and is the most effective cleaning tool in dust-free environment. In different application fields, the clean room has strict grade standards. From high to low, cleanliness can be roughly divided into ten levels, one hundred levels, one thousand levels, ten thousand levels, etc. Each level of clean room should use the same level of clean cleaning consumables.
 
Nowadays, no matter which industry you are in, you must pay attention to quality, because quality is the lifeline of the normal operation of an enterprise. Only by paying attention to quality can you occupy a place in the market and industry. An important feature of the quality of the cleanroom wiper is its cleanliness. The cleanliness of the cleanroom wiper material is a key factor in determining the quality of the clean cloth. As a cleaning tool, clean cloth is essential. The cleanliness of the cleanroom wiper is stipulated by high standards and high requirements. Usually, how to judge the cleanliness of the cleanroom wiper? These are defined in several ways: 
 
 1. The amount of dust generated by the cleanroom wiper

This test is divided into two types, one is the amount of dust particles released in the air (APC). Many people think that shaking and falling debris is an intolerable problem for cleanroom wiper, but this is not the case. On the contrary, shaking and falling debris is the wiping material of cleanroom wiper It's a kind of medium property, just how high or low the shavings are. At present, it is mainly realized by Hank roller. The other is to detect the release of dust particles in the liquid (LPC), which is to soak the clean cloth in a certain amount of deionized water, and through ultrasonic oscillation, detect the concentration of dust particles in the deionized water.

 

2. The ion precipitation of the cleanroom wiper

Mainly check highly active metal ions and non-metal ions. If the surface to be wiped contains precision metal materials, it is recommended to take the precipitation of ions as an important detection item, because activated ions can easily damage the precision metal surface through battery reactions. Ion extraction is undoubtedly an important inspection item.

 

3. The number of non-volatile residues in the solvent of the cleanroom wiper

Residual precipitation: the amount of volatile matter in the solvent, which solvent is usually used, and which solvent is used to evaluate. The amount of residue is usually detected by sophisticated weighing equipment, but users can also determine whether the residue of this dust-free cloth meets the requirements according to whether it is fogged after wiping. To put it bluntly, it is the test of residues after use, mainly testing non-volatile substances. The test is the tissue composition of the clean cloth. In addition, the user can also determine whether the residue of the cleanroom wiper is within the required range by whether there is fog when wiping, but it is necessary to pay attention to the influence of the light, too strong light will affect the judgment.

 

The cleanliness of the cleanroom wiper by raw material textile enterprises is the main factor affecting the cleaning effect of the cleanroom wiper. High-quality products, every link can not be neglected. In this way, a lot of manpower, time and financial resources will not be wasted to put the finished product on the production line.
