How to choose a suitable dust-free cleanroom wiper
1. Find out what needs to be clear and the requirements for cleanliness:
The so-called cleaning object, we need to determine what we mainly remove? Is it general grease fingerprints, or some residual glue? Or general dust that is easy to remove? Does the cleaned surface have high temperature? How hard is the cleaned surface? It can prevent scratches Are there any requirements? How high is the level of cleanliness that needs to be achieved? Are there requirements for organic silicon pollutants? Is it sensitive to polluting ions?
2. Determine the compatibility with the solvent used
Dust-free wiping cloth materials are all polymer materials. In the process of cleaning, we must use organic solvents for cleaning. However, we must pay attention to one problem, that is, to what extent our materials can withstand our organic Solvent? What is the solubility of our wiping material itself in solvent? This is the problem of the solubility parameter of polymer materials. It is recommended to check the solubility parameter first when choosing a better wiping cloth. The closer the solubility parameter is to the solubility parameter of the solvent, the easier it is for the wipe to be dissolved by the solvent.
3. Determine the type of dust-free material
Because the application of dust-free wipes is extremely wide, before choosing a wipe, first determine the advantages and disadvantages of various dust-free wipe materials:
Regarding how to choose dust-free wipes, we can determine the type of dust-free wipes we need based on our actual needs. If the main purpose is to remove grease or fingerprints, polyester-nylon composite superfine fiber dust-free wipes are more suitable, because this type of dust-free wipes have more contact with the surface, and the wiping effect is higher than that of ordinary fiber dust-free wipes. To remove residual glue that adheres tightly to the surface, a woven dust-free wipe will be more appropriate. If the surface temperature is relatively high, 100% wood pulp or 100% cotton dust-free wipes are more appropriate. If there is a requirement for silicone, the dust-free wipe should not contain silicone. If the wiping dust and the residual glue volume are relatively large, it is more appropriate to use a knitted material dust-free wipe with a relatively large pore size. In terms of how to choose a dust-free wiping cloth, in fact, the higher the requirement for surface cleanliness, the more we need to look for a dust-free wiping cloth with high cleanliness.
