How to choose the right dust-free wipe for your product?

Dust-free cloth materials have now been widely used in various high-tech industries, from general consumer electronics to biopharmaceuticals, from general laboratories to satellite factories, wherever there is a clean room, a dust-free cloth is required. Choosing the right dust-free cloth has always been a headache for dust-free wiper customers. Today, I will analyze with you how to choose the right dust-free wiper for your product.



Dust-free wipes, commonly known as dust-free wipes in China, are special cleaning wipes for dust-free clean rooms. Compared with ordinary civilian wipes, there are similarities and differences. What they have in common is that they are all decontamination products, which require strong decontamination ability and no reverse pollution. The difference is that clean room rags focus on the removal of trace pollutants, and are required to be able to withstand the erosion of various solvents and have ultra-low dust generation, while civilian rags only require general lint-free water resistance. .

Dust-free wiping materials have now been widely used in various high-tech industries, from general consumer electronics to biopharmaceuticals, from general laboratories to satellite factories, wherever there is a clean room, dust-free wiping materials are required. It is the wide application of dust-free wiping materials that has formed a wide variety of dust-free wiping materials on the market. At present, the dust-free wiping materials on the market mainly include the following categories: 1) Polyester knitted wiping cloth; 2) Polyester knitted knitted cloth Wiping cloth; 3) Polyester woven cloth; 4) Wood pulp/viscose and polyester composite non-woven cloth; 5) All polyester non-woven cloth; 6) All wood pulp non-woven cloth; 7) All PP Non-woven wipes; 8) PU sponge wipes; 9) PVA sponge wipes; 10) cotton woven knitted wipes, simply dazzling! I really don't know how to choose a dust-free wiping material!

According to years of practical experience, the correct selection of the required dust-free wiping materials should follow the following steps:

1. Identify the objects that need to be clear and the requirements for cleanliness

The so-called clean object, we need to determine what we mainly clean? Is it a general grease fingerprint, or some residual glue? Or general dust that is easy to remove? Are the cleaned surfaces exposed to high temperatures? How hard is the clean surface? Is there a requirement to prevent scratches? How much cleanliness needs to be achieved? Are there requirements for silicone-based pollutants? Sensitive to contamination ions?

2. Determine the compatibility with the solvent used

We all know that dust-free wiping materials are polymer materials, and in the process of cleaning, we must use organic solvents for cleaning, but there is one problem we must pay attention to, that is, to what extent are our wiping cloths? Can tolerate our organic solvents? How soluble is our wipe material itself in the 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 wiper. The closer the solubility parameter of the wiper is to that of the solvent, the better the wiper The easier it is to be dissolved by the solvent! This is something we don't want to see.
