[0002] In addition to its own cleaning performance that has a great impact on the product, the cleaning cloth used in the clean room also has an important impact on the product after cleaning and wiping. Even though the cleaning performance of the cleaning cloth product itself is very high, it can meet the needs of the environment, but in During use, if the particles fall off, fluff, and depilate due to wiping, it may seriously pollute the product. For example, the tiny particles on the hard disk may scrap the magnetic head in the disk, and the dander particles on the LCD screen will be damaged. Make white or black spots appear on the screen, but the usual detection method is only to test its own cleanliness, such as IEST-RP-CC004.3 of the National Environmental Association of the United States and my country's textile industry standard FZ / T 64056-2015, However, there is no actual control of the potential risks that may be brought about during the wiping process, especially the control of the risks caused by particles, dander, hairiness and other particles caused by friction during the wiping process

[0084] Such as Figure 4 As shown, take the dry state and isopropanol wet state test of 3g / piece, 6”×6” dust-free cloth sample 6 as an example:
[0085] 1. Prepare a package of 3g / piece, 6”×6” clean room dust-free cloth samples 6, and there should be at least 20 dust-free cloths 6 in the package.
[0086] 2. Prepare the following instruments and reagents:
[0087] 1) Class 5 (Class 100) or higher cleanliness laminar flow clean room or working environment specified in ISO 14644-1:1999.
[0088] 2) Industrial isopropanol meeting the requirements of GB / T 7814-2008.
[0089] 3) An optical microscope with a micrometer function, the minimum scale of the micrometer measurement is 100 μm, and the magnification is ≥40 times.
[0090] 4) 3mm thick colorless transparent flat glass 1 with an area of 24cm×24cm, grid lines 2 accurate to centimeters on the bottom surface, each grid is 1cm, and meeting the requirements of GB11614-2009. Wherein, the middlemost is a 4cm×4cm grid, the outs...

The invention discloses a method for detecting dust-free cloth to wipe dust amount for a clean room, which belongs to the field of dust-free cloth detection. The method comprises the following steps:preparing an apparatus and a reagent, performing dry-type wiping testing, performing wet-type wiping testing, and calculating. The method solves the defects on a particle detection method for particles, soft flocks and filoplume generated due to friction during a practical usage wiping process of the dust-free cloth in a current clean-room wiping cloth industry standard, and provides objective andreliable cleanliness data support and evaluation for the clean-room dust-free cloth, especially the high-cleanliness dust-free cloth under a dry-state or wet-state usage environment.
Description
technical field [0001] The invention relates to the field of dust-free cloth detection, in particular to a method for detecting the amount of dust generated by wiping a clean room with a dust-free cloth. Background technique [0002] In addition to its own cleaning performance that has a great impact on the product, the cleaning cloth used in the clean room also has an important impact on the product after cleaning and wiping. Even though the cleaning performance of the cleaning cloth product itself is very high, it can meet the needs of the environment, but in During use, if the particles fall off, fluff, and depilate due to wiping, it may seriously pollute the product. For example, the tiny particles on the hard disk may scrap the magnetic head in the disk, and the dander particles on the LCD screen will be damaged. Make white or black spots appear on the screen, but the usual detection method is only to test its own cleanliness, such as IEST-RP-CC004.3 of the National Envir...
