Questions about the selection and use of anti-static clothing
Environmental cleanliness also put forward different requirements. The latest foreign technology has enabled the cleanliness of the production environment to reach the level of Class 1 (that is, no more than one dust particle larger than 0.3 microns in a cubic meter of space). This requires that the clothes worn by the operator not only have anti-static properties, but also must have no dust, and can effectively block the tiny dust generated by human metabolism from passing through the clothes and entering the clean environment. This is due to the use of ultra-clean fabric anti-static clothing.
Because most companies lack professional knowledge of anti-static clothing, it is easy to damage the quality of products due to the selection of inappropriate fabrics, and even cause casualties. Therefore, "the choice of suitable anti-static fabric clothing is a matter of life."
1. First, we need to know what is the clothing made of anti-static fabric? Clothing made of anti-static processed fabrics can be called anti-static clothing. The antistatic processing methods of clothing fabrics usually include: ①The fabric is finished with an antistatic finishing agent; ②The fiber grafting modification, the blending and interweaving of hydrophilic fibers for the purpose of improving the moisture absorption of the fabric; ③The blending or embedding Woven conductive fiber;
Two, simple ultra-clean fabric anti-static clothing instructions
1. Wearing ultra-clean anti-static fabrics is as comfortable as ordinary anti-static fabrics, but you must know how to distinguish the two.
Measure the warp and weft density: use a warp and weft density mirror to measure the warp and weft density of the fabric and compare them.
Resistance measurement: use a surface resistance tester to measure the warp and weft resistance of the fabric and compare them,
2. Compared with ordinary fabric anti-static clothing, why ultra-clean fabric anti-static clothing is a good choice? Ultra-clean fabric anti-static has the following three functions at the same time. The difference between anti-static fabric and ordinary fabric is very important!
Efficient anti-static function: static electricity will attract dust and make it difficult to blow away when it is exposed to wind. Therefore, the primary feature of anti-static ultra-clean fabrics is anti-static properties. At the same time, this anti-static performance must be durable and efficient, and will not be significantly attenuated by daily washing and friction.
The clothing fabric itself does not emit dust, does not stick to dust, has good barrier properties, high density, high strength, and can effectively sterilize and inhibit bacteria;
Clothing fabrics are very dust-repellent: the dust in the clean room mainly comes from the air flowing in the room and the human body moving indoors. When the equipment conditions are determined, the cleanliness can be improved to control the dust and prevent it from being emitted into the air.
3. Precautions: Avoid contact with oil, grease and hydrocarbon derivatives; avoid contact with solvents dissolved in ketones and oxidizing acids, and nitrogenous organics; weak mechanical strength. Avoid contact with items containing ketone solvents and aromatic solvents
Anti-static clothing is already an indispensable product. It is recommended that you choose a good anti-static clothing carefully! While using it, use the anti-static knowledge you have to meet your needs! Be safe, reliable and healthy!
