How to choose a clean wiper
There are many names for dust-free cloth: such as dust-free cloth, wiping cloth, purification rag, ordinary dust-free cloth, ultra-fine dust-free cloth and so on.
1. The choice of clean cloth:
1. Weight: depending on whether you choose a thicker dust-free cloth,
2. Variety and quality: Superfine fiber is relatively soft and polyester fiber is relatively thick, and the price varies depending on the actual material.
3. Softness: The softer the better, but it also depends on where it is used.
4. Abrasion resistance: The tougher the dust-free cloth, the better it will not drop chips.
2. The dust-free cloth can be divided into three types according to the sealing method: cold cutting, laser, and ultrasonic.
1. Laser cutting: The edge banding level is up to 99%, no chips, no dust, and the technology and cost are medium.
2. Ultrasonic cutting: better edge banding. No chipping, and the sealing edge is easy to tear and chip off after cleaning.
3. Ordinary cold cutting: The unsealed, dust-free embryonic cloth can be cut directly to ensure that it is easy to drop chips, and the technology and cost are low.
3. Quality inspection:
1. Whether there is an inspection report from the certification unit
2. Ion content: can it be within the scope of the reference test specification
3. Water absorption: Can it meet the needs of the product?
4. Wipeability: the stronger the better
5. Dust generation: the lower the better.
