Micronized Nano Zinc Oxide

Micronized nano zinc oxide has important applications in nano anti-ultraviolet finishing agents; Nano anti-ultraviolet finishing agent refers to the use of light-resistant stabilizer micronized nano zinc oxide as the base material, and the use of polymer nano-encapsulation technology to prepare a stable dispersion type finishing agent with a particle size of 20 to 80 nm. Through the curing method, the light stabilizer particle nano zinc oxide enters the fiber in the form of nano particles and is fixed on the fiber, so that the fabric has excellent UV resistance. micronized nano zinc oxide enters the fiber or fixes on the fiber surface with nano particles, and can obtain the durability function by curing.

Application characteristics of nano anti-ultraviolet finishing agent made of Micronized nano zinc oxide:

1. Nano anti-ultraviolet finishing agent made of Micronized nano zinc oxide is used as a light fastness enhancer: it can effectively block and absorb UVA (wavelength 320-400nm) and UVB (280-320nm), and the UV shielding rate is 99 % Or more; improve the light fastness of dyed materials by 1-1.5 grades, and meet the needs of some customers with high temperature fastness requirements.

2. Nano anti-ultraviolet finishing agent made of Micronized nano zinc oxide is used as a functional anti-ultraviolet finishing agent: it can make the fabric become a functional textile with excellent anti-ultraviolet performance, and enhance the added value of textiles. The transmittance of ultraviolet can be controlled Within 3%.

3. Nano anti-ultraviolet finishing agent made of micronized nano zinc oxide is a non-ionic product, which has no adverse effects on the shade, hydrophilicity, and hand feel of the fabric, and will not cause yellowing, hydrophobic, hard feeling and other problems; it It can be used in combination with other ionic or non-ionic finishing agents to obtain multiple effects.

4. Nano anti-ultraviolet finishing agent made of micronized nano zinc oxide enters the fiber or fixes on the fiber surface with nano particles, and can obtain the durability function by curing.
