The
nanometer titanium dioxide for plastic is white fluffy powder, with small
particle size and uniform particle size. It adopts nano-silicon-aluminum
composite dense inorganic coating, and the powder undergoes special organic
treatment to form a dense layer of silicone and titanate on the surface of the
powder. The membrane improves the dispersion properties of the powder and
avoids secondary agglomeration of the powder. The treated nano-titanium dioxide
powder can be subjected to a subsequent crosslinking reaction with the resin
during use to enhance the binding force between the resin and the powder. It is
used in plastics to significantly improve the aging resistance and mechanical
properties of plastics, and has a strong antibacterial effect.

Application
features:
Adding
rutile nano titanium dioxide (DK-TiO2-T30) to plastic not only plays the role
of white pigment, but also improves the heat resistance, light resistance and
weather resistance of plastic products, and the physical and chemical
properties of plastic products are obviously improved and enhanced. The
mechanical strength of the product and prolong its service life. Nano titanium
dioxide (for plastics) has the following advantages in plastics compared to
ordinary titanium dioxide:
1.
Rutile nano titanium dioxide (DK-TiO2-T30) has good absorption properties for
UVA and UVB, and can effectively absorb ultraviolet light. The plastic is
damaged by sunlight, which helps to prevent cracking, fading and other
photodegradation of plastic products. This product blocks UV light irradiation
performance more than three times higher than ordinary titanium dioxide.
2.
The strength, toughness, aging resistance, heat resistance and impact
resistance of plastics are increased several times.
3.
The UV shielding, antistatic properties and tensile properties of plastics are
significantly improved.
4.
The surface of the nano-titanium dioxide (DK-TiO2-TA30) film has a high
self-cleaning effect.
5.
nano titanium dioxide (DK-TiO2-TA30) has obvious bactericidal, antibacterial
and antibacterial effects on harmful bacteria.
6.
Add nano-titanium dioxide (DK-TiO2-TA30) to plastic products to accelerate the
degradation rate of plastic products.
Application
range:
1.
As a light stabilizer, used in sunscreen plastics, including sporting goods,
outdoor facilities, fabrics and carpets.
2.
Antibacterial plastic: can be used for children's toys, food wrap, packaging
bags, electrical appliances, furniture, tableware, public facilities and so on.
3. Easy to degrade
plastic: widely used in disposable film, disposable lunch boxes, agricultural
film, plastic bags. |
