First, the application of nano TiO 2 in plastics
Nano TiO 2 has good dispersibility in masterbatch and can prepare plastic packaging materials with high transparency. Not only can the food be seen through plastic packaging, but also the oxidative discoloration of meat products can be avoided, and the vitamins and aromatic compounds in the food can be protected from damage. At the same time, the plastic can be prevented from being degraded by sunlight, and the strength and durability of the agricultural film can be improved.
Second, nano-TiO 2 can synthesize methanol and decompose water
The nanometer TiO 2 photocatalyst can be used to synthesize methanol from CO 2 and water; and the nano TiO 2 single crystal and another Pt electrode can be used to electrolyze water into H 2 and O 2 under light irradiation.
Third, the application of nano TiO 2 in other aspects
Nano TiO 2 can also be used as a resin ink colorant, a silicone rubber reinforcing agent, an additive for a solid lubricant, a high-efficiency photocatalyst, an adsorbent, a catalyst carrier, and the like. In foreign countries, TiO 2 nanoparticles in sunscreen cosmetic aspect limousine metallic paint color, high voltage insulation material, the integrated circuit substrate, the fluorescent tube has been widely used. The light-colored, white or even transparent nano-TiO 2 has a decorative effect and a high reflection effect. Therefore, nano-TiO 2 is widely used in the electronics industry and the aerospace industry for electronic components, electrical surfaces, and non-metallic parts of aircraft, missiles, and satellites, as well as printed circuits, xerographic, conductive paper, and the like.
Since nano TiO 2 is an ultrafine powder, it must be fixed to a suitable carrier in an application. Glass, fiber, ceramic, plastic, paper, sand, and the like are used as the ultrafine TiO 2 carrier.
