Nano titanium oxide and silicon oxide are used for anti -wrinkle fabric treatment

Nano oxides have many amazing properties and are widely used in the textile fields such as antibacterial, deodorizing, and anti -ultraviolet rays, etc functioned textiles. Similarly, nano oxide configuration has also had a positive impact. Add nano titanium dioxide or nano silicon oxide(sio2 hydrophobic or hydrophilic) to the traditional system, to form nano-oxide anti-wrinkle tidal liquids at high speed, and anti -wrinkle arrangement of fabrics.

 

Nano material is a new type of functional material that has a large surface area, many surface activity centers, and strong adsorption capacity. In recent years, the study of nano  titanium dioxide has been started in China. The addition of nano titanium dioxide effectively improves the anti -wrinkle effect of cotton fabrics, and at the same time greatly improves the strength of the fabric. When the content of nano -titanium dioxide is 0.1g/L, the anti -wrinkle performance and improvement of the fabric will be the best.

 

Real silk fabric has excellent hanging, soft luster, and special silk feeling, especially its good comfort and health effects. However, the silk fabric is easy to wrinkle when washing or wetting. In order to improve the rebound performance of real silk, many studies have been conducted at home and abroad. Studies have shown that nano -silicon oxide has many activity points , and its reaction activity is better than nano -titanium dioxide. On the surface of the experiment, the Malaysid Anid Anid anhydride anti -wrinkles can be used as a catalyst. In addition, the best process conditions for nano -silicon oxide as the anti -wrinkle system are: 2g/(50ml) of the Malay acid anhydride concentration, and the baking temperature of the roasting temperature It is 150C. This is realistic and economic value for improving the grade of textiles.

 

Apply unique function of nano powders to develop safe and efficient nano materials and used in textiles has great market prospects. The promotion and application of such technology is expected to give new economic growth points for textiles, medical and health materials, and health care products.

Application of TiO2 Nanotubes in Denitrification Field

TiO2 nanotubes have a high specific surface area (greater than 300m2/g). The specific surface area of ​​the catalyst has an important influence on the catalytic performance, so TiO2 nanotubes were used as the denitration catalyst carrier, and the manganese oxide/TiO2 nanotube denitration catalyst was prepared by loading manganese oxide by the equal impregnation method. The catalyst showed good low temperature denitration. performance, especially in the temperature range of 100-220 °C, the denitration activity is almost 100%.

Manganese oxide has relatively high catalytic activity in low-temperature denitration (electrons on 3D orbitals are very easy to migrate). Using TiO2 nanotubes with high specific surface as a carrier can improve the dispersion of manganese oxide and promote more catalytically active sites. At the same time, the mass transfer process of the reaction is improved; on the other hand, TiO2 nanotubes have strong anti-sulfur poisoning ability. In addition, the active sites of amorphous manganese oxide in the catalyst were uniformly dispersed on the surface of the carrier and the increase of Lewis acid content jointly promoted the improvement of catalyst performance.

The application of TiO2 nanotubes with large specific surface area in the catalytic reaction of low-temperature denitration is of great significance to expand the field of denitration.

Nano Silica Coating, Nano Titanium Dioxide Coating

Part of the bus use a transparent glass wall insulating glass coating, which is composed of nanoscale semiconductor material that allows interior cool. Such coatings and high-tech sound, that what constitutes nano-coating paint it? In general, the nano-coating must meet two conditions: First, the coating has at least one phase of the particle size range of 1-100 nanometers in diameter, and secondly, to make the presence of nano-coatings have significantly improved the performance or with new features.

Nano-silica coating: silica architectural coatings non-hierarchical, thixotropic, anti-sagging, good construction performance, and to a large extent improved the stain resistance, excellent self-cleaning properties and adhesion.Capable of forming a network structure of nano silica coating when dry, the coating can improve the degree of finish and aging vehicles, ships and vessels.

Nano-titanium dioxide coating: titanium dioxide paint architectural coatings can improve weatherproofing to a new level.The use of nano-titanium dioxide photocatalytic oxidation technology made the atmosphere purification paint, air purification effect of NO is good, but can also degrade other atmospheric pollutants such as halogenated hydrocarbons, sulfur compounds, aldehydes, polycyclic aromatic hydrocarbons .Nano-titanium dioxide photocatalytic composite application process is simple and low cost.

Nano calcium titanate coating: calcium titanate is an excellent filler and a white filler, with cheap, abundant resources, good color, high-grade characteristics.Research shows that nano calcium carbonate-filled paint, its flexibility, hardness, leveling and gloss have a more substantial increase.

Silver nano-titanium dioxide coating:Titanium dioxide under ultraviolet light is weak antibacterial effect is weak, you can indicate precious metal deposition to be modified in order to improve the photocatalytic bactericidal activity, and has excellent bactericidal properties of silver itself, will combine the two, makes titanium dioxide antibacterial performance pole greatly improved.By thermal deposition on the surface of titanium dioxide load a certain amount of silver can improve the photocatalytic antibacterial properties of the particles
