The term "nano" is circulating in the world, but it originally refers to a unit meaning "one billionth." Therefore, adding "nano" to units like meters, seconds, liters, or grams indicates one billionth of those units, but for some reason, only the length unit with "nano" after "m" is receiving the spotlight. 1 nanometer, commonly referred to as "1 nano," simply means one billionth of a meter. In this document, we will provide specific examples to explain its meaning.

We would like to introduce a case where our company proposed photocatalysts for indoor deodorization. In the past, during tenant turnover, we have been replacing wallpaper and vinyl CF sheets on the floors as part of renovations and conducting cleaning. However, there are instances where lingering odors from daily life remain, making deodorization challenging. We received inquiries asking if there are methods to eliminate such room odors. As a cost-effective solution, we proposed three methods: "applying photocatalysts not only to walls and floors but also to fabrics," "applying dark area photocatalysts in places that do not receive light," and "occasionally humidifying the space." [Case Overview] ■ Issues - There are instances where lingering odors from daily life remain, making deodorization difficult. - The types of odors primarily include musty smells, odors from foreign dietary habits of residents, tobacco smells, and perfume scents from women. ■ Proposal - Apply photocatalysts not only to walls and floors but also to fabrics like curtains. - Apply dark area photocatalysts in places that do not receive light, such as inside closets, under the kitchen, and behind toilets. - Occasionally humidify the space. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Points to Note on the Photocatalytic Self-Cleaning Function" of Chemical Technology Co., Ltd. The self-cleaning function of the photocatalyst depends on hydrophilicity. It only refers to the anti-fouling function against hydrophobic contaminants. When water is sprayed onto the photocatalytic surface with a mist sprayer, a water film spreads, confirming good hydrophilicity, which is a characteristic of the photocatalyst. [Features] ■ The self-cleaning function of the photocatalyst depends on hydrophilicity ■ It only refers to the anti-fouling function against hydrophobic contaminants ■ When water is sprayed with a mist sprayer, a water film spreads, confirming good hydrophilicity ■ The self-cleaning effect is strictly proportional to hydrophilicity *For more details, please refer to the PDF document or feel free to contact us.

The deodorizing function of photocatalysts is almost proportional to the surface area, so applying them to materials with a larger surface area will increase their effectiveness. For example, smooth glass has a surface area of 1.3 m²/g, but even nylon, which has the smallest surface area, has an effective surface area more than ten times that. To achieve a noticeable deodorizing effect, it is recommended to apply "NFE2" to fibers with as large a surface area as possible. 【Application to Fibers】 ＜Type of Fiber: BET Adsorption Surface Area cm²/g＞ ■ Wool: 400–600 ■ Cotton: 60–120 ■ Polyester: 20–50 ■ Nylon: 15–50 ■ Glass t=3.0mm (for reference): 1.3 *For more details, please refer to the PDF document or feel free to contact us.

Here are the capabilities that can only be realized with the photocatalyst "NFE2." It has a high and guaranteed safety against mold and algae, and its self-cleaning effect is excellent not only for exteriors but also for interiors. It boasts high water resistance that can be applied even underwater, and it allows for low-temperature, short-time baking processes. Thanks to the product's super hydrophilicity, high antibacterial properties, affinity with the substrate at high temperatures, and active oxygen retention performance, it enables the creation of "anti-mold and anti-virus air conditioner filters," "algae-free aquariums," "curtains that instantly eliminate odors," and "stain-resistant exterior baked panels." This is an additional feature that we highly recommend for those struggling with differentiating their own products. 【Capabilities】 ■ Anti-mold and anti-virus air conditioner filters ■ Algae-free aquariums ■ Curtains that instantly eliminate odors ■ Stain-resistant exterior baked panels ■ Costumes that do not retain sweat odor ■ Mouse and mouse pads that do not get fingerprints *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our tangible photocatalyst product, the "Photocatalytic Deodorizing Mat for Refrigerators." There have been questions such as, "Isn't it meaningless for a photocatalyst since the light goes off when the refrigerator door is closed?" but there is no need to worry. This deodorizing mat does not need to be constantly illuminated; a sunbath about once a month is sufficient to maintain its performance. It can be said that this product fundamentally overturns the preconceived notion that "photocatalysts need constant light, especially for indoor use." 【Features】 ■ No need for constant illumination ■ Activated sufficiently with about 30 minutes of sunlight during clear weather once a month ■ Activating it with a mist sprayer or similar during sunbathing significantly enhances its effectiveness ■ Remarkably eliminates unpleasant odors from the refrigerator ■ The deodorizing mat can be used repeatedly and semi-permanently *For more details, please refer to the PDF document or feel free to contact us.
