Abstract:
Our self-cleaning Nano coatings are a special Nano photocatalyst that combines photocatalyst actions with Nano technology.
Generally, detergents reduce the surface tension of water and the contact angle is lowered. When the surface of photocatalytic film is exposed to light, the contact angle of the photo catalyst surface with water is reduced gradually. Following sufficient exposure to light, the surface reaches a state of super-hydrophilicity. In other words, it does not repel water at all, so water cannot exist in the shape of a drop, but spreads flatly across the substrate. The hydrophilic nature of titanium dioxide, coupled with gravity, enable dust particles to be swept away by rain or wind, thus making the key feature of self-cleaning or easy-cleaning possible.

Nano Photocatalyst Coatings

Features of TiO2 Photocatalyst

Super Hydrophilicity

The photocatalyst coat will show the super hydrophilicity feature under light irradiation. The contact angle of the surface will be reduced to <10 degree, which brings 5 major benefits.

1. Water will not form a water-drop on the surface when its contact angle is <10°, it will form a complete thin water film. The water will take on a flat condition to the surface. This will help to reduce the water strain following rain wash.
2. Generally, cleaning agent reduces the contact angle of water on the surface, the so called hydrophilicity effect. Treated surfaces are keep clean and smart following rain or wind abrasion, the surface will be renew as if traditionally wash with a cleaning agent.
3. The hydrophilic feature helps to store water on the surface and thus the entire surface can be covered with much less water. This speeds up the process of transpiration. So if a building is externally coated, the building will need less energy to cool down in hot weather. If it is coated on the panel of a compressor within an air condition unit, the air condition system will show better efficiency.
4. Dust in the air becomes more difficult to absorb on super-hydrophilic surfaces.
5. The Hydrophilicity effect enables areas not hit by rain to becomes cleaner in times of rain & wind.

What's the difference between Photocatalyst & Non-photocatalyst coated surfaces?

When the coat is exposed to sunlight, it can decompose almost all the organic substance on the surface, which causes the following 2 benefits.
(In the presence of light, the Photo catalyst will decompose the organic pollutants. Without the adhesion of organic pollutant, the remaining inorganic pollutants on the surface are easily swept away.)
1. When the coat decomposes the absorbed organic pollutant on the surface (such as oil), it makes the surface cleaner. Once the oily substrate is decomposed, other inorganic pollutants are unlikely to stay on the surface, and can easily be washed away by rain, wind or other easy- cleaning method.
2. These coating can purify air quality. A positive side effect of Photocatalysis is that nitrogen oxide emissions generated by vehicles are purified. When roadside walls are coated, the surface becomes cleaner and the area around busy traffic zones are greatly enhanced environmentally.

Organic and inorganic pollutants are strongly adsorbed on the surface of walls that are photocatalystically coated.

Anti-bacterial and Anti-Mold Features

Major Benefits of Photocatalyst

1. The product can prevent the growth of mould, mildew or moss, so it will keep some marble, stone and granite building cleaner.
2. The antimicrobial action will not only destroy surface bacteria, but also kill bacteria in the air around the building surface, because of air flow and air pressure.
3. Anti-UV Feature. The product can absorb some UV and protect the surface. The UV light may make some coloured surfaces fade. The product can protect the surface from UV damage.
4. Antistatic Feature. The antistatic feature can resist the static adsorption of small dust particles such as ash, coal powder etc.

Tips: How to take advantage of the super-hydrophilic feature?

The super-hydrophilic feature can provide the same effect like detergent (reduce the contact angle of the surface).

Self-cleaning: If there is rain or wind, the Nano coating will provide a self-cleaning feature. The rain-wind abrasion on the surface has the same effect in time as if you clean with detergent.

Easy-cleaning: If there is no rain or wind abrasion, one simply needs to wash the surface using a little water. This will have the same effect to traditional washing with power-wash & detergent.

Next Generation Building Cleaning Solution
Objective
• Building self cleaning, protection and energy saving.
• Road self-cleaning, protection and car exhausts purification.
• Cleaner Cities & Motorways

Solution

The Nano photocatalyst coat is the combination of photocatalyst and Nano technology. By simply spraying the Nano coat on the building exterior surface one can bring diversified excellent features to the building. Also, the product can be sprayed on roads and roadsides to provide a self-cleaning & air purification function to highways. The Nano coat can keep the building or road in a renewed condition and reduce the costs of cleaning, environment protection and water.
Features:

• Super hydrophilicity
• Organic pollutant decomposition
• Anti-bacterial and anti-mold
• Anti-UV protection
• Surface antistatic
• Self-cleaning
• Easy-cleaning

Benefits:
• Keep the building in new and clean condition
• Protect the surface from dust, acid rain and air pollutant damage
• Purify the air pollutant near and on the surface (e.g. car exhausts
• NOx, Formaldehyde, Benzene, VOCs)
• Decompose the organic pollutant on the surface (e.g. oil, graffiti)
• Reduce the energy consumption for cooling the building in summer
• Restrain mildew or alga growing
• Kill the bacteria and virus on the surface and in the air near the coated building
• Absorb the UV from sun and then protect the surface from UV damage
• Restrain the dust electrostatic adsorption

NanoLandGlobal…..Our raison d'κtre

NanoLandGlobal are launching a NanoLand business entity in every country, with stakeholders created in US, Central America, Ireland, UK, Turkey, South Africa, Ghana, Baltic States, Serbia, Italy, Korea, China, India. We have requests pouring in from Canada, Mexico, Argentina, Brazil, France, Spain, Portugal, Hungary, Switzerland, Israel, GCC and the list is growing daily.

Our partner network will be offered the following services by us:
1. Access to unique range of smart fluid technology
2. Application Instructions & Training
3. New Products & Services
4. Health & Safety Information
5. Direct contact with Specialists
6. Business Leads and New Markets
7. Networking through Industry Alliance (GAINSS)
8. Trade Website & Information
9. Funding & Legal Advice services

NanoLandGlobal are a solution sales organisation, identifying areas of application for nanotechnology, matching solutions to problems, mainly for business stakeholders. We work with small, medium and large companies globally to fast track new technology, enhance efficiency, up productivity and innovation, whilst focusing on safety, Footprint, best practice environmentally and sustainability.

Needless to say, we are not just money motivated, but strive to introduce technologies that better humanity and Society. Thus safer agriculture, humane livestock and farming, improved industrial and commercial processes, cleaner supply-chains. Hence we look to increase food and industrial productivity deploying less resources, reduce wastage by better recycling, lower pollution, enhanced processes across every aspect of commerce, from light and energy efficiency to disease prevention and cleaner transport & construction.

By adopting safe Nano techniques, we eliminate risk around nanotechnology. We're not interested in messing with the building blocks of life, changing the essence of atoms and molecules! We deploy tools and expertise around nanotechnology that manipulate the Nano-scale, to understand the secrets of Nature herself, and thus drive innovation for today's companies for positive value. Hence we strive to create new solutions to reduce, for example, the menace of insect or rodent damage by using methods created by Nature over millennium.

We help forestry organisations protect young trees from damage, organic growers suffer less seed wastage, enhanced disease methodologies for livestock, improved air, nutrition for city dwellers and better food chain packaging and techniques with less cancer risk and less aggressive chemical usage for everyone. Companies that deploy cleaner and more efficient processes that look to better The Environment and Life generally for citizens are in alignment for future success and reward.

Our strategy at NLG is to dovetail the value of nanotechnology generally, with environmental and sustainable best practice, business process efficiency and energy enhancement.
