Antibacterial flooring is the process of adding a certain amount of antibacterial agent to the flooring material. It can inhibit the growth of surface bacteria and achieve long-term health and safety.
Antibacterial agents can be divided into two major categories, organic and inorganic. At present, in the wood flooring market, products using inorganic antibacterial agents are more common. The inorganic antibacterial agent is further divided into three types: silver ion antibacterial agent, photocatalyst antibacterial agent and zinc oxide whisker. The first generation of antibacterial agent silver ions immobilize silver ions on the surface of porous materials by physical adsorption ion exchange, and react with bacteria in the air to form coagulated proteins, thereby destroying the proliferation of bacteria and even death. The advantage is that the effect is obvious, and an antibacterial reaction can occur in a normal state, but it is easily oxidized, resulting in an antibacterial effect not lasting. The second-generation antibacterial photocatalyst is mainly composed of nano-sized titanium dioxide, which absorbs light and is in a high-energy state, and transmits high energy to the reactants to cause chemical reaction to eliminate the floating bacteria, mold and dust in the air. The purpose of 螨. It is characterized by obvious effects, will not be oxidized, and lasting and stable, but it must be produced under the irradiation of ultraviolet rays to produce an antibacterial effect, and an antibacterial dead angle will be formed in places where sunlight is not irradiated. The third-generation antibacterial agent zinc oxide whisker can react with oxygen and moisture in the air to release various antibacterial substances such as oxygen atoms, hydroxyl radicals and negative oxygen ions. At the same time, zinc ions can also react with enzymes in bacteria to kill bacteria. It makes up for the shortcomings of the first two generations of antibacterial flooring, and the product has no obvious defects.
The antibacterial used by Green Shield is the third generation of antibacterial zinc oxide whiskers. Zinc oxide whiskers are a kind of semiconductor needle-shaped single crystal with adjustable internal carriers. The crystal has a considerable part of atomic oxygen, and atomic oxygen has strong oxidation activity, which can destroy the biological activity and metabolic reproduction function of bacteria. To achieve antibacterial purposes. After being combined with the plate, the zinc oxide whisker can also increase the wear resistance, toughening, shock absorption, noise reduction, absorbing, antistatic and other functional characteristics of the floor, and greatly improve the quality and grade of the wooden floor. According to the national authority inspection: the antibacterial rate of this floor is more than 99.99%; the flooding rate is over 95%; the mildew resistance level is 0.
