Antibacterial material composition and effects of the different. With antibacterial horizontal fencing with composite decking flooring, the antibacterial ingredient are not the same. Generally classified antibacterial agents can be divided into organic and inorganic two categories, currently in colored composite deck tiles wood flooring market, the use of inorganic antimicrobial agent products were more common. The inorganic antimicrobial agent is divided into silver ion antimicrobial agents, photocatalytic antibacterial agent and zinc oxide whisker three.
Silver ion antimicrobial agents: The use of antibacterial silver by physical adsorption and ion exchange method, the silver ions fixed on the surface of a porous material such as zeolite; silver ion antimicrobial capability is contact, and no contact is almost no antimicrobial activity.
Photocatalyst antibacterial agent: The main ingredient is nano-titanium dioxide by absorbing light in a high energy state, and passes to high-energy reaction was to make a chemical reaction, played eliminate air planktonic bacteria, mold, dust mites purposes ; the role of photocatalyst antibacterial process needs light in a dark environment, antibacterial activity will be reduced.
Zinc oxide whisker: Must be releasing oxygen atoms and oxygen in the air react with water under normal conditions, the hydroxyl radical, negative oxygen ions and other antimicrobial substances. Meanwhile, the zinc ions can react with the bacterial enzymes to kill bacteria; zinc oxide whisker antibacterial activity related to the content of moisture in the air, in a relatively dry environment antibacterial activity will be reduced.
