Prepainted Steel Sheets - Anti Bacteria

 

Many places throughout society where cleanliness is key, such as hospitals, senior welfare facilities, public health facilities, restaurants, and public places, have recently fallen prey to environmental pollution. Unfortunately, the elderly, children, and the sick are becoming increasingly ill due to the emergence of staphylococcus aureus - a form of bacteria not affected by antibiotics. Our Anti Bacteria steel sheet is coated with paint containing an inorganic anti-bacterial agent. This specially treated paint bonds the ions of crystallized aminosilicate (an alkaline earth metal) and acts as a deodorant to polar substances, non-saturated carbons, and ion exchanges. It also has heat resistant and anti-decolorization properties. As long as this special paint remains on the steel sheet, it will always keep its anti-bacterial, deodorant, and fungus resistance properties.

Anti-bacterial properties

Staphylococcus aureus

This bacterium exists within human beings and animals living in a natural environment. This bacterium is categorized as either pathogenic or non-pathogenic. Forms of this coccus include otitis, mucous disease, and meningitis.

Colon bacillus

Sterilization against colon bacillus takes place at a boiling temperature of 60℃ for 15-20 minutes. Most forms of this bacterium are non-pathogenic and live inside the human body and organs of animals. Colon bacillus causes infections and diarrhea among newborn infants.

Pseudomonas aeruginosa

Pseudomonas aeruginosa is commonly found inside the intestine. This bacterium oxidizes and dissolves sugar, causing otitis, meningitis, and pneumonia among children. This bacterium widely exists in contaminated water and is highly resistant to antibiotics.

Bacillus subtilis

This bacterium generally does not grow in a normal environment, but will germinate rapidly as circumstances become more conducive to its growth.

Principle of Antibiosis & Applications      

Principle of Antibiosis

When coccus bacterium is absorbed on the surface of our specially coated steel sheet, the negative ion of the bacterium's cell membrane is absorbed by the positive ion of the anti-bacterial agent. As illustrated in the picture, the bacterial structure gradually weakens and then breaks, effectively eliminating it.

Applications

Drum of the washing machine

Anti-bacterial PE, PP resin

Kitchenware, chopping board (PE)

Kitchenware (PE container)

Anti-bacterial ABS resin

Durability and Tolerance Level

A test of Staphylococcus aureus and Pseudomonas aeruginosa was conducted to examine tolerance levels. Live bacteria was collected and re-measured in order to identify the tolerance of anti-bacteria in terms of MIC. Tolerance was not detected, indicating that the anti-bacterial properties of anti-bacterial steel sheet are semi-permanent.

Non-toxicity

Zeolite, which is used in anti-bacterial agents, is closely linked to our everyday lives, as it is used as an additive for animal feed and drying materials. Silver, which is added during the ion bonding process, has also been widely used since ancient times; it was used as a material for kitchenware, dental materials, ornaments, and disinfectants. In an experiment where radioactive silver was directly injected into the stomach, 99% of bacterium was discharged. No report has been made regarding safety concerns over the use of silver- zeolite (a composite of silver and zeol
