Antibacterial Ceramic

0,00 

Introduction

Ceramics due to having excellent chemical stability, as well as good appearance are widely used in different places such as hospitals and buildings. Ceramics, unfortunately, do not have antibacterial effect inherently, and the microorganisms reproduce easily on their surfaces, especially in wet environments. Regarding this, the need for frequent washing and the use of disinfectants is necessary. However, the use of these materials not only causes respiratory problems but also leads to the loss of cement and mortar between the ceramics. Therefore, the use of a ceramic which has inherent antibacterial properties can be effective in solving these problems. Zin oxide nanoparticles have antibacterial effect which can kill many types of bacteria. These nanoparticles penetrate into the cell walls of bacteria and microorganisms and prevent their growth and reproduction. These nanoparticles can be mixed with ceramic glaze as an additive.

The antibacterial nanoparticles prevent the growth of microorganisms which lead to contamination. The antibacterial nanoparticles prevent growth of microorganisms which give birth to spoilage and contamination. Zinc oxide nanoparticles show a strong antibacterial activity against the pathogenic bacteria such as E. coli and S. aureus. Addition of these kinds of nanoparticles to the waste bags can create antibacterial properties in them.

Antibacterial Machine-made Carpet

0,00 

Introduction

Carpet is a key decorative element which provides the principles of decoration via the use of color and texture. Recently, the carpet industry has lost market share because based on the findings, covering a floor with a carpet increases the illness, asthma and allergies. The use of soft floor coverings in schools, hospitals and other health care facilities has long been controversial as carpet is thought to contribute to the presence of microorganisms in the indoor environment. Indoor air is a complex mixture of bio-aerosols and non-biological particles. Among the most important of these are human and animal occupants that shed skin scales and other fragments, mold spores, viruses, and bacteria. Two types of antimicrobial treatments exist for carpets and coatings. The first type is used in the manufacturing process. The other type is an antimicrobial additive incorporated in a treatment of the carpet fibers during manufacturing.
