1. What are the characteristics of environmentally friendly antibacterial coatings?
1, environmentally friendly antibacterial coating has no pollution to the environment. Environmental protection antibacterial coating has no pollution to the environment and is harmless to human body. Mainly because environmental protection antibacterial coatings are generally inorganic coatings, which are generally made of natural raw materials. Compared with traditional organic coatings, environmental protection antibacterial coatings have little or no pollution to the environment, whether in production or construction.
2. Environmental-friendly antibacterial coatings are beneficial to human health. There is a healthy functional environmental protection water-based paint in environmental protection antibacterial paint, which means that it will not produce pollution, but also has the characteristics of sterilization and deodorization, air purification and formaldehyde elimination, which can improve the living environment and be beneficial to human health.
3, the environment-friendly antibacterial coating is not easy to fade. The fading of paint has greatly affected the beauty of house decoration. Environmental protection antibacterial paint not only pays attention to the concept of environmental protection, but also pays special attention to colorfastness.
Second, the advantages and disadvantages of environmentally friendly antibacterial coatings
1, the advantages of environmentally friendly antibacterial coatings
Environmental protection antibacterial coating is more practical. Environmental protection antibacterial coatings are generally water-based coatings. The wall surface using water-based paint is generally bright and full in color, with excellent water resistance and impact resistance. The decorative effect is better than traditional paint, and it is non-toxic and tasteless, and does not contain harmful substances such as heavy metals, formaldehyde and benzene. Moreover, water-based paints generally have long service life and excellent anti-aging effect, and can be used indoors and outdoors.
Environmental protection antibacterial coating can prevent health problems caused by mold. Environmental protection antibacterial coatings are not easy to be corroded by bacteria, such as anti-mildew, anti-mildew and anti-corrosion coatings. Mold is considered as one of indoor air pollutants because of its pathogenicity to human body. Pathogens include active or dormant molds and their spores. The metabolites of mold during its growth and reproduction contain volatile organic compounds. The existence of a large number of molds not only makes people smell musty, but also makes people feel uncomfortable when they work with the corresponding molds, aggravating symptoms such as headache, eye and throat irritation, nausea, dizziness and fatigue. At present, many studies have revealed the relationship between asthma, allergic rhinitis and allergic pneumonia and some allergic reactions and molds in indoor air.
2. Disadvantages of environmentally friendly antibacterial coatings
Many environmentally friendly antibacterial coatings on the market are water-based coatings. Water-based paint requires high cleanliness of construction process and material surface. Because of the large surface tension of water, dirt is easy to shrink the coating and the dispersion stability against strong mechanical force is poor. When the flow velocity in the pipeline changes sharply, the dispersed particles are compressed into solid particles, resulting in pitting on the coating. It is required that the conveying pipeline has a good shape and the pipe wall is free of defects.
Environmental protection antibacterial coatings are green and healthy, and some environmental protection antibacterial coatings are beneficial to human body, which is a good coating, but most environmental protection antibacterial coatings are water-based coatings, which require high cleanliness of walls.
