Indoor environment quality and the choice of green building materials

1. Development of green building materials

Green building materials, also known as ecological building materials, environmental protection building materials, and healthy building materials, are non-toxic, non-polluting, non-radioactive, and environmentally friendly. They are produced using clean production technology, using less natural resources and energy, and using large amounts of industrial or urban solid waste. And human health building materials. To improve the quality of the indoor environment, the use of green building materials is the core of preventing indoor air pollution.

In recent years, some green building products that are ecologically friendly have been developed at home and abroad, such as non-toxic coatings, antibacterial coatings, photochromic glass, humidity-controlling building materials, ecological architectural coatings, plastic paint decoration materials, ecological flooring, and gypsum decorative materials. , clean air prefabricated panels, antibacterial ceramics, nano air purification anion coating, and more. In the selection of construction and decoration materials, these low-emission, low-pollution, green building materials should be used as much as possible, and consideration should be given to using more renewable building materials. On the one hand, indoor environmental pollution and waste of raw materials can be avoided. On the other hand, Shanghai Decoration Company's green building materials can meet the needs of sustainable development, achieve the unification of development and the environment, combine modern and long-term, promote the development of green building materials, and build green, safe, comfortable and beautiful buildings with green building materials. Architecture and indoor environment.

2, nano air purification coating

(1) Characteristics of nano-air purification coating The nano-air purification coating is based on nano-photocatalytic materials to purify the air. It is a new type of environmental protection material. The main features are: dual-function, high efficiency. Dual function means that the nano air purification coating can purify the air while at the same time it can induce a large number of negative ions and make the breathing smooth. The high efficiency is that using nano air to purify the coating can significantly reduce indoor formaldehyde and harmful substances in the air.
(2) Engineering application of nano-air purification coating directly on the indoor wall, or with a 0.3-0.5mm caliber spray gun, the reaction of the material generated after the event of light can decompose formaldehyde into water and carbon dioxide, while also lasting release A large number of negative ions, sterilization, disinfection, deodorization, degradation of odor, no secondary pollution, and the price is not high, the average cost per square meter is about 3 yuan.
(3) The scope of application is applicable to interior walls such as offices, conference rooms, living rooms, hotels, restaurants, classrooms, waiting rooms, hospital wards, engine compartments, carriages, cabins, factories, and all public places.
