Embodiment Construction

[0027] The semiconductor material nano-powder is loaded on the carrier with strong adsorption capacity by mechanical spraying method, or the nano-powder is mixed with the carrier with strong adsorption capacity. Nano powder refers to nano zinc oxide ZnO, nano titanium oxide TiO 2 , nano cadmium sulfide CdS, nano tungsten oxide WO 3 , Nano-Fe2O3 2 o 3 , Nano lead sulfate PbS, Nano tin oxide SnO 2 , nano zinc sulfide ZnS, nano strontium titanate SrTiO 3 Or nano silicon oxide SiO 2 Wait. The carrier is composed of triethanolamine and sodium metaphosphate, wherein sodium metaphosphate can also be replaced by polyvinyl butyl ether or dodecylamine (triethanolamine cannot be replaced). The following nano-powder is divided into eleven groups by taking nano-zinc oxide ZnO, carrier triethanolamine and sodium metaphosphate as examples:

Abstract

The invention relates to nano-photocatalysis air rectification spray technology. At present, the environment in the car and room commonly has serious problems that is the longterm existence of the harmful gas such as formaldehyde, benzene, toluene, xylene and so on, harmful to the health of human. The purpose of the invention is to develop a nano-catalysis air rectification spray technology. The technical proposal of the invention is to: quantificationally withdraw deionized water, fill into the reaction kettle to react, put in triethanolamine and sodium metaphosphate at the same time, mix round and melt, raise the stirring rate of the reaction kettle to the maximum, add nano-powder, keeping stir for 3-5 hours to get the white suspended etching solution. The use is to contact the nano-zinc oxide with the air under natural light to produce much of anion like supperoxide anion and hydroxyl free radical, which can rapidly and fully degrade the harmful gas like formaldehyde, raise the air quality indoor rapidly, and raise the security indoor and the human health all the better.

Description

1. Technical field [0001] The invention relates to a nano-photocatalytic air-purifying spray technology, which uses nano-zinc oxide to contact air under natural light to immediately generate a large amount of negative ions such as superoxide negative ions and hydroxyl radicals, and is mainly used to improve indoor air quality, which is safe and healthy. 2. Background technology [0002] At present, in real life, there are generally serious problems in the indoor environment. There may be harmful gases such as formaldehyde, benzene, toluene, xylene, etc. in cars, various indoor decorative panels, and furniture. Extremely detrimental to human health. In order to purify the air and improve people's quality of life and health, in the patent disclosure of the State Intellectual Property Office, the published application number on May 28, 2003 is 01134887.9, and the name is a patent application for an air purifier. The publication number is CN1420317, and its technology It includ...
