Embodiment

[0037] The present invention adopts light-excited high-activity multi-dimensional structure nano-ceramic sheet, and under the light excitation, electrons in the valence band are excited to the conduction band to form electrons and holes, which interact with O2 and H2O adsorbed on the surface to generate superoxide anion radicals, O2 -Hydroxyl radical-OH, its free radicals have a strong ability to oxidize and decompose, and can destroy C-C bonds, C-H bonds, O-H bonds, and N-H bonds in organic matter, and decompose organic matter into carbon dioxide and water; at the same time, it can destroy the cell membrane of bacteria and cure the virus Proteins change the living environment of bacteria and viruses to kill bacteria and viruses. Since the material converts light energy into chemical energy, the material itself does not participate in the reaction, so there is no consumption.

Abstract

The invention relates to a light-activated high-activity nanometer ceramic chip with a multidimensional structure, which is characterized by being prepared from the following raw materials in percentage by weight according to a raw material formula: 30-80% of industrial waste, 5-30% of mineral raw material and 10-50% of kaolin, wherein the percentages of the chemical components of the kaolin are as follows: 60-80% of silica, 8-20% of aluminum oxide, 0.5-3% of calcium oxide and 1-3% of magnesium oxide; the light-activated high-activity nanometer ceramic chip with the multidimensional structure is prepared by processing steps of mixing and pulping, skeleton forming, shaping and drying, high temperature firing, catalytic liquid spray brushing, constant temperature drying, product checking and packaging and leaving factory. The light-activated high-activity nanometer ceramic chip provided by the invention can effectively decompose nearly all gas pollutants of TVOC (total volatile organic compound) and VOC (volatile organic compound), quickly decompose the pollutants into harmless and clean gases, effectively avoid the secondary pollution problem resulting from the use of filter consumables, purify the environmental pollution gases, meet the VOC emission standard, remove PM2.5 pollution and kill bacteria and viruses, thereby having incomparable ability.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection and building materials, and in particular relates to a photo-excited high-activity multi-dimensional structure nano-ceramic sheet and a preparation method thereof. Background technique [0002] At present, in the existing technology, gas pollution, especially TVOC and VOC gas pollution, is traditionally solved by replacing filter consumables or surface spraying. There are: short service life, easy to produce secondary pollution, and environmental protection of polluted consumables Disposal and other issues, more importantly, can not fundamentally eliminate pollution. Contents of the invention [0003] The present invention overcomes the above-mentioned defects, and aims to solve the problem of effectively decomposing TVOC and VOC gas pollutants, decomposing pollutants into non-toxic clean gases, and avoiding secondary pollution by using filter consumables. Inspire highly activ...
