Embodiment

[0037] The present invention adopts light-excited high-activity multi-dimensional structure nano-ceramic sheet, 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 solidify 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 photoexcited high-activity multi-dimensional structure nano-ceramic sheet, which is characterized in that: the raw material formula: the raw materials are taken according to the percentage by mass: industrial waste 30-80%, mineral raw materials 5-30%, kaolin 10-50%, and The percentages of chemical components are: silicon dioxide 60-80%, aluminum oxide 8-20%, calcium oxide 0.5-3%, magnesium oxide 1-3%; the preparation of light-excited high-activity multi-dimensional structure nano-ceramic sheet adopts: The process steps of mixing pulping→skeleton molding→setting and drying→high temperature firing→catalytic liquid spraying→fixed temperature drying→product inspection→packing and leaving the factory. The invention can effectively decompose almost all gas pollutants of TVOC and VOC, can quickly decompose the pollutants into non-toxic clean gas, and can effectively avoid the secondary pollution problem of using filter consumables, purify the air in the polluted environment, discharge and remove VOC up to the standard PM2.5 has unparalleled ability to pollute and kill bacteria and viruses.

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...
