Description
Technical field
The invention discloses a kind of modification infusorial earth Quito functional architecture plate, belong to building material technical field.
Background technology
With the increasingly raising of modern social economy technical merit, security of the numerous residents in town and country to indoor living environment
Increasingly pay attention to comfort, dry and wet is uncomfortable, formaldehyde pollution, PM2.5, air conditioner disease etc. are talked about as the hot spot of public attention already
Therefore topic, also becomes research using the environment adjustment type porous material that the strong absorbent media such as diatomite, activated carbon is function ingredients
One of hot spot.
Diatomite is to be carried under effect of natural environment after the unicellular Diatomeae biological death of time immemorial extreme enrichment, is heavy
The weak rock that product, mineralising are formed, has flourishing and regular pore structure, its adsorption capacity is strong, chemical property
It is relatively stable, traditionally it is mainly used as catalyst carrier, filter aid, decolorising agent, light filler, mild abrasives etc..In recent years, it is all
More researchs demonstrate positive contribution of the diatomite to amenity and security, as Chen Zuoyi, Kong Wei, Liu Chenglou, Wang,
Vu, Song etc. have studied diatomite or the humidity of its composite granule；Cheng Lun, Wang Jiao, Gao Ruqin, Zhang Rui, Im etc. are inquired into
The formaldehyde absorbing ability of diatomite and its derived material；Wang Chun, Gao Ruqin, Da, Davraz, Posi, Sari, Tan etc. are discussed
Thermal and insulating performance of diatomaceous construction material etc..The studies above lays particular emphasis on the performance research and development of diatomite fine ore, market mostly
On diatom building material product be also mainly limited to diatom ooze, diatom coating etc. a few.Since 2010, Tong Yu etc. passes through water
Diatomite conversion is solidified into kind of light building board, the particularly mechanical strength and heat conductivility to diatom plate by thermal reaction process
Etc. having carried out careful discussion.But at present traditional diatomite building panel also there are mechanical property it is bad the problem of, therefore also need
This is studied.
The content of the invention
The present invention solves the technical problem of：For traditional diatomite building panel mechanical property it is bad the problem of, carry
