Description
Technical field
The invention discloses a kind of preparation method of the special diatom ooze of wall, belong to building material technical field.
Background technology
With the development of science and technology, people are to the comfort level of living environment and the requirement more and more higher of aesthetic property, wherein, comfortably
One major influence factors of degree are indoor humidity.When humidity is too high, uncomfortable in chest, unsmooth breath etc. may result in, and humidity
When too low, people can feel very dry again.Although have the plant equipment such as air-conditioning, humidifier at present to adjust indoor comfortable
Degree, but the use of these plant equipment needs to consume the substantial amounts of energy, causes the pollution of environment to a certain extent.Diatom ooze
It is a kind of ornament materials being made up of inorganic coagulation material, diatom functional stuffing, color stuffing and other auxiliary materials, its own tool
The decoration performance of standby coating.And after diatomite is a kind of unicellular alga death of individual very little, its remains is in ocean or lake
It is middle deposition and formed.Diatomite is mixed with other materials to prepare and a kind of both can adjust indoor humidity and itself is free of
There is the ornament materials of harmful substance, there is wide market application and promotion prospect.
Diatom ooze is used as wall surface decoration wall material health environment-friendly superior performance, and now, wall surfacing material commercially uses
Relatively broad has wallpaper class, coating class, ceramic-like, category of glass, in addition, there is some metal classes.And diatom ooze is as a kind of
Integrate new indoor wall surfacing material of the performance with environmental protection as the whole body, be but rarely employed, but with popularization in recent years, diatom ooze
Finishing material is just slowly known, becomes the new lover of interior decoration circle.At present, because the time of diatom ooze introducing is just short
Short more than ten years, its development are not also very perfect, and many people new decoration wall material this to diatom ooze is right nor be well aware of
The property indices of diatom ooze are even more known very few, and the diatom ooze of in the market is also that the good and bad jumbled together, and the diatom ooze industry good and the bad is not
Together, some false diatom oozes, which can meet water, can be reduced into mud, and its being firmly bonded property is there is serious quality problems, and it comes off
The silica in diatom ooze dust afterwards largely suspends in atmosphere, sucks this suspended material for a long time, easily makes one to suffer from
Anthraco-silicosis, healthy hidden danger is brought, therefore also need to study diatom ooze.
