Description
Technical field
The present invention relates to artificial stone's technical fields, more particularly, to a kind of artificial porous volcanic rock slabstone and its system
Preparation Method.
Background technique
With the development of society, people have increasingly higher demands to the form of building or interior decoration.In metope
Perhaps floor decorative or the interior decoration watched for people are decorated, in order to embody different style, often uses day
Right granite, marble or ceramic tile are decorated.Using natural stone, resource is limited, higher cost, and processing is more difficult.
Therefore, more and more people are decorated using artificial stone, such as the artificial stone that artificial marble, microlite etc. are all types of.
For special porous stone, natural porous stone texture is numerous, different style, thus indoors decoration or other
In the ornament of same type, the use of porous stone is very extensive.But due to there are a large amount of holes so that bulk density it is relatively low,
Water absorption rate increases, intensity declines.Therefore, physical performance index is less than normal marble standard；Due to simultaneously, there is also big
The natural defects such as texture, shale line, shale band, the crackle of amount, so that the performance uniformity of this material is very poor.Such stone material category
In the limestone of carbonate structure, acid resistance is poor, and for the area of this kind of heavy contamination in Asia, acid-rain corrosion can be very serious,
It but will accelerate the destruction of stone material, so that the application of natural porous stone material is limited to.Since there are a series of for natural porous stone material
