Natural Slate is a plate structure, the basic rock is not recrystallized, is a metamorphic rock, original rock to mud, silty or neutral tuff, management direction along the plate can peel into thin slices.The color of slate with the impurities they contain varies
Slate
With iron for the red or yellow ; containing carbon quality for the black or gray ; with calcium in the case of hydrochloric acid will bubble, so named for the color of its general classification, as will the green slate, black slate, calcareous slate.
Slate can be used as building materials and decoration materials, in ancient times used to do in areas rich in slate tiles.Slate generally do not contain minerals .
One explanation
A shallow rocks.By the sticky soil quality, silt , or in the acidic quality of tuffaceous sedimentary rocks, tuff has been slightly metamorphic formation.Black or dark gray.Lithology dense, tabular cleavage development.The plate is often a small amount of sericite and other minerals, so that board was silk micro-gloss.No obvious recrystallization phenomenon.Microscope can be seen under a number of uneven distribution of quartz , sericite, chlorite and other mineral grains , but most of aphanitic of clay minerals and carbon, iron powder.With variable structure and spot-like structure over.Common types of carbonaceous slate, calcareous slate, black slate; also be based on the rock of the other features, such as mineral composition, texture and structure, etc., into an empty slate spar, dot-like slate, silty board rock, silicon slate.Slate widely distributed in the regional low-temperature dynamic metamorphism of the rocks, such as northern China early Proterozoic Hutuo group of beans village slate, the South in the late Proterozoic of Banxi Group , Kunyang group so there is also a large number of distribution.Can be used for building stone.
Explain the two
With tectonic plate rock is slate too.The original rocks are mainly mudstone , muddy siltstone and acid tuff.Recrystallization was not obvious, microscope, and some are muddy sericite, chlorite, silica, and sometimes have to see a small amount of muscovite , biotite and quartz.More than mud with variable structure.Slate is the regional metamorphism was low-level product, temperature and pressure are not to high, mainly due to stress effects.
Explained the three
The muddy and silty component-based development of cleavage plate metamorphic rocks.Original rock composition of clay rocks , siltstone , or in the acidic tuff , powered by the regional low-temperature metamorphism.Slate to mineral particles or aphanitic main recrystallization is not developed, with significant changes over the structure and construction.According to the rock composition and color impurities, can be divided into carbonaceous slate, calcareous slate, sandy slate, spotted slate and other subgroups.Compact structure, board management and development of building stone and slate to do the monument , Yan and other stone.
Over the years, many facts prove that natural stone has become one of the most popular flooring materials.They have some potential Slate In the feature, very suitable for bathroom flooring.Slate, as a natural stone, its inherent characteristics make it ideal for bathroom flooring, the advantages are the following:
Aesthetic value: the popularity of slate in the home, including indoor and outdoor largely due to the aesthetic value of the slate.Its unique surface provides a rich variety of designs and colors, all of which are natural heaven's.Between the brick and tile vary, which makes the bathroom to become unique.However, different color and design but will not lead to inconsistent patterns.In fact, this will only add to the beauty of slate tiles, because they bring to the people is a different feeling, which is beyond the reach of other floor tiles, even the same as natural stone tiles.
Durable: The reason that the slate tile is an ideal material for bathroom Another major advantage is that it is very wearable.This is also a lot of people in high traffic areas proposed to install slate flooring reasons.In some cases, some owners complain about will appear on the slate floor, "traffic map", which led to frequent flow of people walking around wearing the formation of potholes slate.This is not true.Must be pointed out is caused by the "traffic map" because the slate tiles on a regular basis for the conservation agent.Floor tiles need to know this special care, to be used by the record in order to understand what type of curing agent which is compatible with.
Slip: If you choose the stone surface is correct, then the natural slate tile slip resistance can be maintained.Otherwise it is dangerous when wet.Nevertheless, the slate tile slip resistance depends mainly on its uneven surface.
If conservation is not sufficient, slate tiles fade easily.The penetration of large amounts of water will lead to the appearance of old slate tiles.Therefore, the slate is best not to install in wet areas in the long term, in some places, such as shower areas or regularly use other materials instead of curing agent with the correct maintenance.
Of course, the slate tiles are not perfect, no flaws.As time passes, they will be cracks.However, slate bathroom flooring bathroom flooring industry is the most sought-after material.
