Who can introduce the knowledge about marble ah?

Marble due to different chemical compositions, even the same grade, the difference in gloss can be very large. Of course the same

a material between different grades of the surface gloss of the plate will also have some differences. In addition, the strength of the marble plate,

Water absorption rate is also an important indicator to evaluate the quality of marble.

Marble stone characteristics and and advantages:

1.

No deformation, high hardness, wear resistance.

2.

Anti-abrasive, high temperature resistance, maintenance-free.

3.

Maintenance of marble

Marble is easily stained, cleaning should be done with less water, wiping regularly with a slightly damp cloth with mild detergent, and then

drying and polishing with a clean soft cloth. Heavily abraded marble furniture that is difficult to handle can be wiped down with steel wool, then

polished with an electric grinder to bring back its luster. Or scrub carefully with a liquid scrubber, use lemon juice or vinegar to clean

stains, but it's best to leave the lemon on for no more than

2

minutes, repeating the operation if necessary, then rinse and

dry. For minor abrasions, use specialized marble cleaners and conditioners. For antique or valuable marble

furniture should be handled by a professional.

Cultural stone

Cultural stone has artificial and natural two kinds, its material is hard, bright color, rich texture, different styles, but not

enough flat, generally used for outdoor or indoor local decoration:

1.

Natural cultural stone

Natural cultural stone is mined in the natural world of the stone mine booking, which the slate, Sandstone, quartzite, after processing,

become a decorative building materials. Natural culture stone material hard, bright color, rich texture, different styles, with

pressure, wear-resistant

, fire-resistant, cold-resistant, corrosion-resistant, low water absorption rate and other characteristics.

2.

Artificial culture stone

Artificial culture stone is refined using calcium silicate, gypsum and other materials. It imitates the appearance of natural stone texture,

has the characteristics of light texture, colorful, non-moldy, non-combustible, easy to install.

Culture stone itself does not have a specific cultural connotation. But culture stone has a rough texture, natural form,

It can be said that the culture stone is a return to nature, back to simplicity in the interior decoration of a reflection of the state of mind. This mentality

We can also be understood as a culture of life. Natural culture stone is mined in the natural stone deposits, its

slate, sandstone, quartzite, after processing, become a decorative building materials. Natural culture stone material is hard, color

sharp, rich texture, different styles. It has the advantages of pressure resistance, abrasion resistance, fire resistance, cold resistance, corrosion resistance, low water absorption rate, etc.

Advantages.

The most important feature of natural culture stone is durable, not afraid of dirty, can be unlimited scrubbing. But the decorative effect by the stone

The original texture of the material limitations, in addition to the square stone, the other construction is more difficult, as if the splicing.

A, granite

Granite is a volcanic eruption of lava and by considerable pressure in the molten state uplifted to the surface of the crust

of the tectonic rock. In the formation of the crustal surface, it moves slowly and cools down. It is a type of

igneous rock

, which is a material formed

by the cooling and solidifying

crystallization

of magma or lava containing

silicate

melt.

When molten

magma condenses and solidifies, minerals are formed in igneous rocks, like olivine and pyroxene. The densest iron-magnesium-silicate

minerals form when the magma is at its highest temperature; less dense minerals, such as feldspars and quartz, form later in the cooling

period. Minerals that form in lava can usually grow uninhibitedly and have well-developed crystal forms. To quote

Using information from

China Instrument Superstore

(

www.cimart.com.cn

), granite is a granular crystalline rock, with alkali feldspars and quartz as the main

constituent ores. Usually more feldspar than quartz, the two into the interlocking organization of the production of the following three

classes:

(1)

different components of alkali feldspar alone,

(2)

different alkali feldspar with homomorphic analogues into a solid fusion or bicrystalline

shaped intergrowths,

(3)

and Calcium feldspar into solid melts resulting in aggregated sheet bicrystalline intergrowths, but of which

80-85%

is sodium feldspar.

Alkali

Feldspar

in petrology refers to orthoclase feldspar, microplagioclase feldspar, sodium feldspar, and omphacite or a combination of these feldspars into a solid fusion, with omphacite containing a molecular percentage of sodium feldspar of no less than

80%

. Potassium feldspar

(

orthoclase or microplagioclase feldspar molecules

)

, and sodium feldspar molecular

formulas are denoted by

K(Al Si3O8)

and

Na(Al Si3O8)

, respectively. The molecular formula of calcium feldspar is

CaAl2 Si3O8

. Calcium feldspar

and sodium feldspar components can form solid fusions in various ratios,

known in mineralogy as plagioclase feldspar minerals or

calcium

~

sodium feldspars.

Commercial granites include the aforementioned granites, gneisses, gneisses, granite gneisses, and what scholars

call orthoclase, granodiorite, and granitic amphibolites with compositions intermediate between them. Gneisses include rocks with mineral compositions that resemble

granite and with granular crystalline organization. Commercial granite also includes other similarly organized feldspathic crystalline rocks with a few minor subcomponent

minerals, mainly decorative, such as calcium plagioclase, as it is known to petrologists. Gneiss is a crystalline rock with coarse

texture, mainly composed of silicate minerals, mosaic and granular crystalline organization, different types of minerals

regularly or irregularly, and caused by the interactive arrangement. According to the American Society for Testing and Materials (ASTM), granite is categorized into ordinary

granite and black granite. Ordinary granite consists of

quartz

,

feldspar

,

mica

, etc., and because of the colored minerals, it has

black or dark green, and feldspar is often responsible for its overall color. Black granite dark green or black rock, by

plagioclase feldspar, pyroxene,

olivine

, hornblende and other rock-forming, so the black granite is divided into three kinds of porphyritic rocks, pyroxene, basalt

wulfenite and so on.

A deep acidic igneous rock, belonging to the magmatic rocks. Commonly known as granite. Silicon dioxide content is mostly in

70

% or more

. Blocky unstratified, granite mosaic structure, often through the ball weathering. The color is lighter, with off-white and flesh-red more

common. It is mainly composed of quartz

(

) and a small amount of dark minerals such as black mica (hardness

2-4

) and other dark minerals grouped

into it. The quartz content is

20

% to

40

%, and alkali feldspar is more than plagioclase feldspar, accounting for about

2

3

or more of the total amount of feldspar. The alkali

feldspars are various potassium and sodium feldspars, and the plagioclase feldspars are mainly sodium more feldspars or more feldspars. The dark minerals are dominated by black mica

, with small amounts of hornblende. With granular structure or seemingly patchy structure. According to the type of minerals contained, it can be divided into black granite

rock (see:

www.xuechisc.com

), leucogranite granite, hornblende granite, diamictite granite, etc.

By the structural structure, it can be divided into fine-grained granite, medium-grained granite, coarse-grained granite,

patchy granite

, seemingly porphyritic granite

granite, crystal hole granite and gneiss granite, etc.; according to the contained secondary minerals, can be divided into cassiterite granite, niobium-iron

mineral granite, beryllium-containing granite, lithium mica granite,

tourmaline

granite, etc.. Autometamorphism such as feldspathization, dunite petrogenesis, and

tourmaline petrogenesis are common. Granite is a widely distributed rock that has been produced in all geologic ages. Forms

The form is mostly rocky base, rocky strain, rocky bell and so on. In terms of genesis, some people believe that granite is deep in the crust of the granite plasma by

condensation crystallization or by basaltic plasma crystallization

crystalline differentiation into, and some people believe that it is the depth of metamorphism and account for the role of granitization caused by the result of granitization.

1000-3000

kg/cm. Granite is not easy to weather, beautiful color, the appearance of the color can be maintained for more than a century, by

in addition to its high hardness, wear-resistant, in addition to being used for high-level architectural decoration works, hall floor, or open-air carving of the first

choice of material.

Second, the resource situation

Granite rocks in China accounted for about

% of the national territory, amounting to

80

More than 80

million square kilometers, especially in the southeast region,

Large areas of exposed all kinds of granite bodies,

See the large amount of its reserves.

According to incomplete statistics,

there are about

300

multiple kinds of granite rocks.

The better ones are listed as follows:

Three, evaluation methods

Processed finished veneer stone, the quality of its good or bad can be identified from the following four aspects:

One view, that is, the naked eye to observe the surface structure of the stone. Generally speaking, the uniform fine material structure of the stone has a delicate

texture,

for the stone of the best;

coarse and unequal grain structure of the stone its appearance is poor,

mechanical properties are not uniform,

slightly poorer quality. In addition to natural stone due to the effect of geological action, often in which some of the fine veins and microfissures,

Stone is most likely to rupture along these parts, should be noted that the culling. As for the lack of corners is to affect the aesthetics, choose especially

should pay attention to.

Two measurements, that is, the measurement of stone size specifications. So as not to affect the splicing or cause splicing patterns, patterns, lines change

shaped, affecting the decorative effect.

Three listen, that is, listen to the stone knocking sound. Generally speaking good quality, dense and uniform internal and no micro-fracture

Stone, its knocking sound crisp and pleasant; on the contrary, if there is a micro-fracture or vein inside the stone, or due to weathering lead to particles

contact between the loosening of the knocking sound coarse and hoarse.

Four test, that is, a simple test method to test the quality of the stone. Usually on the back of the stone on a small drop of

ink

, such as ink quickly dispersed around the leaching, that is, the stone internal particles loose or the existence of microscopic fissures, stone

quantity is not good; on the contrary, it is a dense stone, good texture.

In the selection of finished panels, because the stone raw materials are natural, it is impossible to texture identical, in the mining plus

The level of craftsmanship in the work there are also differences. Most of the stone is divided into grades. Granite stone has no colored stripes, most

number only colored spots, there are also solid colors. The finer the mineral particles in it, the better.

It serves to sharpen knives

.

Artificial stone: artificial stone is made from unnatural mixtures, such as resin, cement plus crushed stone binder.

Artificial stone is a general term for artificial marble and artificial onyx.

It is made from unsaturated polyester resin mixed with fillers and

pigments,

adding a small amount of initiator, and made by certain processing procedures. In the manufacturing process with different colorants can be made with

colorful, glossy jade like natural marble products.

Artificial stone products are easy to manufacture,

short production cycle,

low cost,

widely used in a variety of indoor and outdoor building decoration.

Artificial stone

30

years ago in the United States,

China's earliest application of artificial stone products as a decorative material is

90

90

s mid

some of the coastal developed cities, a few years after the widespread popularity. Now the craze is spreading to small and medium-sized cities on the mainland.

This product has the following characteristics:

1.

What is the main difference between artificial stone and natural marble?

Artificial stone has non-toxic, non-penetrating, easy to cut and process, the color can be arbitrarily deployed, the shape of any casting, can be spliced

Join a variety of shapes and patterns, and can be cast with a sink, splicing does not leave traces of the advantages of the natural marble in addition to the hardness

higher than artificial stone,

Other aspects can not be compared with artificial stone,

Some natural marble also has radioactive properties, and the natural marble can be used to produce a variety of natural marbles, including artificial stone. Some natural marble also has radioactive substances,

harmful to the human body.

What are the main uses of artificial stone products?

Artificial stone can be done in addition to high-grade cooking countertops, window sills, bathtubs, pedestal basins, building columns, high-level leisure table

Outside of the casting of a variety of sculpture decorations, I believe that in the future there are many more uses will be found by the people.

Why is it that a few months after firing casting the finished artificial stone will appear warping, cracking phenomenon?

Mainly caused by the uneven mixing of poly waste fee resin with filler, pigment, and the incorrect ratio of accelerator, initiator and resin

. In the artificial stone matrix, that is, in the resin, filler, pigment and other mixture has been mixed well, the resin should be able to

so that the filler to maintain a uniform suspension state, until the resin gel. If the filler is poorly suspended in the artificial stone matrix,

deposited to the bottom of the casting body, it will cause differences in the distribution of filler on the top and bottom of the casting body. As the upper layer of resin more, curing

curing shrinkage exothermic more, shrinkage; the lower layer of resin less, curing less exothermic, shrinkage, the result caused by the products of warping

curvature or cracking.
