What is the material of the bathroom retaining sink

Generally used.

Marble is used as a sink in the bathroom, and other materials can also be selected.

1. Plastic steel material: advantages: rest assured, strong waterproof, cheap, dozens to two hundred.

Disadvantages: not very beautiful, the visual effect of the plastic steel door is relatively low, many small restaurants use this, and it is easy to change color and deform.

2. Aluminum alloy: advantages: all aluminum alloys have a characteristic, that is, strong waterproofness, more styles, richer colors, and stronger ability to resist deformation. And the cost is cheap, anti-fouling, moisture-proof, rust-resistant.

Disadvantages: Because the material of aluminum alloy is different, the texture is different from that of the bedroom, the quality is unstable, the aesthetics are not too good, and the grade is very average.

3. Ceramic: Advantages: The biggest advantage of ceramics is that it is consistent with the texture of the bedroom door, the grade is high, and it is the strongest from an aesthetic point of view.

Disadvantages: The waterproofness and deformation resistance of ceramics are not as good as those of aluminum alloy doors. And it's expensive.

Granite material.

Granite is a kind of tectonic rock formed by the volcanic eruption of lava uplifted to the surface of the earth's crust in a molten state under considerable pressure, and the magma does not eject out of the ground, but slowly cools and solidifies underground. Granite is mainly composed of quartz, feldspar and mica. The feldspar content is 40%-60%, and the quartz content is 20%-40%, and its color is determined by the type and quantity of the components contained.

The rock is hard and compact.

Granite has a dense structure, high compressive strength, low water absorption, high surface hardness, good chemical stability, strong durability, but poor fire resistance.

Granite is a fine-grained, medium-grained, coarse-grained granular structure, or a patchy structure, its particles are uniform and fine, and the gap is small (porosity is generally, and the water absorption rate is not high (the water absorption rate is generally, and it has good frost resistance.

The hardness of granite is high, its Mohs hardness is about 6, its density is between g cm3, its compressive strength is 100-300MPa, of which fine-grained granite can be as high as 300MPa or more, and the bending strength is generally 10 30Mpa. Granite is often produced in the form of rock foundation, rock strain, rock block, etc., and is controlled by regional tectonics, and the general scale is relatively large, and the distribution is relatively wide, so it is easy to mine, easy to produce large materials, and its joint development is regular, which is conducive to mining stones with regular shapes.

Generally, the bathroom floor will be two or three points lower than the floor floor, which is the most basic for each decorator, if the conditions do not allow it, use marble or granite to make a threshold, the height is two or three centimeters, and it is easy to kick the feet.

Now granite is generally used. The whole is beautiful and beautiful. THE HEIGHT IS GENERALLY ABOUT 10CM.
