1. Is the burning board marble?
Is the burning board marble? Combustion plate is a granite surface where liquefied gas and oxygen are burned by high temperature flame. Due to uneven expansion due to heating, it has a slightly concave-convex effect similar to litchi noodles, which has anti-slip effect. Due to the special conditions of granite formation and solid structural characteristics, it has the following unique properties:
1, and its elastic modulus is higher than that of cast iron.
2. Good wear resistance, 5- 10 times higher than that of cast iron.
3. Granite is non-conductive, non-magnetic and stable in field.
4, the thermal expansion coefficient is small, it is not easy to deform, similar to indium steel, and it is slightly affected by temperature.
5. It has good decorative performance and can be applied to public places and outdoor decoration.
6. Good rigidity and large internal damping coefficient, which is 15 times larger than that of steel. It can prevent earthquakes and shock absorption.
7. Granite is brittle, and only partially falls off after being damaged, which does not affect the overall flatness.
8. Excellent machinability: sawing, cutting, polishing, drilling, carving, etc. The machining accuracy can reach below 0.5μm, and the luminosity can reach above 1600.
9. Granite has stable chemical properties, is not easy to weather, and can resist the corrosion of acid, alkali and corrosive gases. Its chemical properties are directly proportional to the content of silicon dioxide, and its service life can reach about 200 years.
Second, the burning plate color types
There are many kinds of burnt boards, such as wulian burnt board, wulian braised board and wulian grey burnt board. In addition, it can also be distinguished from thickness, size and treatment:
According to the thickness: 2cm\2.5cm\3cm\4cm\5cm.
According to size: there are big boards and small boards.
According to the treatment: acetylene burning, litchi machine noodles, chopped axe noodles.
The above are all about whether the burning board is marble and the color type of the burning board. I hope it can help you understand the burning plate. Please continue to pay attention to more decoration knowledge, decoration company evaluation and decoration cases!
