Buildings in our lives require buildings. In general, building materials are the soul of a building. Granite is one of the building materials. Granite is a purely natural building material, and many buildings currently use granite. Granite can be divided into different types according to different structures, and can also be divided into various granites according to different minerals. But no matter which kind of granite, their overall attributes are the same, the following is a brief introduction to granite.
Granite generally has its own physical properties and chemical properties. The physical structure of granite is generally very tight and its pressure resistance is relatively strong. The color is diverse and it is the highest hardness of all building materials. Attracted the attention of many builders and attracted everyone's attention. Among the chemical properties, the main component of granite is silica, which accounts for 67% to 76%. In addition, aluminum oxide accounts for about 15% of all components. Other mines. The material accounts for other proportions. The composition of granite is mainly composed of three kinds of materials, which are common quartz feldspar and well-known biotite. Quartz accounts for the most proportion, generally 60%. Five to ninety percent, and the proportion of quartz is about 10% to 60%. The least is biotite, which usually only accounts for 10% to 15%. Granite has a strong thermal stability. In other words, the granite itself is not affected by the external temperature. Its temperature is very stable and its corrosion resistance is also very strong. Therefore, granite is used in many chemical reserve products.
The appearance of granite looks very beautiful and the colors are varied. According to the color, it can be divided into different types, such as red yellow red and black and beautiful cyan. For example, red granite. For rose red granite cherry red granite and so on. Granite is also very particular about maintenance. For example, the floor made of granite can not be waxed. If it is waxed, it will fall off easily. When people walk on the surface of granite, the wax will fall. All the work is in vain. Therefore, in the granite floor that has just been completed, we only need to carry out daily maintenance and maintenance, and do not need to do too much work, which also makes the maintenance work of granite floor simple and easy.
At present, granite is used in many fields because it is not only wear-resistant but also high in hardness, and it is not easy to cause damage, and it does not produce wood chips. The color is also the same. As long as it is maintained daily, it will not It is fading, and it is not afraid of wind and sun. Therefore, it is widely used and popular. However, it should be noted when using it. Some granites are radioactive. In this case, We should put it outside the house, otherwise it will have a certain impact on the human body. Since its main component is silica, it is a kind of acidic building material, so we should avoid contacting granite with alkaline objects, otherwise we should avoid contact with granite. A chemical reaction will occur, which will also have a certain impact on the granite itself.
Granite is a product of nature and a must-have in our lives. As long as you look closely, you will find granite everywhere in our lives.
