What is the reason for the damage of imitation granite?

【Summary Description】 Nowadays, more and more imitation granite is used for urban road laying, which brings us a lot of convenience. Laying roads with imitation granite not only saves costs, but also increases the beauty of the city. However, there are also many problems. After laying, there is a lot of damage. So what is the reason for the damage of imitation granite?

Nowadays, more and more imitation granite is used for urban road laying, which brings us a lot of convenience. Laying roads with imitation granite not only saves costs, but also increases the beauty of the city. However, there are also many problems. After laying, there is a lot of damage. So what is the reason for the damage of imitation granite?

1. Before laying, the bottom of the square brick floor is not compacted, causing the settlement and tearing of the bottom foundation part, resulting in cracking of the stone above.

2. Natural disasters and external forces caused by thought damage caused by the ground on the imitation of granite damage.

3. Natural defects in the manufacture of imitation granite. Imitation granite manufacturers believe that some marble has many natural defects, such as cracks, sand holes, loose, inclusions and so on. If better repair and compensation cannot be obtained in advance, these defects will be exposed to the defective place first, and then spread to the ground, causing damage, moisture and some harmful pollution. Such as silver, beige, golden flower and coffee net.

4. After the imitation granite is made, do not stay in a humid environment for a long time. The main component of imitation granite is calcium carbonate, which will expand under the action of water, so the loose part of the stone structure will break first, leaving a piece of gravel in the imitation granite. In this humid environment, the stone pit will continue to be pulverized, causing the surrounding stones to become loose.

5. The protection method is not used correctly. For some owners and builders, although the imitation granite has been coated with a layer of protective paint in advance, there are still some problems in the pavement of the ground. On the one hand, the reason for this phenomenon is that the cracks and loose parts of the stone are not repaired, and the larger water pressure generated by the moisture on the back of the stone will soon be destroyed; on the other hand, although the front side of the imitation granite also has a protective effect, the moisture on the ground will enter the stone from the cracks and loose parts of the stone, which will increase the humidity of the stone, thus forming a vicious circle.

In our daily life, stone can be seen everywhere, but not all stones can be used in construction. At present, due to the over-exploitation of some natural stones and the gradual shortage of natural resources, some imitation granite has gradually replaced natural stones. Compared with natural stone, imitation granite, higher smoothness, appearance color looks uniform, colorful.

Generally speaking, in the process of producing imitation granite, the manufacturer adopts advanced production technology, which is carefully selected in the initial selection, and then uses some large-scale equipment to make it into powder, and then uses some pressing equipment to make these The material is pressed into a fixed shape, the pressed blank is dried, put into a high-temperature furnace for high-temperature sintering, and then the manufactured product is cut and ground, and thus become the finished product we see. Because the imitation granite adopts special production process and formula raw materials, it mainly uses ceramic time, feldspar, ceramic and other raw materials. At the same time, it is calcined under some non constant temperature conditions, and high pressure is also used to form a dense structure similar to time spar inside the furnace body. This kind of imitation brick also adopts a complete process to make its quality uniform.

Imitation granite density is high, hard and wear-resistant, this kind of imitation brick water absorption rate is quite low, far less than 0.1, but also has anti-pollution, waterproof, acid and alkali resistance and other properties. Its strength is 3 to 5 times that of our ordinary granite, so it can be used in some environments with a large flow of people, and the cost is much lower than that of granite. Due to the high requirements for the preparation of raw materials for imitation granite, and the color can be artificially controlled, it can well restore the rich texture of natural stone, with a more realistic visual sense and touch, and seems to have the transparency of natural stone.

Imitation granite in the advanced production process to ensure that no polluting metal impurities, no radiation. At the same time, compared with natural stone, the color is relatively uniform and there is not so much color difference.
