Why is imitation granite damaged

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

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

 

1. Before laying, the bottom of the square brick ground is not compacted, causing the settlement and tearing of the bottom foundation part, causing the upper stone to crack.

 

2. Natural disasters and mental injuries caused by external forces lead to the destruction of granite-like rocks on the ground.

 

3. Natural defects in the manufacture of imitation granite rocks. Imitation granite Rock manufacturers believe that some marble has many natural defects, such as cracks, sand holes, looseness, inclusions, etc. If we cannot get better repair and compensation in advance, these defects will first be exposed to the defective place, 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 stone is made, do not stay in a humid environment for a long time. Imitation granite stone is mainly composed of calcium carbonate, calcium carbonate 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 stone. In this humid environment, the stone pit will continue to be crushed, loosening the surrounding stones.

 

5. The protection method is not used correctly. For some owners and construction personnel, although the imitation granite rock 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 have not been well repaired, and the large water pressure on the back of the stone due to moisture will soon be destroyed. On the other hand, although the front side of the imitation granite stone 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 of the stone can be used for construction. At present, due to the excessive exploitation of some natural stones, natural resources are gradually in short supply, and some imitation granite stones have gradually replaced natural stones. Compared with natural stone, imitation granite stone has higher smoothness, uniform appearance and bright color.

 

Generally speaking, in the process of producing imitation granite rock, the manufacturer adopts advanced production technology, 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 press these materials Into a fixed shape, dry the pressed blank, put it into a high-temperature furnace for high-temperature sintering, and then cut and grind the manufactured product, and thus become the finished product we see. Because imitation granite rock uses special production process and formula raw materials, mainly using ceramics, feldspar, ceramics and other raw materials., And in some non-constant temperature conditions of calcination, but also the use of high pressure, can be formed in the furnace body similar to the dense structure of the timely spar, and this kind of imitation brick also uses a complete process, so that its quality is uniform.

 

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

 

Under the guarantee of advanced production technology, the rock does not contain polluting metal impurities and radiation. At the same time, compared with natural stone, the color is relatively uniform, and there is not so much color difference.
