The quality of finished finished stone can be identified from the following four aspects:
A view: the surface structure of the stone is observed with the naked eye. In general, the uniform fine material structure stone has a delicate texture, which is a good stone material; the coarse grain and the unequal grain structure stone have poor appearance effect, mechanical mechanical properties are not uniform, and the quality is slightly poor. In addition, due to the influence of geological effects in natural stone, some fine pulsation and micro-cracks are often generated in it, and the stone is most likely to rupture along these parts, and should be removed. As for the lack of edges and angles, it is more important to affect the appearance, especially when choosing.
Two quantities: the size specifications of the stone. So as not to affect the splicing, or cause the pattern, pattern, and line deformation after splicing, affecting the decorative effect.
Three listening: Listen to the sound of the stone. In general, the quality of the stone with good internal density and no micro-cracks is crisp and pleasant; on the contrary, if there are micro-cracks or fine veins inside the stone or the contact between the particles becomes loose due to weathering, tapping The voice is hoarse.
Four tests: Use a simple test method to check the quality of the stone. Usually a small drop of ink is dripped on the back side of the stone. If the ink is quickly dispersed and leached everywhere, it means that the inner particles of the stone are loose or there are micro-cracks, and the quality of the stone is not good. Conversely, if the ink drops do not move in the original place, it means The stone is dense and the texture is good. In the selection of finished plates, because the stone raw materials are natural, it is impossible to have the same texture, and the level of the process in mining and processing is also different. Most of the stone is graded, and many distributors are also priced. However, there are also a few who do not distinguish, shoddy, and deceive consumers. In order not to make mistakes, the average consumer is best to contract the construction of the stone without packaging, personally go to the building materials city to buy.
There are a few things to keep in mind when buying stone:
1. Granite stone: Granite stone has no colored stripes, most of them only have colored spots, and some are solid colors. The finer the mineral particles, the better, indicating that the structure is tight and strong.
2, marble sheet: marble material mineral composition is simple, easy to process, most of the texture is fine, the mirror effect is better. The disadvantage is that the texture is softer than granite, and it is easily damaged when it is hit by hard and heavy objects, and the light-colored stone is easily contaminated. The marble floor is selected as much as possible, and the striped fabric is better when the table top is selected. Other selection methods can refer to the selection method of granite.

Motion Sensor Floodlight with aluminum heat sink material and design to prevent the LED smart floodlight motion sensor from overheating and ensure that the lifespan of the exterior motion flood light with socket can reach 50,000 hours. The motion sensor floodlight adopts an intelligent sensor. When someone passes through the sensing area, the outdoor motion sensor flood light will light up; when the person leaves the sensing area for a period of time or no one passes by, the light will not light up.
