Identification methods for stone materials

select The quality of processed finished decorative stone can be distinguished from the following four aspects: One observation, that is, observing the surface structure of stone with the naked eye. Generally speaking, stones with a uniform fine structure have a delicate texture and are considered excellent products of stone; The appearance of coarse-grained and unevenly structured stone is poor. In addition, due to the influence of geological processes, stone often produces some subtle cracks in it, and the stone is most prone to rupture along these parts, which should be carefully removed. As for the lack of edges and corners, it also affects aesthetics, so special attention should be paid when choosing. The second measurement refers to measuring the size and specifications of the stone to avoid affecting the splicing or causing deformation of the patterns, patterns, and lines after splicing, which may affect the decorative effect. Listen three times, that is, listen to the sound of the stone hitting. Generally speaking, high-quality stone has a crisp and pleasant knocking sound; On the contrary, if there are slight cracks inside the stone or if the contact between particles becomes loose due to weathering, the knocking sound will be rough and hoarse. Four tests, which use simple testing methods to inspect the quality of stone. Usually, a small droplet of ink is dropped on the back of the stone. If the ink quickly disperses and leaches out, it indicates that the particles inside the stone are loose or there are gaps, indicating poor quality of the stone; On the contrary, if the ink droplets remain in place, it indicates that the stone texture is good. suggestion 1. The stone has a radioactive certificate, please request it from the dealer when purchasing. Do not purchase without a certificate, and be aware that A-class products should be used for home decoration. 2. When choosing between marble and granite, marble should be considered first. Under normal circumstances, the radioactivity of granite is greater than that of marble. 3. In general, the consideration for stone should be black, gray white, flesh red, green, and red. From the perspective of radioactivity, from high to low, the order is: red>green>flesh red>gray white>white>black, basically in this order.

Inspection methods for stone materials

Inspection methods for natural decorative stone materials GB/T 9966.3-2001 Test Methods for Natural Decorative Stone Materials Part 3: Test Methods for Bulk Density, True Density, True Pore Rate, and Water Absorption Rate 1 Scope This standard specifies the equipment and measuring tools, specimens, test procedures, result calculations, and test reports used for the volumetric density, true density, true porosity, and water absorption of natural decorative stone materials. This standard is applicable to the testing of bulk density, true density, true porosity, and water absorption of natural decorative stone materials. 2 Equipment and measuring tools 2.1 Drying oven: The temperature can be controlled within the range of 105 ℃± 2 ℃. 2.2 Balance: maximum weighing 1000g, sensitivity 10mg; maximum weighing 200g, sensitivity 1mg. 2.3 Specific gravity bottle: with a capacity of 25mL to 30mL. 3 samples 3.1 Bulk density and water absorption test sample: The test sample is a cube with a side length of 50mm or a cylinder with a diameter and height of 50mm, with a size deviation of ± 0.5mm. Each group consists of five pieces. The sample is not allowed to have cracks. 3.2 True density and true porosity samples: Take about 1000g of clean sample and crush it into particles smaller than 5mm; Reduce the weight to 150g using the quartering method, and then grind it with a ceramic mortar to a size that can pass through 63? M standard sieve powder. 4 Experimental steps 4.1 Bulk density and water absorption rate 4.1.1 Place the sample in a drying oven at 105 ℃± 2 ℃ and dry it to constant weight. The difference in mass between two consecutive times should be less than 0.02%, and then cool it to room temperature in a dryer. Weigh its mass (m0) to the nearest 0.02g. 4.1.2 Soak the sample in distilled water at 20 ℃± 2 ℃ for 48 hours, then remove it and wipe off the surface moisture of the sample with a wrung out wet towel. Immediately weigh its mass (m1) to the nearest 0.02g. 4.1.3 Immediately place the water saturated sample in a basket and immerse the basket and sample together in distilled water at 20 ℃± 2 ℃. Weigh the sample in water (m2) (note to carefully remove any bubbles attached to the basket and sample during weighing), accurate to 0.02g.

What is natural stone?

1. Natural stone is mainly divided into two types in daily use: marble and granite. Generally speaking, anything with texture is called marble, and anything mainly characterized by speckles is called granite. This is speaking in a broad sense. Narrowly speaking, marble refers to the stone produced in Dali, Yunnan. In fact, there are not many stones from Dali in various places now. 2. Marble and granite can also be distinguished from geological concepts. Granite is an igneous rock, also known as acidic crystalline plutonic rock, which is the most widely distributed type of rock in igneous rocks. It is composed of feldspar, quartz, and mica, with silicon dioxide as the main component, accounting for about 65% to 75%. The rock is hard and dense 3. The so-called igneous rock is a rock formed by the condensation and crystallization of underground magma or volcanic eruption lava. The content of silicon dioxide and the properties and content of feldspar in igneous rocks determine the properties of the stone. When the content of silicon dioxide is greater than 65%, it belongs to acidic rock. When basic minerals such as orthoclase, plagioclase, quartz, etc. form crystals in this rock, it has a granular structure and is called granite.

Advantages and disadvantages of hotel tiles

1、 Durability The ground of hotels often experiences high-intensity impacts from people and logistics, making the durability of ground materials particularly important. Ceramic tiles, as a type of flooring material, are one of the commonly used choices for hotel flooring due to their hardness, wear resistance, corrosion resistance, and high temperature resistance. Compared to other materials, ceramic tiles have better resistance to compression and wear, and are less likely to be damaged or leave footprints and scratches even after prolonged use. 2、 Aesthetics There are various patterns and colors of ceramic tiles, which can be freely selected according to the hotel's decoration style. Moreover, the surface of the ceramic tiles is smooth and clean, and will not deform or discolor due to moisture or heat, making it less prone to dust accumulation. For places such as hotels that require high hygiene, the characteristics of ceramic tile surfaces also make cleaning very easy and less likely to breed bacteria. However, some people complain that the gaps between ceramic tiles are too wide, which can easily accumulate dirt and grime. 3、 Maintenance and upkeep The maintenance of ceramic tiles is relatively simple and can be done using household cleaning agents. Of course, excessive cleaning agents and brushes should not be used to avoid damaging the surface and color of the tiles. In addition, the anti slip properties of ceramic tiles also require regular inspection and maintenance by homeowners and hotel staff. Overall, as a hotel flooring material, ceramic tiles have incomparable advantages, but also have certain disadvantages. Hotel owners and designers need to consider the durability, aesthetics, and maintenance of ceramic tiles based on the specific situation of the hotel, and choose suitable floor decoration materials to provide a comfortable and safe living environment.
