(1) ceramic tile material comparison:

(2) purchase guide:

1. Choose different ceramic tiles according to the functional space:

kitchen generally choose: bright glazed interior wall tiles, mainly because this kind of ceramic tiles are easy to clean and take care of, and 300*450 bricks with relatively large specifications can be selected in large kitchens

at present, there is a wide range of choices in the market for the selection of toilets. Products of 450*300600*30 specifications are more popular in the Shanghai market. It is quite atmospheric and has a strong overall sense after paving. Personalized consumers can choose products such as strip bricks and mosaics, which can be freely matched and combined for paving

living room, in view of the consumption habits in Shanghai, a large number of consumers choose the floor. In recent years, some consumers choose vitrified bricks. Compared with the floor, vitrified bricks are easier to take care of and maintain

2. Four tricks to choose tiles:

look: observe whether the brick surface is fine and uniform, and whether there are visible defects such as specks and holes

measurement: take a brick and measure whether its side length meets the requirements, then take several bricks and stack them together to compare whether their sizes are consistent. Take two bricks side by side and see whether the edge seam is small and straight, then the edge straightness is good; Then buckle the two bricks together to see whether the gap is small and straight, and the flatness is good. Whether the brick surface is concave or convex, it is better to be flat and slightly convex

knock: gently knock (or snap with your fingers) the suspended ceramic tile with a thin stick. The crisp sound indicates that the ceramic tile has no cracks, good sintering degree, low water absorption and high strength; If the sound is hoarse, the ceramic tile may have cracks; The sound "stuffy" indicates that the ceramic tile has poor sintering degree, high water absorption and low strength

drops: drop several drops of clear water on the back of the ceramic tile and observe the absorption speed. The faster the absorption, the greater the water absorption. Generally speaking, products with low water absorption have good sintering degree, high strength, good frost resistance and good product quality. Or apply several drops of colored liquid on the local surface evenly, wipe it with a wet cloth after a few seconds, and observe whether there are residual color spots on the surface. More color spots indicate that there are many pinholes, which are easy to get dirty, and the glaze quality is not high; If it cannot be wiped off, it means that the brick has high water absorption and poor anti fouling ability

3. Six methods for detecting the quality of ceramic tiles:

1. Drop a few drops of tea juice or water on the back of the ceramic tile. After a few minutes, depending on the degree of inhalation and diffusion of the water droplets, the quality is good if the water absorption is not high or low

2. Knock the ceramic tile and listen to whether the sound is crisp. The more crisp the sound is, the higher the vitrification degree, density and hardness are

3. Scrape the tiles with sharp objects to see if there are scratches. If there are scratches, it means that the glazing is poor and people are easy to slip. After the glaze on the surface is polished, the brick surface will be dirty and cannot be cleaned

4. If the color and chroma of ceramic tiles are clear and natural, it means that the porcelain degree is high, the chroma is not clear, and the porcelain degree is low

5. When shopping, observe whether there are pinholes on the surface with the naked eye within one meter. If there are, it means that the glaze is not fully fused, and it is easy to accumulate dirt

6. Observation of warpage: observe whether the side of the ceramic tile is straight with the naked eye. If the warpage is serious, it will affect the firmness of the ceramic tile in the future

4. Analysis of six tile laying methods for decoration:

tile adhesive: also known as dry sticking method, it is a new type of paving auxiliary material. It changes the wet method of mortar and cement. Tiles do not need to be soaked in advance, and the base surface does not need to be wetted. As long as the basic conditions of pavement are good, the operation condition can be greatly improved. Its adhesion effect is also better than traditional mortar cement, especially suitable for small and medium-sized projects and home decoration with small working surface and unsatisfactory working environment

colorful joint sealant: it is not ordinary colored cement, but is generally used for the ground or wall surface with joint pavement. It is characterized by strong color fixation, pressure resistance and wear resistance, non alkalization, non shrinkage and non pulverization, which not only changes the problem of water falling off and poor adhesion in the tile gap, but also makes the color of the gap and the tile match appear unified and coordinated, and complement each other

cross positioning frame of edge banding strip: the use of these auxiliary materials has greatly improved the construction technology of internal and external corners in pavement. The 45 degree trimming of ceramic tiles is no longer required, which greatly saves man hours and damages. Cross positioning can improve the joint accuracy of floor tile paving and simplify the construction process

combination of various specifications: its feature is to select a variety of floor tiles with different geometric sizes and pave them in groups according to a certain combination method. Because the floor tiles are combined in different sizes and in many ways, the geometric lines of the ground change immediately, which reflects the change and vividness in the order

floor tiles are composed of a variety of colors, which is the latest paving trend of Spanish tiles. It is paved by random combinations of floor tiles with different glaze colors. Its visual effects vary greatly, making people daydream. This is a challenge to our traditional aesthetic concept of "symmetrical unity". It is suitable for larger halls

seam paving: antique floor tiles are popular in the market now, which mainly emphasizes the return of history. The glaze is treated unevenly, and the straight edge is also made into a corrosive shape. When paving, leave necessary gaps and fill it with colored cement to unify the overall effect and emphasize the dignified sense of history

wall paving: the combination of 45 degree oblique paving and vertical paving makes the wall rich and varied from the original monotonous geometric lines, and enhances the three-dimensional feeling and active atmosphere of the space
