Don't be afraid of being pitted any more. Lao Zhang will teach you to buy tiles in ten minutes!

Hello, Lao Zhang, I'm here again. Today, I will explain the selection of tiles and the skills of paving. As we all know, decoration is a very troublesome thing, but it is worthwhile to work hard for your own warm nest. When it comes to tiles, tiles are usually laid about a week after hydropower enters the site. Therefore, the choice of tiles must be determined as soon as water and electricity enter the site, because the processing and transportation of tiles takes time.

PART 1: As the saying goes, what preparations do you need to make before buying tiles?

As an ordinary consumer, people often feel at a loss when buying tiles and often don't know what to choose. What kind of problems should I pay attention to before placing an order?

First, the links that are easily overlooked in the budget.

Now everyone is more sensitive to the price of ceramic tiles, and they will pay special attention to it when purchasing, but when they finally place an order, they find that there will still be a big overrun. What is the reason? In fact, this is to ignore some links when making a budget. Specifically, there are the following aspects:

Wall tiles: Because the tiles and waistlines of wall tiles are calculated separately, we should consider not only the price of tiles, but also the price of waistlines of tiles. When consulting and collecting prices in the market, we should not only remember the price of bricks, but also remember the price of matching the waist line of tiles.

Floor tile: In addition to the price of the brick itself, we should also pay attention to the price of the corner line. When laying floor tiles, whether it is necessary to make floor tiles and whether there is a special processing place must be considered.

Second, determine what kind of brick is good.

Now it is generally believed that the products of famous brands are the best. In fact, I personally think this view is questionable. Whether it is a well-known product or an unknown product, the key is that the brick that suits you is the best. For example, the atmosphere of 800 shops, but if it is about 20 square meters, it is not applicable; Imported bricks are good, but because rice is limited, it is unrealistic to have problems with that pot at home every day after buying it back. Therefore, suitable and suitable ceramic tile products are the best.

Third, consult more friends to understand the cost performance of products.

You can learn more about the knowledge and purchasing skills of ceramic tiles through various channels.

Fourth, don't ignore the investigation of the strength and after-sales service of the merchants.

When buying a product, besides considering the brand and price of the product, don't ignore the investigation of the strength and after-sales ability of the merchant. Do you dare to pick things in a shop with a dozen brands with a small door link? Can you count on his after-sales service? So try to consider those powerful standardized businesses ordering products. At the same time, we should also take pains to ask after-sales questions, such as the return of goods and the solutions to quality problems. What I want to say is that there is no brand without quality problems. Only after these are clearly implemented can we place an order and prevent problems before they happen.

The second part: according to the technology and characteristics, what kinds of tiles are roughly divided into?

First, glazed tiles

This is a glazed brick. According to different raw materials, it can be divided into two types: ceramic glazed tiles, which are made of clay and have high water absorption and relatively low strength. According to the local soil quality, there are red soil and white (yellow) soil. Porcelain glazed tiles, that is, porcelain clay fired, have low water absorption and relatively high strength. Its main feature is that the back color is grayish white. According to the different luster, it can also be divided into the following two types: bright glazed tiles and matte glazed tiles.

Second, the whole brick

The surface of the brick is not glazed, and the material and color of both sides are the same, hence the name. Integral brick is a kind of wear-resistant brick. Although there are still varieties of infiltrated monolithic bricks, their colors are relatively inferior to glazed tiles. Generally, it is rarely used on the wall, and most non-slip bricks belong to the whole body brick.

Third, polished tiles.

The surface of the brick body is polished, which is a kind of bright brick. Polished brick is a derivative of monolithic brick. Compared with the rough plane of the whole brick, the surface of polished brick is smooth. Hard and wear-resistant, suitable for most indoor spaces and indoor environments except bathrooms and kitchens. Based on the application of flower infiltration technology, polished tiles can make various stone-like and wood-like effects.

Fourth, vitrified brick.

It is a kind of reinforced polished brick, which contains a high proportion of quartz sand (the main raw material for making glass) in addition to porcelain clay. High temperature firing. The texture is harder and more wear-resistant than polished tiles. Better end it.

Verb (abbreviation of verb) mosaic

It is a special kind of brick, which generally consists of dozens of small bricks to form a larger brick. Divided into ceramic mosaic, marble mosaic and glass mosaic.

Part III: What are the characteristics of judging the quality of ceramic tiles?

First, scale.

The product size is uniform, which can save construction time, clean and beautiful.

Second, the water absorption rate

It is a term used to describe the degree of water absorption of ceramic products. Just as dry clothes absorb water when immersed in water, ceramic products also absorb water to a certain extent. The lower the water absorption, the more helpful it is to improve other properties of ceramic products, such as strength, density, etc. These properties will be improved to varying degrees with the decrease of water absorption. Ceramic tiles with low water absorption will not crack or peel off because of climate change.

Third, the flatness

Refers to the levelness of tile surface. The smoother the surface, the better the paving effect. When the flatness of the tile surface reaches a certain standard and the tile is laid correctly, there will be no arching or subsidence. Ceramic tiles with good flatness are easy to construct, and the ground is flat after construction without bending or warping.

Fourth, strength.

Wear resistance is described by the volume of ceramic tile powder ground under a certain force, a certain abrasive and a certain number of revolutions. The more ceramic tiles are ground, the worse the wear resistance. Ceramic tiles with good wear resistance are resistant to heavy pressure, difficult to wear and durable, especially suitable for public places.

Fifth, color difference.

Put the tiles flat on the floor, one square meter together, and see if there are different colors or not connected from three meters, causing aesthetic obstacles.

Sixth, radioactivity

When some special elements split protons in the process of electron transition, they will produce some rays harmful to human body. We call this property of elements radioactivity.

Seventh, antifouling performance.

The surface of ceramics is stained with dirt, and the easier it is to wash off, the better the antifouling performance. The determination of antifouling performance is to coat the surface of brick with standard pollutants that are easy to produce traces, and then clean it with different kinds of cleaning agents after a certain period of time, such as bleaching powder, washing powder, acetone, hydrochloric acid solution, potassium hydroxide solution and so on.

Part IV: What are the main skills of buying ceramic tiles?

Introduce everyone.

First, check

Check the product packaging box with the factory name, address, product name, after-sales service telephone number, specification, quantity, trademark, production date and implementation standard. For ceramic tiles, CCC certification mark should be checked. Indoor decoration of ceramic tiles, radioactive nuclides should be selected to meet the requirements of Class A products.

Second, look.

Good quality ceramic tile glaze should be smooth and delicate, shiny glaze should be glittering and translucent, and matte glaze should be soft and comfortable. When the brick is placed at a distance of 1 m, no obvious glaze defects should be seen under sufficient natural light or fluorescent light. Pattern brick pattern should be delicate and realistic, without obvious defects such as lack of color, broken line and dislocation. The shading and trademarks on the back of high-quality ceramic products are clear and complete, with few glaze marks or defects.

Third, fight.

Good product size deviation is small. Take out four or five pieces from a box to see the flatness. You can press the edges of two bricks together to see if there is a gap. Good products have small deformation, and the brick surface is smooth and beautiful after paving; Look at the color difference of the product, put a few bricks together and look carefully in sufficient light. Products with different shades of color between products have poor overall effect after paving; Finally, check whether there are any defects such as color difference, deformation and lack of edges and corners.

Fourth, listen

Tap the tile gently and listen to its sound carefully. The sound of products with better quality is crisp and pleasant. Inferior products will make an "empty" sound when they are knocked because of improper raw material formula, short firing cycle and low firing temperature.

Fifth, okay.

Weighing the product weight, the ceramic tiles with the same specifications have low water absorption and good internal quality.

Sixth, Didi

Drip test. You can drop water on the back of the tile to see seepage velocity after the water is dispersed. Generally speaking, the slower the water absorption, the greater the density of tiles; On the contrary, the faster the water absorption, the rarer the density and the better the internal quality.

Part V: What are the misunderstandings in purchasing ceramic tiles?

1. The thicker the tiles, the better?

This is a common misunderstanding. The quality and thickness of ceramic tiles are not directly related. The quality of tiles ultimately determines the density, dimensional error, warping and other indicators of tiles. The higher the density, the better the quality. As long as the general civil tiles reach the basic thickness, unless there are special requirements, they don't have to be made very thick, such as industrial tiles and square bricks used in factories; Some manufacturers in Shandong may have relatively cheap raw materials and thick bricks, but they cannot prove that this kind of brick is a good brick. Similarly, in order to save energy, ceramics made in Japan are relatively thin, but the accuracy and quality of bricks are above the standard.

Second, what is the difference between vitrified tiles and polished tiles?

1, ceramics with water absorption less than 0.5% are called vitrified tiles, also called all-ceramic tiles, and polished tiles have a low water absorption of 0. 5%, also belong to vitrified brick. It is characterized by large-tonnage pressing and high-temperature sintering above 65438 0250℃.

2. Polished tiles are obtained by mirror polishing vitrified tiles. Because the water absorption rate of early polished tiles could not meet the specific requirements, it may be the carelessness of the industry or the intentional action of the industry. Because of their relatively high water absorption, they have a fatal defect: they are easy to get dirty, which is caused by concave-convex pores left by polished tiles during polishing. These pores will hide the dirt and shelter the dirt, so that the polished tiles will change color when they talk about pollution, and even some tea leaves will not be able to return to the sky when they fall on the polished tiles. Therefore, there will be a misleading statement that "polished tiles are poor and vitrified tiles are good" in the market. However, with the improvement of ceramic tile manufacturing technology and surface treatment technology, the antifouling ability is further improved. Compared with the plane roughness of the whole brick, the polished brick will be much smoother. Polished tiles are hard and wear-resistant, and are suitable for most indoor spaces except bathrooms, kitchens and indoor environments. Polished tiles can make various stone-like and wood-like effects. Maybe everyone is aware of this. Later, some polished tiles with good quality were added with antifouling layers when they left the factory. Common specifications of polished tiles are 400x400mm, 500x500mm, 600x600mm, 800x800mm, 900x900mm,1000 x1000 mm.

3. Vitrified tiles and polished tiles on the market are actually similar products if their water absorption is the same. The lower the water absorption, the better the vitrification degree and the better the physical and chemical properties of the product. Vitrified brick refers to the physical and chemical properties of brick, and polished brick refers to the polishing process after sintering.

Third, what is antique brick? Is it different?

Antique brick, including retro brick, is not the standard title of China ceramic construction industry. Just like the saying that there is no modern brick, antique brick evolved from colored glazed brick. The so-called antique refers to the effect of bricks, which should be called antique tiles. Antique bricks are not difficult to clean. Antique brick imitates the old style and attracts people's attention with its unique classical charm. In order to reflect the vicissitudes of the years and the heavy history, antique bricks create a nostalgic atmosphere through styles, colors and patterns.

Fourth, can wall tiles and floor tiles be mixed?

1, indoor tiles can be divided into wall tiles and floor tiles according to the location of paving. Experts say that wall tiles should strictly belong to ceramic products, and floor tiles are usually porcelain products. Their physical properties are different, from the choice of clay composition to the firing process. The water absorption of wall tiles is about 10%, which is several times higher than that of floor tiles with water absorption of only 1%.

2. Floor tiles with low water absorption should be laid on the floor of bathroom and kitchen, because the floor will often be washed by a lot of water, so that the tiles will not be affected by water vapor and absorb stains. Wall brick is a glazed tile with high moisture content, and its back is generally rough, which is also conducive to the adhesive to stick the wall brick to the wall. Floor tiles are not easy to stick on the wall, and wall tiles will absorb too much water when used on the ground, making it difficult to clean. It can be seen that wall and floor tiles cannot be mixed.

3. Before laying the front wall and ground, the base should be cleaned up. If there are decorations such as lime putty, latex paint and wallpaper on the wall, or there is dirt on the ground, it must be cleaned up, otherwise the cement mortar will not be firmly bonded to the base; In addition, if there are cracks in the wall itself, proper treatment should be done before sticking bricks to avoid cracking or falling off of wall bricks caused by the expansion of cracks in the grass-roots structure in the future; Also, for the ground and wall with large difference in flatness or verticality, cement mortar should be used for leveling.

4. Laying sequence should pay attention to the tile from the inside out. If there is a slope or floor drain on the ground, pay attention to the slope in the drainage direction; The wall brick should be laid from bottom to top, and for the sake of beauty, the bottom brick should be attached afterwards. After the wall tiles are pasted, press the floor tiles again. Half a brick, try to put it under. In addition, one wall cannot be glued to the top at a time to prevent the tiles from collapsing due to heavy weight.

5, the wall brick should be fully soaked because the wall brick has a high moisture content, and this feature must be taken into account when pasting. Before tiling, the base should be fully watered and wetted, and the tiles should be soaked in water for at least 20 minutes, and then fully dried in the shade before use. Otherwise, the moisture in the mortar will be quickly absorbed by the dry base and ceramic tiles and quickly coagulated, which will affect their bonding fastness. Otherwise, the wall brick will absorb water from the cement, so that the cement can not play the role of adhesive. In addition, the water absorption rate of each brand of wall brick is different, depending on the experience of the construction team.

5. Why should tiles be soaked in water?

1, soak the brick in water before sticking it.

In order to make the pores fully absorb water, if it is too dry, the service life will be greatly reduced. Wipe the cement mortar after absorbing enough water, so that the water in the cement mortar can not be absorbed, and the paving quality can reach a certain standard, and it is not easy to empty drum, fall off or even crack.

2. The soaking time of ceramic tiles.

In principle, it is good to absorb enough water, and the tiles are not soaked in water. Generally, the soaking time can be controlled at two hours. 3. How to make tiles?

It's very simple. Just find a big basin and completely immerse the bricks. When moving bricks, you should handle them with care, otherwise it is easy to fold corners and porcelain surfaces.

Today, I have talked a lot about this. I hope you can refer to it when you buy tiles.
