What is the difference between good and bad tiles in the production process?

Wall tile is a kind of ceramic tile, which is a glazed fine pottery product with a water absorption rate of less than 21%. It is mainly used for indoor wall decoration. The wall tile is composed of three parts, the green body, the bottom glaze layer, and the top glaze layer.

The water absorption rate of the bottom of the billet is generally less than 3%, the number of grams of glaze applied to the bottom glaze is 40-60 grams, and the number of grams of top glaze is 90-160 grams. The floor tile is a kind of ground decoration material, which is fired with clay, with a wide variety of specifications, with a small quality and bulk density, relatively pressure resistance and wear resistance, can prevent moisture and other advantages, and some are glazed treatment, can play a decorative role. It is mostly used on the ground of public buildings and civil buildings.

Chuangrui tiles. 1: Good tiles need continuous innovation and research and development, which all need to be invested.

The research and development of a good brick and new color, from the proposal of the plan, to find the original large version, scanning plate making, source file modification, proofing trial production, market research, re-modification and finalization, small batch debugging, formula adjustment, re-sample, and then to a large number of online production, these investment of hundreds of thousands or even millions, it will be spent casually.

There will also be some factories to find some samples from other factories in the market, scan and copy the production, that is no need for R & D costs, but we will find that the products that come out of this way are different from the original, not to mention the internal quality, that is, the surface color and texture are not as clear and realistic as the original.

2: The raw materials and formula of good tiles are more optimized than the paving tiles, and the cost will also increase.

Some people will think that the raw materials for the production of ceramic tiles are cheap, that is, ordinary clay, quartz sand, glaze and some chemical materials, and the raw materials used by various brands are almost the same. This is not the case!

Can you simply mix these ordinary clay and quartz sand together, press them on a press, and burn them in a kiln to make good bricks? Definitely not! The same brick, the formula of each factory is different, and there are some key materials, which are expensive, plus more and less will affect the overall quality of the tile.

The difference between good tiles and bad tiles: *** The glaze of ceramic tiles should be smooth and fine, the gloss glaze should be crystal clear and soft, and the matte glaze should be mild and comfortable. Under sufficient natural light or fluorescent lighting, the brick should be placed 1 meter away vertically for inspection, and no obvious glaze defects should be visible.

The design of the brick color pattern with patterns should be meticulous and real, and there should be no obvious shortcomings such as color loss, disconnection, and displacement; On the contrary, bad floor tiles will have defects such as color cast, deformation, lack of edges and corners. The backside of the high-quality ceramic products is clear and detailed, and the glaze or damage is rare. If there is none, or if it is particularly vague, it is advisable to choose carefully.

Gently knock on the ceramic floor tiles, listen carefully to the sound, and listen to the better quality products. The secret recipe of raw materials for poor quality goods is unreasonable, the firing cycle time is short, the temperature is low, and there is an "empty" sound when hitting. Frequently asked questions about tile purchase:

In the production process of glazed bricks, in order to achieve the effect of whitening, zirconium silicate will be appropriately added, and some enterprises add excessive amounts for the production of ultra-white bricks, which is the main reason for the radiation of ceramic tiles exceeding the standard. The more detailed the floor tile particles, the greater the compressive strength, the compressive strength of the tile is related to its compressive bearing and compressive strength, and the hardness lies in its relative density.

In general, the finer the particle matter of the floor tile, the greater the density, the higher the compressive strength. Compared with wall tiles, it still needs a certain degree of water absorption to ensure that the hollow drum rate of wall tiles is reduced when the mixed mortar is applied to pavement, and the pavement is firm. It is only necessary to mix the mortar and select wall tiles with water absorption within a certain range, such as 10% or above.

For bricks of the same specification and model and the same texture, the heavier the brick, the better the quality. The reason is simple, the quality of the sand and the industrial kiln determines the relative density of the green body, and the relative density of the green body determines the durability of the product. Needless to say, in this fully competitive industry with hundreds of brands at a glance, in order to establish their own product advantages, they must not only continuously improve and invest in marketing, channels and product research and development, but also have outstanding self-control over product quality in order to survive and achieve a more benign development trend.

Good tiles are hard, smooth to the touch, look beautiful, and crisp to beat. And bad tiles are the opposite. It is recommended to lay tiles with good cement. Buy big brands of tiles.

The difference between good and bad tiles is that the hardness is different, the higher the hardness, the better the toughness, that is, the more wear-resistant, and then the sound is different, the sound of good tiles will not appear hollow sound and different colors, good tile color will be clearer, no matter from which angle there will be no reflection, and the pattern will be very delicate. In addition, the speed of dispersion is also different when dripping, and the faster the water droplets are dispersed, the more empty the inside, and therefore the worse the quality.

Tiles are divided into different brands and different quality, generally good tiles are not easy to be damaged, the fit is also better, and it will not wear out after a long time.

The main difference between good and bad tiles in terms of quality:

1. Appearance. Identifying the quality of the tile from the appearance of the brick, whether the size is standard is the key to judging the quality of the tile, measure the diagonal of the tile with a tape measure.

and whether the size and thickness of the four sides are uniform.

2. Chromatic aberration. Randomly unpack and check a few pieces and compare them one by one. It's normal to have subtle differences. (Different batches of tiles generally have color differences, it is recommended to buy enough at one time when purchasing.) Good quality tiles, green body color system.

1. Symmetry. 3. Flatness. The brick surface should be flat, there can be no concave and convex (turtle back), and the glaze layer and glaze layer of the brick can not be mixed with sundries.

4. Water absorption. It is the intrinsic quality of the tile. Test the water absorption: drop a drop of water on the brick and see how fast the water penetrates. Good tiles, water droplets will roll on the bricks.

Listen to the sound again: good tiles, the sound is crisp, indicating that the porcelain content is high. If the sound is "clicking" with the sound of stubble, it means that there are cracks hidden in the brick.

5. The thickness of the glaze layer. Glazed tiles are the front of the tiles, and the thickness of the glaze layer is the thickness of the glazed cross-section. The glaze is the most expensive material in the construction of ceramic tiles, and the thicker the glaze layer, the better the quality.

6. Weight. We all know that if two objects are the same volume, then the denser it is, the heavier it becomes. The tile is also heavier and the one is relatively better. It proves that this brick is dense and full of pottery powder, so it is more durable.

Raw materials: ceramic tiles are mainly fired with kaolin as the main raw material, the quality of kaolin in different mining areas is different, and the kaolin in good mining areas is of high purity. The same is true for ceramic tiles, the tiles with good raw materials are burned out, the green body is delicate, the color is white, and there is no graininess.

The raw materials of poor tiles are also relatively poor.

Density and weight: The green body of a good tile is well-made, the machine used is advanced, the green body is pressed by a high tonnage press, with high density, good flatness, and high tile weight. At the same time, its size and specifications are also relatively accurate, the error is small, it can be paved with narrow seams, and the water absorption rate is low.

The tonnage of the press of the poor tile is relatively low, the density of the tile body is low, the mass is relatively light, and the water absorption rate is high.

Handicraft control: good ceramic tile technology, good quality control. The flatness of the tile is high, the color is positive, there is no color difference, the hardness is high, there is no flaw in close observation, and the inspection is relatively strict.

Poor ceramic tile quality control is poor, flatness is poor, tiles are large and small, need to be adjusted by seams, and the hardness is low. Now the ceramic tile is tested by machine quality, the accuracy is relatively high, compared with the previous manual detection speed, the detection effect is good.

Stable quality: Good ceramic tiles are of stable quality, and long-term use is not prone to problems such as porcelain collapse, discoloration, glaze loss, wear, scratches, etc. Poor quality tiles are prone to the above problems.

Ceramic tiles have porcelain tiles (within low water absorption) and ceramic tiles (10%) from the water absorption rate. Generally, porcelain bricks are used for interior decoration, and terracotta bricks are used for exterior walls and courtyards. From the glazed surface, there are types of polished tiles, glazed bricks and other types, and glazed bricks are popular now.

Polished tiles are more wear-resistant than glazed bricks, but the glazed surface is not as good as glazed tiles. Therefore, the tile comparison should be compared in the same kind of ceramic tiles.

Tile purchase comparison.

First look at the tile flatness, color. Good tiles have high flatness and are flawless when you look closely. Surface flatness is measured by three points on the surface of the tile.

a.Center curvature - the distance by which the center of the brick deviates from the plane determined by 3 of the 4 corners of the brick.

b.Warpage – The three angles of the brick determine a plane, and its 4th angle deviates from that plane. The color is bright, and there is no color difference in the same tile.

Multiple tiles can be viewed on top of each other on a flat floor. The back of the tile is delicate, the texture is clear, and the brand logo is clear. The side body is delicate and flat.

Percussion, good tile sound crisp, loud, indicating high density, no pores inside, good porcelain.

Use a tape measure to measure the dimensions of the tiles, the sides and the diagonals. Error-free is better.

Detect the water absorption, pour water on the back of the tile, the tile that does not absorb water is porcelain tile, and the quality is better. Paint drops on the front, or apply with an oil-based marker, and scrub without penetration after 30 minutes. The lower the water absorption rate of the tile, the better the quality of the tile.

When purchasing tiles, you should compare them in the same type of tiles, or the same type of tile.

Good tiles require continuous innovation and research and development, which require investment.

The research and development of a good brick and new color, from the proposal of the plan, to find the original large version, scanning plate making, source file modification, proofing trial production, market research, re-modification and finalization, small batch debugging, formula adjustment, re-sample, and then to a large number of online production, these investment of hundreds of thousands or even millions, it will be spent casually.

There will also be some factories to find some samples from other factories in the market, scan and copy the production, that is no need for R & D costs, but we will find that the products that come out of this way are different from the original, not to mention the internal quality, that is, the surface color and texture are not as clear and realistic as the original.

TENDYO Plain Rock Slab (TD Plain Rock Slab) has its own R&D team, and attaches great importance to scientific research investment, new product development and new process improvement. The company has a high-standard R&D center, complete engineering and technical facilities and experimental conditions, and advanced level.

How to choose tiles.

Home decoration should buy tiles, how to buy value for money, satisfactory tiles also have a certain knowledge, in general the principle of buying tiles is: a look, two listens, three drops of water, four feet.

First, look at the appearance. The color of the tile should be uniform, the surface finish and flatness should be good, the surrounding rules should be regular, the pattern is complete, and four or five pieces should be extracted from a box to see if there are defects such as color difference, deformation, lack of edges and corners.

2. Listen to the sound. Tap with a hard object, the crisper the sound, the higher the degree of porcelainization, and the better the quality. You can also use the thumb, index finger and middle finger of the left hand to clip the corner of the tile, hang down easily, and tap the middle and lower part of the tile with the index finger of the right hand.

3. Drip test. You can drop water on the back of the tile to see how fast the water soaks after it spreads, generally speaking, the slower the water absorption, the greater the density of the tile; On the contrary, the faster the water absorption, the sparse density, and its intrinsic quality is superior.

Fourth, the measurement. The higher the accuracy of the side length of the tile, the better the effect after paving, and buying high-quality tiles is not only easy to construct, but also can save man-hours and accessories. Use a tape measure to measure whether there is a difference in the size of each tile, and the high accuracy is the top grade.

In addition, observe its hardness, ceramic tiles with good hardness, strong toughness, not easy to break and rot as the top quality. The edges and corners of the tile fragments are scratched on each other, and the broken fragments are inspected to see whether the broken parts are fine or loose, whether they are hard, brittle or soft, whether they leave scratches, or scattered powder.

Whether the size is standard is the key to judging the quality of the tile, measure the diagonal and quadrilateral size and thickness of the tile with a tape measure or caliper, whether the thickness is uniform, good tile, the sound is brittle, indicating that the porcelain content is high. If the sound is "clicking" with the sound of stubble, it means that there are cracks hidden in the brick.

Good tiles, the master installation is also convenient for construction, and the effect of installation is also standardized.

1. The color of the green body is different, and the color of the good tile is very unified, and it will not be mixed with other colors or there is a large color difference. 2. The cross-section is different, and the cross-section feels rough and has a great graininess, which means that the quality of the tile is not good, and the moisture is easy to invade. 3. The thickness of the glaze layer is different, the glaze layer is the positive surface of the tile, the highest value part of the tile is the glaze, the thickness of the glaze can be observed by the die-cut surface, if the glaze is thicker, the quality of the tile is very good.

4. The water absorption is different, if the tile is sprinkled with water and then quickly infiltrated into the tile, it means that the quality of the tile is not good, and the density is definitely not up to standard.
