When you go to the building materials market to buy tiles, shopping guides generally recommend glazed tiles or vitrified tiles. What do you know about glazed tiles? Glazed tiles are the most common types of bricks in decoration. On the ceramic market, there are a large variety of glazed tile brands. Tiles can be divided into different categories according to different classification methods such as shape, raw materials, etc., such as ceramic glazed tiles, cool surface glazed tiles and so on. In the home improvement, the frequency of using glazed tiles is getting higher and higher, and some of its properties can meet people's needs. However, in fact, there are not many people who really know about glazed tiles. Here I will tell you about the relevant content of glazed tiles. I hope to help everyone.
First, what is a glazed tile
The glazed tile is a ceramic tile whose surface is burned by glazing at high temperature and high pressure. The ceramic tile is composed of two parts: earth embryo and surface glaze. The main body is divided into clay and porcelain clay. The back surface of the clay is baked. The back of the red, porcelain clay is gray. The surface of the glazed tile can be made with various patterns and patterns, which is richer than the color and pattern of the polished tile. Because the surface is glaze, the wear resistance is not as good as that of the polished tile.
Second, the advantages and disadvantages of glazed tiles
advantage:
1. Color, pattern rich, easy to clean, suitable for kitchen and bathroom.
2. Surface strength, wall and floor dual purpose. Compared with vitrified tiles, the advantages are impervious, not afraid of dirt, good slip resistance, and the surface can be burned with various patterns and styles. Although the wear resistance is worse than that of vitrified tiles, the qualified products can meet the needs of home use.
3. Impervious, seamless splicing, good toughness, basically no fracture phenomenon.
4. Water absorption: Water absorption> 10%.
5. Resistance to quenching and rapid heating: refers to a rapid temperature change without cracking. The difference between hot and cold temperature is 130 ± 2 "C.
6. Bending strength: The mean value of bending strength is not less than 16MPa, and the average value of bending strength is not less than 13MPa when the thickness of brick is ≥7.5mm.
Disadvantages:
1. The surface is glaze, wear resistance is not as good as polished tiles.
2. During the firing process, pinholes, cracks, color difference glazes, etc. were observed.
3. Look at water absorption: good bricks, high density of pressing, good porcelain, low water absorption.
Third, to choose a good glazed tile must master the following five steps:
1. Surface quality: visual inspection of the glazed surface
The back of the brick should not have a 1/2 block bump; the color of the brick should be the same; a good glazed tile should have no defects such as edge stripping, lack of glaze, and brown eyes.
2. Various ratios: the density and water absorption of the tested bricks
Tap the brick surface with a metal object and listen to the sound. In general, the crisp sound has a high density, high strength, low water absorption, and good brick quality; conversely, the quality of the brick is poor.
3. Dimensional inspection: using the ruler size error
Good glazed tiles, strict error limits. In general, the long and wide errors do not exceed ±0.8 mm; the thickness does not exceed ±0.3 mm. At the time of inspection, random sampling should be performed, the quantity being about 10% of the total, but not less than 3.
4. Flatness check: contrast flatness and squareness
Feel free to put two bricks face to face to see if there is a bump. If the bricks are close together and the circumferences are basically coincident after rotation, it can be considered that the squareness and flatness are good.
5. Identification: Obtain Factory Inspection Report
Products sold by regular merchants are accompanied by factory inspection reports. Purchase at the time of purchase and check carefully to see if they match.
Editing summary: The above is about the introduction of glazed tiles, if you are interested in glazed tiles may wish to look at some of the relevant information on the glazed tiles, the specific purchase of glazed tiles must be different when comparing different brands, and then pick the most For their own products, I hope this article can help to meet the needs of friends!

Glazed tiles
The heating element give off the far infrared energy waves directly, heating the whole environment, people and objects. The electric infrared heating panels can be built with high thermal insulation material, so that the heat can be stored and still release within a certain time after the power outage. It is much more safe and efficient. This is a new concept of healthy and comfortable heating way.
