Tile performance test sprinkled on it, will form water beads, is this tile good or bad?

All right! It shows that his water absorption rate is low!

A key point to measure the quality of ceramic tiles comes from [Grammy** Ceramics].

Water absorption: a term used to describe the degree of water absorption of ceramic products, like dry clothes immersed in water will absorb water, ceramic products also have a certain water absorption rate, the lower the water absorption rate, the more helpful it is to improve the other properties of ceramic products, such as strength, density, etc. Tiles with low water absorption will not crack or peel off due to severe thermal expansion and contraction due to climate change.

Water absorption is the basis of all the qualities of ceramic tiles!

Anti-fouling: If the surface of the ceramic is stained with dirt, if it is easy to wash off, then the better the anti-fouling performance. The determination of anti-fouling performance is to coat the surface of the brick with standard dirt and debris that is easy to produce traces, and after a certain period of time, different kinds of cleaning agents, such as bleaching powder, washing powder, acetone, hydrochloric acid solution, potassium hydroxide solution, etc. are commonly used cleaning agents.

Chemical resistance: refers to the resistance of tiles to chemical substances (e.g., acids, alkalis, salts).

It has good chemical resistance, and the tile will not change much even if it is in an acidic environment for a long time. Improving chemical corrosion resistance can extend the service life of ceramic tiles in their natural state, and the stronger the anti-fouling and anti-corrosion ability of tiles, the more convenient daily cleaning will be.

2. Six steps to buying tiles.

One, two, three, four, five, six.

Rubbing: Rubbing bricks by hand, the feel is heavy, and the bricks have high density and high hardness; The opposite is worse.

Scratch: try to scratch the glaze with a hard object, if there are scratches, it indicates that the quality of the glaze is not good, the hardness is not enough, in this case, after the glaze is polished, the brick surface is easy to hide dirt, and it is difficult to clean.

Knock: Tap the surface of the antique brick with your hand, if the sound is crisp and loud, it means that the tile is cooked and burned; If the sound is abnormal, it means that the sintering inside the tile is not good, and there may be internal cracks.

Look: Look at the section: The density of the section should be high.

Look at the surface: the surface reflectivity should be natural. Look at the suit:

The more the color changes, the more harmonious the application, suitable for large-scale overall paving, creating a harmonious aesthetic effect, of course, it must match the overall style of the home.

Drop: The easiest operation to test the water absorption rate is to drop water on the back of the tile, and the product with low water absorption rate and good internal quality will not have water droplets soaking or diffusion, and vice versa is poor. The water absorption rate of Grammy polished bricks is less than 5 thousandths, and the brick body is dense and of good quality.

Painting: Use a colored pen to scribble on the front of the antique brick, wipe it with a damp cloth after a while, if the light is as new as new and leave no traces, it means that the brick is strong in stain resistance. It is usually easy to take care of.

The tile is flat, the water cup is filled with water, the water falls from a height of 1,3-1,5 meters, and rolls away all around after touching the surface of the tile.

If the water droplets formed are large, flat, or adherent, it means that the surface of the tile is generally hydrophobic;

If it is not a drop of water, but a puddle of water, it indicates the surface finish of the tile. No way.

Such tiles are good tiles.

If the ground is hot, the weather outside is hot, and the surface of the floor tiles is cold, and the water vapor will bead when it is cold.

Solution: 1. Ventilation more, and more sun exposure if possible. At least this will not cause mold in areas with moisture, and if the ventilation effect is good, the moisture will disappear quickly.

2. If you are afraid of trouble, you can lay a layer of thermal insulation materials, such as foam, sponge, etc., on the two tiles in the cabinet, or brush a layer of thermal insulation paint (available in paint stores), which will not affect the appearance under the cabinet.

Insulating foam prevents the exchange of heat and cold, preventing water vapor in the air from condensing into water.

Of course, it is better to brush the insulating paint first and then lay the foam, but in the process of brushing the insulating paint, it is necessary to keep the tiles dry, that is, turn off the main water valve, and use an electric heater to warm up and down for a period of time, so that the surface of the ground can reach a similar temperature up and down, prevent condensation in the middle, and keep it until the paint dries.

Explain that the tile is glazed and does not absorb water. It may be that the air humidity is high, and the phenomenon of returning to the south is large.

The water droplets on the surface of the tile are mainly formed by the condensation of water in the air, and if the water absorption rate of the tile meets the standard, this situation cannot be regarded as a tile quality problem. This is the physical phenomenon of the weather, as long as the tile is waterproof, there is no problem, Henderson tile water absorption is very low, not easy to mold.

There are a lot of condensed water droplets on the surface of the tile, mainly because the indoor humidity is relatively large, and the mortar water analysis of the tiles shows that the indoor temperature is also low, so the water droplets will be condensed on the tile.
