Tiles are absolutely irreplaceable in home decoration, especially in the decoration of kitchens and bathrooms. Inferior wood flooring will contain harmful substances such as formaldehyde, and tiles will also have radioactive substances, not "absolutely healthy and safe." In this era of environmental protection, buying a green and environmentally friendly ceramic tile is sure to be the unanimous pursuit of consumers. Below, Jiuzheng Building Materials Network will introduce you some small knowledge about environmentally friendly tiles, and hope to help you with your purchase.

First, why choose green tiles

Tiles are radioactive, especially glazed tiles, which are more radioactive. Tile materials are mostly derived from potassium-containing minerals such as mica, which contain certain radioactive materials. In fact, the radiance of tiles is not very large, even less than the radiation of mobile phones. However, in order to increase the surface finish of the tile, some manufacturers will add zirconium sand with high radioactivity to the raw materials. Living in such an environment for a long time, the safety and health of our family and our family cannot be guaranteed. There is no such safety hazard in environmentally friendly ceramic tiles. The radioactive level of ceramic tiles in environmentally friendly tiles is within the scope of Class A that can be used, and the use in home life can be completely unrestricted.

Second, how to choose environmentally friendly tiles

1. First of all, consumers must look for well-known brands when purchasing, and choose good brands that are trustworthy.

In the domestic first-line brands, ceramic tile products have been tested by the state. Whether a brand has obtained environmental protection marks, quality system certification and national inspection-free marks is very important. For example, Dongpeng, Marco Polo, Faenza tile and other big brands, from the data of the national quality supervision departments in recent years, the radioactivity of these brands is in line with national standards, you can rest assured to buy.

2. Look at the reflective level detection of the tiles and select the tiles of class A.

According to the newly revised "Code for Indoor Environmental Pollution Control of Civil Building Engineering", the radioactivity of porcelain tiles for interior decoration should be detected and controlled, and the test results are divided into three categories: A, B and C. Only Class A standard tiles can be used for home interior decoration, and consumers should choose Class A tiles when purchasing. Due to the difference in the appearance of the three types of tiles of A, B and C, there are some irregular decoration companies and small guerrillas who choose to use Class B and C tiles to impersonate Class A tiles for interior decoration in order to save costs. It is best to have a professional agency conduct radioactivity testing before you check in.

3. Observe the overall quality of the tiles and choose the best quality tiles.

A look: the color of the tile should be uniform, the surface finish and flatness should be good, the surrounding rules and patterns should be complete, and several pieces should be taken out from the same package to compare the defects such as chromatic aberration, deformation, lack of edges and corners; whether there are pinholes on the surface , cracks, bubbles, spots, pitting, bleed and so on. Second listening: With a hard object, the sound is crisper, the higher the porcelain, the better the quality. You can also use the left thumb, forefinger and middle finger to clip the corner of the tile and hang it down easily. Use your right index finger to tap the middle and lower part of the tile, such as the sound is crisp and bright, long and pleasing to the ear, such as the sound is dull and turbid for the next product. Three tests: the water droplets are on the back of the tile to see how fast the water is infiltrated. Generally speaking, the slower the water absorption, the higher the density of the tile, the better the quality; on the contrary, the faster the water absorption, the density is sparse, and the quality is Not as good as the former.
