If there are old people and children at home, it is necessary to pay attention to whether the floor tiles of the bathroom are non-slip when decorating the bathroom. Anti-slip floor tiles are safer and can better protect family members from falling. Today, let’s talk about the purchase and maintenance skills of non-slip floor tiles.
1. The slip resistance of floor tiles of different materials
1. Whole body brick: good anti-skid property, general anti-skid brick belongs to whole body brick
The whole body brick is made by pressing rock debris under high pressure. The surface is not glazed, and the front and back sides have the same color. The surface of the whole body brick is relatively rough, so the anti-skid performance is better. Most of the anti-skid bricks on the market are full-body bricks.
2. Mosaic tiles: good skid resistance
Mosaic floor tiles are generally composed of dozens of small bricks to form a relatively large brick. Due to the small size of the blocks, there are gaps between the blocks, thereby enhancing its slip resistance.
3. Glazed tiles: good skid resistance
Glazed tiles refer to the tiles whose surface has been glazed. The surface is glazed and has strong anti-fouling ability. Although the anti-skid property is not as good as that of whole-body bricks, it is better than polished tiles and vitrified tiles.
4. Vitrified tiles: general slip resistance
Vitrified brick is a kind of brick with low water absorption rate. The surface is polished to a mirror effect. However, due to its strong hydrophilicity, it is more non-slip when encountering water. The more water there is, the more astringent the brick surface will feel. Therefore, the anti-skid property of vitrified tiles when they are dry is not as good as when they are wet.
5. Polished tiles: poor slip resistance
Polished brick is a kind of bright brick made by grinding and polishing the surface of the whole body brick. The surface is smooth and clean, so the anti-skid property is poor. It is not recommended to be laid in kitchens, balconies and other spaces with high anti-skid requirements.
Second, floor tile anti-skid performance test method
At present, the country does not have very detailed standards for anti-skid bricks. In order to meet the needs of consumers, many merchants sell bricks with poor anti-skid properties as anti-skid bricks. Therefore, consumers need to know some methods of testing the slip resistance of floor tiles in order to buy truly high-quality non-slip tiles.
1. Check the coefficient of friction of floor tiles
As mentioned earlier, the slip resistance of floor tiles depends on the coefficient of friction on the surface of the floor tiles. According to international standards, the coefficient of friction of floor tiles can be divided into five grades.
Friction coefficient and safety level of floor tiles
Less than 0.34 has poor skid resistance and is extremely dangerous
Poor skid resistance between 0.35-0.39, very dangerous
Poor skid resistance between 0.40-0.49, dangerous
More than 0.5 has better anti-slip performance and meets the safety level
Above 0.6, good skid resistance, very safe
In the national standard of my country’s ceramic floor tiles, the test method of the friction coefficient is clearly included, and the manufacturers of the ceramic floor tiles are also required to provide the data and test methods of the friction coefficient when the products leave the factory. Therefore, when purchasing non-slip bricks, it is necessary to ask the merchant to give the friction coefficient of the brick, and choose a product with a higher friction coefficient.
