Buy plastic floor notes

After the floor tile is paved, the use of the floor will be subject to stress (such as furniture, people, etc.) to produce depressions, which will wear under friction and will be affected by heat, water, etc. All these effects will affect the floor tiles. The service life and appearance of decorative effects, so the floor tiles should have certain physical properties.

1. Thermal expansion coefficient: It reflects the change of the length of the plastic floor tile at different temperatures (2 "C and 40 Â°C). The greater the coefficient of thermal expansion, the greater the deformation of the floor tile when it is heated, affecting the effect of paving.

2. Heat loss rate and heating length change rate: Plastic floor tiles lose a part of their mass and produce a certain length of change at higher temperatures. If the quality loss rate and length change rate of a certain floor tile after heating is very small, it indicates that the tile of this type has stable performance after being heated and has a long service life.

3. The rate of change of water absorption: After the plastic floor tile is paved, it will often come in contact with water. If it is scrubbed with water or cleaned, or accidentally spilled a cup, etc., the floor tile will absorb water and the length will increase. This will make the shop The flat floor surface is tilted, so floor tiles with a small change in length after water absorption should be selected to ensure flatness after laying.

4. Concavity: This property reflects the thickness variation of plastic floor tiles under certain pressure. Plastic floor tiles are subjected to various objects and the pressure exerted by the human body during use. Under these pressures, the floor tiles should be as small as possible in order to maintain a flat surface on the floor of the bricks and make them have a longer service life.
