The residual depression of plastic flooring, international standard standard is EU EN433, it has its specific test method.
This is its test experiment:
In the same -quality floor, EN433 is to measure plastic flooring floor An important symbol of good or bad.
Generally, the plastic floor with a foaming back layer will reach about 0.2mm. A major disadvantage of plastic floor.
We judge that a brand with a foaming back layer plastic floor is quality and bad, and the most important thing should be the residual depression value.
It is also a foaming back layer floor. Due to the different process, raw materials, and product structure, the residual depression is very different.
Like the two brand flooring I saw with my own eyes, there are certain marks on the surface after using it for a period of time, but the residual depression of the Armstan brand is higher than other brands. a lot of.
Product introduction:
Floor residual depression test machine
Also known as the floor residual indentation test machine, the test machine is a method to determine the residual depression of the elastic floor. Essence The difference between the initial thickness and the thickness measured after the loading is removed, and the distance between the floor materials between the two parallel boards under the specified loading capacity. The sample is subject to static static, and the thickness before the force is measured and the thickness after the recovery period. Main technical parameters
