Extruded board is a good material with good thermal insulation and waterproof performance. However, an important factor determining the quality of materials is whether the materials are primary materials or waste recycled materials. Generally speaking, the performance of waste recycled materials is worse than that of raw materials. However, in order to improve production efficiency and reduce costs, some manufacturers in the market use waste materials instead of raw materials, which can save a lot of materials, but also bring problems, which need our attention, Here is your analysis.

首先，這種廢棄材料的力學性能較差，一般使用兩年左右會出現翹曲現象，翹曲處會產生大量裂紋，大大降低隔熱效果。其次，二次利用材料一般是加熱擠出循環，但我們知道一般絕緣板內部添加大量阻燃劑，所以在高溫條件下會有大量降解不能存在，因此，板容易點火，廢料一般難以循環，現階段技術不太成熟，所以板顏色差，很多人為了掩蓋這種現象，在材料表面涂上大量阻燃劑，會使板產生更大的氣味，對人體造成傷害。

First of all, the mechanical properties of this waste material are poor. Generally, it will be warped after using for about two years, and a large number of cracks will be generated at the warpage, greatly reducing the heat insulation effect. Secondly, the secondary utilization materials are generally heated and extruded. However, we know that a large number of flame retardants are added to the insulation board, so a large amount of degradation cannot exist under high temperature conditions. Therefore, the board is easy to ignite, and the waste is generally difficult to recycle. At this stage, the technology is not mature, so the board color is poor. In order to cover up this phenomenon, many people apply a large number of flame retardants on the material surface, which will make the board produce a greater smell, Cause injury to human body.

以上是擠塑板專家對廢料再加工制成的板材特性的介紹，所以在購買材料時一定要注意，這樣可能會對我們的身體造成傷害。以后購買時，如果不確定，可以購買擠塑板。

The above is the introduction of the extruded board experts on the characteristics of the boards made from waste reprocessing, so we must pay attention when purchasing materials, which may cause damage to our bodies. In the future, if you are not sure, you can buy extruded boards.
