一、看原料


原料是博天堂官网环保性能的关键因素。博天堂官网是由聚苯乙烯树脂生产而成。但是现在市场上的很多博天堂官网是由回收料制作而成的。市面上还有红色和黄色的博天堂官网一般和蓝色的博天堂官网差不多。下面三种分别是巴斯夫水晶原料、高级回收聚苯乙烯、回收聚苯乙烯。

二、看微观结构


博天堂官网的主要用途之一就是作为地暖保温层使用。博天堂官网保温的秘诀在于他的连续均匀表层及闭孔式蜂窝结构。泡孔越是均匀越好。下面是四种博天堂官网的微观结构图。白晶板的泡孔均匀且封闭。蓝板泡孔封闭良好。黑板没有泡孔基本没有封闭。

三、看导热系数


导热系数越低意味着阻热保温效果越好。

四、看容重


容重是博天堂官网的一个重要指标。直接和抗压性能挂钩。地暖用白晶板的容重一是35到36KG/m^3。好的蓝板的容重也是这个值。但是由于蓝板的原料的问题即使容重一样,白晶板的质量还是要比蓝板好。差一点的蓝板的容重是30KG/m^3左右。黑板的容重一般是在25KG/m^3左右。

First, look at the raw materials
The raw material is the key factor of environmental protection performance of extruding board. The extruder is made of polystyrene resin. But many of the extrusions on the market today are made from recycled materials. There are also red and yellow extrusions on the market that are generally similar to blue extrusions. The following three types are BASF crystal raw materials, advanced recycled polystyrene, and recycled polystyrene.

Second, look at the microscopic structure
One of the main uses of extruding plastic plates is to be used as a ground thermal insulation layer. The secret of extruding board insulation lies in his continuous uniform surface and closed Honeycomb structure. The more uniform the bubble hole, the better. The following are the microscopic structure of the four extruded plates. The bubble holes of the White crystal plate are uniform and closed. Blue plate bubble hole closed well. There is no bubble hole in the blackboard.

III. Look at the thermal conductivity
The lower the thermal conductivity, the better the thermal insulation effect.

Fourth, look at the weight
Weight tolerance is an important index of extruder. Directly linked to compressive performance. The capacity of the ground heating board is 35 to 36 KG/m <UNK>. The weight of a good blue plate is also the same value. However, due to the problem of blue plate raw materials, even if the capacity is the same, the quality of the White crystal plate is still better than the blue plate. The nearly blue plate has a capacity of about 30KG/m <UNK>. The capacity of the blackboard is generally around 25KG/m <UNK>.
