说到挤塑板大家应该是比较熟悉了，但是由于它的需求量的增加，导致了一些乱象的发生，市场上上的产品也是各种各样的都有，那么究竟有哪些方法能够帮助我们去选择它呢?

挤塑板是由聚苯乙烯树脂生产而成。但是现在市场上的很多是由回收料制作而成的。很少是有正规厂家生产的。从原材料看挤塑板优劣排序：白晶挤塑板>蓝色挤塑板>黑色挤塑板。市面上还有红色和黄色的挤塑板一般和蓝色的挤塑板差不多。

看微观结构

它的主要用途之一就是作为地暖保温层使用。它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。三种微观结构分别为白晶板、蓝板、黑板。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。

看手直按压效果

白晶板经按压后肉眼基本看不出来。好的蓝板有较小的印。差的蓝板的凹陷很明显。黑板直接损坏了严重。

看使用寿命

一套房子的寿命一般是50年以上。地暖作为房屋的隐蔽工程如果不能与房屋同寿命，就意味着在使用过程中会重新安装。经试验表明，白晶板的使用寿命可以达到50年。好的蓝板的使用寿命可以达到30年，差的蓝板一般可以使用15年。黑板的使用寿命一般是5年。

When it comes to the extruding board, we should be familiar with it, but due to the increase in its demand, it has led to the occurrence of some chaos, and the products on the market are also of various kinds. So what are some ways to help us choose it?
The extruder is made of polystyrene resin. But much of the market today is made from recycled materials. Very few are produced by formal manufacturers. From the raw materials to see the advantages and disadvantages of the squeeze molding board: Baijing; Blue extruded board & GT; Black extruding board. There are also red and yellow extrusions on the market that are generally similar to blue extrusions.
Look at the microstructure.
One of its main uses is as a geothermal layer. The secret of its insulation lies in its continuous uniform surface and closed Honeycomb structure. The more uniform the bubble hole, the better. The three microscopic structures are white crystal plate, blue plate and Blackboard. 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.
Look at the direct pressure effect
Baijingban can not be seen by the naked eye after pressing. The good blue plate has a smaller print. The sag of the poor blue plate is obvious. The blackboard was severely damaged.
Look at life span.
The life span of a house is generally more than 50 years. Ground heating as a hidden project of the house, if it can not live with the house, it means that it will be reinstalled during use. The experiment shows that the service life of white crystal plate can reach 50 years. A good blue board can have a service life of 30 years, and a poor blue board can generally be used for 15 years. The useful life of the blackboard is generally 5 years.
Look at environmental protection.
It is recommended not to use flame retardant panels for home wear because the flame retardant HBCDD is not environmentally friendly. Baijingban is 100 % new material for environmental protection. Blue plates have certain additives. The blackboard is made of all recycled materials. Environmental protection white crystal plate & GT; Blue board & GT; The blackboard.
Look at the weight
Capacity is an important indicator of it. 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>.
