  • 怎麼區分擠塑闆的好與壞?

一、看原料


原料是擠塑闆環保性能的關鍵因素。擠塑闆是由聚苯乙烯樹脂生産而成。但是現在市場上的很多擠塑闆是由回收料制作而成的。市面上還有紅色和黃色的擠塑闆一般和藍色的擠塑闆差不多。下面三種分别是巴斯夫水晶原料、高級回收聚苯乙烯、回收聚苯乙烯。

二、看微觀結構


擠塑闆的主要用途之一就是作為地暖保溫層使用。擠塑闆保溫的秘訣在于他的連續均勻表層及閉孔式蜂窩結構。泡孔越是均勻越好。下面是四種擠塑闆的微觀結構圖。白晶闆的泡孔均勻且封閉。藍闆泡孔封閉良好。黑闆沒有泡孔基本沒有封閉。

三、看導熱系數


導熱系數越低意味着阻熱保溫效果越好。

四、看容重


容重是擠塑闆的一個重要指标。直接和抗壓性能挂鈎。地暖用白晶闆的容重一是35到36KG/m³。好的藍闆的容重也是這個值。但是由于藍闆的原料的問題即使容重一樣,白晶闆的質量還是要比藍闆好。差一點的藍闆的容重是30KG/m³左右。黑闆的容重一般是在25KG/m³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>.
