擠塑闆是一種由聚苯乙烯泡沫塑料制成的有保溫性能的闆材,以優良的保溫、抗壓性能、高熱阻、低線性、膨脹比低、憎水性、防潮性等特點而被廣泛用于現在的很多外牆建築。相信很多建築行業都有在使用這種闆材,所以下面杭州博恩環保科技有限公司帶我們一起來學習一下它的選購技巧,通過其使用的初始關卡。

  一、看原材料:現在市面上銷售的擠塑闆,一般有三種顔色,分别是:白色,藍色,黑色。每種顔色的原材料來源不同,白色的擠塑闆,它是由聚苯乙烯樹脂生産而成。而藍色的以及黑色的就有可能是由回收的材料制成的,所以在選購的的時候選顔色越淺的越好。

  二、看泡孔:泡孔是決定擠塑闆保溫性能優劣的關鍵因數,所以在選購時我們要觀察它的表層及泡孔是否連續均勻。泡孔越是均勻保溫性就越好。一般白色闆的泡孔均勻且封閉,藍闆闆泡孔封閉良好,黑闆闆沒有泡孔基本沒有封閉。

  三、看外力擠壓:高品質的闆,在外力的擠壓下會産生可恢複的形變或是凹陷,而劣質的就會産生難以恢複的形變和凹陷。一般白色闆經按壓後肉眼基本看不出來,藍色闆有較小的印,而黑色闆就會産生非常明顯的凹陷。

  四、看保溫級别:我們在選購的時候,要先去看看它的保溫級别。一般來說,需要選擇B1級的擠塑闆。它是近年普遍推廣應用的新型建築材料,這種利用廢舊塑料變廢為寶的新型環保材料,具備了相當優良的性能。

  五、看厚度:查看闆厚度,根據不同要求來選擇不同厚度的闆。通常,用戶可以選擇2-10公分厚的産品。

  六、看檢驗标準:需要檢查擠塑闆的一些标準。相關規定中,擠塑闆的低标準阻燃要求為B2級,它的氧指數要≥26。在擠塑闆生産過程中一定要添加阻燃劑,所以可以查看它的組成成分,以此來判定選購的擠塑闆是否具有阻燃效果。

  以上就是我們選購擠塑闆産品可以利用的技巧介紹。随着現在各行各業的經濟發展壯大,投機取巧的商家随之産生,我們要想避免上當受騙,就要掌握很多辨識産品質量的方法,才能免花冤枉錢。

The extruded sheet is a sheet made of polystyrene foam with thermal insulation properties. It is widely used in many external walls today with excellent thermal insulation, compressive performance, high thermal resistance, low linearity, low expansion ratio, hydrophobicity, and moisture resistance. building. It is believed that many construction industries are using this kind of sheet metal, so the following Hangzhou Boen Environmental Technology Co., Ltd. takes us to learn its purchasing skills and use the initial level.
First, look at the raw materials: the extruded plastic plates now on the market, generally have three colors, namely: white, blue, black. The source of raw materials for each color is different. The White extruder board is made of polystyrene resin. Blue and black may be made from recycled materials, so the lighter the color, the better.
Second, look at the bubble hole: bubble hole is the key factor that determines the insulation performance of the extruding board, so when we buy it, we must observe whether the surface layer and bubble hole are continuous and uniform. The more uniform the bubble hole, the better the insulation. Generally, the bubble holes of the white plate are uniform and closed, and the blue plate bubble holes are closed well. The blackboard board has no bubble holes and is basically not closed.
Third, look at external forces extrusion: high-quality plates, under the pressure of external forces will produce recoverable deformation or depression, and inferior will produce difficult to restore deformation and depression. In general, the white plate can not be seen by the naked eye after pressing. The blue plate has a smaller print, and the black plate will produce a very obvious depression.
Fourth, look at the insulation level: when we buy, we must first go to see its insulation level. In general, you need to select a B1 extruding board. It is a new type of building material that has been widely promoted and applied in recent years. This new type of environmental protection material that uses waste plastics to become a treasure has excellent performance.
Look at the thickness: the thickness of the board, according to different requirements to choose different thickness of the board. In general, users can choose 2-10 cm thick products.
Look at the inspection standards: some standards need to be checked for extruding plastic plates. In the relevant regulations, the low standard flame retardant requirement of the extruded plastic plate is B2, and its oxygen index is ≥ 26. It is necessary to add flame retardant in the production process of extruding board, so you can check its composition to determine whether the extruding board purchased has flame retardant effect.
The above is our selection of extruding board products can use the skills introduced. With the growth of economic development in all walks of life, opportunistic businesses have emerged. If we want to avoid being deceived, we must master many methods to identify the quality of products in order to avoid spending money.
