济南铝板正品的鉴别方法

1、通过对济南铝板http://www.jngdly.com/的表面字样及内外表层进行观察及触摸进行鉴别。正品铝板材表面字样一般均采用进口喷码打印,其字迹清晰,且商标识别、厂家、地址甚至电话等一般标注均较清楚、真实;假冒伪劣铝板表面字样多采用普通印刷机印制,字迹模糊,其厂家、标识等一般不详或不标注。正品铝板采用优质原料制作,其工艺精度较高,表层及内层手感光滑顺手,平整无杂斑;而伪劣铝塑管材产品因偷工减料相对较差。正品铝塑管材口及铝带的壁厚均匀,铝板结合较紧密,其管材及铝带的质量及厚度能达到国家有关标准;而伪劣产品其壁厚偏差较大,铝片较薄,且其铝板搭接处间隙大。
Through the words of Jinan aluminum surface and the inner and outer surface were observed and touch were identified. Genuine aluminum sheet surface words are generally imported Coding print, its clear writing, and identifying trademark,manufacturer, address or telephone and other general than those clearly marked, true; words more fake aluminum surfaces using ordinary printing presses, illegible its manufacturer, logo, etc. are generally unknown or not marked. Genuine aluminum using high quality raw materials production, its high technology precision, feel smooth inner surface and easily, smooth and no clutter; and shoddy plastic pipe products due to the relatively poor cut corners. Genuine aluminum pipe wall thickness uniformity of the mouth and aluminum, aluminum combine more closely, the quality and thickness of the pipe and aluminum can reach the national standard; and shoddy products wall thickness deviation is large, thin aluminum and its aluminum lap large gap.
  
2、真铝济南铝板采用超声波搭焊方式或以氢弧焊为主对焊而成,其接口相当紧密,明火点燃管材后铝片不会出现脱落现象;而假冒伪劣的铝塑管材及其他组合管因其铝片无焊接,其接口不紧密,点燃后会出现铝片脱落现象。
Al Jinan really take aluminum ultrasonic welding or by hydrogen arc welding mainly from its interface is quite close, the aluminum off phenomenon does not occur after the fire lit the pipe; and fake plastic pipes and tubes due to other combinations its aluminum-free solder, the interface does not close, there will be lit aluminum shedding phenomenon.
  
3、将济南铝板http://www.jngdly.com/按螺旋状切割成带形,用手剥离铝板层与PE层。真铝塑管为5层复合结构,其铝层与PE层贴合较紧密,用手剥离铝板层与PE层不易脱离;而伪劣产品因偷工减料,其铝层与PE层贴合不紧密,极易剥离脱落。
The Jinan-shaped aluminum plate with a spiral cut, hand stripping aluminum layer and PE layer. True aluminum tubes for 5-layer composite structure, its aluminum layer and PE layer bonded more closely, hand stripping aluminum layer and PE layer easy detachment; and shoddy products because of shoddy work, the aluminum layer and the PE layer does not fit tightly, very easy to peel off.

4、利用小型压力泵检测铝板的耐压性能。真济南铝板的爆破内压力高,一般均能达到或超过国家有关规范的要求;而伪劣产品其爆破内压力一般较低甚至偏低,很难满足使用要求。
The use of small pressure pump pressure detection performance of the aluminum plate. Jinan aluminum within the true burst pressure is high, generally can meet or exceed the state standards requirements; and shoddy products within its burst pressure is generally low and even lower, it is difficult to meet the requirements.
