1、通過(guò)對(duì)濟(jì)南鋁板http://www.7075lu.com/的表面字樣及內(nèi)外表層進(jìn)行觀察及觸摸進(jìn)行鑒別。正品鋁板材表面字樣一般均采用進(jìn)口噴碼打印，其字跡清晰，且商標(biāo)識(shí)別、廠家、地址甚至電話等一般標(biāo)注均較清楚、真實(shí)；假冒偽劣鋁板表面字樣多采用普通印刷機(jī)印制，字跡模糊，其廠家、標(biāo)識(shí)等一般不詳或不標(biāo)注。正品鋁板采用優(yōu)質(zhì)原料制作，其工藝精度較高，表層及內(nèi)層手感光滑順手，平整無(wú)雜斑；而偽劣鋁塑管材產(chǎn)品因偷工減料相對(duì)較差。正品鋁塑管材口及鋁帶的壁厚均勻，鋁板結(jié)合較緊密，其管材及鋁帶的質(zhì)量及厚度能達(dá)到國(guó)家有關(guān)標(biāo)準(zhǔn)；而偽劣產(chǎn)品其壁厚偏差較大，鋁片較薄，且其鋁板搭接處間隙大。
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、真鋁濟(jì)南鋁板采用超聲波搭焊方式或以氫弧焊為主對(duì)焊而成，其接口相當(dāng)緊密，明火點(diǎn)燃管材后鋁片不會(huì)出現(xiàn)脫落現(xiàn)象；而假冒偽劣的鋁塑管材及其他組合管因其鋁片無(wú)焊接，其接口不緊密，點(diǎn)燃后會(huì)出現(xiàn)鋁片脫落現(xiàn)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、將濟(jì)南鋁板http://www.7075lu.com/按螺旋狀切割成帶形，用手剝離鋁板層與PE層。真鋁塑管為5層復(fù)合結(jié)構(gòu)，其鋁層與PE層貼合較緊密，用手剝離鋁板層與PE層不易脫離；而偽劣產(chǎn)品因偷工減料，其鋁層與PE層貼合不緊密，極易剝離脫落。
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、利用小型壓力泵檢測(cè)鋁板的耐壓性能。真濟(jì)南鋁板的爆破內(nèi)壓力高，一般均能達(dá)到或超過(guò)國(guó)家有關(guān)規(guī)范的要求；而偽劣產(chǎn)品其爆破內(nèi)壓力一般較低甚至偏低，很難滿足使用要求。
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.
