花纹铝卷是我们经常使用的产品，然而有些用户购买的花纹铝卷脆是怎么回事?其实，铝卷脆主要是由于一些铝卷生产厂家生产技术原因，生产工艺不达标，天然输出的装饰铝卷很容易出现脆化现象，

    具体原因主要集中在以下三个方面:
    Thespecificreasonsaremainlyconcentratedinthefollowingthreeaspects:

    1.模具截面设计不合理:内部配筋和界面角度分布不当会导致应力集中现象的存在，导致铝脆卷曲图案，需要改进设计，消除界面的直角和锐角。
 1.Unreasonabledesignofdiesection:improperdistributionofinternalreinforcementandinterfaceanglewillleadtotheexistenceofstressconcentration,resultinginthecrispyandcurlypatternofaluminum,soitisnecessarytoimprovethedesignandeliminatetherightangleandacuteangleofinterface.
    2.模具压头压力不足:模具压头的压力直接由模具的压缩比决定，尤其是模具的直线段长度。压头的压缩比过小或平截面过短都会造成产品不致密，影响铝盘管的物理性能。
 2.Insufficientpressureofdiehead:thepressureofdieheadisdirectlydeterminedbythecompressionratioofdie,especiallythelengthofstraightsectionofdie.Ifthecompressionratiooftheheadistoosmallortheflatsectionistooshort,theproductwillnotbecompact,whichwillaffectthephysicalpropertiesofthealuminumcoil.
    三。分流杆遇到坏:在这种情况下,应适当增加肌肉和外表面强化和钢筋长度的融合,或增加压缩比,模头压力的变化可以调节长度变化的连续模头流阻,在模具设计阶段选择不同的压缩比可以改变挤压压力,但注意鼻子挤出机螺杆压缩比压缩比,还可以通过改变配方,调整挤出工艺参数，增加穿孔板，改变熔体压力大小。

    上述模式铝盘管产品常见的脆弱的原因,当用户购买产品时,必须选择那些信誉高的铝卷生产厂家,企业的实力购买自己的产品,为了避免因为购买产品的质量不符合标准,并推迟了他们的正常生产。
