合肥彩钢板浅谈EPS彩钢夹芯板质量问题

发布时间:2016-8-8 10:48:45 浏览次数:483

在质量问题上,EPS彩钢夹芯板最易在黏结强度、面密度、剥离性能、尺寸偏差等方面出现问题。黏结强度差导致夹芯板不能承受足够外力,很容易损坏,易被撕裂。夹芯板在实际安装过程中,不能承受足够机械力;面密度差这将导致夹芯板的抗弯性能不足,不能承受压力。


On the quality problems, EPS sandwich panel the problems in the bonding strength, surface density, peeling performance, size deviation. Poor bonding strength leads to the sandwich panel can not bear enough external force, it is easy to damage, easy to tear. Sandwich panel in the actual installation process, can not afford enough mechanical strength, surface density difference this will lead to the sandwich panel bending performance is insufficient, can not withstand the pressure.


例如用在屋顶上夹芯板,不慎被加上重物,则容易造成室内人身伤害,用在轻型组合房屋的围护结构经不住较大推力,稳定性差。其实只要生产厂家按JC689.1998{金属面聚苯乙烯夹芯板》标准组织原料生产,面密度这个指标非常容易达到。


For example, in the roof of the sandwich panel, accidentally added weight, it is easy to cause damage to the body, in light of the building envelope can not live a larger thrust, stability is poor. In fact, as long as the manufacturers press JC689.1998{metal polystyrene sandwich plate, the standard organization of raw materials production, the surface density of this index is very easy to achieve.


如果剥离性能差会导致用夹芯板保温的冷库的使用寿命将达不到设计要求,消费者的经济利益受到严重伤害。尺寸偏差会使规格变小,使用方用量增加,增加建设成本。标准对长度、宽度、厚度的偏差都是有规定的,许多企业对标准不理解,所报产品规格型号与实际生产有较大出入。


If the stripping performance is poor, the service life of the cold storage with sandwich panels will not reach the design requirements, and the economic benefits of consumers will be seriously injured. Size deviation will make the size smaller, the use of the use of the increase in the cost of construction. Standard for length, width, thickness of the deviation are provided, many companies do not understand the standard, the reported product specifications and the actual production has a greater access.


如标准规定的宽度系列为1150mm、1200mm,允许偏差±2mm。,而有的厂家将1150mm规格报成l200mm。此外有的厂家由于设备下料精度的不足等原因,也易造成尺寸偏差不合格。


Such as the standard width of a series of 1150mm, 1200mm, allowing the deviation of + 2mm. , and some manufacturers will 1150mm specifications reported as l200mm. In addition, some manufacturers due to the lack of equipment under the material accuracy and other reasons, but also easy to cause the size of the deviation is not qualified.
