铝合金门窗设备产品共有的机械性能

1、横向抗拉强度
1. Transverse tensile strength
冬夏两季使用时,组成隔热铝窗的隔热型材里、外两腔型材之间存在很大的温度差异,这种温差会使里、外两腔铝材之间产生不同的变形趋势.夏季时,外腔型材温度高,造成外拱内缩.冬季时,外腔型材温度低,造成内拱外缩,这种不停的拱曲应力会使隔热型材产生中部较大的横向拉力.若隔热条的横向抗拉强度低,就会发生断裂,导致隔热型材出现质量问题.
In the two quarter of winter and summer, there is a great difference in temperature between the inside and outside two cavities of insulated aluminum windows, which will cause different deion trends between the two lumber of the inner and outer chamber. In summer, the outer cavity profile is high in temperature and causes the inner contraction of the outer arch. In winter, the outer cavity profile is low in temperature and causes the inner arch to shrink, this ceaselessly The arch stress will cause the large transverse tension in the middle part of the heat insulation section. If the transverse tensile strength of the heat insulation strip is low, the fracture will occur, which leads to the quality problems of the insulation profiles.
2、纵向抗拉强度及弹性模量
2, longitudinal tensile strength and modulus of elasticity

纵向抗拉强度体现了隔热条在纵向上的力学性能,同时弹性模量是最能表征材料使用性能的指标之一,在工程上,弹性模量被称为材料的刚度,它表征材料对弹性变形的抗力,其值越大,则在相同应力下产生的弹性变形越小,材料越刚.

The longitudinal tensile strength reflects the longitudinal mechanical properties of the heat insulation strip. At the same time, the modulus of elasticity is one of the most capable of characterizing the performance of the material. In engineering, the modulus of elasticity is called the stiffness of the material. It characterizes the resistance of the material to the elastic deion. The greater the value is, the smaller the elastic deion is produced under the same stress, the more rigid the material is.
3、冲击强度
3. Impact strength
当产品经受动载荷时,需要材料的冲击强度(韧性)性能指标,冲击强度的高低也说明材料的韧性性能,是选材的性能指标之一,好的韧性可以保证隔热条在装配时具有比较高的成品率.
When the product is subjected to the load, the impact strength (toughness) performance index of the material is required. The impact strength also indicates the toughness of the material. It is one of the performance indexes of the material. The good toughness can guarantee the high yield of the heat insulation strip in the assembly.
