1、橫向抗拉強度
1. Transverse tensile strength
冬夏兩季使用時,組成隔熱鋁窗的隔熱型材里、外兩腔型材之間存在很大的溫度差異,這種溫差會使里、外兩腔鋁材之間產生不同的變形趨勢.夏季時,外腔型材溫度高,造成外拱內縮.冬季時,外腔型材溫度低,造成內拱外縮,這種不停的拱曲應力會使隔熱型材產生中部較大的橫向拉力.若隔熱條的橫向抗拉強度低,就會發生斷裂,導致隔熱型材出現質量問題.
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 deformation 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.

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 deformation. The greater the value is, the smaller the elastic deformation is produced under the same stress, the more rigid the material is.
3、沖擊強度
3. Impact strength
當產品經受動載荷時,需要材料的沖擊強度(韌性)性能指標,沖擊強度的高低也說明材料的韌性性能,是選材的性能指標之一,好的韌性可以保證隔熱條在裝配時具有比較高的成品率.
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.
