| 隔热型材的内外两面，可以是不同断面的型材，也可以是不同表面处理方式的不同颜色型材。但受地域，气候的影响，避免因隔热材料和铝型材的线膨胀系数的差距很大，在热胀冷缩时二者之间产生较大应力和间隙;同时隔热材料和铝型材组合成一体，在门窗和幕墙结构中，同样和铝材一样受力。因此，要求隔热材料还必须有与铝合金型材相接近的抗拉强度橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子 、抗弯强度，膨胀系数和弹性模量，否则就会使隔热桥遭到断开和破坏。因此，隔热材料的选用是非常重要的。 The inner and outer sides of heat insulation profiles can be profiles of different sections or profiles of different colors with different surface treatments. However, due to the influence of region and climate, it is avoided that the linear expansion coefficient of insulation materials and aluminium profiles differs greatly, resulting in greater stress and clearance between them during thermal expansion and cold contraction. At the same time, thermal insulation materials and aluminium profiles are combined into a whole, and they are also subjected to the same force as aluminium profiles in doors, windows and curtain walls. Therefore, it is required that the insulation material must have the similar tensile strength, flexural strength, expansion coefficient and elastic modulus to the aluminum alloy profile, otherwise the insulation bridge will be broken and destroyed. Therefore, the selection of insulation materials is very important |
