断桥铝门窗生产方式
Production mode of broken bridge aluminum doors and windows
隔热型材的生产方式主要有两种，一种是采用隔热条材料与铝型材，通过机械开齿、穿条、滚压等工序形成"隔热桥"，称为隔热型材"穿条式";另一种是把隔热材料浇注入铝合金型材的隔热腔体内，经过固化，去除断桥金属等工序形成"隔热桥"，称为"浇注式"隔热型材。
There are two main production methods of thermal insulation profile: one is to use thermal insulation strip material and aluminum profile to form "thermal insulation bridge" through mechanical tooth opening, threading, rolling and other processes, which is called "threading type"; the other is to pour the thermal insulation material into the thermal insulation cavity of aluminum alloy profile, and then to form "thermal insulation bridge" after solidifying, removing the broken bridge metal and other processes, which is called "pouring type" thermal insulation profile 。
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、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 the thermal insulation profile can be profiles with different sections or profiles with different colors with different surface treatment methods. However, due to the influence of region and climate, to avoid the large gap between thermal insulation materials and aluminum profiles due to the large linear expansion coefficient, there will be a large stress and gap between them during thermal expansion and cold contraction; at the same time, thermal insulation materials and aluminum profiles are combined into a whole, and in the structure of doors and windows and curtain walls, they are also stressed as aluminum. Therefore, it is required that the thermal insulation material must have the tensile strength, bending strength, expansion coefficient and elastic modulus close to the aluminum alloy profile, otherwise the thermal insulation bridge will be disconnected and damaged. Therefore, the selection of thermal insulation materials is very important.
