驱动器的作用是驱动伸缩门在不停的旋转和运转中，实现电动伸缩门的智能控制功能。（一）门体1、门体分为钢化玻璃和铝合金两种，钢化玻璃是指以聚氯乙烯树脂为主要原材料，使用高分子复合材料，制成不同厚度、不同形状的发泡玻璃。2、门体选用优质钢化钢材，制成不同厚度、不同形状的发泡玻璃。优质的钢化玻璃外表亮丽、耐用，耐腐蚀，能长时间承受高温和高湿。装饰玻璃是经过热熔工艺制成的。

LOW-E中空玻璃是一种良好的隔热、隔音、美观适用、并可降低建筑物自重的新型建筑材料，它是用两片（或三片）玻璃，使用高强度高气密性复合粘结剂，将LOW-E玻璃片与内含干燥剂的铝合金框架粘结，制成的高效能隔音隔热玻璃。

LOW-E hollow glass is a new type of building material with good heat insulation, sound insulation, beauty and application, and can reduce the weight of building. It is a high efficiency insulation glass insulation glass made of two pieces (or three pieces) of glass with high strength and high air tightness compound binder, which is bonded with the aluminum alloy frame frame containing the desiccant. Glass.
