    • An apparatus and method of applying a bead of TPO or TPE adhesive between a talc-free first roofing membrane and an overlapping talc-free second roofing membrane. The apparatus includes a movably supported chassis and an extruder attached to the chassis having a nozzle including an outlet having at least one opening for applying the TPO or TPE adhesive between the first membrane and the overlapping second membrane to adhere the overlapping second membrane to the first membrane. The TPO or TPE adhesive is heated within the apparatus allowing application along the seam between the first and second membranes. The outlet of the nozzle is positioned between the first and second membranes with the TPO or TPE adhesive applied between the overlapping portions of the membranes while pressing the overlapping first and second membranes to hold the overlapping portions together.
    • 在无滑石的第一屋顶膜和重叠的无滑石的第二屋顶膜之间施加TPO或TPE粘合剂珠的装置和方法。 该装置包括可移动支撑的底盘和连接到底架的挤出机,该挤出机具有喷嘴,该喷嘴包括具有至少一个开口的出口,用于在第一膜和重叠的第二膜之间施加TPO或TPE粘合剂,以将重叠的第二膜粘附到第一 膜。 在该装置内加热TPO或TPE粘合剂,允许沿着第一和第二膜之间的接缝施加。 喷嘴的出口位于第一和第二膜之间,同时将TPO或TPE粘合剂施加在膜的重叠部分之间,同时按压重叠的第一和第二膜以将重叠部分保持在一起。

    • A roofing membrane heat seal indicator provides a positive, visually perceptible indication that a joint or seam has been raised to a sufficiently high temperature to achieve a proper seal. The heat seal indicator is applied adjacent and parallel to an edge of a roofing membrane which will be arranged on a roof to form the upper (exposed) surface of an overlapping membrane seam. As the adjacent surfaces of the overlapped membranes are heated, heat passes through the membrane to the heat seal indicator. The heat seal indicator may be a temperature sensitive ink pigmented with material that changes color upon being subjected to a temperature indicating that the membrane surface has been subjected to a sufficiently high temperature to achieve an appropriate seal. Alternatively, the indicator may be an adhered layer of a ground or flaked polymer, such as polyethylene, which is initially opaque but melts to become translucent, thereby indicating obtainment of a proper sealing temperature. This indicator may be combined with a white or colored strip which enhances the change in the polyethylene. Another alternative comprehends the combination of a group indicator and molten polyethylene to form a pigmented polyethylene which is cooled, flaked, and adhered to roofing membranes. Another alternative is an embossed ridge or raised letters which may be covered with a thin, temperature sensitive polyvinyl chloride film or coating.
    • 屋顶膜热封指示器提供了正面的,视觉上可察觉的指示,即接头或接缝已经升高到足够高的温度以实现适当的密封。 加热密封指示器与屋顶膜的边缘相邻并平行地施加,屋顶膜将被布置在屋顶上以形成重叠膜缝的上部(暴露的)表面。 当重叠的膜的相邻表面被加热时,热量通过膜到热封指示器。 热封指示器可以是用受到温度变化的材料着色的温度敏感的墨水,表示膜表面已经经受足够高的温度以获得适当的密封。 或者,指示剂可以是接地或片状聚合物(例如聚乙烯)的粘附层,其最初是不透明的,但熔化成半透明的,从而指示获得适当的密封温度。 该指示剂可以与增强聚乙烯变化的白色或彩色条带结合。 另一个替代方案是组合指示剂和熔融聚乙烯的组合,以形成着色聚乙烯,其被冷却,剥落并粘附在屋顶膜上。 另一个替代方案是可以用薄的温度敏感的聚氯乙烯膜或涂层覆盖的压花脊或凸起的字母。
