Abstract

A steel belt casting equipment, weighing approximately ∼6-7 tons and measuring ∼5 m in length, has been designed and developed for simulating the industrial processing of polymer films and being combined with synchrotron radiation in situ x-ray scattering measurements. Through modification of its modules, it is feasible to implement two distinct film casting modes, namely the wet and the dry casting processes. The speed of a steel belt can span from 0.5 to 8 m/min. The highest experimental temperature and drying wind speed are 300 °C and 6 m/s, respectively. All film casting parameters, such as extrusion speed, distance between die and steel belt, casting speed, temperature, and wind speed, can be adjusted independently. Especially, the control accuracy of the temperature and casting rate can reach ±0.1 °C and ±0.01 m/min, respectively. The feasibility of this equipment has been validated through in situ x-ray scattering tests at the BL10U1 industrial beamline of the Shanghai synchrotron radiation facility. With the assistance of this equipment, the understanding of the physical mechanism behind the film casting process should be improved so that the development of advanced functional polymer films.

用于现场同步辐射 X 射线散射测量聚合物薄膜的多功能钢带铸造设备。

为模拟聚合物薄膜的工业加工过程，并结合同步辐射原位 X 射线散射测量，设计和开发了一种钢带浇注设备，重约 6-7 吨，长约 5 米。通过修改模块，可以实现两种不同的薄膜浇铸模式，即湿法和干法浇铸工艺。钢带的速度可以从 0.5 米/分钟到 8 米/分钟不等。最高实验温度和干燥风速分别为 300 °C 和 6 m/s。所有薄膜浇铸参数，如挤压速度、模具与钢带之间的距离、浇铸速度、温度和风速，均可独立调节。特别是温度和浇注速度的控制精度分别可达 ±0.1 ℃ 和 ±0.01 米/分钟。通过在上海同步辐射设施 BL10U1 工业光束线进行原位 X 射线散射试验，验证了该设备的可行性。在该设备的帮助下，人们对薄膜浇铸过程背后的物理机理的认识将得到提高，从而促进先进功能聚合物薄膜的开发。
