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.
一种钢带铸造设备，重约6 - 7吨，长约5米，已被设计和开发用于模拟聚合物薄膜的工业加工，并与同步辐射原位X射线散射测量相结合。通过对其模块的改进，可以实现两种不同的薄膜铸造模式，即湿法和干法铸造工艺。钢带速度范围为0.5至8米/分钟。最高实验温度和干燥风速分别为300°C和6米/秒。所有薄膜铸造参数，如挤出速度、模头与钢带之间的距离、铸造速度、温度和风速，均可独立调节。特别是，温度和铸造速率的控制精度分别可达±0.1°C和±0.01米/分钟。该设备的可行性已通过在上海同步辐射装置的BL10U1工业光束线进行的原位X射线散射测试得到验证。借助该设备，应能增进对薄膜铸造过程背后物理机制的理解，从而推动先进功能聚合物薄膜的发展。
