摘要： A dope is prepared from TAC, mixed solvent and additive. The dope is cast from a casting die (31) onto a belt (34). A casting film (69) is formed on the belt (34). The casting film (69) is carried in association with movement of the belt 34. A rapid-drying blower unit (73) is disposed at a position, which is separated from a labyrinth seal (50) by 1000 mm in a downstream direction. Dry air (57) is applied to the casting film from a nozzle (73a) of the blower unit (73). Velocity of the dry air (57) is adjusted to 12 m/s. An initial film (69a) is formed on the casting film (69). The entire casting film (69) is dried after forming the initial film (69a). The casting film (69) is peeled from the belt (34) after having a self-supporting property. The casting film is heated and stretched in a tenter drier and is dried in a drying chamber.

摘要： A reducing agent removal line comprises a heat exchanger, an air supply line and a cleaning liquid supply line. The cleaning liquid supply line feeds cleaning liquid into a first passage chamber. The air supply line supplies mixed air of after-drying air containing high-melting point additive and additive containing air containing low-melting point additive into the first passage chamber. Due to contact between the mixed air and a heat-exchanging element, a mixture material containing the high-melting point additive is precipitated from the mixed air. Since melting point MP1 of the high-melting point additive in the mixed air can be controlled to be lower than a temperature of the cleaning liquid by changing a mixture ratio M, the cleaning liquid contacts and dissolves the mixture material in the mixed air.

摘要： A polymer film producing apparatus has a moving support on which dope containing polymer and solvent is cast to form a cast film. The cast film is stripped from the support to obtain a polymer film containing the solvent, and the polymer film is dried. A first gas flow duct has gas nozzles for causing a first dry gas to flow toward the cast film. A second gas flow duct has a gas outlet disposed downstream from the gas nozzles, and positioned higher than a height of the gas nozzles relative to the support, for causing a second dry gas to flow toward the cast film in a moving direction of the support. Furthermore, the first gas flow duct includes a gas blow wall for defining the first flow path by opposing to the support. The gas blow wall has the gas nozzles.

摘要： A nozzle (55b) is disposed on a bottom (55a) of an air duct (55), and a drying air (56) is fed out from a nozzle (55b) toward a casting film (69). A data of a wind speed of the drying air (56) is input on a key board (100) to a controller (58), in which a height H of the air duct (55) from a casting belt (46) is calculated from the input wind velocity V. On the basis of the calculated height H, the controller (58) drives a shift device (102) to shift the air duct (55) up- and downwardly, such that the height H may be in the range of 20 mm to 300 mm.

摘要： A dope made from TAC, additives and solvent is cast onto a belt to form a casting film. When having self-supporting property, the casting film is peeled from the belt as a wet film (120) and transported into a tenter dryer (17). The wet film (120) is stretched in its widthwise direction in a stretch area (131) and relaxed in the widthwise direction in a relaxation area (132). When a stretch rate of the width of the wet film (120) after being held for 0.1 minute is a stretch rate X (%) and a maximum relaxation rate of the width of the wet film (120) per unit time in the relaxation area (132) is a relaxation speed Y (%/min), the stretching and relaxing is performed so as to satisfy the following equation: 5X+Y
