摘要： A dope containing a TAC and solvent is prepared in a dope producing apparatus. In a case where a new dope having components different from that of the dope described above is produced, a controlling device performs controlling such that an operation of each pump is stopped, each valve is set to a closing position, and a hopper stops supplying the TAC. Thereafter, a washing liquid is introduced into the respective devices of the dope producing apparatus. The dope remained in the respective devices are discharged as a waste liquid together with the washing liquid. The waste liquid is heated in dry gas until a liquid level of the waste liquid turns into a falling-rate drying state in a dry heating chamber provided in a solvent removing device. In a wet heating chamber, the waste liquid is heated in wet gas.

摘要： The solution film-forming method is provided in which the absolute filtration accuracy for a cellulose acylat solution can be improved and filtration throughput can be increased without reducing the pore size of a filtering material. A dope stock solution to be filtrated is first introduced into a body feed tank and a filter aid from a filter aid tank is added and dispersed. As the filter aid, an aid including SiO2 in 50% or more and a cellulose-based aid are mixed for use. The dope stock solution in which the filter aid is dispersed is introduced into a filter machine and subjected to filtration while forming a cake on the surface of the filtering material. After the filtration, a cleaning solvent is supplied in circulation from a cleaning solvent tank, and the cake is discharged as slurry. The filter aid is separated from the slurry by a separating device and burned in a burning device. Then, a regenerated filter aid is sent to the filter aid tank. After the cleaning, a precoat liquid in which the filter aid is dispersed is supplied from a precoat tank to the filter machine to form a precoat layer on the surface of the filtering material.

摘要： A casting dope is cast onto a moving peripheral surface to form a casting film. The casting film is cooled to be hardened or solidified. The casting film is peeled from the peripheral surface by a peeling roller to form a primary wet film. The primary wet film is transported to a transfer section. The primary wet film is sent from the transfer section to a first drying chamber. Wet gas containing water vapor is applied to the primary wet film in the first drying chamber. Water molecules are absorbed into the primary wet film. The water molecules absorbed into the primary wet film expand meshes of network structure of polymer molecules of the primary wet film. The diffusion of liquid compounds contained in the primary wet film is accelerated. Thus, the elimination of the liquid compounds can be facilitated.

摘要： A stock solution is prepared by mixing and swelling TAC as a solute in a solvent, and is fed into an extrusion machine. The extrusion machine is cooled by a cooling medium, and is provided with twin-shaft screws. The screws are a compressing type where thread pitches of a helical flight decrease toward downstream. The screws are in mesh with each other and rotated in the same direction. Through the extrusion machine, the solute is dissolved in the solvent to form a dope. The dope is further cooled in a cooler to promote the solubility of the dope. Thereafter, the dope is heated by a heater to raise the fluidity. From the obtained dope, TAC film with excellent optical properties may be formed by a solution casting method.

摘要： A dope (15) is prepared with using TAC as a polymer. The dope (15) is transferred with heated by a transferring device (30). A heating medium (36) is used to heat the dope in the transferring device (30). A passage (35) for the heating medium (36) is formed between a cylinder (31) and a jacket (34). The jacket (34) is attached to flanges (32), (33) so as to form a full jacket. When the heating medium (36) is fed in the full jacket, a temperature of the flanges (32), (33) becomes equal to a temperature of the cylinder (31). Accordingly, temperature profile of the dope (15) becomes small, because there is no low temperature portion in the transferring device (30). Therefore, gelatinous material, which is caused by association generated on the low temperature portion, is not in the dope (15).
摘要翻译：使用TAC作为聚合物制备涂料（15）。掺杂物（15）由转移装置（30）加热转移。加热介质（36）用于加热转印装置（30）中的涂料。用于加热介质（36）的通道（35）形成在气缸（31）和夹套（34）之间。夹套（34）附接到凸缘（32），（33）以形成全套。当加热介质（36）进料到全套管中时，凸缘（32），（33）的温度变得等于气缸（31）的温度。因此，由于转印装置（30）中没有低温部分，所以涂料（15）的温度分布变小。因此，在低温部分产生的缔合引起的凝胶状材料不在涂料（15）中。

摘要： A solvent and TAC particles are continuously supplied to a disperser. When the shearing of the solvent and the particles are made in a shearing section, the particles are dispersed in the solvent. The dispersion is fed to a mixer in one minute. The shearing of the dispersion is made in the mixer, the particles are swollen in the solvent in one minute. Since the shearing and the continuous feed of the swelling solution is made, the aggregation does not occur. There are no undissolved aggregates in a dope, which is obtained from the swelling solution. A film produced from the dope has no defects of luminescent spot but excellent optical properties.
