摘要:
The present invention relates to an injection machine comprising: a heating barrel which heats a powder material, a binder, and a resin material into a molten resin; a screw mounted in the heating barrel to mix the resin material; and a motor which drives the screw in rotation. The injection machine according to the present invention further comprises a through-hole disposed on a side surface of the heating barrel; a pipe in which a solvent for adjusting a viscosity of the resin material is conducted, the pipe being connected to the through-hole; a filter disposed in the through-hole to prevent the resin material from leaking to the pipe; a valve disposed midway on a pipeline of the pipe; a reservoir disposed on an end of the pipeline of the pipe; a load-detecting part which detects a load value of the motor; a controlling part which sets a reference value with respect to a load of the motor; and a driving part which compares the detected load value with the reference value to drive the valve to carry out either one of supply or discharge of the solvent.
摘要:
A PVA film successively oriented in two orthogonal directions is prepared by firstly elongating the film in the longitudinal direction by more than 200% while maintaining the water content (Z .times. 100)% at a value of from 10 to 35% and the temperature in a range of from (1.50/Z +20).degree. C to 75.degree. C. The film is then preheated while maintaining its water content at least 7%, and then elongated laterally by more than 200% at a temperature of from 45.degree. to 110.degree. C. Then the film is heat treated at a temperature of 110.degree. to 210.degree. C while permitting the film to shrink by less than 15% in the lateral direction. Finally, the film is cooled to room temperature under tension.
