Disclosed is a continuous two-liquid type mixer comprising: a cylindrical container (10) having a liquid inlet (14) at one end and an outlet (16) at the other end; rows of stationary stirring blades (18,20) on the inside of said cylindrical container (10) protruding substantially radially on the same periphery; a rotor (22) to rotate about the same axis and housed in said cylindrical container; and rows (26) of rotary stirring blades (24) on the outside of said rotor (22) protruding substantially radially on the same periphery in an alternate relation with said rows of stationary stirring blades (18,20) on the inside of said cylindrical container, wherein at least one liquid injection inlet (28) is provided on either or both of said stirring blades on said liquid inlet side. According to the present invention, even highly viscous liquids can be mixed quickly and uniformly and troubles caused by ununiform mixing can be solved without fail.

The present invention provides a polyimide resin laminate of one layer of a polyimide resin film and one or more layers of activated fluorine resin films, wherein undulations of 0.03 - 5 µm are formed on the outer surface of said fluorine resin films. According to the present invention, the slidability of the laminate is improved, troubles in the course of taping due to poor slidability is prevented, the taping workability is markedly improved and an improved quality of polyimide laminates is provided.

For continuous production of a resin film having a plain surface, a resin solution cast in film form over an endless belt (14) is pre-hardened by a gas stream (34) supplied for flow in a direction generally parallel to the surface of the endless belt (14), and then a jet of gas is blown in the direction of movement of the endless belt whereby the resin is hardened. In the process for resin film production wherein the resin film is cast over the endless belt and then pre-hardened by a parallel gas stream, the cast film being then hardened by a jet of gas (24, 26), the installation for production is divided by partitions so as to enable various stages to be operated independently.

Disclosed is a process for continuously mixing two liquid components, one of said liquid components being a two-liquid curing type resin, which process comprises continuously supplying one liquid component under stirring into a mixing container (10) and pouring the other liquid component into said container by pushing open a needle (32) forcibly provided to a check valve (30), wherein said needle (32) is pushed open with a non-curing liquid, and thereafter a curing liquid is poured into said mixing container. According to the present invention, when, for example, a polyamide acid and a curing agent are caused to mix and react with each other, a transparent polyimide mixed uniformly is obtained and high quality molded articles of polyimide are provided therefrom.
摘要:
The present invention discloses a stirring-type mixer comprising a cylindrical container (10), a rotor (22) housed in the cylindrical container and stirring blades (18,24) attached to either of the cylindrical container or the rotor or the both, for stirring and mixing a plurality of fluid materials of different kinds fed into the aforementioned cylindrical container, while said cylindrical container and the rotor are rotated relatively, wherein a cooling means (32,36) is provided inside the aforementioned rotor and fluid materials are cooled thereby in the cylindrical container. The mixer has the capability of releasing the heat of reaction and Joule's heat out thereof and ensures against thermal deformation of the liquid material as well as shortening of its pot life.
