シリコーンゴムローラが製膜フィルム表面におよぼす転写現象の解明

抄録

Rubber rollers are used in various film production processes due to their high elasticity. Among them, silicone rubber excels in heat resistance and detachability and is also used as a film-forming nip roll, taking advantage of these characteristics. However, it is extremely difficult to control the surface roughness of rubber compared to steel rollers, and the unevenness and light characteristics (transmittance) of the rubber are greatly changed by the transfer. Therefore, in this study, film formation experiments were carried out with the aim of clarifying the transfer phenomenon from the silicone rubber roller to the film formation film. Then, the transfer rate to the film was analyzed from the results of measuring the roughness of the silicone rubber surface and the film surface.
