TH135649A - Coating process to base material - Google Patents

Abstract

DC60 (05/03/56) A coating treatment to base material that can be beautifully applied with a thin membrane. High speed in roller coats of multilayer liquid coatings, running base materials Continuously When the multi-layer coating liquid is fed into the applicator roll rotated by the diecotter and then Make the applicator roll in contact with the base material running continuously and transfer of The liquid is applied several layers to the base material. The applicator rotates in the reverse direction with the base material. The part in contact with the base material And the multi-layer coating liquid fed by the decoder If specified Let the coefficient of the viscosity of the top layer forming coating fluid in mu 1 and the coefficient of the viscosity of the top layer forming coating fluid in mu 2, then Becomes mu 1 rather than mu 2 and the remaining multi-layer coating liquid at The applicator rolls without being transferred to the material. The base is then wiped out from the applicator.

Claims (1)

1. The process of applying the coating to the base material has a specific characteristic, that is, when the coating liquid is fed Multiple layers to the applicationter rotating by the cotter. And after that Make the apparatus roll loud When it comes in contact with a continuous running base material and transfers the multilayer coating fluid to the base material, the applicator rolls rotate in reverse direction with the base material in contact with the base material and the liquid. The multi-layer coatings that were fed by the diecotter are If the coefficient of The viscosity of the top-forming coating fluid on the such applicator is u1, and the coefficient of the viscosity of the top-forming coating fluid u2 becomes u1 <U2 &NBSP; and &NBSP; p is removed from the applicator roll. <The residual multilayer coating fluid on the applicator roll is not transferred to the base material>
