TH75167B - Coating process to base material - Google Patents

Abstract

DC60 (05/03/56) The coating process leads to a base material that can be beautifully coated with some membranes. High speed in the time when using roll coaters for multi-layer coating liquid coatings running base materials. continuously When the multilayer coating liquid is fed into the rolling applicator rotated by the diecoater, and thereafter Makes the application roll in contact with the base material that runs continuously and transfers the Multi-layer coating liquid applied to the base material. The applicator roll rotates in the reverse direction with the base material being part in contact with base material and the multi-layer coating liquid fed by the die-cotter the specified case Let the viscosity coefficient of the coating liquid forming the bottom layer on the application roll be mu 1 and the coefficient of viscosity of the coating liquid forming the top layer mu 2 will be become more mu1 than mu2 and the remaining multilayer coating liquid at application rolls without being transferred to the material The base will then be eliminated from the application roll.

Claims (1)

1. The coating process to the base material is characterized by the time the coating liquid is fed. Multiple layers to an applicator rotated by a die coater. and after that make the app roll loud In contact with the running base material and transferring the multi-step coating liquid to the base material, the application roll rotates in the reverse direction with the base material at the contact with the base material and the liquid. The multilayer coating fed by the die coater is In the event that the coefficient of The viscosity of the coating fluid forming the bottom layer on such an application roll is u1 and the viscosity coefficient of the coating fluid forming the bottom layer as u2 becomes u1.
