sheet manufacturing apparatus and method , and barrier coated paper containing the barrier coating process

摘要

PURPOSE: A manufacturing device of base paper being environmentally friendly is characterized by using water dispersible barrier coating chemicals, containing a barrier coating process, dissociating the base paper in a pulper when the base paper is reused and producing the base paper having proper size. The manufacturing device thereof is capable of reducing production cost, increasing productivity and preventing loss of the base paper. CONSTITUTION: A manufacturing device of base paper contains a composing process(10), a first paper making process(20), a coating process(100) and a second paper making process(40). A coating device coating a surface and a back of the base paper(P) by using many coating stations comprises: a barrier coating part(200) coating one side of the base paper with a barrier coating chemicals; a first drying part(210) drying the coated base paper; a pre-color coating part(220) coating the dried base paper with pre-color; a second drying part(230) drying the coated base paper; a top-color coating part(240) coating the base paper with top-color; and a third drying part(250) drying the coated base paper. The coating process comprises: a barrier coating process; a barrier coating drying process; a pre-color coating process; a pre-color drying process; a top-color coating process; and a top-color drying process.
