Title:
METHOD FOR DIP-COATING GRAPHITE PROCESSED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/238979
Kind Code:
A1
Abstract:
The present invention pertains to a method for dip-coating a graphite processed product. More specifically, the present invention pertains to a method for forming a high-quality carbonized surface by minimizing surface defects caused by a dipping resin during the curing of a graphite processed product. In particular, the purpose of the present invention is to provide a method for dip-coating a graphite processed product, wherein a high-pressure gas in an inert atmosphere such as nitrogen is introduced to suppress the evaporation of a dipping solution and allow curing to occur in a state in which the dipping solution is retained inside pores. In particular, according to the present invention, dipping is performed under high-pressure conditions in an inert atmosphere and a dipping solution (phenolic resin) is forcibly injected deep into the pores of a graphite processed product through gas pressure to minimize the surface porosity of the graphite processed product, thus having the effect of making is possible to form a uniform and pore-free carbonized surface.
