Abstract
A kraft black liquor obtained from pulping of pine (Pinus densiflora Sieb et Zucc) was used for producing three kinds of adhesive such as black liquor-phenol formaldehyde resin, methyloeated kraft lignin-phenol formaldehyde resin, and lignin cake-phenol resin. In case of producing black liquor-phenol formaldehyde resin, about 60 percent of the phenolic resin could be replaced by black liquor. Also the optimal press condition appeared to be
소나무 크라프트 펄프제조과정중 회수된 폐액으로 Black liquor-phenol formaldehyde. Methylolated kraft lignin-phenol formaldehyde 및 Lignin cake-phenol rein 세 종류의 접착제가 제조되었다. Black liquor-phenol formaldehyde resin 제조시 Phenol의 약 60%를 크라프트 폐액으로 대치할 수 있다. 본 접착제의 최적압착조건은
