Abstract

본 발명은 하기한 일반식(I)을 갖는 탈묵제를 이용한 탈묵방법으로 종래에 비하여 잉크 입자의 포집효과가 우수하며 안정된 기포를 형성하므로 본 발명의 탈묵제를 이용하여 부상법으로 탈묵을 실시할 경우 높은 백색도의 양질의 재생 펄프를 높은 수율로 얻을 수 있을 뿐만 아니라 탈묵 후 공정, 즉 초지공정, 폐수 처리공정등에서의 기포 발생에 의한 공정상의 문제점을 최소화 할 수 있다.The present invention is a deodorizing method using a deodorizing agent having the general formula (I) as described above, which is superior to the conventional trapping effect of ink particles and forms a stable bubble, so that the desorbing method can be carried out by using the defrosting agent of the present invention. In this case, high-quality recycled pulp of high whiteness can be obtained in high yield, and process problems caused by air bubbles in the post-deoiling process, that is, papermaking process and wastewater treatment process can be minimized.
