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.
RCOO(CH2CH2O)mH (I)RCOO (CH 2 CH 2 O) m H (I)
상기 식에서, m은 10∼18인 실수이고, R은 이중 결합을 포함하지 않거나 1∼3개를 포함하는 탄소수 9∼19인 알킬기이고, m에 가장 가까운 정수가 n일때 n몰 또는 n ±1몰의 에틸렌옥사이드가 부가된 화합물의 함량이 50% 이상이다.Wherein m is a real number of 10 to 18, R is an alkyl group having 9 to 19 carbon atoms that does not contain a double bond or contains 1 to 3, and n mole or n ± 1 mole when the integer closest to m is n The content of the compound to which ethylene oxide is added is 50% or more.
