초록
인쇄용지에 탄산칼슘을 많이 넣을수록, 즉 고충전 인쇄용지를 만들수록 펄프섬유의 사용량이 줄어들고, 건조비용이 감소함으로 생산비는 절감되며, 온실가스의 배출량도 적어지게 된다. 현재까지 고충전 인쇄용지는 주로 중질탄산칼슘(GCC. ground calcium carbonate)에 기능성고분자를 첨가하여 적절한 크기로 선응집(pre-flocculation)시켜 사용함으로서 기존의 인쇄용지 제조방법에 비해 고충전시에도 인쇄용지의 중요한 특성들인 인장강도의 저하를 줄이고, 평활도를 유지시켜왔다. 하지만 GCC의 선응집체는 만들어진 후 사용하기까지 시간이 지체되면 그 크기와 성질이 변하는 불안정성을 보였다. 본 연구에서는 GCC의 선응집기술을 개량하여 선응집된 GCC사이에 탄산칼슘을 화학적으로 새로 생성시켜 GCC간에 연결을 시도하였으며, 그 결과 안정성이 높은 선응집체가 형성되었고, 이를 HCC (hybrid calcium carbonate)로 명명하였다. HCC는 GCC 선응집체와 같이 종이의 강도를 높이고, 평활도를 유지시켰으며, GCC 선응집체의 단점인 벌크의 저하를 역전시켜 높은 벌크를 형성시키는 장점을 보였다.
More addition of calcium carbonate in printing paper allows savings of the wood fibers and the drying energy. Pre-flocculation of GCC (ground calcium carbonate) using functional polymers was known as the best available technology to make high loaded paper until now, and it allowed less reduction of the paper essential properties such as tensile strength and smoothness at higher GCC content. However, pre-flocculated GCC became unstable in size under the continued agitation in the mill. Therefore, pre-flocculation method was modified in such a way that the in-situ calcium carbonate was formed between the GCC particles of the pre-flocculated GCC, and the resultant became more stable in size, which we named as HCC (hybrid calcium carbonate). HCC turned out to make high tensile strength and smoothness as much as the pre-flocculated GCC and gave much better size stability against stirring. Furthermore, HCC gave high bulk that pre-flocculation could not make.
