내셔널 구라픽 on Instagram: "공기가 액체처럼 흐르면 코팅이 된다 눈앞에서 가느다란 가루가 보글보글 끓듯 떠오릅니다. 바람을 맞은 미세한 플라스틱 가루가 바닥에서 떠올라, 마치 물처럼 흔들리죠. 달궈진 금속 기둥을 그 안에 넣는 순간, 가루가 닿자마자 녹아 표면을 감싸며 순식간에 코팅됩니다. 이 현상은 ‘유동층 코팅’입니다. 아래에서 불어오는 공기가 가벼운 분말을 떠받치면, 고체 가루가 액체처럼 움직입니다. 미리 가열된 금속이 들어가면, 분말은 접촉 즉시 녹아붙고 흘러내릴 틈도 없습니다. 금속 온도가 높을수록, 그리고 담그는 시간이 길수록 코팅은 더 두꺼워집니다. 액체처럼 움직이기 때문에 모서리와 굴곡도 빈틈없이 감싸죠. 이 방식은 울타리 기둥, 철근, 야외 구조물에 쓰입니다. 비, 염분, 충격에도 쉽게 벗겨지지 않는 이유입니다. 보이지 않는 곳에서, 공기는 이렇게 물처럼 일하고 있습니다. 과학이 싫은 이유는 재미없게 배웠기 때문이에요. 하루에 30초씩. 어느새 과학 얘기
