Thixotropy occurs in paint, such as lithopone in oil, which flows freely when stirred and reverts to a gel-like state on standing. Quicksand, a mixture of sand and water, is rendered thixotropic by the presence of certain clays. Drilling mud, made thixotropic by the inclusion of bentonite, forms a cake on the wall of the drill hole to keep drilling fluid in the hole and to prevent outside water from entering. from Britannica 젤 상태에서 흩뜨려졌을 때 원형으로 바뀌는 현상을 지칭하는 것 같죠. 이때 되돌아 올때는 응력곡선이 소성변형전과는 다른 곡선을 가지게 되겠죠. 이상 전공자가 아닌 대답이었습니다. rheology 쪽 전공 같은데요. |
