粘(zhan)(zhan)性是指流體內部(bu)由于內摩(mo)擦作用(yong)而阻礙其(qi)相對流動的(de)一種特征，以粘(zhan)(zhan)度來(lai)表示其(qi)大(da)小（作用(yong)于1單位(wei)面積的(de)內摩(mo)擦力），單位(wei)是Pa·s。粘(zhan)(zhan)度的(de)測定(ding)，一般(ban)采用(yong)旋轉粘(zhan)(zhan)度計，以在含70%固含量的(de)高(gao)嶺(ling)土泥(ni)漿(jiang)中的(de)轉速(su)來(lai)衡量。在生產工藝中，粘(zhan)(zhan)度具有重要意義，它不僅是陶瓷工業的(de)重要參數(shu)，對造紙(zhi)工業影響也(ye)很大(da)。據資料表明(ming)，國(guo)外用(yong)高(gao)嶺(ling)土作涂料，在低速(su)涂布時(shi)要求粘(zhan)(zhan)度約0.5Pa·s，高(gao)速(su)涂布時(shi)要求小于1.5Pa·s。
