    摘要: 流變學是研究測試物品流動行為與變形行為。它的應用非常之廣泛,有很多的產品運送過程的成功與失敗都和流變性質有很重要的關係,不論是在食品業、化學工業、化粧品產業、生物技術業、材料科學應用以及醫藥業影響甚距。下一段本研究藉由流變儀測試六種植物油以及市售的五種沐浴乳、五種洗髮精、五種洗碗精、五種乳液、五種護手霜、五種粉底液,探討不同產品在變化不同剪切速率及應力,比較其流變特性。第一部分油脂測試黏度性質結果大多為牛頓流體,只有棕櫚油是剪切稀化,不同比例的橄欖棕櫚混合油,比例橄欖棕櫚油1:5和橄欖棕櫚油1:3也是呈現高黏度的剪切稀化。第二部份洗劑測試剪切速率,洗髮精一致都是剪切稀化;沐浴乳因為成分複雜但仍是剪切稀化的流體;洗碗精在較高應力時顯示為牛頓流體。第三部分乳液測試、護手霜、粉底液因成分複雜剪切速率皆是剪切稀化。
    Rheology is a study on the flow behavior and deformation behavior of test items. Its application is very wide, there are a lot of product delivery process of success and failure and rheological nature has a very important relationship, whether in the food industry, chemical industry, cosmetics industry, biotechnology industry, materials science and medicine industry Affect the distance.The next section of this study by the rheometer test include six kinds of vegetable oil and five kinds of body wash, five kinds of shampoo, five kinds of dishwashing, five kinds of lotion, five kinds of hand cream, five liquid foundation, Different products in varying the shear rate and stress, compared with its rheological properties.The first part of the vegetable oil viscosity test properties of the results mostly Newton fluid, only palm oil is shear thinning, different proportions of olive palm mixed oil, the proportion of olive palm oil 1: 5 and olive palm oil 1: 3 is also showing high viscosity shear Thinning. The second part of the lotion shear rate test, shampoo are consistent shear thinning; because body wash composition is complex so it shows up shear thinning fluid; dishwashing at higher stress when the Newton fluid. The third part of the lotion test, hand cream, liquid foundation for the composition of complex shear rate are shear thinning.
