一.定義Definition：

休止角是指粉體堆積層的自由斜面在靜止的平衡狀態(tài)下，與水平面所形成的角

theangle of repose is the maximum angle formed between the free slope of thepowder accumulation under static equilibrium state and horizontal plane.

二.工作原理principle：

休止角常用的方法是固定圓錐法（亦稱殘留圓錐法）。固定圓錐法將粉體注入到某一有限直徑的圓盤中心上，直到粉體堆積層斜邊的物料沿圓盤邊緣自動流出為止，停止注入，測定休止角。

theusual method of angle of repose is to fix the cone method (also called residualconic method).Fixed cone method : inject powder to  the center of disc with limited diameter,until the hypotenuse powder accumulation of material automatically  flow along the edge of disk, stop injection,measure angle of repose.

三.特點Characteristics：

測試粉末和顆粒通過漏斗的時間和形成的角度，測試前進行預(yù)堆積，從而已知樣品量，將已知質(zhì)量粉末從漏斗流出而形成的堆積角，以及流出所需要的時間；可以獲得休止角和流速數(shù)據(jù)。

testtime and angel of  powder and particle passthrough the funnel , preaccumulate before testing, so as to determine thesample weight, the known mass powder flowed from the funnel and form theaccumulation of Angle,  and  the time it takes to outflow;You can obtainthe  angle of repose and the flow ratedata.

用休止角評價粉體的流動性能，只能表示流動性的好壞，或者用于比較同種粉體因水分和粒度等引起的流動性差別。

Withthe Angle of repose evaluation flow properties of powders, can only say thestand or fall of liquidity, or used to compare the same powder liquiditydifference caused by moisture and particle size, etc.

參照GB11986-89《表面活性劑 粉體和顆粒休止角的測定》

Itwas designed and manufacured According to GB11986-89 "determination ofsurfactant powder and particle angle of repose "

Italso Applies to USP (the United States pharmacopoeia), BP (Britishpharmacopoeia) and EP (European pharmacopoeia) specification requirements ofthe reference standard: DIN, ISO 4324 - December 1983.

四.適用范圍scope of application：

用于制藥、工業(yè)化學(xué)、洗滌、科研院校、質(zhì)檢機構(gòu)等等相關(guān)粉末粉體及顆粒材料之檢測；可以提供粉體儲藏性質(zhì)的變化在料倉中儲存情況等。

Theyare widely used in pharmaceutical, chemical industry, washing, scientificresearch institutions, quality inspection institutions, and so on relateddetection of powder and granular materials;Changes in the properties of thepowders can be provided, especially in the silo Storage conditions etc.
