    FT-104B系列休止角测定仪

    FT-104B Series angle of repose meter

    一.定义Definition:

    休止角是指粉体堆积层的自由斜面在静止的平衡状态下,与水平面所形成的角


    洗涤剂休止角测定仪 

    the angle of repose is the maximum angle formed between the free slope of the powder 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圆锥法(亦称残留圆锥法)。固定圆锥法将粉体注入到某一有限直径的圆盘中心上,直到粉体堆积层斜边的物料沿圆盘边缘自动流出为止,停止注入,测定休止角。

    the usual method of angle of repose is to fix the cone method (also called residual conic 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.

    特点Characteristics:

    测试粉末和颗粒通过漏斗的时间和形成的角度,测试前进行预堆积,从而已知样品量,将已知质量粉末从漏斗流出而形成的堆积角,以及流出所需要的时间;可以获得休止角和流速数据。

    test time and angel of  powder and particle pass through the funnel , preaccumulate before testing, so as to determine the sample weight, the known mass powder flowed from the funnel and form the accumulation of Angle,  and  the time it takes to outflow;You can obtain the  angle of repose and the flow rate data.

    用休止角评价粉体的流动性能,只能表示流动性的好坏,或者用于比较同种粉体因水分和粒度等引起的流动性差别。

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

    参照GB11986-89《表面活性剂 粉体和颗粒休止角的测定》

    It was designed and manufacured According to GB11986-89 "determination of surfactant powder and particle angle of repose "

    ISO4324-1977要求;粉体和颗粒休止角的测定,

    ISO4324-1977 requirement; The determination of the Angle of repose t for powder and particle

    It also Applies to USP (the United States pharmacopoeia), BP (British pharmacopoeia) and EP (European pharmacopoeia) specification requirements of the reference standard: DIN, ISO 4324 - December 1983.

    四.适用范围scope of application:

    用于制药、工业化学、洗涤、科研院校、质检机构等等相关粉末粉体及颗粒材料之检测;可以提供粉体储藏性质的变化在料仓中储存情况等。

    They are widely used in pharmaceutical, chemical industry, washing, scientific research institutions, quality inspection institutions, and so on related detection of powder and granular materials;Changes in the properties of the powders can be provided, especially in the silo Storage conditions etc.
