粉体颗粒状态与流动性的关系

粉体颗粒状态与流动性的关系

摘要本文以粉体颗粒状态与流动性的关系为研究重点,采用粉体特性综合测试仪,分别测试了8个粉体样品的休止角、平板角、松装密度、振实密度、分散度等参数,得到样品的Carr流动性指数,评价了8个样品的流动性;通过激光粒度分析仪测了粉体的平均径、中位径、峰值径以及累积百分率处粒子的粒径以及粒径分布;用图形图像分析仪测试分析了样品的粒形。

对样品的流动性与粉体粒形、粒径及其颗粒分布的关系进行了分析。

分析结果表明,8个样品流动性好坏依次为:2号>1号>4号>5号>3号>6号>8号>7号。

粉体的流动性与颗粒的球形度成正比,球形度越大,流动性越好。

8个样品中2号球形度最大、流动性最好,7号球形度最小,流动性最差。

关键词:粉体流动性Carr指数粒形粒径abstractThis paper focuses on the research of the relationship between the powder particles state and liquidity, and respectively tests the angle of repose, flat angle, apparent density, tap density and dispersion and other parameters of eight samples. Carr index table is referred and Carr indexes are obtained. The liquidity performance of the eight samples in sequence is: No.2 > No.1 >No.4 > No.5 > No.3 >No.6 > No.8 > No. 7. The median diameter, the number average diameter and the cumulative percentage of the particle size and size distribution of particles of the powder are measured by laser particle size analyzer. Besides, the particle shape of the sample is tested by image analyzer and analyzed. The results show that the liquidity of powder is in direct proportion to the spherical degree of particle, namely, the greater the spherical degree is, and the better liquidity is. In the eight samples, spherical degree of No. 2 is the largest and its liquidity is the best; spherical degree of No. 7 is the smallest and its liquidity is the worst.Keywords: Powder; Liquidity; Carr Index; Particle Shape; Particle Size目录摘要 (I)abstract (II)0 引言 (1)0.1 研究背景 (1)0.2 粉体流动性的表征方法 (1)0.3 粉体流动性的影响因素 (2)1.实验样品与实验方法 (4)1.1实验样品 (4)1.2实验方案 (4)1.3 试验仪器 (4)1.3.1 BT-1000粉体特性综合测试仪 (4)1.3.1.1测试原理 (4)1.3.1.2测试方法 (5)2.实验结果与分析 (7)2.1粉体carr指数的测定及结果分析 (7)2.1.1流动指数分析 (7)2.1.2压缩度分析 (7)2.2激光粒度分析 (8)2.3粉体的粒形测试及流动性分析 (8)结论 (15)致谢 (16)参考文献 (17)0 引言0.1 研究背景所谓粉体,是由不连续的微粒构成,是一类特殊的固体,同时具有液态和固态的性质。

中图分类号 : TF1241 35 文献标识码 :D 上个月在美国佛罗里达召开了 “PIM2007” 会议 , 美国金属粉末工业联合会金属注射成形协会的主席 Mat2 t hew Bulger 先生在会上发表对北美粉末注射成形市场的评论时说 “虽然北美金属注射成形产业增长的速度慢 : 于亚洲和欧洲 ,不过现在金属注射成形协会会员企业对这一行业的信心在过去的几年里持续增加 ,2006 年北美 金属注射成形产业对新设备的定单增加了 ,金属注射成形产业从业人员的职业信心增强了” 。2006 年北美地区 金属注射成形零件产品的销售额为 11 75 亿美元 , 而 2003 年北美地区的销售额只有约 1 亿美元 , 虽然低于预期 的增长 , 但 Mat thew Bul ger 认为这个增长速度还是可以接受的。北美地区粉末注射成形制品的主要市场在医 疗器械制造领域 ,约占北美地区粉末注射成形制品市场总份额的 36 % 。五金制品 Matt hew Bul ger 先生认为 , 2008 年美国粉末注射成形制品在医疗器械制造领域的市场会进一步增长 ,仍会是北美粉末注射成形制品市场 最盈利 , 并占据市场统治地位的产品 ,他预计 2009 年北美的情况也基本是这样 。 Mat t hew B ulger 先生将导致北美粉末注射成形制品市场增长的因素归结为 : 新材料的开发 , 更严格的 公差控制 ,节约了能源和原材料 , 以及工程师的技术水平普遍得到了提高等 。根据一份对注射成形协会会员 企业的调查 : 现在人们对粉末注射成形技术和其应用的了解更多了。人们对粉末注射成形知识的增加也可 部分归结为粉末注射成形产业的高速增长 。M att hew B ulger 认为还有很长的路要走 ,需要开发新材料 , 进 一步降低生产费用。为了达到公差控制的标准仍有一些问题有待解决 , 为了制订有关标准人们已经忙碌了 多年 ,这项工作仍需要完善 。一份对金属注射成形企业会员的统计材料表明 :所有的回答者均对研究开发的 成果感兴趣 , 但很少有人会投资搞开发 。现在在粉末注射成形领域研究开发的方向主要是 : 钛金属 、 功能梯 度材料 、 低成本金属粉末 、 新型合金及提高粉末注射成形零件产品的质量等 。我们的责任是做一些行业基础 工作 ,这也是美国金属粉末工业联合会支持粉末冶金行业研究开发和市场开拓工作的一部分。 Yoshi yuki Kato 发表了一份关于亚太地区金属注射成形制品生产状况的论文 , Yoshiyuki Kat o 对亚太 地区国家金属注射成形市场分别进行了分析。200 6 年在日本有约 30 个生产金属注射成形制品的公司 , 金 属 注射成形制品的市场规模约为 1 1 3 亿美元 , 产品的主要应用领域集中于汽车制造 。 金属注射成形制品在 (下转第 4 5 页 )

粉体的基本性质及功能

粉体的基本性质及功能

粉体的基本性质及功能《营销界•化妆品观察》2011年1月27日作者:裴廷镐【小中大】彩妆按照分散技术不同,可分类为粉体(powder)彩妆、乳化彩妆、油分散彩妆。

粉体的作用是,为化妆品赋予色调,或构成产品的骨骼。

本文欲从粉体的基本特性着手,带大家了解使用在化妆品上的粉体的特性及功能、用于改善粉体的功能的表面处理方法。

1. 粉体的基本特性粉体(powder material)可以视为固体、液体、气体以外的第四性状。

粉体和固体一样拥有结晶性,与液体一样拥有流动性,与气体一样在不同的粒度(grain size/granularity)表现出飞散(free flowing)性。

粉体是多个固体微粒的集合体,粒子之间有一定的相互作用存在。

考虑一种粉体粒子的基本性质时,应区分粒子的大小、表面能量、表面构造、表面物性等因素。

如果按粒子大小分类可分为——广义的粉体:1 nm ~ 1 mm,狭义的粉体:< 50 um,微粉体:1 um ~ 50 um,超微粉体:10 nm ~ 1 um。

粉体以1um粒度为分界线,表现出的物理、化学性质有以下差异(见表1)。

λ粗大粒子(Macro particle)的特征——不凝集、流动性增加。

λ微粒子的特征——粒子的附着力增加,超过重力的影响而出现凝集。

粒子的大小小于1um时大于1um时增加的物理性质表面积,表面活性,反应性,凝集性,吸液量流动性,充填性,纯度增加表1.粒子大小与物理性质粉体粒子的物理性质可分为粒子性质与粉体性质(见表2)。

作为粒子的性质作为粉体的性质结晶质的大小、排向大小和分布外观密度形状充填构造构造流动性密度吸液量附着力表面的性质表2.粉体粒子的物理性质2. 化妆品用粉体的特性化妆品用的粉体可以分为无机颜料(体质颜料、白色颜料、彩色颜料)、有机颜料、天然颜料、珠光颜料等等(详见表3)。

体质颜料:是构成骨骼的原料,以天然的粘土矿物如云母、滑石粉最具有代表性,另外还有高岭土(kaolin)、碳酸钙、碳酸镁等等。
