巴氏硬度计使用说明书

巴氏硬度计简介：巴氏硬度计（巴克尔硬度计）是一种压痕硬度计，它以特定压头在标准弹簧力的作用下压入试样，以压痕的深度确定试样的硬度。

巴氏硬度计有100个刻度，每个刻度代表压入0.0076mm的深度。

可测量的材料：铝、铝合金、软金属、塑料、光纤、消防梯、复合材料、橡胶或皮革。

玻璃钢等。

用途巴氏硬度计主要用于测试铝及铝合金。

测试铝型材、板材、管材、棒材及铝合金铸件、锻件、机械加工零件，测试超厚铝合金材料及组装后的铝合金制品（例如铝合金门窗、幕墙、消防梯等）。

相关标准：ASTM B648《巴柯尔硬度计测量铝合金硬度的试验方法》。

巴氏硬度计的另一主要应用是用于测试玻璃钢（玻璃纤维增强塑料）和硬塑料。

大部分玻璃钢制品的产品标准中都要求测试巴氏硬度。

相关标准：GB/T3854—2005《增强塑料巴柯尔硬度试验方法》、ASTM D2583—07《巴氏硬度计测量硬塑料压痕硬度的试验方法》。

巴氏硬度计的改进型935—1、936—1可用于测试很软的金属、软塑料、皮革、橡胶、木材等。

工作原理巴氏硬度计（巴柯尔硬度计）是一种压痕式硬度计，它以特定压头在标准弹簧的压力作用下压入试样表面，以压痕的深浅表征试样硬度的高低。

巴氏硬度计有100个分度，每个分度单位代表压入0.0076mm的深度。

压入越深，读数越高，材料越软。

巴氏硬度公式为：HBa=100-L/0.0076式中:HBa—巴氏硬度符号； L —压痕深度（mm）； 0.0076—单位硬度值代表的压痕深度（mm）目录一、概述 (1)二、原理与结构 (2)三、技术参数 (3)四、使用方法 (3)五、仪器校正 (4)六、压针 (5)七、硬度块 (7)八、测量次数 (7)九、型号选择 (8)十、配置 (8)十一、硬度换算表 (9)一、概述巴氏硬度计(巴柯尔硬度计)是一种压痕式硬度计，最早产自美国。

巴氏硬度计有三种型号，其中OU2800-1型巴氏硬度计是代表型产品，应用量最大，一般提到巴氏硬度计主要是指OU2800-1型。

氯氰菊酯含量的分析方法

GB 9565—881 主题内容和适用范围本标准规定了氯氰菊酯含量的分析方法。

本标准适用于氯氰菊酯原药、乳油的有效成分含量的测定。

有效成分：氯氰菊酯化学名称：（±）α-氰基-3苯氧基苄基（±）顺式、反式-3-（2，2-二氯乙烯基）-2，2-二甲基环丙烷羧酸酯结构式：分子式：C22H19Cl2NO3分子量：416.31（1983年国际原子量）2 分析方法气相色谱法2.1 方法提要以癸二酸二壬酯为内标，在5％OV-101/Gas Chrom Q（60～80目）柱上，进行气相色谱分析。

2.2 试剂氯氰菊酯标准品：已知准确含量；内标物：癸二酸二壬酯，（没有与氯氰菊酯分不开的杂质峰）；色谱固定液：硅酮OV-101；担体：Gas Chrom Q（60～80目）；甲苯（GB 684）：分析纯；内标溶液：准确称取癸二酸二壬酯0.72g（精确至0.0002g），于10mL容量瓶中，用甲苯稀释至刻度，摇匀。

2.3 仪器气相色谱仪、氢火焰离子化检测器；色谱柱：1m×0.3（内径）cm不锈钢柱，内填5％OV-101/Gas Chrom Q（60～80目）；记录仪：5mV（或数字积分仪）；微量注射器：10µL。

2.4 操作步骤2.4.1 色谱柱的制备2.4.1.1 固定液的涂渍：准确称取0.5g左右OV-101置于100mL小烧杯中，加三氯甲烷使溶解（三氯甲烷量以能浸没担体），称取确定量的担体（约10g），在轻轻摇动下，加至固定液溶液中，不时摇动，使涂布均匀（最好在通风橱中进行），自然挥发干后，于110℃左右烘箱中干燥2～3h，即可装柱。

2.4.1.2 色谱柱的填充：将洗净、烘干的不锈钢柱，一端接小漏斗，另一端塞适量玻璃棉，裹以纱布后，通过橡皮管与真空泵相连。

开启真空泵，从漏斗处分次加入已制备好的填充物，同时不断轻敲管壁，使填充物均匀、紧密地填满色谱柱。

在入口端塞一小团玻璃棉，并适当压紧，以保持填充物不被移动。

具有渐开线齿廓的花键轴连接DIN5480内容

DIN 5480 第二部分至 DIN 5480 的第十六部分适用于 30°压力角的花键轴连接。其中包含有结构尺寸、公差配合制度和量规的公差以及对标准滚切和插削工具的说明。
因为 37.5°和 45°压力角的花键轴连接的经济性被优选用于汽车工业的无切削滚压工艺中。对于这些连接使用美国标准。随着未来采用公制的发展要求，制定这一适当的标准作为 DIN 5480 的另一部份，届时 ISO 4156 - 1981 的标准偏差和公差将根据 DIN 5248 为依据来制定。
以下原理适用于此标准：
a) 所有齿距的基准齿形相同，因此所有齿廓都具有统一的构成原理。
b) 齿侧定心。仅在 30°压力角中例外地使用直径定心。
c) 在 30°压力角的花键连接中齿顶高变位的使用，是为了使其更好地达到标称尺寸。
d) 由下（花键套齿槽宽）偏差和上（花键轴齿厚）偏差以及为其确定的可自由选择的公差带组成配合系统。这主要是考虑到花键轴连接中固有的在所达到的齿廓间隙上有啮合误差的影响。
