关于套胶硬度的说明

<div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">现在的乒乓套胶市场上，比较直观的有两大技术参数，也就是：厚度和硬度。</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">厚度的标准市场上比较统一都是国际度量标准mm。</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">而硬度的标准就分两类了：一个是729的邵氏W，还有就是DHS的邵氏A。</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><br/></div><div style="font-family: Verdana; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"><br/></div>

<div><span style="font-family: Verdana;">这两种硬度计的主要区别在于：</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">邵氏W：主要用于用于测定含有发泡剂制成的橡胶、塑料微孔材料硬度。</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">精确程度：±1度</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">测量厚度：10±0.5mm</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><br/></div>

<div><span style="font-family: Verdana;">由于此硬度压针直径为5mm，所以测试海绵这类相对于硬度不均匀的产品来说，受力面广</span></div><div><span style="font-family: Verdana;">，精确度较高，而其测试的数值也较“邵氏A”大。</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">邵氏A：适用于橡胶、塑料等科研单位、橡胶塑料制品的生产单位，能准确测出橡胶塑料</span></div><div><span style="font-family: Verdana;">标准试片的标准硬度</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">精确程度：±1度</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">测量厚度：6±0.5mm</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><br/></div>

<div><span style="font-family: Verdana;">此硬度计锥端直径只有0.8mm，其受力面小，要精确测试就要多次，在一块产品上选多个</span></div><div><span style="font-family: Verdana;">点，进行测试，得出平均值.</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">729与DHS基本换算明晰如下：</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">729 硬度范围为：反胶 40~48度 正胶35~40度</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">分为中软 中硬两种</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><br/></div>

<div><span style="font-family: Verdana;">反胶：</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">中软相当与40~44度之间</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">中硬相当于44~48度之间</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">DHS硬度范围为：反胶38~41度4个等级</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><br/></div>

<div><span style="font-family: Verdana;">对比如下：</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">729中软 邵氏W 43~44度 相当于 DHS 邵氏A 38度</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">729中硬 邵氏W 45~46度 相当于 DHS 邵氏A 39度</span></div><div><span style="font-family: Verdana;"><br/></span></div><div><span style="font-family: Verdana;">729中硬 邵氏W 46~47度 相当于 DHS 邵氏A 40度</span></div><div style="font-family: Verdana; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"><br/></div>
