margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; 乌斯特公司1999年6月在巴黎ITMA展览会上首次展出了其首台采用全自动纤维采样系统的HVISpectrum型棉花综合测试仪,如图4-1所示。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; max-width: 100%; overflow-wrap: break-word !important; outline: none 0px !important; height: auto !important;"></p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; font-size: 14px; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 该仪器首次采用了全自动纤维取样系统,降低了试验人员劳动强度,测试人员由两人减为一人。HVISpectrum系统能够测量棉纤维的长度、长度整齐度、强度、伸长率、马克隆值、色泽等级和杂质等指标;它还可以提供成熟度、棉花回潮率、短纤维率指标。成熟度指标由强度、马克隆、伸长率3个指标通过经验回归方程计算得出,其结果与AFIS的成熟率及显微镜法得出的结果非常吻合,相关系数达到0.93。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 并可把NEPTESTER720棉结测试仪和UV仪集成在一起;还能按国际贸易标准,在很短的时间内完成对棉包棉样的分析,并加以评等评级。完全自动化的设计使得棉花采购和日常的配棉管理非常简单易行。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; HVISpectrum型棉花综合测试仪与以往设备不同,棉花测色部分由白炽灯光源更改为氙灯光源。主要原因是氙灯属于闪烁发光,而不是常亮,故其发热量较小,对仪器稳定性的影响减小了;氙灯发光强度的稳定性较白炽灯好,且不需经过长时间预热即可达到测试所需强度,有利于提高测试效率。另外,HVISpectrum仪器配套的校准色板与HVI900型仪器的校准色板不同,乌斯特公司官方解释是由于氙灯和白炽灯的发光光谱并不完全一样。标准色板色度空间的变化对棉花色度的测试结果没有显著影响,乌斯特公司已经做了两者的比对测试,两型号仪器对同一样品12次测试结果的均值是吻合的。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; HVISpectrum型棉花综合测试仪装配了新型电阻回潮传感器,传感器通过对样品施加固定压力,确保回潮测试结果的稳定可靠。仪器采用测得的棉花回潮结果对棉花强度测试结果进行修正,从而降低了对实验室环境温湿度的要求。短纤维含量指标通过对照影图按照经验统计公式计算得出,该经验公式是乌斯特公司通过3年的统计分析得出的,其测试结果与AFIS重量加权短纤维含量测试结果非常一致。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 为满足棉花分级机构、大批发商、大型纺织厂短时间内测试大量样品包的要求,乌斯特公司于2002年6月正式向市场推出了HVI900Classing型棉花综合测试仪,如图4-2所示。</span></p><p style="max-inline-size: 100%;
