专业陶瓷贴花开发人员Xerital提出了一个串行条形码系统,可以应用于玻璃基板 - 现在,世界领先的吸附剂样品管制造商Marks Markes International已完全切换到此方法上的玻璃管标记方法。
Xerital的高温贴花实际上是在玻璃管上发射的,从而产生了永久性标记,该标记对刮擦,化学攻击和热过程具有很强的抵抗力。最终发射的产品不仅非常耐用,而且提供了高分辨率输出,这对于准确的代码扫描和阅读至关重要。
Already being successfully applied in the production of ceramic sanitaryware, where the firing temperature is more than 1200°C, the barcodes yield valuable information on product tracking and operative performance, through to warehousing, stock control and, finally, to the ‘in-service’ stage.
十多年来,Markes International(总部位于南威尔士镇兰特里斯特(Llantrisant)距加的夫(Cardiff)约20公里)开创了分析热解吸(TD)仪器和相关的采样设备。2020欧洲杯下注官网标记也具有市场上最广泛的热解消耗品。
作为热解技术的世界领导者,Marks International的精神牢固地专注于创新和设计有助于使客户生活更轻松的产品。
这项承诺导致其决定增强吸附管的标签。这些用于从空气中捕获挥发性有机化合物(VOC),并随后进行实验室分析。在现有的吸附管系列上的标签包括一个字母数字序列号和标记品牌,但现在需要以条形码格式包含序列号。
在吸附管上有条形码是一个必不可少的要求,因为它可以帮助客户在录制和跟踪样品时减少错误,并消除耗时的手动数据输入。条形码还必须采用代码128格式,以提供最佳的长期可读性。这种特殊的格式是一种超高密度线性符号学,旨在编码文本,数字和众多功能,因此之所以如此,是因为它具有整个128 ASCII字符集。
Switching to Decals
对于Markes的不锈钢采样管系列,该公司始终使用激光标记过程取得了良好的效果。但是,发现这不适合在玻璃管范围内创建条形码,因为它无法制作所需的详细且明确定义的标记。因此,标记团队着手确定替代过程。
“The requirements of this job were very challenging”, explains Steve Oldfield, Consumables Product Manager at Markes International, “and any solution had to be precisely tailored to our requirements in order to meet our high standards.
“Once VOCs have been sampled on to our sorbent tubes, they are analysed by thermal desorption–gas chromatography. As part of this process, the tube has to be heated to a high temperature under a flow of inert gas and for some applications the temperatures can be as high as 400°C.”
The tubes also have a long lifetime (the sorbent inside the tubes can itself last for up to 200 thermal cycles), so the barcode had to be hard-wearing. In addition to this, the barcode had to be formed on the tube’s relatively small curved surface but still be easily readable by a hand-held scanner.
标记了几个制造商的样品,他们均应用了专门为高温应用设计的条形码“标签”。不幸的是,这些测试发现,在延长的高温下,标签被弄脏和不可读。
此后,史蒂夫(Steve)和他的同事探索了高温油漆的使用,但是墨水施用过程被证明是有问题的,并且与其他方法一样,在暴露于长时间的高温下,它的表现并不特别好。
发现Xerital
“When we met with the team at Xerital, we straight away found them to be very positive and quick to gain a clear understanding of our requirements” says Steve. “The samples they provided for us were applied using a kiln-fired ceramic decal and our testing showed these to be extremely good. In particular, the white ceramic background made barcode-reading far more reliable than with sorbent tubes from other suppliers, where the barcode had been applied directly on the glass.”
条形码贴花也被证明是耐用的,并提供了持久的质量。作为射击过程的一部分,它们的加热至700°C,因此它们在实验室分析期间的高温下表现良好。
Xerital总监Howard Quinn评论说:“ Markes International的该项目已成为我们专业陶瓷贴花在玻璃应用方面的优势的极好证明。”“我们非常紧密地合作以取得成功,我认为从技术上讲,随着过程的形成,我们和标记都向前迈进。很高兴与史蒂夫及其团队合作。”
The Xerital barcode decals can be applied to new or existing tubes and are particularly useful for large-scale monitoring studies and for labs with significant sorbent tube stock. High-temperature barcodes can be serialised to customers’ required size and code and integrated into their existing IT system.
史蒂夫·奥尔德菲尔德(Steve Oldfield)总结说:“现在,我们的全部玻璃管量都由Xerital进行了条形码,其持续的过程改进确保了产品质量仍然是最高级别的。”“我们致力于建立与Xerital的关系,现在正在探索创新的方式,将颜色标签引入我们的玻璃管系列。”
