概述與特性

Avian Technologies? 是唯一的丙烯酸熒光標(biāo)準(zhǔn)供應(yīng)商，廣泛用于辦公用紙及其它應(yīng)用的白色塑料標(biāo)準(zhǔn)。提供不同 CIE 白度的標(biāo)準(zhǔn)件，可選擇高光澤或啞光表面處理。

FTS 熒光標(biāo)準(zhǔn)板的熒光特性使其非常適合用于測(cè)量辦公紙張中常見的熒光增白劑（FWA）。在測(cè)量中，盡可能使用類似的標(biāo)準(zhǔn)始終是良好的做法。FTS 熒光標(biāo)準(zhǔn)板種類繁多，這意味著我們可以提供一個(gè)與待測(cè)紙張熒光特性非常接近的標(biāo)準(zhǔn)。我們提供測(cè)量服務(wù)，以幫助您確定最適合您產(chǎn)品的 FTS 熒光白度標(biāo)準(zhǔn)。

您可選擇成套或單獨(dú)的標(biāo)準(zhǔn)板，也可以定制您的成套標(biāo)準(zhǔn)板，聯(lián)系我們，確定您的最佳方案。

Comparison of Office Paper and AT-FTS-15a — Standard office paper and AT-FTS-15a (click for full size). Measured under illumination approximating the UV content of D65. The plot shows very similar properties, especially in the critical absorption region (350-400nm) and emission region (400-475nm). The 15a is an ideal reference standard to use for qualifying paper with OBAs.

Important Notes on Whiteness Measurements

We calculate CIE whiteness and tint as described in “Whiteness Assessment: A Primer Concepts, Determination and Control of Perceived Whiteness.” This document, which also serves as a comprehensive primer on whiteness, was provided by Dr. Claudio Puebla of Axiphos GmbH, and is?available for download?from the Axiphos GmbH site.

As of May 2014, we aligned our GretagMacbeth Coloreye 7000A to a traceable whiteness standard measured at NRC Canada. The UV content of out instrument was slightly low, and was increased to match the traceable standard. Therefore as a result of this recalibration our measured whiteness values are higher than previously reported. Our FTS formulations have not changed; if you want to purchase new standards that match your existing FTS standards, use the same part numbers.
