haohan色漆和清漆 涂料中水分含量的测定HH-PLOT Q毛细管柱30m*0.53mm*10um

本标准等同采用ISO国际标准：ISO 23168:2019。

采标中文名称:色漆和清漆 涂料中水分含量的测定 气相色谱法。
 

在许多工业用途中需要测定各种材料和产品中的水分含量。

这些用途可能包括工艺过程的质量控制、原材料或*终产品中水分含量的测定。

水作为水性涂料的一个重要组成成分，其含量对水性涂料的性能有显著的影响。

精准测定水性涂料中水分含量，对于优化水性涂料产品配方，优化生产工工艺及计算水性涂料中挥发性有机化合物（VOC）含量有重要的意义。

迄今为止，有两种常用方法被用来测定涂料中的水分含量。

 

近年来，随着毛细管色谱柱制备技术不断进步，某些型号毛细管色谱柱耐水性技术已经比较成熟。

毛细管色谱柱在柱长、分离度等方面均有优势，能有效降低干扰，结合自动进样器等技术，气相色谱法测定涂料中水分含量效率较高、精密度和正确度较好。

ISO 23168: 2019 《色漆和清漆—水分含量的测定—气相色谱法》于2019年4月发布，该国际标准由中海油常州涂料化工研究院主导制定，为我国涂料领域自主制定的首个ISO国际标准。

该标准以GB/T 18582-2008等我国的一系列强制性国家标准中有关水含量测定的内容为蓝本，结合国外的一些测试方法和检测技术的*新发展水平而提出，达到国际先进水平。

This standard is equivalent to the ISO international standard: ISO 23168:2019.

Mining standard Chinese name: paints and varnishes - Determination of moisture content in coatings - Gas chromatography.


Determination of moisture content in various materials and products is required in many industrial applications.

These uses may include quality control of processes, determination of moisture content in raw materials or final products.

As an important component of water-based coatings, water content has a significant impact on the performance of water-based coatings.

Accurate determination of the moisture content in water-based coatings is of great significance for optimizing the formulation of water-based coatings, optimizing the production process and calculating the volatile organic compound (VOC) content in water-based coatings.

To date, two common methods have been used to determine the moisture content in coatings.



In recent years, with the continuous progress of capillary column preparation technology, the water resistance technology of some types of capillary columns has been relatively mature.

Capillary chromatographic columns have advantages in column length, resolution, etc., and can effectively reduce interference. Combined with technologies such as automatic samplers, gas chromatography has high efficiency, precision and accuracy for the determination of moisture content in coatings.

ISO 23168: 2019 "Paints and Varnishes - Determination of Moisture Content - Gas Chromatography" was released in April 2019. This international standard was formulated under the leadership of CNOOC Changzhou Institute of Coatings and Chemicals. standard.

The standard is based on the content of water content determination in a series of mandatory national standards in my country such as GB/T 18582-2008, and is proposed in combination with the latest development level of some foreign testing methods and testing technologies, reaching the international advanced level.
