Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the national digital imaging materials and digital printing materials Standardization Technical Committee (SAC/TC432) centralized. This standard was drafted. Lucky Wah Kwong Printing Technology Co., Ltd. The main drafters of this standard. Huai Gong Li synthesis, peak, Fang Lei, Zhang Gang, Zhang Li, Lan Xiaoli, Huang Jianli. Digital printing material with an average molecular weight film-forming resin Its distribution was measured by gel permeation chromatography

1 Scope

This standard specifies the use of gel permeation chromatography using digital printing materials and film-forming resin molecular weight distribution methods. This standard applies to the phenol, cresol, phenol or one of the two or three mixed phenol and formaldehyde reaction of the film-forming resin. Applicable The average weight average molecular weight in the range of 2000 to 40,000, a molecular weight of 500 to 5000 data, the distribution coefficient of 4.0 to 8.0.

3 Terms and Definitions

Terms and definitions GB/T 21863-2008 defined in 3.1 are applicable to this document.

4 principle of the method

Gel permeation chromatography is the use of polymer molecules through the porous filler is filled with a special column, the column according to the molecular scale Inch size separation, molecular volume (molecular weight) to a large outflow small due to the long residence time in the column effluent and then, the effluent After detection, and automatic recording parameters such as molecular weight and molecular weight distribution of the sample to obtain a GPC chromatogram. The root of this spectrum According to the standard curve using standard polystyrene samples of known molecular weights obtained, calculated relative molecular weight and molecular weight distribution of the sample And other data.

5 Sampling

Sampling methods to perform according to the provisions GB/T 6679 and GB/T 3723's.

6 Reagents

Former tetrahydrofuran, HPLC grade, need to use degassed. Benzene, AR. Narrow distribution polystyrene standards, distribution coefficient D≤1.10. ......
