Foreword

This standard is equivalent to using ASTMD3451.2006 "powder paint and coating testing standards Guide" (in English). Appendix A of this standard is an informative annex. This standard is managed by the National Standardization Technical Committee chemicals dangerous (SAC/TC251) and focal points. This standard is drafted by. Marine Chemicals Research Institute. Participated in the drafting of this standard. Jiangsu Entry-Exit Inspection and Quarantine Bureau, the Chemical Institute of Standardization, China National Chemical Construction Corporation, Changzhou Paint Chemical Research Institute. The main drafters of this standard. Tang Lijun, Miao Ye Qian, Jian Mei, Qian Jin, Yang East, Li Zhengwei, Shen Su River. This standard is the first release.

Introduction

The standard method of detecting the powder paint and coatings detailed provisions (see Appendix A), choose to use. In addition to special Specific requirements outside, this standard applies to thermoplastic and thermosetting powder coating. Functional powder coatings applied to steel pipes and reinforcement, but the present standard Registration is not intended to recommend testing methods and steps to cater to this rapidly growing market and developed. Suitable for reinforcement steel pipes and functionality Powder paint and coating testing, reference ASTMA01.05 and ASTMD01.48. In the practical application of this standard, selection and analysis methods to be based on the different needs and experiences of each one to determine, at the same time But also in the supply and demand sides to reach a consensus. It is noteworthy that, using a number of methods to highlight some of the characteristics of the powder coating, for example. condensate Gel time and inclination liquidity is only a comparison between the two coating materials, but can not determine the merits of this. Analysis of experimental results of system-dependent details Analysis and chemical properties of powder coatings. Powder paint and coating testing standards guide

1 Scope

This standard specifies the method for the detection of powder coatings and coating selection and use of the program. This standard specifies the specific detection method of powder coatings, such as. electrostatic spraying, fluidized bed as well as some other methods.
