YS/T 728-2016Acrilic electrodeposition paint for aluminium alloy extruded profiles for architecture (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces YS/T 728-2010 "aluminum building profiles with acrylic electrophoresis coating." This standard and YS/T 728-2010 Compared to the main technical changes are as follows.

--- Modify the composition and viscosity of some electrophoretic coatings;

--- Increased electrophoretic coating performance level;

--- Increased electrophoretic coating of harmful solvents in the limited;

--- Increasing the composite membrane UV salt spray joint test requirements;

--- Alkali modified performance requirements;

--- Added "electrophoretic coating type and characteristics of" an informative annex;

--- Added "UV salt fog joint test method" informative appendix;

--- Added "Alkali Corrosion Potential Detection" normative appendix.

This standard is proposed and managed by the National Nonferrous Metal Standardization Technical Committee (SAC/TC243).

The main drafting units of this standard. Tianjin Development Zone Ai Long Chemical Technology Co., Ltd., Jiangyin Hengxing Coating Co., Ltd., the national non-ferrous metals Quality Supervision and Inspection Center.

Participated in the drafting of this standard. Guangdong Jian Mei Aluminum Factory (Group) Co., Ltd., Zhaoqing Asia Aluminum Works Co., Ltd., Suzhou Robertskin Aluminum Co., Ltd., Guangdong Xingfa Aluminum (Jiangxi) Co., Ltd., Fujian Minfa Aluminum Co., Ltd., Fujian Nanping Aluminum Limited, Guangzhou Nonferrous Metal Research Institute, Zhaoqing City, MMS Decoration Materials Co., Ltd..

1 Scope

This standard specifies the requirements of the acrylic anode electrophoretic coating aluminum profiles, test methods, inspection rules, signs, packaging, transportation Lose, storage and quality certificate and contract (or purchase order) content.

This standard applies to the aluminum electrophoretic coating industry, without dilution of the original anode electrophoretic coating (hereinafter referred to as the stock solution).
