(december 20th) on december 15, 2017, zhejiang zhejiang manufacturing brand construction promotion association approved the release of the “zhejiang manufacturing” group standard “pre-coated coil coating for construction”, the standard number is t/zzb 0293-2017. it will be implemented as of december 22, 2017.
the standard was developed by the zhejiang provincial institute of standardization. zhejiang tiannian group paint co., ltd., a key domestic coil coating manufacturer, was drafted. the national coating quality supervision and inspection center, the national chemical building materials quality supervision and inspection center, and zhejiang province product quality and safety testing. research institutes and other national and provincial inspection and testing institutions, responsible for drafting units of peer companies and downstream major users to participate in the drafting.
the "zhejiang manufacturing" group standard "pre-coated coil coating for construction" is based on the chemical industry standard hg/t 3830-2006 "coil coating", with reference to the requirements of similar products of the international advanced enterprise akzo nobel, combined with the pre-construction the development trend of energy-saving, high-efficiency and high-performance technology of coated coil coatings was formulated in accordance with the requirements of the “zhejiang manufacturing” standard positioning. compared with industry standards, the standard increases the requirements of key technical indicators such as volume solid content, neutral salt spray resistance and artificial aging resistance, and increases the curing time, boiling water resistance, alkali resistance and other technical indicators, including curing time and resistance. the key technical indicators such as artificial aging are better than the international similar products. the main technical indicators have reached the level of “domestic first-class, international advanced” and made quality commitments to products and services.
"zhejiang manufacturing" group standard "pre-coated coil coating for construction" is based on the industry standard and international advanced standards. based on the consumer perspective, with the goal of improving user experience and satisfaction, the product life cycle concept and system analysis method are followed. the standard of the first-class products that meet the requirements of the "zhejiang manufacturing" standard and the domestic first-class enterprises to stabilize production in batches is formulated. the basic requirements of product design and development, raw material control, process technology, production equipment, environmental protection, etc., as well as technical requirements, application requirements and quality commitments, fully reflect the true material of the product (high volume solid content, large coating amount), energy saving (low baking curing temperature, short time), good processability (t-bend, strong cross-hatch adhesion), durable (acid, alkali, neutral salt spray, resistant features such as excellent aging performance.
