Recently, the scientific and technological plan projects of Fujian provincial market supervision and Administration Bureau, namely, the research on the initial water resistance of exterior wall stone paint, the research on the quality and safety evaluation system of new marine aquaculture plastic cage products, and the research on the detection technology of seven perfluorocarboxylic acids in food contact materials undertaken by FQII successfully passed the review and acceptance, and the project achievements reached the domestic leading level.

    The project "Research on the initial water resistance of exterior wall genuine stone paint" designed and established the test method for the initial water resistance of exterior wall genuine stone paint, and published 2 professional papers. The project "Research on the product quality and safety evaluation system of new-type plastic cage for marine aquaculture" has established the product quality and safety evaluation system of new-type plastic cage for marine aquaculture, and has published 3 professional papers. The project "Research on detection technology of seven perfluorocarboxylic acids in food contact materials" has established a pre column Derivatization Gas chromatographic analysis method for the content of seven perfluorocarboxylic acids in food contact materials, which is fast, accurate, economical and environmental friendly, and has published one professional paper.

    The research results of the above three projects have good social benefits and application value. They provide a convenient and effective test, evaluation and test method for assessing the initial water resistance of seven perfluorocarboxylic acids in food contact materials and exterior wall real stone paint, and have a strong guiding significance for the risk monitoring, quality improvement, relevant inspection methods and technical standards formulation of new marine aquaculture plastic net box products. The three project studies have filled the gaps in domestic research in these fields, provided reference and reference for relevant testing and research institutions to carry out relevant evaluation work, and provided formulation suggestions for manufacturers.
