Tianjin Inspection and Quarantine Bureau paint inspection invention won national patent

China Coatings Online News Information: Recently, by the Tianjin Inspection and Quarantine Bureau Industrial Product Safety Technology Center invented a "simultaneous detection of benzene and ether substances in coatings" by the State Intellectual Property Office patent authorization.project aims to solve the current import and export of China's building coating testing methods. In recent years, with the sustainable development of the building materials industry, the number of imports and exports of building coatings in China continues to increase. From the point of view of protecting human health, China has promulgated a series of national standards, which clearly define the limits of the content of harmful substances in different kinds of paint products.in the traditional practice, the detection of benzene series of substances in coatings and the detection of ether substances need to use two instruments, using two methods to measure separately. Paint belongs to import and export commodities, but also belongs to China's inspection and quarantine departments focus on the supervision of commodities. Faced with a huge amount of detection, the traditional detection methods in the detection time, instrument use, labor costs have a greater consumption.It is understood that the new detection method can detect benzene and ether substances in the coating at the same time, using the gas chromatography test sample equipped with hydrogen flame ion detector, to obtain the detection map, through the map area calculation of the content of benzene and ether substances in the sample. Compared with the traditional method, this method has the advantages of saving human and material cost, high recovery rate and small deviation from the standard., the method has been applied in Tianjin port import and export paint testing, detection efficiency has been greatly improved.
