[China Instrument Network Instrument Development] Recently, a "method for simultaneous detection of benzene and ether materials in paints" invented by the Industrial Product Safety Technology Center of the Tianjin Inspection and Quarantine Bureau was patented by the State Intellectual Property Office.
The project aims to solve the current deficiencies in China's import and export of architectural paint testing methods. In recent years, with the continuous development of the building materials industry, the number of imported and exported architectural coatings in China continues to increase. From the perspective of protecting human health, China has promulgated a series of national standards that clearly stipulate the limit values ​​of harmful substances in different kinds of paint products.
In the traditional practice, the detection of benzene series substances in paints and the detection of ether substances require the use of two instruments, which are measured separately by two methods. Coatings belong to import and export commodities, but also belong to China's inspection and quarantine departments to focus on the supervision of goods. Faced with a huge amount of detection, the traditional detection methods consume a great deal of time in the detection time, instrument use, and labor costs.
It is understood that the new detection method can simultaneously detect benzenes and ethers in paints, use gas detectors equipped with a hydrogen flame detector to detect samples, and obtain detection patterns. The benzenes and ethers in the samples can be calculated from the map area. The content of material. Compared with traditional methods, this method has the advantages of saving manpower and material costs, high recovery, and relatively small relative standard deviation.
At present, this method has been applied to the full inspection of Tianjin port import and export paints, and the detection efficiency has been greatly improved.
