Wenzhou Institute of Metrology successfully developed cement fineness negative pressure sieve analyzer detection device

【Chinese instrument network instrument research and development】 To meet the requirements of building metrology and measurement, the metrology institute of Wenzhou City, Zhejiang Province has established a technical team of senior engineers as the backbone. Through six months of research on more than a hundred construction units, it has conducted in-depth analysis of structural principles. According to GB/T1345-2005 "cement fineness test method screening analysis" and JJF1175-2007 "test sieve calibration specification" of the relevant provisions, in recent days successfully developed a cement fine negative pressure sieve analyzer detection device.

The successful development of the detection device is widely used in construction engineering units. The construction party can correct the parameters of the negative pressure which is easily over-excessive, so as to accurately control the cement fineness index and ensure the construction quality of the project.

The successful development of this detection device fills the gap in the field of negative pressure value checking equipment for negative pressure screening analyzers in China, enabling third-party testing organizations to effectively implement traceability of values, and calibrates cement fineness negative pressure screening analyzers. It also lays a solid foundation for the future development of national cement verification protocols or calibration specifications for the “Cement Fineness Negative Pressure Screen Analyzer”.

Cement fineness indicates the degree to which the cement is ground or the degree of dispersion of the cement. The cement fineness negative pressure sieve analyzer is a special instrument for measuring the fineness of cement such as Portland cement, and is a cement plant, a construction company, and a building and highway. Testing laboratory necessary measurement equipment.
