Nanjing Changrong Scholars Co., Ltd. (formerly Nanjing Changrong Noise Control Environmental Protection Engineering Co., Ltd.) was established in 2001. It is located in Nanjing City, Jiangsu Province, adjacent to Nanjing University, covering an area of ??more than 6,000 square meters.Factory, an annual output value of 50 million yuan, is a high -tech enterprise specializing in acoustic energy conservation and environmental protection industry.
The company mainly develops, produces, and sells various types of sound, sound, sound absorption, sound -absorbing, sound insulation, and vibrations.The company has passed ISO9001: 2008 Quality Management System Certification. It has the qualifications for environmental protection engineering professional contracting, environmental pollution governance Grade A qualifications, military confidentiality qualifications and weapons and equipment scientific research and means of research.The planned implementation unit, the Jiangsu Provincial Enterprise Intellectual Property Management Standardization Demonstration Create Advanced Units, Nanjing Intellectual Property Work Demonstration Enterprises, and Nanjing Heavy Contracts and Credit Enterprises.
In recent years, the company has obtained a number of national standards for scientific and technological plans at or above the provincial level of scientific and technological support plans such as the Ministry of Science and Technology Small and Medium Enterprise Technology Innovation Fund, and the Jiangsu Provincial Science and Technology Support Program, and hosted or participated in the formulation of national standards in the field of acoustics and vibration 3department.
Adhering to the development strategy of "the leading reputation of science and technology", the company has set up a team of vibration and noise control product research and development centers, and has a team of talents with a researcher -level senior engineer in the field of acoustic vibration.Piece software copyright.Relying on patent technology, the five major series of 20 major acoustic products have excellent performance, all of which have passed the testing of authoritative departments such as acoustic measurement test stations of the Chinese Academy of Sciences, National Architectural Materials Testing Center, and Beijing Labor Insurance Institute.In addition, some fist products have been rated as national key new products, provincial and municipal high -tech products, provincial and municipal patent new products, and have won many times of provincial and municipal science and technology progress awards, provincial environmental protection science and technology awards, provincial machinery industry science and technology progress awards, and provincial provincialCity Patent Award.It should be pointed out that products such as ultra -hole sound absorption materials, sound barriers and other products have passed the scientific and technological achievement appraisal of Jiangsu Province, and relying on the secondary development of aerospace technology to adjust the frequency -adjustable high sound wave blower.And reach the international leading level.
The company actively promotes the marketing and application of high -tech products, and customers and partners have spread all over the country.Among them, the high voice and control system has successfully applied the acoustic performance test of various types of aircraft, satellite, carrier rockets, large aircraft and other aircraft; various specifications of sound -absorbing materials, vibration reduction systems, and mufflers have been in aerospaceAviation, construction venues, road bridges, rail transit, industrial and mining enterprises, ship submarines, weapons and equipment and other areas are widely used; the adjustable frequency rigid high sound wave blower has successfully applied to 300MW, 600MW, 1000MW and other specifications of power plant boilers.In addition to the transformation of energy -saving technology transformation projects, the worldwide problem of GGH blocked in wet desulfurization has been completely solved, and the benefits of energy conservation and emission reduction have been achieved.
