  • Detail

The establishment and implementation of the alliance standard for the exhaust emission limit of the finalizing machine in the printing and dyeing industry was approved.

the project of establishing and implementing the alliance standard for the exhaust emission limit of the finalizing machine in the printing and dyeing industry, jointly applied by the printing and dyeing industry association of Keqiao District, Shaoxing City, Zhejiang Province and the Quality Inspection Institute of Keqiao District, was approved at the provincial level. The alliance standard for the formulation and implementation of exhaust emission limits for finalizing machines in the printing and dyeing industry was jointly declared by the printing and dyeing industry association of Keqiao District, Shaoxing City, Zhejiang Province and the Quality Inspection Institute of Keqiao district. This project has been approved for provincial approval and is one of the three industrial standardization projects in Zhejiang Province in 2014

in recent years, with the development of printing and dyeing enterprises, more than 40% of new residential buildings have used plastic doors and windows; More than 80% of the newly-built houses in Qingdao and Dalian have used the rapid expansion of the production capacity of the plastic window industry. The environmental complaints and pollution disputes caused by the waste gas emission from the finalizing machine are increasing day by day. The waste gas from the sizing machine is mainly composed of oil smoke, particulate matter and other pollutants. When the sizing machine works, the exhaust gas emission concentration is as high as 250 mg/m3 of particulate matter and 1000 mg/m3 of oil smoke, which has become one of the important environmental pollution sources in Keqiao district

for this reason, Keqiao District Bureau of quality supervision led Keqiao District printing and dyeing industry association and Keqiao District Institute of quality and technology supervision and testing to conduct in-depth investigation and Research on the project in accordance with the measures for the management of key projects of standardization of block industries in Zhejiang Province (for Trial Implementation) and other relevant regulations. By organizing the formulation and implementation of the alliance standard for the exhaust emission limit of the sizing machine in the printing and dyeing industry, the production behavior of enterprises was effectively standardized, the exhaust emission of the sizing machine was reduced, and the overall environmental protection level of the industry was improved

it is reported that the project plans to connect the strain gauge into the measuring circuit and plan to implement it in half of the enterprises of the association. After the completion of the project, the exhaust gas emission concentration will drop to 18 mg/m3 of particulate matter and 25 mg/m3 of oil smoke. It can reduce the total amount of particulate matter emitted by the shaping machine by about 2750 tons and the total amount of lampblack by about 11000 tons every year. To meet the national and provincial requirements for the waste gas emission of the printing and dyeing industry in the long-term use process
