Nanjing Engineering produces meltblown cloth for Yihua to strictly control the cleanliness of air ducts

The meltblown cloth production line has very high requirements on the internal cleanliness of the air duct.
In accordance with the quality requirements of "creating high-quality projects" and adhering to the concept of "quality is the life of an enterprise", the Nanjing Engineering Yizheng Project Department has adopted a series of quality control measures: First, the air duct After the arrival of the product, the finished product should be protected, and the nozzle should be closed in time to prevent debris from entering; the second is to store the air duct to be cleaned in a closed workshop to ensure the surrounding environment is clean, and at the same time, use a rubber pad under the air duct to isolate; Before installing the air duct, arrange a special person to clean it up, wearing dustproof clothing, dust caps, and shoe covers; fourth, use a vacuum cleaner to clean the dust inside the air duct, and then wipe it with a clean cotton cloth, and check the layers.
Ensure the internal cleanliness; Fifth, the process air duct is washed with water, and the on-site welding port is wiped with a pickling cloth, and the dough is cleaned; Sixth, the protruding inner wall of the gasket between the flanges is cut flat with a knife to prevent dust retention; Seventh, strict implementation of " "Quality three inspection system", after passing the self-inspection, jointly inspect with the quality supervision station and the owner, and then carry out the follow-up process after reaching the standard; eight is to purge the air supply system in time until the cleanliness of the air outlet meets the requirements
