On February 28, the polypropylene meltblown special material production line of Lanzhou Center of Petrochemical Research Institute was successfully started for one time, and qualified products were produced, marking the successful development of PetroChina's independent polypropylene meltblown special material. As of 9:00 on March 2, a total of 4.85 tons of polypropylene meltblown special materials were produced.
Since the outbreak of the new Novel coronavirus pneumonia epidemic, domestic demand for emergency supplies such as masks and protective clothing has exploded. In particular, the supply gap of meltblown non-woven fabrics for the production of masks and protective clothing and the production of raw materials has been huge. PetroChina immediately deployed scientific research on mask raw materials such as meltblown cloth and meltblown materials, with a view to solving the urgent needs of meltblown special materials.
The Petrochemical Institute quickly responded to the requirements of the party group deployment and refining and chemical branch of the group company, set up a joint working group, concentrated manpower and material resources, set up four working groups, clarified the division of responsibilities, time nodes and schedules, organized research on meltblown materials, meltblown cloth Production work.
The four tasks of cooperative production of meltblown cloth, meltblown material and meltblown cloth production test, and construction of new meltblown cloth project go hand in hand. The joint working group completed the implementation plan development, key equipment and equipment procurement, technical indicators and Contract signing, product standards and third-party testing, review of legal provisions, and agreement on cooperation details.
The Lanzhou Center of the Petrochemical Institute completed the negotiation of key equipment procurement and the installation of the twin-screw extruder in 8 days, overcoming the technical problems of melt index fluctuation and uncontrollable residual peroxide during the degradation of polypropylene, and achieved odor control and product homogeneity. Stable, using Lanzhou Petrochemical polypropylene fiber material S900 as raw material, producing meltblown material with melt index of about 1500 through degradation process, with test conditions for daily production of 2 tons of meltblown material, laying a solid foundation for self-produced meltblown cloth.
The Petrochemical Institute completed the research and development and production of meltblown materials in the shortest time, fastest speed, and ultra-conventional methods, and went all out to provide guarantee for the supply of basic materials and protective supplies for medical protective materials. In the next step, Petrochemical Institute will continue to accelerate the production of independent meltblown materials and technology promotion, establish a non-woven fiber innovation platform from scientific research and development, trial production, testing to standardization, and create a high-level research and development and production base for new materials. The victory of epidemic prevention and control and high-quality development contributed to the refining and technological innovation power.
