GZ Petrochemical's newly developed melt-blown non-woven special material S-1500 has been successfully trial-produced, and the first batch of products have been trialed by downstream melt-blown non-woven fabric processing enterprises.
Since the outbreak of the new Novel coronavirus epidemic, Guangzhou Petrochemical has actively fulfilled its social responsibilities, urgently changed its production schedule, and started to produce enough non-woven fabrics for the epidemic prevention and control. The output of non-woven fabrics in February was 3.5 times the usual output.
With the spread of the Novel coronavirus epidemic worldwide, the demand for masks is increasing. Meltblown cloth is the core filter layer in the middle of masks. It is known as the "heart" of masks and is the most scarce raw material for the production of masks and protective clothing. The market demand for meltblown cloth special materials is increasing, and the supply of meltblown materials is becoming increasingly tight.
It is understood that the production of meltblown cloth and conventional non-woven fabrics are very different. The melt fingers of meltblown fabrics are as high as 800-2000g / 10min, which is much higher than the melt fingers of existing non-woven fabrics. The higher the melt index, the thinner the drawn wire, and the diameter is as small as 1 to 5 μm, in order to meet the requirements of the melt-blown cloth for filtering bacteria and viruses.
“Can we use the industrial advantages to develop meltblown materials to alleviate the core materials of masks that are urgently needed for epidemic prevention and control?” Facing the needs of epidemic prevention and control, Guangzhou Petrochemical leaders attached great importance and instructed relevant departments to study and solve. Guangzhou Petrochemical has set up a research and development team to carry out formulation research, test analysis and scale-up experiments. Zhang Yingzhen, the director of the R & D center of the company's technology and quality department, organized a number of experiments on the formulation of meltblown non-woven fabrics, screened the formulation of additives, optimized the product performance, successfully came up with the formulation of meltblown non-woven fabrics, and overcome high The production of melt index polypropylene is difficult, and industrial production is quickly completed to meet the needs of epidemic prevention and control.
