Meltblown non-woven fabric use: Because the fiber produced by meltblown technology is very fine, and the meltblown fabric has a large specific surface area, small voids and large porosity, it has applications such as filtration, shielding, heat insulation and oil absorption Characteristics are difficult to possess in nonwoven fabrics produced by other separate processes. Therefore, melt-blown non-woven fabrics are widely used in medical and industrial masks, thermal insulation materials, filter materials, medical and sanitary materials, oil-absorbing materials, wipes, battery separators, and sound insulation materials. Jianlian melt blown cloth production line runs stably, with high yield and high efficiency. The melt blown cloth produced is uniform, strong, air permeable, non-toxic and tasteless, and meets environmental protection standards. Manufacturing widths: 1.6 meters, 2.4 meters, 3.2 meters, 4.2 meters. Through the practice of multiple production equipment, the overall technical indicators have reached the international advanced level of similar products.
The core raw material of masks, the production process of melt blown cloth is: raw material---->melt extrusion---->filtration (melt blown cloth change screen filter) ---->metering (melt blown cloth melting Body pump)---->air heating and compression---->melt blowing---->netting---->winding. The main function of the melt pump in the melt blown cloth production line is to accurately measure, control the output and the fineness of the fiber, and deliver the melt to the spinneret continuously and evenly. The melt blown cloth special melt pump provided by Jianlian melt blown cloth production line has the advantages of stable output pressure, improved product quality, increased extrusion output, and reduced unit energy consumption.
The upstream raw materials of the mask industry are mainly polypropylene and ethylene oxide. Among them, melt blown cloth made of polypropylene is the most scarce, and the shortage of melt blown cloth is mainly due to its production equipment. The mask machine used in the next supply and demand is easier to expand. According to news reports, the spinneret and fan, the key components of the meltblown cloth production equipment, need to be imported. Under normal circumstances, the procurement cycle is 8 months, and the installation and debugging cycle is 2 months, which is the bottleneck in the bottleneck. According to media reports, the market price of meltblown cloth for masks has risen from 18,000 to 19,000 yuan/ton in late 2019 to 150,000 to 200,000 yuan/ton, and short-term orders have been saturated.
From a technological point of view, it is not difficult to produce ordinary masks. The main problems are at two ends: upstream in the industrial chain, petrochemical raw materials and materials need to be supplied. From a downstream point of view, companies that have recently turned to mask production need to master the necessary technical and professional standards and production and management processes for mask production. The biggest bottleneck: melt blown cloth. Melt blown cloth production equipment has a high technical threshold, and the core sprinklers and other accessories are imported from Germany and Japan. Statistics show that if work is fully resumed, the daily domestic demand for masks will be 500 million, and the total production capacity will be 7,285.
