KN90 Respirator factory

Because investment in meltblown production lines has a threshold in terms of capital and technology, it is not easy to achieve overnight. They are familiar with the production characteristics and precision processing requirements of plastic raw materials, with unique hot air flow structure design and higher production capacity. In this project, sincere and Hongda are strong in joint innovation. Liang Bin, Jingcheng is the only company in the industry that has flow channel simulation and analysis technology and continuous optimization in combination with actual use.

Compared with the most advanced melt-blown die heads abroad, Jingcheng products are comparable to them, and there is no difference in the quality of the final coil, and compared with the delivery time of more than 6 months abroad, Jingcheng also has a short supply cycle Advantages, generally 3-4 months, the service is more timely and convenient, with fast after-sale response speed. Beijing Petrochemical will KN90 Respirator factory 2 melt-blown fabric production lines and 3 spun-bonded fabric production lines, and strive to achieve partial production of melt-blown non-woven fabrics on March 8. China's spun melt nonwovens production capacity and output are located in the world Forefront.

Cloth is the most critical layer of filter material in the middle layer of the mask. Liang Bin said. The high-temperature, high-speed and high-pressure hot air stream draws the melt wire while hot, and sprays it onto the load-bearing sieve plate. After more than 30 years of rapid development, a variety of more mature spun melt nonwoven production processes have been formed. In the production process of melt-blown non-woven fabric (mask cloth), the pp special material is extruded and plasticized (melt temperature is about 310 degrees),

then enters the die head flow channel, evenly distributed, and then enters the spinneret, spinneret There are dense pores of melt filaments, and there are many pores that spray high-temperature air in the same direction at high speed. In the melt-blown equipment, the melt-blown die head is one of the core components to realize the wire drawing of the polymer. The company has been providing support for customers in this field.' Mr. I believe that in this Sinopec project, Jingcheng will also hand in an excellent answer sheet.In yesterday's hot report
