1, the proportion of non-oily particles is different.
90 meltblown cloth means filtering 90% of non-oily particles, and 95 meltblown cloth means filtering 95% of non-oily particles.
2. Different parameters
95 meltblown fabric is stronger than 90 meltblown fabric in nozzle, melting temperature, air volume and wind speed and electrostatic strength.
Extended data:
Meltblown cloth is the core material of mask. Melt-blown fabric mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 ~ 5 microns. Ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that meltblown fabrics have good filterability, shielding, heat insulation and oil absorption.
It can be used in the fields of air, liquid filter materials, isolation materials, absorption materials, mask materials, heat insulation materials, oil absorption materials, wiping cloths and the like.
On March 8, 2020, the State Council State-owned Assets Supervision and Administration Commission (SASAC) introduced that facing the blowout demand of mask core materials, the State Council State-owned Assets Supervision and Administration Commission (SASAC) guided and urged relevant central enterprises to speed up the construction of production lines and put them into production as soon as possible, so as to expand the market supply of meltblown fabrics and provide guarantee for epidemic prevention and control.
