In the context of 2020 COVID-19 epidemic, thousands of melt-blown factories with uneven levels emerged. From the beginning just look at the appearance to concerning the internal data, from focusing on filtration efficiency to requiring low resistance, from just looking at the initial data to asking for a loading test, customers are becoming more and more picky in this oversupplied market. However, top melt blown fabric manufacturers mainly focus on the following 4 points.
1.Filter material of the same grade with adequate efficiency.
2. Same filtration efficiency with lower resistance.
3. Persistent filter efficiency and loading test qualified.
4. Material uniformity.
Therefore, high temperature aging test, loading test, oil aerosol test, long-term stability of batch products, etc., indicate the rigour of filter material users.
Based on the above requirements, Science Purge strictly select filter material and committed to strict management.
