When the epidemic first began, our circles of friends were brushed with masks, and many manufacturers of masks have earned real money. However, recently people found that the core material of the mask meltblown cloth is the hard currency, many speculators have no choice but to devote themselves to this mask-related industry chain, to originally have a good order of the meltblown cloth market has brought uncertainty. Recently, however, the news broke out somewhere: the suspension of hundreds of meltblown fabric manufacturers, this is why? Because of the quality problem. While meltblown fabrics have become a hot issue chased by capital and business, many manufacturers produce unqualified, substandard meltblown fabrics that do not meet the standards for medical masks N95 or even KN95, and many small workshops produce meltblown fabrics that do not even have the relevant test reports to prove.
So how to improve the quality of the mask meltblown fabric, it depends on its professional testing, such as respiratory assistance testing, filtration efficiency testing, etc. Only in this way can we improve the quality of the meltblown fabric production. The following is an introduction to the classification of meltblown fabric testing equipment and its testing standards.
1. Appearance, impurities, meltblown blocks, thin mesh, color difference, joint quality and other appearance quality inspection issues.
2. Longitudinal breaking strength, longitudinal and transverse breaking elongation, unit area quality deviation rate and other intrinsic quality testing problems.
3. Microbiological indicators such as bacterial colony count, fungal colony count, coliforms, pathogenic septicemia and other detection problems.
Today there are a lot of meltblown fabric testing equipment on the market, such as meltblown fabric particle filtration efficiency tester, meltblown fabric bacterial efficiency tester, ventilation resistance and differential pressure test tester, airflow resistance and breathing resistance tester, hydrostatic pressure tester, meltblown fabric permeability tester, etc., Today we are introducing one of the meltblown fabric Particle filtration efficiency tester, the following is introduced about the meltblown cloth filtration efficiency tester composition and its technical parameters in detail.
CW-HPC600A Handheld Laser Particle Counter is the original set of handheld and desktop printing in one of the highly sensitive laser dust particle counter. Its patent-protected design not only in the sensitivity, resolution and stability of the sensor technology is also ahead of international similar products. The unique multi-functional integrated design meets and facilitates the user's needs. It can accurately measure the number and distribution of particles in the environment in real time; various measurement parameters can be set, such as automatic real-time display, particle size selection, timing, delay and automatic repeat measurement, time, and date settings, data storage and printing, counting over the limit of the alarm light function.
