PTFE nano film mask can be washed and reused for 30 days
The emergence of the novel coronavirus has disrupted the medical-grade protection market. It is the Chinese New Year of 2020. How can the protection industry really release production capacity in a special period, and how to deploy to make up for the huge market gap has become the keen concern of the whole country. For ordinary citizens who are about to resume work, the most in short supply must be masks. It is reported that the masks that can play a role in virus protection mainly include medical surgical masks and N95 masks. The main material that brings virus filtration to these two masks is the inner filter cloth made of polypropylene which is extremely fine and electrostatically charged to capture dust.——Meltblown nonwoven. However, electrostatic adsorption masks have a huge weakness. The electrostatic content will gradually decrease with the production, packaging, delivery, transportation, and use, and the protective efficiency will decrease. To this end, the Chinese Society of Composite Materials proposed a new direction for the development of epidemic protection——PTFE nanofilm mask. Nano antibacterial masks are similar to ordinary medical masks, and also include outer layer, middle layer, inner layer, ear loops, nose clips, etc. The special feature is that the middle layer is composed of nano-membrane with smaller pore size (100-200 nanometers). , generally PTFE material. The PTFE film prepared by the unidirectional or biaxial stretching method has a spider web-like microporous structure on the surface, and has very complex changes in the three-dimensional structure, such as network connection, hole inlay, and pore bending, so it has excellent surface filtration. Function. Nano masks produced by using this material have the characteristics of high barrier efficiency, long service life, light and breathable, and are a new direction for the development of masks in the future. However, at present, PTFE nano-film masks cannot completely replace traditional masks due to price factors.
Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
