Exposure of Sainuo melt-blown material production formula
Since the outbreak of the COVID-19, masks and other medical protective equipment have been in short supply throughout the country. From the perspective of the mask structure, medical surgical masks generally have three layers,Both inner and outer layers are non-woven fabrics, and the middle fil...Read more -
Pigment dispersion process
The pigment dispersion process consists of three steps: wetting, dispersing, and stabilizing. During the wetting process, the air and water vapor on the surface of the pigment are replaced by the resin solution, and the dispersing agent, especially the low molecular wetting and dispersing agent...Read more -
Application characteristics of polyethylene wax in road marking paint
Polyethylene wax has a high softening point, which can improve the heat resistance of road marking paint; Low viscosity, adjustable to improve leveling; Good flow performance, conducive to construction and improve construction efficiency; High hardness, wax is distributed in the coating film to...Read more -
Causes of white spots on blown film
The reason for the white spots on the blown film is due to the fact that during the extrusion ofthe blown film, the calcium carbonate agglomerates failed to open and the dispersion was uneven. In order to disperse the calcium carbonate particles in the masterbatch uniformly into the matrix pl...Read more -
