Wholesale White Tourmaline Powder for Glaze Making/Coating/Non-Woven Fabrics
White Tourmaline powder application: meltblown cloth, non-woven cloth, masterbatch,mask etc.
Effect: Improving static electricity and improving filtration rate.
Size: 1um, 2um, 3um, 5um, 10um and nanometer level.
White Tourmaline powder can be made into melt-blown non-woven fabric by melt-blown method, and charged into electret through electrostatic generator under 5-10kv high voltage, which can improve fiber filtration efficiency. Because tourmaline has the function of releasing negative ions, it is also antibacterial.
In fact, the filtration performance of meltblown nonwovens is less than 70%. Merely relying on the mechanical blocking effect of three-dimensional fiber aggregates with fine fibers, small voids and high porosity is not enough. Otherwise, increasing the weight and thickness of the material will greatly increase the filtering resistance. Therefore, the electrostatic electret process is generally used to increase the electrostatic charge effect on the meltblown filter cloth, and the electrostatic method can improve the filtration efficiency, which can reach 99.9%-99.99%. That is, kn95 or higher.
Tourmaline powder is a necessary filter material for melt-blown electrostatic electret.
