Зарад, які захоўваецца ў EM-1, можа быць уніпалярным рэальным зарадам (прасторавым зарадам), уведзеным звонку, або дыпольным зарадам, утвораным упарадкаванай арыентацыяй дыполяў у палярным дыэлектрыку, або абодвума тыпамі зарадаў адначасова.
EM-1 can increase the ability of electrostatic adsorption and negative ion sterilization of the mask to effectively block droplets, dust, viruses, etc. below microns. At the same time, under the same fiber fineness and gram weight, the resistance of non-woven products can be reduced, and the filtration efficiency of non-woven products can be improved at the same time.
The charged melt-blown cloth can more effectively filter the Staphylococcus aureus bacterial aerosol in the droplets. Therefore, to meet the bacterial filtration efficiency greater than 95% and meet the respiratory resistance not exceeding 49Pa, it is necessary to use an electrostatic melt-blown cloth. At the same time, it can reduce the resistance of non-woven products under the same fiber fineness and gram weight.
EM-1 is a kind of electret masterbatch applied to PP melt-blown cloth. It can effectively absorb the free charge generated during electret, and maintain the charge ability after electret treatment for a long time.
One of the key benefits of using EM-1 electret masterbatch in PP melt-blown cloth production is its ability to absorb the free charge generated during the electret treatment process. This helps to maintain the charge ability of the material for a longer period of time, which can improve its filtration efficiency and performance over time. By maintaining the charge ability of the material, EM-1 can help to ensure that the PP melt-blown cloth remains effective in capturing and filtering out small particles and pollutants, even after repeated use or exposure to various environmental conditions.| характарыстыка | значэнне | блок | метад выпрабаванні |

To improve the charge retention rate, lower decay value and prolong charge retentionperiod.
To improve the filtration efficiency of melt-blown non-woven fabric.
EM-1 - гэта электрэтная маткавая сумесь, нанесеная на тканіну, выдуваную з расплаву ПП.
