The Key of Meltblown Cloth for Mask Heart: Resident Masterbatch Dongguan Dechuang Chemical Co., Ltd. has developed and produced 1500 special melt-blown non-woven fabric material for melt-blown PP mask. The same number of mobile phone WeChat is 1382709711. Managers are welcome to inquire and discuss business. A kind of modified plastic is produced by blending homopolymerized fiber-grade polypropylene as raw material, auxiliary special rheology modifier and other additives. It has the advantages of environmental protection, innocuity, low odor, narrow molecular weight distribution, very stable ultra-high fluidity and good melt-blown processing performance. It is applied to the production of M melt-blown non-woven fabric (commonly known as the heart of mask) in the middle filter layer of medical mask. For medical masks, this layer is the core part of the electret-treated electret meltblown cloth with electret master batch and electret-treated electret-treated electret meltblown cloth. Only a lot of electric charges on the electret-treated meltblown cloth can effectively adsorb 0.3 micron non-oily small particles with the same electric charges, usually requiring more than 95%, which can only be tested by professional instruments. Some manufacturers also use two layers of 25-28g electret-treated meltblown cloth to achieve the effect of 50-60g electret meltblown cloth! 1-200326141301314.jpg Polypropylene is used as a base material, and a special auxiliary agent is used, so that the auxiliary agent is uniformly dispersed in the master batch; and 3 to 5 percent is added in the spinning process of the melt-blown cloth, so that the density and depth of charge trapping energy traps in the melt-blown non-woven cloth can be effectively increased, and the comprehensive filtering effect and thermal attenuation resistance of the melt-blown non-woven cloth can be improved. Under the condition of the same fiber fineness and gram weight, the non-woven fabric product resistance is reduced, and the filtering effect of the non-woven fabric product is improved. The development of resident masterbatch is currently produced by only a few domestic enterprises. Dongguan Dechuang Chemical Co., Ltd. is an independent research and development manufacturer of 1500 melt-blown PP materials with resident masterbatch, many of which are used by melt-blown cloth factories. With the large-scale production of melt-blown cloth in China, the market for resident masterbatch is currently in a state of shortage. Dongguan Dechuang Chemical Co., Ltd. developed and produced 1500 special melt-blown non-woven fabric material for melt-blown PP mask. The same number of mobile phone WeChat is 1382709711. Managers are welcome to inquire and discuss business. Polypropylene is used as the base material, imported special additives customized by Germany are used, and special equipment and technology are used to manufacture the additives to achieve submicron dispersion effect in the masterbatch. The use of the product can increase the density and depth of charge trapping energy traps in the melt-blown non-woven fabrics and achieve the performance of improving the comprehensive filtration efficiency and thermal attenuation resistance of the melt-blown non-woven fabrics. Under the condition of the same fiber fineness and gram weight, the resistance of the non-woven fabric product is reduced, and the filtering effect of the non-woven fabric product is improved at the same time
