PP熔喷特种材料PP
医用口罩一般具有多层结构，通常称为SMS结构，且原料主要为聚丙烯（聚丙烯，PP）。从口罩材料来看，聚丙烯高熔体手指非织造布是最佳选择，可用于一次性手术服、床单、口罩、窗帘、吸液垫等诸多方面。数据显示，1吨高熔点手指纤维材料可生产约20万个防护口罩或5000套防护服，1吨聚丙烯医用透明材料可生产约8万个常规一次性注射器
熔融吹塑工艺是用高速高温气流吹塑由螺杆挤出的熔体，使熔体的细流以更高的速率拉伸，形成超细短纤维，然后堆积在网筒上的帘子上，形成连续的短纤维网，然后通过自粘或其他增强工艺制成无纺布
熔融吹塑非织造布的工艺也使用熔融纺丝的方法，即从纺丝孔挤出熔融细流成型纤维。然而，与纺粘法不同的是，熔喷法中使用的喷丝头在喷丝头孔的两侧都有专门设计的风道（空气缝）。加热后的高压空气从风管中吹出，形成熔体。细流被高速吸入，从而吹成超细短纤维。超细短纤维经喷丝板下方的冷风机冷却后，以极高的速率以负压喷射到纤维收集装置，主要是冷凝筛或成型鼓，以形成纤维网。最后，通过自粘或热粘合添加固定类型来获得无纺布
熔融吹塑聚丙烯特殊材料熔融吹塑工艺对聚丙烯材料的要求是：稳定的高流动性（熔融指数不是很高）、窄的分子量分布、低灰分、无其他产品残留、优良的纺丝性能等。然而，大多数聚烯烃制造商出厂时都有高熔融指数的聚丙烯，需要对其进行修改，以制作熔喷材料
PP Meltblown Special Material PPProduct: PP meltblown special material PPFeatures: Low odor,Low impurities,Low ash content,High filtration efficiency,Ultra high melt flow rate. PP Meltblown Special Material PP Product DetailsPP meltblown special material PP Medical masks generally have a multilayer structure, generally referred to as the SMS structure, and the raw material is mainly polypropylene (Polypropylene, PP). From the point of view of mask materials, polypropylene high-melt finger nonwoven fabric is the best choice, which can be used in disposable surgical gowns, sheets, masks, drapes, liquid absorption pads and many other aspects. Data shows that 1 ton of high-melt finger fiber material can produce about 200,000 protective masks or 5000 sets of protective clothing, and 1 ton of polypropylene medical transparent material can produce about 80,000 conventional disposable syringes. Meltblown process The melt-blowing process is to blow the melt extruded by the screw with a high-speed high-temperature air flow, so that the fine flow of the melt is stretched at a higher rate to form ultra-fine short fibers, which are then piled up on the curtain On the mesh drum, a continuous short fiber web is formed, and then a non-woven fabric is made by self-adhesion or other reinforcement process. The process of melt-blown non-woven fabrics also uses the method of melt spinning, that is, extruding the melt fine-flow forming fibers from the spinning holes. However, the difference from the spunbond method is that the spinneret used in the melt-blown method has specially designed air ducts (air slits) on both sides of its spinneret holes. The heated high-pressure air is blown out of the air ducts to the melt The thin stream is drawn at high speed, thereby blowing into ultra-fine short fibers. After being cooled by the cold blower under the spinneret, the ultra-fine short fibers are sprayed at a very high rate to the fiber collection device with negative pressure, mainly the condensate screen or the forming drum, to form a fiber web. Finally, the non-woven fabric is obtained by adding a fixed type through self-adhesion or thermal bonding. Meltblown polypropylene special material The requirements of the melt-blowing process on polypropylene materials: stable high fluidity (the melt index is not very high), narrow molecular weight distribution, low ash content, no other product residues, excellent spinning performance, etc. However, most polyolefin manufacturers leave the factory with high melt index PP, which needs to be modified to make meltblown materials.
