Understand the meltblown cloth production equipment, meltblown extruder detailed explanation Melt-blown cloth is the use of high-speed hot air flow to draw a thin stream of polymer melt extruded from the nozzle hole of the die, thereby forming ultra-fine fibers and collecting them on the condensed screen or roller, and at the same time bonding themselves to become Meltblown nonwoven fabric.
Due to the particularity of the melt-blown cloth production process, as a raw material for melt-blown cloth, it must meet the following requirements. The high melt index should be greater than 400g/min, leaving a narrow ash with a relatively low molecular weight distribution. The melt index of the melt blown raw material is too low, the melt viscosity is large, and the extruder needs to provide a
Dry goods sharing, the reason why the melt-blown cloth becomes brittle the next day The new pneumonia epidemic is both a crisis and a big exam. With the rapid spread of the New Crown epidemic, meltblown fabrics have grown from obscure mask raw materials to the hot "cloth gold" in just a few months. Many manufacturers have the problem of becoming brittle the next day after the meltblown fabric
Overview of melt blown cloth equipment at present, there are many large and small production lines on the market, ranging from 300 to 3200mm wide, and the configuration is also very different. The main core components of melt blown cloth equipment are: extruder, mold, roots blower (or air compressor), electret equipment and other core components, such as screen changer, metering pump and other acc
The design principle and structure of the meltblown machine equipment is not complicated, but the maturity of all equipment must go from raw to mature, and experts also come from rookies. Although many equipment manufacturers used to make plastic machines, they have never made meltblown machines. So the equipment you bought is actually the first product of others. To put it bluntly, the 650 and 80
