Several factors affecting the quality of meltblown cloth? Recently, net red meltblown fabrics have exploded, and many meltblown fabric manufacturers have questions: PP raw materials are no problem, the machine is operating normally, and the final meltblown fabrics produced by professional inspection agencies cannot meet the 95 standard. Why is this? Factors affecting the quality of meltb
Why do the meltblown fabrics you produce always fail to meet the 95 standard? Recently, I received a lot of calls to consult PP raw materials, the machine is operating normally, and the melt-blown cloth produced by the professional inspection agency can not meet the 95 standard. Why can't it reach the 95 standard? Today I will give you the puzzle! The melt-blown fabric do
Analysis on the maintenance work of melt-blown cloth extruder Everyone knows that the melt-blown cloth extruder has been used for a long time, and there will be various problems that require our maintenance. Therefore, the equipment is usually repaired on time, reducing the probability of equipment problems. Therefore, the maintenance work of the equipment is very important. Now let’s ta
How to produce qualified meltblown cloth, experience sharing. What does it take to produce N95? One machine, the second master, the third process, and the fourth melt-blown material. However, the current market models are quite confusing, and the artillery machine is flying all over the sky. Many friends have consulted. Can the artillery machine improve the quality of the meltblown clot
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
