Meltblown

When the mask becomes a hot word, when the market is hard to find, when there is a mask machine that cannot buy the meltblown cloth, when the epidemic situation comes suddenly ...
While you are still in a trance, many people are already acting. The savvy business once had the ability to perceive thousands of years, so it is no wonder that wealth is in the hands of a few people. Because too many people are all sentient beings, they are the foreshadowing, also, there is no ordinary people where can stand out from the crowd. Because of this sentence, investment has risk, wealth and risk coexist, and the size of the pressure resistance determines your success and failure coefficient.
Since the beginning of the first month, I have received countless calls, mask machines, mask melt-blown cloth machines, mask nose bridge machines, out of stock, out of stock, on the one hand, the market is in short supply, on the one hand, it takes a period of production, and decisive people are now counting It's time for money, hesitant people will always answer the phone and say, is it too late to use the device at this time?
In the latest news, everyone knows that the domestic epidemic control is basically okay, but the foreign epidemic situation is so serious that we surpassed our imagination. A young foreign trade brother found me a customer who asked me to introduce my production mask. He had orders for tens of thousands of N95 .. Someone has long aimed at foreign markets. With the outbreak of the epidemic, it is estimated that masks will become the standard for everyone in the future. According to the one-time theory, this amount is still huge! We are an extruder equipment manufacturer, not a fan, not wanting to make huge profits, just in the face of disaster, we can do what we have the ability to do.
Ran Goose, when everyone was talking about masks, friends made a speech in the group, intriguing: crazy, all crazy, Jiujin old lady holding a banana fan, said to Qijin: crazy ... ..
Seriously: The main material of melt-blown cloth is polypropylene (PP), which is a kind of ultra-fine electrostatic fiber cloth with a fiber diameter of about 2 microns. It is also called medical mask meltblown fabric, meltblown nonwoven fabric, and mask fabric on the Internet. This fabric is one-tenth the diameter of the outer layer of the mask and can catch dust. When the virus droplets are close to the meltblown cloth, they will be absorbed by the static electricity on the meltblown cloth and will not be able to penetrate. Therefore, it is a necessary raw material for the production of filter masks.

Melt-blown non-woven fabric has the advantages of good uniformity, high filtration efficiency and strong barrier ability. Mainly used in medical materials, filter materials, clothing accessories, diapers, sanitary napkins, battery separator materials, etc.

Meltblown fabric is a kind of non-woven fabric. Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers, without warp and weft, and are named because of their appearance and certain properties similar to woven fabrics. At present, there are many processing technologies for non-woven fabrics, such as spunbond, melt-blown, hot-rolled and spunlace. Among them, the non-woven fabric made by melt-blown method is called melt-blown non-woven fabric. The melt-blown method refers to a spinning method in which a polymer melt that has just been extruded is rapidly stretched and solidified by high-speed hot air flow.
The non-woven fabric produced by the melt-blown method has finer fibers, larger surface area, and better filtering, shielding, heat insulation and oil absorption properties, which are unmatched by non-woven fabrics produced by other processes.
Process flow of melt-blown non-woven production line
Polymer preparation --- Melt extrusion --- Metering pump --- Melt-blown die head assembly --- Melt fine flow drawing --- Fiber cooling --- Auxiliary network --- Static electret --- Reinforced finished product





The melt-blown fabric is produced by the melt-blown process. Its equipment mainly includes: screw extruder, melt pump, screen changer, melt-blown device, winding device machine, air system (heat fan and heater), etc. The function of the screw extruder is to melt the sliced material; the function of the melt pump is to accurately measure, control the output and the fineness of the fiber, and continuously and uniformly transport the melt to the spinneret. The role of the screen changer is to filter out impurities in the melt to avoid clogging the spinneret holes. The function of the winding device is to pack the melt-blown cloth into rolls. The function of the air system (heat fan and heater) is to provide the temperature and pressure of the hot air used in the spinning air flow stretching.
