Mask meltblown cloth equipment | Quickly Provide Mask Production Equipment

Now that the new coronavirus is sweeping the world, it is imperative to fully expand the production of masks. At present in China, the equipment for producing PP meltblown fabrics is in short supply. Due to benefited from intensive cultivation in the extrusion industry for nearly 30 years, with the support of many friends in the industry, we have expanded production capacity and now introduce the mask production eqipment to the market. All kinds of equipment for producing PP meltblown cloth with high stability and reliability, with high output and high cost performance, welcome to consultation.

The production of polypropylene PP medical-grade masks with excellent filtration capacity needs to go through the following three main production steps.

The first production step is to feed the polypropylene PP raw material, mixed with a certain proportion of free radical initiator (DCPD), lubricant (Erucyl amide) and antioxidant, into a feeding hole of a parallel twin screw extruder to be compounded, to get a ultra-high melt index MFI 1500 which is suitable for the raw material to make mask fabric by a melt-blown process way, referred to as the high melt index PP melt-blown material. Our company can provide users with detailed formula percentage of compounding PP melt-blown material, it is free.

The second production step is to feed PP meltblown raw material, which or purchased, or self-made, mixed with a certain stabilizer, whitening agent and masterbatch, into a feeding hole of a single screw extruder. With a cooperation of auxiliary devices such as netting, metering pump, spinneret, and winder, PP melt-blown fabrics with different widths are manufactured. 

The layout of the production process components is as follows:

According to the different widths of the meltblown fabric and the different output, our company can provide a multi-specification single-screw extruder with L/D30~33, and different auxiliary machines can be configured according to different requirements of users. The delivery period of PP melt blown fabric extruder of all specifications is within 40 days.
