Melt blown cloth spray humidifier improves the toughness of the melt blown cloth and does not become brittle. News is well known. Melt blown cloth is the "key layer" in the middle of the mask and the key to prevent virus droplets from having protective effects. It is called the "heart" of the mask. Therefore, the demand for meltblown fabric in the domestic market is very large, and more and more factories or enterprises have joined in the processing wave of meltblown fabric related products! It is understood that the most basic requirements for meltblown fabric on the market at present are 90%, 95% or 99% filtering effect, flexibility and strength
BFE99: bacterial filtration rate of 99%, virus filtration rate of 30%, generally used for surgical masks
Grade KN95: bacterial filtration rate of 99%, virus filtration rate of 95%, generally used for protective masks
You can understand your mood, but you must not rush to the doctor. You must find out the problem! Then, why does your meltblown cloth become so hard that it breaks when you tear it, and it is as fragile as paper? Usually, the texture and toughness of the newly sprayed meltblown cloth are very good on the day, and it will become hard and brittle after being put into the hands of customers for a day or two; The reason may be that the uneven wire spraying and insufficient air volume of the air cooler lead to uneven heat dissipation and internal stress, resulting in brittleness. It can be improved by adjusting the melt output of the extruder, adjusting the temperature of the hot air blower, and increasing the air volume of the cold air blower. You can also try to change the raw materials. The quality of PP melt blown materials is now uneven. The molecular weight distribution of the material is uneven. After the temperature is restored to normal, the stress causes the product to become hard and brittle. It also does not rule out its own equipment problems. After all, a production process involves many factors such as "human, material, law and environment"
In addition, insufficient moisture absorption of polypropylene fiber during melt blowing will affect the tensile and strength of polypropylene fiber. For this reason, in the production process of melt blown fabric, the corresponding auxiliary spray device is generally installed at the place 10 cm~50 cm below the spinneret, which is the combination of spray rapid cooling technology and air cooling technology, with better cooling effect. It can reduce the evenness of polypropylene fiber to below 0.2%, the elongation at break CV value and breaking strength CV value to below 0.3% and 0.4% respectively. In addition, a softener or toughener can be added in the spray device to conduct spray, which can greatly [increase the toughness of the melt blown cloth] and make the melt blown cloth obtain better strength. It is not easy to break, not hard, not brittle, and more flexible. And [increase the handle of the melt blown fabric] to make the melt blown fabric softer and smoother. Melt blown non-woven fabric softener enhances wire drawing strength
Nowadays, some melt blown cloth manufacturers or enterprises use nozzles to directly spray spray on the melt blown cloth production line. However, due to the large spray particles and poor uniformity, it is easy to form water stains on the melt blown cloth, and the size of spray is not easy to master. At the same time, some will use steam humidification or artificial watering, watering and other ways to supplement humidification, which seriously affects the production efficiency and quality of melt blown fabrics. In view of this, the electric appliance introduces a new type of auxiliary spray device for melt blown cloth machine--_ Melt blown cloth spray humidifier and ZS series ultrasonic spray humidifier can be added at any position on the production line, which is very convenient to install, and the use effect of spray is very good
_ Melt blown cloth spray humidifier and ZS series ultrasonic spray humidifier products use the principle of ultrasonic high-frequency oscillation to atomize water into 1-5 μ m ultrafine particles. The water mist is diffused into the air through the pneumatic device, so as to achieve the goal of uniform spray humidification; With air humidification, purification, and dust, cooling, dust and other purposes; For other humidification methods, melt blown cloth spray humidifier has the obvious advantages of [fine atomized particles], [low use energy consumption], [high atomization energy efficiency], and [fast humidification speed]: it can not only conduct uniform humidification in a larger space, but also conduct local humidity compensation in a special space, with high flexibility in use. Welcome to inquire the details of the melt blown cloth spray humidifier to improve the toughness of the melt blown cloth without becoming brittle

To sum up, the high efficiency of production and operation is the core for nonwoven and melt blown fabric manufacturers to reduce their comprehensive operating costs. In order to improve the production quality of non-woven fabrics and meltblown fabrics, the stability of workshop humidity is very important. As any non-woven fabric and meltblown fabric production enterprise knows, the impact of humidity on non-woven fabrics and meltblown fabrics is too high, the strength of non-woven fabrics and meltblown fabrics cannot be reached, and the humidity is too low, the non-woven fabrics and meltblown fabrics will be brittle, the breaking strength will drop far, and they are easy to be damaged. Therefore, use efficient and convenient spray humidification products--_ Melt blown fabric spray humidifier and ZS series ultrasonic spray humidifier are a problem that must be considered by non-woven fabric and melt blown fabric manufacturers
With the normalization of the melt blown non-woven fabric market and the tightening of quality standards, the melt blown non-woven fabric equipment has increasingly standardized the requirements for the auxiliary spray devices, especially the requirements for the installation space and production environment of the spray device. Whether it is natural cotton fiber or man-made polypropylene fiber, if you want to achieve high-speed and trouble free operation in the whole production process, it is essential to select a suitable spray device for spray humidification.
