It is well known that the news of non-woven fabric humidifier and melt blown non-woven fabric production line spray device is affected by the epidemic this year, and the demand for masks is huge; As its core raw material, a small piece of melt blown non-woven fabric, which was unknown and unknown in the past, has grown into a hot "cloth gold" in the market, which is really "one cloth is hard to find". However, there are also many melt blown non-woven fabric processing plants or enterprises across the country that produce melt blown non-woven fabrics that become hard and brittle after being put out for one night, without toughness; Moreover, there are many reasons for such problems as rough and unsmooth cloth surface: for example, uneven thread spraying and insufficient air flow of the air cooler cause uneven heat dissipation and internal stress, leading to brittleness; Another example is that the melt finger of the melt blown material is too high, such as the melt finger of 3000. In this way, the material has little strength like catkins in the process of spraying
What's more, this phenomenon is related to the high processing temperature. Moreover, just after being made, the melt blown nonwoven fabric still has a temperature, especially the melt blown nonwoven fabric machinery with large drum for material collection, which does not even have a fan. The temperature of the melt blown nonwoven fabric is high after winding. Under the high temperature environment, the more flexible and tenacious the plastic is, and the brittle it will become after cooling. In addition, it is also related to the relative humidity in the local area of the production line of the melt blown nonwoven processing plant or enterprise workshop, but this factor is often ignored by many people! Many people may find that the toughness and softness of melt blown nonwoven fabrics made in the morning or evening are better, while those made at noon are worse, which is why! So, how to solve this problem? In fact, it is also very simple. You only need to configure the corresponding spray humidifier in the local area of the production line of the melt blown non-woven fabric workshop to carry out spray humidification
Generally speaking, the relative humidity of the local environment of the production line in the melt blown nonwoven processing plant or enterprise workshop is kept within the most appropriate range, but the requirements for the local environment humidity of the production line in the workshop are slightly different for each different process. Therefore, it is necessary to meet the humidity requirements of melt blown nonwoven products and semi-finished products in each process on the local production environment of the workshop production line. At present, several humidification measures are commonly used by domestic melt blown non-woven fabric processing plants or enterprises: for example, some melt blown non-woven fabric processing plants or enterprises sprinkle water or spray water on the local area of the production line of the workshop, or often mop the floor with a wet mop. Although this can ease the situation slightly, it will make the floor messy and affect the production efficiency of the local area of the production line of the entire workshop, Only using air evaporation can not play a good role in spray humidification
In some workshops, the local area of the production line is heated to generate steam, which can also achieve a certain effect of spray humidification, but this not only cannot meet the requirements, but also increases the cost. The power required for electric heating is very large and simple, which requires several KW, and fuel heating is even more impossible. Some melt blown non-woven fabric processing plants or enterprises use air conditioners for humidification in some areas of the workshop production line, which is a relatively advanced method. However, the investment in air conditioners is relatively large, and the maintenance costs in the later period are also high, and the humidification effect is not very good, According to the survey, the humidification of air conditioners in local areas of production lines in workshops of different sizes is far from meeting the requirements for humidity in local areas of production lines in melt blown nonwoven processing plants or enterprise workshops
In fact, the most simple and effective way to increase the air humidity in local areas of the production line of melt blown non-woven fabric processing plants or enterprise workshops is to use industrial spray humidifiers, but the problem has arisen again; At present, there are many kinds of industrial spray humidifiers on the domestic market, such as high-pressure spray, water vapor mixing, ultrasonic, electrode, evaporative, etc; Among them, the atomization effect of ultrasonic spray humidifier is the best of the four, and the atomized particles are less than 5 μ m. The spray humidification effect is excellent. More than 90% of the fog can conduct heat exchange with the air, which can rapidly increase the air humidity without blocking, dripping and other phenomena; To this end_ Melt blown non-woven fabric processing plant or enterprise spray humidifier and ZS series ultrasonic industrial spray humidifier have become a necessary spray humidification and dust reduction equipment in local areas of production lines of many large melt blown non-woven fabric processing plants or enterprise workshops in China
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 non-woven fabrics, 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 nonwoven fabric] to make the melt blown nonwoven fabric obtain better strength. It is not easy to break, not hard, not brittle, and more flexible. And [Increase the handle of melt blown nonwoven fabric] to make the melt blown nonwoven fabric more soft and smooth. Melt blown non-woven fabric softener enhances drawing strength
Nowadays, some melt blown non-woven fabric production plants or enterprises use nozzles to directly spray spray on the melt blown non-woven fabric production line. However, due to the large spray particles and poor uniformity, it is easy to form water stains on the melt blown non-woven fabric, and the size of spray volume is also difficult to master. At the same time, some will use steam humidification or manual watering, water spraying and other ways to supplement humidification, which seriously affects the production efficiency and quality of melt blown non-woven fabrics. In view of this, the electric appliance introduces a new type of auxiliary spray device for melt blown non-woven fabric machine--_ Melt blown non-woven fabric humidifier and ZS series non-woven fabric production line spray device 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 non-woven fabric humidifier and ZS series non-woven fabric production line spray device products use the principle of ultrasonic high-frequency oscillation atomization to atomize water to 1-5 μ M of ultra fine particles, through the pneumatic device, the water mist is diffused into the air, so as to achieve the purpose of uniform spray humidification; With air humidification, purification, and dust, cooling, dust and other purposes; For the melt blown non-woven fabric humidifier with other humidification methods, it has the obvious advantages of [fine atomized particles], [low energy consumption], [high atomization energy efficiency], and [fast humidification speed]: it can not only uniformly humidify a large space, but also partially compensate the humidity in a special space, with high flexibility.

◎ Model selection reference: There are many factors to be considered in the model selection of melt blown non-woven fabric humidifier, such as the indoor space volume, ambient temperature, equipment heat, ventilation, and air conditioning exhaust will affect the indoor environment humidity and humidification effect. Generally, a certain margin should be left when calculating the humidification amount, that is, the corresponding humidification amount should be increased, In addition, the humidification amount required in the space and the corresponding model of melt blown non-woven fabric humidifier shall be comprehensively calculated from low humidity humidification to ideal humidity range. See more non-woven fabric humidifiers, and the details of the spray device of the melt blown non-woven fabric production line can be found in: Hangzhou Parkoo Electrical Equipment Co., Ltd.
_ Melt blown non-woven fabric humidifier and ZS series non-woven fabric production line spray device have good humidification effect, fine atomized particles, stable operation and high cost performance. In addition, there will be no water dripping during the spray humidification process, which will not affect the output and quality of melt blown non-woven fabrics and non-woven fabrics. It can also improve work efficiency and increase benefits. With the electrostatic electret device, you can make the melt blown non-woven fabrics and non-woven fabrics produced by your melt blown machine and non-woven machine more soft, full of toughness, and greatly improve the filtering efficiency, reaching 90+and 95+detection standards
In addition, when choosing the melt blown non-woven fabric to support the electrostatic electret device -- high-voltage electrostatic generator, it must be a negative charge reaction. Many friends bought a small power 120KV electrostatic electret generator to make it cheaper. The real power is only 30~50KV. This electrostatic adsorption force is extremely weak. After about two days, the static electricity is completely lost, and the filtering effect returns to the original point. It is recommended to use a 120KV high-power electrostatic electret generator (the measured power is 80KV~90KV), Electrostatic adsorption can last for more than half a year. Generally, regular large units will directly use a 150KV electrostatic electret generator. Of course, the effect is needless to say, but the price is relatively high
To sum up, for any melt blown nonwoven processing plant or enterprise, it is necessary to master this "degree" in the process of taking corresponding measures to spray humidification on the melt blown nonwoven production line; Otherwise, it will lead to poor electrostatic electret effect; Therefore, only by maintaining an environment with appropriate humidity and relatively constant humidity, can we effectively ensure the smooth production in local areas of the workshop production line and the improvement of the quality of meltblown nonwoven products, increase the toughness and flexibility of meltblown nonwoven fabrics, avoid problems such as hardness, brittleness and tearing, and effectively ensure the health and safety of workers
