Melt pressure sensor for meltblown cloth equipment

Melt-blown non-woven fabric, the full name of melt-blown non-woven fabric, is the key material for making medical masks. Its function is to prevent viruses from entering the body through the respiratory tract. The ultra-fine fibers of the melt-blown cloth have the function of electrostatic charging. In addition to blocking larger dust particles, they can also prevent fine dust, bacteria and viruses from being absorbed into the body through the electrostatically charged ions on the surface.

Meltblown cloth, as the core filter medium of masks, mainly uses its fine fibers, fluffy structure, and random overlapping with many voids and small voids. The fiber thickness is less than 10um, usually 1-4um. The reference size is ordinary The diameter of the hair is 50um~80um; the electret treatment will be carried out by the electrostatic effect, so that the particles of 0.3um or even more than 0.1um can be filtered;

Different regions and industries have different regulations on the size of the filtered particles, the filtration rate, and even the filtration pressure difference, and different standards have been formulated;

The production process principle of melt-blown cloth is very simple, that is, the polymer in the molten state at high temperature is sprayed out through small holes, hit on the receiving device, and overlapped into a thin layer, which is the non-woven fabric made by the non-woven method. , is the so-called meltblown cloth.

As a mainland Chinese company with a large number of engineers, they have expanded production or launched new meltblown cloth projects. Such a simple technology, such a good thing to save people, why not do it. Of course, for the production of meltblown cloth, controlling the thickness, uniformity, and fluffy effect of the fiber, avoiding the appearance of agglomerated polymers, and controlling the pressure and temperature of the melt are crucial technologies. Choose the correct pressure and temperature sensor, and install it correctly, some knowledge needs to take some time to learn.

In the production process of melt-blown cloth, slight changes in the process conditions such as melt temperature, pressure, melt flow, and hot air pressure of the melt equipment will cause deviations in the medical performance of melt-blown polyurethane elastic non-woven fabrics. In order to ensure high-temperature melting To ensure the stable operation of the body extrusion system and ensure the quality of non-woven products, it is necessary to use a high-temperature melt pressure sensor for monitoring to ensure the normal operation of the equipment.

At the front and rear ends of the metering pump, there are melt pressure sensors to achieve closed-loop pressure. It can keep the melt pressure constant and make the extrusion volume of each spinneret hole consistent. Melt pressure sensors play a vital role in improving the yield and output of melt equipment, improving production safety and protecting production equipment.

In the non-woven extrusion production process, to achieve the quality standard of the finished product, this requires the optimal control of the extrusion pressure equipment, and the melt pressure sensor is an important element to achieve this requirement.By arranging the melt pressure sensor and pressure control device at the connection of the mold inlet, the equipment can operate stably and the waste of materials can be reduced.A pressure sensor equipped on an extrusion line can measure the pressure at one point or the entire line. The specific scheme is such as: the melt pressure sensor is connected with the data recorder and the sound alarm device, and the processing parameters of the extruder can be adjusted by the processing control system. Such a combination is widely used in non-woven fabrics, non-woven fabrics, petrochemicals, chemical fiber spinning machines, plastics, rubber, extrusion equipment and other industries.
