With the epidemic still spreading around the world today, everyone has to wear a mask on their daily travels, leading to an expanding demand for meltblown fabric, the core key to manufacturing masks.
At present, more than 90% of the meltblown fabrics on the market are “sprayed” by meltblown fabric molds, with a typical mold nozzle diameter of 0.4 mm, or 400 microns. The meltblown cloth mold is a dense spout mold, in the work, these molds maintain the temperature at about 300 degrees Celsius, in the spout around the high-speed, hot airflow “blowing” the molten polymer sprayed, as a mask production, meltblown cloth mold cleaning sterilization problems can not be ignored, it is no exaggeration to say: the meltblown cloth mold It is no exaggeration to say that the cleanliness of meltblown fabric molds directly affects the production efficiency and mask quality of the whole industrial line.
So how to clean the meltblown cloth mold is better?
Melt spinneret mold special ultrasonic cleaning machine just can quickly solve the mold spinneret hole blockage, calcined carbon cleaning problems, is a professional meltblown cloth mold / spinneret / spinneret head / spinneret hat and other workpiece cleaning equipment.
What solvent is used for ultrasonic cleaning machine of meltblown cloth mold? What is the water temperature setting?
To clean meltblown cloth mold products, use ordinary tap water with degreasing cleaning agent. The suitable cleaning temperature of water is 50-70℃, especially in the cold weather, the temperature of cleaning liquid is low, the cavitation effect is poor, and the cleaning effect is also poor. Therefore, some cleaning machines in the cleaning tank outside the winding heating wire for temperature control. When the temperature rises, cavitation is easy to occur, so the cleaning effect is better.
Melt spraying machine mold cleaning method method is as follows.
The first step: mold high-temperature calcination, calcination of residual carbon, the use of meltblown machine mold cleaning machine with water-based degreaser cleaning
The second step: the use of meltblown machine nozzle special cleaning agent, with the meltblown machine mold special cleaning machine direct cleaning, dissolve the residual polypropylene
Step 3: Wait for a moment, after cleaning the mold can continue to work.
