Today, when the epidemic is still spreading around the world, everyone has to wear a mask for daily travel, resulting in an ever-expanding demand for meltblown cloth, the core key to making masks.
At present, more than 90% of meltblown cloths on the market are “sprayed” from meltblown cloth molds. The typical mold nozzle diameter is 0.4 mm, which is 400 microns. Meltblown cloth mold is a kind of mold with dense nozzles. When working, the temperature of these molds is maintained at about 300 degrees Celsius. There is a high-speed, hot air flow around the nozzle to “blow” the molten polymer, which is produced as a mask. The cleaning and sterilization of melt-blown cloth molds cannot be ignored. It is no exaggeration to say that the cleaning problems of melt-blown cloth molds directly affect the production efficiency and mask quality of the entire industrial line.
So how to clean the meltblown cloth mold better?
The special ultrasonic cleaning machine for melt blown machine mold can quickly solve the problem of mold spinneret hole blockage and calcined carbon deposit cleaning. It is a professional meltblown cloth mold / spinneret / spinneret / spinneret hat and other workpiece cleaning equipment.
What solvent does the meltblown cloth mold ultrasonic cleaner use? What is the water temperature setting?
To clean melt-blown cloth mold products, use ordinary tap water and degreasing cleaning agent. The suitable cleaning temperature of water is 50-70 ℃, especially in cold weather, the temperature of the cleaning liquid is low, the cavitation effect is poor, and the cleaning effect is also poor. Therefore, some washing machines wrap heating wires outside the washing tank for temperature control. When the temperature rises, cavitation is easy to occur, so the cleaning effect is better.
The method of cleaning the mold of the meltblown machine is as follows:
Step 1: The mold is calcined at high temperature, and carbon deposits remain after calcination. Use a special cleaning machine for meltblown molds and a water-based degreaser to clean
Step 2: Use the special cleaning agent for the nozzle of the meltblown machine, and directly clean it with the special cleaning machine for the mold of the meltblown machine to dissolve the residual polypropylene
Step 3: Wait for a while, the mold can continue to work after cleaning.
