flexible aluminum strips for face masks

Flexible aluminum strips for face masks are used to fit the edge and face of masks, which can improve the protective ability of masks. Therefore, the role of flexible aluminum strips for face masks can be imagined, but how to stick aluminum strips well also determines the quality of masks to a certain extent.

The masks that need to be pasted with flexible aluminum strips for face masks are generally N95 type masks, and glue must be used for pasting, except for those with built-in nasal bridge strips, hot-melt glue is not required. Now the working principle of the aluminum strip bonding machine on the market is basically the same - first glue the aluminum strip, and then press the aluminum strip to the non-woven mask at 90 ℃. It should be noted here that the melt tank temperature of the glue applicator should be 175-185 ℃, the roller temperature should be 160-165 ℃, and the melt tank temperature of the external heating machine should be 175-180 ℃.

After knowing how to paste flexible aluminum strips for face masks on N95 masks, it can be seen that there is no complex operation, the operation can be done quickly with machines, and the quality of masks produced by mechanization can also be guaranteed. Of course, the premise is that the cloth, hot-melt adhesive and ear straps are good. In addition, according to the difference of production efficiency, the hot melt adhesive used should be relatively fast drying and will not back stick, so that the aluminum strip can be firmly pasted to the surface of the mask. After the aluminum strip is separated from the mask, the flexible aluminum strips for face masks can evenly leave non-woven materials at the gluing place, which indicates that the gluing is uniform and the bonding strength is uniform, The pressing effect is very good. On the contrary, during the use of the mask, the bridge of the nose may be pressed and bent for many times, and local glue opening may occur, affecting the coincidence between the mask and the face.

With the novel coronavirus pneumonia epidemic, the demand for respirator is increasing. A good respirator is becoming more important than ever. How to stick flexible aluminum strips for face masks is another consideration for the overall quality of masks. Pasting the flexible aluminum strips for face masks is a guarantee for the quality of the mask, which also strengthens its protective effect and ensures the health of the wearer.
