The size of the mining air duct will vary depending on the condition of the tunnel. Some coal mines have different tunnel sizes. If you encounter a small part of the tunnel, make a mining air duct with a large or small head. In this case, the construction will be carried out here. Then the device will not be affected by the hairdryer. There are also many customers who choose to go from large to small in order to save money, because the price of the hair dryer with a smaller diameter will definitely be cheaper.
Because the natural factors, human factors and equipment factors of the site where the mining hair dryer is used make the mining hair dryer extremely easy to be damaged, so the hair dryer glue is a necessary product.
If the hairdryer is made of rubber and needs to be polished because it is relatively thick, neoprene is generally used.
If the hairdryer is made of PVC-coated cloth, its physical and chemical properties are very similar, so we recommend using Geely Warwick hairdryer resin glue.
Pay attention to the following matters when repairing:
1. The surface of the air duct must be wiped clean, and no dust must be left. Especially there is a lot of coal dust underground, so it must be wiped clean.
2. There should be no moisture on the surface of the hair dryer. Since resin glue is a volatile glue, the surface of the dryer is moist, and the more it affects the volatilization, the worse the bonding effect will be.
3. When repairing, you need to apply glue on both the hairdryer surface and the repair material surface, and glue them when the surface is not reflective.
4. Where possible, the bonding surface can be heated. The temperature can fully integrate the resin glue and the surface of the fabric.
When the repair is completed, be sure to seal the unused glue. Due to the volatile nature of the resin glue, failure to seal will cause the glue to become completely ineffective due to volatilization.
If the hair dryer still leaks air over a large area, it should be scrapped and cannot be used again.
