aluminum nose clips for face masks

Aluminum nose clips for face masks are exquisitely processed. First, apply strong adhesive, choose a strong adhesive and environmental protection hot melt adhesive, evenly apply on the back of aluminum alloy plate. Aluminum nose clips for face masks is bonded with environmental protection hot-melt adhesive. When the hot-melt adhesive is bonded with non tarpaulin, the dosage of each part is 0.02-0.05g. Because the hot melt adhesive is 100% solid, the hot melt adhesive becomes molten after heating, and the touch gas is dry and solid on the cold surface. The connection time is short, the bonding is fast, and the environmental protection is strong. It is suitable for N95 and kn95 masks.
1. Appearance:
Hollow aluminum nose clips for face masks have the function of effective fulcrum, so the surface of aluminum nose clips for face masks should be smooth without obvious oil stains, and should be as straight as possible without bending. If there are too many oil stains on the surface, it will hurt the children who are applying hot melt adhesive, thus damaging the expected effect of aluminum nose clips for face masks. If it is found that aluminum nose clips for face masks have more oil stains during operation, it can be cleaned with alcohol.
2. Type:
Aluminum nose clips for face masks are divided into high frequency machine welding aluminum nose clips for face masks and cold drawing. As the cold drawn aluminum nose clips for face masks have low oxidation resistance and are not good-looking, the market sales are gradually replaced by high-frequency welding aluminum strips, so it is not recommended to buy them.
3. Total width:
At present, the total width of aluminum nose clips for face masks on the market is 5.0 mm-26.0 mm, and it is necessary to select the appropriate model according to the specification of insulating glass window. In most cases, x.5 models and specifications are more common, such as 5.5A, 8.5a, 11.5a. Protective mask aluminum plate.
4. Wall thickness:
Wall thickness refers to the thickness of the inner wall of aluminum nose clips for face masks, which can be divided into sheet metal bending and non sheet metal bending. The thickness of aluminum nose clips for face masks that can not be bent by sheet metal is 0.2mm-0.29mm; the thickness of aluminum nose clips for face masks that can be bent by sheet metal is 0.3mm-0.35mm. The thicker the aluminum nose clips for face masks, the less the bending loss.
In addition, the thickness of aluminum nose clips for face masks is 0.2mm-0.25mm. Aluminum nose clips for face masks in this model and specification range are hand-made, which can control the cost. The aluminum plate with thickness of 0.23mm-0.29mm can be made by hand and used by machines. If it is machine equipment and film, it is recommended to use aluminum nose clips for face masks with thickness more than 0.21mm. The aluminum plate with thicker wall has stronger plasticity and is not easy to be damaged by machinery and equipment.
5. Aspect ratio:
The aspect ratio of aluminum nose clips for face masks is fixed in the middle of 5.5mm-7mm. The higher the aspect ratio is, the thicker the aluminum plate is. The national industry standard aspect ratio of aluminum nose clips for face masks is 7mm, and the error is within + - 0.02mm.
