In summary, due to the adoption of the technical scheme, the beneficial effects of the invention are as follows:
1. the advantages of the nanotechnology improved masking tape include:
the strength and durability are remarkably improved: the nanotechnology-modified masking tape has significantly higher tensile strength and durability due to the addition of the nanoreinforcement layer. The use of carbon nanotubes or nanofibers greatly enhances the structural integrity of the tape, making it more suitable for applications requiring high strength and durability, such as heavy duty packaging or long-term use in harsh environments.
Excellent adhesive force: the improved adhesive layer is designed to be distributed in a shape of a plurality of transverse stripes which are arranged in parallel along the length direction of the adhesive tape, so that the adhesive force of the adhesive tape is improved, and the adhesive force of the adhesive tape on different surfaces (such as rough, smooth or irregular surfaces) is also improved.
Flexibility and adjustability increase: the combination of the nano reinforcing layer and the specially designed adhesive layer provides extremely high flexibility and adjustability for the masking tape. The user can more easily cut or adjust the tape according to specific needs while maintaining its basic properties.
Cost savings while the addition of nanomaterials may increase unit cost, overall use costs are reduced due to their high strength and durability. Because the improved tape is not easily broken or lost in tackiness, the need for more frequent replacement is reduced. And the high strength and durability of the use of carbon nanotubes or nanofibers means that the tape has a longer service life, thereby reducing waste generation and more frequent replacement, and having a certain environmental friendliness.
The application range is widened: because of the remarkable improvement of strength, durability and adhesive force, the masking tape with the improved nanotechnology can be applied to more high-end and special demand scenes, such as aviation, medical equipment, automobile manufacturing, precision electronic products and the like.
2. The adhesive tape coiling device of the invention has the advantages that:
the balance performance is excellent: the number and uniformity of the distribution of the balancing means ensures the stability of the device during operation. The design of the tensile member and the roof member further enhances the balance performance of the apparatus. In particular the use of extension springs and hold down springs, provides additional resilience and stability.
