Sacrificial adhesives are used throughout the manufacturing process and perform many tasks such as providing mechanical strength to ensure uniform sustainability, curing or bonding during manufacturing. The application range is very extensive and includes advanced ceramics, microelectronics, nanotechnology, metal welding and fuel cells.
NB-180 is an amorphous, colorless, thermoplastic polymer that is completely degradable and can be uniformly formed into benign products that are harmless to the environment, making it suitable for use in high-performance environments. Its purity and low ash residue make the NB-180 an ideal sacrificial adhesive for precision micro/nano-scale devices.
The NB-180 burns cleaner than its competing products. The residual value of ash is also well below five parts per million. Based on 3% binder usage, the final part has less than one percent ash residue. Lower residual values ​​mean lower defective rates and other quality issues in manufacturing.
Compared to similar products on the market today, NB-180 can also be degraded at relatively low temperatures. For example, it can be completely degraded at 250 degrees in air and begins to degrade at 180 degrees. This degradation temperature is at least 50 degrees lower than the currently used adhesives. Complete decomposition can be achieved at 300 degrees in inert gases such as nitrogen, argon, and hydrogen.
Easy-to-use refractory anchor bricks. Including the anchoring brick body, the middle of the left side of the upper surface of the anchoring brick body is provided with a triangular prism-shaped hanging groove, one of the side surfaces of the hanging groove is located on the upper surface of the anchoring brick body, and one of the bottom surfaces of the hanging groove is located on the right side of the anchoring brick body. The lowermost end of the hanging groove is provided with hanging holes penetrating the left and right ends of the anchor brick body. By implementing the present invention, the following beneficial technical effects can be obtained: the hanging piece is connected to the hanging hole through the hooks on both sides, and the refractory anchor brick can be rotated relative to the hanging piece through the setting of the hanging groove, but the rotation is restricted by the hanging groove , making the refractory anchoring brick more convenient to use, improving the service life of the refractory anchoring brick and reducing the material of the anchoring brick; when the hanging piece rotates to the limit position, the hanging groove and the hook are close to each other, and the contact area is large, preventing the hanging piece and the refractory anchoring brick from being damaged.
