Recently, researchers from the Fraunhofer Institute in Germany have developed a new type of fiber that can detect the intrusion of thieves. According to the researchers, the outer layer of the fiber is coated with a layer of silver, which is then integrated into a mesh and finally connected to a microcontroller. Once it is detected that someone has destroyed the weak current generated by the web, the controller will send a warning message to the house owner.
In addition to the above-mentioned feature, this smart fiber will also be able to ensure the safety of the user's road car inspection or banking, jewelry stores and museums.
According to researchers at the Fraunhofer Institute, the cost of this smart fiber is relatively low compared to other materials. Moreover, it can also be reduced to any size.
Nails for concrete are called cement nails. Cement Nail, commonly known as Steel Nail, is a nail, using carbon steel production, material has 45 steel or 60 steel, after wire drawing, annealing, nail, quenching and other processes processed, so the texture is relatively hard. Its function is to nail in some of the harder other nails can not nail on the object, because the material and ordinary nails are very different, is a special nail. The Cement Nail`s hardness is very big, is thick but short, pierces the Chisel ability to be very strong. CATEGORIES: Cement Nails Poles have a sliding rod, ruled, twill, spiral, bamboo, and so on, the general is a straight or sliding pole. According to different classification, cement nails can also be divided into: Black Cement nails, blue cement nails, color cement nails, countersunk head cement nails, K cement nails, t cement nails, galvanized cement nails and so on.
Home Concrete Wall nails nails several ways: 1, with cement nails, as the name implies is designed specifically in the concrete wall or brick wall and other hard medium nail things. 2. However, cement nails are sometimes not so good, if some walls really can not nail cement nails, expansion Bolts or expansion bolts, no matter how hard the wall it can handle. 3. However, when using expansion bolts or expansion bolts, an auxiliary tool is needed, which is the electric drill.
4. The head of the drill corresponds to the type of expansion bolt, so be sure to have a drill.
