The mystery of dacromet coating
First, let's focus on a special coating called Dacromet. Dacromet treatment is a new type of metal surface treatment technology, it is different from the traditional electroplating or hot dip plating, but the use of zinc powder, aluminum powder, chromate and a variety of additives composed of paste coating, through impregnation, baking and other processes, on the metal surface to form a layer of dense, with good adhesion and corrosion resistance coating. This coating can not only effectively isolate the erosion of moisture, oxygen and corrosive media, but also maintain long-term anti-corrosion ability in harsh environments, providing a solid protective barrier for Dacrox hexagonal flange semi-threaded cement anchors.
Hexagonal flange design wisdom
Then look at its structural design - hexagonal flange. This design not only increases the contact area between the anchor bolt and the mounting surface, improves the stability of the installation, but also facilitates the use of tools such as wrenches for fastening, simplifying the installation process. The presence of the flange also allows the anchor to distribute the pressure evenly when stressed, reducing local stress concentration and thus extending the service life. In addition, the hexagonal shape design is also easy to store and transport, reducing the risk of damage due to collision or extrusion.
Unique advantage of half thread
The design of half thread is another highlight of Dacromet hexagon flange half thread cement anchor. Compared with the full-threaded anchor bolt, the semi-threaded structure reduces the contact area with the cement slurry while maintaining sufficient anchoring force, reduces the resistance during installation, and makes the anchor bolt easier to be screwed into the predetermined position. In addition, the half-thread is also easy to adjust the embedment depth of the anchor bolt to ensure installation accuracy and meet the needs of different working conditions.
Application scenarios of cement anchors
Semi-threaded cement anchors are widely used in all kinds of construction projects, especially in the case of high-strength connection and fixing, such as curtain wall installation, steel structure connection, equipment foundation fixing, etc. In the exterior wall decoration of high-rise buildings, they firmly fixed a piece of curtain wall panels on the main structure to resist the invasion of wind and rain; In bridge construction, they are an important link between the bridge body and the pier to ensure the safe passage of the bridge. Whether it is cold in the north or wet in the south, Dacrossa hexagonal flange semi-threaded cement anchor can contribute to the safety and stability of construction projects by virtue of its excellent performance.
Precautions for installation and maintenance
However, any quality building material needs to be properly installed and maintained to perform at its best. When installing the semi-threaded cement anchor bolts with Dacromet hexagonal flanges, ensure that the diameter, depth and verticality of the drilling hole meet the design requirements, and avoid using too large or too small bits to avoid affecting the anchoring effect. At the same time, when injecting cement slurry, the ratio and injection amount of slurry should be controlled to ensure that the anchor bolt can be completely wrapped in the slurry to form a firm anchor solid. During use, the fastening state of the anchor bolt should also be checked regularly. If loosening or corrosion is found, it should be handled in time to avoid safety hazards.
