Mechanical anchor bolts and chemical anchor bolts are currently the most important standard parts on the market at this stage. In the eyes of many non-professionals, they should be similar, but in fact they are still different from each other. In the beginning, there are different ways of engineering reinforcement. The chemical anchors mainly rely on putting the analytical chemical tube into the hole, or pressing a part of the medicine in the container into the hole according to the pressure hot melt gun, and put it into the hole. The inner screw will support the cracking of the medicine tube, and the screw can bite into the wall hole fiercely by the pre-tightening force caused by the medicine tube. The mechanical anchor bolt uses the basic concept of the mechanical equipment password padlock key of the screw to anchor the fixed card with steel reinforcement.
  
Different chemical bolts have different construction methods, which will cause differences in the construction period. Chemical anchors are used to anchor the steel bars with analytical chemicals, so it takes a lot of time to make the chemical drugs abundant. Solidification, and exceeding the solidification temperature of the analytical chemical drug can easily cause the reduction of the quality of the reinforcement of the steel bar. For construction projects where the construction time is too tight, chemical anchors are not a good choice.
  
Mechanical anchor bolts are not easy to have such difficulties. If the drilled steel bar is well anchored, it can be used immediately. The quality of the steel anchoring will not be damaged at all, which can save a lot of time. Also, in terms of the difficulty of the operation process, if you want the chemical anchor to ensure a stronger anchoring effect of the steel bar, you must eliminate the dust and residue in the clean and tidy hole, so that the analytical chemicals and the board can be touched to the greatest extent. , It has the role of steel anchoring, and it is necessary to skillfully introduce analytical chemicals into the holes. This is all to improve the difficulty of steel anchoring.
  
Compared with mechanical anchors, chemical anchors have the advantages of corrosion resistance, low temperature, aging, water resistance, stable load in the short and long term in humid geographical environment, high-quality seismic grade characteristics of buildings, no swelling stress field, and small row height spacing. Therefore, both chemical anchor bolts and mechanical anchor bolts have different characteristics, and they should be purchased according to different application requirements.
