The setting time of chemical anchors depends on various factors, the most important of which are the ambient temperature and humidity. Generally, the higher the temperature, the shorter the setting time, and the higher the humidity, the longer the setting time. In addition, the thickness and size of the drug will also affect the setting time. Thicker drugs have longer setting times, and places with larger drug surface areas have longer setting times.
The temperature of the chemical anchor substrate is suitable for -5℃ to 40℃, so the setting time of chemical anchors is different:
When the substrate temperature is -5℃~0℃
1. When the substrate temperature is -5℃~0℃, the installation time of the chemical anchor is 40 minutes, the initial setting time is 90~150 minutes, and the setting time is 8 hours.
When the substrate temperature is 0℃~10℃
2. When the substrate temperature is 0℃~10℃, the installation time of the chemical anchor is 25 minutes, the initial setting time is 50~90 minutes, and the setting time is 6 hours.
When the substrate temperature is 10℃~25℃
3. When the substrate temperature is 10℃~25℃, the installation time of the chemical anchor is 15 minutes, the initial setting time is 35~50 minutes, and the setting time is 4 hours.
When the substrate temperature is 25℃~40℃
4. When the substrate temperature is 25℃~40℃, the installation time of chemical anchor bolts is 6 minutes, the initial setting time is 15~35 minutes, and the solidification time is 2 hours.
When the substrate temperature is higher than or equal to 40℃
5. When the substrate temperature is higher than or equal to 40℃, the installation time of chemical anchor bolts is 4 minutes, the initial setting time is 7 minutes, and the solidification time is 1 hour.
Note: Too short solidification time will cause aging, cracking and deformation of the object. Too long solidification time will affect the original strength of the object. Therefore, the appropriate material should be selected according to the scene and environment of drug use. At the same time, corresponding preparations need to be made before construction, including checking humidity and temperature, and selecting the appropriate drug thickness and model.
