Use of packaging bags
This packaging bag is divided into mechanical and manual packaging bags. For the mechanical packaging bags, because it is automatically controlled, the asphalt flow rate is reasonably controlled during the process of setting the asphalt filling process to avoid excessive speed and eroding the bottom of the packaging bag. . Control the strength, speed and other procedures of the manipulator so as to run at a constant speed, avoiding actions such as shock and vibration. For manual packaging bags: the bag holder should be smooth and flat without burrs. After folding the bag mouth, the center of the bag mouth is aligned with the asphalt filling port. After the asphalt filling is completed, the inner bag is tightened and the excess gas in the bag is released. , (90% or more) to prevent bag burst during placement. When sewing the outer woven bag, leakage is prevented because the inner membrane is punctured during the sewing process of the sewing needle. After filling the seam bag with asphalt, you can only grab the outer woven bag body at the seam of the seam sewing machine. It is forbidden to grasp the two corners of the bottom of the bag. ℃, the inner film bag is in a semi-plastic state, which is easy to tear and break. It can be said that the strength of the inner film bag is the most fragile at this time.) For transportation, the bag body cannot be dragged on the ground after asphalt filling, so as to avoid Scratch the bag body. Handle it with care during the shipping process. Do not touch the hard or sharp items. The bag should be broken to avoid rough handling. The cooling site should be flat, clean, and free of sharp objects such as gravel to avoid puncturing the bag. After the hot-filled asphalt is placed neatly, the asphalt and asphalt should not be stacked together, so as not to increase the cooling time and reduce the anti-aging time of the packaging bag. Due to the temperature at that time, it should be left for more than 24 to 48 hours, or left to cool for 8 hours after being naturally cooled, and then the asphalt can be completely solidified before the next factory shipment and palletizing storage.

Asphalt transportation and storage
When transporting to the transit site, timely replace the damaged asphalt, and replace the inner membrane and outer woven bag at the same time. Avoid rough loading and unloading during handling and transportation, avoid large impacts, collisions, and control the distance between the hopper and the loading and unloading surface when the loader is loading, not more than 1.5 meters
