Read： 625 Time：12months ago Source：Transform the World with Simplicity

PBT (polybutylene terephthalate) is an important raw material for chemical production, which is widely used in engineering plastics, fibers and films. Due to its special chemical properties, PBT needs to comply with strict safety regulations during storage and transportation to ensure the safety of personnel and the environment. This paper will detail the safe storage and transportation specification of PBT.

1. the physical and chemical properties of PBT

PBT is a semi-crystalline thermoplastic resin with high strength, hardness, heat resistance and chemical resistance. Its molecular structure contains ester groups, which are easily eroded by water, acids, alkalis and other substances, so special attention should be paid to protection during storage and transportation.

2. PBT safety storage specification

1. The storage place should choose a dry, ventilated and cool place to avoid direct sunlight and high temperature environment.
2. The storage container shall be a special container with good sealing performance to avoid contact with air and moisture.
3. During storage, the tightness and integrity of the container should be checked regularly to prevent leakage and damage.
4. The storage area shall be provided with obvious safety signs and warning signs, and open fire and smoking shall be prohibited.

3. PBT safety transportation specifications

1. Before transportation, check whether the packaging is intact to ensure that the container is well sealed to prevent leakage and damage.
2. During transportation, it should be loaded and unloaded lightly to avoid severe vibration and collision and prevent package damage.
3. Transportation vehicles shall be provided with corresponding safety measures such as fire prevention, explosion prevention and leakage prevention to ensure the safety of transportation process.
4. In the process of transportation, avoid mixing with oxidants, acids, alkalis and other substances to prevent chemical reactions.

4. PBT leakage emergency treatment specification

1. In case of leakage, the leakage source should be cut off immediately, mixed with sand, dry lime or soda ash and recycled to the special waste treatment site.
2. Avoid leakage into the sewer, drainage ditch and other restricted space, to prevent pollution to the environment.
3. The personnel handling the leakage should wear professional protective gloves and masks to avoid direct contact with the leakage.
Precautions for the safe use of
5. PBT

1. During the use of PBT, care should be taken to maintain good ventilation and avoid prolonged exposure to high concentrations of PBT vapor.
2. Operators should wear professional protective gloves, masks, goggles and other personal protective equipment to prevent direct contact with PBT.
3. In the process of using PBT, avoid contact with oxidants, acids, alkalis and other substances to prevent chemical reactions.

6. conclusion

PBT as an important chemical production raw material, in the process of storage and transportation need to strictly abide by the safety norms to ensure the safety of personnel and the environment. By understanding the physical and chemical properties of PBT, mastering its safe storage and transportation specifications, as well as leakage emergency handling specifications and safe use precautions, we can effectively ensure the safety of the production process and avoid accidents and losses caused by improper operation. Therefore, in the actual production process, relevant personnel should strictly abide by relevant regulations and standards to ensure the safe use and management of PBT.
