Polyhexamethylene adipamide (Polyhexamethylene Adipamide, referred to as PA66) is a common chemical production raw materials, widely used in plastics, fibers and engineering plastics and other fields. Due to its special physical and chemical properties, polyhexamethylene adipamide needs to comply with certain safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safe storage and transportation specifications for polyhexamethylene adipamide.

1. Physical and Chemical Properties of Polyhexamethylene Adipamide

Polyhexamethylene Adipamide is a translucent or opaque Milky White crystalline polymer with high melting point, heat resistance and mechanical strength. It has good oil resistance, chemical resistance and electrical insulation, but it is flammable and decomposes at high temperatures to produce toxic gases.

2. safety storage specifications for polyhexamethylene adipamide

1. Storage environment: polyhexamethylene adipamide should be stored in a dry, cool, well-ventilated indoor environment, avoid direct sunlight and high temperature.
2. Storage container: A special sealed container should be used for storage to ensure that the container has good sealing performance and prevent leakage.
3. Storage identification: Obvious identification shall be set up in the storage area to indicate the name, danger and storage precautions of polyhexamethylene adipamide.
4. Storage management: Establish a strict storage management system and regularly check the stored poly (hexamethylene adipamide) to ensure that it is in good condition.

3. the safety of polyhexamethylene adipamide transport specifications

1. transport vehicles: should be used with dangerous goods transport qualification of special vehicles for transport, to ensure that the vehicle in good condition, in line with the relevant standards.
2. Transport packaging: Polyhexamethylene adipamide should be packaged with special packaging materials to ensure tight and firm packaging to prevent leakage during transportation.
3. Transportation identification: Obvious identification of dangerous goods shall be provided on the transportation vehicles and packaging, indicating the name, danger and transportation precautions of polyhexamethylene adipamide.
4. Transportation route: Choose a reasonable transportation route to avoid passing through sensitive areas such as densely populated areas and water source protection areas.
5. Transport personnel: transport personnel should be trained professionally in the transport of dangerous goods, with appropriate knowledge and skills.

4. emergency treatment measures

During the storage and transportation of polyhexamethylene adipamide, in case of leakage, fire and other accidents, the following emergency treatment measures should be taken:

1. Leakage treatment: in case of leakage, the leakage source should be cut off immediately, and special absorption materials should be used to clean up the leakage to avoid flowing into the sewer or environment.
2. Fire treatment: in case of fire, fire extinguishing equipment such as dry powder and foam shall be used immediately to extinguish the fire, and alarm and start the emergency plan at the same time.
3. Personnel rescue: If any person is injured, immediately move the injured person to a safe area and take necessary rescue measures.

In short, as a common raw material for chemical production, poly (hexamethylene adipamide) needs to strictly abide by relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment. At the same time, a sound emergency plan and management system should be established to improve the ability to respond to emergencies.
