The safety storage and transportation specification
of recycled PC
1. Introduction

recycled PC (polycarbonate) is a polymer material widely used in the field of chemical production, with high mechanical properties, thermal stability, optical transparency and other advantages. However, due to its special chemical properties, recycled PC has certain safety risks during storage and transportation. In order to ensure the safety of recycled PCs, it is essential to have a strict set of storage and transportation specifications.

2. the physical and chemical properties of recycled PC

recycled PC is made of waste PC plastic products through crushing, cleaning, plasticizing and other processes. The physical properties are similar to native PCs, but there may be some performance differences. Recycled PC has good heat resistance, cold resistance, impact resistance, dimensional stability and other characteristics, can be used to manufacture a variety of plastic products. However, recycled PC contains some additives and impurities produced during the regeneration process, which may have a certain impact on its performance and safety.

3. the safety of recycled PC storage specifications

1. Storage environment: Regenerated PC should be stored in a dry, ventilated, dark environment, avoid direct sunlight and high temperature.
2. Storage container: special plastic containers or bags should be used for storage to avoid contact with metal or other chemical substances.
3. Storage period: Regenerated PCs should be used within their specified storage period to avoid expired use.
4. Safety management: fire-fighting equipment and safety signs should be set up in the storage area, and regular safety inspections should be carried out to ensure storage safety.
Safety transportation specifications for
4. recycled PCs

1. Transport vehicles: Special freight vehicles should be used for transportation to ensure that the vehicles are in good condition and meet relevant transportation standards.
2. Packaging requirements: The recycled PC should be packaged in special bags or containers to ensure that the packaging is tight and firm to prevent damage or leakage during transportation.
3. Transportation route: A reasonable transportation route should be selected to avoid passing through harsh environments such as high temperature and humidity to ensure stability during transportation.
4. Safety identification: Transport vehicles shall be provided with obvious safety identification and dangerous goods identification so as to take corresponding measures in case of emergency.

5. Regenerative PC Safety Specification for Use

1. Pre-use Inspection: Before using a regenerative PC, a quality inspection should be conducted to ensure that it complies with relevant standards and regulations.
2. Protection during use: In the process of using recycled PC, necessary protective measures should be taken, such as wearing gloves, masks, etc., to avoid direct contact or inhalation of harmful substances.
3. Post-treatment: After using the regenerated PC, the remaining materials should be properly handled to avoid discarding or discharging at will, causing environmental pollution.

6. regeneration of PC safety regulatory norms

1. regulatory authorities: should establish a special regulatory department for the regeneration of PC production, storage, transportation and use of the process of comprehensive supervision.
2. Laws and regulations: Relevant laws and regulations should be formulated to clarify the production, storage, transportation and use standards of recycled PCs, and severely crack down on illegal activities.
3. Training and education: The training and education of relevant personnel should be strengthened to improve their awareness of the safety of recycled PCs and their operational skills.

7. conclusion

recycled PC as an important raw material for chemical production, its safety has an important impact on the production process and product quality. In order to ensure the safety of recycled PCs, it is necessary to formulate strict regulations from many aspects such as storage, transportation and use, and take effective regulatory measures. By strengthening management and technical training, improving the safety awareness and operation skills of relevant personnel, the safety risk of recycled PC can be reduced to the greatest extent and the smooth progress of chemical production process can be guaranteed.
