What do I need to pay attention to when transporting and storing plastic semi-finished profiles?
What you need to pay attention to during transportation and storage:
Requirements of storage environment:
The storage environment of plastic semi-finished profiles should have suitable temperature and humidity conditions to avoid adverse effects on their performance and quality. The suitable storage temperature is 20-30 degrees Celsius, and the humidity is controlled between 40-60%.
Dustproof and moisture-proof work should be strengthened. For storage containers of plastic products, coverings or cover materials can be used for protection to prevent dust and debris from entering. For bulk plastic products, well-sealed containers should be selected for storage to minimize the possibility of moisture exposure
Exposure of semi-finished plastic profiles to sunlight should be avoided as much as possible to prevent the ultraviolet rays in sunlight from adversely affecting them and reducing their performance. You can choose to store in a shaded warehouse or use a sunshade for protection
Storage method:
For plastic semi-finished profiles that are hard and not easily deformed, stacking storage can be used. In the process of stacking and storage, it is necessary to pay attention to the use of reasonable stacking height, to avoid excessive pressure on the plastic products; laying flat, to avoid tilting phenomenon between the plastic products; the use of appropriate shims between the different layers, evenly dispersed weight
For soft plastic semi-finished profiles, hanging storage is a better choice. This type of storage can avoid deformation and pressure on the products. In the process of hanging storage, attention should be paid to the use of appropriate hanging devices to ensure that the plastic products are hanging firmly; according to the length and weight of the products, reasonable arrangement of the hanging position and spacing, to avoid mutual extrusion; regular inspection of the condition of the hanging device to ensure its firmness and stability.
Expiry date management:
The establishment of material accounts and regular inventory, should be near the expiration date of the material in advance response, such as three months in advance to notify the production planners to arrange timely production. If possible, establish an electronic system for material in and out of account management and expiration date warning mechanism.
Loading and unloading protection measures:
In the transportation process, attention should be paid to the protection of plastic semi-finished profiles, especially some thin connecting plates, should try to avoid direct contact with other components, loading should be considered when the components of the stacking position, so as to avoid deformation of the components under pressure
Profile turnover car, work equipment, etc., all contact with the profile parts are protected by rubber pads, do not allow direct contact between the profile and steel components or other hard objects.
