STORAGEPRACTICES 储存操作规范
包装要求
原厂密封包装不得拆封，使用PE/铝箔袋或真空罐。多件包装需分隔，避免材料间污染（如PU与NBR不可混装）
库存管理
先进先出原则：超过12个月未使用的库存需重新检验。定期检查：每6个月检查硬度、表面状态（目视 ^{+} 硬度计）
运输防护
使用抗震泡沫箱，避免跌落、挤压。
禁止与放射性物质、化学品同车运输。
失效密封件的处置
轻度老化（表面微裂纹）：可降级用于非关键部位。严重老化（体积膨胀、断裂）：按危险废物处理，禁止直接丢弃
Packaging requirements
The original sealed packaging shall not be opened, and PE/aluminum foilbags or vacuum cans shall be used.
Multiple packages need tobe separated to avoid contamination between materials (e.g. PU and NBR cannot be mixed)
Inventorymanagement
First-in,first-out principle:Inventory that has not been used formore than12 months needs to be re-inspected.
Periodic inspection: Hardness and surface condition are checked every 6 months (visual hardness tester)
Transportprotection
Use a shock-resistant foam box to avoid falling and squeezing.
It is forbidden to transport radioactive materials and chemicals in the same vehicle.
Disposaloffailedseals
Mild aging (surface microcracks): can be downgraded for non-critical areas. Severe aging (volume expansion,fracture): Treat as hazardous waste, and direct discarding is prohibited
