標準解讀
GB/T 44194-2024《增材制造 金屬粉末再利用技術(shù)規(guī)范》是中國關(guān)于增材制造領(lǐng)域中金屬粉末再利用的技術(shù)標準。該標準詳細規(guī)定了在增材制造(也稱為3D打?。┻^程中使用金屬粉末進行再利用的質(zhì)量控制、檢測方法、處理流程以及環(huán)境保護等方面的要求,旨在促進資源的高效循環(huán)利用,同時確保再利用金屬粉末滿足增材制造的品質(zhì)與安全標準。具體要點包括:
-
適用范圍:明確了本標準適用于采用激光熔融沉積、電子束熔融等增材制造技術(shù)過程中產(chǎn)生的金屬粉末的回收、篩選、檢測及再利用過程,涵蓋了多種常見的金屬材料,如鈦合金、鋁合金、不銹鋼等。
-
術(shù)語和定義:為確保標準的準確執(zhí)行,首先對增材制造、金屬粉末再利用等相關(guān)專業(yè)術(shù)語進行了明確界定,為后續(xù)條款的執(zhí)行提供了統(tǒng)一語言基礎(chǔ)。
-
質(zhì)量控制:詳細闡述了金屬粉末在回收和再利用前后的質(zhì)量控制要求,包括粉末的物理性能(如粒度分布、形狀、流動性)、化學(xué)成分穩(wěn)定性及污染控制等,確保再利用粉末能維持原有性能,減少對最終產(chǎn)品性能的影響。
-
檢測方法:規(guī)定了對回收粉末進行檢測的具體方法和標準,如使用光譜分析檢測化學(xué)成分,采用激光粒度分析儀測量粒度分布等,以科學(xué)、準確的數(shù)據(jù)評估粉末是否符合再利用標準。
-
處理流程:描述了從粉末收集、清潔、篩選、檢測到重新包裝的一系列標準化處理步驟,強調(diào)了每一步驟的操作規(guī)范與注意事項,確保處理過程既高效又安全。
-
環(huán)境保護:強調(diào)了在金屬粉末回收再利用過程中應(yīng)采取的環(huán)保措施,比如粉塵控制、廢棄物處置等,以減少對環(huán)境的影響,符合可持續(xù)發(fā)展理念。
-
記錄與追溯:要求建立完善的記錄體系,對金屬粉末的來源、處理過程、檢測結(jié)果及再利用情況等進行詳細記錄,確保全程可追溯,提升質(zhì)量管理的透明度和可靠性。
-
安全與健康:提出了在粉末處理過程中保障人員安全與健康的措施,包括但不限于個人防護裝備的使用、操作區(qū)域的通風(fēng)條件以及應(yīng)急響應(yīng)計劃的制定。
