標(biāo)準(zhǔn)解讀

《GB/T 2994-2008 高鋁質(zhì)耐火泥漿》與《GB/T 2994-1994 高鋁質(zhì)耐火泥漿》相比，在多個方面進(jìn)行了修訂和完善。首先，新版本對標(biāo)準(zhǔn)的適用范圍進(jìn)行了調(diào)整，明確了其適用于以高鋁礬土熟料為主要原料制成的耐火泥漿，并且增加了對于不同使用溫度等級產(chǎn)品的具體要求。其次，關(guān)于技術(shù)要求部分，2008版增加了對產(chǎn)品化學(xué)成分的具體規(guī)定，特別是Al2O3含量的要求更加嚴(yán)格；同時，對物理性能指標(biāo)如耐火度、線變化率等也提出了更高的標(biāo)準(zhǔn)。此外，新版還改進(jìn)了試驗方法，比如細(xì)化了試樣制備步驟，更新了某些測試條件或設(shè)備要求，使得測試結(jié)果更為準(zhǔn)確可靠。在檢驗規(guī)則上，新標(biāo)準(zhǔn)進(jìn)一步規(guī)范了出廠檢驗和型式檢驗的內(nèi)容與頻次，確保產(chǎn)品質(zhì)量穩(wěn)定可控。最后，包裝、標(biāo)志、運輸及貯存等方面也有相應(yīng)調(diào)整，增強(qiáng)了信息透明度和物流安全性。這些變化體現(xiàn)了行業(yè)技術(shù)進(jìn)步以及對產(chǎn)品質(zhì)量控制水平提升的需求。
