北京科技大學的學者采用座滴法測定固液間接觸角,分別對鎂碳質基片及基片中的兩種主要組元與LF精煉渣之間的潤濕性進行了研究,并從潤濕性角度研究了鎂碳磚損毀機理。研究表明,在精煉溫度下,熔渣對石墨均呈不潤濕狀態,溫度越低越不容易潤濕。而熔渣對MgO組元呈完全潤濕狀態。熔渣與鎂碳質基片間的接觸角在溫度為1460~1480℃時存在明顯轉折,在轉折點溫度以下,MgO和碳的反應受到,熔渣對基片保持不潤濕狀態。

全丁同體鈣鋅穩定劑,其穩定性平u加T性都較上述2種穩定劑芹得多,能用于加TPVC—C管材、管件。沖擊改性劑由丁氯化聚氯乙烯樹脂中的氯含景較高,氯具囪較大的極性,如果在酉己方中/f作有效的抗沖改性,所生產的管材、管件抗沖擊性能極差,毫無實用價值。有效的抗沖擊改性是PVC—C管材、管件配方設計的關鍵之一。常用丁PVC-C管材、管件的抗沖改性劑都可以用于PVC—C管材、管件,如CPE,MBS,ABS,抗沖ACR發的PVC/高分子抻性休接枝共聚樹脂等,但它們住配辦巾所產生的效果足骨芹別的。
