”錫箔是用量很大的金屬箔，其的用途是制作紙錢和裝飾。關于錫箔的制造在古籍中也有報道。其加工制作也是采用層層疊合鍛打和退火，不同的是古人可能認識到了錫的表面易形成隔層(即氧化層)，因此不采取金屬片之間采用紙間隔的辦法。此后，又開發了蒸汽退火加熱技術。用蒸汽加熱可使溫度控制在略高于1℃，既可獲得很高的延展性，又可避免錫箔過度氧化。從近代起，我國傳統冶鐵術已無法滿足市場需要，盡管仍有地方生產“灌鋼”或“蘇鋼”，如在安徽的蕪湖、湖南的湘潭、四川的重慶、威遠等地人們還在使用這一傳統技術，但在全國范圍內，這一傳統的液體滲碳制鋼法不再成為制鋼主要手段。

PVC樹脂分解過程是由于脫HCL反應引起的一系列連鎖反應，后導致大分子鏈斷裂。防止PVC熱分解的熱穩定機理是通過如下幾方面來實現的。通過捕捉PVC熱分解產生的HCl，防止HCl的催化降解作用。鉛鹽類主要按此機理作用，此外還有金屬皂類、有機錫類、脂類及環氧類等。置換活潑的烯丙基氯原子。金屬皂類、脂類和有機錫類可按此機理作用。與自由基反應，終止自由基的反應。有機錫類和脂按此機理作用。與共扼雙鍵加成作用，共扼鏈的增長。
