pom聚甲醛原料:聚甲醛(英文:polyformaldehyde)熱塑性結晶聚合物。被稱為“超級鋼”或“賽鋼”,也被稱為聚甲醛。英文縮寫是POM。通常,通過甲醛聚合獲得的聚合物具有低聚合度并且易于熱解聚。它可用作有機化學工業和合成樹脂的原料,也可用作藥物熏蒸劑。pom聚甲醛原料優點1.機械強度高,剛性好;2.最高的疲勞強度;3.良好的耐環境性和耐有機溶劑性;4,抗反復沖擊能力強;5,使用溫度范圍廣(-40℃?120℃);6,良好的電性能;7.良好的彈性;8.自潤滑和耐磨性;9.極好的尺寸穩定性。pom聚甲醛原料缺點強酸腐蝕,耐候性差,粘附性差,熱分解和軟化溫度接近,氧極限指數小。pom聚甲醛原料用途:多聚甲醛是具有高甲醛含量的固體甲醛。它為固體顆粒形式,易于存儲和運輸。可以在較高溫度下轉化為甲醛蒸氣,可以輕松替代高濃度的甲醛來參與各種反應,這有利于化學合成,例如化學工業,制藥和其他工業領域,特別是在需要使用無水甲醛為原料。,用途廣泛。主要方面如下:(1)農藥:合成乙草胺,丁草胺和草甘膦;(2)涂料:合成高檔汽車涂料;(3)樹脂:合成脲醛樹脂,酚醛樹脂,聚縮醛樹脂,三聚氰胺樹脂,離子交換樹脂和各種粘合劑;(4)造紙:合成紙增強劑;(5)鑄造:除砂劑,合成鑄造膠;(6)養殖業:迅蒸汽消毒劑。(7)有機原料:用于制備季戊四醇,三羥甲基丙烷,甘油,丙烯酸,丙烯酸甲酯,甲基丙烯酸,N-羥基甲基丙烯酰胺,烷基酚,甲基乙烯基酮等。(8)其他:藥品和消毒。
