中文摘要 | 特殊機能紙之研究是以化學附加方法或物理添加法,將化學藥劑添加或附加特性於紙上賦予紙張特殊機能,以增加利用並提高紙的附加價值為本實驗之目標。本研究進行抗燃紙的製備,以磷酸及尿素反應製成磷酸銨鹽,在磷酸氫二銨之緩衝溶劑中浸入纖維素基質如紙張、紙漿、紗布、棉布等,經絞乾、熟成、洗滌、乾燥等處理製備成抗燃性材料。試驗結果顯示,在磷酸/尿素摩爾比1/3之條件下,磷酸/尿素的濃度在0.2 M/0.6 M以上,所製備之抗燃紙漿可達抗燃二級以上,磷酸/尿素在濃度0.5 M/1.5 M以上則無論殘燄、殘燼、炭化長均達抗燃一級。濃度在0.1 M /0.3 M以下時幾乎無抗燃性。各種材料中製成抗燃紙之抗燃性質以紙漿為最佳,其次為紙張、紗布、棉布等均可達到抗燃二級以上,厚紙亦較薄紙為佳。加速劣化試驗顯示抗燃紙在高溫、高濕(85℃,85% RH,7天)之狀態下紙張之強度性質及抗燃性有些許低下,乾式加速劣化(105℃, 24 h) 後其抗張強度仍有對照組之 70%,抗燃性質仍維持在抗燃二級之標準,顯示此抗燃紙具相當優良之耐久性。另外,防�蚽�之製備是以雙環己烷硝酸氨(dicyclohexyl ammoniumnitrate) 以不同製備法如塗佈、含浸、噴霧等製備防�蚽�,並同時進行接觸性防蝕試驗及防�蚽�對環境的抵抗,結果顯示以含浸法所製備防�蚽�包裝之鐵製樣品在高溫(50℃, 100% RH)的條件下,經四個月後仍維持相當優良之防�蚸坒遄A經加速劣化後之防�蚽�仍維持相當優異之防�蚸吽C |
英文摘要 | Special functional papers are papers imparted with specific properties through the addition of chemicals or physical modifications. These conversion processes enhance paper utilization and increase the value of the paper products. For this study, flame-resistant paper was prepared by impregnating cellulosic substrates, such as paper, pulp, gauze, or cotton fabric, with the reaction products of phosphoric acid and urea in a buffered solution of ammonium phosphate, after which the materials went through the procedures of wringing dry, curing, rinsing, and drying. At a phosphoric acid/urea molar ratio of 1/3 and at respective concentrations of 0.2 M and 0.6 M or more, the products could meet or exceed the requirements of flame-resistant class II. Treatment concentrations below 0.1 M/0.3 M were ineffective in imparting flame resistance. If the concentrations of phosphoric acid/urea used were 0.5 M: 1.5 M, then class I standards were achieved for all parameters. Among different substrates, pulp gave the best result, while paper, gauze, and cotton fabric could also reach the class II threshold. Thick paper performed better than did thin ones. Accelerated-aging conditions of high temperature and humidity (85℃ and 85% RH, for 7 d) for flame-resistant papers were shown to be detrimental to paper strength and flame resistance; but the products could still meet class II requirements. Accelerated aging with dry method (105℃, 24 h) reduced paper tensile strength by 30%, but it still retained class II flame resistance. Rust-proof paper was prepared by coating, impregnating, or spraying dicyclohexyl ammonium nitrate (DICHAN) onto paper substrates. The treated paper was tested for rust-proofness and its interaction with environmental factors. The results show that iron ingots wrapped with impregnation-treated rust-proof paper could maintain good rust-proof conditions even after 4-mo exposure under 50℃ and 100% RH. Accelerated-aged rust-proof paper could still retain good rust-proofness. |
