style="text-indent:25px">鋁合金噴涂型材的前處理通過除去表面油污、塵埃、氧化皮后，再形成一層鈍化膜，該膜不僅能增強耐腐蝕性，而且能提高涂層與基材的附著力。傳統(tǒng)的前處理采用六價鉻鈍化工藝（即鉻化），眾所周知，鉻化工藝以其完善的工藝操作性及****的性能在該領域占據(jù)著極其重要的地位，但六價鉻系重金屬（具有很強的毒性），其應用領域受到越來越多的限制。因此各國都在不斷地進行無鉻鈍化工藝的研究，目前在批量應用的無鉻鈍化工藝有Zr-Ti系無鉻鈍化膜、硅烷處理、稀土金屬鈍化膜以及陽極氧化處理等，其中硅烷處理、Zr-Ti系無鉻鈍化還處于逐步成熟階段。特別是Zr-Ti系無鉻鈍化工藝由于其轉化膜呈略白色及淺藍色，不能通過目測來直觀的檢測鈍化膜的質(zhì)量，在生產(chǎn)的過程控制難度較大，曾經(jīng)有部分企業(yè)在無鉻鈍化工藝上經(jīng)歷了挫折。在此，本文將Zr-Ti系無鉻鈍化工藝在我公司的應用經(jīng)驗與大家分享。江蘇通用氟鋯酸鉀性價比氟鋯酸鉀對人體是否有危害？</p><div

Morueau和Vauquelin兩人都證實M.H.Klaproth的分析是正確的，該元素拉丁名為Zirconium，符號認為Zr，中國譯成鋯，1808年，英國的H.Davy利用電流分解鋯的化合物，沒有成功，1824年瑞典的J.J.Berzelius首先用鉀還原K2ZrF6時制得金屬鋯，但不夠純，反應式為：K2ZrF6+4K=Zr+6KF，該反應也可用Na作還原劑，直到1914年，荷蘭一家金屬白熱電燈制造廠的兩位研究人員Lely和Ham

鋯是一種活潑金屬，在25℃時的標準電極電位為-1.53v，比鐵（-0.036v）,銅（0.336v）的標準電極電位更負。根據(jù)化學熱力學，鋯在腐蝕環(huán)境中比鐵、銅更不穩(wěn)定，即更易遭受腐蝕。但鋯與氧有很高的親合力，當鋯暴露在含氧環(huán)境中（如在室溫空氣或水中），表面上會生成附著力很強的致密氧化膜。在300℃以下，這層膜能自愈以保護基體金屬免受化學或機械破壞。因此，鋯能耐很多化學物質(zhì)，包括各種無機酸（如鹽酸、***、硝酸等）、堿，大部分有機酸（如醋酸、甲酸等），各種鹽溶液及熔融堿的腐蝕。鋯**重要的耐蝕特性之一是在所有濃度、溫度直至高于沸點的鹽酸中均有優(yōu)異的耐蝕性江蘇正規(guī)氟鋯酸鉀來電咨詢</p><p
