style="text-indent:25px">高錳酸鉀氧化容量法在硫酸磷酸混合酸介質(zhì)中，用高錳酸鉀氧化釩以亞硝酸鈉還原，用硫酸亞鐵銨標準溶液滴定測量釩的含量。測定鍍鋅管中含鉻量的方法主要有過硫酸銨銀鹽容量法、二苯卡巴阱比色法、二甲苯橙法、電位或目視滴定法、高錳酸鉀滴定法、火焰原子吸收光譜法等。一般低合金鋼常采用二苯卡巴阱比色法，高合金鋼常采用容量法。測量鍍鋅管中錳含世的方法有亞砷酸鈉-亞硝酸鈉容14法(過硫酸鐵容量法)、磷酸-三價錳容量法、過硫酸銨比色法、過碘酸鹽比色法、高氣酸法、火焰原子吸收光譜法、電位滴定法、電流滴定法、高錳酸鉀滴定法等。其中容量法是測定鋼中含錳量較常用方法。</p><p style="text-indent:25px">鍍鋅管酸洗鈍化的制作知識：酸洗是把載體用6mol/L鹽酸浸煮2h或濃鹽酸加熱浸煮30min，過濾，用水洗至中性，烘干。酸洗可除去表面上的鐵、鋁、鈣、鎂等雜質(zhì)，但不能除去硅醇基。酸洗載體適宜于分析酸性樣品。對精密無縫鍍鋅管表面進行除油、除銹，以便進行下道工序處理做準備。在生產(chǎn)過程中，酸洗過程就是為了去除表面氧化皮，后經(jīng)過潤滑處理（碳素鋼-磷皂化，鍍鋅-牛油石灰，銅鋁管-涂油），用老工藝-鍍銅），再進行拔制深加工。鍍鋅管如果不酸洗、表面可能有氧化物和油污，磷化液核能無法將它們除去，磷化質(zhì)量會降低。鍍鋅管對壓制材的質(zhì)量要求如硬度、光澤等。</p><div
