熱鍍鋅抗腐蝕能力遠(yuǎn)遠(yuǎn)高于冷鍍鋅（又稱電鍍鋅）。熱鍍鋅在幾年里都不會生銹，冷鍍鋅在三個月內(nèi)就會生銹。<br /> 冷鍍鋅工藝用于保護(hù)金屬防止腐蝕，為此利用了鋅填料的涂料，在利用任何一種涂敷的方法將其涂在被保護(hù)表面，干燥之后形成鋅填料涂層，在干燥涂層中具有含量的鋅（達(dá)到95%）。鋼鐵在冷卻的條件下在表面鍍鋅，而熱鍍鋅是鋼管在熱浸的條件下對表面鍍鋅，它的附著力很強(qiáng)，不容易脫落，熱鍍鋅管雖然也出現(xiàn)銹蝕的現(xiàn)象，但在很長的周期可以滿足技術(shù)、衛(wèi)生要求。當(dāng)然在使用時還是得根據(jù)實際情況進(jìn)行購買，有不懂的地方可以咨詢濟(jì)寧冠翔物資。我們將用自己多年的經(jīng)驗為您解決您的問題。歡迎致電咨詢！

金屬材料抵抗硬的物體壓陷表面的能力，稱為硬度。根據(jù)試驗方法和適用范圍不同，硬度又可分為布氏硬度、洛氏硬度、維氏硬度、肖氏硬度、顯微硬度和高溫硬度等。對于管材一般常用的有布氏、洛氏、維氏硬度三種。 </p> <p> A、布氏硬度（HB） </p> <p> 用一定直徑的鋼球或硬質(zhì)合金球，以規(guī)定的試驗力（F）壓入式樣表面，經(jīng)規(guī)定保持時間后卸除試驗力，測量試樣表面的壓痕直徑（L）。布氏硬度值是以試驗力除以壓痕球形表面積所得的商。以HBS（鋼球）表示，單位為N/mm2（MPa）。 </p> <p> 其計算公式為： </p> <p> 式中：F--壓入金屬試樣表面的試驗力，N； D--試驗用鋼球直徑，mm； d--壓痕平均直徑，mm。 </p> <p> 測定布氏硬度較準(zhǔn)確可靠，但一般HBS只適用于450N/mm2（MPa）以下的金屬材料，對于較硬的鋼或較薄的板材不適用。在鋼管標(biāo)準(zhǔn)中，布氏硬度用途較廣，往往以壓痕直徑d來表示該材料的硬度，既直觀，又方便。 </p> <p> 舉例：120HBS10/1000/30：表示用直徑10mm鋼球在1000Kgf（9.807KN）試驗力作用下，保持30s（秒）測得的布氏硬度值為120N/ mm2（MPa）。 </p> <p> <br /> 螺旋管也稱螺旋鋼管或螺旋焊管。蚌埠無縫管</p><p
