/> </p> <p> 1、瀝青漆涂層，噴漆前對(duì)沖壓拉伸件進(jìn)行預(yù)熱可以提高瀝青漆的附著力，加速干燥。 </p> <p> <br /> </p> <p> 2、水泥砂漿內(nèi)襯加特殊涂層，可以提高沖壓拉伸件內(nèi)襯的抗腐蝕能力。 </p> <p> <br /> </p> <p> 3、環(huán)氧煤瀝青涂層是一種雙組分涂層，該涂層具有較高的附著力和非常光滑的表面。 </p> <p> <br /> </p> <p> 4、環(huán)氧陶瓷內(nèi)襯由于制造工藝難度大，成本高，所以在使用上有一定的局限性，具有很高的附著力和光潔度，是一種沖壓件防腐蝕涂層。 </p> <p> <br /> </p> <p> 5、鋁酸鹽水泥涂層或***鹽水泥涂層，這兩種特殊水泥涂層均適用于沖壓拉伸件的內(nèi)防腐，提高抵抗侵蝕的能力。 </p> <p> <br /> </p> <p> 6、聚氨酯涂層是一種為適應(yīng)環(huán)保需求而研制開發(fā)的一種新型綠色特殊涂層，有良好的耐磨和耐腐蝕性。 </p> <p> <br /> </p><div style="width:100%;text-align:
