1.彩涂板的部分力学性能(如屈服强度、伸长率)和部分涂层性能(如铅笔硬度、T弯值、冲击力)通常会随储存时间的增加而变化,从而对加工成形产生影响,对此应给予足够的重视2.零件的形状复杂、变形程度较大时,应采用多道次成形。如果一次成形,可能会因变形量过大破坏涂层的附着力3.加工时产生的切口断面易发生腐蚀,因此应采取必要的防护措施,如涂防护涂料、嵌封条等4.加工时应尽量减少切断面的毛刺,防止毛刺划伤表面,应保持所有与涂层接触的表面干净整洁,及时清理加工时产生的切屑和金属颗粒,防止异物损坏涂层表面5.加工时如发现涂层表面破损应及时采用专用修补涂料进行修补,防止破损处发生腐蚀1.SomemechanicspropertiesofColorPlate(yieldstrengthandextensibility)andpartcoatingfeatures(hardness,Tbendvalue,impactforce)willbringdifferenteffectsinprocessingwiththechangesofincreasingstoragetime.Theusershouldpayanadequateattentiononthisphenomenon.2.Theproductsshouldbetakenshapeforseveraltimeswhentheshapeofcomponentsiscomplex.Becauseitmaydamagetheadhesionofcoatingsifthesteelshapedinasingleprocess.3.Thecutsectionislikelytohavecorrosion.Thus,theusershouldtakenecessaryprotectivemeasuressuchasprotectivecoatingsandsealingtoavoidcorrosion.4.Theusershouldtokeeptheenvironmentdryandtidyandtopreventglitchesscratchthesurfaceofcoatings.5.Theusershouldtorepairthedamagedcoatingsurfaceassoonaspossible,asthebreakageislikelytohavecorrosion.
