彩涂板是冶金和化工相結合的表面處理工程的重要產品，彩涂板作為表面技術處理產品，其產品質量不僅僅局限于產品的理化性能（膜厚、光澤、柔韌性、耐反向沖擊性、耐溶劑性、耐腐蝕性、耐候性等），還包括彩涂板產品的涂層表面質量。 Color coating is an important product of metallurgical and chemical surface treatment engineering, color coating as a surface technology products, the product quality is not limited to the physical and chemical performance of the product (film thickness, luster, flexibility, reverse impact resistance, solvent resistance, corrosion resistance, weather resistance, etc.), also includes the coating surface quality of color coating products. 1. 彎曲性不良 特點：鋼材彎曲180度試驗時，加工部位的涂層發生龜裂及涂層剝離 發生原因： 1）、前處理的掌握量過多。 2）、涂層厚度過厚。 3）、過度烘烤。 4）、下涂涂料同上涂涂料的制造廠家不同，或稀料的使用不當。 1.Poor curvature Features: When the steel bending 180 degrees test, the coating of the processing site crack and coating stripping Causes: 1)Too much mastery of pre-processing. 2) The coating thickness is too thick. 3) Excessive baking. 4) The lower coating is different from the manufacturer of the upper paint, or the improper use of dilute materials. 2.硬度不良 特點：用制圖鉛筆用力在涂層表面劃一道，擦去后表面留下一道劃痕 發生原因： 1）爐溫低，涂層固化不充分。 2）加熱條件不適當 3）涂層厚度比規定的厚 2. Poor hardness Features: Use a drawing pencil to scratch the coating surface, wipe off the rear surface and leave a scratch Causes: 1) The furnace temperature is low, and the coating curing is not sufficient. 2) Improper heating conditions 3) The coating thickness is thicker than that specified 3. 凸點 特點：由于鋼帶受到外部的沖擊，板表面出現突出或凹陷，有的有一定的間距，有的沒有 發生原因： 1）涂裝時輥上有異物混入。 2）薄板產品在捆扎時的扎痕。 3）倒卷時受到外部沖擊。 3. The convex point Features: because of the steel belt by the external impact, the plate surface appears prominent or depression, some have a certain spacing, some do not Causes: 1)There are foreign matter on the roller during coating. 2) Tie marks of sheet products during binding. 3) Get external impact when inverted. 4. 邊部氣泡 特點：兩側沾有涂料，經烘干，出現氣泡 發生原因：原材有毛刺沾有涂料多，兩邊出現縫隙 4.The convex point Features: because of the steel belt by the external impact, the plate surface appears prominent or depression, some have a certain spacing, some do not Causes: 1) There are foreign matter on the roller during coating. 2) Tie marks of thin plate products during binding. 3) Get external impact when inverted. 4)Side air bubbles Features: both sides are stained with coating, after drying, air bubbles appear Cause of occurrence: raw material has burr stained has paint much, both sides appear gap 5.麻點 特點：從外部混入的異物或灰塵在涂裝后部分或全部表面有米粒樣的突出發生原因： 1）涂料中混入其它種類或其它公司的涂料。 2）涂料中有異物混入引起。 3)前處理過程中水洗不良。 5. The hemp point Features: Foreign body or dust mixed from the outside highlights on some or all of the surface after coating Causes: 1)Mix aint with other types or other company coatings. 2) Mixed substances caused by foreign bodies in the paint. 3) Poor water washing during pretreatment. 6.橘皮 特點：已干燥的表面涂層象橘子皮一樣粗糙，不均勻 發生原因： 1）濕膜過厚。 2）涂料的黏度較高時。 6. Orange peel Features: The dried surface coating is as rough and uneven as the orange peel Causes: 1)The wet film is too thick. 2) When the viscosity of the coating is high. 7.耐溶劑性能差 特點：丁酮擦拭有點狀掉漆 發生原因： 1）烘烤溫度沒有達到要求 2）涂料的固化有問題 3）前處理清洗不干凈 7. Poor solvent resistance performance Features: Butanone wipe a bit off the paint Causes: 1) The baking temperature did not meet the requirements 2) The curing of the coating is problematic 3) The cleaning is not clean 8.沖擊不合格 特點：漆膜沖擊后，經膠帶粘后部分或全部掉漆 發生原因： 1）前處理不佳 2）檢查面漆固化溫度是否合理 8.Inqualified impact Features: paint film impact, part or all of the paint Causes: 1)Poor pre-processing 2) Check whether the curing temperature of the surface paint is reasonable 9.縮孔 特點：漆膜不平整，局部露底 發生原因： 1) 鋼帶表面不潔凈 2)底漆冷卻水不潔凈 3)涂料粘度沒達到上機要求 9. Shaft hole Features: the paint film is uneven, and the local dew base Causes: 1)The steel strip surface is not clean 2) The primer cooling water is unclean 3) The coating viscosity does not meet the upper machine requirements 10.漏涂 特點：面漆未涂上 發生原因： 1）邊部面漆未涂上，基板板型不好或涂輥與大背輥間壓力不足。 2）板面中間面漆未涂上，底漆冷卻后板面有水或其它異物。 10.Leakage Features: Finish is not painted Causes: 1）The side finish paint is not painted, the substrate plate type is not good or the pressure between the coated roller and the large back roller is insufficient. 2）The middle finish of the plate is not coated, and there is water or other foreign matter after cooling the primer. 11.色差 特點：同標準板的顏色出現差異 發生原因： 1）
