彩涂板是冶金和化工相結(jié)合的表面處理工程的重要產(chǎn)品，彩涂板作為表面技術(shù)處理產(chǎn)品，其產(chǎn)品質(zhì)量不僅僅局限于產(chǎn)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(chǎn)品的涂層表面質(zhì)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.

2）薄板產(chǎn)品在捆扎時(shí)的扎痕。

3）倒卷時(shí)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(diǎn)：兩側(cè)沾有涂料，經(jīng)烘干，出現(xiàn)氣泡

發(fā)生原因：原材有毛刺沾有涂料多，兩邊出現(xiàn)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(diǎn)

特點(diǎn)：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(fā)生原因：

1）涂料中混入其它種類(lèi)或其它公司的涂料。

2）涂料中有異物混入引起。

3)前處理過(guò)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(diǎn)：已干燥的表面涂層象橘子皮一樣粗糙，不均勻

發(fā)生原因：

1）濕膜過(guò)厚。

2）涂料的黏度較高時(shí)。

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(diǎn)：丁酮擦拭有點(diǎn)狀掉漆

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(diǎn)：漆膜沖擊后，經(jīng)膠帶粘后部分或全部掉漆

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

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.
