鋁型材表面油痕的特性反映:
The characteristics of oil marks on the surface of aluminum profiles reflect:
鋁型材時效前油漬不擦干凈在時效后在鋁材表面產(chǎn)生水印,氧化后呈暗斑且有高度。
The oil stains on the aluminum profile before aging are not wiped clean. After aging, watermarks are generated on the surface of the aluminum profile, and after oxidation, they appear as dark spots and have a height.
鋁型材表面油痕產(chǎn)生原因:
Reasons for oil marks on the surface of aluminum profiles:
1、成品鋸鋸切油漬留在鋁型材兩頭,搬(抬)料時手套不干凈甚至粘有石墨灰;
1. The oil stains left on both ends of the aluminum profile during the sawing and cutting of the finished product, and the gloves were not clean or even adhered with graphite dust when moving (lifting) the material;
2、鋁型材拉伸時手套臟拿料過長,鋸切未去掉;
2. When stretching aluminum profiles, the gloves are dirty and the material is taken too long, and the sawing is not removed;
3、中間理料時手套臟,留“印記”;
3. Gloves are dirty and leave "marks" during intermediate material handling;
4、擠壓設(shè)備工具漏滴油跡(行車,吊裝帶)。
4. The tools of the extrusion equipment leak oil stains (traveling crane, lifting belt).

鋁型材表面油痕去除辦法:
Method for removing oil marks on the surface of aluminum profiles:
1、鋁材生產(chǎn)過程中理料,抬搬料時手套要干凈,有油跡要及時擦掉;
1. During the production process of aluminum materials, gloves should be clean when lifting and transporting materials, and any oil stains should be promptly wiped off;
2、拉伸鋁材時拿料要適當(dāng);
2. When stretching aluminum materials, take appropriate materials;
3、理料,抬搬料時的手套和拉伸拿料,加棒時的手套要分開;
3. Material handling, gloves for lifting and carrying materials, and gloves for stretching and taking materials, and gloves for adding rods should be separated;
4、設(shè)備,工具注意漏油,墊紙墊條吊帶等要干凈。
4. Attention shall be paid to oil leakage of equipment and tools, and the paper pad, strip sling, etc. shall be clean.
鋁型材表面水印的特性反映:
The characteristics of the watermark on the surface of aluminum profiles reflect:
鋁型材表面出現(xiàn)銀灰色濕狀印斑,鋁合金型材隨氧化堿洗的強度增加而減淡或消失。
Silver gray wet stains appear on the surface of aluminum profiles, and aluminum alloy profiles fade or disappear as the strength of oxidation and alkali washing increases.
鋁型材表面水印產(chǎn)生原因:
Reasons for generating watermarks on the surface of aluminum profiles:
鋁型材表面局部沾水淋雨,經(jīng)型材表面淬火氧化層細(xì)微小孔滲入鋁基體,形成三羥鋁石,隨水份停留時間長短而現(xiàn)明淡,如果水中有雜質(zhì)(鹽,亞硝酸等)會產(chǎn)生腐蝕斑。
Local parts of the surface of aluminum profiles are soaked in water and rain. After being quenched on the surface of the profile, the oxide layer penetrates into the aluminum matrix through fine pores, forming trihydroxyaluminite, which gradually fades with the length of the water retention time. If there are impurities (salt, nitric acid, etc.) in the water, corrosion spots will occur.
鋁型材表面水印去除辦法:
Method for removing watermarks on the surface of aluminum profiles:
沾水的鋁型材要馬上擦干,在時效前需要擦干,條件充許的話適當(dāng)增加堿冼時間和氧化膜厚度。
Aluminum profiles that have been wetted with water should be wiped dry immediately and before aging. If conditions permit, the alkali washing time and oxide film thickness should be appropriately increased.
