纸杯机表面处理工艺:正规工艺 vs 偷工减料对比

 

Surface Treatment for Paper Cup Machines: Standard vs. Cutting Corners

 

1. 发黑 / Blackening

 
正规工艺
 
钢铁件经化学氧化形成均匀黑色保护膜,后续做浸油封闭,防锈、哑光、不反光,多用于内部轴类、齿轮。
 
Standard Process
 
Uniform black oxide film formed via chemical oxidation, sealed with oil for anti-rust, matte finish. Used for internal shafts and gears.

2. 电镀 / Electroplating

 
正规工艺
 
通过电解镀上锌 / 镍 / 铬等,镀层厚度均匀达标,镀前除油除锈,镀后钝化封闭,防锈、耐磨、外观光亮。
 
Standard Process
 
Uniform coating (Zn/Ni/Cr) via electrolysis, proper pre-treatment & passivation, good anti-rust & wear resistance.

3. 喷塑(静电粉末喷涂)/ Powder Coating

 
正规工艺
 
钣金先喷砂 / 磷化处理,静电喷粉后高温固化,涂层厚实均匀、硬度高、耐刮、不掉漆。
 
Standard Process
 
Sandblasting/phosphating pretreatment, electrostatic spraying + high-temperature curing, tough & durable coating.

4. 喷漆 / Painting

 
正规工艺
 
底漆 + 面漆 + 烘干,漆膜饱满、附着力强、防锈美观。
 
Standard Process
 
Primer + topcoat + baking, strong adhesion & good anti-rust performance.
