Chemical Polishing Comparison
Comparison between Non Fume Mirror-Like Chemical Polishing and conventional tri-acid polishing methods for Aluminum alloy
WORLDCLEAN SE-NSP-35L
|
Conventional tri-acid polishing
|
|
Consumption
|
After polishing, Aluminum profiles are able to stay in air long time for chemical compound dripping. Therefore, consumption of chemical saves more than 70% comparing to conventional tri-acid polishing.
|
After polishing, only having 20 seconds to stay in air for chemical compound dripping. (Not easy for automatic line operation.) Consumption of chemical is very high.
|
Efficiency
|
Larger racking area. Able to rack multiple rows. No rejects. Efficiency is at least as two times as conventional tri-acid polishing.
|
Smaller racking area. Only single or double rows every time. And many rejects. Efficiency is very low.
|
Brightness
|
High brightness and very stable. Different batches and racks can maintain the same brightness.
|
Due to fast volatility of nitric acid and phosphoric acid/sulfuric acid must control manually, brightness varies a lot. Therefore, continuously monitored by human and instrument is necessary.
|
Management
|
Management is easy. Just adding original solution. NO adjustment required. Brightness is stable. Easy to compare finished product with template.
|
Manually add three different acids. Easy to cause unbalanced concentration. Must keep monitoring concentration changes of three acids. Multiple adding nitric acids are necessary for every shift. Brightness changes and unstable. Difficult to compare finished product with template.
|
Service
|
Ingredient is fixed. Almost no adjustment is required. If some rare condition happens, consulting by phone to adjust is possible. Service and support is quick and fast.
|
Concentration of three acids changes all the time. Adjustment is always required and need to be done by buyer himself.
