| Highly
Effective Degreaser
(Product No.: ABP-R)
The product is widely used in the surface decontamination
treatment of aluminum materials. It can fast remove
the oil contamination and spontaneous oxide membrane
on the aluminum material surface, and it is especially
suitable for the degreasing treatment of aluminum anode
oxidation and coating pretreatment.
1. Chemical Characteristic:
Acidic, yellow liquid, lightly corrosive.
2. Technical Parameters:
2.1Operation Index Parameters:
Operation index: 80-120
Temperature: normal temperature
Treatment time: 3-8min (depending on the oil contamination
degree of workpiece)
2.2 Trough Setting Parameters:
ABP-R: 5-8%
Remaining Quantity: Tap water
3. Maintenance of Trough Solution:
3.1 The trough solution should be controlled and replenished
according to the technical parameter index. For each
production batch, the trough solution should be adjusted
at least twice according to the test result to ensure
the decontamination effect.
3.2 For newly prepared trough solution, the treatment
time can be shortened accordingly. If the trough solution
has been used for a long time, or the treatment quantity
is large, the bottom solution can be discharged, and
the trough solution should be adjusted to meet the criterion
of the above technical parameters by replenishing components.
4. Process and Consumption Index:
4.1 Process:
Anode oxidation: degreasing — water-washing —
water washing — acid or alkali corrosion —
water-washing — water-washing — anode oxidation
Coating pretreatment: degreasing — water-washing
— water washing — (alkali corrosion —
water-washing — water-washing — neutralization
— water-washing) — chromate treatment —
water-washing — water-washing — dry (the
process in the parentheses can be omitted)
4.2 Consumption Index
Consumption index is determined according to the thickness
and surface oil contamination degree of aluminum workpiece.
Generally, when the average thickness of aluminum materials
is more than 1mm, the consumption is 3-4kg (it is also
the consumption parameter for one ton of aluminum materials
with an exterior surface of 430m2.
5. Note:
The highly effective degreaser is prepared by combining
surface activating reagent (from foreign country) with
mineral acid compound (from foreign country). As its
decontamination effect is brilliant, it has been employed
in tens of manufactories in the country. The product
has been improved to meets the high criterion of coating
pretreatment. To keep a sound operation, the following
criteria should be met:
5.1 While preparing the trough, tap water or deionized
water should be used. If the groundwater is used instead,
take care that the contents of Mg2+ and Ca2+ in the
groundwater should not be too high.
5.2 If the product is used in the coating pretreatment,
the workpiece should be treated by secondary water-washing
before chromate treatment. Users without secondary water-washing
device can spray water to wash the workpiece in the
same water-washing trough.
5.3 As the components contain surface activating reagent,
foams (especially for the newly prepared trough solution)
will appear during the process. Immersion in the water
trough for one minute can reduce the foams.
5.4 If the oil contamination on the aluminum workpiece
surface is too heavy to remove, the immersion time can
be lengthened.
6. Environment Protection
Generally, like other general waste water, the sewage
can be treated with environment protection facilities.
7. Analysis Method:
Determination of operation points: Add 20ml of operation
trough solution to a 250ml conical flask, and add 50ml
of water, then add 2-3 drops of 1% phenolphthalein as
indicator, and then titrate the solution with 0.1N NaOH
standard solution till the end point (pink). Record
the consumption volume (ml) of NaOH standard solution.
Calculation: operation points of the trough solution=10NNaOHVNaOH
