Stainless steel acid pickling
Acid pickling deactivation paste
Deactivated paste
QS-001 stainless steel acid pickling deactivation paste stainless steel acid pickling deactivation paste (QS-001) Two steps unites the performance to be outstanding
Performance characteristic:
the oxide skin which 1.1 this use in the stainless steel stock weld joint and the superficial acid pickling deactivation, after the elimination welding, the high temperature processing process , produces, enables it silvery bright to have the light, after and causes processing the surface forms one take the chromium as main material oxygen the membrane, will not produce two oxygen to eclipse again, serves the deactivated purpose, will thus enhance the stainless steel product the superficial anticorrosion quality, extension useful life of equipment. The stain removal and the deactivated effect surpasses the overseas similar products (AVESTA) to achieve the international advanced level.
1.2 this carry on the acid pickling and the deactivated synchronization, one step completed, changed the traditional acid pickling and the deactivated craft, operated to be simple, the construction was convenient, the cost was inexpensive.
1.3 use this does not need the special equipment and the location, does not need the heater and the power source, does not need the operation worker who technical ripe practices, the labor saving, time-saving, the energy conservation.
1.4 this are one kind of stable medicinal extract, it does not decompose, does not precipitate, the transportation convenience and may the long-term preservation, along with use along with to take, facilitates to extremely.
applicable scope:
widely uses in stainless steel equipment, pressure and so on chemical industry, drugs manufacture, papermaking, food, aviation, nuclear industry, building the vessel, the project component's surface treatment.
technical specification:
project Unit Target
outward appearance Crystalline transparent paste body
free acidity Spot 8.5X102
total acidity Spot 1.50X102
chloride ion content Mg/kg 25-100
deactivation film thickness A0 150-600
from corrosion potential (EC) MV/SCE +202
hole corrosion potential (Eb) MV/SEB +492
microscope examination The deactivated membrane does not have the rusty stain, the non eclipse
examination method Uses the international general stainless steel blue spot to examine the fluid examination
application method:
4.1 use the plastic good or the stainless steel rod is even this agitation.
4.2 smudge the thickness 1-3 millimeters coating.
4.3 guarantee enough reaction time (approximately 20 minutes). The time, the temperature and the acid pickling effect are proportional.
0℃ following construction suitable extension of time.
4.4 use the stainless steel wire brush, the plastic to brush and so on non-carbon steel tool, eliminates the superficial loose residue.
4.5 strip with water is processed cleanly the surface.
the 4.6 like stainless steel surfaces have the greasy dirt, may use resolver eliminations and so on acetone.
