PAPE Corrosion Inhibitor, PAPE Antiscalant

Molecular Components: C2H8O8P2.(C2H4O)n

Structural Formula:

Polyhydric Alcohol Phosphate Ester


Esterification during manufacturing introduces several Polyethylene Glycol groups. This certainly increases its own corrosion inhibition functionality to Ca2+ scale. Its have an effect on Ba2+ and also Sr2+ can also be excellent.

PAPE corrosion inhibitor provides excellent compatibility together with polycarboxylates and then organophosphonates. Its power to control Zn2+ is definitely featured. Therefore, PAPE antiscalant can certainly be manufactured to dispersive antiscalant and inhibitor. Quaternary ammoniums such as DDBAC may also be developed with PAPE and without complex produces just like takes place among Quaternary and polycarboxylates/organophosphonates.

As being the corrosion inhibitor and antiscalant, PAPE effect is special for the cooling water which contains oil. And that is common in a refinery. PAPE antiscalant is additionally applied in oilfield (as being a substitute of Nalco Visco 953), fertilizer grow, air conditioning system, and also a copper heat exchanger. PAPE corrosion inhibitor will probably break down during three or four days and nights after release and also has absolutely no polluting of the environment.

When PAPE corrosion inhibitor used by itself, 5-10 mg/L is commonly added for the purpose of anti-scaling. The more amount to use is obtained for better corrosion inhibition. PAPE is able to reach even 150 mg/L inside a closed circulating system. pH 7.0-8.5 is advisable.

Packing and Storage:

200L plastic-type material drum, IBC(1000L), customers’ needs. Storage for 10 months inside a shady space and dry area.

PAPE antiscalant is one of the fine chemical products. To ensure its performance, moisture should be avoided. Because some water treatment agents react quickly if they encounter moisture. So be sure to store it in a dry area. This is the most basic requirement.

Second, different water treatment agents are placed in different places. Also some of the water treatment agents put together to produce a chemical reaction. And it is easy to make mistakes and cause a lot of trouble.

Since the stock of PAPE should be kept dry, keep away from water sources. The last point is that since the drug contains organic substances, keep PAPE corrosion inhibitor away from open flames and avoid reactions.

Basic safety Protection:

Acidity, avoid contact eyes as well as skin area. Once contacted, clean by using water.
