HEDP corrosion inhibitor, HEDP antiscalant - IRO Water Treatment
HEDP corrosion inhibitor, HEDP antiscalant 2019-03-19T08:00:57+00:00

HEDP corrosion inhibitor, HEDP antiscalant

HEDP corrosion inhibitor is generally manufactured from the reaction of phosphorus trichloride (PCl3) and then Glacious Acetic Acid (CH3COOH) with the tertiary amine. In addition, many factories also have a different continual procedure in order to synthesize HEDP antiscalant via Phosphorous Trichloride (PCl3) and Acetyl chloride (CH3COCl).

HEDP corrosion inhibitor

Properties:

HEDP is a fantastic oxidation inhibitor as well as antiscalant. HEDP antiscalant also can dissolve the oxidized components upon most of these metals’ surfaces. It exhibits fantastic scale and corrosion inhibition good results lower than temp 250℃.

With high pH value and 250℃, HEDP corrosion inhibitor displays great chemical reliability. It is hard for being broke down through usual light and also heat circumstances. In fact, HEDP acid ability to tolerate acid, alkali and then chlorine oxidation is better than a lot of the some other organophosphonates.

HEDP also can react along with steel ions within the water program to make a hexa-element sequesting complex. HEDP corrosion inhibitor could chelate along with barium, Pb, ferrum, Zn, Cu ion and also calcium ions. For that reason, HEDP corrosion inhibitor has got great antiscale and noticeable threshold effects. The actual oxidate on these steel surfaces will likely be resolved just by HEDP antiscalant. Synergy will probably be reached the moment HEDP was made with many other water treatment agents, generally polycarboxylic acid.

Aside from liquid, HEDP solid is available as crystal powder with regard to cold zones, specifically in winter season. Due to HEDP solid is normally high purity, you can use it like a sequesting chemical within electronic areas and also as additives in daily agents.

Application:

HEDP antiscalant is commonly used as scale and corrosion inhibition during circulating cool water technique, petrol industry and also low-pressure central heating boilers in industries. HEDP corrosion inhibitor is usually frequently used electric power station, oil and gas industries, chemical factories, a metallurgic factory for cooling water technique and boilers just as scale inhibitor along with the preferred amount to use 1-10mg/L (antiscalant) and also 10-50mg/L (corrosion inhibitor).

Within the daily chemical market, HEDP corrosion inhibitor is commonly used as steel and nonmetal detergent. The amount to use is commonly 1,000-2,000 mg/L. Additionally, it is a peroxide stabilizer and dye-fixing chemical in the dyeing business.

Ordinarily, HEDP chemicals are utilized with the polycarboxylic acid.

Package and Storage:

Liquid: 200L plastic drum, IBC (1000L), customers’ needs.

Solid: 25kg/bag, customers’ needs.

Storage for ten months within a shady place and dry area.

HEDP antiscalant is a fine chemical product. 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, HEDP corrosion inhibitor products 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 HEDP chemicals should be kept dry, keep away from water sources. The last point is that since the drug contains organic substances, keep away from open flames and avoid reactions.

Basic safety Protection:

Acidity, avoid contact with eyes and skin area. Once got into contact with it. Please clean with water.
