The difference between HEDP solids and liquids is mainly reflected in their physical properties and uses. HEDP( 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid) has a colorless and transparent liquid state and a white crystal solid state. It has good chemical and thermal stability and is widely used as a chemical substance in industrial and agricultural fields.

Differences between HEDP solids and liquids

Different physical properties

From a physical property perspective, HEDP solids exist in the form of white crystalline particles. It has a relatively high melting and boiling point and generally requires heating to melt or melt into a liquid.
HEDP liquid exists in the form of a solution, and the concentration and solubility of HEDP liquid can be adjusted according to actual needs, with good adjustability and adaptability.

Different levels of phosphite

The content of phosphite in solid and liquid HEDP is different, and based on PO33-, solid HEDP is four times higher than that in liquid.

Different phosphoric acid content

HEDP solid phosphoric acid, calculated as PO43-, with a content less than 0.5%, and HEDP liquid content less than 0.8%

Different uses

HEDP liquid has different ratios and concentrations, and its effects vary. It can be used not only as a scale inhibitor, but also as a corrosion inhibitor. When the concentration exceeds 1000 milliliters per liter, it can be used as a cleaning agent.
HEDP solid is a high-purity product mainly used in cold winter areas, especially suitable for cleaning agents and daily chemical additives in the electronics industry.

Different storage methods

HEDP solids are generally packaged in plastic woven bags lined with polyethylene bags, with a net weight of 25 kilograms or 50 kilograms per bag, which can be customized and more convenient for transportation compared to liquids.
HEDP liquids are generally packaged in plastic drums, with 25kg, 200kg, 250kg or ton drums. HEDP liquids require certain packaging and storage conditions to prevent evaporation, leakage, or spillage. Liquid HEDP generally needs to be stored in sealed containers and careful to avoid mixing with other chemicals.
Let's take a look at a table that reflects the differences between HEDP solids and liquids

In summary, there are some significant differences between HEDP solids and liquids. From a physical property perspective, solid HEDP exists in crystalline form, while liquid HEDP exists in solution form. Due to different states of matter, there are also differences in storage and transportation between the two. These differences give HEDP solids and liquids their respective advantages and applicability in practical applications, requiring selection and use based on specific needs.
