Shandong Kairui Chemistry Co., Ltd.  is a professional hedp2na manufacturer, the company produces 8 series of hedp/pbtc/atmp more than 100 products to meet the needs of different customers.

HEDP (1-hydroxyethylphosphonic acid) and HEDP•Na2 (1,2-dihydroxyethylidenebisphosphonic acid) are both hydroxyethylphosphonic acid compounds, and there are some differences between tha:

Chaical structure: HEDP is an abbreviation for hydroxyethylphosphonic acid with the chaical formula C2H8O7P2. HEDP-2 is an abbreviation for 1,2-dihydroxyethylidene diphosphonic acid with the chaical formula C2H6O7P2Na2.

Functional properties: HEDP and HEDP-2 are compounds with chelating effect, with good corrosion and scale inhibition performance, commonly used in water treatment, metal corrosion inhibition and other fields.

Application scope: HEDP is widely used in industrial water treatment, oil extraction, paint, textile and other fields. HEDP-2 contains two hydroxyethyl groups in its molecule, which has h3er complexing performance and industrial application value.

Appearance: HEDP is often white crystalline powder, while HEDP-2 is usually colorless or light yellow crystalline powder.

It should be noted that the above are only some basic differences between HEDP and HEDP-2, and the specific properties and applications need to refer to the relevant chaical literature and data. In actual use, please select the appropriate compound according to the specific needs and circumstances.

Sodium polyacrylate dispersant is an important polymer compound with a wide range of uses:
I. Uses in the field of coatings and paints
Pigment dispersion

- Polyacrylic Acid Sodium Salt Solid can be adsorbed on the surface of pigment particles. Due to its molecular chain with a large number of carboxyl and other polar groups, these groups can prevent the pigment particles from agglomerating in the coating system through electrostatic repulsion and spatial site resistance effect. For example, in water-based coatings, the dispersion effect is very good for inorganic pigments such as titanium dioxide. When the pigment particles are evenly dispersed, the color of the paint is more uniform and the covering power can be effectively improved. - It also improves the fluidity of the pigment, which makes the paint easier to brush or spray during the construction process and reduces the probability of defects such as sagging and orange peel. 2.
Improve paint stability

In the pulp bleaching process, EDTMPS is mainly used as a chelating agent to raove or control metal ions in the pulp, especially transition metal ions such as iron and manganese. These metal ions catalyze the decomposition of bleaching agents (e.g. hydrogen peroxide), which reduces bleaching efficiency and may lead to yellowing of the paper.
