Chelating agents are compounds that can form stable complexes with metal ions. The composition of chelating agents is usually organic compounds, and common chelating agents include organic acids, organic amines, and organic sulfides. Organic acids are one of the most common chelating agent components, and commonly used organic acids include acetic acid, oxalic acid, acetic…
Water reducing agent is a chemical substance added to concrete or mortar, which can reduce its cement content, improve its fluidity and workability. The process of action of water reducing agents is as follows: 1. Dispersion: The active ingredients in the water reducer can interact with the surface of the cement particles, change their Surface…

The main components of heavy metal chelating agents are usually one or more compounds that can form stable complexes with heavy metal ions. Common components of heavy metal chelating agents include organic acids, organic amines, and phosphine compounds. Organic acids are one of the common components in heavy metal chelating agents. They usually contain acidic…

Differentians are an additive widely used in the particle system. The main role is to disperse solid particles evenly and prevent it from re -aggregating. The mechanism of the scattered agent can be explained in the following aspects: Adsorption effect: The molecule of the active compound (such as the surfactant) in the dispersant will be…
The water reducing agent is a additive commonly used in concrete and mortar. The mechanism of decentralization is as follows: Surface active agent: Water reduction agent usually contains surfactant components. These compounds form a adsorption layer in water. This adsorption layer can reduce the surface tension of water, making water easier to contact solid particles…

HEDP (1-hydroxye ethyl-1,1-two pyrine) is a kind of organic acid chemical, also known as hydrogenated loosening. It is a chelating agent widely used in the fields of water treatment, industrial cleaner and stuffing agent. The molecular formula of HEDP is C2H8O7P2, and its chemical structure contains two pyrite groups and a hydroxyethyl group. These functional…
HEDP solid belongs to high -purity goods, suitable for winter severe cold areas; especially for cleaning liquid and daily chemical additives of the electronic industry. HEDP can be mixed with water. Under high pH, it is still very stable. Microcximity is not polluting. The following 200OC has excellent anti -scale anti -scale effects. It is…
HEDP (1-hydroxye ethyl-1,1-two pyrine) can exist in the form of solid and liquid. They have some differences in terms of nature and application: Profit: HEDP solids usually exist in the form of powder or particles, while HEDP liquid exists in the form of solution. Solubility: The solubility of HEDP solid in water is low, and…
HEDP (1-hydroxyethyl-1,1-diic acid) and EDTMPA (ethyleine tetharine) are two commonly used chelated agents, which are widely used in scaling and scale resistant agents. Although they all have good chelating performance, in different application scenarios, their effects may be different: HEDP: HEDP is an organic acid dirt -resistant agent, which is characterized by its strong chelating…
HEDP (1-hydroxyethyl-1,1-diphosphonic acid) is a commonly used cleaning agent additive that has excellent scale inhibition, corrosion inhibition, and dispersion effects. It can help cleaning agents better remove scale and dirt, while protecting cleaning equipment from corrosion. The dosage of HEDP in cleaning agents generally needs to be adjusted and determined based on specific circumstances. The…
