Here is a detailed explanation of the protective measures for PESA (Polyepoxysuccinic Acid). The term “protective measures” can be interpreted in two ways, and this answer will cover both: How PESA protects industrial systems (its function as a scale inhibitor). Safety measures for handling and protecting oneself from PESA (its material safety). 1. How PESA Protects Industrial Systems…
Here is a detailed overview of the physical properties of GLDA·Na₄ (Tetrasodium Glutamate Diacetate). GLDA·Na₄ is the tetrasodium salt of GLDA, which is the most common commercial form due to its high solubility and stability. It is a next-generation, readily biodegradable chelating agent derived from a natural, renewable feedstock (fermented sugar). Its physical properties are typically described…
HPAA (Hydroxyphosphonoacetic Acid) is a highly effective and versatile organic phosphonic acid-based water treatment chemical. It’s known for its excellent scale and corrosion inhibition properties, particularly in challenging water conditions. Here is a comprehensive guide on how to use HPAA effectively and safely. 1. Understanding HPAA’s Strengths (Why Choose It?) Before using it, know why HPAA…

DDBAC (Didecyldimethylammonium Chloride), a quaternary ammonium compound (QAC), is widely used as a disinfectant, surfactant, and biocide due to its strong antimicrobial activity and surface-active properties. 1. Key Properties of DDBAC (1) Chemical Structure Chemical Name: Didecyldimethylammonium Chloride CAS No.: 7173-51-5 Molecular Formula: C₂₂H₄₈ClN Appearance: Colorless to pale yellow viscous liquid Solubility: Soluble in water (forms a clear…
Corrosion inhibitor: EDTMPS forms complexes with metal ions, inhibiting metal corrosion and oxidation, thereby acting as a corrosion inhibitor. It effectively protects metal equipment, pipes, and systems from corrosion and damage. Scale remover: EDTMPS has excellent dissolution and removal capabilities for carbonate and sulfate scale in hard water containing calcium and magnesium. It can effectively…
EDTMPS is the same as EDTMPS; they are actually the same substance, namely sodium ethylene diamine tetra (methylene phosphonic acid) pentasodium salt. Therefore, there is no difference between EDTMPS and EDTMPS; they are simply different names for the same water treatment agent. This substance is a highly effective corrosion inhibitor and scale inhibitor, suitable for…
