1. Packaging Specifications GLDA·Na₄ is typically packaged in the following forms to ensure stability and ease of transport: Solid (Powder/Granules): 25 kg/bag: Multi-layer kraft paper bags with polyethylene (PE) inner lining. 500 kg or 1000 kg/jumbo bags: For bulk industrial use (moisture-proof). Liquid Solution (Aqueous, ~40% concentration): 200 kg/HDPE plastic drums (high-density polyethylene, corrosion-resistant). 1000 kg/IBC…
TTA•Na (Tolyltriazole Sodium Salt) functions as a highly effective corrosion inhibitor, primarily for copper and its alloys, through a combination of chemical adsorption, film formation, and electrochemical passivation. Below is a detailed breakdown of its application principles: 1. Core Mechanism: Adsorption & Film Formation Chemisorption on Metal Surfaces: TTA•Na molecules adsorb onto copper surfaces via coordination bonds between the triazole nitrogen…
Yes, DDBAC (Didecyldimethylammonium Chloride) and BKC (Benzalkonium Chloride) are toxic at certain concentrations, particularly to aquatic life and upon prolonged human exposure. However, their toxicity depends on dosage, exposure route, and application. Below is a detailed breakdown: 1. Toxicity Profile of DDBAC/BKC (1) Human Health Effects Exposure Route Effects Safety Precautions Skin Contact Mild to…
The main purpose of Didecyldimethylammonium Chloride (DDAC) is as a broad-spectrum antimicrobial agent and disinfectant, widely used for its biocidal, surfactant, and preservative properties. Below are its key applications: 1. Primary Uses of DDAC (1) Disinfection & Sanitization Healthcare: Hospitals, clinics (surface disinfectant against bacteria, viruses, fungi). Food Industry: Sanitizing equipment, processing areas (effective against E. coli, Salmonella, etc.). Household/Public Spaces:…
The choice between solid (sodium salt) and liquid forms of ATMP depends on specific application needs, handling preferences, and cost considerations. Below is a detailed comparison to guide your decision: 1. Solid ATMP (Sodium Salt, e.g., ATMP·Na₅) Advantages Stability & Shelf Life: Longer shelf life (2–3 years vs. 1–2 years for liquid) due to lower…

Proper storage of ATMP (liquid or solid form) is essential to maintain its effectiveness and ensure safety. Below are the key guidelines: 1. Storage Conditions Parameter Requirement Reason Temperature 5–40°C (avoid freezing or high heat) Prevents crystallization (solid form) or degradation. Container Plastic (HDPE) or Stainless Steel ATMP is acidic (pH ~2) and can corrode carbon steel. Sealing…
Distinguishing the quality of Hydroxyethylidene Diphosphonic Acid (HEDP) requires evaluating its chemical purity, physical properties, performance efficiency, and stability. Below are key methods and criteria to assess HEDP quality: 1. Key Quality Indicators (1) Active Content (Purity) High-Quality HEDP: Liquid form (50–60% concentration): Active content ≥50%. Solid form (crystalline powder): Purity ≥95%. Test Methods: Potentiometric Titration: Measures phosphonic…
PAA (Polyacrylic Acid) is a widely used water-soluble polymer in water treatment, detergents, and dispersants. Proper packaging and storage are crucial to maintain its stability and performance. 1. Packaging Specifications Aspect Requirements Material Polyethylene (PE) drums or plastic-lined steel containers (corrosion-resistant). Form Liquid (typically 30–50% aqueous solution) or solid powder. Sealing Airtight to prevent moisture absorption (powder) or…
Using polyacrylic acid (PAA) to treat heavy metal ions (e.g., Pb²⁺, Cd²⁺, Cu²⁺, Hg²⁺) in industrial wastewater leverages its carboxylate (–COO⁻) chelation and electrostatic adsorption capabilities. Here’s a step-by-step guide to optimize the process: 1. Mechanism of PAA Chelation Carboxylate Binding: PAA’s –COO⁻ groups form stable complexes with metal ions via bidentate or bridging coordination, especially with transition metals (e.g., Cu²⁺, Ni²⁺) and heavy metals (e.g.,…
PESA is a green, biodegradable scale inhibitor and chelating agent widely used in agriculture for irrigation systems, soil conditioning, and nutrient management. Below are its key applications: 1. Irrigation System Maintenance Prevents Scale & Clogging in Drip/Trickle Irrigation Problem: Hard water (high Ca²⁺, Mg²⁺, HCO₃⁻) causes mineral deposits, clogging emitters. Solution: PESA (5–20 ppm) inhibits CaCO₃, CaSO₄ scale, improving water flow….
