In-Stock Humic Acid Flake Large And Shiny
1. Product Introduction
Premium Flake Sodium Humate
Our flake sodium humate is extracted from mineral-rich weathered coal, delivering high concentrations of active functional groups for broad-spectrum applications.
Regional Sourcing:
-
Type I: Exclusive weathered coal from our self-owned mines in Fukang, Xinjiang
-
Types II & III: Premium weathered coal from Inner Mongolia
Product Characteristics: Glossy black flakes with excellent water solubility, designed for prolonged suspension and gradual dissolution, ensuring sustained performance across diverse applications.
Manufacturing Process: Raw coal undergoes initial crushing, followed by alkaline extraction with NaOH solution at 90°C for 2 hours with continuous agitation. The reacted solution is precipitated to eliminate impurities from unreacted materials. The purified sodium humate stock solution is then transferred to a drum dryer, where it forms an instant liquid film on the drum surface. This film solidifies into uniform sheets that dry and automatically peel off during rotation. Final air-flow cooling and screening yields glossy black flakes with minimal impurities.
Environmental Compliance: Featuring closed-loop condensate recovery and dual-stage cyclone and bag filtration for dust and exhaust gas treatment, our process meets stringent clean production standards.
