核心 产品特点

1. Superior Reductive Acid Resistance: Specializes in resisting hydrochloric acid (any concentration/temperature under normal pressure), sulfuric acid (low-to-medium concentration), phosphoric acid and organic acids (acetic acid, formic acid). Low carbon (≤0.02%) and silicon content prevents intergranular corrosion, while high molybdenum (26–30%) forms a dense passivation film to resist chloride-induced stress corrosion cracking—ideal for reductive harsh environments.

2. Mechanical Performance: Tensile strength ≥690MPa, yield strength ≥310MPa; excellent toughness and structural stability at ≤760℃ continuous service, no brittle fracture under cyclic acid exposure and temperature fluctuations.

3. 40Mesh Specific Advantages: Medium-coarse precision with 0.45–0.50mm aperture, balances particle retention and fluid throughput. Separates 450–500μm impurities, suitable for high-flow filtration in reductive acid media with high solid content; uniform mesh structure ensures long-term filtration consistency without clogging easily.

Main Application Fields (40Mesh Focus)

1. Chemical Industry: Filtration of hydrochloric acid storage/transport pipelines, medium-concentration sulfuric acid processing equipment, organic acid (acetic/formic acid) synthesis reaction 釜 screening, phosphoric acid raw material impurity removal.

2. Metallurgy & Mining: Wet smelting acid leaching solution filtration (non-ferrous metals like nickel/cobalt), corrosive slag separation in acid-based mineral processing, high-solid-content reductive acid fluid screening.

3. Pharmaceutical & Fine Chemical: Pretreatment of organic acid raw materials in drug synthesis, filtration of reductive catalyst-containing solutions, intermediate product coarse filtration in fine chemical production.

4. Environmental Protection: Coarse filtration of high-concentration acidic wastewater (e.g., pickling wastewater), impurity removal in reductive industrial waste gas washing liquid, acid-based waste liquid pretreatment before deep treatment.
