¥1100.00
Product Name: Sodium Sulfide
Chemical Formula: Na₂S
Key Features: Yellow to reddish flake or solid, strong alkaline, readily soluble in water, distinctive odor, strong reducing agent.
Main Applications by Industry:
Leather Processing: For unhairing and liming of hides, essential in the beamhouse stage of leather tanning.
Water Treatment: As a heavy metal precipitant to remove metals (e.g., mercury, copper, lead, zinc) from industrial wastewater.
Pulp & Paper Industry: As a key component in kraft pulping process (sulfide liquor) to break down lignin for paper production.
Textile & Dyeing: Used as a reducing agent in sulfur dyeing processes and for removing excess dyes from fabrics.
Mining & Ore Flotation: As a depressant and pH regulator in the flotation separation of non-ferrous metal ores (e.g., copper, molybdenum).
Chemical Synthesis: As raw material for producing dyes, sulfur compounds, thiochemicals, and other organic chemicals.
Petroleum Refining: For removing mercaptans and other sulfur compounds in refining processes (sweetening).
Photography: As a component in photographic developers and toners.
Handling & Safety:
