50 KG/Drum FeCL3 Ferric Chloride Used for Etching and Water Treatment

Introduction

The chemical formula is FeCl3, and the appearance is black-brown crystals (also in the form of flakes). It is easily deliquescent in humid air and easily hydrolyzed in solutions with low acidity to form iron hydroxide colloid. It is easily soluble in water, methanol, ethanol, but insoluble in glycerol (glycerol). When dissolved in water, it releases a lot of heat to form a coffee-colored or brown-yellow acidic solution. Hexahydrated ferric chloride with water of crystallization can be precipitated from the solution.

Ferric chloride is an important iron salt, which is widely used in metal etching, sewage treatment, coagulant, catalyst, oxidant, mordant, medicine and other fields.

Parameter

Parameter

Ferric chloride is mainly used in metal etching and wastewater treatment due to its oxidizing properties and flocculation mechanism in aqueous solution.
1. Metal etching: Etching of materials such as copper, stainless steel, and aluminum, including hardware etching. Etched products include eyeglass frames, clocks, electronic devices, nameplates, etc.;
2. Sewage treatment: Treatment of low-oil raw water, high-toxicity, high-nitrogen content and high COD (chemical oxygen demand) wastewater, etc., with good effects and low prices, but it will also cause the water to turn yellow;
3. Dye industry: Ferric chloride can also be used for printing and dyeing roller engraving, electronic industry circuit board and fluorescent digital tube production, and oxidant for indicosin dye dyeing;
4. Construction industry: It can be used to prepare concrete to enhance the strength, corrosion resistance and waterproofness of concrete, and can also be prepared with ferrous chloride, calcium chloride, aluminum chloride, aluminum sulfate, hydrochloric acid, etc. to make concrete waterproofing agent;
5. Inorganic industry: used to manufacture other iron salts, inks or catalysts (such as catalytic H2O2 decomposition);
6. Metallurgical industry: used as a chlorination leaching agent for extracting gold and silver;
7. Organic industry: used as catalyst (such as esterification reaction), oxidant and chlorinating agent;
8. Glass industry: used as hot colorant for glassware;
9. Soap industry: used as coagulant for recovering glycerol from soap waste liquid;
10. New energy: iron source for lithium iron phosphate (LiFePO4), the positive electrode material of lithium-ion batteries.

Precautions

Leakage Emergency:
Isolate the leaked contaminated area and set up warning signs around it. It is recommended that emergency response personnel wear gas masks and chemical protective clothing. Do not directly contact the leaked material, avoid dust, and collect and transport it to a waste treatment site for disposal. Dissolve it in a. water, b. acid, or c. oxidation to an aqueous solution, then add sulfide to cause precipitation reaction, and then discard it. It can also be rinsed with a large amount of water, and the diluted washing water is put into the wastewater system. If a large amount of leakage occurs, collect and recycle it or dispose of it harmlessly.
Protective Measures:
Respiratory system protection, when you may be exposed to its dust, you should wear a dust mask. Wear a gas mask when necessary.
Eye protection, wear chemical safety glasses.
Protective clothing, wear work clothes (made of anti-corrosion materials).
Hand protection, wear rubber gloves.
Others, after work, take a shower and change clothes. Store clothes contaminated by toxic substances separately and wash them before use. Maintain good hygiene habits.
