Calcium Cyanamide for Chemical

The chemical uses of calcium cyanamide include:

1. Chemical raw material: Calcium cyanamide is an important raw for synthesizing guanidine compounds and melamine. Under specific conditions, calcium cyanamide can undergo a polymerization reaction to form melamine, which is used to produceamine formaldehyde resin. This resin has the characteristics of water resistance, heat resistance, etc., and is applied to plastics, coatings, adhesives and other. 

2.Metallurgical industry: During steelmaking, calcium cyanamide can react with harmful impurities such as sulfur and phosphorus in molten steel to form sulfide andide that are easy to remove, thus improving the purity and quality of steel and improving the mechanical properties of steel.

3.Organic synthesis catalyst: In some organic chemical reactions, cyanamide can be used as a catalyst or co-catalyst to promote the progress of the reaction and improve the efficiency and selectivity of the reaction.

4.Other uses: Calcium cyanamide can also be used as a nitriding agent for steel, a reagent for treating gold and silver ores, a purifying agent for waste (used for adsorption of nitrogen oxides), a reagent for removing formaldehyde from wastewater, a raw material for industrial cyanide (for preparing sodium cyan, dicyandiamide, etc.), and a raw material for pesticides and explosives, etc.

It should be noted that when using calcium cyanamide in applications, it is necessary to pay attention to its reaction with water and acid, which may produce irritating gases. Protective measures should be taken during operation, and proper storage should be to avoid changes in its properties affecting the use effect.

Specification

Packing

Plastic woven bags lined with polyethylene plastic bags, each with a net weight of 1000kg. The package is marked " Toxic substance ". It is inorganic and has Toxic substances. Dangerous code: GB 4.3 class 43507. UNN0.1403; Imdg code page 4336, category 4.3.

Storage

It should be stored in a cool, well-ventilated, and dry warehouse. Pay attention to moistureproof and don't pile up against the wall. Handle with care when loading and unloading to prevent the package from being damaged.

Precautions for use

Wear work clothes, masks, and gloves when handling. Rain-proof and waterproof equipment shall be provided during transportation. In case of fire, sand and dry powder fire extinguishers can be used to put out the fire, but water cannot be used to save it.

Toxicity and protection

it has systemic toxic effects, especially on the vascular motor center, respiratory center, and blood, resulting in vegetative neurasthenia syndrome and dysfunction of endocrine organs and basal metabolism. After acute poisoning, there may be organic neurological diseases, limb weakness, and subsequent polyneuritis. The lethal dose to humans is 40 ~ 50g. Chronic poisoning often occurs with asthmatic bronchitis and bronchial wheezing, chronic gastritis and hepatitis, low blood pressure, myocardial malnutrition, sexual dysfunction, thyroid and adrenal dysfunction, and dry skin, itching, and dermatitis. Falling into the eyes can cause suppurative conjunctivitis, corneal ulcer, and turbidity. The emergency treatment is to keep quiet. When the eye mucosa is damaged, wash it carefully with water or normal saline, and then drop 1% novocaine solution into the eye; When acute dermatitis occurs, a wet bandage made of lead water can be given, and the liquid can be tightly applied; For minor burns, apply 1% ~ 2% gentian violet, methylene blue or bright green alcohol solution to the injured part. For minor burns, tinctures of iodine, nitrofurazone, and sterilization tape can be used. Staff should wear overalls, gloves, protective glasses, and masks when working. Apply a non-irritating fat ointment to the skin of the hand first. Strictly observe personal hygiene measures.
