Dicyandiamide Usage:

1. As a raw material for strontium salts and melamines. Various guanidinium salts can be produced by reacting dicyandiamide with an acid. The phenyl melamine diamine obtained by the reaction of dicyandiamide and phenyl nitrile is an intermediate of a coating, a laminate and a molding powder.
2. Used as a dye fixing agent, dicyandiamide resin prepared by the reaction of dicyandiamide and formaldehyde, which can be used as a dye fixing agent.
3. Dicyandiamide fertilizer, dicyandiamide compound fertilizer can control the activity of nitrifying bacteria, adjust the transformation speed of nitrogen fertilizer in soil, reduce nitrogen loss and improve fertilizer use efficiency.
4. As a fine chemical intermediate. It is used in medicine to prepare cerium nitrate, sulfonamides, etc.; it is also used to prepare thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive and the like. The pharmaceutical intermediate 5-azacytosine is obtained by reacting dicyandiamide with formic acid.
5. This product is also used as a rubber vulcanization accelerator. It is also used as a raw material for preparing strontium salts, dye fixing agents, dicyandiamide fertilizers, sulfonamides, thiourea, nitrocellulose stabilizers, and steel surface hardeners.
6. Used as epoxy latent curing agent, formulating one-component epoxy adhesive, which can improve the mechanical and physical properties of the resin; reference dosage 4-12 parts by mass, 100g epoxy resin complex application period 6~12 Months. The curing conditions were 160 ° C / 30 min, and the heat distortion temperature was 125 ° C. The dicyandiamide resin obtained by the reaction with formaldehyde can be used as a post-treatment fixing agent for direct dye fixing agent, cotton and silk dyeing; as a starch additive, it can improve its fluidity; as a nitrogen fertilizer additive, it can be improved Fertilizer effect. It is also used in the manufacture of raw materials such as adhesives, melamine, pharmaceuticals, pesticides, dyes, coatings, explosives, synthetic detergents and barium salts. Also used as rubber vulcanization accelerator, steel surface hardener, paper flame retardant, anti-fungal agent, etc.
