Urea, also known as carbon amide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is a white crystal. It is currently the nitrogen fertilizer with the highest nitrogen content and one of the simplest organic compounds. Let's take a look at the applications of urea in various industries, shall we?
Urea application field
1. In the petroleum industry, urea is used as a dewaxing agent in the petroleum refining process.
2. In the pharmaceutical industry, urea can be used to make dozens of chemicals, such as nitrofurazone, urea esters, barbiturates, luminal and diuretics; sometimes as the main raw material, sometimes as an additive.
3. In the organic synthesis industry, urea is used to prepare polymer synthetic materials. Urea-formaldehyde resins are used in the production of plastics, paints and adhesives, and can also be used as raw materials for melamine resins.
4. In the textile industry, urea is used to produce polymers containing urea rhythm, which is the raw material of nylon, one of the synthetic fiber varieties. Urea is also used as a softener for fiber products.
5. Urea is used in combination with organic fertilizers, phosphorus and potassium fertilizers and trace element fertilizers in agriculture to maintain soil nutrient balance, maximize nutrient utilization, and increase fertilizer production.
6. Urea is usually used in tanning and pigment production. Urea is also used abroad as a pollution control agent to absorb pollutants and protect the environment. The free ammonia released by the decomposition of urea can inhibit the production of microorganisms and prevent the grains from becoming moldy during storage.
7. Urea can be further processed into melamine, and then condensed with formaldehyde to form melamine formaldehyde resin (commonly known as melamine resin). As one of the important chemical raw materials, the resin is widely used in coatings, plastics, wood processing, papermaking, textiles and other fields.
8. Urea can also be used in the manufacture of coating cosolvents, fiber softeners, anti-icing agents, petroleum refining agents, plastic foaming agents, fabric anti-wrinkle agents and bleaching agents. In MSG production, urea is also used as a nitrogen source for fermenting bacteria. In addition, urea is used as a stabilizer in the manufacture of explosives and as a blowing agent in mineral processing.
