| 摘要 |
Aqueous urea and/or aqueous urea condensate and/or aqueous urea composition may be utilized to fight grass, forest, building, and other flammable organic material by applying it to these flammable organic materials. The aqueous urea and/or aqueous urea condensate and/or aqueous composition may also be incorporated into flammable materials such as solid and foam plastic and natural materials. Aqueous urea composition are produced by adding and mixing carbon auxiliaries, such as phosphorus containing compounds, metal containing compounds that will accelerate carbonization, heat reflector, surfactant and fillers to the aqueous urea.
