| 摘要 |
The present invention is related to a fuel paste that uses a hydrophobe pyrogenic silica, as a viscosifier, compatible with combustible organic liquids for providing thixotropic properties that facilitate and improve the dosage and burn of the fuel paste. Such properties are shown by the viscosity drop at a constant shearing speed and by the viscosity drop due to the increase in the shearing speed. The present invention may be performed with additives that provide heat and odour according to the required applications; the manufacture of the invention is easy and may be formed with biodegradable and environmentally friendly ingredients. In addition, the present invention has the following characteristics: an improved flame life, optimum performance in humid environments, safety and handle due to its high flashpoint (higher than 95°C), and specially the capacity of being used after being wet; all these characteristics were proved by comparative tests of performance with state-of-the-ar t products and standardized methodologies for the flashpoint case. The present invention may keep the flame burning by the required time for surpassing, in terms of duration, the products currently available on the market; it also may burn humid coal, which has not been previously presented by the state-of-the-art products.
