Properties: black viscous liquid or paste; mainly used in the production of foundry binders, rubber softeners, cement prefabricated release agents, black printing inks, asphalt coatings, coatings, surface activated carbon, leather additives and heavy fuels, etc. Wait. Index: acid value ≤45 4. Packing method: iron drum 180 kg/barrel or tank truck. Vegetable asphalt has a wide range of uses. Just as a casting binder, it has broad market prospects. Relevant data show that my country's foundry industry reached 25 million tons in 2005, ranking first in the world, and it is the combined output of the United States and Germany; but it is only the advantage in mass production, and the technical content is still at a low-to-medium level. Among them, quality and environmental protection are at a low level. main problem. my country's foundry binders are mainly divided into organic resins and inorganic binders. The former is a non-renewable resource, and a large number of toxic substances such as dioxins are produced during use, which seriously pollutes the environment. The castings produced by the latter are one of high cost, and the other is that the quality of the product has major defects. Therefore, the use of plant pitch derived from biological raw materials to make casting binders has certain advantages.
