1. Plant asphalt is a by-product in the production process of biodiesel, which is a deep-processing product for enterprises to improve the comprehensive utilization of waste oil, achieve emission reduction in the production process, and improve the profitability of enterprises.
2. Main uses: production of casting binder, rubber softener, cement prefabricated spacer, black printing ink, asphalt coating, coating, surface activated carbon, leather additives and heavy fuel, etc. The use of vegetable asphalt is very wide, just as a casting binder, it has a broad market prospects. Relevant data show that the annual output of China's foundry industry ranks first in the world, which is the sum of the output of the United States and Germany; However, it is only the advantage of mass production, and the technical content is still at a low and medium level, among which quality and environmental protection are the primary issues. At present, China's casting binders are mainly divided into organic resins and inorganic binders. The former is a non-renewable resource and produces a large number of toxic substances such as dioxins during use, which seriously pollutes the environment. The latter production of castings, one is the high cost, the second is the product quality there are large defects. Therefore, the use of plant bitumen from biological raw materials to make casting binders has certain advantages.
