Bitumen is a complex mixture of hydrocarbons with different molecular weights and their non-metallic derivatives. It is a kind of organic liquid with high viscosity, which mostly exists in liquid or semi-solid petroleum form. Its surface is black and can be dissolved in carbon disulfide and carbon tetrachloride. Asphalt is a kind of waterproof moistureproof and anticorrosive organic cementitious material. Asphalt can be divided into coal tar pitch, petroleum pitch and natural pitch: coal tar pitch is a by-product of coking. Petroleum pitch is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore deposits or deposits on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving.ProgramParameterColorBlackTexture of materialPVCSurface treatment processSpraying paintedPurposeIndustrial UseShapeRollCore materialMineral wool ceilings
