Construction Asphalt residue oil is rectified, depending on the degree of refining, processing from further oxidation. At room temperature into a liquid, semi-solid or solid. Asphalt color black and shiny, with high temperature resistance. Petroleum bitumen can be classified according to the following system: according to the production methods are divided into: straight asphalt, solvent deasphalting oil asphalt, blown asphalt, blended asphalt, emulsified asphalt, modified asphalt; divided according to morphology: liquid asphalt, solid asphalt, dilution, emulsion, modified product; use is divided into: asphalt road, construction of asphalt, waterproof asphalt, use or function name to a variety of special asphalt. Construction Asphalt general are vacuum residue as raw materials, increase its viscosity with a hair oxidation large supply 10 Construction Asphalt softening point above 90 ℃ penetration of 5--40 (0.1mm) of the establishment of asphalt Asphalt roads and specifications are the same as in penetration to divide grades. The main control targets for the penetration of the building on the 10th pitch, softening point and viscosity. In the long-term supply of petroleum materials of the same species on the 10th pitch of the manufacturers, the smaller supply of Grade 10 construction bitumen, the harder, the greater the grade, the more soft asphalt. At the same time as the grade increases, increase penetration. Reduce the viscosity of bitumen ductility increases, plastic softening point increase to reduce the temperature sensitivity increases for roofing projects, should be taken to prevent excessive softening, according to the hot season testing, asphalt surface temperature reached the level higher than the maximum local temperature 25--30 ℃. To prevent summer drip, high softening point pitch roofing material should be less than the highest possible local temperature above 20 ℃. Building asphalt manufacturers, Anhui Province on the 10th Construction Asphalt road should be raw material provided by the Shandong new Ze Rui New Material Technology Co., Ltd .. Shandong Zerui New Material Technology Co., Ltd. (www.maidiping.net) strong, credible, in Dongying of site construction materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Zerui new material into the brilliant and you work for a better future!
