However, the scale of development with the needs of our domestic bitumen market compared to China bitumen market is still in short supply in the state, especially those high-end asphalt market in China is to be talented people and explore, our ordinary road asphalt production many manufacturers of asphalt, but the professional manufacturer of asphalt is relatively small, we should gradually improve the professional asphalt manufacturers, to make up for the growing market demand for professional asphalt. (5) emulsification method: surface tension of water is a great difference between the asphalt and, at room temperature or elevated temperatures are not miscible with one another. But when the asphalt by high-speed centrifugation, cut, blow mechanical action, making it the particle size of 0.1 to 5 microns, and dispersed to contain a surfactant (emulsifier - stabilizer) in an aqueous medium pitch spot, Since the emulsifier adsorbed on the asphalt particles can be oriented surface, thereby reducing the interfacial tension of water and bitumen, asphalt particles capable of forming a stable dispersion in water wholesale bitumen, which is a water-in-oil emulsion. This dispersion was dark brown, asphalt dispersed phase, water as the continuous phase, having good fluidity at room temperature. In a sense emulsified asphalt with water to "dilute" the asphalt, thus improving the liquidity of the asphalt. Bitumen prices, asphalt, three-level chemical provided by Jinan three ping Chemical Co. Jinan three ping Chemical Co. (www.sanpinghuagong.com) strong, credible, in Jinan, Shandong chemical products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead three levels of chemical into the brilliant and you work for a better future!
