What Are The Advantages And Disadvantages Of Smelting Asphalt?

Asphalt is widely used as the main raw material of battery sealing agent because of its good insulation, viscosity and mobility, low melting point and low cracking resistance at low temperature. But in the process of asphalt smelting and boiling, transportation, addition and sealing pouring of liquid asphalt, a lot of asphalt smoke is produced and spilled out, even liquid asphalt. Except for the concentrated pollution sources and high concentration of smelting and boiling, the others are characterized by open pollution sources, low concentration and inconvenient treatment.

Asphalt is a hydrocarbon compound with complex chemical composition. Especially, the benzoricin contained in asphalt is a strong carcinogen, which is harmful to workers. Workers work long-term under the surroundings of asphalt smoke, light cough, dizziness and nausea; In severe cases, workers are susceptible to occupational diseases such as black and purple skin, visual impairment, boils, eczema, skin allergies and so on. In addition, in the transportation and addition of liquid asphalt, little attention will be paid to the risk of burns.

Melting point of asphalt:

Asphalt is a mixture, there is no fixed melting temperature, so there is no melting point, the general index is the softening point, the composition of different softening points are different. The softening point of petroleum asphalt by distillation method is more than 100 C, and the penetration is about 90-200.
