Cleanliness of emulsified asphalt is very important. Unclean emulsified asphalt will affect the quality of construction. Air into the emulsified asphalt, emulsified asphalt will be breaking. Cation emulsified asphalt in contact with the metal, will be breaking. If emulsified asphalt residue in the pump body, not cleaned, it will plug the pump. Line residual emulsion, not cleaned, it will cause pipe blockage. The better performance of emulsified asphalt, more thorough requiring of cleaning. Storage equipment must be cleaned thoroughly before the storage.
Cleaning process as below steps:
a）Flushed with high-pressure water pipes；
b）Cleaning with kerosene. Not allowed to use diesel or other cleaning solution, these fluids can not dissolve asphalt, incompatible with the emulsion, resulting emulsified asphalt emulsion breaking, inconvenient of cleaning;
c）Finally, rinse with water pipes. Can not brush the inside bucket of emulsified asphalt;
d）If the pump or line pitch has been blocked, it will be heated slowly, and then washed. You can not use the heating pipes, as it will emulsified asphalt emulsion break;
e）Soaked with kerosene pump time up to an hour or more；
f）After the blockage is cleared, rinsed with water pump again.
Generally, emulsified asphalt is stable during transport . The most common problem is the air into emulsified asphalt , causing emulsified asphalt emulsion breaking, especially CRS emulsion, the air is able to activate a large precipitate particles generated emulsified asphalt, occurs the emulsion breaking phenomenon.
For the main requirement is to ensure the correct use of the pump, and reasonable transportation method. In cold weather, use the pump to heat , a clean bucket, checking various conditions of loading. Put the emulsified asphalt in a clean buckets and closed for transportation.
Emulsified asphalt is a chemical substance that can not be mixed with other types of emulsified asphalt products, but also can not be mixed with other chemicals. Iron rust, dirt, plants or other extraneous materials are not allowed to mix. For the cationic emulsion is particularly important because of its effect will happen with the debris generated demulsification phenomenon.
