How to choose the applicable auxiliary materials for the construction of the asphalt can?
The fillers used in construction are generally divided into two types: chemical activity and non -chemical activity.In the production of equipment, the stability of the mud mixture can be improved, the speed of milk breaking is accelerated or slowed, and the strength of the seal layer is improved.When adding chemical -activated fillers, the reaction and compatibility of filler and minerals and modified emulsion asphalt should be fully considered.Acid stones or low -temperature construction should be emulsified as desirable, alkaline stone or cement.Proper additives are indispensable accessories in construction production, so be careful when selecting auxiliary materials.
The requirements for the integration of water and asphalt in asphalt tank construction
The surface tension of asphalt and water changes greatly, and it will not be mixed at room temperature or high temperature.However, when the construction is high-speed mechanical centrifugal, shear, and collision, the asphalt tank construction makes it forming particles with a particle size of 0.1-5 microns, scattered in the water agglutination containing surfactants (emulsifier stabilizers).Emulsions can be adsorbed on the surface of the equipment construction, reducing the interface tension of water and asphalt, and dispersing asphalt particles in water agglutination containing surfactants (forming a stable decentralized system in water).The asphalt tank construction is a kind of water -based oil emulsion.The decentralized system is brown, asphalt is decentralized, water is continuous phase, and room temperature is good.
Precautions in the design of asphalt can
1. Before spraying, check whether the position of the valve is correct.The thermal asphalt added during the construction of the asphalt tank should work within the range of 160 ~ 180.This heating device can be used for long -distance transportation or running for a long time, but cannot be used as a melting oil furnace.
2. When using the asphalt in the construction of the burner, the asphalt height should be higher than the upper plane of the burning room, otherwise the burning room will burn out.The lid of the refueling mouth during the asphalt tank should be tightened to prevent asphalt from overflowing during transportation.
3. When using the previous console, the switch should be set to front control.At this time, the console can only control the improvement of the nozzle.
