The additives in equipment production can be divided into coagulants and slowing agents.The choice of this depends on the process of manufacturers.Slow-cranked (BA-3) emulsifier and SBR modified agent are two materials that need to be prepared by production modified emulsion asphalt. The amount of asphalt weight is 1-1.2%and 3-6%.1-2 days on-site preparation.Acid stones or low -temperature construction should be emulsified as pomonicized asphalt, alkaline stone or cement, and lime should be emulsified as asphalt.
Food and appropriate additives are indispensable accessories in the production of emulsification asphalt equipment. Therefore, be careful when selecting auxiliary materials. In addition, other things need to be used in equipment production.Continue to follow the editor to look down on other attention requirements for the construction of emulsion asphalt equipment:
What are the requirements for the fusion of water and asphalt with emulsification asphalt equipment. The surface tension of asphalt and water changes greatly, and it will not be mixed at room temperature or high temperature.However, when the emulsion asphalt equipment is high-speed mechanical centrifugal, shear, and collision, the emulsion asphalt equipment makes it forming particles with a particle size of 0.1-5 microns, which is scattered in the water agglutination containing surfactants (emulsifier stabilizers).Emulsion asphalt equipment 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.
The precautions in the use of emulsion asphalt equipment are generally summarized as follows:
1. Before spraying, check whether the position of the valve is correct.The hot asphalt added to the emulsion asphalt equipment 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 asphalt in the asphalt equipment in the burning device, the asphalt height should be higher than the upper plane of the burning room, otherwise the combustion chamber will burn out.Emulsion asphalt equipment cannot be full.The lid of the refueling mouth 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 rear console can only control the improvement of the nozzle.
The above is the decomposition method of the construction precautions of emulsion asphalt equipment. Each point of construction precautions is ends, because all design and construction cannot be mixed.Therefore, the relevant introduction of this content is for your reference only.
