(1) Highway chemical production line
After 6 months of design, optimization, debugging, and modification by an expert team, the highway chemical production line was successfully put into operation in March 2023. The main equipment of this production line consists of seven reaction vessels, one CNC room, and one PLC software system. There are four enamel reaction vessels and two stainless steel reaction vessels with a capacity of 5 tons in the hardware equipment, and another stainless steel reaction vessel with a capacity of 3 tons. The device is equipped with a reaction, heating, and cooling system, which is automatically heated by thermal oil and cooled by refrigerant. The introduction of PLC automatic control technology into software equipment, through the use of fully editable logic controllers, relying on microelectronics technology and combined with digital technologies such as computers and communication, achieves online control of production processes such as automatic temperature control, automatic control of reaction time, and automatic detection. The automated system is upgraded to a real-time controllable intelligent system, making the production process more reasonable and efficient. From the perspective of process design and equipment configuration, the Longteng Road highway chemical production line is of first-class level in China, which can meet the production of various highway chemicals such as quaternary ammonium salt emulsifiers, micolin surfactants, amide anionic emulsifiers, anti stick isolation agents, warm mix agents, and regenerants. Producing different types of chemical agents at full capacity, with a minimum daily output of 20 tons, and an annual output that can meet the demand of the national market.
