Maleni: "Innovation and Upgrading" of Jiuma Expressway

Since its birth in 1899.，The Malani brand has been pursuing one thing.：Close to customer's application needs， Innovate with customers。In the middle of this year，At the construction site of Jiuma expressway in Northwest Sichuan，For special construction environment，According to the innovative thinking proposed by customers，Maleny is anxious for his clients.，Think what the customer wants，Help customers with their needs，Set up R & D team with customers，In the fastest possible time，An intelligent system for adding asphalt additives is developed.，Perfect solution to the needs of customers。

Jiuma Expressway is 219 kilometers long.，The total investment is estimated to be nearly 30.2 billion yuan，It is located in the marginal zone of the transition from the Sichuan Basin to the Qinghai-Tibet Plateau.，It passes through the ecological demonstration area of Northwest Sichuan.。As the first high-altitude plateau expressway in Sichuan,，Through the grasslands along the way、Wetland area，The ecological environment is extremely fragile，Sichuan Communications Construction Group, the construction party, has put forward extremely high requirements for environmental protection construction.。
Facing stringent ecological protection requirements，MarleneMAC320 is selected in the asphalt mixing station of Sichuan Communications Construction Group，Stand out，It has passed the strict environmental protection standards of the project.。After being put into production，The indicators have been verified in many ways.，While helping customers to do a good job of road paving，The task of protecting the local ecological environment has been accomplished.。

Building roads is a matter of interlocking links.，From construction personnel to construction equipment，No carelessness is allowed in all aspects.。Since this Malani.MACSince 320 entered the Jiuma Expressway Project，Maleny keeps in close touch with his clients.，Always pay attention to the project dynamics，Additive vaporization during project application、Viscosity and the like，Jointly innovate with customers Sichuan Jiaotong Construction Intelligent Equipment Branch，It has been upgraded，An intelligent system for adding asphalt additives is developed.。

As the project site is located in a cold climate,、Under the special natural conditions of high altitude，When the additive is added，High temperature asphalt is encountered，Instantaneous vaporization often occurs.，And produce a large amount of flue gas.，It is not conducive to the safety and health of field workers.。
In order to effectively solve this problem，At the same time, it is also for more accurate measurement and addition of additives.，Marini at the request of the client，According to the actual situation on site，Set up a team with Sichuan Jiaotong Intelligent Equipment Branch，Joint research and development。

Through the joint efforts of both sides，An intelligent system for adding asphalt additives is developed.。This system can accurately measure additives.，The addition of three additive can be realized：Anti-stripping agent，Warm mix additive，Flame retardant。

Due to the high altitude of Jiuma Expressway, the natural conditions of cold and low temperature are caused.，Additives are prone to sticky problems.，The team used heat transfer oil heating and electric heating to heat the additives.，Ffectively ensure the fluidity of the additive，Is beneficial to the metering of the additive。

After the intelligent asphalt additive adding system is installed in the equipment,，During the adding process，Start of asphalt discharge，The operator selects the asphalt type on the operation interface.、Recipe，Just click Add。Add value according to the set additive，It can be divided into batches，Adopt the method of adding 5 tons at a time，Uarantees the even stirring of the additive，Meanwhile, the stirring time is saved.。There is only manual asphalt unloading in the whole process.，The rest is done automatically by the system.，And human resource are effectively saved.，Moreover, the asphalt Truck driver can complete the operation alone.。

Since Malani entered the Chinese market,，Always work together with customers，Committed to achieving the goal of providing the best Asphalt Mixing Plant for every customer。At present，With the continuous development of asphalt mixing equipment market,，Customer demand changes and upgrades are also accelerating.，Especially in the digital age.，The integration of hardware and software accelerates the demand for product iteration and upgrading.。At the same time，“Double Carbon” In the background，Enterprises are also facing digital transformation.、Energy transformation、Intelligent upgrade、Multiple challenges such as high-quality development。Under this trend，Marini uses an agile innovation mechanism.，So as to be more accurate、Meet customer needs more effectively。
