Raw material processing The raw materials such as silicate cement, lightweight aggregates (such as fly ash and coal gangue), coarse and fine sands, and plastic fibers are pre-treated through processes including drying, mixing and heating to ensure the quality and fluidity of the raw materials. Extrusion molding The pre-treated raw materials are extruded through the extruder under high pressure, forming sheets with different cross-sectional shapes at the die opening. This process requires the removal of internal air through a vacuum exhaust system to ensure the dense structure of the sheets. Maintenance and hardening The extruded sheets need to undergo high-temperature and high-pressure steam curing to further enhance their physical properties. For instance, a 60mm thick sheet must be maintained at a certain humidity and temperature in the curing system to ensure that its flexural strength reaches above 17.6 MPa. Cutting and Packaging After the maintenance is completed, the panels are processed into the required sizes by the cutting equipment, and then packaged for transportation and construction. Construction process   Dry construction: Fixed using large-head twist-lock screws. For indoor construction, leave a 3mm gap at the connection points of the panels, and 5mm for outdoor ones.   Hybrid construction: Install the reinforcing cross-columns first, then lock the screws for fixation. The screw spacing is 10cm.   Exterior wall construction: Use a galvanized framework with a thickness of 1.2mm or more as the support. First, stick the anti-clamping board, then install the cement board.   The ECP boards produced by this process possess features such as high strength, good weather resistance and light weight. They are suitable for applications in building facades, partitions, and other scenarios.  

The equipment is mainly suitable for the block, porous brick and wall panel with the maximum hole rate, and can also take into account the extrusion molding of solid brick. The maximum width of mud extrusion can reach 1700mm, suitable for raw materials, clay, shale, coal gangue and other raw materials. The main structural properties： 1.Two-body combination models are equipped with an exhaust system in which the upper mixer is connected to the lower extruder by a vacuum chamber 2.The upper mixer and the lower extruder are placed vertically 3.It can increase the effective area of the exhaust screen, improve the vacuum degree, and ensure that the raw material is not left in the vacuum chamber 4.The upper mixer is connected with the lower extruder through the vacuum chamber and has the following advantages: (1)The correct parallel feeding to the extruder screw shaft is guaranteed and its effective length is guaranteed (2)This reduces the rotational speed of the extruder, thereby reducing energy consumption and wear (3)More uniform thrust applied to the material (4)Ensure that raw materials do not remain in the vacuum chamber 5.Mixers and extruders are driven by individually configured gearboxes, and each operating unit is operated by pneumatic clutch 6.he equipment is all made of steel, with the best robustness and reliability 7.pulley equipped with rim for V-bel 8.When the equipment is running, the vacuum degree can be guaranteed to be more than 95% 9.Due to the good structure and the guarantee of the performance of each part, the extrusion pressure of the equipment can reach 3.5Mpa

This equipment was developed after our company signed a long-term cooperation agreement with Italian BOSTICCO company in 2017. BOSTICCO sent Italian technical director to provide technical services for our company for a long time. Meanwhile, in 2018, we jointly developed the most advanced super fine crushing roller machine in China. After the test, the fineness of the roller grinding can reach 0.5mm, which solves the problem that the fineness of the roller can not meet the use requirements in China. The technology is currently the most advanced of its kind in Europe. The company will continue to strive to create a design, manufacturing, research and development and business services as one of the international professional complete sets of building materials equipment manufacturing enterprises. By introducing and absorbing advanced experience from Italy and Germany, we fully adopt the current European manufacturing technology and process technology in complete sets of equipment, and have more than 100 experienced Chinese and Italian chief engineers, process personnel and project managers, relying on Italy, Germany and other foreign mature manufacturing technology and quality assurance system. The company will research and develop products in the domestic market sThis equipment was developed after our company signed a long-term cooperation agreement with Italian BOSTICCO company in 2017.
