Rockwool sandwich panels, also known as stone wool sandwich panels, are composite panels composed of two layers of surface materials and a middle rockwool core. The surface materials are usually color steel plates, aluminum plates or other metal sheets with good corrosion resistance and decorative properties, while the core material is rockwool made of natural rock minerals such as basalt, diabase and dolomite through high-temperature melting, fiber drawing, curing and other processes. This special structure gives rockwool sandwich panels multiple excellent performances: it is non-combustible and has strong fire resistance, which can effectively delay the spread of fire in residential buildings and protect the life and property safety of residents; it has excellent thermal insulation performance, which can reduce the energy consumption of residential heating and air conditioning, help achieve the goal of energy conservation and emission reduction, and improve the living comfort of residents; at the same time, it has good sound insulation effect, which can isolate outdoor noise and indoor sound transmission, creating a quiet and comfortable living environment. In addition, rockwool sandwich panels are light in weight, high in strength, easy to install and long in service life, which can greatly shorten the construction period of residential buildings and reduce the overall construction cost. These advantages make rockwool sandwich panels widely used in exterior walls, interior partitions, roofs and other parts of residential buildings, especially in high-rise residential buildings, low-rise villas and affordable housing projects.

The rockwool sandwich panel production line is a continuous and automatic equipment system that integrates mechanical, electrical, hydraulic and chemical technologies, which can realize the whole process of rockwool sandwich panel production from raw material processing to finished product packaging. The working principle of the production line is to process the surface materials and rockwool core material through a series of coordinated processes such as uncoiling, forming, gluing, compounding, curing, cutting and stacking, so as to produce rockwool sandwich panels that meet the specifications and performance requirements of residential buildings. The production line is highly automated, which can minimize human intervention, ensure the stability and consistency of product quality, and greatly improve production efficiency. Compared with the traditional manual or semi-automatic production mode, the rockwool sandwich panel production line not only reduces the labor intensity of workers, but also reduces the waste of raw materials, realizing the economical and efficient production of rockwool sandwich panels.

The production process of the rockwool sandwich panel production line for residential buildings is a systematic and continuous process, which can be roughly divided into several key links: raw material preparation, surface material processing, rockwool core processing, compounding and curing, cutting and finishing, and packaging and storage. Each link is closely connected and mutually restricted, and the quality of each link directly affects the final performance and quality of the rockwool sandwich panel.

Raw material preparation is the foundation of the entire production process, and the quality of raw materials directly determines the performance of the finished rockwool sandwich panel. For the surface materials, it is necessary to select metal sheets with appropriate thickness and performance according to the use requirements of residential buildings. The surface of the metal sheets should be flat, free of scratches and corrosion, and have good adhesion to the adhesive. Before entering the production line, the metal sheets need to be inspected and cleaned to remove surface oil, dust and other impurities, so as to ensure the bonding effect between the surface material and the rockwool core. For the rockwool core material, natural rock minerals need to be selected as raw materials, and the raw materials should be crushed into uniform particles through crushing equipment, then sent to the melting furnace for high-temperature melting. The melting temperature is usually controlled at 1400-1600 degrees Celsius, so that the rock particles can be completely melted into a molten state. The molten rock liquid is then drawn into fine rockwool fibers through a fiber drawing machine, and the fibers are sprayed with a certain amount of binder and curing agent, and then formed into rockwool blankets or rockwool boards through a curing oven. The rockwool core material used in residential buildings needs to have appropriate density and thickness, so as to ensure its thermal insulation, fire resistance and sound insulation performance.

Surface material processing is the next key link, which mainly includes uncoiling, leveling and forming of metal sheets. The metal sheets are usually stored in the form of coils, and the uncoiling machine on the production line will uncoil the metal coils at a uniform speed. During the uncoiling process, the tension control device will adjust the tension of the metal sheet to ensure that the sheet is flat and does not wrinkle. After uncoiling, the metal sheet enters the leveling machine, which removes the internal stress of the sheet through the extrusion of multiple rollers, making the surface of the sheet flatter and improving the flatness of the finished panel. Then, according to the design requirements of residential building panels, the leveling metal sheet enters the forming machine, which bends and forms the sheet into the required shape through a series of forming rollers. The forming shape can be adjusted according to the needs, such as flat panels, corrugated panels, etc., to adapt to different parts of residential buildings such as exterior walls and roofs. The forming process needs to strictly control the forming speed and pressure to ensure that the shape of the surface material is accurate and the dimensional error is within the allowable range.

Rockwool core processing is mainly to cut the pre-made rockwool blankets or rockwool boards into the required size and thickness according to the specifications of the sandwich panel. The rockwool core cutting machine on the production line is equipped with a high-precision cutting blade, which can cut the rockwool core material into uniform size quickly and accurately. During the cutting process, it is necessary to control the cutting speed and cutting angle to avoid the rockwool fibers from falling off and affecting the quality of the core material. At the same time, the cut rockwool core material needs to be inspected to remove the unqualified products with uneven thickness, loose structure and other problems, so as to ensure that the rockwool core material entering the compounding link meets the quality requirements. In addition, in order to improve the bonding effect between the rockwool core and the surface material, the surface of the rockwool core can be treated with a primer, which can enhance the adhesion between the core material and the adhesive.

Compounding and curing is the core link of the entire production process, which realizes the combination of the surface material and the rockwool core material to form a complete rockwool sandwich panel. First, the surface material after forming is sent to the gluing machine, and the gluing machine sprays a uniform layer of adhesive on the inner surface of the surface material. The type and dosage of the adhesive need to be selected according to the material of the surface material and the rockwool core, so as to ensure that the bonding strength between the two meets the requirements. The adhesive should have good weather resistance, water resistance and high temperature resistance, so as to adapt to the different use environments of residential buildings. After gluing, the surface material and the cut rockwool core material are sent to the compounding machine together, and the compounding machine presses the surface material and the rockwool core material tightly through the pressure roller, so that the adhesive can fully contact with both, and realize the initial bonding. Then, the initially compounded sandwich panel enters the curing oven for curing treatment. The curing temperature and time need to be strictly controlled according to the type of adhesive and the thickness of the panel. Generally, the curing temperature is between 80-120 degrees Celsius, and the curing time is 20-60 minutes. During the curing process, the adhesive will gradually solidify, so that the surface material and the rockwool core material are firmly bonded together, forming a sandwich panel with stable structure and high strength. After curing, the sandwich panel will have good overall performance, which can meet the use requirements of residential buildings.

Cutting and finishing is to cut the cured continuous sandwich panel into the specified length according to the order requirements, and perform edge trimming and surface finishing. The cutting machine on the production line adopts a high-precision cutting system, which can realize non-stop cutting during the continuous production process, ensuring the cutting accuracy and efficiency. The cutting length can be adjusted freely according to the needs of residential building construction, which is flexible and convenient. After cutting, the edge of the sandwich panel may have burrs, unevenness and other problems, which need to be trimmed by the edge trimming machine to make the edge of the panel smooth and neat. At the same time, the surface of the sandwich panel is inspected, and the unqualified products with surface scratches, bonding defects and other problems are removed, so as to ensure the appearance quality of the finished product. In addition, some residential building projects may require the surface of the sandwich panel to be sprayed or coated, which can be completed in the finishing link to improve the decorative performance and corrosion resistance of the panel.

Packaging and storage is the final link of the production process, which is to package the qualified finished rockwool sandwich panels to avoid damage during transportation and storage. The packaging machine on the production line usually uses plastic film, foam cotton or carton for packaging, and the packaging should be tight and firm to prevent the panel from being damp, scratched or deformed. After packaging, the panels are stacked neatly in the warehouse according to the specifications and models, and the warehouse should be kept dry, ventilated and free from pollution. During storage, it is necessary to avoid stacking too high to prevent the panels from being crushed, and to separate different specifications and models to facilitate management and transportation. The packaged rockwool sandwich panels can be directly transported to the residential construction site for installation, which greatly improves the construction efficiency.
