sandwich panel line
Different from ordinary rock wool board production line for industrial insulation and exterior wall decoration, this targeted production line fully considers the special application needs of activity rooms. Most activity room buildings are assembled with light steel structures, which puts forward higher requirements for the matching performance of supporting plates: the plates need to have moderate thickness, stable dimensional tolerance, lightweight texture to reduce the overall load of the light steel frame, while maintaining excellent fire prevention and heat preservation functions to adapt to complex outdoor environments such as high temperature, low temperature and strong wind. Moreover, activity rooms are densely populated in most usage scenarios, so the fire safety level of the plates is the primary evaluation index. The production line adjusts raw material ratio, fiber forming process and curing molding parameters throughout the whole process to eliminate flammable components in the products, ensure that the finished boards have non-combustible characteristics, and effectively block the spread of open fire and heat flow, providing reliable safety barriers for prefabricated buildings.
The whole production process of the fireproof rock wool sandwich panel production line for activity rooms is carried out in a continuous closed cycle, covering raw material pretreatment, high-temperature melting and fiber forming, binder spraying and fiber lapping, constant-temperature curing and shaping, cooling setting, precise cutting and finished product stacking, with each process closely linked and precisely controlled by an integrated electromechanical system. In the raw material pretreatment stage, natural inorganic mineral raw materials such as basalt and dolomite are selected as the core substrates, which are inherently non-flammable and high-temperature resistant, laying a fundamental foundation for the fire resistance of finished products. These bulk raw materials are first crushed into uniform fine particles by professional crushing equipment, and impurities such as soil and sundries mixed in the raw materials are removed through vibrating screening equipment to ensure the purity of the raw materials. Subsequently, multiple raw materials are proportioned through an automatic electronic metering system, and auxiliary materials are added in a scientific ratio to adjust the fiber toughness and structural compactness of subsequent products. The fully mixed raw materials are transported to the sealed storage silo through a closed conveying system, which avoids material pollution and dust overflow, and ensures the stability and consistency of raw material components for each batch of production.
High-temperature melting and fiber forming is the core process that determines the basic performance of rock wool boards, and it is also the key link to realize the excellent fire resistance of activity room special plates. The uniformly mixed mineral raw materials are automatically sent to the high-temperature melting furnace through the feeding system, and the furnace is equipped with a high-temperature resistant refractory lining structure, which can stably maintain a high temperature environment between 1400 and 1600 degrees Celsius. Under the action of continuous high temperature, the solid mineral particles are completely melted into uniform and viscous magma liquid, eliminating all organic flammable substances in the raw materials. After full melting and homogenization, the magma flows steadily into the high-speed centrifugal fiber forming system. The high-speed rotating centrifugal equipment stretches and throws the magma into ultra-fine inorganic fibers under the action of centrifugal force and high-speed air flow. The fiber fineness and length are automatically adjusted according to the production parameters set for activity room plates, forming slender and uniform fiber filaments. This fine and dense fiber structure can not only enhance the fire resistance of the plate, but also form a large number of tiny closed air gaps inside the plate, endowing the product with good thermal insulation and sound insulation effects, which can effectively isolate outdoor temperature changes and reduce indoor and outdoor heat exchange for activity rooms.
In the continuous fiber forming process, quantitative environmental-friendly inorganic binders are evenly sprayed on the surface of rock wool fibers through a high-pressure atomization spraying system. Different from traditional organic binders that are easy to burn and release harmful substances, the binders used in this sandwich panel production line have high temperature resistance and non-combustible properties, which will not reduce the fire safety level of the finished plates. The atomized binder can be fully attached to the surface of each fiber filament, realizing uniform bonding between fibers, avoiding local loose structure of the plates, and improving the overall structural strength and shape stability of the rock wool board. The fiber filaments sprayed with binders are uniformly laid into continuous fiber wool mats through a pendulum lapping system. The pendulum lapping equipment adopts reciprocating layered laying technology, which can make the fibers cross and stack in multiple directions, effectively solving the problem of uneven density and inconsistent thickness of traditional single-layer laid wool mats. The layered fiber structure enables the finished rock wool board to have uniform stress performance in all directions, not easy to deform and crack during cutting, assembly and long-term use, and can better adapt to the frequent handling and assembly characteristics of mobile activity room buildings.
The uncured fiber wool mat enters the pre-pressing device first, and the loose fiber mat is initially compressed and shaped through controllable mechanical pressure to discharge excess air inside the fiber layer and preliminarily fix the overall thickness and width of the plate. The pre-pressed wool mat is more compact in structure, which facilitates subsequent high-temperature curing and improves the flatness of the finished product. Then the wool mat is sent to the constant-temperature curing oven for high-temperature curing treatment. The curing oven is equipped with a precise temperature and air circulation regulation system, which can form a uniform hot air environment inside the equipment. Under the action of continuous constant temperature and hot air circulation, the moisture in the fiber mat is completely evaporated, and the binder undergoes stable curing and cross-linking reaction, so that the scattered fibers are firmly bonded into an integral rigid plate structure. The curing temperature and running speed are dynamically adjusted according to the set density and thickness standards of activity room special plates, ensuring that each batch of plates achieves consistent curing effect, stable internal structure and no loose or hollow phenomena. This curing process greatly improves the mechanical strength and structural stability of the rock wool board, enabling the plate to resist external pressure and impact during use, and maintain intact performance in long-term outdoor open-air environment.
After completing the high-temperature curing process, the high-temperature rock wool board is transported to the automatic cooling section for natural cooling and shaping. The cooling section adopts circulating air cooling without forced rapid cooling, which avoids structural cracks and performance attenuation caused by rapid temperature change of high-temperature plates. Through gradual and uniform cooling, the internal stress of the plate is completely released, and the plate size and structure are completely stabilized, ensuring that the finished product has good flatness and dimensional stability, and will not warp or deform after long-term use. The cooled rock wool board has formed a complete rigid plate structure, with stable fire resistance, thermal insulation and mechanical properties, and then enters the precise cutting and finishing process. The rockwool sandwich panel production line is equipped with an automatic fixed-length cutting system, which can intelligently adjust the cutting size according to the common specification standards of activity room enclosure plates. The high-precision cutting equipment ensures smooth and neat plate sections without burrs and edge cracks, which is convenient for rapid assembly and splicing of activity rooms on site, reducing on-site processing procedures and improving the construction efficiency of prefabricated buildings.
The finished rock wool boards after cutting and inspection are automatically stacked and sorted by the mechanical stacking system, and the whole production process is completed by matching with the dust removal and cleaning system. The whole rock wool sandwich panel line realizes closed automatic operation from raw material feeding to finished product output, with high production continuity and low manual intervention, which effectively reduces the error rate caused by manual operation and ensures the stable and reliable quality of each finished plate. In terms of equipment performance optimization, the production line is equipped with a waste heat recovery system, which recycles and reuses the waste heat generated by high-temperature melting and curing, reducing energy loss in the production process, realizing energy saving and low-consumption production, and conforming to the green and environmental protection development concept of modern construction materials.
The rock wool boards produced by this professional production line are highly matched with the actual use needs of activity rooms in performance and structural characteristics. In terms of fire resistance, the all-inorganic raw material formula and high-temperature fiber forming process make the plate have excellent non-combustible performance, which can effectively resist high temperature flame baking, prevent flame spread and heat conduction, and can maintain structural integrity in a certain period of fire environment, winning valuable escape and rescue time for personnel in the activity room. In terms of thermal insulation performance, the dense ultra-fine fiber internal structure forms a stable heat insulation layer, which can effectively isolate outdoor high temperature in summer and reduce indoor heat loss in winter, significantly improving the indoor comfort of temporary activity rooms and reducing the energy consumption of indoor temperature regulation equipment. In terms of sound absorption and noise reduction, a large number of micro-pore structures inside the plate can absorb and isolate outdoor noise, creating a quiet indoor environment for office, accommodation and other scenarios of activity rooms.
In addition, the product has excellent moisture resistance and weather resistance. After special curing and shaping treatment, the internal structure of the plate is compact and stable, which is not easy to absorb moisture and deliquesce in humid outdoor environment, and will not cause performance degradation such as reduced fire resistance and loose structure due to moisture absorption. It can adapt to the alternating environment of wind, sun and rain in outdoor open-air places, and maintain stable comprehensive performance in long-term use. At the same time, the lightweight design of the plate reduces the self-weight of the activity room building, reduces the bearing pressure of the light steel foundation frame, improves the overall structural safety of the prefabricated building, and also facilitates the transportation, handling and secondary disassembly and reuse of activity room plates, meeting the flexible use characteristics of temporary buildings.
