Thermal Insulation Sandwich Panel Production Equipment
Insulated sandwich panels as a building material that integrates thermal insulation, structural functionality, and waterproof performance, are widely used in the field of modern architecture. The technical level of its production equipment directly determines product quality and production efficiency.
According to the different core materials and production processes, insulation sandwich panel production equipment can be divided into the following categories:
Cement foam insulation board equipment
The cement foam insulation board equipment is a key equipment for producing A1 grade fireproof insulation materials, mainly using ordinary Portland cement and fly ash as raw materials. This type of equipment typically includes fully automatic feeding systems, mixing systems, pouring foaming systems, cutting systems, and packaging systems. The product has the characteristics of fire prevention, environmental protection, insulation and energy saving, and is widely used in the fields of building exterior wall insulation, fire isolation belts, etc.Inorganic fiberglass insulation board equipment
The inorganic fiberglass insulation board equipment adopts a dual drive roller extrusion process, which can complete the entire board production process such as sizing, main material, laying, composite, and re pressing in one go. The equipment has a high degree of automation and can produce plates with thicknesses ranging from 0.2mm to 50mm, with a smooth and flat surface. Its notable feature is the ability to produce corrugated boards, which save on roof waterproofing costs through perfect wave overlap technology.Perlite insulation board equipment
The perlite insulation board equipment realizes fully automated production, from automatic feeding to automatic mixing, pressing, ejecting, conveying, and spraying in one go. The production efficiency is extremely high, with 2 boards produced every 15-20 seconds. The equipment adopts thickened steel and national standard accessories, and the mold is specially treated to prevent deformation, ensuring accurate product dimensions.Polyurethane sandwich panel equipment
Polyurethane sandwich panel equipment is mainly used for producing composite panels with an outer layer of fiberglass or oriented strand board and an inner layer of polyurethane board. A typical production line includes equipment such as cleaning machines, glue coating machines, billet assembly machines, cold or hot presses, and drum discharge machines. The boards produced by this type of equipment have excellent insulation, fire resistance, and thermal insulation properties, and are widely used in industrial plants, cold storage, and other fields.
The production processes of different types of insulation sandwich panels have their own characteristics, but they generally include the following key steps:
Raw material preparation and mixing
By using an automatic feeding system, raw materials such as cement, foaming agent, and foam stabilizer are added to the mixer in proportion for dry and wet mixing. The precise measurement system ensures that the error rate of raw material ratio is less than 2%.forming process
Foaming molding: Inject the mixed slurry into the mold for foaming, the process takes about 3-5 minutes (cement foam board)
Roll forming: Using dual drive roller extrusion technology, laying, compounding, and re pressing (inorganic fiberglass sheet) can be completed in one go
Compression molding: one-time molding through high-pressure molds (polyurethane sandwich panels)Maintenance and demolding
After the injection molding is completed, it needs to be left to stand for initial curing. After the board has initially set and reached initial strength, it can be demolded. The curing age of foam cement board is generally not less than 7 days.Cutting and processing
After demolding, the blank is adjusted in size according to the needs through an automatic cutting system, and the cutting accuracy can reach ± 0.5mm.post-processing
Including surface treatment, edging, packaging and other processes, some products require secondary curing to improve final strength.
Automatic insulation sandwich panel equipment generally adopts PLC control system to achieve automatic measurement, automatic feeding, automatic cutting and other functions, greatly reducing manual intervention and improving product consistency.
Key points for purchasing
Automation level: Prioritize fully automated production lines to reduce labor costs and improve stability
Production adaptability: Can the equipment adjust to produce boards of different thicknesses and lengths
Energy consumption indicators: Pay attention to the consumption of resources such as electricity and water
After sales service: supplier's technical support capability and spare parts supply situation
Environmental performance: whether the equipment has functions such as dust collection and wastewater treatment
The products produced by insulation sandwich panel equipment are widely used in:
Thermal insulation engineering for building envelope walls
Internal and external walls of steel structure buildings
firebreak
Roof insulation system
Cold storage construction
mobile home
Fireproof door core board
The technological progress of insulation sandwich panel production equipment is driving the development of the building insulation material industry towards high efficiency, energy conservation, and environmental protection. With the continuous improvement of national requirements for building energy efficiency, the market prospects for high-performance insulation sandwich panels and their production equipment are broad. When selecting equipment, enterprises should comprehensively consider their product positioning, market demand, and equipment performance, and choose the most suitable production solution.
