Material selection
? Thermal material selection board as composite insulation External formwork insulation layer material. The thermal conductivity of the board is small, the compressive strength and impact resistance are high, the water absorption rate is low, and the aging resistance is excellent. It is currently a better lightweight insulation material.
Ordinary Portland cement is selected as the cementing material as the main cementing material for bonding the reinforcing layer, the bonding layer, the insulation transition layer and the reinforcing ribs. Ordinary Portland cement has wide sources, low price, good water resistance, high strength and excellent durability.
The insulation board aggregate produced by the demolition-free building exterior formwork equipment selects artificial sand and natural sand mixed in a certain proportion as the bonding reinforcement layer, the bonding layer, the insulation transition layer and the sand for reinforcing ribs.
Vitrified microspheres are selected as the lightweight filling material for the thermal insulation transition layer.
The powder is selected from the type of rubber powder produced by the German Wacker Company to improve the bonding strength, water resistance and other properties of the polymer mortar.
Additives In order to effectively improve the physical and mechanical properties of each layer of composite insulation, water-reducing agents, waterproofing agents, polymers and other additives are also added.
Alkali-resistant glass fiber mesh is selected and laid on both sides of the composite insulation formwork to improve its impact resistance, bending load and other mechanical strength.
Production process and equipment
Preparation process of equipment for dismantling building exterior formwork
Preparation of cement dry powder mortar, cementitious materials, aggregate rubber powder and other raw materials are measured, mixed and stored.
Warm mortar dry powder is used to prepare gelling materials, vitrified microbeads, rubber powder and other raw materials. The raw materials are measured, mixed, stirred, and stored. The preparation process of the composite thermal insulation formwork mainly includes cutting the extruded board, creating grooves, spraying interface agent, laying the inner bonding reinforcement layer of the insulation, and curing the bonding layer, laying the reinforcement layer on the outside of the insulation board, the insulation transition layer and the outer bonding reinforcement. Layer, natural maintenance day after leaving the factory.
The exterior formwork equipment of the building without dismantling is mainly composed of electronic metering device, dry powder mortar mixer, slurry mixer, work lifting frame, smoothing device, transmission equipment and cutting machine. Dry powder mortar mixer The slurry mixer adopts automatic batching and electronic metering, with a high degree of automation and accurate metering. The molding equipment has the characteristics of reasonable structural design, convenient production and operation, short molding cycle, high production efficiency, high product quality, etc.
Product standards and performance index testing are based on our province’s current “Residential Building Energy Saving Design Standards” and the national “Construction Formwork Safety Technical Specifications” and integrated technical requirements, and the enterprise standard “Composite Exterior Formwork Cast-in-Situ Concrete Insulation Structure System” was formulated. 》. After testing by the Shandong Provincial Construction Engineering Quality Supervision, Inspection and Testing Center, the mechanical performance indicators and weather resistance of the permanent composite thermal insulation exterior formwork and composite exterior formwork insulation system all meet the requirements of relevant national standards and corporate standards
