In terms of technical development of glass fiber cloth, this complete set of technology pursues innovation, enriches and develops traditional external thermal insulation technology:
(1) ZL cast-in-place non-network polystyrene board polystyrene particle external insulation technology, its development of traditional technology is mainly manifested in the following five aspects:
①Research and development of polystyrene board with dovetail groove, which improves the bite force between polystyrene board and concrete wall when pouring concrete walls.
②Research and development of ZL polystyrene board coating interface agent. Before the polystyrene board leaves the factory, use ZL polystyrene board to brush the interface agent to carry out interface treatment on both sides of the polystyrene board. The purpose of the inner surface treatment is to further improve the bonding ability of the polystyrene board and the concrete wall; the outer surface treatment is mainly to prevent the surface layer of the polystyrene board from being pulverized after being exposed to sunlight (the thickness of the powdered layer is about 1.5mm per year) and the outer surface of the polystyrene board is damaged. Slurry pollution, etc. )
③In the process of on-site combined pouring, the use of ABS engineering plastic staples can effectively control the smoothness of pouring and prevent the occurrence of grout, avoiding the occurrence of "hot bridge" and "cold bridge".
④ Use ZL rubber powder polystyrene particle insulation slurry to repair and level the surface of the polystyrene board, fill the screw holes through the wall, and solve the problem that the surface flatness of the polystyrene board and the verticality of the corners of the polystyrene board and the corner of the balcony cannot meet the acceptance standards, which is effective The local thermal bridges such as the sides of the door and window openings, the seams of the boards, the thinned parts of the polystyrene boards, and the screw holes through the walls are effectively eliminated.
⑤ Utilize the flexible structure of the thermal insulation system to effectively solve technical problems such as cracks on the thermal insulation wall
(2) ZL cast-in-place mesh polystyrene board polystyrene particle external insulation technology. Its development of traditional technology is mainly manifested in the following three aspects:
① After smoothing and covering the exposed steel wire mesh of the polystyrene core board with ZL rubber powder polystyrene particle slurry, the heat flow loss of the obliquely inserted steel wire penetrating the polystyrene board is solved, and the heat preservation effect is improved;
②The external thermal insulation and anti-crack protection layer follows the technical route of flexible gradual change. When the finish is paint, use ZL rubber powder polystyrene particle thermal insulation slurry to smooth the steel wire mesh. The method of ZL cement anti-cracking mortar compounded with alkali-resistant mesh cloth (when the facing is brick, use ZL rubber powder polystyrene particle insulation slurry to smooth the steel wire mesh, and ZL cement anti-cracking mortar compounded with galvanized quadrangular mesh), replacing The method of smoothing the steel wire mesh with raw cement mortar, which is easy to cause cracks in the surface layer, solves the technical problem that the surface layer is prone to cracks;
③Compared with cement mortar, the thermal insulation system adopts ZL rubber powder polystyrene particle thermal insulation slurry, which reduces the load by about 50kg per square meter and buffers its ability to resist earthquake destructive force.
1.2.4 In terms of hanging technology verification, the reliability of this complete set of technology has been fully demonstrated, and it is currently the only system in China that has passed the European Community standard for temperature, humidity and earthquake resistance. Proven technology for large-scale tests such as wind pressure resistance and fire reactivity. The complete set of technology has passed nearly 500 inspections and certifications by many national authoritative inspection agencies in all application provinces, municipalities, and autonomous regions. The inspection contents include: thermal insulation performance, fire protection and thermal radiation performance, temperature difference resistance, impact resistance The performance of the thermal insulation system such as aging resistance and various performance indicators of different materials in the thermal insulation system, and conducted several on-site sampling tests on the completed projects. The inspection results show that all material performance indicators and system performance indicators of the complete set of technology meet the specified requirements, which better proves the reliability and practicability of the system.
