Phenolic insulation board construction technical quality acceptance standards

by:Ventech     2020-12-28
1 construction quality acceptance shall be in accordance with the current national standard 'building energy conservation engineering construction quality acceptance standard' ( GB50411 - 2007). Carry on.
2, exterior insulation construction should be dealt with at the grassroots, phenolic insulation board, anchor gages fixed, paving glass fibres and wall thermal bridge site processing, etc.
3, each project of the amount of inspection shall meet the following requirements: a batch of inspection should be divided into per 500000 g, a group of less than 500 should be divided into a test batch; Every check each batch of 100 cases of at least a point, every batch of not less than 10, each batch of at least five.
4, the construction quality of the coating layer should comply with the 'building decoration and decoration engineering quality acceptance specification' GB50210 relevant provisions.
5, phenolic board and wall body should be strong, no loosening and virtual sticky. Bonded area shall not be less than 50% of the area of the plate. Methods: the JG149 - 2003 method, under the condition of dry, observing, testing the tensile strength of the phenolic plate and the bottom; Check the concealed engineering acceptance records.
6, the anchoring piece number, anchorage position, the anchoring depth, and drawing force shall meet the design requirements. Phenolic insulation board production convenient, can according to user needs in site construction; Cleaning and hygiene; Using aluminum foil composite sandwich board surface, ensuring the health of air from the duct, the frictional resistance is small, the air quality is high, because the product is called environmental duct. Because the product is made up of aluminum foil ﹢ phenolic foam ﹢ aluminum foil, and therefore has a good sound insulation, vibration resistance dimming and flame retardant, energy-saving features, to reduce the operation cost. The anchoring force field test method of tensile test: observation; Unloading anchor, measuring the anchoring depth; Caliper. Do the scene drawing test, check the test report. Phenolic plate thickness should meet the design requirements of
7, plus or minus deviation of 1. 5mm。 Test method: with steel needle insertion, check with your ruler.
8, phenolic plate surface coating interface agent, uniform interface agent, no lumps. Phenolic insulation board production convenient, can according to user needs in site construction; Cleaning and hygiene; Using aluminum foil composite sandwich board surface, ensuring the health of air from the duct, the frictional resistance is small, the air quality is high, because the product is called environmental duct. Because the product is made up of aluminum foil ﹢ phenolic foam ﹢ aluminum foil, and therefore has a good sound insulation, vibration resistance dimming and flame retardant, energy-saving features, to reduce the operation cost. Inspection method: to observe the; Check the concealed engineering acceptance records.
9, paste slurry and phenolic plate must be firmly together, no delamination, empty barrels, no explosion ash and crack defects such as surface. Phenolic insulation board with phenolic resin and flame retardant and smoke suppression agent, curing agent, foaming agent, and other additives, and other material, through scientific formula of closed groove rigid foam, phenolic insulation board in the areas of application: due to the flammable polystyrene foam and polyurethane foam, not high temperature resistant, Chiang kai-shek in some industrial developed country restrictions on use by the fire department, strict in fire protection, government departments have clear stipulation can only use phenolic insulation board. Therefore, phenolic foam material is more suitable for have strict requirements under the environmental conditions of use of high-performance materials, has a good development prospect. Test method: to observe; According to the JG149 - 2003 method for determining the tensile strength of mortar and phenolic plate, check construction record.
10, paste on the bottom surface of phenolic plate surface should meet the requirements of surface roughness. Inspection methods: observation and scale tests. In external wall thermal bridge
11, according to the design requirements, energy-saving insulation measures are taken to separate heat bridge. Inspection method: to observe the; Check the concealed engineering acceptance records.
12, the outer wall heat transfer coefficient should comply with the design documents and relevant specifications. Inspection method: inspect insulating sample test report in the same conditions. General engineering
13, phenolic plate installation should be up and down, close, sewing smooth, spliced joint shall not be erased. Inspection method: to observe the; Check construction record.
14, phenolic plate installation deviation should be allowed to meet regulations. Phenolic plate glass mat cloth of allowable deviation of installation and inspection method should strictly compaction, may not appear empty drum, folding, the phenomenon such as warp, exposure. Strengthening of reinforced net method should meet the design requirements. Inspection method: to observe the; Check construction record.
15, processing of deformation joint structure and the installation of the insulation slot, perforation, and decorative parts and fixed should meet the design requirements. Inspection method: to observe the; Hand to check.
16, outer wall plastering mortar layer allows deviation and inspection methods shall comply with regulations.
