    D finish layer is the construction process of the coating system
    Clean the dust on the base of the wall, dripping and oil stains, hanging the vertical wall of the exterior wall, the thickness control mark of the cloth surface, the screeding screed (this process can be omitted when the flatness and verticality of the wall meet the acceptance standards), spraying method Construction of polyurethane rigid foam insulation layer, brushing of polyurethane rigid foam interface layer, smoothing and roughing with plaster, and pressing in alkali-resistant glass fiber mesh cloth, batching of flexible exterior wall putty, spraying (brushing, roller coating) outside Wall elastic paint or spray imitation stone paint.
    Construction process of 2J facing layer for facing brick system
    Clean up the dust on the base surface of the wall, dripping and oil stains, hanging vertical lines on the wall, control signs of the thickness of the cloth surface, smoothing the screed (the process of wall flatness and verticality can meet this requirement), drilling Installation of special anchor bolts for construction of holes, construction of polyurethane rigid foam insulation layer by spraying method, brushing of polyurethane rigid foam interface layer, smoothing with rough surface glue, laying hot-dip galvanized steel wire mesh and firmly connecting with anchor bolts, smoothing with smooth surface glue Sweep hair, use special bonding material to paste external wall tiles, face brick flexible joints.
    3) Construction process of dry hanging stone or aluminum-plastic board
    Clean up the dust, dripping and oil stains on the base surface of the wall, leveling the squeegee (the flatness and verticality of the wall meet the acceptance standards), install the keel embedded parts on the load-bearing structure, spray the polyurethane hard Foam insulation layer, install the main keel on the keel embedded parts, hang the line on the outer wall according to the design layout and the size of the stone, install the secondary keel and the pendant on the main keel, open the groove on the stone, and use the pendant to fix the stone on the keel 2. Adjust the fastening nut of the pendant, and align the line to the size of the outer wall of the stone.
    The structural design of the exterior wall waterproof and thermal insulation system with the decorative layer of dry hanging stone is shown in Figure 3}
    Rigid polyurethane foam should be sprayed continuously at the corners (yin and yang corners) of the wall and at the interface of the base wall of different materials, as shown in Figure 4.
    4 spray hard foam polyurethane construction equipment
    Since the rigid foam polyurethane material is a two-component material, the curing speed is very fast, and it needs to be fully collided and mixed under a certain temperature and pressure to obtain good physical properties and effects. Therefore, the spraying construction equipment is very important in the application link. A set of standard rigid foam polyurethane construction equipment should be composed of four parts, namely the feed pump system, the host, the heating pipeline and the special polyurethane spray gun, see Figure 5};
