12、 plan,And technical disclosure. The roof waterproof project must be certificated by the professional construction team.2.3.2 paving waterproof layer of the base must be completed construction, and after maintenance and drying, waterproof layer should be cleared before the construction of grass-roots
13、 surface, and at the same time grass-roots acceptance, qualified before the construction of waterproof layer.2.3.3 grass slope should meet the design requirements, no hollowing, cracking, sanding, peeling and other defects; the moisture content should be less than 9%.2.3.4 waterproof layer construct
14、ion, according to the design requirements, ready to coil and supporting materials, storage and operation should be far from the fire source, to prevent accidents.3.1 process:Base cleaning; brushing the base treatment agent; adding additional layer construction; coating the surface of the coil and th
15、e base layerThe laying of materials, winding head, bonding, sealing of coil joint, storage of water test, protection layer3.2, clean the grassroots: Construction of waterproof layer before the acceptance of the grass-roots surface cleaning. Dust, debris and other defects affecting the quality of wat
16、erproof layer shall not be allowed.3.3 brushing base treatment agent: coating polyurethane bottom adhesive.Preparation of 3.3.1 adhesive polyurethane outsole: polyurethane material according to a: B =1: 3 (weight ratio) ratio, stirring evenly coated by polyurethane material construction; also can ac
17、cording to a: B: xylene =1: 1.5: 1.5 ratio, stirring and coating construction.3.3.2 polyurethane adhesive coating: large area coating, paint brush bottom glue in the corner, Guan Gen and outfall details such as complex parts evenly over polyurethane adhesive. Then use a long roll brush to brush in a
18、 large area. Xu brush bottom rubber (equivalent to cold base oil), thickness should be consistent, shall not have brush, gray and other phenomena.The 3.4 part: the construction of additional layers of yin and Yang, Guan Gen and outfall must first do an additional layer, using self adhesive or sealan
19、t polyurethane coating, can also be paving a layer of synthetic polymer waterproofing materials. Should be determined according to the design requirements.3.5 coil and base wheat surface coating:3.5.1 coil surface coating: the coil spread on a clean base, with long rolling brush dipped in CX-404 rub
20、ber, roll evenly. Should be left to overlap parts, not glue, and the edge of the head vacated 100mm.The adhesive coating thickness should be uniform, there shall be no leakage or condensation of substances; membrane gelatinize 10 20min after static drying, when the finger is not sticky, raw material
21、 barrel will glue surface outward rolled up, flat head end roll, roll stiffness, diameter should not be a big head, a head small, and to avoid getting involved in the sand and debris, keep clean.3.5.2 surface is coated with adhesive glue: after drying, the surface coating of CX-404 glue, with long b
22、rush dipped in CX-404 glue, not in a repeated brushing, prevent the formation of sticky glue or since the end of condensation, the detail position can brush evenly, static dry paving material.3.6 coil laying: coil and base have been coated with glue, basically dry (hand touch non stick, general 20mi
23、n or so), you can do paving, coil construction. The number of plies and thickness of the coil shall comply with the design requirements.3.6.1 membrane should be parallel to the roof from the eaves covered slope, two-way flow sheet lap should shun the direction of the water flow, lap width long side
24、and end, such as empty shop, sticky, sticky, are 100mm; fully adhered method was 80mm, and the end of Jiecha to stagger 250mm.3.6.2 coil should start from the downhill slope of water flow, release the datum line according to the specifications of the coil, and make the length of the coil perpendicul
25、ar to the water slope. Attention should be paid to coil preparation to reduce the joints at the angle of yin and yang.Shop 3.6.3 coil connected paste plane and facade, from down to up, make the material close to the corner, on the web is not spreading can be pulled too tight, and there shall be no w
26、rinkles and hollowing phenomenon.3.6.4 venting and compacting 3.6.4.1 exhaust: every time after laying a roll of coiled material, should immediately clean and soft long roll brush from the end of the coil, roll toward the coil in the transverse order, to remove the air between the coil bonding layer
