How to prevent the glass curtain wall leakage and seepage problems

Curtain wall accessories expert analysis led to the curtain wall water seepage and leakage of the basic conditions of the three conditions: the existence of porosity; the presence of water; there is a water pressure cracks exist. So the treatment strategy: First, try to reduce the pores; Second, cover the rain, so as not to soak the gap; Third, to reduce the wetted gap at the wind pressure difference. Specific practices are as follows:

1, the design of the first consideration of the curtain wall waterproofing device design and construction, the use of isobaric principle, in the curtain wall aluminum plate is set on the pressure chamber and the special pressure into the hole, so that the pressure inside the pressure chamber through the introduction of special pressure and external pressure balance, The pressure difference to reach the indoor side of the rain, so there is no water pressure in the water there is no pressure and there is no water pressure, to prevent the use of external water pressure difference into the curtain wall, which is active waterproof measures.

2, in the curtain wall accessories on the opening of the aluminum flow to the outdoor drainage holes, through the small gap into the curtain wall of the internal collection of water outside the curtain wall, while row of glass, aluminum and aluminum buckle between the pressure chamber A small amount of water, which is one of the effective method of water control.

3, the design can also be considered in the glass curtain wall to set up the collection of pipes and drainage pipes, will penetrate the cracks into the curtain wall fittings within the water collected together, through the drainage pipe smoothly discharged to a designated indoor drainage hole, which is another Reliable water control measures.

4, the choice of high-quality structure of silicone sealant, weathering silicone sealant, wall glue, but also to strengthen the inspection to prevent expired use. Selection of high quality float glass, glass must be treated by the edge, glass size error in line with the standard requirements.

5, pay attention to control the use of sealant environment, is strictly prohibited rainy days for weathering silicone sealant construction. Structural plastic construction workshop requires clean dust, indoor temperature should not be higher than 27 ℃ (different brands of structural adhesive its performance is different from the indoor temperature requirements are slightly different), relative humidity should not be less than 50%.

6, the structure of silicone sealant, weathering silicone sealant, wall glue before injection, should first aluminum frame, glass or cracks on the dust, grease, loose and other dirt removed, Packing, surface formation, strengthen the conservation, to prevent hand touch, water red and so on.

7, according to the specification requirements, the glass curtain wall construction process should be layered anti-rain leakage performance inspection, in order to repair, the middle control curtain wall quality.
