Aluminum-plastic plate roof is similar to the shape of many store signs, but the area is much larger times, like a box of the same, the middle of the keel or something, the other few are aluminum-plastic panels, combined into a cube. The most intuitive understanding of the container, or sealed the top of the truck compartment, surrounded by closed but the middle of the gap, so although the indoor water leakage point is fixed, and perhaps can not explain that only these leaks leak, there may be other places leaking , Because some points are low or just the seams are so leaked from these points. From this point of view, I do not know whether the need to clean up all the previous waterproof ointment, all re-silica gel?
No, with glass glue can get, the cost of tens of dollars and to.
Aluminum plastic plate waterproofing You should pay attention to the aluminum surface is relatively smooth, waterproof glue must choose a little bigger viscosity, so as to seize the smooth aluminum, cracks, how wide, if more than 5mm will use non-woven fabrics to support the plastic , That is, first coated with a layer of non-woven layer of adhesive and then coated with a layer of glue, the first layer to be wider than the leakage 3 - 5cm. More economical waterproof ointment can solve the problem, the use of the adhesive surface must be kept clean, no water, sticky coating to choose the sunny afternoon high temperature period, so that the best use of waterproof ointment viscosity. There is no hole in the aluminum-plastic plate, where the seam is not leaking, and only fill the hole at the sewn.
You do not talk about how fast cracks, a total of how long, that is, if a tube of glass glue enough you can consider using (that is, sticky fish tank that kind of glue) and winter is not suitable for waterproof work, And thermal expansion and contraction are problematic. Another cost of plastic should also be considered.
