First, the rain and leakage prevention In the application process, color stone tile also appeared leakage, water seepage and other phenomena. The reason is related to the quality and construction quality of the colored stone tile produced by some manufacturers, and also has a great relationship with the tile structure of the colored stone tile.
Due to its wide size, thin thickness and easy breakage, the double-water grooved colored stone tile receives the same force as the single-water grooved colored stone tile. The torque received by the root of the double-water groove is a single-water groove. More than twice the probability that the color stone tile groove of the double water channel structure is destroyed is much larger. The construction personnel inevitably have to step on the surface of the tile. After the tile is covered, the water groove is invisible. Once it is broken, it is not necessarily found. This will cause water seepage and it is difficult to find the water seepage position. In addition, the color stone tile with double-water groove structure. Due to the production reasons, the ribs of the water groove are generally low, and some even exceed the groove bottom by less than 2mm. JC746-1999 requires that the height of the rib should not be low. At 3mm, it is difficult to achieve a good waterproof effect. Compared with the double-groove tile, the single-slot tile seam is opened at the highest point of the tile edge and the lap joint is tight and firm, the gap is small, forming an "S"-type joint, not afraid of wind, and the rain drops into the seam and enters The water groove has very little water and does not leak rain. The double-groove is not the case. Since the joint is opened at the half slope of the ridge, the water intake is 20-30 times that of the former, and it is easy to leak during heavy storms.
In addition to the structural form, the impermeability of the tile has a great influence on the leakage prevention. Tiles with lower density, high water permeability, continuous rain, some rainwater will penetrate the tile body, drip from the back, and penetrate into the house. The high-density tile, no matter how long the continuous rain and rain, the tile body will not seep, and the leak-proof function is reliable. Second, thermal insulation
Thermal insulation is one of the important functions of roofing envelopes. With the improvement of people's living standards, natural requirements for living conditions are higher, and residential comfort is one of the important indicators.
The thickness of the tile itself is limited, only 1cm, so it cannot be insulated. The heat insulation is completely sealed by the layer of air that is tightly sealed under the tile. The more sealed, the better the insulation. Just like the double-layer glass insulation, although there is only a thin layer of air between the two layers of glass, as long as the four sides are tightly sealed, the insulation effect will be good. If the four sides of the wind will not play any role.
The size of the tile is accurate, the lap joint structure is reasonable, and the tile is not warped. After it is set up, it is like a whole. It is tightly sealed. In addition to good rain and windproof, it naturally plays a good role in heat insulation. The double-slot tiles that have been eliminated are difficult to be spliced tightly, and the thermal insulation performance is bound to be bad. The insulation effect of the two will be 3 ° C to 4 ° C.
