Product characteristics
?
● This product is a green environmental protection product, non-toxic, tasteless, pollution-free. All of them meet the standard requirements of GB/T17219-1998 "Safety Evaluation Standard for Drinking Water transmission and distribution water equipment and protective materials".
?
● Due to the incorporation of anti-aging agents, the product has good anti-aging, anti-oxidation, anti-corrosion characteristics, good flexibility, easy to bend and not break, tensile and anti-perforation performance is good, in line with the standard requirements of GB18173.1-2012 "polymer waterproof material section", can be the same life as the building structure, polyethylene buried in the sand does not rot, do not weather, Through testing, it is proved that there is no crack at low temperature -40℃ and no deformation at high temperature +100℃.
?
● Can be constructed on the wet base, as long as there is no open water on the base can be constructed, after the heavy rain stops, the water can be cleaned immediately, which is conducive to the construction period.
?
● Good flexibility, easy to bend, arbitrary folding, easy to operate. Kitchen and bathroom, swimming pool, pool waterproof, negative, positive Angle and pipe root position do not do splayed Angle and arc, can be made into right Angle construction, to avoid the next process tile is picked waterproof coil phenomenon, to ensure that the second closed water does not leak.
?
● Fast construction speed and high efficiency. Kitchen, swimming pool, pool wall does not need to do hair or interface treatment, directly paste tiles on the coil, that is, save labor and effort.
?
● The polymer cement binder used in conjunction with the coil is a green environmental protection product. The main raw material is the matching glue and cement produced by the company into a paste, the binder is not only good bonding performance, but also itself is a waterproof layer, which can close the base wool seam holes, play a role in water blocking, the base requirements are very loose, and can play a leveling role.
?
● Strong puncture resistance, suitable for all kinds of green planting surface waterproof, anti-perforation performance is good, can play a role in preventing root thorns, waterproof effect is very obvious.
?

Construction method
?
● Construction procedure: acceptance screed → cleaning base → Preparation of cement adhesive → Additional layer → base construction → protective layer → maintenance
?
● Before bonding, first roll out the coil, find the right, and then fold the two ends of the coil in half, pour the prepared cement adhesive into the base, and then push the coil forward and use the scraper to exclude the air inside the coil in time to scrape out the excess binder. The bond rate between the coil and the screed layer is ≥85%.
?
● Seam method:
?
(1) Roof waterproof joint construction: the steam insulation layer, waterproof layer and additional layer are bonded with cement adhesive and the width is 10cm. The joint of the additional layer and the waterproof layer should be staggered by more than 5cm.
?
(2) Basement waterproof joint construction: The use of 10-15cm lapping cover seam, cover use polymer bonding adhesive bonding.
?
(3) Waterproof coil lap width long side 8-10cm short side 10-15cm, adjacent short side joints should be staggered more than 10cm between the wall and the ground Angle are more than 30cm.
?
● Protective layer:
?
After the winding material is laid and bonded, it is necessary to make a 1:2.5 cement mortar protective layer with a thickness of 2cm on the waterproof layer, and spread it twice. The two layer must be staggered by more than 20cm, and the protective layer shall be smooth and watered for maintenance.
?
Product application technology
?
When the polymer polyethylene propylene (polyester) nylon waterproof coil is bonded to the main body, the special supporting cement material is added as the adhesive.
?
● Building Application 1
?
Roof waterproof: The application should pay special attention to the bonding area and bonding strength of the coil and the screed layer, which is the key technology to ensure the waterproof effect and ensure the waterproof life.
?
Underground waterproof: the coil should be designed to be used under the conditions of water pressure and backing to prevent stripping. When used without backing, the stripping strength of the coil should be calculated.
?
Indoor impermeability: When applied to the internal wall including the floor impermeability, after the coil is pasted, the adhesive layer should be guaranteed to harden before surface decoration construction. Before the decorative surface of the interior wall, a layer of cement paste containing 1.5% polyvinyl propylene (polyester) fiber should be brushed on the coil material.
?
Ground moisture: applied to ground moisture, pay attention to the thickness of the ground surface layer to ensure the stability of the ground. The vertical height of the coil at the foot of the wall is not less than 200mm.
?
Heat insulation and gas insulation: single-sided composite coil can be used for steam insulation layer, and its paste and laying are the same as roof waterproof, and the joint is made of double-sided composite coil pad without protective layer.
?
● Building application of two channels, reservoir seepage prevention; Earth-rock dam seepage prevention
?
● Other applications can be used in metallurgy, chemical pollution prevention, seepage prevention, pipeline waterproof, mine waterproof, road and bridge waterproof, tunnel waterproof and other purposes.
