Executive Standard

<<Thermoplastic Polyolefin (TPO) Waterproof Membrane >>GB27789-2011

Construction technology

* Base treatment: the base must be flat, dry, clean, free of empty drums, sand, cracking and so on. It must remove stagnant water, snow and ice so as to prevent the absorption of moisture in the part of the new roof and the layer system, and clean up the debris and foreign objects on the base before placing the coiled material.

* The mechanical fixation of the rolling stock in the lap area: to fix the coil with a fixed piece,the center spacing of the fixed parts is determined by the local wind speed, the type of the base of the mechanism, the height of the building and the width of the coiled material, and shouldn’t be greater than 600mm. The TPO rolls within the range of surrounding 800mm should be sticky full. Secondly, at each roof height change, side walls, skylights, deformed joints, all basic-level yin-yang angles with slopes greater than 1 / 6, as well as all pipes and pouring seal hoop grooves, all the materials are required to be firm.

  * Hot air welding: use automatic hot air welding machine or manual hot air welding machine as well as silicone rubber roll to hot air welding TPO coils. Where all joints intersect, use silicone rubber roller to ensure continuous seam of hot air weld. Surface irregularity caused by multilayer thickness of TPO coils may cause false welding

Matters need attention

* Seam welding parts must be clean, no dust, dirt, etc. If necessary, need to be scrubbed by solvent, otherwise it will affect bonding.

* The adhesives should be painted evenly, not exposed to the bottom, and not accumulated.

* Construction is strictly prohibited on rainy and snowy days and above the 5 grade gale. The temperature of the construction environment can’t be lower than 0℃.

* When precipitation occurs during construction, the protection of the coiled material should be done well.

 

 Application Range

It is widely used in waterproofing works of all kinds of roofs in common, civil and public

buildings.

Transport and storage

* The coil should be stored in a dry and ventilated environment, and protective measures should be taken to avoid sun and rain.

* During transportation, products of different types and specifications should be stacked in categories and can’t be mixed up; far from heat sources, no contact with acid, alkali, oil and organic solvents.

* During transport, it should be placed horizontal or vertical to prevent tilt, pressure and if necessary, cover with felt cloth.

* Storage temperature not exceeding 45℃, height of amplifier not exceeding 5 layers.

* Under normal storage and transportation conditions, the storage period is 12 months from the date of production. Once exceed the storage period, the products can also be used normally after passing the inspection.
