SBS and APP Modified Bituminous Waterproof Membrane

详情

Introduction
SBS/APP Modified Bituminous Waterproof membrane is a kind of flexible waterproof material which using Stylene-Butadiene-Stylene (SBS) thermoplastic elastic modified bitumen/atactic polypropylene (APP) or polyolefins(APAO,APO) as dipping and coating material, polyester or fiberglass as reinforcement material, and polyethylene film, fine sand, mineral slice (or particle) as insulation material.
Features
1) High tensile strength, high elongation, high adaptive capacity to shrinkage deformation and fracture of base.
2) Excellent high temperature resistance, particularly suitable for hot region and good performance on root penetration resistance, fatigue resistance, corrosion resistance, mould resistance and aging resistance.
3) Good workability: It can be constructed by heat fusion method in the four seasons of the whole year and hot-joint is reliable and durable. 
Application scope
1) Industrial and civil buildings of the roofs and basements,
2) Swimming pool, fire-water pond, channel, pipe drain.
3) Railway, highway, subway and tunnel waterproofing projects.
4) Especially adapt to the area with strong sunshine or high temperature.
Construction Guideline
1)basement pretreatment: Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and surface irregularities need to be filled by polymer mortar.
2) Before membrane laying, brush the primer on basement evenly and completely cover all laying places.
3) heat the membranes evenly, pave the membranes on basement according to the alignment  and keep the membrane straight and smooth, ensure the joint area min. *0 mm overlap (length and width). Press the membranes tightly to make sure the trapped air to be excluded and the membranes bonded with basement firmly, no bubbles and wrinkles allowed. It also can be applied strip adhesion method and border adhesion method. 
4) seal the edge of joint by automatic crawling welding machine or hand-hold welding gun, no miss welding and fake welding allowed. Sealing, fixing and constraining on vertical surfaces, on vertical surfaces, fix with metal battens and seal with sealants for membranes.
5)Application on protection and isolation layer, after membrane laying, construct protection and isolation layer according to waterproof layer design.
Cautions
1) Dont install in the rainy days or the temperature is lower than 0 ℃.
2) all the workers should put on special uniforms to keep safe during installing, take fire safety precautions and fire equipments should be prepared.
Storage and Transportation
1) Different items, models, dimensions and grades should be stored separately. 
2. Store the products in a dry and ventilated place with the storage temperature less than *0℃, and products should be placed upright and stacked no more than two layers.
3) Keep products in an upright position during transportation., avoid incline and cross squeeze between rolls.
4) The shelf-life is one year under normal storage condition.
