国家边防局修改了沥青膜

Products Detail(1)SBS modified bitumen membrane is made by saturating the base in bitumen, or thermoplastic elastomer (such as styrene butadiene-SBS), reinforced with polyester or fiberglass, finishing the upward face with fine sands, mineral slates(or grains)or polythene membrane etc. (2)Characteristic: a)Good impermeabilityb)Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack.c)SBS modified bitumen membrane is specially being applied in the cold area with low temperature , d)Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering (3)Specification: Item TypeGrade IIIReinforcementPYGPYGSurfacePESMThickness2mm3mm4mm5mmWidth1000mm Applicable scope Suitable for civil building roofing, underground, bridge, parking, pool, tunnel in the line of waterproofing and dampproof, especially for the building under high temperature. According the roofing engineering stipulation, APP modified bitumen membrane could be used in the Grade I civil building and industrial building which has special waterproofing requirementAttentions for ConstructionConstruction shall not be carried out in rain, snow or over 5 degree wind weather; Thereshall be sufficient safety protective facilities in construction site, place firefighting devices according to stipulations.Installation Sketch point1)Clean the substrate using broom or high pressure dusty cleaner.2)Apply primer3)Heat the membrane bottom using a high temperature flame gun.4)Push forward while the primer and membrane oil melted5)Use a roller to push hard the membrane surface to ensure it stick firmlySBS Technical data Confirming to GB18242-2008No. ItemIIIPYGPYG1Soluble content/(g/m2)≥3mm21004mm2900TestNo flameNo flame2Heat Resistance°C90105≤mm2Testno flow no dripping3Low temperature flexibility/°C-20-25no crack4Impermeability 30minutes0.3Mpa 0.2MPa 0.3MPa 5TensionMaximum/(N/50mm)500350800500Secondly-MaximumTestno crack no apart6ElongationSecondly-Maximum≥3040Secondly-Maximum≥7Oil Leaking Pieces≤2
