What are the roof waterproof materials

Biaxially oriented PVC board
Biaxial stretching means that under a specific high temperature, the polyvinyl chloride sheet is stretched 100% in two mutually perpendicular directions, so that the molecular chains of the polyvinyl chloride sheet can be re-arranged in an orderly manner, so that the cohesion of the molecules is large Increase, obviously improve the various physical and mechanical properties of the board. Before stretching, the anti-ultraviolet layer and the polyvinyl chloride layer are co-extruded, and then the two-way stretching process is carried out, which ensures that the anti-ultraviolet layer is evenly and densely covered on the surface of the board, and is completely integrated with the polyvinyl chloride layer. . This process overcomes the weaknesses of ordinary PVC sheets in terms of strength and durability, and becomes a high-end quality material. Its performance characteristics are strong impact resistance, more than twice that of ordinary polyvinyl chloride plates; hail resistance test, stone diameter 30mm, not broken; 50kg heavy sandbag test, can withstand a height of 120cm (plate thickness 1.2mm); Used under low temperature conditions of -30℃; light transmittance can reach 90% (the initial 80% can be maintained after 10 years); impact resistance after 10 years>900kj/m2; impact resistance after bending>500kj/m2 ; Strong corrosion resistance, not affected by the atmosphere, rain, snow and chemical reagents, and will not be swallowed by biological substances; good flame retardant performance, it is a flame-retardant first-class building material.
Scope of application: Two-way stretched PVC panels are divided into colored and colorless. They can be used for waterproofing of large public buildings, industrial plants, stadiums, flower planting and breeding greenhouses, shelters, pavilions, etc.; also available Used in indoor screens, soundproof curtain walls, safety shelters, house walls, guardrails, partition walls, construction site safety barriers, tunnels, etc.
Co-extruded sandwich foamed PVC tile
The production and use of co-extruded sandwich foamed polyvinyl chloride slabs has just started in China. Due to its high production efficiency, reliable quality, reasonable price, and beautiful appearance, it has become a new force in roof waterproof materials. One of its shape is like wavelet asbestos tile, the length can be determined according to needs; the other is similar to the shape of European tile, after the width is determined, the length can be determined according to needs, and the colors can be varied. Its performance characteristics are: light texture, good toughness, strong impact resistance, uniform foam, smooth surface, with the characteristics of planing, nailing, sawing, sticking, and thermoplasticity, which can be processed by molding equipment; weather resistance and corrosion resistance , Anti-ultraviolet, waterproof, insulation, flame retardant, heat preservation, heat insulation, easy to install and construct.
Scope of application: It can be used for sloped roofs of public buildings, residential buildings, factories, etc., and can also be used for interior and exterior decoration, partitions, etc. of buildings. The thickness of the slab is 2-20mm (the current production is mainly 3-5mm), the width is 880-1040mm, and the length can be made according to requirements.
