Bond Strength: The indicator will directly affect the use of sheet rubber insulation board manufacturers and low EPS board strength, shear strength is also low, plate destruction, there may not be out on the adhesive surface, but the middle of the plate directly Good strength properties destroyed, XPS completely at ease 0.1MPa tensile strength equivalent to saying that every square meter tensile strength of 10 tons of force, shear even five tons of it, which is very large. First, the main raw material nature 1 Polystyrene insulation slurry, cement powder: cement powder based on a variety of polymer materials polymerization temperature in the cement mortar from thickening, water retention, crack and so on, but also reduce product cost. 2, cement: cement as particles of polystyrene insulation slurry of the most important raw material, cement is carried out at room temperature, hydration reaction with water to produce gels and crystals, and its strength is dependent on the water and realized, therefore require Polystyrene insulation slurry have enough, persistent water retention, adhesion strong, dry shrinkage smaller. 3, polystyrene particles: particles of polystyrene insulation plays in Polystyrene insulation slurry system, polystyrene particles in the slurry particles of polystyrene insulation products in the amount and thickness of the slurry particles of polystyrene insulation layer construction, directly related to the energy efficiency of insulation Polystyrene insulation slurry system. 4, quartz sand: Quartz sand containing silica, in the role of mechanical forces insulation board factory in Qingdao, more water chestnut into irregular shapes, and the cement slurry to form a strong adhesive force, enhanced slurry bending, anti- compressive strength, will help improve the overall strength of polystyrene insulation slurry of. - Polystyrene particles 5, polypropylene staple fiber: polypropylene staple fiber and mineral wool, glass fiber and other more, polypropylene staple fiber with anti-aging Shanxi insulation board manufacturers, high tensile strength, easily dispersed, the environment and the human body without pollution, etc., play a role in physical tension in Polystyrene insulation slurry particles of polystyrene insulation slurry layer enables a certain tension, cracking action
