light weight partition wall board

ALUMARK lightweight partition wall board uses inorganic binder as the main raw materials,and is made by adding glass fiber grid layout,fire retardants,and other high-performance materials,forming a precision casting ,with superior performance.1. Green Environmental ProtectionThe products use natural plant fibers.It has the merits of environmental protection,energy saving,no pollution and no radiation.It can be reduced.2,Light TextureAbout 36kg/-1/9th in weight of the traditional brick wall,the wall can effectively reduce weight .Thus the input of the basis and structure can be reduced.3.High StrengthGlass-fiber products,using the grid layout enhanced and supported by a variety of high-performance compound modifier, are molded by precision casting at a time.It has the merits of high strength,good toughness and non-deformation.4.WaterproofIt can be widely used in kitchens,bathrooms and other renovation work.5.Fire preventionAdded a flame retardant product, it does not produce harmful gases in high temperature. Combustion property is Class A non-combustion .it can be widely used as a firewall.6.Sound BarrierThe hollow-structured product forms a large number of confined stomatals , with double performances of sound-barrier and sound-absorbing, providing modern society with quiet and comfortable living environment.7.Temperature MaintenanceAfter testing, the product performance is better than that of the same thick brick wall or other walls.8.Easy InstallationIt has the following merits: capability of being sawn, shavered, drilled and linked; forming rapidly ; non-deformation while drilling ; good bonded performance with a variety of coatings or cement mortar; hollow-designed products also facilitates the construction of hydropower construction for threading through the installation ,effectively shortening working hours, improving more than double work efficiency.Test itemNational standardTest resultWeight(10cm thickness)60Kg/m235 Kg/m2Bending failue load0.75 KM6.5 KMResist impact strengh(30kg sand bag)3 times500 times no crack Sound insulation40dB43dBMax fire resisitance A grade 60min188 minSingle point hanging force≥800N850N no crack by haning 24 hoursWater resistance7 days No change in water for 8daysExtremely cold and hot20 times cyclesNo change by 20 times cyclesAcid and alkali proofIn 5%HCLliquid soaking 24 hoursNo change by soaking 30 hoursWater absorption 20%18%Dry shrinkage≤0.8mm/m0.75mm/mBending ≥20002491Thermal conductivity0.4816W/M.KFreeze-thaw cycle No slip crack26times cycle no slip crackInternal radiation index 1Rn≤1.00.35External radiation index 1V≤1.30.71
