Sewage Pumps for Municipal and Industrial ApplicationsPlanning GuideCeram C1 Technical dataDescriptionCeram C1 is a cold-hardening, solvent-free ceramic compoundmaterial based on two components with selected reinforcementfillers and extenders.CompositionPolymer/ceramic compound material made of a matrix and reinforcement.Matrix: A modified polymer made up of two parts with an aliphatichardening agent.Reinforcement: A mixture (protected by proprietary rights) made upof aluminium oxide and extenders.This ceramic mixture has excellent abrasion strength and can beappliedvery easily.Properties- The completely hardened Ceram coating C1 has a glossy finish, hasno pores and is easy to clean, mechanically very stable, abrasionproofand has excellent adhesion.- Ceram C1 hardens without shrinking and is stable against a largenumber of chemicals, oils, greases, solvents, diluted organic andinorganic acids and bases and saline solutions.- Ceram C1 reduces friction and improves flow and efficiency.-Excellent corrosion protection.Technical dataHardness Buchholz 115Density / mixture ASTM D 792 1.4 g/cm³Shrinkage during hardening ASTM D 2566 0.002 mm/cmTension / shear resistance ASTM D 1002 13.8 N/mm²Tensile strength / ultimate ASTM D 638 26.2 N/mm²strainCompressive strength ASTM D 695 60 N/mm²Bending strength ASTM D 790 55.2 N/mm²Adhesion / steel ISO 4624 13.8 N/mm²Impact resistance / strength ASTM D 256 11 J/mCoefficient of linear expansionASTM D 696 34.5 x 10 –61 1/KElectric resistance ASTM D 257 8 cmHeat conductance ASTM C 177 0.7 W/m x KPorosity test Test stress 5 V/m layerthicknessTemperature stability, dry ASTM D 648 140°CTemperature stability, wet ASTM D 648 60°CStability tableFluidFactorAcids10% sulphuric acid 220% sulphuric acid 35% hydrochloric acid 110% hydrochloric acid 220% hydrochloric acid 35% nitric acid 110% nitric acid 35% phosphoric acid 120% phosphoric acid 3Bases and bleaches10% sodium hydroxide 150% sodium hydroxide 15% ammonia 228% ammonium hydroxide 110% potassium hydroxide 150% potassium hydroxide 16% fixing salt 15% soap solution 1Cement mortar / concrete 1Other compoundsIsopropanol 1Kerosene 1Naphtha 1Salt water 1Sewage 1Toluene 1Xylene 1Bunker C 1Diesel oil 1Tested at 20°C.
