Classification5.1 Classification by application method includes: troweled(TR), broadcast (BC), slurry broadcast (SBC), self-leveling(SL), spray (SP), and reinforced (RF).5.2 Classification by resin chemistry includes epoxy (EP),urethane (UR), polyest

19、er (PE), and vinyl ester (VE).6. Materials6.1 Most of these systems include three components: aresinous liquid, a liquid setting agent, and an aggregatecomponent.6.2 The resinous liquid shall be epoxy, urethane (polyol),polyester or vinyl ester.6.3 The setting agents for these materials are usually

20、amines(for epoxies), isocyanates (for urethanes), and peroxides (forpolyesters and vinyl esters).6.4 The aggregates or fillers are usually siliceous or carbo-naceous materials. These materials are selected to have ad-equate resistance to the chemicals that are in the area wherethey are installed and

21、 are properly sized to provide ease ofapplication.6.4.1 Other aggregates and/or filler components are fre-quently used to obtain specific properties.Aluminum oxide andsilicon carbide are used to provide increased abrasion and/orslip resistance properties in the flooring system.6.5 Reinforcing materi

22、als used with these flooring systemsmust themselves be chemical resistant. Such materials includesynthetic, carbon or fiberglass materials in mats, strands orrovings.6.6 The surfacing materials for TR, SL and SP systems areusually installed by mixing the resin with the setting agent,blending in the

23、aggregate component until uniform and ho-mogenous, and then placing and finishing the mixture onto aproperly prepared concrete substrate as per Practice C811.6.7 The surfacing materials for BC systems are usuallyinstalled by mixing the resin with the setting agent (calledliquids here), and then spre

24、ading onto a properly preparedconcrete substrate. This is followed by broadcasting the aggre-gate to excess into the wet film. The application is allowed toharden. The excess aggregate is removed. The surface is thentopcoated with the same liquids or the application process isrepeated until the desi

25、red thickness is reached, and then thesurface is topcoated.6.8 In a SBC system, the resin, setting agent and aggregateare blended and applied on a properly prepared concretesubstrate. More aggregate is then broadcast into this slurry andallowed to harden. The excess aggregate is removed and thesyste

26、m is then topcoated.6.9 RF systems are usually applied as the TR, SL or SPsystems. The reinforcement is usually embedded in this layerand then the reinforcement is saturated with liquids. A secondTR, SL, or SP layer is then applied.6.10 The components of the floor surfacing systems areusually formul

27、ated to perform optimally at specified mixingratios. They are usually either packaged by the manufacturer inthe required proportions (weight or volume) or mixing instruc-tions include guidelines for mixing proportions.6.11 Any of these systems may be topcoated. At therecommendation of the manufactur

28、er of the system, thistopcoat may be mandatory for optimal appearance and perfor-mance.6.12 Many floor surfacings include some type of finishtexture or profile incorporated into the design of the surfacethat can range from relatively smooth to extremely aggressive.TR systems without a sealing topcoa

29、t, BC and SBC systemsinherently produce surfaces with a texture. SL systems usuallyproduce a smooth surface. Other common methods for incor-porating texture include: broadcasting an aggregate into atopcoat (and optionally, resealing); or mixing an aggregatedirectly into the topcoat before applicatio

30、n.6.13 Occasionally, floor surfacings are required to havespecific conductive or static dissipative electrical properties forpersonnel or product protection. Specific requirements forelectrical resistance are not covered in this standard. Refer toESD-S7.1 for test methods to determine this property.

31、6.14 In areas where flammable materials are present, it maybe required that floor surfacings be non-sparking when im-pacted with metallic or other hard materials. Specific require-ments for non-sparking properties are not covered in thisstandard.7. Physical Properties, Chemical Resistance andPerform
