19、004 (E) 41 Scope This document describes a method for determining the volumetric shrinkage of products formulated with thermosetting polymer binders, mainly epoxy and polyester binders, that cure at ambient temperature or below. This method is adapted for crack injection products formulated with pol

20、ymer thermosetting binder. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、 EN ISO 2811-2, Paints and varnishes Determination of density Part 2: Immersed body (plummet) method (ISO 2811-2:1997).3 Test principle The total volumetric shrinkage is calculated as the percentage change in density when the polymer system at (21 2) C cures to the final product also at (21 2) C. Th

22、e density after polymerisation (curing) is measured at (21 0,5) C by measuring the buoyancy of the specimen immersed in silicone oil. 4 General requirements for testing - Apparatus 4.1 balance accurate to 0,001 g, a density measuring device, and suitable wire for suspending the specimen in silicone

23、oil; 4.2 thermometer accurate to 0,2 C and graduated at intervals of 0,2 C or finer; 4.3 silicone oil bath of density Qsiat + (21 0,5) C; 4.4 test tube: diameter 20 mm, length 180 mm in polyethylene or glass treated with a silicone release agent; 4.5 stopwatch; 4.6 desiccator; 4.7 temperature contro

24、lled room or enclosure, capable of maintaining the sample at the recommended constant temperature. EN 12617-2:2004 (E) 55 Test procedure 5.1 Determination of the density of the material before polymerisation Since it is difficult to determine the density of resin systems that react at ambient temper

25、ature owing to their high reactivity and the exothermic heat evolved, determine separately the densities of the components of the resin, at (21 0,5) C to EN ISO 2811-2. Calculate the overall density at time 0, QMO, using the following equation: ()()()ABBABABAMOQmQmQQmmQ+= (1) where QAis the density

26、of component A, in gram per millilitre; QBis the density of component B, in gram per millilitre; mAis the mass of component A used for preparation of a specimen, in gram; mBis the mass of component B used for preparation of a specimen, in gram. 5.2 Determination of the density of polymerized (cured)

27、 material Pour (25 5) g of the resin system as specified in 5.1 into the test tube. After allowing the correct time for polymerisation (curing) at (21 2) C, leave to cool in a desiccator. When cool remove the polymerized specimen from the test tube. Weigh the specimen immediately in air: MFSLthen me

28、asure the apparent mass in silicone oil at (21 0,5) C : M(FS + D)si. and weigh the suspension wire used for weighing: MDL in air. Then remove as much as possible of the silicone oil adhering to the specimen, using filter paper, washing with petroleum ether1). Dry the specimen, for one hour, at (110

29、2) C (for epoxy and polyester binders) and place the specimen in a desiccator to cool to (21 2) C. Weigh again, to establish whether a change in apparent mass has occurred during the measurement with the specimen in silicone oil. The change in weight shall not be greater than 0,2 % of the initial we

30、ight MFSL, otherwise another more suitable immersion liquid shall be chosen. 6 Expression of results 6.1 Calculate the density of the cured material, QFS, rounded to the third decimal, using the following equation: ()siDFSDLFSLsiFSLFS+=MMMQMQ (2) where Qsiis the density of silicone oil, in gram per

31、millilitre; MFSLis the mass of the polymerized (cured) resin in air, in gram; M(FS+D)siis the apparent mass of specimen and suspension wire in silicone oil, in gram; MDLis the mass of the suspension wire in air, in gram. 1) Take appropriate precautions by using organic solvents. This document does n

EN 12617-2:2004 (E) 66.2 Calculate the total volumetric shrinkage, Svol - tot, during the (polymerisation) curing as a percentage rounded to the first decimal using the following equation: 010FSMOFStotvol=QQQS (3) where QFSis the d

33、ensity of the polymerized (cured) product at (21 0,5) C, in gram per millilitre; QMOis the density of the product at (21 0,5) C before polymerization (curing), in gram per millilitre. 7 Test report The test report shall include the following: a) complete identification of the injection product or sy

34、stem tested, including type, source, manufacturers code numbers and history; b) name and address of the testing laboratory and number of the test report; c) reference to this document; d) proportion by weight of the components constituting the product system; e) date and details of preparation of th
