1、Designation: D 5267 97 (Reapproved 2005)Standard Test Method forDetermination of Extrudability of Cartridge Adhesives1This standard is issued under the fixed designation D 5267; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the y

2、ear of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method measures the amount of force neces-sary to extrude an adhesive from a cartridge at a giventem

3、perature.1.2 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard

5、ficance and Use4.1 Cartridge adhesives are typically used at job sites in awide variety of temperature ranges. These products may beexposed to cold temperatures, where one of the limitingapplication factors is whether the product can be extruded fromthe cartridge.4.2 The test method quantitatively m

6、easures the force nec-essary to extrude a cartridge adhesive at a given temperature.This provides the formulator with results that can assist informulation development and the end user with information foruse in selecting a product for general usage.4.3 By measuring (the ease of) extrusion from the

7、cartridge,the test method can also be used as a quality control tool tomeasure the shelf life stability of a product.5. Apparatus5.1 The test fixture is shown in Fig. 1. Details are shown inFigs. 2-4.3Make the framework from aluminum. Make the rodand plunger combination from steel.5.2 The test fixtu

11、6. Conditioning6.1 Before measuring extrudability, condition the cartridgefilled with adhesive until it reaches the desired constanttemperature.7. Procedure7.1 Mount the test fixture to the test machine for stability.7.2 After conditioning the cartridge, cut off enough of thetip, perpendicular to th

12、e cartridge, to ensure an inside diameterof14 in. (6.3 mm). If the cartridge has a foil or plastic liner,puncture it completely to allow passage of the material throughthe orifice. Record the temperature of the adhesive by insertinga thermometer or suitable thermocouple into the cartridge.7.3 Set th

13、e crosshead speed to 5.0 in. (127.0 mm) per min oranother acceptable rate.7.4 Activate the machine to begin extrusion of the adhesivefrom the cartridge, measure the maximum force necessary tobegin the extrusion process as well as the force necessary tomaintain continued extrusion of the adhesive. Th

14、e first value isthe force needed to release the plunger from the cartridge. Thesecond value is the force needed to extrude the adhesive fromthe cartridge continuously.8. Report8.1 Report the following information:8.1.1 Complete identification of the adhesive, includingtype, source, date of test, etc

15、.8.1.2 Complete identification of the cartridge, includingtype, composition, liner used, plunger design, source, size, etc.8.1.3 Temperature of adhesive.8.1.4 Crosshead speed used for extrusion.8.1.5 Force (in psi) used initially to extrude the adhesivefrom the cartridge and the average to maintain

16、a constant flowof adhesive.9. Precision and Bias9.1 Precision:9.1.1 Table 1 presents round robin data generated from threelaboratories. Three different cartridge adhesives were used togenerate the data at two temperatures. The extrudability valueswere based on the average of three separate cartridge

17、 values.9.1.2 Repeatability at a given test site for the samplesyielded coefficients of variation from 2 to 18 % for Laboratory1, 1 to 10 % for Laboratory 2, and 2 to 13 % for Laboratory 3,with most values in the range of 2 to 11 %.9.1.3 No statement of reproducibility from site to site isavailable

18、at this time.9.2 BiasBias is the difference between the true forcenecessary to extrude an adhesive from a cartridge and the forcemeasured by a repeatable method. Bias arises from the consis-tency of the adhesive packaged in the cartridge, the method bywhich the plunger is assembled into the cartridg

19、e, and insidediameter variations that may exist when the cartridge tip is cut.10.
