ASTM D1582-1998(2004) Standard Test Method for Nonvolatile Content of Liquid Phenol Resorcinol and Melamine Adhesives《液相苯酚、间苯二酚和三聚氰胺胶粘剂中不挥发物含量的测试方法》.pdf

1、Designation: D 1582 98 (Reapproved 2004)Standard Test Method forNonvolatile Content of Liquid Phenol, Resorcinol, andMelamine Adhesives1This standard is issued under the fixed designation D 1582; the number immediately following the designation indicates the year oforiginal adoption or, in the case

2、of revision, the year 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 covers the determination of nonvolatilecontent or total solids of liquid ph

3、enol, resorcinol, andmelamine adhesives with or without hardener (Note 1) addedand containing high-boiling and low-boiling volatile organicsolvents or water, or both.NOTE 1Some low molecular weight materials in the adhesive may belost if hardener is not used. When a hardener is used, it must be mixe

4、d inaccordance with the manufacturers instructions.1.2 The values stated in SI units are to be regarded as thestandard.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 to establish appro-pri

5、ate safety and health practices and determine the applica-bility of regulatory limitations prior to use. For specificprecautions, see 5.2.2.

6、ogy D 907.4. Summary of Test Method4.1 Without HardenerA weighed amount of adhesive andquartz sand are oven-dried, cooled in a desiccator, andweighed. The percent nonvolatile content is calculated basedon the amount remaining.4.2 With HardenerA weighed amount of mixed adhesiveis oven dried, cooled i

7、n a desiccator, and weighed. The percentnonvolatile content is calculated based on the amount remain-ing.5. Apparatus5.1 Petri Dish, 100 by 22 mm or its equivalent.5.2 Circulating-Air Oven, capable of maintaining tempera-tures of 70 6 1C, 105 6 1C, and 150 6 1C. (WarningAsafety (explosion-proof) ove

8、n should be used when volatilematerials are likely to burn or explode.)5.3 Desiccator, with drying agent and tray.5.4 Analytical Balance, accurate to 1 mg.6. Sampling6.1 Except in special cases, take a composite sample fromthree or more separate containers chosen at random. Also, takesamples from co

9、ntainers which appear to be nonrepresentativeand test such samples separately. Place the samples immedi-ately in airtight containers, filled to prevent excessive air spaceabove the adhesive, and take precautions to reduce evaporationor drying to a minimum. Mix the adhesive in the containerthoroughly

10、 if there is a tendency for the materials to separate.6.2 Test three specimens of each sample.7. Procedure7.1 70C Drying Temperature Without Hardener:7.1.1 Place approximately 20 g of the adhesive in a coveredweighing bottle.7.1.2 Place approximately 10 g of fine, oven-dried quartzsand in an open Pe

11、tri dish, together with a small glass stirringrod, and weigh the dish, rod, and contents to the nearest 1 mgon the analytical balance. Weigh out to the nearest 1 mgapproximately2goftheadhesive by difference from theweighing bottle, keeping the bottle covered as much aspossible. Mix the adhesive and

12、quartz sand intimately bymeans of the stirring rod and distribute uniformly over thebottom of the dish in as thin a layer as possible. Condition thespecimen at 23 6 1C for at least 16 h.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of
