GB/T 4617-2009/ISO 59. 1976 Phenolic plastic moldings Determination of acetone-soluble matter1 ScopeThis standard specifies the method for the determination content by weight of acetone extract from the ground near the boiling point of the phenolic moldings soluble matter. This standard applies to Phenolic moldings - Determination of acetone soluble matter. Acetone soluble test is to determine the phenolic moldings given material relative degree of curing methods. The extraction process should be specified Under the condition, within a predetermined time. Although the vast majority solubles measured out, but the effects may not be entirely extracted. As a result, more than just Than in nature, except as may be present in the uncured resin extract, usually also contain other substances such as a lubricant, a colorant and a plasticizer. Principle 2 Heating the acetone extract solubles have been processed into fine powder sample, the acetone was distilled off, extracts dried and weighed to constant weight.3 ReagentsAcetone, AR.4 Instrument4.1 the device, the molded article of the device into a fine powder; 4.2 sieve, with a nominal pore size of 425μm (GB/T 6005-2008); 4.3 sieve, with a nominal pore size of 250μm (GB/T 6005-2008); 4.4 scale, indexing is 0.001g; Extractor 4.5. 1. You can use the Soxhlet extractor. The instrument casing material by the boiling of the solvent vapor surrounded. Just to prove that it can also give similar The result can also use other types of extractor. 4.6 Oven. blast type, the temperature can be controlled at (50 ± 2) ℃.
