Plastics inspection Testing and plastics crushed1 ScopeMany plastic products, analysis and testing, sample requirements particularly large specific surface area, such as determination of extractable components. Thus, plastic Products often require grinding. The method described in this standard are applicable to molded plastic, semi-finished plastic and plastic molded parts. Crushed by the product Pre-crushing and pulverization of the final composition. According to the type of product being crushed, the purpose and the desired particle size of the pulverized material, select the appropriate method. Note. Within the scope of this standard, it is impossible for any of the tests are given appropriate equipment. This standard is intended for a number of standards and guidelines for the full complement of information, Provide the most appropriate method of pulverizing, and provide a variety of methods may be useful to crush the test sample.2 SamplingRemove from plastics can test a representative sample of the finished product characteristics. If the area of the different components of the test found a clear plastic (visible) different components, whenever possible, should be crushed before Separated and then individually crushed.3 PrepareSample preparation 3.1 Wiping, washing or scraping methods to remove other substances plastic sample surface carefully. Prepare 3.2 devices Before use, carefully clean the grinding equipment, such as removal of residual material rust and previous testing.4 Device4.1 Summary Crushing equipment selection should consider the following factors. a) the number of samples; b) the sample is crushed condition, such as. size and shape, toughness and hardness; c) the sample size required to be crushed; d) requires several grinding process. A small amount of sample can be crushed simple tools, for example, file, knife, scissors; a large number of samples with an electric machine, such as flour Broken machine. When you select the application tools and machines should be considered to be crushed sample status (such as. hard, soft, brittle, tough, elastic) and to be Seeking particle size, if necessary, be dealt with in stages, for example, first with a saw, grinder after use. When crushing plastics, in particular grinding machines, should pay attention to the test material is not melted or melting. When grinding machines, should adopt appropriate Operating conditions (cutting and injection speed, circumferential speed). In addition, especially pulverized soft, tough, flexible material, it requires cooling crushed Equipment and/or pre-cooled sample. 4.2 Pre-crushing equipment 4.2.1 Simple crushing tools Scissors, knives, pencil or knife grinder, rasp, rasp, paper drilling machines, paper cutter, mortar, handsaw. NOTE. flat rasp suitable for processing thermosetting plastics and semi-finished products and finished parts. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 22236-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 22236-2008_English as soon as possible, and keep you informed of the progress.
