Plastics science platic
Plastics science is a science based on plastics. It can process the material into a product by adding agents (or additives) at a specific temperature and pressure. The industry sometimes regards synthetic resins as the basis of plastics. 9.3
Microlysis prnksis
The chemical process of converting the test materials into "and" or more substances only by heat energy. Cracking is also called thermal cracking. The mixture of volatile substances generated by the cracking of synthetic resins is called thermal cracking gas. 4 Collection and preparation of test|| tt||4.1 The sampling method shall be carried out in accordance with GB/T009.156. 4.2: Sample preparation
After surface cleaning, the test group shall be put into small strips (50mmX10mm), small pieces (10mm×1mm), rice pieces, etc. for test use.
5 Test method
Introduce the dirty
Take the test piece or water. Put it into a 5m burning standard, and then fill the standard with about 50m of 10)/t sodium sulphate (Na:50,235)

5.2.2.1 Lead sieve preparation
Use a knife to remove the stem part and make the lead core into a shape, the lead core is exposed about%mm Then, place a piece of sandpaper on a hard surface, and straighten the paper surface along the edge. Then, grind the surface of the paper in a circle and make it smooth, until the surface is smooth and the edges are sharp. 5.2.2.2 Scratching the sample
Place the sample on a flat surface, and make the sample horizontal. Hold the pencil at a 45 degree angle, and do not break the pencil. Push the new pencil toward the tester with a uniform speed (about 1n/) for about 1 second, and scratch the surface of the plastic. Use a hard pencil to scrape it. When scraping, be sure to grind the new pencil to keep the surface and edges sharp. 2.2.3 Result judgment
In the test of the lead pencil, if there are more than two scratches that are considered to be scratch-free, the lead pencil with a higher hardness should be replaced to repeat the above test process. Until there is one or more scratches on the surface, the hardness of the pencil with a lower hardness than this one is recorded, and the corresponding item is recorded.

5.4.2 Analysis steps
5.4.2.1 Acid-base test
Put a small hard test tube under heat and put several grains of sample in it. Heat it carefully over a low fire to make the crack produce smoke. Put the moist H2O paper or other red paper in it and let it touch the gas. Observe the color change of the test paper and judge by referring to Record B. 5.4.2.2 Mercury test paper test
The test paper is yellowish when it is combined with propylene. The propylene-terminated resin and its derivatives will not show yellow. Take the sample according to 5.4.2.: Heat cracking. Let the test paper touch the gas and observe whether it turns yellow. Judge by referring to Record B. 5.4.2.3.2.4.2.6 Test paper for dimethoxybenzyl alcohol This test is used to identify FA. The test paper turns red as a positive. This test is used to identify PMMA. The test paper changes color as a positive. 4.2.1 Thermal decomposition, the test paper is exposed to flue gas. Observe the color change of the test paper. Judge according to Appendix B: 5.4.2.4.2.6 Test paper for dimethoxybenzyl alcohol This test is used to identify FA. The test paper turns blue or blue-tinted as a positive. This test is used to identify FF. The test paper changes color as a positive. Judge according to Appendix R. 5.4.2.5 Formaldehyde-resistant test This test is used to identify P. The test paper changes color as a negative. The sample is heated and dissolved as in 6.4.2.1. The test paper is exposed to the flue gas and the color change of the test paper is observed. The judgment is made according to the following procedures: 5.4.2.6 Picric acid test paper test
This test is used to purchase PA, AS, ABS and other nitrogen-containing high-chain substances, or the color of the test paper turns red to red. 5.4.2.1 Heat treatment, first use 1 ((/1.5) sodium hydroxide solution to wet the bitter taste test paper to connect the flue gas, observe the color change, and refer to Appendix 3 for segmentation.
5.5 Pyrrolidone test
This test is used to distinguish PVC from PVD.
Test the mixture with a certain amount of hydrogen, and thoroughly dissolve it with a tablet. If necessary, filter out the impurities. Collect the liquid, slowly add the solvent to the filtrate to precipitate again, filter out the solvent, collect the precipitate, evaporate it and remove the residual solvent in the precipitate. Add 1mL of pyrrolidone to the obtained powder. After a few minutes, add 2-3 drops of 5g/mL sodium methoxide and observe the color change immediately. If reddish brown or colorless appears, it is PVC; if brownish black appears, it is PVTC. 5.6 MF and UF are distinguished by the change of surface gloss of the wood products: soak the sample in water for 1 minute. Take it out and observe its surface gloss. MF does not lose its gloss, while LF loses its gloss after boiling. 5.7 Monomer determination 1. PVC, PS, A*, ABS and other resins are determined according to the methods specified in GR/T5009.125, GB/T5009.67, GB/T5009.166-2003. In general, when only qualitative identification is required, the G determination of a single piece can be omitted. 6 Judgment of test results 6.1 The step-by-step identification process shown in the appendix can indicate the method of sample identification test and show the various The relative relationship between the resins and the possible tension between the samples shall be determined according to the test items in Appendix B. The sample numbers of the positive test results shall be recorded. Each test sample can be coded with a test number. This code shall be compared with the test number code recorded in the test. The sample tested is a new sample. For example, the test number code of the positive test result of the Laiyun sample is:
A1,3,d.,B1.c2,4.6,.0.11.13.1,4,Ft. After checking Appendix L, it can be known that the sample is PVC resin. 6.3 If there is a discrepancy between the test number code and the Appendix D code, the test number can be re-tested. Since the evaluation of the test results is a comprehensive judgment of multiple qualitative test results, some special characteristics of the comprehensive qualitative test should be noted. 373||t t||Bring it inside
