Use an evaporating dish with a diameter of not less than 120mm, and the sample size is (5 ± 0.5) g. 5.3 iodine absorption value The test method for the iodine absorption value of waste tire pyrolysis carbon black is in accordance with GB/T 3780.1 proceed. 5.4 moisture content The test method for the moisture content of waste tire pyrolysis carbon black is carried out according to T0103 in JT G E20. 5.5 oil absorption value The test method for the oil absorption value of waste tire pyrolysis carbon black is in accordance with GB/T 3780.2 proceed. 5.6 pH value The test method for the pH value of pyrolysis carbon black from waste tires is in accordance with GB/T 3780.7 proceed. 5.7 granularity The test method for the particle size of waste tire pyrolysis carbon black is carried out according to the dry sieving method of T0302 in JT G E42, and the sieve used for the test should meet the requirements of GB/T 6003.The specification in 1 is ϕ200 × 50-45/4.5 The technical index requirements of the sieve, the sample quantity is 100g.6 Inspection rules6.1 Inspection classification The inspection of waste tire pyrolysis carbon black is divided into type inspection and factory inspection. Type inspection should be carried out in one of the following situations. a) Trial type inspection of new products; b) After the official production, there are changes in the process or raw materials, which affect the performance of the product; c) When production is resumed after suspension of production for more than half a year; d) Periodic inspection when every normal production reaches 500t; e) When there is a large difference between the factory inspection result and the previous type inspection; f) When the national or industry quality and technology supervision department puts forward the type inspection requirements. 6.2 Inspection items The inspection items are shown in Table 2. 6.3 batches, sampling 6.3.1 batch The manufacturer should number the products in batches according to the output, each batch number is 100t, and those less than 100t are counted as one batch. 6.3.2 sampling Randomly select two packs of pyrolysis carbon black from waste tires, stir them thoroughly and divide them into two parts, each part not less than 5kg, seal it well, send one part for inspection, and the other part Save the sealed sample. The products of the same batch number shall be randomly inspected once. 6.4 Judgment rules In the type inspection and factory inspection, if all the performance indicators meet the requirements in Table 1, it is determined that the batch number of waste tire pyrolysis carbon black is qualified. products. If there is one item that does not meet the specified requirements, it is allowed to randomly select two samples from the batch of products to retest the unqualified items. If all the products meet the standard requirements, it will be judged as qualified; otherwise, the batch of products will be unqualified. 7 Labeling, packaging, transportation and storage 7.1 Marking and packaging 7.1.1 Pyrolytic carbon black from waste tires should be packaged in paper bags or plastic bags that are moisture-proof, not easy to break, and have an inner film. The package should include the following. a) product name and model; b) net mass; c) The name and address of the production unit. 7.1.2.Each batch of products should be accompanied by instruction manuals and a certificate of conformity. In addition to the above contents, the certificate of conformity should also include the following contents. a) place of manufacture; b) date of manufacture; c) production batch number; d) Quality inspectors; e) Inspection implementation standards; f) Test results. 7.2 Transport and storage The product should be protected from sunlight, stains and scratches during transportation, and the outer packaging should be kept intact; the product should be stored in a dry warehouse, the temperature is not If the temperature exceeds 40°C, the storage period should not exceed 24 months. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JT/T 860.7-2017_English be delivered?Answer: Upon your order, we will start to translate JT/T 860.7-2017_English as soon as possible, and keep you informed of the progress.
