This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 3780.17-2008 "Part 17 carbon black. Indirect determination of particle size reflectance method", and GB/T 3780.17-2008 compared to the main changes are as follows. --- Removed the foreword "Part 11. Sieve residue determination"; --- Modify the normative references lead to meet the new standard format requirements; --- Modify the normative references in the "wire braid screen test sieve" standard number and standard name, because of a new standard and the original standard Number is wrong (see Chapter 2); --- Modify the normative references GB/T 8170 standard name, because the new version of the standard name change (see Chapter 2); --- Increasing the reference standard "carbon black Part 8. Determination of heat loss" (see Chapter 2); --- Modify the third chapter of the principle of the content of the statement; --- Added Chapter 4 materials, improve the structure of this standard; --- "Controllable temperature (125 ± 5) ℃" to "temperature can be controlled at (125 ± 2) ℃" (see 5.1,7.1); --- Modify the order of sample preparation, from the first dried sample and then sieve modified to sieve and then dried samples, to ensure that the sample was dry State (see 7.1,.2008 version 6.1); --- Modify the reflectometer positioning to fit more types of reflectors (see 7.3.1). This part is proposed by China Petroleum and Chemical Industry Federation. This part of the National Rubber and Rubber Products Standardization Technical Committee (SAC/TC35) centralized. This part of the drafting unit. Hao Zhongyuan Black Chemical Research Institute Co., Ltd., Ningbo Taktai Chemical Co., Ltd.. The main drafters of this section.

Carbon black Part 17 - Indirect determination of particle size Reflectance method Warning --- personnel using this section should have formal laboratory work experience. This section does not indicate all possible safety issues question. It is the user's responsibility to take appropriate safety and health measures and to ensure compliance with the requirements of the relevant state laws and regulations.1 ScopeGB/T 3780 provisions of this part of the indirect determination of carbon black particle size using a reflective test method. This section applies to rubber with carbon black (furnace method).2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 3778 carbon black rubber GB/T 3780.8 Carbon black Part 8. Determination of heating loss GB/T 6003.1 Test sieves - Technical requirements and testing - Part 1. Wire mesh sieve test sieves GB/T 8170 rounded repair rules and limit values of the representation and judgment3 principleThe reflectance of the carbon black plane is directly measured by a reflectometer, and the average particle diameter of the carbon black is calculated according to the relationship between the particle size and the reflectance. The reflectance The smaller, the smaller the average particle size of carbon black.4 materialIndustrial Reference Carbon Black 7 (IRB7).5 equipment5.1 oven, gravity convection type, the temperature can be controlled at (125 ± 2) ℃. 5.2 brush, flat, long hair not less than 2cm. 5.3 scraper. 5.4 test sieve, Φ200mm × 25mm/0.075mm, in line with the provisions of GB/T 6003.1. 5.5 Reflectometer, photoelectric type, can measure the difference between the reflectivity of the blackness gradient. 5.6 Sheng-like tank, the outer width of l1, the inner tank width l2, outer length l3, inner tank length l4, groove depth h1, thickness h2, see Figure 1 and Figure 2. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 3780.17-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 3780.17-2017_English as soon as possible, and keep you informed of the progress.
