Determination of oil absorption 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 instrument method and manual method for the determination of carbon black oil absorption method, instrument method for the arbitration method. This section applies to rubber carbon black and pigment black.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 7044 pigment black GB/T 8170 rounded repair rules and limit values of the representation and judgment GB/T 15338 carbon black test methods to determine the precision and bias3 principle3.1 instrument method 3.1.1 The degree of aggregation of carbon black particles affect the process of carbon black rubber compound, vulcanized rubber performance. Void volume of carbon black aggregate Depending on the degree of aggregation of the carbon black particles and the void volume is obtained from the volume of oil absorbed by the carbon black, the carbon black oil absorption can be obtained as carbon black particles A measure of the degree of sub-aggregation. 3.1.2 With a constant-speed buret oil is added to the carbon black sample in the oil absorption chamber mixing chamber, as the sample oil absorption increases, the mixed material from The free-flowing state becomes a semi-plastic agglomerate and the viscosity of the mixture increases, which is transmitted to the torque sensing System, when the viscosity of the mixture reaches a preset torque value, both the oil absorber and the constant speed burette are automatically shut off at the same time. From the constant speed burette directly Read out the volume of oil added per unit mass of carbon black to absorb the volume of oil is the carbon black oil absorption value. 3.2 manual method To a certain amount of oil droplets added to a certain amount of carbon black samples, with glass rods on the glass reconcile, stirring, rolling, so that the mixture from Free-flowing state becomes a semi-plastic agglomerate. All of the carbon blacks have a predetermined shape, and can be entirely rolled onto a glass rod, and in the glass No traces of oil on the board for the end.4 test conditionsLaboratory temperature (23 ± 5) ℃. Laboratory equipment and reagents used should be kept at laboratory temperature 24h. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 3780.2-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 3780.2-2017_English as soon as possible, and keep you informed of the progress.
