4 Technical requirements
GB3778-94
Each grade of carbon black should meet the requirements of the corresponding technical indicators in Table 1. 5 Test methods
5.1 Before measurement, except for the impurity inspection items, the sample must pass an 850 μm sieve. 5.2 The determination of iodine absorption value shall be carried out in accordance with GB/T3780.1. 5.3 The measurement of DBP absorption value is carried out in accordance with GB/T3780.2. 5.4 The measurement of DBP absorption value of compression specimens shall be carried out in accordance with GB/T3780.4. 5.5 The determination of CTAB adsorption specific surface area shall be carried out in accordance with GB/T3780.5. The determination of 5:6 tinting strength shall be carried out in accordance with GB/T3780.6. 5.7 The determination of nitrogen adsorption specific surface area shall be carried out in accordance with GB/T10722. 5.8 The determination of pH value shall be carried out in accordance with GB/T3780.7. 5.9 The measurement of heating test volume shall be carried out in accordance with GB/T3780.8. 5.10 Ash content measurement shall be carried out in accordance with GB/T3780.10. 5.1145um and 500μm sieve residue measurement shall be carried out in accordance with GB/T3780.21. 5.12 The measurement of 150μm sieve residue shall be carried out in accordance with GB/T3780.11. 5.13 Impurity determination shall be carried out in accordance with GB/T3780.12. 5.14 The determination of tensile strength, elongation at break and 300% elongation stress shall be carried out in accordance with GB/T528 and GB/T3780.18. 6 Inspection Rules
6.1 Inspection of carbon black for rubber is divided into factory inspection and routine inspection. 6.1.] Factory inspection: various inspections that must be carried out when the product leaves the factory. The test items are as follows: aN100N900 series are tested for iodine absorption value, DBP absorption value, impurities, CTAB adsorption surface area, 45μm, 150um, 500um sieve residue, tensile strength, 300% tensile stress, and elongation at break; b. S200~~S300 series and natural gas channel carbon black and mixed gas carbon black are tested for CTAB adsorption specific surface area, DBP absorption value, pH value, 45um, 150μm, 500um sieve residue, impurities, tensile strength, 300% elongation stress , elongation at break (s series physical properties are only measured at 300% elongation stress);
c. Natural gas semi-reinforced carbon black is tested for iodine absorption value, DBP absorption value + pH value, 45μm, 150μm, 500μm sieve residue, impurities, tensile strength, 300% modulus stress and elongation at break. 6.1.2 Routine inspection: A comprehensive assessment of product quality, that is, a full inspection of the technical indicators specified in the product standards. When any of the following situations occurs, perform routine inspections. a.
Trial prototype identification of new products or old products transferred to factory production; b.
Formal After production, if there are major changes in raw materials and processes that may affect product performance; during normal production, inspections will be conducted regularly or periodically after a certain amount of production has been accumulated to assess the stability of product quality; when production is resumed after a long-term suspension of production; When the factory inspection results are significantly different from the last inspection results; when the national quality supervision agency proposes routine inspection requirements. 6.2 Sampling
6.2.1 Sampling Tools
a. Stainless steel sampling spoon with handle;
Sampling tube: The main tube is a hard plastic or stainless steel tube. The sealing plate is a rubber plate, its inner hole is slightly smaller than the outer diameter of the main pipe, and it can move axially along the main pipe b.
. The schematic diagram is shown in the figure below.
