| 中文摘要: |
| 研究用低温氮吸附法测定炭黑的比表面积，考察预处理方式、预处理温度、预处理时间、饱和蒸气压准确性等因素对炭黑比表面积测试结果的影响。结果表明，使用具有防污染装置的真空加热方式对炭黑进行预处理、预处理温度为200 ℃、预处理时间为3 h、保证饱和蒸气压的准确性，炭黑比表面积的测试结果更准确。 |
| 英文摘要: |
| The specific surface area of carbon black was determined by low temperature nitrogen adsorption method and the effects of pretreatment mode，pretreatment temperature，pretreatment time and accuracy of saturated vapor pressure on the test results of specific surface area of carbon black were investigated.The results showed that the vacuum heating method with anti-pollution device was used to pretreat carbon black，the pretreatment temperature was 200 ℃，pretreatment time was 3 h，the accuracy of saturated vapor pressure was guaranteed，and the test result of specific surface area of carbon black was more accurate. |
