摘要
对滴灌管（带）产品炭黑含量和炭黑分散进行试验研究，得出了滴灌管（带）产品中炭黑含量与分散的对应关系：随着炭黑含量的增加，其分散等级也在缓慢增大；炭黑含量在（2．25±0．25）％的范围内，其分散等级为1．4～2．6级，而炭黑分散均合格的情况下（≤3），炭黑含量变化较大；热压片法制备滴灌管（带）产品炭黑分散试样的最佳条件为加载质量5kg，最佳温度≥190℃，时间≥1．25h。
AThe effect of carbon black content on its dispersion in drip irrigation pipe was studied. With increasing of carbon black, the dispersion slowly increased. When the content was about （2. 25-4-0. 25） %, its dispersion was in grade 1.4~2. 6. In addition, the optimal preparation condition was given： the loading weight of 5 kg, the optimum temperature of over 190 ℃, and the time over 1.25 h.
