摘　　要：对表面涂层活性炭的制造工艺及配方和产品性能参数进行了研究，通过正交试验找出了较佳配方：表面涂层剂１９份，水７０份，稳定剂７份，粘结剂１２份。由较佳配方所研制的表面涂层炭若原料炭的碘值为６８０．６ｍｇ／ｇ，吸苯率为１７．７％，则制得的表面涂层炭性能为：碘值６５２．３ｍｇ／ｇ，吸苯率１７．９％，炭粉减少率９８．８％；若原料炭的碘值为１０２０．３ｍｇ／ｇ，吸苯率为３２．２％，则制得的涂层炭性能为碘值９８１．ｌｍｇ／ｇ，吸苯率３０．８％，炭粉减少率９８．５６％。本表面涂层技术工艺简单，易于操作，不影响炭的吸附性能，且成品炭表面光滑，触手后不变黑，不易磨损，性能稳定，因此扩大了活性炭使用性能及应用范围。With omhogonal design, researches on the technology and prescription of surface coating of granular acdvated carbon, and measurement of its performance parameten were canied out. Based on the studies, a best prescription was selected, the optimum is as follows: coating agent: 19, water: 70, stabilizing agent: 7, adhesive agent: 12. The surface coating carbon produced according to the presc.pdon is more functional, which enjoys many advantages: smoothness on their surface, wearability, no Machining hand and nice looking and absorptive powe. lf the iodine value of raw acdvated carbon is 680.6mg/g and the rate of benzene absorption is 17.7%, the performances parameters of the products are Iodine value: 652.3mg/g, the rate of benzene absorption is 17.9%, deducting rate: 98.8%. lf the Iodine value of raw acdvated carbon is 1020.3mg/g and the rate of benzene absorption is 32.2%, the pe.rmances parameters of the products are lodine value: 981.1 mg/g, the rate of benzene absorption is 30.8%, deducing rate: 98.56% This technology is easy to control and not complicated, funhermore, thc absorption ability of carbon won't be affected, so this study will expanded the use range of acdvated carbon.
