利用廢輪胎粉及PP短纖廢料製成之複合材料做為浮油回收材料之研究

本研究係利用PP短纖廢料及廢輪胎再利用粉末之物理吸附特性與可壓延特性，做為油品洩漏緊急應時之浮油回收材料；這項創意不但可以解決國內部份PP短纖廢料及廢輪胎處理之問題，且在水體表面浮油回收材料及技術方面也有突破性的貢獻，不僅能簡化浮油回收之困難度亦能增加浮油回收效率。PP短纖做為浮油回收材料，具有吸油快速、吸油量大、不易吸水…等優點，但由於欠缺可抗壓延特性，經壓延除油重複使用後吸油速度減緩，吸油量亦在重複使用過程逐漸降低，至第八次後，減至初始吸油量之一半。反之，廢輪胎粉具有彈性、可抗壓延，重複使用一百次後，吸油效果仍不改變等優點，但其吸量與PP短纖相比則小很多，吸油速度亦較慢。最後，我們綜合PP短纖及輪胎粉之優點，將兩者製作成複合材料，發現新產品之吸油量，比個別產品之吸油量相加還大，可見兩種材料混用，剛好可以利用輪胎粉可重複使用之優點，補足PP短纖之缺點；同時，PP短纖之快速吸油及高吸油量之優點，正好可以補足輪胎粉之缺點。兩者合併後之複合產品則具有高吸油且可以重複使用多次之優點。

Recycled PP fiber cut end and waste tire powder are used as oil adsorbent for the purpose of oil recovery during the process of oil spill emergency response. PP fiber cut end and waste tire powder are capable of adsorbing oil due to their hydrophobic surface property and the capillary forces developed during the contact with oil, therefore, makes them a perfect material for oil recovery. Many of the commercially available oil adsorbent can only be used once. Lack of reusable properties makes the oil recovery process more difficult. In this proposed research, we are using recycled PP fiber cut end and waste tire as a probe to correct the problems. ASTM method was employed to study the oil adsorbing capabilities of PP fiber cut end and waste tire powder. The results were to compare against many other commercially available products, such as 3M and Ecosol. Parameters studied include oil adsorbing speed, oil adsorbing capacity, particle size effects, temperature effects, and the surface tension in confounding with these parameters and many other fundamental properties. The major advantage of recycled PP fiber cut end is its high oil adsorbing capacity. But, after reuse, its oil adsorbing speed was slow down, so does the oil adsorbing capacity. On the other hand, with good elasticity, the waste tire powder can be reused for more than 100 times without loosing its capability. However, the oil adsorbing capacity of waste tire powder is far less than PP fiber. Finally, we combine PP fiber cut end and waste tire powder, to see if we can take the advantage of each one product and make the best utilization of the composite material. Results indicate the composite material can be used for more than 100 times without loosing its capability, and its performance is even better than the combination of each one product. This finding is a big contribution in the future oil recovery processes.
