以废弃珍珠贝壳为原料,经去除角质层、分离棱柱层,得到珍珠层。然后采用机械研磨得到生物填料(ZZB),对其物相、表面元素组成、微观形貌、热稳定性及亲水、亲油性等表面特性进行分析和表征。结果表明,制备的生物填料主要成分为文石碳酸钙,呈片状,粒径大小为0.1~2μm,有机物含量约为3.87%,热稳定性良好。ZZB粉体具有亲水、亲油的双亲性,对正庚烷浸润,对水的接触角约为23.4°。
To discarded pearl shell as raw material, after removal of the stratum corneum, separation prism layer, pearl layer. Then mechanical grinding was used to obtain the bio-filler (ZZB), and its surface, elemental composition, surface morphology, thermal stability, hydrophilicity and lipophilicity were analyzed and characterized. The results showed that the main component of the prepared bio-filler was aragonite calcium carbonate with the size of 0.1 ~ 2μm, organic content of about 3.87% and good thermal stability. ZZB powder with hydrophilic, lipophilic amphiphilic, n-heptane infiltration, the contact angle of water is about 23.4 °.
