【摘要】 以云南松单宁和糠醇为主要原料,氧化铝颗粒为研磨材料,在实验室条件下制备新型可回收砂轮切割片来替代工业酚醛树脂砂轮切割片。同时对材料的抗压、抗弯性能,布氏硬度及切割性能进行了研究。结果表明:按同一工艺制备的单宁树脂砂轮切割片的抗压、抗弯性能及硬度均高于酚醛树脂砂轮切割片,并且二者的切割性能相似。因此,采用天然可回收云南松单宁树脂砂轮切割片来替代石油产物酚醛树脂砂轮切割是可行的。更多还原

【Abstract】 A new renewable cutting material for grinding wheel,based on the Yunnan pine bark tannin resin and the aluminum oxide particle was prepared.Meanwhile,the Brinell hardness of materials and the properties of bend resistance,press resistance and cutting of materials were studied.The results showed that the test value of Brinell hardness,bend resistance and compression of grinding wheels were higher than that of phenolic resin grinding wheels,which were made in the same process.Thus,it was possible to totally replace the oil-derived resin using nature renewable Yunnan pine bark tannin resin grinding wheel.更多还原
