【摘要】 本文应用单丝接触角测定仪测定了不同偶联剂处理的玻璃纤维临界表面张力。结果表明:由于固体临界表面张力是描述固体表面性质的物化数据,因此它仅与表面复盖物的性质有关,而与内部的玻璃纤维的成份无关。不同偶联剂处理的玻璃纤维具有不同的表面张力,依次为7114>KH550>A151。沉积在玻璃纤维表面的偶联剂各级分对浸润性能的贡献是不相同的。更多还原

【Abstract】 Monofilament contact angle meter has been used to measure the critical surface tension of glass fiber treated by different coupling agents. Because the critical surface tension of solid is a physico-chemical parameter denotes the surface property of solid and it is only dependent on the nature of cover but independent of the internal constitution of glass fiber. It is found that glass fibers treated by different coupling agents have different surface tensions, the order is as follows: 7114>KH550>A151The components of coupling agent sedimented on surface of glass fiber have different effects on wetting property.更多还原
