本文利用偏光显微镜研究了等温结晶时尼龙1010球晶的形态与生成条件,发现在原始样品熔点附近或高于原始熔点以上温度结晶,主要生成暗、亮与带正环的负光性放射状球晶;熔点以下至195℃主要生成正放射状球晶;在较宽的温度范围内可生成混合光性放射状球晶,与少量的六瓣、两瓣、不对称四瓣形三种异常光性球晶;181℃以下主要生成正环状球晶.
In this paper, the morphology and formation conditions of nylon 1010 spherulite during isothermal crystallization were studied by polarized light microscope. It was found that the crystallinity of the spherulite nylon 1010 near the original melting point or higher than the original melting point resulted in the formation of dark, bright and positively- ; Below the melting point to 195 ° C mainly produces a positive radial spherulite; in a wide temperature range can be generated mixed spheroidal radial spherulites, and a small amount of six, two, asymmetric four-lobe three abnormal optical spherulites 181 ℃ below the main generation is the main ring spherulites.
