| 2. | And the spherulite growth rate of phbv is studied and the factors , which influence the growth rate and the formula of spherulite growth rate , were discussed
并通过对phbv球晶生长速率的测定，对结。晶生长的速度方程及影响因素做出修正。 |
| 3. | Our products include various types of biodegradable shopping bags , garbage bags , t - shirt vest bags and dead body bags , etc made from pla enbiomat phb mater - bi pha phbv etc
等全生物分解材料做成的各种类包装袋购物袋垃圾袋背心袋挂衣袋堆肥袋和包尸袋等。 |
| 4. | It is the first time to get phbv fiber by melt spinning in china . and the changes of fiber crystallization structure and orientation structure under force were studied
并在国内首次通过熔融法制备了phbv纤维，首次论证了纤维结晶结构的变化及其在外力作用下取向结构的变化。 |
| 5. | On the surface of phbv spherulite , some concentric ring like patterns will occur . based on the procedure of the formation of ring - like patterns , the possible mechanism is given
在球晶的表面出现有同心圆环状条纹，经实验验证为表面的不平整所导致，形成机理主要可能是结晶过程中的体积收缩。 |
| 6. | This change makes the processing difficult . it is found that phbv ( poly ( hydroxybutyrate - co - valerate ) will still thermal degrade at the temperature much more lower than the acute thermal degradation temperature
通过研究发现， phbv (聚羟基丁酸-羟基戊酸酯)在其发生剧烈快速热降解的温度以下仍然有热降解行为的发生。 |
| 7. | But it is mainly dependant on the physical parameters such as volume shrinkage . and when phbv crystallized , the hv content will be segregated , it will be accelerated when crystallization temperature is increased
在结晶过程中， phbv二元共晶中hv (羟基戊酸)组分会受到排斥，结晶温度的升高会导致hv组分分凝现象的加剧。 |
| 8. | A reasonable mechanism of the concentric ring like patterns on the surface of phbv spherulite was given first . the segregation of hv content between cystal and amorphous parts was observed and the phenomena caused were discussed
首次对phbv球晶表面观察到的同心圆环条纹的成因作了合理解释，揭开了这一现象形成的本质。 |
| 9. | The sgr ( spherulite growth rate ) of phbv is related to crystallization temperature . with the increase of temperature , sgr increase first then decrease . some sample ' s sgr will increase again at high temperature area
Phbv的球晶生长速度与时间无关，随温度的升高有先上升后下降的趋势，部分样品在最后球晶速度会再次上升。 |
| 10. | Dsc test shows , that if the sample crystallized at a low temperature , the result has a small peek , if it crystallized at a higher temperature , then the peek will divide into two peeks . it is believed related to the segregation of hv content
Phbv在较低温度下结晶所得样品的dsc图谱在低温区的次峰在较高结晶温度时分裂成两个次峰，分析是由于结晶温度升高时的分凝现象所致。 |
