採用氟塑料f4整體冷壓成型及熱熔加工等先進技術製造,使內襯層無縫搭接且與外層金屬管壁緊密粘接,在允許工作狀態下能夠保持同步變形,從而提高了襯里層在相對高溫高真空度的工況下的使用壽命,杜絕了一般襯氟管在冷熱交替,及負壓的條件下使用易產生襯塑層鼓癟阻塞流道及塑料拉裂的問題,是現代化工企業在輸送強腐蝕強氧化介質理想的選擇。Several flux systems have been studied, especially about the mixed flux system. we found that the use of mixed systems such as k2co3 - b2o3 - naf had greatly decreased the viscosity of the melt, decreased the saturation point and improved the growth quality of the crystal. the flux system naf - b2o3 is favour of decreasing the volatilization and the saturation point of the melt
對kabo晶體的幾種助溶劑體系尤其對復合助溶劑體系進行了研究,我們發現復合助溶劑體系如: k _ 2co _ 3 - b _ 2o _ 3 - naf有利於減小熔體粘度,降低飽和點溫度,改善晶體的生長性能; naf - b _ 2o _ 3體系有利於降低熔體揮發性和飽和點溫度。Among the properties which do not show a leveling-off are the viscosities of solutions and melts.
溶液和熔體的粘度等性能曲線並不呈現平坦。There are kinds of polycarbonate ( pc ), it is worth a kind of engineering materials for bisphenol a - polycarbonate, its main shortcoming are crazed easily, high molten body viscidity and difficult forming process characteristic, so many kinds of modified methods are brought into effect for it
摘要聚碳酸酯品種較多,作為工程材料最有價值的是雙酚a型聚碳酸酯,其主要缺點是易開裂,熔體粘度高,成型加工較困難,為此進行了各種改性方法。During the laser sintering, due to the large liquid phase viscosity and surface tension, the balling effect occurred when the molten did not wet the solid metal particle and the underlying substrate
實驗發現,在液相粘度較高、表面張力大,熔體材料不浸潤固相顆粒和基板等因素的影響下,燒結過程中出現了球化現象。But, the melt viscosity of the sbs and sebs elastomers is highly affected by the shear rate inside the barrel but it is not sensitive to the temperature inside the barrel
