红河磷肥厂半水-二水物法磷酸装置生产小结

These principles have been successfully applied in the design of the HDH type bumer for hydrogen-rich fuel gases .

此原则已成功地应用于HDH型高氢燃料气燃烧器的设计中。

Results : The HDH could reduce obviously the blood viscosity , inhibit platelet aggregation and reduce thrombosis of the rabbits , restrain experimental arthritis of rats and lighten capillary vessel permeability of mice .

结果：红桃消肿合剂明显降低血瘀家兔血黏度、抑制血小板聚集和体外血栓形成，抑制大鼠足肿胀和小鼠毛细血管通透性。

By controlling the processing parameters , loose density of the powders and adding element Nd in proper quantities , low cost HDH titanium alloy powders can be used instead of expensive sphere powders in some conditions .

通过合理控制松装密度、添加适量稀土元素以及优化工艺参数，在特定的应用需求下，低成本HDH钛合金粉末能够代替昂贵的球形粉末在激光快速成形技术中使用。

The main way of producing Titanium powders is HDH , but great shortcoming of HDH has appeared because of the high price influence of titanium sponge , while MHR has gradually shown the advantages due to its low cost .

目前国内主要采用的是HDH法，但其受海绵钛的影响具有很大的局限，而采用MHR法由于消耗的成本低廉。因而该法显现出日益明显的优越性。

Through repeated research and innovation , Honghe Phosphate Fertilizer Factory has stabilized the daily production volume of the 60 kt / a HDH process phosphoric acid plant at 5 000-5 500 tons ( P2O5 ) . process indexes basically meeting design requirements .

红河磷肥厂反复摸索、整改，使60kt/a半水&二水物法磷酸装置的月产量稳定在5000～5500t（P2O5计），各项工艺指标已基本达到设计要求。
