本文通过硫化钠直接中和还原苦味酸，采用盐酸单一加料法和自主研制的F-1晶型控制剂，制得球形DDNP，平均粒径大于350μm，其100目筛上物达到95%以上，散装密度在0.70～0.90g/cm3范围可控，耐压性大于400MPa，流散性好，生产过程中没有细小结晶和爆炸性粉尘，产品得率比传统的DDNP制备工艺提高2～3%，生产过程不需漂洗细小结晶工序，同时采用部分母液循环的办法，单位产品的工艺用水量为30～35kg/kg（DDNP），目前已实现工业化生产。 In order to obtain spherical DDNP （Diazodinitrophenol）spherical DDNP were prepared by deoxidating picric acid with Na2S .single feeding hydrochloric acid and F-1 additive., No.100 sieve number of particles has greater than 95%, the average grain diameter of it is over 350μm, and resistance to pressure of it reaches 40 MPa. Moreover the bulk specific weight are controllabled in the range of 0.75~0.90g/cm3. fluxion property of DDNP is good. There are no fine crystals and explosive dust in production process. Compared to traditional DDNP production techniques, product yield increases 2-3%, and processing use of water is 30-50kg per kilogram of DDNP. At present, the industrial production of the spherical DDNP has been realized. |

| Spherical DDNP is obtained through reducing picric acid with sodium sulfide and through the employment of single feeding of hydrochloric acid and self-developed F-1 crystal shape controller. Said product has an average pore size more than 350 micrometers with more than 95% is left above the sieve, a controllable bulk density between 0.70-0.90g/cm3, a baroduricity more than 400MPa, a good mobility. In the present produce process, no fine crystal or explosive dust is produced, and thus eliminate the need to wash away the fine crystals. The yield is 2-3% higher than the traditional method,and through the cycle use of mother liquid the water need for each product unit is 30-35kg/kg. It has found application in industrial scale production.把你的一些词改成了我认为是专业一点的，你再检查一下。楼主原来的英语是用软件翻译的吗？ |
