ammonia nitrate
    The study on the K\ NH4+ II NO3~-H2O showed that the graph contains the five crystal sections , which included the potassium nitrate, the ammonium nitrate, the potassium nitrate and solid solution, the ammonia nitrate and solid solution ,and the solid solution crystal sections.
    对K~+、NH_4~+‖NO_3~--H_2O三元体系相平衡的研究表明,该体系存在五个结晶区:硝酸钾和硝酸铵结晶区、硝酸钾与硝酸钾铵结晶的共晶区、硝酸铵与硝酸钾铵结晶的共晶区,以及硝酸钾铵固溶体结晶区。
    Advanced Process of Porous Ammonia Nitrate and Revamp of Present Domestic Ammonia Nitrate Plant
    国外新的多孔硝酸铵生产工艺与国内硝酸铵装置的改造
    Ammonia Nitrate Air Dried System
    硝酸铵气流干燥系统
    The best media obtained from the orthogonal test in this culture conditions are as follows:corn starch 2%,sucrose 1.5%,peptone 1%,ammonia nitrate 0.2% and a small amounts of mineral salts.
    通过正交试验获得适于产植酸酶的液体培养基的配方为:玉米淀粉2%,蔗糖1.5%,蛋白胨1%,硝酸铵0.2%以及少许无机盐。
    The optimum temperature and pH for mycelial growth was 25~28℃ and pH 7~9, respectively. The fungus grows better in Arabic gum powder as carbon source and in ammonia nitrate as nitrogen source.
    该菌生长最适温度为 2 5~ 2 8℃ ,pH值为 7~ 9,它能有效地利用各种碳源 ,但以阿拉伯树胶粉最好 ,氮源以硝酸铵最适。
    In the production of potassium nitrate by using the method of decomposing ammonia nitrate and potassium chloride in cycle, based on the characteristics of the solution, spiral plate heat exchanger was applied to the process of cooling and crystallizing potassium nitrate solution. This exchanger has the advantages of resisting foul, high film coefficient, low energy consumption, high production ability, small volume and convenience in operation.
    在硝酸铵与氯化钾复分解循环法生产硝酸钾工艺中,根据溶液物料特性,设计并采用螺旋板换热器应用于硝酸钾溶液的冷却结晶工艺,生产硝酸钾,具有不结垢,传热系数高,能耗低,生产能力大,体积小,操作方便等优点。
