In actuality it swells the skin , making the nerves temporarily " shocked " so it will stop the itching short term 实际上,氨水会让皮肤鼓起,让神经细胞暂时“震惊” ,从而氨水能短期的停止瘙痒。
It contains suspended solids , dissolved colloidal organic matter and nutrients such as phosphates and ammonia and possibly also metals 它包含悬浮固体,溶解胶质有机物以及像磷酸盐和氨水之类的营养物
Put some yeast on the stains and wash with water . it will be more effective if a little bit of ammonia solution is added during washing 可用酵母粉撒在污渍上,滴水洗濯,洗濯时加入少许氨水溶液效果更佳。

On the other hand , when ph value and coating temperature decreased and the nh4oh dosage increased , the stability of the bath was increased 降低反应的温度、提高氨水用量、降低ph值可使镀液稳定性大为提高。
The new technology also fixes hydrazine hydrate inside the fuel tank to ensure its safe use as a fuel , resulting in no co2 emissions at all 新技术在油箱中加入联氨水化合物,保证燃料使用安全及完全没有co2废气排放。
Water - tube boilers and auxiliary installations - requirements for flue gas denox - systems using liquified pressurized ammonia and ammonia water solution 水管锅炉和辅助设备.使用液压氨和氨水溶液的废气denox系统的要求
And the chemical bath for deposition of sns thin films was constitute of triethanolamine sncl2 2h2o , nh4cl . nh4oh and triethanolamine 以三乙醇胺、硫代乙酰胺、氯化亚锡、氨水、氯化铵为反应物,采用常规化学浴制备sns薄膜。
