1、性能Performance
在溫度200℃下，具有優良阻垢作用，化學性能穩定，不易水解，其性能優於無機聚磷酸鹽，濃度較高時，有良好的緩蝕效果，且本身無毒，*。
ATMP has good anti-scale effect under 200℃. It has good chemical stability and is hard to be hydrolyzed. It has a better performance than inorganic polyphosphates. At high concentration, it has good corrosion inhibition, and it is innocuous itself and has none pollution to environment.
2、用途Application
廣泛用于電力、化工、化肥行業循環水處理的緩蝕、阻垢，也可作為硬度大、礦化度高、水質條件惡劣的油管用水及油田注水的水處理藥劑。
ATMP is widely used for corrosion and scale inhibitions in circulating water treatment in fields of power plant, chemical industry and fertilizer. It can also be used as water treatment agent in water supply for oil pipes and oilfield injection water, which are featured in high hardness, high mineralization and other poor water conditions.

4、使用方法 Usage
本品可與無機磷，共聚物等復使用，其中ATMP用量約占5～15%，單獨使用時，一般投加量2～5ppm，在冷卻水中使用時，Ca硬限制在400ppm（以CaCO3計）為好。
ATMP can be applied in compound use with inorganic phosphorus and copolymers, among which the dosage of ATMP is 5~15%; when used alone, the dosage 2~5 ppm is preferred; when used in cooling water, the content of Ca （as CaCO3 ） should be preferably limited to 400ppm.
