一、性能与用途
1227是一种阳离子表面活性剂，属非氧化性杀菌剂，具有广谱、高效的杀菌灭藻能力，能有效地控制水中菌藻繁殖和粘泥生长，并具有良好的粘泥剥离作用和一定的分散、渗透作用，同时具有一定的去油、除臭能力和缓蚀作用。
1227毒性小，无积累性毒性，并易溶于水，并不受水硬度影响，因此广泛应用于石油、化工、电力、纺织等行业的循环冷却水系统中，用以控制循环冷却水系统菌藻滋生，对杀灭硫酸盐还原菌有特效。
1227可作为纺织印染行业的杀菌防霉剂及柔软剂、抗静电剂、乳化剂、调理剂等。

三、使用方法1227作非氧化性杀菌灭藻剂，一般投加剂量为50-100mg/L；作粘泥剥离剂，使用量为200-300mg/L，需要时可投加适量有机硅类消泡剂。1227可与其它杀菌剂，例如异噻唑啉酮、戊二醛、二硫氰基甲烷等配合使用，可起到增效作用，但不能与氯酚类药剂共同使用。投加1227后循环水中因剥离而出现污物，应及时滤除或捞出，以免泡沫消失后沉积。
1227切勿与阴离子表面活性剂混用。
四、安全与防护1227略有杏仁味，对皮肤无明显刺激，接触皮肤时，用水冲洗即可。
五、包装与贮存：1227塑料桶包装，每桶25kg或200 kg。贮于室内阴凉通风处，贮存期为二年。

Usage:
As nonoxidizing boicide, dosage of 50-100mg/L is preferred; as sludge remover, 200-300mg/L is preferred, adequate organosilyl antifoaming agent should be added for this purpose. This product can be used together with other fungicidal such as isothiazolinones, glutaraldegyde, dithionitrile methane for synergism, but cannot be used together with chlorophenols. If sewage is appeared after thrown of this product in circulating cool water, the sewage should be filtered or blown off in time to prevent their deposit in bottom of collecting tank after froth disappearance.
No blending with anion surfactant.
Package and Storage:
25kg or 200kg in plastic barrel, or confirmed by clients. Storage for two year in room shady and dry place.
Safety Protection:
A little smell of almond, no visible stimulation to skin. When contacted, flush with water.
