1、性能与用途 Performance and application 

本品是一种季胺盐型阳离子表面活性剂，属于非氧化性杀菌剂，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，在水中能改变细胞的性质，杀伤细胞原生质膜，并与蛋白质反应，使细胞死亡，同时本品具有一定的去油、除臭能力和缓蚀作用。该产品毒性小，无积累性毒性，易溶于水，并且不受水硬度影响，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。 

This product is a quaternary ammonium salt type cationic surfactant, belonging to the non-oxidizing bactericide. With broad-spectrum, highly effective bactericidal and algae-killing capacity, it can effectively control the propagations of bacteria & algae and slime growth, change the characters of cells in water, damage its protoplast membrane and react with protein to extinguish cells. At the same time, the product has certain capabilities of degreasing, deodorization and corrosion inhibition. With minor toxicity, non-accumulation of toxic, soluble in water and non-affection of water hardness, it is widely used in cooling water systems of petroleum, chemical, electric power, textile and other industries, to control breeding of bacteria and algae in circulating cooling water system, and it is particularly effective in exterminating sulfate-reducing bacteria. 

本品广泛运用于循环冷却水、油田、造纸、农药、切削油、皮革、油墨、梁料、制革等行业。 

This product is widely used in circulating cooling water, oilfield, paper, and pesticide, cutting oil, leather, printing ink, dyestuffs, and tanning industry.

3、使用方法 Usage 

本品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。可与其它杀菌剂配合使用，可起到增效作用。投加本品后循环水因剥离而出现污物，应及时滤除或捞出，以免泡沫消失后沉积。 

When used as non-oxidative bactericidal algicide, the dosage is generally 50-100mg / L; when used as slime stripping agent, the dosage is 200-300mg / L, and proper amount of organic silicone defoamer can be added if necessary. The product can be used in conjunction with other fungicides, which could reach a synergism effect. After adding the materials in the circulating water, dirt spin-off may arise, which should be timely filtered or removed to avoid deposition after the disappearance of the foams. 

4、 包装与贮存 Packing and storage 

使用塑料桶包装，每桶25kg或200kg。贮于室内阴凉通风处，贮存期为二十四个月。 

Pack in 25kg or 200kg plastic drum. Be stored for 24 months in room ventilated and ventilated place.
