异噻唑啉酮(Isothiazolinones)性能与用途

异噻唑啉酮主要由5-氯-2-甲基-4-异噻唑啉-3-酮(CMI)和 2-甲基-4-异噻唑啉-3-酮(MI)组成。异噻唑啉酮是通过断开细菌和藻类蛋白质的键而起杀生作用的。异噻唑啉酮与微生物接触后,能迅速地不可逆地抑制其生长,从而导致微生物细胞的死亡,故对常见细菌、真菌、藻类等具有很强的抑制和杀灭作用。杀生效率高,降解性好,具有不产生残留、操作安全、配伍性好、稳定性强、使用成本低等特点。能与氯及大多数阴、阳离子及非离子表面活性剂相混溶。高剂量时,异噻唑啉酮对生物粘泥剥离有显著效果。

异噻唑啉酮是一种广谱、高效、低毒、非氧化性杀生剂。广泛运用于油田、造纸、农药、切削油、皮革、油墨、染料、制革等行业。

异噻唑啉酮(Isothiazolinones)使用方法

异噻唑啉酮2类产品作粘泥剥离剂时,投加浓度150-300mg/l;作杀菌剂时,每隔3-7天投加一次,投加剂量80~100mg/L。能与氯气等氧化型杀菌剂同时使用,不能用于含硫化物的冷却水系统。异噻唑啉酮与季铵盐复合使用效果较佳。

异噻唑啉酮做工业杀菌防霉剂使用时,一般浓度为0.05-0.4%。

异噻唑啉酮(Isothiazolinones)包装与贮存

异噻唑啉酮用塑料桶包装,每桶25kg或根据用户要求确定;贮于室内阴凉处,贮存期十个月。

异噻唑啉酮(Isothiazolinones)安全防护

异噻唑啉酮对皮肤有腐蚀性,会造成皮肤灼伤,引起过敏性皮炎,影响会持续数小时。严禁接触皮肤和眼睛,操作时应配备防护眼镜和胶手套等劳保用品,如接触皮肤,立即脱去被污染的衣服和鞋子,用大量清水冲洗至少15分钟,患处涂抹醋酸尿素软膏或烫伤膏,并立即就医。

Properties:

Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation.

Isothiazolinones can mix with chlorine and most cation, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent.

Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity and non-oxidative, it is the ideal biocidal in industrial circulating cool water system and in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent and cosmetics etc..

Usage:

When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred, when used as boicide, the dosage of 80-100mg/L is preferred, and charges every 3-7 days. No used together with oxidative fungicidal such as chlorine, and no used in cooling water system containing sulfur. When used together with quaternary amine, the effect will be better. When used as industrial fungicide, the dosage of 0.05-0.4% is preferred.
