異噻唑啉酮主要由5-氯-2-甲基-4-異噻唑啉-3-酮(CMI)和 2-甲基-4-異噻唑啉-3-酮(MI)組成。異噻唑啉酮是通過斷開細(xì)菌和藻類蛋白質(zhì)的鍵而起殺生作用的。異噻唑啉酮與微生物接觸后，能迅速地不可逆地抑制其生長，從而導(dǎo)致微生物細(xì)胞的死亡，故對常見細(xì)菌、真菌、藻類等具有很強(qiáng)的抑制和殺滅作用。殺生效率高，降解性好，具有不產(chǎn)生殘留、操作安全、配伍性好、穩(wěn)定性強(qiáng)、使用成本低等特點。能與氯及大多數(shù)陰、陽離子及非離子表面活性劑相混溶。高劑量時，異噻唑啉酮對生物粘泥剝離有顯著效果。
異噻唑啉酮是一種廣譜、高效、低毒、非氧化性殺生劑。廣泛運用于油田、造紙、農(nóng)藥、切削油、皮革、油墨、染料、制革等行業(yè)。

Isothiazolinones
【CAS】26172-55-4, 2682-20-4 Molecular weight: 115.16
Properties: Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking the bond between bacteria algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong inhibition biocidal effects ondinary bacteria, fungi alga, 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 most cation, anion, 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 non-oxidative, it is the ideal biocidal in industrial circulating cool water system in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent cosmetics etc..
Specification: Notes: 2%, 4% 8% any concentration can be supplied on demands.
