用途：是一種廣譜高效的工業(yè)殺菌劑，用來防止細(xì)菌和藻類在造紙、工業(yè)循環(huán)冷卻水、金屬加工用潤滑油、紙漿、木材、涂料和膠合板中的生長繁殖，同時可做粘泥控制劑，廣泛用于造紙廠紙漿和循環(huán)冷卻水系統(tǒng)。作為廣譜高效的殺生劑，能迅速穿透微生物的細(xì)胞膜，并作用于一定的蛋白集團(tuán)，使細(xì)胞的正常氧化還原中止，從而引起細(xì)胞死亡。同時，它的分支還可以選擇性的溴化或氧化微生物的特殊酶代謝物，最終導(dǎo)致微生物死亡。本品具有良好的剝離性能，使用時無泡沫，液體產(chǎn)品與水可任意比互溶，低毒。

DBNPA (2.2-Dibromo -3 - Cyanide (Nitrile) C-based amide):
Molecular formula: C3H2Br2N2O
Molecular weight:242
CAS NO.:10222-01-2
Usage: biocides in broad spectrum. It is widely used in industrial circulating water system, large air-condition and the large center of sewage treatment to eliminate microorganism and alga and shuck off clay. It is also used in the process of paper making to prevent reducing quality of paper by generation of microorganism . It is suitable for metal cutting of cooling liquor, recovery system of oil, latex and ply-woods as anti-spy biocides. It has following advantages :Easy to handle .No unusual oxidation hazards .Similar performance and safety in paper and oilfield applications .Used for slime control in the wet-end of the paper mill and performs exceptionally well against slime-forming bacteria. DBNPA has exhibited outstanding efficacy against in bio-films and against a broad spectrum of bacteria, fungus and yeasts. Coating and Fillers
DBNPA series products are used in the short-term preservation of coatings and coating additives such as latex, starch and mineral slurries. DBNPA is a fast-acting/quick-kill biocide that is broad-spectrum, and does not contain or release formaldehyde.
