Description

即ち、本発明に係る工業用抗菌方法は、水系のスライムコントロール及び防腐を行う工業用抗菌方法であって、前記水系に、スルファミン酸及び／若しくはスルファミン酸塩を添加する工程と、前記スルファミン酸及び／若しくはスルファミン酸塩とは別に、前記水系に、アンモニウム塩と活性塩素源との反応生成物を、有効塩素濃度が１〜１００ｍｇ／Ｌになるよう添加する工程と、を有し、前記反応生成物を添加する工程は、前記スルファミン酸及び／若しくはスルファミン酸塩を添加する工程の後、又は、前記スルファミン酸及び／若しくはスルファミン酸塩を添加する工程と同時に行う。
この工業用抗菌方法では、前記反応生成物及び前記スルファミン酸（塩）の添加量を、モル比で、反応生成物（Ｃｌ_２換算値）：スルファミン酸及びその塩（合計値）＝５：９５〜９５：５とすることができる。
また、前記反応生成物としては、臭化アンモニウムと次亜塩素酸ナトリウムとの反応生成物を用いることができる。
更に、前記反応生成物は、スルファミン酸及び／若しくはスルファミン酸塩を添加した後で、又は、スルファミン酸及び／若しくはスルファミン酸塩と共に、前記水系に添加することができる。 That is, the industrial antibacterial method according to the present invention is an industrial antibacterial method that performs water-based slime control and preserving, the step of adding sulfamic acid and / or sulfamate to the aqueous system, and the sulfamic acid and And / or adding a reaction product of an ammonium salt and an active chlorine source to the aqueous system separately from the sulfamate so that the effective chlorine concentration is 1 to 100 mg / L. The step of adding the product is performed after the step of adding the sulfamic acid and / or sulfamic acid salt or simultaneously with the step of adding the sulfamic acid and / or sulfamic acid salt .
In this industrial antibacterial method, the addition amount of the reaction product and the sulfamic acid (salt) is expressed in molar ratio as follows: reaction product (Cl ₂ converted value): sulfamic acid and its salt (total value) = 5: 95 -95: 5.
As the pre-Symbol reaction product can be used a reaction product of ammonium bromide and sodium hypochlorite.
Further, the said reaction product, after the addition of sulfamic acid and / or sulfamic acid salts, or can be sulphamic acid, and / or with sulfamic acid salt, is added to the aqueous system.
