Nyob rau hauv txoj kev loj hlob ntawm fungicides, cov tebchaw tshiab tshwm sim txhua xyoo, thiab cov nyhuv bactericidal ntawm cov tebchaw tshiab kuj pom tseeb heev.tshwm sim.Niaj hnub no, kuv yuav qhia ib tug heev "tshwj xeeb" fungicide.Nws tau siv nyob rau hauv kev ua lag luam tau ntau xyoo, thiab nws tseem muaj cov kab mob bactericidal zoo heev thiab tsis muaj zog.Nws yog "chlorobromoisocyanuric acid", thiab cov yam ntxwv thiab kev siv tshuab ntawm cov khoom no yuav qhia tshwj xeeb hauv qab no.
Cov ntaub ntawv tseem ceeb ntawm chlorobromoisocyanuric acid
Chlorobromoisocyanurickua qaub, hu ua "Xiaobenling", yog cov tshuaj tua kab mob oxidizing siv dav hauv cov tuam txhab dej, cov pas dej da dej, chaw kho mob, chaw ua haujlwm huv, kev ua liaj ua teb, tsiaj txhu thiab cov khoom hauv dej, thiab lwm yam. Hauv kev ua liaj ua teb, 50% chlorobromoisocyanuric acid feem ntau yog siv.Raws li kev ua haujlwm siab, dav-spectrum, tshiab systemic fungicide, nws tuaj yeem tua ntau yam kab mob, algae, fungi thiab kab mob.
Cov yam ntxwv ntawm chlorobromoisocyanuric acid
Chlorobromoisocyanuric acid tuaj yeem maj mam tso Cl thiab Br thaum txau rau saum npoo ntawm cov qoob loo, tsim cov tshuaj hypochlorous acid (HOCl) thiab bromic acid (HOBr), uas muaj zog tua, kev nqus dej thiab tiv thaiv kab mob qoob loo, fungi thiab kab mob, yog li nws muaj zog tua cov kab mob thiab cov kab mob, thiab tseem muaj zog tua cov kab mob ntawm cov qoob loo, thiab cov nqi ua tau zoo heev.Nws muaj qhov zoo ntawm cov tshuaj lom neeg tsawg, tsis muaj qhov seem, thiab tsis tshua muaj kev tiv thaiv rau kev siv mus ntev rau cov qoob loo, uas yog qhov tsim nyog rau cov kev xav tau ntawm cov zaub tsis muaj kuab paug.Nyob rau tib lub sijhawm, nws tuaj yeem kho cov kab mob sai sai los ntawm cov kab mob ntawm cov nroj tsuag, tsis muaj kev cuam tshuam rau cov waxy txheej ntawm cov nroj tsuag, thiab nws muaj kev nyab xeeb rau cov nroj tsuag.
