Kuonekwa: Kuumbwa kwechigadzirwa chemvura 30% w/w Yakanyungudutswa mu1,2 propylene glycol 4.4 '-dichloro2 -hydroxydiphenyl ether iine viscous zvishoma, isina ruvara kusvika kune brown fluid.(Iyo yakasvibirira yakasimba ichena, yakachena secrystal flake.)
Hupenyu hwesherufu: Dichlosan ine hupenyu hwesherufu hweanosvika makore maviri mukurongedza kwayo kwekutanga.
Zvimiro: Tafura inotevera inoronga zvimwe zvezvinhu zvemuviri.Aya ndiwo maitiro akajairika uye haasi ese maitiro anogara achitariswa.Hazvirevi kuti zvinoumba chikamu chezvakatemwa zvechigadzirwa.Mamiriro emhinduro ndeaya anotevera:

Mirayiridzo:
Sezvo dichlosan ine yakaderera solubility mumvura, inofanira kunyungudutswa mune yakaomeswa surfactants pasi pekupisa mamiriro kana zvichidikanwa.Dzivisa kuratidzwa kune tembiricha>150°C.Nokudaro, zvinokurudzirwa kuwedzera kushambidza poda mushure mekuoma mushongwe yekupfapfaidza.
Dichlosan haina kugadzikana mumagadzirirwo ane TAED reactive oxygen bleach.Equipment kuchenesa mirayiridzo:
Zvishandiso zvinoshandiswa kugadzira zvigadzirwa zvine diclosan zvinogona kucheneswa zviri nyore uchishandisa concentrated surfactants uye wozosukurudzwa nemvura inopisa kudzivirira kunaya kweDCPP.
Dichlosan inotengeswa sebiocidal inoshanda chinhu.Chengetedzo:
Zvichienderana neruzivo rwedu mumakore uye rumwe ruzivo rwuripo kwatiri, diclosan haikonzere zvinokuvadza hutano chero bedzi ichishandiswa nemazvo, kutariswa kwakakodzera kunobhadharwa kune dziviriro dzinodiwa kubata kemikari, uye ruzivo uye kurudziro inopiwa mune yedu. kuchengetedza data mapepa anoteverwa.
Application:
Inogona kushandiswa se antibacterial uye antiseptic muminda yekurapa kwemunhu kuchengetedza zvigadzirwa kana cosmetics.Buccal disinfectant zvigadzirwa.
