Magwiridwe

WOKUTHANDIZAndi organophosphoric acid dzimbiri inhibitor. Imatha kusungunuka ndi Fe, Cu, ndi Zn ions kuti ipange makina okhazikika a chelating.WOKUTHANDIZA imawonetsa kukula kwakukulu ndi dzimbiri poletsa kutentha pansi pa 250 ℃. WOKUTHANDIZAimakhala ndi bata lokhazikika pamtengo wochepa kwambiri wa pH, yovuta kuthiridwa ndi hydrolyzed, ndipo imakhala yovuta kuwola pansi pakuwala wamba ndi kutentha. Kulekerera kwa asidi / alkali ndi klorini makutidwe ndi okosijeni kuli bwino kuposa kwamagulu ena amchere (mchere).WOKUTHANDIZAamatha kuthana ndi ayoni yazitsulo m'madzi kuti apange ma hexa-element chelating complex, makamaka calcium ion. Chifukwa chake,WOKUTHANDIZAali ndi antiscale yabwino komanso yowoneka bwino. Ikamangidwa pamodzi ndi mankhwala ena amadzimadzi, imawoneka bwino. Mkhalidwe wolimba waWOKUTHANDIZAndi ufa wonyezimira, woyenera kugwiritsidwa ntchito m'nyengo yozizira komanso yozizira. Chifukwa choyera kwambiri, itha kugwiritsidwa ntchito ngati yoyeretsera m'magetsi komanso ngati zowonjezera m'mankhwala amtsiku ndi tsiku.

Kugwiritsa ntchito

WOKUTHANDIZA amagwiritsidwa ntchito ngati sikelo ndi dzimbiri chopinga pozungulira madzi ozizira, malo amafuta ndi zotentha zochepa pamagetsi monga magetsi, mafakitale amagetsi, zitsulo, feteleza, ndi zina zotero. WOKUTHANDIZAimagwiritsidwa ntchito ngati chotsukira chachitsulo komanso chosapanga dzimbiri. Makampani odaya,WOKUTHANDIZAimagwiritsidwa ntchito ngati chikhazikitso cha peroxide komanso wothandizira utoto; Mu non-cyanide electroplating,WOKUTHANDIZAamagwiritsidwa ntchito ngati wonyenga. Mlingo wa 1-10mg / L umasankhidwa ngati scale inhibitor, 10-50mg / L ngati dzimbiri choletsa, ndi 1000-2000mg / L ngati chotsukira. Kawirikawiri,WOKUTHANDIZA imagwiritsidwa ntchito limodzi ndi polycarboxylic acid.
