Scale inhibitor

Scale inhibitor: imatha kumwaza mchere wosasungunuka m'madzi, kuteteza kapena kusokoneza mvula ndi makulitsidwe a mchere wosasungunuka pamwamba pa zitsulo, ndikukhalabe ndi kutentha kwabwino kwa zida zachitsulo. Zomwe zimapangidwazo zimakonzedwa potenga utomoni wa epoxy ndi utomoni weniweni wa amino ngati zida zoyambira, ndikuwonjezera kuchuluka koyenera kwa anti- dzimbiri ndi zowonjezera zotsutsana ndi dzimbiri kuti apange chigawo chimodzi. Ili ndi chitetezo chabwino kwambiri, chosasunthika, kukana dzimbiri, kukana kwabwino, kutsekemera kwamafuta, kukana kwambiri kwa asidi ofooka, alkali wamphamvu, zosungunulira za organic ndi katundu wina, zomatira zolimba, zowala, zosinthika, filimu yowoneka bwino komanso yovuta.

Kupinda kosinthira makina

Kuchokera ku makina a scale inhibitor, mphamvu yolepheretsa kukula kwa scale inhibitor ikhoza kugawidwa mu chelation, dispersion ndi lattice kupotoza. Pakuyesa kwa labotale, kubalalitsidwa ndi njira yolumikizirana, ndipo kupotoza kwa lattice ndiko njira yothetsera kubalalitsidwa.

Makhalidwe ogwirira ntchito a High Effective Reverse Osmosis Scale Inhibitor

Sikoyenera kuwonjezera asidi owonjezera, omwe amatha kupewa kuwonongeka kwa zida ndi zinthu za acidic.

2 chelating zotsatira ndi khola, zingalepheretse chitsulo, manganese ndi ayoni zitsulo zina pa nembanemba chubu kupanga dothi.

Ndi oyenera mitundu yonse ya nembanemba chubu zipangizo.

Kuwongolera kwachuma kwambiri kumatha kutheka ndi mlingo wocheperako komanso mtengo wotsika.

Itha kuchepetsa kuyeretsa kwa nembanemba ndikutalikitsa moyo wautumiki wa membrane.

Kupinda chelation

Chelation ndi njira yomwe ion yapakati imamangiriza ku ma atomu awiri kapena angapo ogwirizana a polydentate ligand yomweyo. Chifukwa cha chelation, makulitsidwe ma cations (monga Ca2 +, Mg2 +) amachita ndi chelating agents kuti apange chelates okhazikika, omwe amawalepheretsa kukhudzana ndi ma anions owonjezera (monga CO32 -, SO42 -, PO43 - ndi sio32 -), motero kuchepetsa kwambiri kuthekera kwa makulitsidwe. Chelation ndi stoichiometric, mwachitsanzo, kumangiriza kwa molekyulu ya EDTA ku ion yachitsulo ya divalent.

Kuthekera kwa chelating agents kumatha kuwonetsedwa ndi mtengo wa chelating wa calcium. Kawirikawiri, mankhwala opangira madzi amalonda (gawo lalikulu la zigawo zotsatirazi zonse ndi 50%, zowerengedwa ndi CaCO3): aminotrimethylphosphonic acid (ATMP) - 300mg / g; diethylenetriamine pentamethylene phosphonic acid (dtpmp) - 450mg / g; ethylenediamine tetraacetic acid (EDTA) - 15om / g; hydroxyethyl diphosphonic acid (HEDP) - 45 OM. Mwa kuyankhula kwina, 1mg chelating wothandizira akhoza kuchetetsa calcium carbonate scale yocheperapo 0.5mg. Ngati ma ion a calcium ndi magnesium okhala ndi kuuma kwathunthu kwa smm0fl akuyenera kukhazikika m'madzi ozungulira, cholumikizira chofunikira ndi 1000m / L, chomwe ndi chachuma komanso chothandiza. Chifukwa chake, chopereka cha scale inhibitor chelation ndi gawo laling'ono chabe. Komabe, chelation of scale inhibitors imagwira ntchito yofunika kwambiri m'madzi apakati komanso otsika.

Kupiringa kubalalikana

Chifukwa cha kubalalitsidwa ndi kuteteza kukhudzana ndi agglomeration wa okusayidi lonse particles, motero kuteteza kukula kwa okusayidi lonse. Tinthu tating'onoting'ono ta calcium ndi magnesium ion, mazana a ma molekyulu a CaCO3 ndi MgCO3, fumbi, matope kapena zinthu zina zosasungunuka m'madzi. Dispersant ndi polima yokhala ndi kulemera kwina kwa maselo (kapena digiri ya polymerization), ndipo kubalalitsidwa kwake kumagwirizana kwambiri ndi kulemera kwa maselo (kapena digiri ya polymerization). Ngati digiri ya polymerization ndi otsika kwambiri, chiwerengero cha particles adsorbed ndi omwazika ndi yaing'ono, ndi kupezeka dzuwa ndi otsika; ngati digiri ya polymerization kwambiri, chiwerengero cha particles adsorbed ndi omwazikana ndi kwambiri, madzi adzakhala turbid ndipo ngakhale kupanga flocs (panthawi ino, zotsatira zake ndi ofanana ndi flocculant). Poyerekeza ndi njira ya chelating, kubalalitsidwa ndikothandiza. Zotsatira zikuwonetsa kuti 1 mg dispersant imatha kupanga tinthu tating'ono ta 10-100 mg kukhalapo mokhazikika m'madzi ozungulira. M'madzi apakati komanso olimba kwambiri, dispersion of scale inhibitor imakhala ndi gawo lofunikira.

Kupindika kwa latisi

Pamene kuuma ndi alkalinity ya dongosolo ndi mkulu, ndipo chelating wothandizira ndi dispersant sikokwanira kuteteza mpweya wawo wathunthu, iwo mosalephera precipitate. Ngati palibe sikelo yolimba pamwamba pa chotenthetsera kutentha, sikelo imakula pamwamba pa chotenthetsera kutentha. Ngati pali dissperant yokwanira, tinthu tating'onoting'ono ( topangidwa ndi mazana a ma molekyulu a calcium carbonate) timamwa.
