Inhibitor yesikali

I-Scale inhibitor: inokusasaza iityuwa ze-inorganic ezinganyibilikiyo emanzini, ithintele okanye iphazamise imvula kunye nokukalwa kweetyuwa ezinganyibilikiyo kumphezulu wesinyithi, kwaye igcine isiphumo esihle sokuhambisa ubushushu besixhobo sesinyithi. Ukuveliswa kulungiswe ngokuthatha i-epoxy resin kunye ne-amino resin ethile njengezinto ezisisiseko, ukongeza inani elifanelekileyo lezongezo ezichasene ne-rust kunye ne-anti-corrosion ukwenza icandelo elinye. Inokukhusela okugqwesileyo, ukungagungqi, ukuxhathisa umhlwa, ukuxhathisa isikali esilungileyo, ukuhanjiswa kwe-thermal, ukuchasana okugqwesileyo kwi-asidi ebuthakathaka, i-alkali eyomeleleyo, i-solvents ye-organic kunye nezinye iipropati, i-adhesion eyomeleleyo, eqaqambileyo, eguquguqukayo, i-compact kunye nefilimu yepeyinti enzima.

Indlela yokuhlela esongwayo

Ukususela kwindlela ye-scale inhibitor, i-scale inhibition effect ye-scale inhibitor inokwahlulwa ibe yi-chelation, i-dispersion kunye ne-lattice distortion. Kuvavanyo lovavanyo lwaselabhoratri, ukusasazwa liyeza lesiphumo sokudityaniswa, kunye nesiphumo sokugqwesa i-lattice lunyango lwesiphumo sokusasazeka.

Iimpawu ezisebenzayo ze-high-reverse osmosis scale inhibitor esebenzayo

Akuyimfuneko ukongeza i-asidi eyongezelelweyo, enokuthi igweme ngokufanelekileyo ukubola kwezixhobo ngezinto ezi-acidic.

I-2 chelating effect izinzile, inokuthintela isinyithi, i-manganese kunye nezinye i-ion zetsimbi kwi-tube ye-membrane ukwenza ukungcola.

Ifanelekile kuzo zonke iintlobo zezixhobo ze-membrane ityhubhu.

Olona lawulo lothintelo lunoqoqosho lunokuphunyezwa ngedosi encinci kunye neendleko eziphantsi.

Inokunciphisa ukucocwa kwe-membrane kunye nokwandisa ubomi benkonzo ye-membrane.

Ukusonga i-chelation

I-Chelation yinkqubo apho i-ion ephakathi ibophelela kwii-athomu ezimbini okanye ngaphezulu zokulungelelaniswa kwe-polydentate ligand efanayo. Njengomphumo we-chelation, i-cations yokulinganisa (njenge-Ca2 +, i-Mg2 +) isabela kunye ne-chelating agents ukwenza i-chelates ezinzile, ezithintela ukudibanisa ne-anions yokulinganisa (njenge-CO32 -, i-SO42 -, i-PO43 - kunye ne-sio32 -), ngaloo ndlela inciphisa kakhulu amathuba okukala. I-Chelation yi-stoichiometric, umzekelo, ukubopha i-molecule ye-EDTA kwi-ion yensimbi ye-divalent.

Umthamo we-chelating we-chelating agents unokubonakaliswa ngexabiso le-chelating ye-calcium. Ngokubanzi, i-agent yonyango lwamanzi orhwebo (inxalenye enkulu yamacandelo asebenzayo alandelayo onke ama-50%, abalwa yi-CaCO3): i-aminotrimethylphosphonic acid (ATMP) - 300mg / g; i-diethylenetriamine pentamethylene phosphonic acid (dtpmp) - 450mg / g; ethylenediamine tetraacetic acid (EDTA) - 15om / g; i-hydroxyethyl diphosphonic acid (HEDP) - 45 OM. Ngamanye amagama, i-agent ye-1mg ye-chelating inokutshiza kuphela isikali se-calcium carbonate ngaphantsi kwe-0.5mg. Ukuba i-calcium kunye ne-magnesium ion kunye nobunzima obupheleleyo be-smm0fl kufuneka izinziswe kwinkqubo yamanzi ejikelezayo, i-agent efunekayo ye-chelating yi-1000m / L, eyongayo kwaye iyasebenza. Ke ngoko, igalelo le-scale inhibitor chelation liyinxalenye encinci kuphela. Nangona kunjalo, i-chelation ye-scale inhibitors idlala indima ebalulekileyo kumanzi aphakathi kunye nobunzima obuphantsi.

Ukusasazwa kokusasazwa

Isiphumo sokusasazeka kukuthintela ukudibana kunye ne-agglomeration yamasuntswana esikali se-oxide, ngaloo ndlela kuthintela ukukhula kwesikali se-oxide. Iinqununu ze-scaling zingaba yi-calcium kunye ne-magnesium ion, amakhulu e-CaCO3 kunye ne-MgCO3 iamolekyu, uthuli, i-sediment okanye ezinye izinto ezingenayo amanzi. I-Dispersant yipolymer enobunzima obuthile bemolekyuli (okanye iqondo lepolymerization), kwaye ukusasazwa kwayo kuhambelana ngokusondeleyo nobunzima bemolekyuli (okanye iqondo lepolymerization). Ukuba iqondo lepolymerization liphantsi kakhulu, inani leengqungquthela ezibhengezwayo kwaye zihlakazekile zincinci, kwaye ukusebenza kakuhle kwe-dispersion kuphantsi; ukuba iqondo le-polymerization liphezulu kakhulu, inani lamasuntswana adsorbed kwaye ahlakazekile kakhulu, amanzi aya kuba ne-turbid kwaye afake iiflocs (ngeli xesha, umphumo walo ufana ne-flocculant). Xa kuthelekiswa nendlela ye-chelating, ukusasazwa kuyasebenza. Iziphumo zibonisa ukuba i-1 mg dispersant inokwenza i-10-100 mg iincinci zesikali zikhona ngokuzinzileyo kumanzi ajikelezayo. Kumanzi aphakathi kunye nobunzima obuphezulu, i-dispersion of scale inhibitor idlala indima ebalulekileyo.

Ilathisi esongiwe ukugqwetheka

Xa ubunzima kunye ne-alkalinity yenkqubo iphezulu, kwaye i-agent ye-chelating kunye ne-dispersant ayanelanga ukukhusela imvula yabo epheleleyo, ngokuqinisekileyo baya kudlula. Ukuba akukho sikali esiqinileyo kumphezulu wobushushu, isikali siya kukhula kumphezulu wobushushu. Ukuba kukho i-dispersant eyaneleyo, amasuntswana okungcola (ahlanganiswe ngamakhulu e-calcium carbonate molekyuli) ayafunxwa.
