I-Scale inhibitor

I-Scale inhibitor: ingahlakaza usawoti we-inorganic ongancibiliki emanzini, ivimbele noma iphazamise ukuna nokukalwa kosawoti we-inorganic ongancibiliki endaweni yensimbi, futhi igcine umphumela omuhle wokudlulisa ukushisa kwempahla yensimbi. Ukusungulwa kulungiselelwa ngokuthatha i-epoxy resin kanye ne-amino resin ethize njengesisekelo sezinto, kwenezela inani elifanele lezithako ezihlukahlukene zokulwa nokugqwala kanye nezithasiselo zokulwa nokugqwala ukuze kwakhiwe ingxenye eyodwa. Inokuvikela okuhle kakhulu, ukungagxili, ukumelana nokugqwala, ukumelana nesilinganiso esihle, ukuguquguquka okushisayo, ukumelana okuhle kakhulu ne-asidi ebuthakathaka, i-alkali eqinile, izinyibilikisi ze-organic kanye nezinye izakhiwo, ukunamathela okuqinile, okukhanyayo, okuguquguqukayo, ifilimu yepende ehlangene neqinile.

Indlela yokuhlela yokugoqa

Kusukela kumshini we-scale inhibitor, umphumela wokuvimbela isikali we-scale inhibitor ungahlukaniswa ube yi-chelation, ukusabalalisa kanye nokuhlanekezela kwe-lattice. Esivivinyweni sokuhlolwa kwaselabhorethri, ukuhlakazeka kuyikhambi lomphumela wokuhlanganisa, futhi umphumela wokuhlanekezela we-lattice uwukhambi lomphumela wokuhlakazeka.

Izici ezisebenzayo ze-high performance reverse osmosis scale inhibitor

Akudingekile ukwengeza i-asidi eyengeziwe, engagwema ngokuphumelelayo ukugqwala kwemishini ngezinto ezine-acidic.

I-2 chelating effect izinzile, ingavimbela insimbi, i-manganese namanye ama-ion ensimbi ku-membrane tube ukwenza ukungcola.

Ilungele zonke izinhlobo zezinto zokwakha ze-membrane tube.

Ukulawulwa kokuvimbela isikali ukonga kakhulu kungafinyelelwa ngomthamo omncane kanye nezindleko eziphansi.

Kunganciphisa ukuhlanzwa kwe-membrane futhi kwandise impilo yesevisi ye-membrane.

Ukugoqa i-chelation

I-Chelation inqubo lapho i-ion emaphakathi ibophezela kuma-athomu amabili noma ngaphezulu wokuxhumanisa we-polydentate ligand efanayo. Njengomphumela we-chelation, ama-scaling cations (afana ne-Ca2 +, Mg2 +) asabela ngama-chelating agents ukuze enze ama-chelates azinzile, okubavimbela ukuthi baxhumane nama-anion wokukala (njenge-CO32 -, SO42 -, PO43 - ne-sio32 -), ngaleyo ndlela kunciphisa kakhulu amathuba okukala. I-Chelation i-stoichiometric, isibonelo, ukuboshwa kwe-molecule ye-EDTA ku-ion yensimbi ehlukanisiwe.

Amandla e-chelating we-chelating agents angavezwa inani le-calcium elicwengayo. Ngokuvamile, ama-ejenti okwelapha amanzi okuhweba (ingxenye enkulu yezingxenye ezilandelayo ezisebenzayo zonke ziyi-50%, ibalwa yi-CaCO3): i-aminotrimethylphosphonic acid (ATMP) - 300mg / g; i-diethylenetriamine pentamethylene phosphonic acid (dtpmp) - 450mg / g; i-ethylenediamine tetraacetic acid (EDTA) - 15om / g; i-hydroxyethyl diphosphonic acid (HEDP) - 45 OM. Ngamanye amazwi, i-ejenti ye-chelating engu-1mg ingakwazi kuphela i-chelate calcium carbonate esikalini esingaphansi kuka-0.5mg. Uma i-calcium ne-magnesium ions enobunzima obuphelele be-smm0fl idinga ukusimama ohlelweni lwamanzi ajikelezayo, i-ejenti yokuchela edingekayo ingu-1000m/L, okongayo futhi okusebenzayo. Ngakho-ke, umnikelo we-scale inhibitor chelation uyingxenye encane kuphela. Kodwa-ke, i-chelation of scale inhibitors idlala indima ebalulekile emanzini anobulukhuni obuphakathi naphansi.

Ukugoqa ukuhlakazeka

Umphumela wokuhlakazeka uwukuvimbela ukuthintana kanye ne-agglomeration yezinhlayiya zesikali se-oxide, ngaleyo ndlela kuvimbele ukukhula kwesikali se-oxide. Izinhlayiya zokukala zingaba i-calcium ne-magnesium ion, amakhulu ama-molecule e-CaCO3 ne-MgCO3, uthuli, intlenga noma ezinye izinto ezingancibiliki emanzini. I-Disperant i-polymer enesisindo esithile se-molecular (noma idigri ye-polymerization), futhi ukuhlakazeka kwayo kuhlobene eduze nesisindo samangqamuzana (noma idigri ye-polymerization). Uma izinga le-polymerization liphansi kakhulu, inani lezinhlayiya ezikhangisiwe nezihlakaziwe lincane, futhi ukusebenza kahle kokuhlakazeka kuphansi; uma izinga le-polymerization liphezulu kakhulu, inani lezinhlayiya ezikhangisiwe futhi ezihlakazekile likhulu kakhulu, amanzi azoba ne-turbid futhi enze ama-flocs (ngalesi sikhathi, umphumela wawo ufana nowe-flocculant). Uma kuqhathaniswa nendlela ye-chelating, ukusabalalisa kuyasebenza. Imiphumela ibonisa ukuthi i-1 mg dispersant ingenza izinhlayiya zesikali esingu-10-100 mg zibe khona ngokuzinza emanzini ajikelezayo. Emanzini anobulukhuni obuphakathi nendawo naphezulu, i-dispersion of scale inhibitor idlala indima ebalulekile.

Ukuhlanekezela kwe-lattice egoqiwe

Lapho ubulukhuni kanye ne-alkalinity yesistimu kuphezulu, futhi i-agent chelating kanye ne-dispersant akwanele ukuvimbela imvula yazo ephelele, nakanjani zizoncipha. Uma singekho isikali esiqinile ebusweni besishintshi sokushisa, isikali sizokhula phezu kwesishintshi sokushisa. Uma kune-disperant eyanele, izinhlayiya zokungcola (ezakhiwe ngamakhulu ama-molecule e-calcium carbonate) ziyamuncwa.
